Business
 
Overview
 
Following our recent business combination with OnCore Biopharma, Inc., (“OnCore”) we intend to focus our efforts on discovering, developing and commercializing a cure for patients suffering from chronic HBV infection, a disease of the liver caused by the hepatitis B virus. Our strategy incorporates our heritage and expertise in RNAi combined with the newly acquired assets and expertise through the OnCore merger.

We believe that, as a result of the merger, Tekmira will be well positioned to capitalize on the HBV global market opportunity. Our current HBV pipeline consists of 9 drugs and drug candidates, with eight unique mechanisms of action. Our unique strategy is to target the three pillars we believe are necessary to deliver an HBV cure, including: (i)  suppressing HBV viral replication, (ii) restoring host response by suppressing HBsAg or activating/stimulating the host immune system directed at HBV and (iii) eliminating covalently closed circular DNA (cccDNA), the reservoir of viral genomic material. We believe that our chances for success in HBV are increased, and risk is mitigated, by having a portfolio of assets targeting these three strategies. Most importantly, we believe combination therapies are the key to HBV treatment and a potential cure. We believe that clinical development can be accelerated when multiple components of a combination therapy regimen are controlled by the same company and therefore we have retained exclusive worldwide development and commercialization rights to all of our drug candidates and programs in HBV.
 
Recognized as a world leader in RNA interference (RNAi) delivery technology, Tekmira is a biopharmaceutical company that since inception has focused on advancing novel RNAi-based therapeutics. RNA interference is considered one of the most important discoveries in the field of biomedical science in the last decade. RNAi has the potential to generate a new class of therapies that take advantage of the body’s own natural processes to silence genes and, by extension, treat serious human diseases that often rely on the production of certain proteins at the genetic level. With this ability to eliminate disease-causing proteins from cells, RNAi therapies represent opportunities for therapeutic intervention that have not been achievable with conventional therapeutics.

Tekmira’s proprietary LNP Delivery Platform allows for the successful delivery and enablement of RNAi drugs. By encapsulating the RNAi trigger molecules in lipid nanoparticles (LNP); our LNP technology enables efficient delivery and uptake into target cells. Our LNP technology represents the most widely adopted delivery method in RNAi. To date, it has enabled eight clinical trials and has been administered to more than 250 patients. Recent results demonstrate that multi-dosing with LNP technology has been well-tolerated with treatments out to one year.
 
With anti-viral, oncology, and metabolic product platforms, our RNAi product pipeline is focused on areas where there is a significant medical need and commercial opportunity. Tekmira’s clinical and preclinical programs include RNAi therapeutics addressing chronic hepatitis B virus (HBV) infection, cancer indications such as gastrointestinal neuroendocrine tumors and adrenocortical carcinoma, and metabolic disorders such as hypertriglyceridemia.

Tekmira’s LNP technology also enables our partners’ development programs and pipelines, providing us with non-dilutive funding to support its internal therapeutic development programs. Because LNP can enable a wide variety of nucleic acid triggers, including messenger RNA (mRNA), we continue to seek new product development and partnering opportunities based on our industry-leading delivery expertise.
 
Corporate History
 
Tekmira was incorporated pursuant to the British Columbia Business Corporations Act (BCBCA), on October 6, 2005, and commenced active business on April 30, 2007, when Tekmira and its parent company, Inex Pharmaceuticals Corporation (“Inex”) were reorganized under a statutory plan of arrangement (the “Reorganization”) completed under the provisions of the BCBCA. The Reorganization saw Inex’s entire business transferred to and continued by Tekmira. In this discussion of corporate history the terms “we”, “us” and “our” refer to the business of Inex for the time prior to the Reorganization and the business of Tekmira for the time after the Reorganization.
 
Since 1992, we have focused on developing lipid delivery technologies for different classes of therapeutic agents, including chemotherapy drugs and nucleic acid drugs. Our technology was applied to the development of Marqibo®, a liposomal formulation of the chemotherapy drug vincristine, which was subsequently licensed to Hana Biosciences in 2006. Under this legacy agreement, our current licensee, Spectrum Pharmaceuticals, Inc., has a license to develop Marqibo, along with two other liposomal chemotherapy products.
 
Since 2005, Protiva Biotherapeutics, Inc. (“Protiva”) and Inex began separately developing lipid nanoparticle delivery technology for a class of nucleic acid drugs called RNAi trigger molecules that mediate RNA interference, or RNAi, and  both Protiva and Inex initiated separate research collaborations with Alnylam Pharmaceuticals, Inc. (“Alnylam”) to combine Alnylam’s expertise in RNAi trigger molecules or “trigger” technologies with each of Protiva’s and Inex’s separate proprietary knowledge of RNAi delivery technology.  In January 2007, Inex entered into a License and Collaboration Agreement with Alnylam where Inex obtained, among other things, a worldwide license to certain Alnylam intellectual property for the research, development, manufacturing and commercialization of RNAi products for the treatment of human diseases, and Alnylam obtained exclusive access to Inex’s delivery technology for siRNA and microRNA.  In August 2007, Protiva entered into a Cross License Agreement with Alnylam where Protiva obtained, among other things, a worldwide license to certain Alnylam intellectual property for the research, development, manufacturing and commercialization of RNAi products for the treatment of human diseases and Alnylam obtained non-exclusive access to Protiva’s delivery technology for siRNA and microRNA.
 
In 2008, Inex and Protiva entered into a business combination. At the time of its acquisition, Protiva was a private, venture-backed company incorporated under the laws of Canada and since 2003 had focused its business on developing lipid nanoparticle (LNP) delivery technology for RNAi, a business similar to Inex’s. Since commencing work on the delivery of RNAi triggers, Protiva has filed several patent applications covering different LNP formulations, manufacturing processes, and RNAi trigger design to remove any immune stimulatory properties. At the time of its acquisition, Protiva had licensed its LNP technology on a non-exclusive basis to Alnylam and (“Merck”) and had access to Alnylam’s intellectual property for the research, development and commercialization of RNAi products.

The business combination with Protiva was completed through an acquisition, under a share purchase agreement, of all the then outstanding shares of Protiva in consideration for common shares of Tekmira. Protiva is now Tekmira’s wholly-owned subsidiary. Concurrent with the completion of the business combination with Protiva, we entered into initial research agreements with F. Hoffman-La Roche Ltd and Hoffman La-Roche Inc., which we refer to together as (“Roche”), and completed private placement investments of $5.0 million with Alnylam and $5.0 million with an affiliate of Roche. Since the completion of the business combination with Protiva, Tekmira has focused on advancing RNAi therapeutic products and providing LNP delivery technology to pharmaceutical partners and collaborators using Protiva’s lipid technology.

In March of 2015, Tekmira completed a merger whereby OnCore Biopharma, Inc. (“OnCore”) became a wholly owned subsidiary of Tekmira.  As described in further detail below, Tekmira’s business strategy going forward intends to focus on discovering, developing and commercializing therapeutics targeting chronic hepatitis B infection, as well as continuing to advance our non-HBV programs as well.

Tekmira is headquartered in Vancouver, Canada, and it opened an office in Seattle, USA in May 2014.  As a result of the merger with OnCore, we also have offices in Doylestown, Pennsylvania, USA.

 Recent Developments
 
Business Combination between Tekmira and OnCore   

On March 4, 2015, Tekmira completed a business combination pursuant to which OnCore became a wholly-owned subsidiary of Tekmira.  This combined company intends to focus on developing a curative regimen for hepatitis B virus (HBV) patients by combining multiple therapeutic approaches. The transaction was approved by 99.5% of votes cast by Tekmira shareholders voting at a Special Meeting held on Tuesday, March 3, 2015, and representing 51.2% of Tekmira’s common shareholders. In connection with the transaction, Tekmira issued 23,973,315 common shares to the shareholders of OnCore in exchange for their OnCore securities, and OnCore became a wholly-owned subsidiary of Tekmira.

The new company's management team includes Mark J. Murray, PhD, President and Chief Executive Officer; Patrick T. Higgins, Chief Operating Officer; Bruce Cousins, Chief Financial Officer; Michael J. Sofia, PhD, Chief Scientific Officer; and Michael J. Abrams, PhD, Chief Discovery Officer. William T. Symonds, PharmD, is the Chief Development Officer and will lead the clinical development of the portfolio.

Vivek Ramaswamy is the Chairman of the Board for Tekmira. The remaining Board members are Dr. Mark J. Murray, Mr. Herbert Conrad, Mr. Richard Henriques, Dr. Keith Manchester, Mr. Frank Karbe, and Dr. William Symonds.

The business combination involving Tekmira and OnCore brings together each of Tekmira’s and OnCore’s broad expertise in antiviral drug development, Tekmira’s clinic-ready HBV RNAi therapeutic and OnCore’s existing HBV programs to build a portfolio of compounds with a long term goal of eradicating HBV. We believe that, as a result of the merger, Tekmira will have a comprehensive HBV pipeline of drugs, and drug candidates, and be positioned to capitalise on the HBV global market opportunity. With eight unique mechanisms in development, our pipeline targets the three pillars we believe are necessary to deliver an HBV cure, including: (i)  suppressing HBV viral replication, (ii) restoring host response by suppressing Hepatitis B surface antigen (HBsAg) or activating/stimulating the host immune system directed at HBV and (iii) eliminating covalently closed circular DNA (cccDNA). We believe that our chances for success in HBV are increased, and risk is mitigated, by having a portfolio of assets targeting these three strategies. Most importantly, we believe combination therapies are the key to HBV treatment and a potential cure. We believe that clinical development can be accelerated when multiple components of a combination therapy regimen are controlled by the same company, and therefore we have retained exclusive worldwide development and commercialization rights to all of our drug candidates and programs in HBV.

While we intend to focus our business strategy on HBV, we also believe that value resides in our other non-HBV programs and with our Lipid Nanoparticle (LNP) technology. We plan to determine what we believe are the best strategies for optimizing the value of the remaining assets. We also see significant value in the collaborations Tekmira has established to date, and plan to continue to work closely with and support our partners using Tekmira’s RNAi technology.

RNA Interference
 
In the last decade, RNAi has become one of the most important innovations in the field of drug discovery and development. In 2006 the scientists who discovered the mechanisms for RNAi were awarded the Nobel Prize in Physiology or Medicine.

We believe that RNAi has the potential to generate a new class of safer therapeutics. RNAi therapeutics take advantage of the body’s own natural processes to eliminate specific gene-products or proteins in the cell. Synthetic RNAi trigger molecules are developed as drugs that specifically suppress the production of disease-associated proteins through the RNAi mechanism. RNAi trigger molecules are designed using the gene sequence coding for the target protein. RNAi -based drugs are typically small synthetic nucleic acid molecules. When RNAi triggers are introduced into the cell they are incorporated into an RNA-induced silencing complex (RISC), which interacts specifically with messenger RNA (mRNA) coding for the target protein. mRNA are cleaved in a sequence specific manner and then destroyed, preventing production of the target protein. Importantly, this process is catalytic and RISC associated RNAi triggers can remain stable inside the cell for weeks, destroying many more copies of the target mRNA and maintaining target protein suppression for extended periods of time.
 
Potential of RNAi Therapeutics
 
The development of RNAi drugs allows for a completely novel approach to treating disease, which is why RNAi is considered one of the most promising and rapidly advancing frontiers in drug discovery. While there are no RNAi therapeutics approved for commercial use, there are a number of RNAi products currently in human clinical trials. RNAi products are broadly applicable as they can eliminate the production of disease-causing proteins from cells, creating opportunities for therapeutic intervention that have not been achievable with conventional drugs. Development of RNAi therapeutic products is currently limited by the instability of the RNAi trigger molecules in the bloodstream and the inability of these molecules to access target cells or tissues following administration. Delivery technology is necessary to protect these drugs in the bloodstream to allow efficient delivery and cellular uptake by the target cells.
 
  Tekmira’s Lipid Nanoparticle (LNP) Delivery Technology
 
Tekmira has developed a proprietary delivery platform called Lipid Nanoparticle or LNP. This platform has become the gold-standard in RNAi development, establishing Tekmira as a leader in this new area of innovative medicine.

Our proprietary LNP delivery technology allows for the successful encapsulation of RNAi trigger molecules in lipid nanoparticles (LNP) administered intravenously, which travel through the bloodstream to target tissues or disease sites. LNPs are designed to protect the triggers, and stay in the circulation long enough to accumulate at disease sites, such as the liver or cancerous tumors. LNPs are then taken up into the target cells by a process called endocytosis. Subsequent activation by the changing environment inside the cell causes the LNP to release the trigger molecules, which can then successfully mediate RNAi.

In preclinical studies, Tekmira’s LNP technology has demonstrated how it can overcome the limitations of RNAi drug delivery, enabling efficient and selective “gene silencing” or reduction of certain target proteins. We believe that Tekmira is well positioned to benefit from the need for effective delivery technology for RNAi therapeutics to reach specific disease sites. Using our LNP technology we, along with our partners, are advancing several RNAi therapeutics across a range of indications for serious conditions with limited treatment options.

Lipid Nanoparticle (LNP)-Enabled Delivery and Mechanism of RNA Interference
 
  * RISC is an RNA-induced silencing complex that incorporates one strand of siRNA or microRNA
 
Today, our LNP technology represents the most widely adopted delivery technology in RNAi, which has enabled eight clinical trials and has been administered to more than 250 human subjects. Because LNP can enable a wide variety of nucleic acid triggers, including mRNA, we continue to see new product development and partnering opportunities based on our industry-leading delivery expertise.

 In October 2013, we presented new preclinical data at the International mRNA Health Conference in Tubingen, Germany, demonstrating that mRNA when encapsulated and delivered using Tekmira’s LNP technology can be effectively delivered and expressed in the liver in tumors and other specific tissues of therapeutic interest.
 
 Our Product Pipeline
 
HBV-Focused Pipeline
 
Hepatitis B virus (HBV) causes the most common serious liver infection in the world. The World Health Organization (WHO) estimates that 350 million people worldwide are chronically infected, and other estimates suggest this could include up to 1.4 million people in the United States. Individuals chronically infected with HBV are at an increased risk of developing significant liver disease, including cirrhosis, or permanent scarring of the liver, as well as liver failure and hepatocellular carcinoma (HCC) or liver cancer. According to the Hepatitis B Foundation, HBV is the cause of up to 80% of liver cancers. Individuals with liver cancer typically have a five-year survival rate of only 15%. The WHO estimates that more than 780,000 people die every year due to the consequences of hepatitis B virus disease.

Our extensive experience in antiviral drug development has been applied to our TKM-HBV program to develop an RNAi therapeutic for chronic hepatitis B infection. Small molecule nucleotide therapy has been the standard of care for chronic HBV infected patients. However, many of these patients continue to express a viral protein called HBV surface antigen (HBsAg). This protein causes inflammation in the liver leading to cirrhosis and, in some cases, HCC and death.

As a result of our merger whereby OnCore became a wholly owned subsidiary of Tekmira, our pipeline of assets has expanded beyond therapeutics being developed with RNAi technology, particularly with respect to HBV. In HBV, we now have what we believe is an industry-leading pipeline focused on finding a cure for chronic HBV infection. Our belief is that to achieve an HBV cure, a combination of products that affect the three main drivers of HBV persistence need to be utilized. Specifically, this means that to be successful, we believe we need to have products that address antiviral replication, immune reactivation and reduce the pool of cccDNA.

Once multiple compounds within the portfolio with sufficient anti-HBV activity have been identified, we intend, subject to discussions with regulatory authorities, to conduct a rolling Phase II clinical program. These studies will likely evaluate combinations of two or more drug candidates in small cohorts of patients with chronic HBV infection to identify active combinations and those that do not have sufficient antiviral activity. We expect to use these results to adaptively design additional treatment regimens for the next cohorts. We also plan to evaluate different treatment durations to determine the optimal duration for a finite duration therapy. We plan to continue this iterative process until we select combination therapy regimens and treatment durations to conduct Phase III clinical trials intended to ultimately support regulatory filings for marketing approval.  A graphic summary of our HBV products is set forth below.

Note: The solid circles represent the mechanism that "directly" impacts the given persistence factor.  The shaded circle shows "indirect" effects of a given mechanism.  
 
We intend to continue to expand our HBV pipeline through internal development, acquisitions and in-licenses. We believe that a major engine for internal innovation is the collaboration entered into by OnCore, which is now a wholly owned subsidiary on Tekmira, with The Baruch S. Blumberg Institute, (“Blumberg”) one of the leading non-profit research institutes in the world focused on HBV.  We believe that this collaboration will provide us with access to cutting-edge research in new target identification, assay development, mechanism of action studies and lead-finding efforts focused on hepatitis B virus. This relationship also provides us with access to research that we believe is equal to, or surpasses that of other biotechnology or pharmaceutical companies, and can add value to our current and future research and development efforts in HBV.

TKM-HBV is designed to address an unmet medical need and eliminate HBsAg expression in patients chronically infected with HBV. Reducing HBsAg is thought to be a key prerequisite to enable a patient’s immune system to raise an adequate antibody response against the virus. The ability of TKM-HBV to inhibit numerous viral elements in addition to HBsAg increases the likelihood of successfully controlling the viral infection.

TKM-HBV is being developed as a multi-component RNAi therapeutic that simultaneously targets three sites on the HBV genome. Targeting three distinct and highly conserved sites on the HBV genome is intended to facilitate potent knockdown of all viral mRNA transcripts and viral antigens across a broad range of HBV genotypes and reduce the risk of developing antiviral resistance. The goal is for TKM-HBV to be administered without prophylactic steroid treatment.

We presented results from our preclinical studies at the 10th Annual Meeting of the Oligonucleotide Therapeutics Society Meeting held in San Diego, California, on October 15, 2014. Among the results reported is the potent and rapid reduction in HBsAg demonstrated by TKM-HBV in several well-validated models. In these models, TKM-HBV treatment resulted in reductions in both intrahepatic and serum HBsAg, as well as reductions in HBV DNA, covalently closed circular DNA (cccDNA), Hepatitis B e antigen and Hepatitis B c antigen. A rapid 1 log reduction in serum HBsAg was achieved with a single 1 mg/kg dose of TKM-HBV in the humanized mouse model, which closely mimics chronic human hepatitis B infection. 1-2 log viral reductions from similar single-dose LNP treatments in two other true-infection animal models were also demonstrated.

Preclinical studies conducted on infected primary human hepatocytes showed that TKM-HBV had robust and consistent activity against different viral strains representing the major clinical genotypes A, B, C and D. Our data shows that inclusion of three RNAi triggers results in a more broadly effective knockdown of hepatitis B viral elements than a single trigger alone. The mode of action of TKM-HBV complements standard of care nucleoside/nucleotide (NUC) therapy, and lack of drug antagonism has been demonstrated with entecavir, lamivudine and tenofovir on infected primary human hepatocytes, making combination therapy a viable option.

Our data supports the utility of TKM-HBV as a potential new therapeutic option for treating patients with chronic HBV infection. In early 2015, we advanced two TKM-HBV product candidates into a Phase I trial. Both product candidates employ the same unique combination of three RNAi trigger molecules. However, they differ in their LNP composition. One formulation employs a third generation LNP, and the other employs a new, fourth generation LNP, which incorporates novel lipid chemistry and demonstrates improved potency. The multi-component RNAi therapeutic is expected to result in broad and effective inhibition of HBV.

The TKM-HBV Phase I clinical trial is a randomized, single-blind, placebo-controlled study, involving single ascending doses of TKM-HBV. The study will assess the safety, tolerability and pharmacokinetics of intravenous administration of two formulations of TKM-HBV in healthy adult subjects. For each formulation, there are five planned cohorts for a total of 20 subjects (40 in total for both formulations). Four subjects will be enrolled per cohort with three subjects receiving TKM-HBV, and one receiving placebo. We expect the results from the Phase I clinical trial in healthy human volunteers to determine which product formulation we will advance into chronically infected patients in a multi-dosing trial in the second half of 2015.

Following our recent merger with OnCore, our product development pipeline will now focus on discovery, acquisition or in-licensing and developing drug candidates that attack multiple targets of the HBV lifecycle, including the aggressive suppression of HBV replication, restoration of an adequate immune response and reducing the pool of cccDNA. Although the ultimate curative regimens for HBV are currently unknown, we have assembled a robust portfolio of drug development programs targeting multiple targets within the HBV life cycle, which we plan to evaluate to determine the best potential combination approaches for patients.  These assets include the following:

Cyclophilin Inhibitor — OCB-030

Cyclophilins are proteins that have been shown to play a role in several biological processes, including viral infection. By inhibiting cyclophilin, we believe the ability of HBV to replicate can be impaired and the host immune response toward HBV may be enhanced. Through our OnCore subsidiary, we have licensed from NeuroVive Pharmaceutical AB, or “NeuroVive”, the exclusive rights to develop and commercialize cyclophilin inhibitor drug candidates, including OCB-030, for the treatment of hepatitis B. We are engaged in studies which we expect to be completed in order to file an IND, or equivalent, and initiate a study by year end 2015.

TLR9 Agonist (CYT-003)

Pharmaceutical activation of toll-like receptors (TLRs) is a novel and attractive approach for the treatment of chronic HBV because agonism of these receptors triggers innate immune responses and also stimulates adaptive immunity.  It is hoped that immune stimulation by TLR agonists can overcome the multiple immunologic blocks that allows chronic HBV infection, including direct activation of the host’s innate antiviral response, hence overcoming the functional weakness in HBV-specific immune cell responses.

Licensed from Cytos Bioetchnology Ltd. (“Cytos”), CYT-003 is a biological carrier which is filled with the immunostimulatory oligonucleotide called G10. G10 is a toll-like receptor-9 (TLR-9) agonist. CYT-003 has been shown to directly activate B cells and stimulates human pDC to secrete Interferon alpha. CYT-003 also activates other antigen presenting cells indirectly and promotes the development of TH1 type cytokine response. This is thought to be potentially beneficial in promoting anti-HBV T cell immunity. CYT-003 has previously been utilised in human trials in other indications and therefore could move quickly into the clinic in HBV infected patients. Preclinical studies to demonstrate proof of concept are anticipated to be initiated in 2015.

Capsid Assembly Inhibitors

We are developing two capsid assembly inhibitors as oral therapeutics for the treatment of chronic HBV infection. By inhibiting assembly of the viral capsid, the ability of hepatitis B virus to replicate is impaired, which subsequently reduces the amount of new virus produced, and may have an effect on cccDNA. Through our OnCore subsidiary, we have acquired exclusive, worldwide rights to these drug candidates through an in-license from Blumberg and Drexel University, or (“Drexel”), and through OnCore’s recent acquisition of Enantigen Therapeutics, Inc., or Enantigen.

Surface Antigen Secretion Inhibitors

We are developing multiple small molecule orally bioavailable HBV surface antigen secretion inhibitors. By inhibiting the secretion of HBV surface antigen from infected cells, we expect that the immune response of patients treated with this therapy can reengage and thereby mount a more credible response to a hepatitis B virus infection. We acquired these drug candidates through OnCore’s recent acquisition of Enantigen.

STING Agonists

We are developing STING (stimulator of interferon genes) agonists. By activating interferon genes, we anticipate that the body can produce additional interferon alpha and beta, which have antiviral properties. Our development program, which is currently in the discovery research stage, is based on proof of concept data in mice generated by Blumberg which showed that STING agonists can elicit an antiviral response and inhibit HBV replication in mouse liver cells. In collaboration with Blumberg, our plan is to identify potent, orally active small molecule human STING agonists that possess the desired characteristics to progress into human clinical studies.

cccDNA Formation Inhibitors

We are developing multiple series of cccDNA formation inhibitors. The inhibition of cccDNA formation would reduce the amount of cccDNA in the infected liver cell and could ultimately eliminate the reservoir of HBV genomic material required for continued viral replication. Through our OnCore subsidiary, we acquired the exclusive, worldwide rights to this program through an in-license from Blumberg. This program is currently in lead optimization.

cccDNA Epigenetic Modifiers

In addition to cccDNA formation inhibitors, we are developing cccDNA epigenetic modifiers. By controlling cccDNA transcription, we anticipate that we may be able to inhibit the formation of new virus and subviral particles from cccDNA. This development program, which is currently in the discovery research stage, is based on proof of concept data generated by Blumberg using known inhibitors of enzymes involved in DNA information processing.
 
Non-HBV Assets – Clinical Programs and Pre-Clinical Programs (LNP enabled)

We believe there is significant value in our non-HBV assets and remain committed to maximizing this value. We intend to continue our clinical programs to the appropriate point in support of this objective. We also remain interested in advancing our ongoing metabolic and rare disease preclinical programs in an appropriate way toward this value maximization objective and in continuing to leverage our knowledge and expertise in LNP technology. A graphic summary of our non-HBV products is set forth below.
 

Our RNAi product pipeline is focused on anti-virals, oncology and metabolic product platforms, where there is a significant medical need and commercial opportunity. Our intention is to advance our RNAi product pipeline either ourselves or with partners, with a focus on realizing the value of these assets.
 
We believe that our LNP technology is a leading technology for formulating novel RNAi and mRNA products. The use of the technology in these fields has the potential to enable a broad new class of therapeutics. Our LNP technology currently represents the most widely adopted and advanced delivery technology in RNAi, having enabled eight clinical trials and with administration to over 250 patients to date. LNP and RNAi technology has the potential to generate a broad new class of therapeutics that take advantage of the body’s own natural processes to silence genes — or more specifically to eliminate specific gene-products, from the cell.
 
We are also committed to continuing to support the work of our product development partners and intellectual property licensees with the goal of realizing the short-term and long term financial potential of these partnerships.

TKM-PLK1
 
Our oncology product platform, TKM-PLK1, targets polo-like kinase 1 (PLK1), a protein involved in tumor cell proliferation and a validated oncology target. Inhibition of PLK1 expression prevents the tumor cell from completing cell division, resulting in cell cycle arrest and death of the cancer cell. Evidence that patients with elevated levels of PLK1 in their tumors exhibit poorer prognosis and survival rates has been documented in the medical literature. TKM-PLK1 is being evaluated in oncology indications in which there are limited or ineffective therapies available: Gastrointestinal Neuroendocrine Tumors (GI-NET), Adrenocortical Carcinoma (ACC) and Hepatocellular Carcinoma (HCC).

GI-NET and ACC
 
GI-NET is the gastrointestinal subset of neuroendocrine tumors. According to a paper by Yao et al. (2008), a historical analysis of the US SEER database reveals the incidence of neuroendocrine tumors has increased faster in the last few decades than any other neoplasm, with a growth rate of greater than 3% expected to continue in the near term. The prevalence of GI-NET in the US is estimated to be approximately 55,000 individuals. Prognosis for advanced or metastatic GI-NET, the target population for TKM-PLK1, is poor with 25-54% of patients surviving less than one year.

ACC is an ultra-rare form of cancer that develops in the adrenal gland, with data from the US National Cancer Institute estimating 500 patients in the US. Survival prognosis for these patients is poor. A large percentage of patients are not good surgical candidates and there is a lack of effective systemic therapies.

We presented updated Phase I TKM-PLK1 data at the 6th Annual NET Conference hosted by the North American Neuroendocrine Tumor Society (NA-NETS) in Charleston, South Carolina on October 4, 2013. This data set included a total of 36 patients in a population of advanced cancer patients with solid tumors. Doses ranged from 0.15 mg/kg to 0.90 mg/kg during the dose escalation portion of the trial, with the maximum tolerated dose (MTD) of 0.75 mg/kg. Serious adverse events (SAEs) were experienced by four subjects in this heavily pre-treated, advanced cancer patient population, with three of four subjects continuing on study. Forty percent (6 out of 15) of patients evaluable for response, treated at a dose equal to or greater than 0.6 mg/kg, showed clinical benefit. Three out of the four ACC patients (75%) treated with TKM-PLK1 achieved stable disease, including one patient who saw a 19.3% reduction in target tumor size after two cycles of treatment and is still on study receiving TKM-PLK1. Of the two GI-NET patients enrolled, both experienced clinical benefit: one patient had a partial response based on Response Evaluation Criteria in Solid Tumors (RECIST) criteria, and the other GI-NET patient achieved stable disease and showed a greater than 50% reduction in Chromogranin-A (CgA) levels, a key biomarker used to predict clinical outcome and tumor response.
 
Based on encouraging results from the dose escalation portion and expansion cohort from our Phase I TKM-PLK1 clinical trial, we expanded into a Phase I/II clinical trial with TKM-PLK1, which is specifically enrolling patients within two therapeutic indications: advanced GI-NET or ACC. This multi-center, single arm, open label study is designed to measure efficacy using RECIST criteria for GI-NET patients and ACC patients as well as evaluate the safety, tolerability and pharmacokinetics of TKM-PLK1. TKM-PLK1 is administered weekly with each four-week cycle consisting of three once-weekly doses followed by a rest week. In the Fall of 2014, we achieved our enrolment target of patients with advanced GI-NET or ACC tumors. These patients will continue treatment and be followed to determine if TKM-PLK1 produces a meaningful clinical benefit.

We provided an update on this Phase I/II clinical study in December 2014. To date, 55 patients, in both the Phase I and Phase I/II studies have been treated at doses of ≥ 0.6 mg/kg, which is considered to be in the efficacious dose range based on preclinical studies. Of these, 31 patients comprise the target population of GI-NET or ACC patients. Currently, nine patients (GI-NET and ACC) remain actively on treatment and data collection is ongoing.

While we are still awaiting maturation of data, we continue to see evidence of anti-tumor activity in some treated subjects, including one ACC patient with an almost complete resolution of their disease. We expect to report final data from these studies in the second half of 2015.
 
HCC

HCC is one of the most common cancers and one of the most deadly, with over 650,000 deaths each year worldwide according to the Globocan 2012 database.  US incidence is estimated at 27,000 individuals with annual growth rates greater than 2%. HCC is an aggressive, hard-to-treat disease with one-year survival rates of less than 50% and five-year rates as low as 4% (National Cancer Institute). To date, Nexavar® (sorafenib) is the only agent approved to treat HCC with an improvement in overall survival of just two to three months.
 
In May 2014, we initiated another Phase I/II clinical trial with TKM-PLK1, enrolling patients with advanced HCC. Patient dosing has commenced and we have completed the first treatment in all of our subjects for the first HCC cohort. This Phase I/II clinical trial is a multi-center, single arm, open label dose escalation study designed to evaluate the safety, tolerability and pharmacokinetics of TKM-PLK1 as well as determine the maximum tolerated dose in patients with advanced HCC. It will also include a preliminary assessment of the anti-tumor activity of TKM-PLK1 in this patient population. It is expected that approximately 38 patients with advanced HCC tumors will be enrolled in this Phase I/II clinical trial.

TKM-Ebola

TKM-Ebola, an anti-Ebola RNAi therapeutic, is being developed under a $140 million contract, signed in July 2010, with the U.S. Department of Defense (DoD) Joint Project Manager Medical Countermeasure Systems BioDefense Therapeutics (JPM-MCS-BDTX). Preclinical studies published in the medical journal The Lancet in 2010 demonstrated that when RNAi triggers targeting the Ebola virus and delivered by our LNP technology were used to treat previously infected non-human primates, the result was 100 percent protection from an otherwise lethal dose of Zaire Ebola virus (Geisbert et al., The Lancet, Vol. 375, May 29, 2010).
 
12

 
In May 2013, our collaboration with the JPM-MCS-BDTX was modified and expanded to include advances in LNP formulation technology. The contract modification increased the first stage of funding from $34.7 million to $41.7 million. In April 2014, we signed a second contract modification to increase this funding by $2.1 million to a total of $43.8 million to compensate Tekmira for unrecovered costs that occurred in 2012 and to provide additional funding should it be required.
 
TKM-Ebola is being developed under specific U.S. Food and Drug Administration (FDA) regulatory guidelines called the “Animal Rule”. This allows, in circumstances where it is unethical or not feasible to conduct human efficacy studies, marketing approval to be granted based on adequate and well-controlled animal studies when the results of those studies establish that the drug is reasonably likely to produce clinical benefit in humans. Demonstration of the product’s safety in humans is still required.
 
We were granted Fast Track designation from the FDA for the development of TKM-Ebola in March 2014. The FDA’s Fast Track is a process designed to facilitate the development and expedite the review of drugs in order to get important new therapies to the patient earlier.

In May 2014, we successfully completed the single ascending dose portion of the TKM-Ebola Phase I clinical trial in healthy human volunteers. Results demonstrated that administration of the TKM-Ebola therapeutic, in the absence of any steroid containing pre-medication, was well-tolerated at a dose level of 0.3 mg/kg, determined to be the maximum tolerated dose.

In July 2014, we received notice from the FDA placing the TKM-Ebola Investigational New Drug application (IND) on clinical hold until additional information is supplied, and the multiple ascending dose portion of the trial protocol is modified to ensure the safety of healthy volunteers. The clinical hold was subsequently modified to a partial clinical hold to permit the administration of TKM-Ebola to patients with a suspected or confirmed Ebola virus infection. Under the FDA’s expanded access program, several patients with a confirmed or suspected Ebola virus infection were treated with TKM-Ebola. Data is being collected and will be provided to the FDA under our IND. Health Canada also established a similar framework for the potential use of TKM-Ebola in the same group of patients.

With the emergency use of our TKM-Ebola product under expanded access protocols and recent developments, such as the production of a new product candidate for clinical trials in West Africa, the clinical development pathways for our Ebola products are evolving. We may not be able to resolve the partial clinical hold of the healthy volunteer, multiple ascending dose portion of our Phase 1 trial of TKM-Ebola.

In December 2014, the US Congress amended the Rare and Tropical Disease list to include Ebola as a candidate for a potential Accelerated Review Voucher.
 
TKM-Ebola-Guinea, an Anti-Ebola RNAi Therapeutic Targeting Ebola-Guinea Strain of Ebola Virus

In September 2014, we joined an international consortium led by the International Severe Acute Respiratory and Emerging Infection Consortium (ISARIC) at the University of Oxford, UK, to potentially provide an RNAi based investigational therapeutic for expedited clinical studies in West Africa.

In October 2014, the genomic sequence of the Ebola-Guinea strain, which is the virus responsible for the recent outbreak in West Africa, was determined from several viral isolates and published in the New England Journal of Medicine (Baize S., et al. Emergence of Zaire Ebola Virus Disease in Guinea; New England Journal of Medicine, October 9, 2014 Vol. 371 No. 15). We rapidly developed a modified RNAi therapeutic to specifically target Ebola-Guinea. The new product, TKM-Ebola-Guinea, is designed to match the genomic sequence exactly, with two RNAi molecule triggers. Results of preclinical studies with TKM-Ebola-Guinea demonstrated efficacy comparable to those obtained with TKM-Ebola, which demonstrated up to 100% protection from an otherwise lethal dose of the virus.

In December 2014, we entered into a Manufacturing and Clinical Trial Agreement with the University of Oxford to provide the new TKM-Ebola-Guinea therapeutic product for clinical studies in West Africa. ISARIC can conduct clinical studies of TKM-Ebola-Guinea in Ebola virus infected patients, with funding provided by the Wellcome Trust. GMP manufacture of TKM-Ebola-Guinea is now complete and 100 treatment courses are available for the study. A Phase II single arm trial called RAPIDE (Rapid Assessment of Potential Interventions & Drugs for Ebola), was initiated in March 2015 in Sierra Leone. The study is open-label with a concurrent observational study in Ebola virus disease, and results are expected in the second half of 2015.

The U.S. Department of Defense JPM-MCS-BDTX has also exercised an option, valued at $7.0 million, in our current contract to manufacture TKM-Ebola-Guinea. We have been awarded the option for scale-up and GMP manufacture of the product for approximately 500 treatment courses.

Non-HBV Preclinical Programs (LNP enabled)

We are currently evaluating several additional preclinical candidates with potential in diverse therapeutic areas. Given the extremely high efficiency of delivery for third and fourth generation liver-centric LNP formulations, we are focused on rare diseases where the molecular target is found in the liver, early clinical proof-of-concept can be achieved and development opportunities may be accelerated. Our research team intends to continue to generate preclinical data to support the advancement of the most promising of these targets.

TKM-Marburg 

Like Ebola, Marburg is a member of the filovirus family of hemorrhagic fever viruses. Natural outbreaks with the Marburg-Angola strain have resulted in mortality in approximately 90% of infected individuals. There are currently no approved therapeutics available for the treatment of Marburg infection.

In 2010, along with the University of Texas Medical Branch (UTMB), we were awarded a National Institutes of Health (NIH) grant to support research to develop RNAi therapeutics to treat Ebola and Marburg hemorrhagic fever viral infections. In November 2013, we announced data showing 100% survival in non-human primates infected with the Angola strain of the Marburg virus in two separate studies. These results build upon a study published earlier in the Journal of Infectious Disease showing 100% protection in guinea pig models of infection with Angola, Ci67 and Ravn strains of the Marburg virus using a broad spectrum RNAi therapeutic enabled by Tekmira’s LNP.

In February 2014, along with UTMB, and other collaborators, we were awarded additional funding from the NIH in support of this research. Data was published demonstrating complete protection of non-human primates against lethal Marburg-Angola strain, (Science Translational Medicine. Thi EP., et al. Marburg virus infection in nonhuman primates: Therapeutic treatment by lipid-encapsulated siRNA. 2014 Aug 20;6 (250))
 
Non-HBV Preclinical Programs (LNP enabled)

We are currently evaluating several additional preclinical candidates with potential in diverse therapeutic areas. Given the extremely high efficiency of delivery for third and fourth generation liver-centric LNP formulations, we are focused on rare diseases where the molecular target is found in the liver, early clinical proof-of-concept can be achieved and development opportunities may be accelerated. Our research team intends to continue to generate preclinical data to support the advancement of the most promising of these targets.
 
 TKM-HTG

Our metabolic product platform, TKM-HTG, aims to achieve rapid and sustained reductions of triglycerides to address the limitations of existing Hypertriglyceridemia (HTG) treatments. Hypertriglyceridemia is a type of dyslipidemia where there are high blood levels of triglycerides. Patients with severe HTG, (classified as triglyceride levels greater than 1000 mg/dL) are at risk of acute pancreatitis as well as the risk of cardiovascular disease. Approximately one million adults in the US and 18 million worldwide suffer from severe HTG. (NHANES 2003-2004 data).

Another patient group affected by HTG are those with Familial Chylomicronemia Syndrome (FCS), which is a very rare hereditary condition affecting an estimated 1:1,000,000 people (www.fcs.raredr.com). Additionally, 35% of patients with Type 2 Diabetes (T2D) suffer from mixed hyperlipidemia which is a combination of elevated cholesterol and high triglycerides. With underlying T2D, these patients are at considerable risk from cardiovascular disease.

TKM-HTG is being developed as a multi-component RNAi therapeutic that simultaneously targets a combination of genes expressed in the liver, which are known to play a significant role in triglyceride metabolism. High triglyceride levels are medically linked to increased risk of cardiovascular disease, fatty liver disease, insulin resistance and pancreatitis.

We anticipate filing an investigational new drug application, or equivalent document, in the second half of 2015.

 TKM-ALDH
 
TKM-ALDH is designed to knockdown or silence aldehyde dehydrogenase (ALDH) to induce long term acute sensitivity to ethanol, for use in severe alcohol use disorder. Aldehyde dehydrogenase is a key enzyme in ethanol metabolism. Inhibition of ALDH activity, through the silencing of ALDH, results in the build-up of acetaldehyde leading to adverse physiological effects. Human proof of concept for ALDH inhibition already exists in the form of the approved drug disulfiram. However, disulfiram’s efficacy is compromised by poor compliance because it has to be taken daily. We believe TKM-ALDH will induce prolonged ethanol sensitivity that will enable it to overcome the compliance limitations associated with daily dosing. We are exploring partnering or external funding opportunities to maximize the value of this asset.
 
Ongoing Advancements in LNP Technology

We plan to continue to develop our proprietary LNP delivery technology and receive clinical validation from LNP-based products currently in clinical trials. The most advanced LNP-enabled therapeutic, which is being developed by Alnylam, has entered a Phase III clinical trial. We believe our LNP technology can remain an important cornerstone of our business development activities moving forward. We recently announced the latest (fourth) generation of the platform which comprises a rational re-design of the lipid architecture, as well as formulation and process advances. These attributes can be utilized in programs entering the clinic in 2015 and are expected to yield significant increases in potency and therapeutic index.
 
 
14

 
Because LNP can enable a wide variety of nucleic acid triggers, including mRNA, we continue to see new product development and partnering opportunities based on what we believe is our industry-leading delivery expertise. In February 2014, we presented new preclinical data at the AsiaTIDES scientific symposium in Tokyo, Japan demonstrating that mRNA can be effectively delivered to target proteins expressed. 
 
Partner-Based Programs

 
 
Patisiran (ALN-TTR02)

Patisiran, or ALN-TTR02, which is being developed by Alnylam, represents the most clinically advanced application of our proprietary LNP delivery technology. In November 2013, Alnylam presented positive results from its Phase II clinical trial with patisiran (ALN-TTR02), an RNAi therapeutic targeting transthyretin (TTR) for the treatment of TTR-mediated amyloidosis (ATTR). In December 2013, Alnylam announced the initiation of the APOLLO Phase III trial of patisiran to evaluate efficacy and safety of patisiran in ATTR patients with Familial Amyloidotic Polyneuropathy (FAP). In April 2014, Alnylam presented positive new data from its Phase II clinical trial with patisiran. These results provide additional support for Alnylam's Phase III APOLLO trial. In October 2014, Alnylam reported positive clinical data for the ongoing patisiran Phase II Open Label Extension (OLE) study in patients with FAP. The results demonstrated sustained knockdown of serum TTR of up to 90% and a favorable tolerability profile out to one year of treatment.

Alnylam has also pursued two other LNP-based products through clinical development: ALN-VSP (liver cancer), and ALN-PCS02 (hypercholesterolemia). Alnylam will pay Tekmira low single digit royalties based on commercial sales of Alnylam’s LNP-enabled products. More information about our licensing agreement with Alnylam can be found under the “Strategic Alliances, Licensing Agreements, and Research Collaborations” section of this report.
 
Marqibo® 

Marqibo®, originally developed by Tekmira, is a novel, sphingomyelin/cholesterol liposome-encapsulated formulation of the FDA-approved anticancer drug vincristine. Marqibo’s approved indication is for the treatment of adult patients with Philadelphia chromosome-negative acute lymphoblastic leukemia (Ph-ALL) in second or greater relapse or whose disease has progressed following two or more lines of anti-leukemia therapy. Our licensee, Spectrum Pharmaceuticals, Inc. (“Spectrum”), launched Marqibo through its existing hematology sales force in the United States. We are entitled to mid-single digit royalty payments based on Marqibo’s commercial sales. Spectrum has ongoing trials evaluating Marqibo in three additional indications, which are: first line use in patients with Philadelphia Negative Acute Lymphoblastic Leukemia (Ph-ALL), Pediatric ALL and Non-Hodgkin’s lymphoma. More information about our licensing agreement with Spectrum can be found under the “Strategic Alliances, Licensing Agreements, and Research Collaborations” section of this report.
 
DCR-PH1

In November 2014, we signed a licensing and collaboration agreement with Dicerna Pharmaceuticals, Inc. to utilize our LNP delivery technology exclusively in Dicerna's primary hyperoxaluria type 1 (PH1) development program. Dicerna will use our third generation LNP technology for delivery of DCR-PH1, Dicerna's product incorporating its Dicer substrate RNA (DsiRNA) molecule, for the treatment of PH1, a rare, inherited liver disorder that often results in kidney failure and for which there are no approved therapies. More information about our licensing agreement with Dicerna can be found under the “Strategic Alliances, Licensing Agreements, and Research Collaborations” section of this report.
 
Strategic Alliances, Licensing Agreements, and Research Collaborations
 
Since inception, we have fostered collaborations and technology licensing relationships with leading companies in the RNAi field, including Alnylam Pharmaceuticals, Inc., Bristol-Myers Squibb Company, Merck & Co. Inc., the U.S. Department of Defense’s BioDefense Therapeutics’ Office, Monsanto, Dicerna Pharmaceuticals Inc., and other undisclosed pharmaceutical and biotechnology companies.
 
 
15

 
We have certain rights under the RNAi intellectual property of Alnylam Pharmaceuticals, Inc. to develop 13 RNAi therapeutic products. In addition, we have a broad non-exclusive license to use Unlocked Nucleobase Analogs (UNAs) from Arcturus Therapeutics, Inc. (“Arcturus”) for the development of RNAi therapeutic products directed to any target in any therapeutic indication.
 
Alnylam Pharmaceuticals, Inc. (“Alnylam”) and Acuitas Therapeutics Inc. (“Acuitas”)
 
In November 2012, we, Alnylam, and AlCana Technologies, Inc. (now Acuitas Therapeutics Inc.) entered into an agreement to settle all litigation and to restructure the existing contractual relationship, replacing all earlier licensing, cross-licensing, collaboration, and manufacturing agreements. Consistent with the terms outlined in the 2012 settlement agreement, in December 2013, we finalized and entered a cross-license agreement with Acuitas. The terms provide Acuitas with access to certain of our earlier Intellectual Property (IP) generated prior to April 2010, and provide us with certain access to their technology and licenses in the RNAi field, along with a percentage of each milestone, and royalty payment with respect to certain products. In addition, Acuitas has agreed that it will not compete in the RNAi field for a period of five years.

As a result of the settlement and 2012 cross-license agreement, we received a total of $65 million in cash payments from Alnylam in November 2012. This included $30 million associated with the termination of the manufacturing agreement and $35 million associated with the termination of the previous Alnylam-Inex and Alnylam-Protiva license agreements, as well as a reduction of the milestone and royalty schedules associated with Alnylam’s ALN-VSP, ALN-PCS, and ALN-TTR programs. Of the $65 million received from Alnylam, $18.7 million was subsequently paid by us to our lead legal counsel, in satisfaction of the contingent obligation owed to that counsel. In addition, Alnylam transferred all agreed upon patents and patent applications related to LNP technology for the systemic delivery of RNAi therapeutic products, including the MC3 lipid family, which is used in Alnylam’s TTR-mediated amyloidosis treatment ALN-TTR02, to Tekmira. As a result, we own and control prosecution of this IP portfolio. We are the only company able to sublicense LNP intellectual property in future platform-type relationships. Alnylam has a license to use our IP to develop and commercialize products and may only grant access to our LNP technology to its partners if the partner is part of a product sublicense. Alnylam’s license rights are limited to patents that we filed, or that claim priority to a patent that was filed, before April 15, 2010. Alnylam does not have rights to our patents filed on or after April 15, 2010 unless they claim priority to a patent filed before that date. Alnylam will pay us low single digit royalties based on commercial sales of Alnylam’s LNP-enabled products using our technology, including ALN-TTR02 (patisiran), ALN-VSP, and ALN-PCS02.

 The 2012 cross-license agreement with Alnylam also grants us IP rights to develop our own proprietary RNAi therapeutics. Alnylam has granted us a worldwide license for the discovery, development and commercialization of RNAi products directed to 13 gene targets – three exclusive and ten non-exclusive licenses – provided that they have not been committed by Alnylam to a third party, or are otherwise unavailable as a result of the exercise of a right of first refusal held by a third party, or are part of an ongoing or planned development program of Alnylam. Licenses for five of the 10 non-exclusive targets – ApoB, PLK1, Ebola, WEE1, and CSN5 – have already been granted, along with an additional license for ALDH2, which has been granted on an exclusive basis. In consideration for this license, we have agreed to pay single-digit royalties to Alnylam on product sales and have milestone obligations of up to $8.5 million on the non-exclusive licenses (with the exception of TKM-Ebola, which has no milestone obligations). Alnylam no longer has “opt-in” rights to our lead oncology product, TKM-PLK1, so we now hold all development and commercialization rights related TKM-PLK1. We will have no milestone obligations on the three exclusive licenses.
 
In December 2013, we received a $5.0 million milestone from Alnylam, triggered by the initiation of the APOLLO Phase III trial of patisiran. We have entered an arbitration proceeding with Alnylam, as provided for under our licensing agreement, to resolve a matter related to a disputed $5.0 million milestone payment payable to us by Alnylam for its ALN-VSP product. We have not recorded any revenue in respect of this milestone.

Merck & Co., Inc. ("Merck") and Alnylam license agreement
 
As a result of the business collaboration with Protiva in 2008, we acquired a non-exclusive royalty-bearing worldwide license agreement with Merck. Under the license, Merck will pay up to $17.0 million in milestones for each product they develop covered by Protiva’s IP, except for the first product for which Merck will pay up to $15.0 million in milestones, and will pay royalties on product sales. Merck’s license rights are limited to patents that we filed, or that claim priority to a patent that was filed, before October 9, 2008. Merck does not have rights to our patents filed after October 9, 2008 unless they claim priority to a patent filed before that date. Merck has also granted a license to us to certain of its patents.  On March 6, 2014, Alnylam announced that they acquired all assets and licenses from Merck, which included our license agreement.

Dicerna Pharmaceuticals, Inc. (“Dicerna”)

In November 2014, Tekmira signed a licensing agreement and a development and supply agreement with Dicerna to license Tekmira's LNP delivery technology for exclusive use in Dicerna's primary hyperoxaluria type 1 (PH1) development program. Dicerna will use Tekmira's third generation LNP technology for delivery of DCR-PH1, Dicerna's product incorporating its Dicer substrate RNA (DsiRNA) molecule, for the treatment of PH1, a rare, inherited liver disorder that often results in kidney failure and for which there are no approved therapies. Under the agreements, Dicerna paid Tekmira $2.5 million upfront and will potentially make payments of $22 million in aggregate development milestones, plus a mid-single-digit royalty on future PH1 sales. This partnership also includes a supply agreement under which we will provide clinical drug supply and regulatory support for the rapid advancement of this product candidate.

Monsanto Company (“Monsanto”)
 
In January 2014, we signed an Option Agreement and a Service Agreement with Monsanto, pursuant to which Monsanto may obtain a license to use our proprietary delivery technology. The transaction supports the application of our proprietary delivery technology and related IP for use in agriculture. The potential value of the transaction could reach $86.2 million following the successful completion of milestones. In January 2014, we received $14.5 million of the $17.5 million in anticipated near term payments. We received additional payments of $1.5 M each in June 2014 and October 2014 following achievement of specific program objectives.

Spectrum Pharmaceuticals, Inc. (“Spectrum”)

In July 2013, Talon Therapeutics Inc. (formerly Hana Biosciences, Inc.) was acquired by Spectrum. Under a legacy license agreement, Spectrum has an exclusive license to three targeted chemotherapy products originally developed by us. Marqibo® (optisomal vincristine), Alocrest® (optisomal vinorelbine) and Brakiva® (optisomal topotecan). Spectrum will pay us milestones and single-digit royalties and is responsible for all future development and expenses.
 
We are eligible to receive milestone payments from Spectrum up to $18.0 million upon achievement of further development and regulatory milestones, as well as single-digit royalties based on product sales. If Spectrum sublicenses any of the product candidates, we are eligible to receive a percentage of any upfront fees or milestone payments received by Spectrum. On September 18, 2014, Spectrum announced that they have sublicensed rights to sell Marqibo in the Greater China region to CASI Pharmaceuticals, Inc. (“CASI”). CASI issued a promissory note for $1.5 million as up-front consideration for the sublicense. The promissory note is payable on March 17, 2016 at which time Spectrum will pay a portion to us. Depending on the royalty rates Spectrum receives from its sub-licensees, our royalty rate may be lower on product sales by the sub-licensees. The royalty rate will be reduced to low single digits if there is generic competition.
 
Marqibo is a novel, sphingomyelin/cholesterol liposome-encapsulated formulation of the FDA-approved anticancer drug vincristine originally developed by Tekmira. In September 2013, we announced that our licensee, Spectrum had launched Marqibo through its existing hematology sales force in the United States. Since then commercial sales have occurred. We are entitled to mid-single digit royalty payments based on Marqibo’s commercial sales. 

Marina Biotech, Inc. (“Marina”) /Arcturus Therapeutics, Inc. (“Arcturus”)
 
In November 2012, we disclosed that we had obtained a worldwide, non-exclusive license to a novel RNAi trigger technology called Unlocked Nucleobase Analog (UNA) from Marina for the development of RNAi therapeutics. UNAs can be incorporated into RNAi drugs and have the potential to improve them by increasing their stability and reducing off-target effects. In August 2013, Marina assigned its UNA technology to Arcturus and the UNA license agreement between Tekmira and Marina was assigned to Arcturus. The terms of the license are otherwise unchanged.

To date, we have paid Marina $0.5 million in license fees and there are milestones of up to $3.2 million plus royalties for each product that we develop using UNA technology licensed from Marina.  We announced on January 21, 2015, that we had initiated a Phase I clinical trial with TKM-HBV. As TKM-HBV utilizes UNA technology in-licensed from Arcturus, the initiation of the trial triggered a single milestone payment of $250,000 payable by us to Arcturus.

U.S. National Institutes of Health (“NIH”)
 
In October 2010, we announced that together with collaborators at The University of Texas Medical Branch (UTMB), we were awarded a new NIH grant to support research to develop RNAi therapeutics to treat Ebola and Marburg hemorrhagic fever viral infections using our LNP delivery technology.  The grant, worth $2.4 million, is supporting work at Tekmira and at UTMB. In February 2014, we along with UTMB, and other collaborators, were awarded additional funding from the NIH in support of this research. Under this grant, we will receive $3.4 million over a period of five years.

Bristol-Myers Squibb Company (“BMS”)
 
In May 2010, we announced a research collaboration with BMS. Under this agreement, BMS conducted preclinical work to validate the function of certain genes and shared the data with us to potentially develop RNAi therapeutic drugs against therapeutic targets of interest. We formulated the required RNAi trigger molecules enabled by our LNP technology to silence target genes of interest.  BMS paid us $3.0 million concurrent with the signing of the agreement. We provided a predetermined number of LNP batches over the four-year agreement.  In May 2011, we announced a further expansion of the collaboration to include broader applications of our LNP technology and additional target validation work. In May 2014, the collaboration expired and both parties’ obligations ended. Recognition of revenue from agreements with BMS is covered in the Revenue section of this MD&A.

Halo-Bio RNAi Therapeutics, Inc. (“Halo-Bio”)
 
In August 2011, we entered into a license and collaboration agreement with Halo-Bio. Under the agreement, Halo-Bio granted to us an exclusive license to its multivalent ribonucleic acid MV-RNA technology. The agreement was amended on August 8, 2012, to adjust future license fees and other contingent payments. To date, we have recorded $0.5 million in fees under our license from Halo-Bio. We terminated the agreement with Halo-Bio on July 31, 2013. There are no further payments due or contingently payable to Halo-Bio.
 
Aradigm Corporation (“Aradigm”)
 
In December 2004, we entered into a licensing agreement with Aradigm under which Aradigm exclusively licensed certain of our liposomal intellectual property for the pulmonary delivery of Ciprofloxacin. As amended, this agreement calls for milestone payments totalling $4.5 and $4.75 million, respectively, for the first two disease indications pursued by Aradigm using our technology, and for low- to mid-single-digit royalties on sales revenue from products using our technology. We terminated the Aradigm license agreement in May 2013.
 
University of British Columbia (“UBC”)

Certain early work on lipid nanoparticle delivery systems and related inventions was undertaken at the University of British Columbia (UBC). These inventions are licensed to us by UBC under a license agreement, initially entered in 1998 and as amended in 2001, 2006 and 2007. We have granted sublicenses under the UBC license to Alnylam as well as to Talon.  Alnylam has in turn sublicensed back to us under the licensed UBC patents for discovery, development and commercialization of RNAi products. In mid-2009, we and our subsidiary Protiva entered into a supplemental agreement with UBC, Alnylam and Acuitas, in relation to a separate research collaboration to be conducted among UBC, Alnylam and Acuitas to which we have license rights. The settlement agreement signed in late 2012 to resolve the litigation among Alnylam, Acuitas, Tekmira and Protiva provided for the effective termination of all obligations under such supplemental agreement as between and among all litigants.

  On November 10, 2014, the University of British Columbia filed a demand for arbitration against Tekmira Pharmaceuticals Corp., BCICAC File No.: DCA-1623.  We received UBC’s Statement of Claims on January 16, 2015.  In its Statement of Claims, UBC alleges that it is entitled to $3.5 million in allegedly unpaid royalties based on publicly available information, and an unspecified amount based on non-public information.  UBC also seeks interest and costs, including legal fees. Tekmira disputes UBC’s allegation.  No dates have been scheduled for this arbitration.

Newly acquired assets as a result of our merger with OnCore
 
In addition to the newly acquired product candidates discussed above, our merger with OnCore resulted in the acquisition of the following:

Cytos Biotechnology Ltd (“Cytos”)
 
On December 30, 2014, OnCore entered into an exclusive, worldwide, sub-licensable (subject to certain restrictions with respect to licensed viral infections other than hepatitis) license to six different series of compounds. The licensed compounds are Qbeta-derived virus-like particles that encapsulate TLR9, TLR7 or RIG-I agonists and may or may not be conjugated with antigens from hepatitis virus or other licensed viruses.  We have an option to expand this license to include additional viral infections other than influenza and Cytos will retain all rights for influenza, all non-viral infections, and all viral infections (other than hepatitis) for which we have not exercised an option. 
 
In partial consideration for this license, upon closing of the Cytos Agreement we will be obligated to pay Cytos up to a total of $67 million for each of the six licensed compound series upon the achievement of specified development and regulatory milestones for hepatitis; and each additional licensed viral infection, up to a total of $110 million upon the achievement of specified sales performance milestones; and tiered royalty payments in the high-single to low-double digits, based upon the proportionate net sales of licensed products in any commercialized combination.
 
 
The Baruch S. Blumberg Institute (“Blumberg”) and Drexel University (“Drexel”)

In February 2014, OnCore entered into a license agreement with Blumberg and Drexel that granted us an exclusive (except as to certain know-how and subject to retained non-commercial research rights), worldwide, sub-licensable license to three different compound series: cccDNA inhibitors, capsid assembly inhibitors and HCC inhibitors.
 
In partial consideration for this license, OnCore paid a license initiation fee of $150,000 and issued warrants to Blumberg and Drexel. Under this license agreement, OnCore also agreed to pay up to $3.5 million in development and regulatory milestones per licensed compound series, up to $92.5 million in sales performance milestones per licensed product, and royalties in the mid-single digits based upon the proportionate net sales of licensed products in any commercialized combination. We are obligated to pay Blumberg and Drexel a double digit percentage of all amounts received from the sub-licensees, subject to customary exclusions.
 
 
18

 
In November 2014, OnCore entered into an additional license agreement with Blumberg and Drexel pursuant to which OnCore received an exclusive (subject to retained non-commercial research rights), worldwide, sub-licensable license under specified patents and know-how controlled by Blumberg and Drexel covering epigenetic modifiers of cccDNA and STING agonists. In consideration for these exclusive licenses, OnCore made an upfront payment of $50,000. Under this agreement, we will be required to pay up to $1.0 million for each licensed product upon the achievement of a specified regulatory milestone and a low single digit royalty, based upon the proportionate net sales of compounds covered by this intellectual property in any commercialized combination. We are also obligated to pay Blumberg and Drexel a double digit percentage of all amounts received from its sub-licensees, subject to exclusions. 
 
Acquisition of Enantigen Therapeutics, Inc. (“Enantigen”)
 
In October 2014, OnCore acquired all of the outstanding shares of Enantigen pursuant to a stock purchase agreement. Through this transaction, OnCore acquired a HBV surface antigen secretion inhibitor program and a capsid assembly inhibitor program, each of which are now assets of Tekmira, following the merger with OnCore.
 
Under the stock purchase agreement, we agreed to pay to Enantigen’s selling stockholders up to a total of $21.0 million upon the achievement of specified development and regulatory milestones for the first two products that contain either a capsid compound, or a HBV surface antigen compound that is covered by a patent that acquired under this agreement, or a capsid compound from an agreed upon list of compounds, up to a total of $101.5 million in sales performance milestones in connection with the sale of the first commercialized product of Tekmira for the treatment of HBV, regardless of whether such product is based upon assets acquired under this agreement; and low single digit royalty on net sales of such first commercialized HBV product, up to a maximum royalty payment of $1.0 million that, if paid, would be offset against our milestone payment obligations.
 
License Agreements between Enantigen and Blumberg and Drexel
 
Under the stock purchase agreement, we also agreed to that Enantigen would fulfill its obligations under Enantigen’s three patent license agreements with Blumberg and Drexel. Pursuant to each patent license agreement, Enantigen is obligated to pay Blumberg and Drexel up to approximately $500,000 in development and regulatory milestones per licensed product, royalties in the low single digits, and a percentage of revenue it receives from its sub-licensees.
 
Research Collaboration and Funding Agreement with Blumberg

In October 2014, OnCore entered into a research collaboration and funding agreement with Blumberg under which we will provide $1.0 million per year of research funding for three years, renewable at our option for an additional three years, for Blumberg to conduct research projects in HBV and liver cancer pursuant to a research plan to be agreed upon by the parties. Blumberg has exclusivity obligations to Tekmira with respect to HBV research funded under the agreement. In addition, we have the right to match any third party offer to fund HBV research that falls outside the scope of the research being funded under the agreement. Blumberg has granted us the right to obtain an exclusive, royalty bearing, worldwide license to any intellectual property generated by any funded research project. If we elect to exercise our right to obtain such a license, we will have a specified period of time to negotiate and enter into a mutually agreeable license agreement with Blumberg. This license agreement will include the following pre negotiated upfront, milestone and royalty payments: an upfront payment in the amount of $100,000; up to $8.1 million upon the achievement of specified development and regulatory milestones; up to $92.5 million upon the achievement of specified commercialization milestones; and royalties at a low single to mid-single digit rates based upon the proportionate net sales of licensed products from any commercialized combination.
 
NeuroVive Pharmaceutical AB (“NeuroVive”)
 
In September 2014, OnCore entered into a license agreement with NeuroVive that granted us an exclusive, worldwide, sub-licensable license to develop, manufacture and commercialize, for the treatment of HBV, oral dosage form sanglifehrin based cyclophilin inhibitors (including OCB-030). Under this license agreement we have been granted a non-exclusive, royalty free right and license and right of reference to NeuroVive’s relevant regulatory approvals and filings for the sole purpose of developing, manufacturing and commercializing licensed products for the treatment of HBV. Under this license agreement, we have (1) an option to expand our exclusive license to include treatment of viral diseases other than HBV and (2) an option, exercisable upon specified conditions, to expand our exclusive license to include development, manufacture and commercialization of non-oral variations of licensed products for treatment of viral diseases other than HBV. NeuroVive retains all rights with respect to development, manufacture and commercialization of licensed products and non-oral variations of licensed products for all indications (other than HBV) for which we have not exercised our option.
 
In partial consideration for this license, OnCore paid NeuroVive a license fee of $1 million. We are also obligated to pay up to $47.0 million in clinical development and regulatory milestones per indication and up to $102.5 million in sales performance milestones per licensed product and indication. If we are acquired by a third party in a transaction that meets certain criteria, then we or our acquiror will be obligated to pay all remaining development, regulatory and sales milestone payments, regardless of whether the applicable milestone events have been achieved, for each licensed product that entered clinical development before such acquisition. We agreed to pay NeuroVive tiered royalties in the mid-single to low-double digit range based upon the proportionate gross sales of patented licensed products from any commercialized combination. If we terminate this license agreement in its entirety for convenience prior to the first commercial sale of any licensed product, we will be obligated to pay NeuroVive $2 million.

Patents and Proprietary Rights

Our commercial success depends in part on our ability to obtain and maintain proprietary protection for our drug candidates, novel discoveries, product development technologies and other know-how, to operate without infringing on the proprietary rights of others and to prevent others from infringing our proprietary rights. Our policy is to seek to protect our proprietary position by, among other methods, filing or in licensing U.S. and foreign patents and patent applications related to our proprietary technology, inventions and improvements that are important to the development and implementation of our business. We also rely on trademarks, trade secrets, know how, continuing technological innovation and potential in licensing opportunities to develop and maintain our proprietary position.

In addition to our proprietary expertise, we own a portfolio of patents and patent applications directed to LNP inventions, the formulation and manufacture of LNP-based pharmaceuticals, chemical modification of RNAi molecules, and RNAi drugs and processes directed at particular disease indications. We have filed many patent applications with the US and European Patent Offices that have been granted. In the US our patents might be challenged by interference or opposition proceedings. In Europe, upon grant, a period of nine months is allowed for notification of opposition to such granted patents.  If our patents are subjected to interference or opposition proceedings, we would incur significant costs to defend them. Further, our failure to prevail in any such proceedings could limit the patent protection available to our RNAi platform, including our product candidates.
 
We have a portfolio of approximately 95 patent families, in the U.S. and abroad, that are directed to various aspects of LNPs and LNP formulations. The portfolio includes approximately 72 issued U.S. patents, approximately 71 issued non-U.S. patents, and approximately 229 pending patent applications, including the following patents and applications in the United States and Europe (1) :

Patent information current as of January 8, 2015.
*
Priority filing dates are based on the filing dates of provisional patent applications. Provisional applications expire unless they are converted to non-provisional applications within one year.
**
An “allowed” patent application is an active case that has been found by the patent office to contain patentable subject matter, subject to the payment of issue/grant fees by the applicant.
*** Once issued, the term of a US patent first filed after mid-1995 generally extends until the 20th anniversary of the filing date of the first non-provisional application to which such patent claims priority. It is important to note, however, that the United States Patent & Trademark Office, or USPTO, sometimes requires the filing of a Terminal Disclaimer during prosecution, which may shorten the term of the patent. On the other hand, certain patent term adjustments may be available based on USPTO delays during prosecution. Similarly, in the pharmaceutical area, certain patent term extensions may be available based on the history of the drug in clinical trials. We cannot predict whether or not any such adjustments or extensions will be available or the length of any such adjustments or extensions.
       
Through our wholly-owned subsidiary, OnCore, we also have licenses to numerous patents and patent applications relating to HBV drug candidates, methods of manufacturing and development, diagnosis, treatment or prevention of hepatitis viruses in humans, among others.

Employees
 
At December 31, 2014, Tekmira had 103 employees, 75 of whom were engaged in research and development. As a result of our recent merger with OnCore, we are adding 11 additional employees.  None of our employees are represented by a labor union or covered by a collective bargaining agreement, nor have we experienced any work stoppages. We believe that relations with our employees are good.

Corporate information
 
The company is comprised of six entities, Tekmira Pharmaceuticals Corporation (“Tekmira” or “we” or “us”) and five wholly owned subsidiaries (Protiva Biotherapeutics Inc., Protiva Agricultural Development Company Inc., Protiva Biotherapeutics (USA) Inc., OnCore Biopharma, Inc and Enantigen Therapeutics, Inc). Tekmira was incorporated pursuant to the British Columbia Business Corporations Act, or BCBCA, on October 6, 2005 and commenced active business on April 30, 2007 when Tekmira and its parent company, Inex Pharmaceuticals Corporation, or Inex, were reorganized under a statutory plan of arrangement (the Reorganization) completed under the provisions of the BCBCA. The Reorganization saw Inex’s entire business transferred to and continued by Tekmira. Protiva Biotherapeutics Inc., is incorporated under the BCBCA and was acquired by Tekmira Pharmaceuticals Corporation on May 30, 2008. Protiva Biotherapeutics (USA) Inc., is incorporated in the State of Delaware and was acquired by Tekmira Pharmaceuticals Corporation on May 30, 2008. Protiva Agricultural Development Company Inc., is incorporated under the BCBCA and was formed on January 9, 2014. On March 4, 2015, we completed a business combination with OnCore Biopharma, Inc., that is intended to create a leading global hepatitis B virus (HBV) company focused on developing a curative regimen for HBV patients by combining multiple therapeutic approaches. OnCore has one subsidiary, Enantigen Therapeutics, Inc.
 
Tekmira’s head office and principal place of business is located at 100—8900 Glenlyon Parkway, Burnaby, British Columbia, Canada, V5J 5J8 (telephone: (604) 419-3200). The Company’s registered and records office is located at 700 West Georgia St, 25th Floor, Vancouver, British Columbia, Canada, V7Y 1B3. The address of the Seattle office is 1100 Dexter Ave N.

Item 1A.
Risk Factors
 
Our business is subject to numerous risks. We caution you that the following important factors, among others, could cause our actual results to differ materially from those expressed in forward-looking statements made by us or on our behalf in filings with the SEC, press releases, communications with investors and oral statements. All statements other than statements relating to historical matters should be considered forward-looking statements. When used in this report, the words “believe,” “expect,” “plan,” “anticipate,” “estimate,” “predict,” “may” “could” “should,” “intend,” “will,” “target,” “goal” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these words. Any or all of our forward-looking statements in this annual report on Form 10-K and in any other public statements we make may turn out to be wrong. They can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties. Many factors mentioned in the discussion below will be important in determining future results. Consequently, no forward-looking statement can be guaranteed. Actual future results may vary materially from those anticipated in forward-looking statements. We explicitly disclaim any obligation to update any forward-looking statements to reflect events or circumstances that arise after the date hereof. You are advised, however, to consult any further disclosure we make in our reports filed with the SEC.

Risks Related to Our Business
 
We are in the early stages of our development and because we have a short development history with ribonucleic acid interference (RNAi) and assets relating to HBV, there is a limited amount of information about us upon which you can evaluate our RNAi business and prospects, and our HBV business and prospects.
 
We have not begun to market or generate revenues from the commercialization of any RNAi products or our HBV products. We have only a limited history upon which one can evaluate our business and prospects as our therapeutic products are still at an early stage of development and thus we have limited experience and have not yet demonstrated an ability to successfully overcome many of the risks and uncertainties frequently encountered by companies in new and rapidly evolving fields, particularly in the biopharmaceutical area. For example, to execute our business plan, we will need to successfully:
 
 
·
execute research and development activities using RNAi technology; and technologies involved in the development of HBV therapeutics;
 
·
build, maintain and protect a strong intellectual property portfolio;
 
·
gain acceptance for the development and commercialization of any product we develop;
 
·
develop and maintain successful strategic relationships; and
 
·
manage our spending and cash requirements as our expenses are expected to increase due to research and preclinical work, clinical trials, regulatory approvals, and commercialization and maintaining our intellectual property portfolio
 
If we are unsuccessful in accomplishing these objectives, we may not be able to develop products, raise capital, expand our business or continue our operations.
 
The approach we are taking to discover and develop novel drug products is unproven and may never lead to marketable drug products.
 
We intend to concentrate our internal research and development efforts in the future primarily on the discovery and development of therapeutics targeting chronic hepatitis B to be able to ultimately develop a cure for the disease. Our future success depends in part on the successful development of these therapeutics.
 
Our approach to the treatment of HBV is unproven, and we do not know whether we will be able to develop any drugs of commercial value.
 
There is no known cure for HBV. Any compounds that we develop may not effectively address the three key factors driving HBV persistence that we believe should be targeted in order to cure HBV. Even if we are able to develop compounds that address one or more of these key factors, targeting these key factors has not been proven to cure HBV. Further, our focus on the elimination of cccDNA as the critical component of developing a cure for HBV may be misplaced in the event that the elimination of cccDNA does not prove to contribute to a cure for HBV. In addition, we may be unable to develop a drug that successfully eliminates cccDNA. We may be unable to acquire additional drug candidates on terms acceptable to us, or at all. Even if we are able to acquire or develop drug candidates that address one of these mechanisms of action in preclinical studies, we may not succeed in demonstrating safety and efficacy of the drug candidate in human clinical trials. If we are unable to identify suitable compounds for preclinical and clinical development, we will not succeed in realizing our goal of a cure for HBV.

 
22

 
We also intend to continue research and development efforts on RNAi technology and products based on RNAi technology. While RNAi technology is based on a naturally occurring process that takes place inside cells, which can suppress the production of specific proteins, and has the potential to generate therapeutic drugs that take advantage of that process, neither we nor any other company has received regulatory approval to market a therapeutic product based on RNAi technology. The scientific discoveries that form the basis for our efforts to discover and develop new products are relatively new. While there are a number of RNAi therapeutics in development, very few product candidates based on these discoveries have ever been tested in humans and there can be no assurance that any RNAi therapeutic product will be approved for commercial use.
 
If we are not successful in developing a product with our research and development efforts, we may be required to change the scope and direction of our product development activities. In that case, we may not be able to identify and implement successfully an alternative product development strategy.
 
We expect to depend in part on our existing collaborators for a significant portion of our revenues and to develop, conduct clinical trials with, obtain regulatory approvals for, and manufacture, market and sell some of our product candidates. If these collaborations are unsuccessful, or anticipated milestone payments are not received, our business could be adversely affected.
 
We expect that we will depend in part on Alnylam, Spectrum, the DoD, and Monsanto to provide revenue to fund our operations, especially in the near term. The DoD represented 63% of our operating revenue for the year ended December 31, 2014. Furthermore, our strategy is to enter into various additional arrangements with corporate and academic collaborators, licensors, licensees and others for the research, development, clinical testing, manufacturing, marketing and commercialization of our products. We may be unable to continue to establish such collaborations, and any collaborative arrangements we do establish may be unsuccessful, or we may not receive milestone payments as anticipated.
 
Should any collaborative partner fail to develop or ultimately successfully commercialize any of the products to which it has obtained rights, our business may be adversely affected. In addition, once initiated, there can be no assurance that any of these collaborations will be continued or result in successfully commercialized products. Failure of a collaborative partner to continue funding any particular program could delay or halt the development or commercialization of any products arising out of such program. In addition, there can be no assurance that the collaborative partners will not pursue alternative technologies or develop alternative products either on their own or in collaboration with others, including our competitors, as a means for developing treatments for the diseases targeted by our programs.
 
We expect to spend substantial amounts to acquire additional drug candidates, to conduct further research and development and preclinical testing and clinical trials of our drug candidates, to seek regulatory approvals for our drug candidates and to launch and commercialize any drug candidates for which we receive regulatory approval. These expenditures will include costs associated with our and our subsidiary’s licensing agreements with Blumberg, or Drexel, and NeuroVive and Cytos. Under the terms of these agreements, we are obligated to make significant cash payments upon the achievement of specified development, regulatory and sales performance milestones, as well as royalty payments in connection with the sale of licensed products, to our licensors.
 
We expect the DoD to fund our TKM-Ebola program through to completion of a Phase 1 human safety clinical trial and possibly beyond that to FDA drug approval. The quantum and timing of funding may not be what we have projected and the DoD could cancel this funding at any time.
 
We have a contract with the DoD for $43.8 million for our TKM-Ebola program through to the completion of a Phase 1 human safety clinical trial and certain manufacturing objectives. The DoD may later extend the contract to cover the entire TKM-Ebola program through to FDA drug approval.
 
This is our first DoD contract of any notable size. Our lack of experience in dealing with the DoD brings uncertainty into our cash flow projections and uncertainty into our ability to execute the contract within DoD requirements. Furthermore, there is inherent risk in projecting cash flows years ahead for such a complex program. The quantum and timing of funding for the TKM-Ebola program may not be what we have projected and under the terms of the contract or the proposed modification to the contract and the DoD could cancel or suspend this funding, which is paid through monthly reimbursements, at any time.
 
We rely on third parties to conduct our clinical trials, and if they fail to fulfill their obligations, our development plans may be adversely affected.
 
We rely on independent clinical investigators, contract research organizations and other third-party service providers to assist us in managing, monitoring and otherwise carrying out our clinical trials. We have contracted with, and we plan to continue to contract with, certain third parties to provide certain services, including site selection, enrolment, monitoring and data management services. Although we depend heavily on these parties, we do not control them and therefore, we cannot be assured that these third parties will adequately perform all of their contractual obligations to us. If our third-party service providers cannot adequately fulfill their obligations to us on a timely and satisfactory basis or if the quality or accuracy of our clinical trial data is compromised due to failure to adhere to our protocols or regulatory requirements, or if such third parties otherwise fail to meet deadlines, our development plans may be delayed or terminated.

We have no sales, marketing or distribution experience and would have to invest significant financial and management resources to establish these capabilities.
 
We have no sales, marketing or distribution experience. We currently expect to rely heavily on third parties to launch and market certain of our products, if approved. However, if we elect to develop internal sales, distribution and marketing capabilities, we will need to invest significant financial and management resources. For products where we decide to perform sales, marketing and distribution functions ourselves, we could face a number of additional risks, including:
 
 
·
we may not be able to attract and build a significant marketing or sales force;
 
·
the cost of establishing a marketing or sales force may not be justifiable in light of the revenues generated by any particular product; and
 
·
our direct sales and marketing efforts may not be successful.
 
If we are unable to develop our own sales, marketing and distribution capabilities, we will not be able to successfully commercialize our products, if approved, without reliance on third parties.
 
We will rely on third-party manufacturers to manufacture our products (if approved) in commercial quantities, which could delay, prevent or increase the costs associated with the future commercialization of our products.
 
Our product candidates have not yet been manufactured for commercial use. If any of our product candidates become approved for commercial sale, in order to supply our or our collaborators’ commercial requirements for such an approved product, we will need to establish third-party manufacturing capacity. Any third-party manufacturing partner may be required to fund capital improvements to support the scale-up of manufacturing and related activities. The third-party manufacturer may not be able to establish scaled manufacturing capacity for an approved product in a timely or economic manner, if at all. If a manufacturer is unable to provide commercial quantities of such an approved product, we will have to successfully transfer manufacturing technology to a new manufacturer. Engaging a new manufacturer for such an approved product could require us to conduct comparative studies or utilize other means to determine bioequivalence of the new and prior manufacturers’ products, which could delay or prevent our ability to commercialize such an approved product. If any of these manufacturers is unable or unwilling to increase its manufacturing capacity or if we are unable to establish alternative arrangements on a timely basis or on acceptable terms, the development and commercialization of such an approved product may be delayed or there may be a shortage in supply. Any inability to manufacture our products in sufficient quantities when needed would seriously harm our business.
 
Manufacturers of our approved products, if any, must comply with current good manufacturing practices (cGMP) requirements enforced by the FDA and Health Canada through facilities inspection programs. These requirements include quality control, quality assurance, and the maintenance of records and documentation. Manufacturers of our approved products, if any, may be unable to comply with these cGMP requirements and with other FDA, Health Canada, state, and foreign regulatory requirements. We have little control over our manufacturers’ compliance with these regulations and standards. A failure to comply with these requirements may result in fines and civil penalties, suspension of production, suspension or delay in product approval, product seizure or recall, or withdrawal of product approval. If the safety of any quantities supplied is compromised due to our manufacturer’s failure to adhere to applicable laws or for other reasons, we may not be able to obtain regulatory approval for or successfully commercialize our products, which would seriously harm our business.
  
Risks Related to Our Financial Results and Need for Financing
 
We will require substantial additional capital to fund our operations. If additional capital is not available, we may need to delay, limit or eliminate our research, development and commercialization processes and may need to undertake a restructuring.
 
Within the next several years, substantial additional funds will be required to continue with the active development of our pipeline products and technologies. In particular, our funding needs may vary depending on a number of factors including:
 
 
·
revenues earned from our partners, including Alnylam, Spectrum, Monsanto, and Dicerna;
 
·
revenues earned from our DoD contract to develop TKM-Ebola;
 
·
the extent to which we continue the development of our product candidates or form collaborative relationships to advance our products;
 
·
our decisions to in-license or acquire additional products or technology for development,
 
·
our ability to attract and retain corporate partners, and their effectiveness in carrying out the development and ultimate commercialization of our product candidates;
 
·
whether batches of drugs that we manufacture fail to meet specifications resulting in delays and investigational and remanufacturing costs;
 
·
the decisions, and the timing of decisions, made by health regulatory agencies regarding our technology and products;
 
·
competing technological and market developments; and
 
·
prosecuting and enforcing our patent claims and other intellectual property rights.
 
 
24

 
We will seek to obtain funding to maintain and advance our business from a variety of sources including public or private equity or debt financing, collaborative arrangements with pharmaceutical and biotechnology companies and government grants and contracts. There can be no assurance that funding will be available at all or on acceptable terms to permit further development of our products especially in light of the current difficult climate for investment in early stage biotechnology companies.
 
If adequate funding is not available, we may be required to delay, reduce or eliminate one or more of our research or development programs or reduce expenses associated with non-core activities. We may need to obtain funds through arrangements with collaborators or others that may require us to relinquish most or all of our rights to product candidates at an earlier stage of development or on less favorable terms than we would otherwise seek if we were better funded. Insufficient financing may also mean failing to prosecute our patents or relinquishing rights to some of our technologies that we would otherwise develop or commercialize.
 
We have incurred losses in nearly every year since our inception and we anticipate that we will not achieve sustained profits for the foreseeable future. To date, we have had no product revenues.
 
With the exception of the year ended December 31, 2006 and December 31, 2012, we have incurred losses each fiscal year since inception until December 31, 2014 and have not received any revenues other than from research and development collaborations, license fees and milestone payments. From inception to December 31, 2014, we have an accumulated net deficit of $ 206 million. As we continue our research and development and clinical trials and seek regulatory approval for the sale of our product candidates, we do not expect to attain sustained profitability for the foreseeable future. We do not expect to achieve sustained profits until such time as strategic alliance payments, product sales and royalty payments, if any, generate sufficient revenues to fund our continuing operations. We cannot predict if we will ever achieve profitability and, if we do, we may not be able to remain consistently profitable or increase our profitability.

Risks Related to Managing Our Operations
 
If we are unable to attract and retain qualified key management, scientific staff, consultants and advisors, our ability to implement our business plan may be adversely affected.
 
We depend upon our senior executive officers as well as key scientific, management and other personnel. The competition for qualified personnel in the biotechnology field is intense. We rely heavily on our ability to attract and retain qualified managerial, scientific and technical staff. The loss of the service of any of the members of our senior management, including Dr. Mark Murray, our Chief Executive Officer, may adversely affect our ability to develop our technology, add to our pipeline, advance our product candidates and manage our operations.

We may have difficulty managing our growth and expanding our operations successfully as we seek to evolve from a company primarily involved in discovery and preclinical testing into one that develops products through clinical development and commercialization.
 
As product candidates we develop enter and advance through clinical trials, we will need to expand our development, regulatory, manufacturing, clinical and medical capabilities or contract with other organizations to provide these capabilities for us. As our operations expand, we expect that we will need to manage additional relationships with various collaborators, suppliers and other organizations. Our ability to manage our operations and growth will require us to continue to improve our operational, financial and management controls, reporting systems and procedures. We may not be able to implement improvements to our management information and control systems in an efficient or timely manner and may discover deficiencies in existing systems or controls.
 
We could face liability from our controlled use of hazardous and radioactive materials in our research and development processes.
 
We use certain radioactive materials, biological materials and chemicals, including organic solvents, acids and gases stored under pressure, in our research and development activities. Our use of radioactive materials is regulated by the Canadian Nuclear Safety Commission for the possession, transfer, import, export, use, storage, handling and disposal of radioactive materials. Our use of biological materials and chemicals, including the use, manufacture, storage, handling and disposal of such materials and certain waste products is regulated by a number of federal, provincial and local laws and regulations. Although we believe that our safety procedures for handling such materials comply with the standards prescribed by such laws and regulations, the risk of accidental contamination or injury from these materials cannot be completely eliminated. In the event of such an accident, we could be held liable for any damages that result and any such liability could exceed our resources. We are not specifically insured with respect to this liability.
 
Our business and operations could suffer in the event of information technology system failures.
 
Despite the implementation of security measures, our internal computer systems and those of our contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war, and telecommunication and electrical failures. Such events could cause interruption of our operations. For example, the loss of pre-clinical trial data or data from completed or ongoing clinical trials for our product candidates could result in delays in our regulatory filings and development efforts and significantly increase our costs. To the extent that any disruption or security breach will result in a loss of or damage to our data, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the development of our product candidates could be delayed.
 
 
25

 
If, in the future, our internal control over financial reporting is not effective, it could have a material adverse effect on our stock price and our ability to raise capital.
 
We have completed an independent audit of our internal control over financial reporting for our fiscal year ending December 31, 2014 and no material weaknesses have been identified. If our internal control over financial reporting is determined in the future to not be effective, whether by our management or by our independent auditors, there could be an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements, which could materially adversely affect our stock price and our ability to raise capital necessary to operate our business. In addition, we may be required to incur costs in improving our internal control system and hiring additional personnel.

The failure to integrate successfully the businesses of Tekmira and OnCore in the expected timeframe would adversely affect Tekmira’s future results following the completion of the merger.

Tekmira recently closed a merger transaction whereby OnCore became its wholly owned subsidiary.  The success of Tekmira will depend, in large part, on the ability of Tekmira to realize the anticipated benefits from this merger, including operating synergies, from combining the businesses of Tekmira and OnCore. To realize these anticipated benefits, Tekmira must successfully integrate the businesses of Tekmira and OnCore. This integration will be complex and time-consuming. Tekmira can offer no assurance that it realize the benefits anticipated to result from the merger.

Potential difficulties that may be encountered in the integration process include the following:
 
• complexities associated with managing the larger, combined business;
• integrating personnel from the two companies;
• potential unknown liabilities and unforeseen expenses, delays or regulatory conditions associated with the merger;
• performance shortfalls at one or both of the companies as a result of the diversion of management’s attention caused by completing the merger and integrating the companies’ operations and
• challenges related to the management and monitoring of new operations and associated increased costs and complexity.

Tekmira’s success will be dependent on its ability to maintain and renew relationships with pre-existing third party relationships. There can be no assurance that the business of Tekmira will be able to maintain pre-existing business relationships, or enter into or maintain new business relationships, on acceptable terms, if at all. The failure to maintain important pre-existing third party relationships could have a material adverse effect on the business, financial condition or results of operations of Tekmira.
 
Risks Related to Development, Clinical Testing and Regulatory Approval of Our Product Candidates
 
The manufacture and sale of human therapeutic products are governed by a variety of statutes and regulations. There can be no assurance that our product candidates will obtain regulatory approval.
 
To obtain marketing approval, U.S. and Canadian laws require:
 
 
·
controlled research and human clinical testing;
 
·
establishment of the safety and efficacy of the product for each use sought;
 
·
government review and approval of a submission containing manufacturing, pre-clinical and clinical data;
 
·
adherence to Good Manufacturing Practice Regulations during production and storage; and
 
·
control of marketing activities, including advertising and labelling

The product candidates we currently have under development will require significant development, pre-clinical trial and clinical testing and investment of significant funds before their commercialization.  Some of our product candidates, if approved, will require the completion of post-market studies. There can be no assurance that such products will be developed. The process of completing clinical testing and obtaining required approvals is likely to take a number of years and require the use of substantial resources. If we fail to obtain regulatory approvals, our operations will be adversely affected. Further, there can be no assurance that product candidates employing a new technology will be shown to be safe and effective in clinical trials or receive applicable regulatory approvals.
 
 
26

 
Other markets have regulations and restrictions similar to those in the U.S. and Canada. Investors should be aware of the risks, problems, delays, expenses and difficulties which we may encounter in view of the extensive regulatory environment which affects our business in any jurisdiction where we develop product candidates.
 
If testing of a particular product candidate does not yield successful results, then we will be unable to commercialize that product candidate.
 
We must demonstrate our product candidates’ safety and efficacy in humans through extensive clinical testing. Our research and development programs are at an early stage of development. We may experience numerous unforeseen events during, or as a result of, the testing process that could delay or prevent commercialization of any products, including the following:
 
 
·
decreased demand for our product candidates;
 
·
impairment of our business reputation;
 
·
withdrawal of clinical trial participants;
 
·
costs of related litigation;
 
·
substantial monetary awards to patients or other claimants;
 
·
loss of revenues; and
 
·
inability to commercialize our product candidates.
 
Although we currently have product liability insurance coverage for our clinical trials for expenses or losses, our insurance coverage is limited to $10 million per occurrence, and $10 million in the aggregate, and may not reimburse us or may not be sufficient to reimburse us for any or all expenses or losses we may suffer. Moreover, insurance coverage is becoming increasingly expensive and, in the future, we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to liability. We intend to expand our insurance coverage to include the sale of commercial products if we obtain marketing approval for our product candidates in development, but we may be unable to obtain commercially reasonable product liability insurance for any products approved for marketing. On occasion, large judgments have been awarded in class action lawsuits based on products that had unanticipated side effects. A successful product liability claim or series of claims brought against us could cause our stock price to fall and, if judgments exceed our insurance coverage, could decrease our cash and adversely affect our business.
 
The Animal Rule is a new and seldom-used approach to seeking approval of a new drug, and our TKM-Ebola program may not meet the requirements for this path to regulatory approval.
 
We plan to develop the TKM-Ebola therapeutic product candidate to treat Ebola virus using the “Animal Rule” regulatory mechanism. Pursuant to the Animal Rule, we must demonstrate efficacy in animal models and safety in humans. There is no guarantee that the FDA will agree to this approach for the development of TKM-Ebola, considering that no validated animal model has been established as predicting human outcomes in the prevention or treatment of the Ebola virus. The FDA may decide that our data are insufficient for approval and require additional pre-clinical, clinical, or other studies, or refuse to approve our products, or place restrictions on our ability to commercialize those products. Animal models represent, at best, a rough approximation of efficacy in humans, and, as such, countermeasures developed using animal models will be untested until their use in humans during an emergency.
 
Recently enacted and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our drug candidates and affect the prices we may obtain.
 
In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could, among other things, prevent or delay marketing approval of our drug candidates, restrict or regulate post approval activities and affect our ability to profitably sell any products for which we obtain marketing approval.
 
For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care Education Reconciliation Act, or collectively the Affordable Care Act, was enacted to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new transparency requirements for health care and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms. Although it is too early to determine the effect of the Affordable Care Act, the new law appears likely to continue the downward pressure on pharmaceutical pricing, especially under the Medicare program, and may also increase our regulatory burdens and operating costs.
 
Moreover, the recently enacted Drug Supply Chain Security Act imposes new obligations on manufacturers of pharmaceutical products related to product and tracking and tracing. Legislative and regulatory proposals have been made to expand post approval requirements and restrict sales and promotional activities for pharmaceutical products. We are not sure whether additional legislative changes will be enacted, or whether the current regulations, guidance or interpretations will be changed, or what the impact of such changes on our business, if any, may be.
 
 
27

 
Coverage and adequate reimbursement may not be available for our drug candidates, which could make it difficult for us to sell our products profitably.
 
Market acceptance and sales of any drug candidates that we develop, will depend in part on the extent to which reimbursement for these products and related treatments will be available from third party payors, including government health administration authorities and private health insurers. Third party payors decide which drugs they will pay for and establish reimbursement levels. Third party payors often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement policies. However, decisions regarding the extent of coverage and amount of reimbursement to be provided for each of our drug candidates will be made on a plan by plan basis. One payors determination to provide coverage for a product does not assure that other payors will also provide coverage, and adequate reimbursement, for the product. Additionally, a third party payors decision to provide coverage for a drug does not imply that an adequate reimbursement rate will be approved. Each plan determines whether or not it will provide coverage for a drug, what amount it will pay the manufacturer for the drug, and on what tier of its formulary the drug will be placed. The position of a drug on a formulary generally determines the copayment that a patient will need to make to obtain the drug and can strongly influence the adoption of a drug by patients and physicians. Patients who are prescribed treatments for their conditions and providers performing the prescribed services generally rely on third party payors to reimburse all or part of the associated healthcare costs. Patients are unlikely to use our products unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our products.
 
A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Third party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. We cannot be sure that coverage and reimbursement will be available for any product that we commercialize and, if reimbursement is available, what the level of reimbursement will be. Inadequate coverage and reimbursement may impact the demand for, or the price of, any product for which we obtain marketing approval. If coverage and adequate reimbursement is not available, or is available only to limited levels, we may not be able to successfully commercialize any drug candidates that we develop.

Additionally, there have been a number of legislative and regulatory proposals to change the healthcare system in the United States and in some foreign jurisdictions that could affect our ability to sell any future drugs profitably. These legislative and regulatory changes may negatively impact the reimbursement for any future drugs, following approval.

Risks Related to Patents, Licenses and Trade Secrets
 
Other companies or organizations may assert patent rights that prevent us from developing or commercializing our products.
 
RNA interference is a relatively new scientific field that has generated many different patent applications from organizations and individuals seeking to obtain patents in the field. These applications claim many different methods, compositions and processes relating to the discovery, development and commercialization of RNAi therapeutic products. Because the field is so new, very few of these patent applications have been fully processed by government patent offices around the world, and there is a great deal of uncertainty about which patents will be issued, when, to whom, and with what claims. It is likely that there could be litigation and other proceedings, such as interference and opposition proceedings in various patent offices, relating to patent rights in RNAi.

In addition, there are many issued and pending patents that claim aspects of RNAi trigger chemistry technology that we may need to apply to our product candidates. There are also many issued patents that claim genes or portions of genes that may be relevant for RNAi trigger drug products we wish to develop. Thus, it is possible that one or more organizations will hold patent rights to which we will need a license. If those organizations refuse to grant us a license to such patent rights on reasonable terms, we will not be able to market products or perform research and development or other activities covered by these patents.
 
Our patents and patent applications may be challenged and may be found to be invalid, which could adversely affect our business.
 
Certain Canadian, U.S. and international patents and patent applications we own involve complex legal and factual questions for which important legal principles are largely unresolved. For example, no consistent policy has emerged for the breadth of biotechnology patent claims that are granted by the U.S. Patent and Trademark Office or enforced by the U.S. federal courts. In addition, the coverage claimed in a patent application can be significantly reduced before a patent is issued. Also, we face the following intellectual property risks:
 
 
·
some or all patent applications may not result in the issuance of a patent;
 
·
patents issued may not provide the holder with any competitive advantages;
 
·
patents could be challenged by third parties;
 
·
the patents of others, including Alnylam, could impede our ability to do business;
 
·
competitors may find ways to design around our patents; and
 
·
competitors could independently develop products which duplicate our products.
 
A number of industry competitors and institutions have developed technologies, filed patent applications or received patents on various technologies that may be related to or affect our business. Some of these technologies, applications or patents may conflict with our technologies or patent applications. Such conflict could limit the scope of the patents, if any, that we may be able to obtain or result in the denial of our patent applications. In addition, if patents that cover our activities are issued to other companies, there can be no assurance that we would be able to obtain licenses to these patents at a reasonable cost or be able to develop or obtain alternative technology. If we do not obtain such licenses, we could encounter delays in the introduction of products, or could find that the development, manufacture or sale of products requiring such licenses is prohibited. In addition, we could incur substantial costs in defending patent infringement suits brought against us or in filing suits against others to have such patents declared invalid. As publication of discoveries in the scientific or patent literature often lags behind actual discoveries, we cannot be certain we or any licensor was the first creator of inventions covered by pending patent applications or that we or such licensor was the first to file patent applications for such inventions. Any future proceedings could result in substantial costs, even if the eventual outcomes are favorable. There can be no assurance that our patents, if issued, will be held valid or enforceable by a court or that a competitor’s technology or product would be found to infringe such patents.
 
 
28

 
Our business depends, in part, on our ability to use RNAi technology that we have licensed or will in the future license from third parties, including Alnylam, and, if these licenses were terminated or if we were unable to license additional technology we may need in the future, our business will be adversely affected.
 
We currently hold licenses for certain technologies that are or may be applicable to our current and subsequent product candidates. These include a license to patents held or applied for by Alnylam and a license to UNA technology from Arcturus Therapeutics. The licenses are subject to termination in the event of a breach by us of the license, if we fail to cure the breach following notice and the passage of a cure period. The UBC license, which is sublicensed to Alnylam, is subject to termination with respect to one or more particular patents if we and Alnylam were to cease patent prosecution or maintenance activities with respect to such patent(s), or in the event of a breach by us of the license, if we fail to cure the breach following notice and the passage of a cure period. There can be no assurance that these licenses will not be terminated. We may need to acquire additional licenses in the future to technologies developed by others, including Alnylam. For example, Alnylam has granted us a worldwide license for the discovery, development and commercialization of RNAi products directed to thirteen gene targets (three exclusive and ten non-exclusive licenses). Licenses for the five non-exclusive targets and one exclusive target have already been granted. We have rights to select the gene targets for up to two more exclusive licenses and five more nonexclusive licenses from Alnylam, which would be made available to us only if they have not been previously selected by Alnylam or one of its other partners. This will limit the targets available for selection by us, and we may never be able to select gene targets or may be required to make our selection from gene targets that have minimal commercial potential. Furthermore, future license agreements may require us to make substantial milestone payments. We will also be obligated to make royalty payments on the sales, if any, of products resulting from licensed RNAi technology. For some of our licensed RNAi technology, we are responsible for the costs of filing and prosecuting patent applications. The termination of a license or the inability to license future technologies on acceptable terms may adversely affect our ability to develop or sell our products.
 
Our business depends, in part, on our ability to use the technology that we have licensed or will in the future license from third parties, including Blumberg, NeuroVive and Cytos, and, if these licenses were terminated or if we were unable to license additional technology we may need in the future, our business will be adversely affected.
 
Through our wholly owned subsidiary, OnCore, we have licensed certain of our intellectual property from Blumberg and NeuroVive and Cytos. Our current technology licenses are critical to our business and we expect to enter into additional licenses in the future.  If we fail to comply with our obligations under these agreements or any future license agreements, we are subject to a bankruptcy, or if we grant a sublicense in the future and our sublicense does not comply with our obligations under these agreements or becomes subject to a bankruptcy, the licensor may have the right to terminate the license, in which event we would not be able to develop or market products covered by the license or may face other penalties under the agreements, which would have a materially adverse effect on our business. In addition, applicable laws involving bankruptcy or similar proceeding by licensors in some jurisdictions outside the United States may provide the trustee or receiver in such proceeding with the right to set aside or otherwise terminate or seek to modify the license. Any termination of these agreements or reduction or elimination of our rights under these agreements may result in our having to negotiate new or amended agreements with less favorable terms, or cause us to lose our rights under these agreements, including our rights to important intellectual property and technologies that form the basis of our technology, which may then be in licensed by one or more of our competitors.

We may incur substantial costs as a result of litigation or other proceedings relating to patent and other intellectual property rights which could have a material adverse effect on our business, financial condition and results of operations and could cause the market value of our Common Shares to decline.

There has been significant litigation in the biotechnology industry over contractual obligations, patents and other proprietary rights, and we may become involved in various types of litigation that arise from time to time. Involvement in litigation could consume a substantial portion of our resources, regardless of the outcome of the litigation. Counterparties in litigation may be better able to sustain the costs of litigation because they have substantially greater resources. If claims against us are successful, in addition to any potential liability for damages, we could be required to obtain a license, grant cross-licenses, and pay substantial milestones or royalties in order to continue to develop, manufacture or market the affected products. Involvement and continuation of involvement in litigation may result in significant and unsustainable expense, and divert management’s attention from ongoing business concerns and interfere with our normal operations. Litigation is also inherently uncertain with respect to the time and expenses associated therewith, and involves risks and uncertainties in the litigation process itself, such as discovery of new evidence or acceptance of unanticipated or novel legal theories, changes in interpretation of the law due to decisions in other cases, the inherent difficulty in predicting the decisions of judges and juries and the possibility of appeals. Ultimately we could be prevented from commercializing a product or be forced to cease some aspect of our business operations as a result of claims of patent infringement or violation of other intellectual property rights and the costs associated with litigation, which could have a material adverse effect on our business, financial condition, and operating results and could cause the market value of our Common Shares to decline.
 
 
29

 
Confidentiality agreements with employees and others, including collaborators, may not adequately prevent disclosure of trade secrets and other proprietary information.
 
Much of our know-how and technology may constitute trade secrets. There can be no assurance, however, that we will be able to meaningfully protect our trade secrets. In order to protect our proprietary technology and processes, we rely in part on confidentiality agreements with our collaborators, employees, vendors, consultants, outside scientific collaborators and sponsored researchers, and other advisors. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. In addition, others may independently discover trade secrets and proprietary information, and in such cases we could not assert any trade secret rights against such party. Costly and time consuming litigation could continue to be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could adversely affect our competitive business position.
 
Risks Related to Competition
 
The pharmaceutical market is intensely competitive. If we are unable to compete effectively with existing drugs, new treatment methods and new technologies, we may be unable to successfully commercialize any product candidates that we develop.
 
The pharmaceutical market is intensely competitive and rapidly changing. Many large pharmaceutical and biotechnology companies, academic institutions, governmental agencies and other public and private research organizations are pursuing the development of novel drugs for the same diseases that we are targeting or expect to target. Many of our competitors have:
 
 
·
much greater financial, technical and human resources than we have at every stage of the discovery, development, manufacture and commercialization process;
 
·
more extensive experience in pre-clinical testing, conducting clinical trials, obtaining regulatory approvals, and in manufacturing, marketing and selling pharmaceutical products;
 
·
product candidates that are based on previously tested or accepted technologies;
 
·
products that have been approved or are in late stages of development; and

collaborative arrangements in our target markets with leading companies and research institutions.
 
We will face intense competition from products that have already been approved and accepted by the medical community for the treatment of the conditions for which we are currently developing products. We also expect to face competition from new products that enter the market. We believe a significant number of products are currently under development, and may become commercially available in the future, for the treatment of conditions for which we may try to develop products. These products, or other of our competitors’ products, may be more effective, safer, less expensive or marketed and sold more effectively, than any products we develop.
 
We are aware of several companies that are working to develop drugs that would compete against our drug candidates for HBV treatment. As a significant unmet medical need exists for HBV, there are several large and small pharmaceutical companies focused on delivering therapeutics for treatment of HBV. Further, it is likely that additional drugs will become available in the future for the treatment of HBV. We will face competition from other drugs currently approved or that will be approved in the future for the treatment of chronic hepatitis B.
  
There are a large number of companies that are developing new agents for use in cancer therapy including RNAi therapeutics, and there are other companies developing small molecule drugs designed to inhibit the PLK1 target, including Onconova Therapeutics and Millennium/Takeda. These agents may be competitive with our product candidate TKM-PLK1.

We anticipate significant competition in the HBV market with several early phase product candidates announced. In addition, there are organizations working on treatments for Ebola virus disease and other hemorrhagic fever viruses. We will also face competition for other product candidates that we expect to develop in the future.
 
If we successfully develop product candidates, and obtain approval for them, we will face competition based on many different factors, including the following:
 
 
·
safety and effectiveness of our products
 
·
ease with which our products can be administered and the extent to which patients and physicians accept new routes of administration;
 
·
timing and scope of regulatory approvals for these products;
 
·
availability and cost of manufacturing, marketing and sales capabilities;
 
·
price;
 
·
reimbursement coverage; and
 
·
patent position.

Our competitors may develop or commercialize products with significant advantages over any products we develop based on any of the factors listed above or on other factors. Our competitors may therefore be more successful in commercializing their products than we are which could adversely affect our competitive position and business. Competitive products may make any products we develop obsolete or uncompetitive before we can recover the expenses of developing and commercializing our product candidates. Such competitors could also recruit our employees, which could negatively impact our level of expertise and the ability to execute on our business plan. Furthermore, we also face competition from existing and new treatment methods that reduce or eliminate the need for drugs, such as the use of advanced medical devices. The development of new medical devices or other treatment methods for the diseases we are targeting and may target could make our product candidates non-competitive, obsolete or uneconomical.
 
We face competition from other companies that are working to develop novel products using technology similar to ours. If these companies develop products more rapidly than we do or their technologies, including delivery technologies, are more effective than ours, then our ability to successfully commercialize products will be adversely affected.

In addition to the competition we face from competing products in general, we also face competition from other companies working to develop novel products using technology that competes more directly with our own. There are multiple companies working in the field of RNAi, including major pharmaceutical companies such as Novartis International AG, Takeda Pharmaceutical Company Limited, and Merck, and biotechnology companies such as Alnylam, Quark Pharmaceuticals, Inc., Silence Therapeutics plc, Arrowhead Research Corporation and its subsidiary, Calando Pharmaceuticals, Inc., Marina, RXi Pharmaceuticals Corporation, Dicerna Pharmaceuticals, Inc., Sylentis S.A., Santaris Pharma A/S, and Benitec Ltd., among others. Any of these companies may develop its RNAi technology more rapidly and more effectively than we do or may develop products against the same target or disease indication that we are pursuing.

We also compete with companies working to develop antisense-based drugs, such as Isis Pharmaceuticals, Inc. and Sarepta. Like RNAi therapeutic products, antisense drugs target messenger RNAs, or mRNAs, in order to suppress the activity of specific genes. Isis is the developer of a currently approved antisense drug and has several antisense product candidates in clinical trials. Isis has also licensed its antisense technology to a number of other companies that are developing antisense-based drugs. The development of antisense drugs is more advanced than that of RNAi therapeutic products, and antisense technology may become the preferred technology for products that target mRNAs to silence specific genes.

In addition to competition with respect to RNAi and with respect to specific products, we face substantial competition to discover and develop safe and effective means to deliver RNAi triggers to the relevant cell and tissue types. Our competitors may develop safer and more effective means to deliver RNAi triggers to the relevant cell and tissue types than our existing lipid nanoparticle delivery technology, and our ability to successfully commercialize our products would be adversely affected. In addition, substantial resources are being expended by third parties in the effort to discover and develop alternative means of delivering RNAi triggers into the relevant cell and tissue types, both in academic laboratories and in the corporate sector. Some of our competitors have substantially greater resources than we do, and if our competitors are able to negotiate exclusive access to those delivery solutions developed by third parties, we may be unable to successfully commercialize our product candidates.

We face significant competition from other biotechnology and pharmaceutical companies targeting HBV.
 
As a significant unmet medical need exists for HBV, there are several large and small pharmaceutical companies focused on delivering therapeutics for treatment of HBV. Further, it is likely that additional drugs will become available in the future for the treatment of HBV.
 
We are aware of several companies that are working to develop drugs that would compete against our drug candidates for HBV treatment. Many of our existing or potential competitors have substantially greater financial, technical and human resources than we do and significantly greater experience in the discovery and development of drug candidates, as well as in obtaining regulatory approvals of those drug candidates in the United States and in foreign countries. Our current and potential future competitors also have significantly more experience commercializing drugs that have been approved for marketing. Mergers and acquisitions in the pharmaceutical and biotechnology industries could result in even more resources being concentrated among a small number of our competitors.
 
Competition may increase further as a result of advances in the commercial applicability of technologies and greater availability of capital for investment in these industries. Our competitors may succeed in developing, acquiring or licensing, on an exclusive basis, drug candidates that are more effective or less costly than any drug candidate that we may develop.
 
We will face competition from other drugs currently approved or that will be approved in the future for the treatment of HBV. Therefore, our ability to compete successfully will depend largely on our ability to:
 
 
discover, develop and commercialize drugs that are superior to other products in the market;
 
 
demonstrate through our clinical trials that our drug candidates are differentiated from existing and future therapies;
 
 
attract qualified scientific, product development and commercial personnel;
 
 
obtain patent or other proprietary protection for our drugs and technologies;
 
 
31

 
 
obtain required regulatory approvals;
 
 
successfully collaborate with pharmaceutical companies in the discovery, development and commercialization of new drugs; and
 
 
negotiate competitive pricing and reimbursement with third party payors.
 
The availability of our competitors’ products could limit the demand, and the price we are able to charge, for any drug candidate we develop. The inability to compete with existing or subsequently introduced drug candidates would have a material adverse impact on our business, financial condition and prospects.
 
Established pharmaceutical companies may invest heavily to accelerate discovery and development of novel compounds or to in license novel compounds that could make our drug candidates less competitive. In addition, any new product that competes with an approved product must demonstrate compelling advantages in efficacy, convenience, tolerability and safety in order to overcome price competition and to be commercially successful. Accordingly, our competitors may succeed in obtaining patent protection, discovering, developing or receiving FDA approval for or commercializing medicines before we do, which would have a material adverse impact on our business.

Risks Related to the Ownership of our Common Shares

If our stock price fluctuates, our investors could incur substantial losses.

The market price of our Common Shares may fluctuate significantly in response to factors that are beyond our control. The stock market in general has recently experienced extreme price and volume fluctuations. The market prices of securities of pharmaceutical and biotechnology companies have been extremely volatile, and have experienced fluctuations that often have been unrelated or disproportionate to the operating performance of these companies. These broad market fluctuations could result in extreme fluctuations in the price of our Common Shares, which could cause our investors to incur substantial losses.

There is no assurance that an active trading market in our Common Shares will be sustained.

Our Common Shares are listed for trading on the NASDAQ exchange. However, there can be no assurances that an active trading market in our Common Shares on these stock exchanges will be sustained.

We are incorporated in Canada and the majority of our assets, and some of our officers reside outside the United States, with the result that it may be difficult for investors to enforce any judgments obtained against us or some of our officers.

Tekmira, and some of its subsidiaries, are incorporated under the laws of the Province of British Columbia and the majority of Tekmira’s assets are located outside the United States. While we have appointed National Registered Agents, Inc. as our agent for service of process to effect service of process within the United States upon us, it may not be possible for you to enforce against us or those persons in the United States, judgments obtained in U.S. courts based upon the civil liability provisions of the U.S. federal securities laws or other laws of the United States. In addition, there is doubt as to whether original action could be brought in Canada against us or our directors or officers based solely upon U.S. federal or state securities laws and as to the enforceability in Canadian courts of judgments of U.S. courts obtained in actions based upon the civil liability provisions of U.S. federal or state securities laws.

If we are deemed to be a “passive foreign investment company” for the current or any future taxable year, investors who are subject to United States federal taxation would likely suffer materially adverse U.S. federal income tax consequences.

We generally will be a “passive foreign investment company” under the meaning of Section 1297 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), (a “PFIC”) if (a) 75% or more of our gross income is “passive income” (generally, dividends, interest, rents, royalties, and gains from the disposition of assets producing passive income) in any taxable year, or (b) if at least 50% or more of the quarterly average value of our assets produce, or are held for the production of, passive income in any taxable year. A shareholder who is a U.S. person (as such term is defined under applicable U.S. legislation) should be aware that we believe that we were a PFIC during one or more prior taxable years.  We have not yet made a determination as to whether we were a PFIC in respect of our taxable year ended December 31, 2014.  If we are a PFIC for any taxable year during which a U.S. person holds our Common Shares, it would likely result in materially adverse U.S. federal income tax consequences for such U.S. person, including, but not limited to, any gain from the sale of our Common Shares would be taxed as ordinary income, as opposed to capital gain, and such gain and certain distributions on our Common Shares would be subject to an interest charge, except in certain circumstances. It may be possible for U.S. persons to fully or partially mitigate such tax consequences by making a “qualifying electing fund election,” as defined in the Code (a “QEF Election”), but there is no assurance that we will provide such persons with the information that we are required to provide to them in order to assist them in making a QEF Election.  In addition, U.S. persons that hold Common Shares issuable upon exercise of warrants are generally not eligible to make certain elections available under the Code that are intended to mitigate the adverse tax consequences of PFIC rules with respect to such warrant shares unless such holders also elect to make a deemed taxable sale of their warrant shares. The PFIC rules are extremely complex.

Our articles and certain Canadian laws could delay or deter a change of control.

Our preferred shares are available for issuance from time to time at the discretion of our board of directors, without shareholder approval. Our articles allow our board, without shareholder approval, to determine the special rights to be attached to our preferred shares, and such rights may be superior to those of our Common Shares.

In addition, limitations on the ability to acquire and hold our Common Shares may be imposed by the Competition Act in Canada. This legislation permits the Commissioner of Competition of Canada to review any acquisition of a significant interest in us. This legislation grants the Commissioner jurisdiction to challenge such an acquisition before the Canadian Competition Tribunal if the Commissioner believes that it would, or would be likely to, result in a substantial lessening or prevention of competition in any market in Canada. The Investment Canada Act subjects an acquisition of control of a company by a non-Canadian to government review if the value of our assets, as calculated pursuant to the legislation, exceeds a threshold amount. A reviewable acquisition may not proceed unless the relevant minister is satisfied that the investment is likely to result in a net benefit to Canada. Any of the foregoing could prevent or delay a change of control and may deprive or limit strategic opportunities for our shareholders to sell their shares.

The exercise of all or any number of outstanding stock options, the award of any additional options, bonus shares or other stock-based awards or any issuance of shares to raise funds or acquire a business may dilute your Common Shares.

We have in the past and may in the future grant to some or all of our directors, officers and employees options to purchase our Common Shares and other stock-based awards as non-cash incentives to those persons. The issuance of any equity securities could, and the issuance of any additional shares will, cause our existing shareholders to experience dilution of their ownership interests.

Any additional issuance of shares or a decision to acquire other businesses through the sale of equity securities may dilute our investors’ interests, and investors may suffer dilution in their net book value per share depending on the price at which such securities are sold. Such issuance may cause a reduction in the proportionate ownership and voting power of all other shareholders. The dilution may result in a decline in the price of our Common Shares or a change in control.

We do not expect to pay dividends for the foreseeable future.

We have not paid any cash dividends to date and we do not intend to declare dividends for the foreseeable future, as we anticipate that we will reinvest future earnings, if any, in the development and growth of our business. Therefore, investors will not receive any funds unless they sell their Common Shares, and shareholders may be unable to sell their shares on favorable terms or at all. We cannot assure you of a positive return on investment or that you will not lose the entire amount of your investment in our Common Shares. Prospective investors seeking or needing dividend income or liquidity should not purchase our Common Shares.

The value of our securities, including our Common Shares, might be affected by matters not related to our operating performance and could subject us to securities litigation.
 
The value of our Common Shares may be reduced for a number of reasons, many of which are outside our control, including:
 
 
·
general economic and political conditions in Canada, the United States and globally;
 
·
governmental regulation of the health care and pharmaceutical industries;
 
·
failure to achieve desired drug discovery outcomes by us or our collaborators;
 
·
failure to obtain industry partner and other third party consents and approvals, when required;
 
·
stock market volatility and market valuations;
 
·
competition for, among other things, capital, drug targets and skilled personnel;
 
·
the need to obtain required approvals from regulatory authorities;
 
·
revenue and operating results failing to meet expectations in any particular period;
 
·
investor perception of the health care and pharmaceutical industries;
 
·
limited trading volume of our Common Shares;
 
·
announcements relating to our business or the businesses of our competitors; and
 
·
our ability or inability to raise additional funds.
 
The concentration of the common shares ownership with insiders will likely limit the ability of the other shareholders to influence corporate matters.

As of March 9, 2015, executive officers, directors, five percent or greater shareholders, and their respective affiliated entities of the Tekmira beneficially own, in the aggregate, approximately 44% of Tekmira’s outstanding common shares. As a result, these shareholders, acting together, have significant influence over most matters that require approval by Tekmira’s shareholders, including the election of directors and approval of significant corporate transactions. Corporate actions might be taken even if other shareholders oppose them. This concentration of ownership might also have the effect of delaying or preventing a corporate transaction that other shareholders may view as beneficial.
 
 
33

 
If securities analysts do not publish research or reports about the business of Tekmira, or if they publish negative evaluations, the price of Tekmira’s Common Shares could decline.

The trading market for the Tekmira’s Common Shares may be impacted by the availability or lack of research and reports that third-party industry or financial analysts publish about Tekmira. There are many large, publicly traded companies active in the biopharmaceutical industry, which may mean it will be less likely that Tekmira receives widespread analyst coverage. Furthermore, if one or more of the analysts who do cover Tekmira downgrade its stock, its stock price would likely decline. If Tekmira does not receive adequate coverage by reputable analysts that have an understanding of Tekmira’s business and industry, it could fail to achieve visibility in the market, which in turn could cause its stock price to decline.

Risk Factors Relating to Assets Acquired as a result of the Merger with OnCore
 
We are required to make deferred payments in connection with OnCore’s prior acquisition of Enantigen, and its failure to make these payments may adversely affect Tekmira’s ability to progress certain of its drug development programs.

In connection with OnCore’s acquisition of Enantigen, OnCore paid $2.0 million in cash to Enantigen’s selling stockholders in October 2014 and an additional $1.0 million in cash in December 2014. We are obligated to pay an additional $2.0 million in cash by March 31, 2015. If we do not pay this amount as required, we would be required to return all shares of Enantigen to its former stockholders, which would mean that we would lose our rights to certain HBV surface antigen secretion inhibitor and capsid assembly inhibitor programs.

OnCore has licensed critical portions of its intellectual property from Blumberg, Drexel and NeuroVive, and is subject to significant obligations under those license agreements.

The rights OnCore holds under its license agreements with Blumberg, Drexel and NeuroVive are important to its business. The OnCore discovery and development platform is built, in part, around patents exclusively in licensed from these parties. For example, the elimination of cccDNA is the most critical element in our combination strategy to cure HBV, and the cccDNA formation inhibitor program is in licensed from Blumberg and Drexel.

OnCore has licenses with Blumberg and Drexel, both directly and through its acquisition of Enantigen, that grant it the exclusive (except in some cases as to know how that is not unique or specific to the licensed products or compound series, which are non-exclusive and subject to retained rights for non-commercial research use), worldwide license to make, have made, use, import, offer for sale and sell products incorporating one or more licensed compounds, which include cccDNA inhibitors, capsid assembly inhibitors, inhibitors of secretion of HBV antigens and hepatocellular carcinoma inhibitors, either for general use in humans or for use in the field of HBV research, diagnosis and treatment. OnCore’s license with NeuroVive grants OnCore the exclusive, worldwide license under patents and know how controlled by NeuroVive to develop, manufacture and commercialize for the treatment of HBV, oral dosage form products, or licensed products, that incorporate sanglifehrin based cyclophilin inhibitors, including OnCore’s drug candidate OCB-030.  OnCore’s license with Cytos grants OnCore the exclusive, worldwide, sub licensable (subject to certain restrictions with respect to licensed viral infections other than hepatitis) license, under patents and know-how controlled by Cytos, to research, develop, manufacture and commercialize, for the diagnosis, treatment or prevention of hepatitis viruses in humans, licensed products that incorporate Q beta-derived virus-like particles that are filled with TLR9, TLR7 or RIG-I agonists.

Under OnCore’s agreements with Blumberg, Drexel, NeuroVive and Cytos, OnCore is subject to significant obligations, including diligence obligations with respect to development and commercialization activities, payment obligations upon achievement of certain milestones and royalties on product sales, as well as other material obligations. Under OnCore’s direct agreement with Blumberg and Drexel, OnCore agreed to pay up to $3.5 million in development and regulatory milestones per licensed compound series, up to $92.5 million in sales performance milestones per licensed product, and royalties in the mid-single digits in connection with the sale of licensed products. Under each of the three license agreements that OnCore’s subsidiary Enantigen has with Blumberg and Drexel, Enantigen is obligated to pay up to $500,000 in development and regulatory milestones per licensed product and royalties in the low single digits in connection with the sale of licensed products. Under OnCore’s agreement with NeuroVive, OnCore agreed to pay up to $47.0 million in clinical development and regulatory milestones per indication, up to $102.5 million in sales performance milestones per licensed product and indication, and tiered royalties in the mid-single to low double digits in connection with the sale of licensed products. Under OnCore’s agreement with Cytos, OnCore agreed to pay up to $67 million upon the achievement of specified development and regulatory milestones for hepatitis and each additional licensed viral infection, in each case for each of the six licensed compound series, up to $110 million upon the achievement of specified sales performance milestones, and tiered royalty payments at a royalty rate in the high-single to low double digits, based upon net sales of licensed products. If these payments become due under the terms of the agreements, OnCore may not have sufficient funds available to meet its obligations and we may be negatively affected.

 
34

 
If there is any conflict, dispute, disagreement or issue of non-performance between OnCore and Blumberg, Drexel, NeuroVive or Cytos regarding OnCore’s rights or obligations under these license agreements, including any conflict, dispute or disagreement arising from OnCore failure to satisfy diligence or payment obligations under such agreements, Blumberg and Drexel or NeuroVive or Cytos, as applicable, may have a right to terminate the license. The loss of any of these license agreements could materially and adversely affect OnCore’s ability to use intellectual property that is critical to our drug discovery and development efforts, as well as its ability to enter into future collaboration, licensing and/or marketing agreements for one or more affected drug candidates or development programs.

OnCore relies on and will incur additional expense in connection with its research collaboration with Blumberg.

In October 2014, OnCore entered into an agreement with Blumberg under which it will provide annual funding for a three year period in the amount of $1.0 million per year and which is renewable for an additional three year period at our option, for Blumberg to conduct research projects in HBV and liver cancer pursuant to a research plan to be agreed upon by the parties. In exchange, OnCore has the right to obtain an exclusive, royalty bearing, worldwide license to intellectual property generated by Blumberg in the course of the funded research and OnCore believes that Blumberg’s HBV research platform will continue to be a source of potentially novel hepatitis B targets, drug candidates, assays and other HBV specific technologies. As a result, OnCore is dependent, in part, upon the success of Blumberg in performing its responsibilities under this research collaboration. Blumberg may not cooperate with OnCore or perform its obligations under the agreement. OnCore cannot control the amount and timing of Blumberg’s resources that will be devoted to research and development activities related to our research collaboration. Further, development costs associated with OnCore’s research projects may be difficult to anticipate and exceed our expectations. If funding is unable to continue to financially support the collaboration, if OnCore does not obtain exclusive licenses from Blumberg to the resulting intellectual property, or if OnCore fails to comply with its obligations under those license agreements, its development efforts may be materially harmed.

Some of OnCore’s licensors have retained rights to develop and commercialize certain of its drug candidates to treat diseases other than HBV and, as a result, its development and commercialization efforts may be negatively affected.

OnCore’s license agreements provide OnCore with the rights to develop and commercialize our drug candidates for HBV; however, some of OnCore’s licensors have retained rights to develop and commercialize certain of its drug candidates to treat diseases other than HBV, and to license those rights to other third parties. For example, NeuroVive has retained rights to the development of sanglifehrin based cyclophilin inhibitors, including those having the same active ingredient as OCB-030, and Cytos has retained all rights with respect to development of the licensed products for influenza, all non-viral infections and certain viral infections other than hepatitis.

NeuroVive is currently performing preclinical studies on an intravenous formulation of one of these drug candidates with the intention of initiating clinical trials in cardiovascular disease and central nervous system conditions. Because NeuroVive’s drug candidate has the same active ingredient as OCB-030, OnCore’s ability to successfully develop and commercialize OCB-030 could be negatively affected by data, including any adverse events, arising from NeuroVive’s clinical trials. If OnCore obtains regulatory approval for OCB-030 or its TLR9 agonist for HBV and NeuroVive or Cytos, as the case may be, obtains regulatory approval for a drug candidate that has the same active ingredient as OCB-030 or our TLR9 agonist for another indication, and if each is available outside of a combination therapy, physicians may prescribe the NeuroVive or Cytos drug, instead of OnCore’s drug, to patients with HBV if, for example, the cost of the NeuroVive or Cytos drug is less than our drug. In this case, OnCore would not be receiving any payments on the account of such sales and our revenue would be adversely affected.

Properties
 
Our head office and principal place of business is located at 100-8900 Glenlyon Parkway, Burnaby, British Columbia, Canada, V5J 5J8. The Company leases a 51,000 square foot facility. On June 23, 2014, we signed a renewal agreement to the operating lease for its laboratory and office premises. The renewal is effective August 1, 2014 and expires July 31, 2019, but we have the option to extend the lease to 2024, 2029, and 2034. We believe that the total space available to us under our current lease will meet our needs for the foreseeable future and that additional space would be available to us on commercially reasonable terms if required.
 
Through our wholly owned subsidiary, OnCore, we have approximately 2,600 square feet of leased office space at 3805 Old Easton Road, Doylestown, PA 18902.
 
Item 3.
Legal Proceedings
 
We are involved with various legal matters arising in the ordinary course of business. We make provisions for liabilities when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Such provisions are reviewed at least quarterly and adjusted to reflect the impact of any settlement negotiations, judicial and administrative rulings, advice of legal counsel, and other information and events pertaining to a particular case. Litigation is inherently unpredictable. Although the ultimate resolution of these various matters cannot be determined at this time, we do not believe that such matters, individually or in the aggregate, will have a material adverse effect on our consolidated results of operations, cash flows, or financial condition.

Alnylam Pharmaceuticals Inc. (“Alnylam”)
 
On June 21, 2013, we transferred manufacturing process technology to Ascletis Pharmaceuticals (Hangzhou) Co., Ltd. (“Ascletis”) to enable them to produce ALN-VSP, a product candidate licensed to them by Alnylam. We believe that under a licensing agreement with Alnylam, the technology transfer to Ascletis triggers a $5 million milestone obligation from Alnylam to Tekmira. However, Alnylam has demanded a declaration that we have not yet met our milestone obligations. We dispute Alnylam’s position. To remedy this dispute, the parties have commenced arbitration proceedings, as provided for under the agreement.  In addition to seeking a declaration that we have met our obligations under the agreement, we have also stated a claim for breach of contract, breach of the implied covenant of good faith and fair dealing, and fraud.  The hearing date for this arbitration is currently set for the second week in May, 2015. 

University of British Columbia (“UBC”)
 
Certain early work on lipid nanoparticle delivery systems and related inventions was undertaken at the University of British Columbia (UBC). These inventions are licensed to us by UBC under a license agreement, initially entered in 1998 as amended in 2001, 2006 and 2007. We have granted sublicenses under the UBC license to Alnylam as well as to Talon.  Alnylam has in turn sublicensed back to us under the licensed UBC patents for discovery, development and commercialization of RNAi products. In mid-2009, we and our subsidiary Protiva entered into a supplemental agreement with UBC, Alnylam and AlCana Technologies, Inc., in relation to a separate research collaboration to be conducted among UBC, Alnylam and AlCana to which we have license rights. The settlement agreement signed in late 2012 to resolve the litigation among Alnylam, AlCana, Tekmira and Protiva provided for the effective termination of all obligations under such supplemental agreement as between and among all litigants.
 
On November 10, 2014, the University of British Columbia filed a demand for arbitration against Tekmira Pharmaceuticals Corp., BCICAC File No.: DCA-1623.  We received UBC’s Statement of Claims on January 16, 2015.  In its Statement of Claims, UBC alleges that it is entitled to $3.5 million in allegedly unpaid royalties based on publicly available information, and an unspecified amount based on non-public information.  UBC also seeks interest and costs, including legal fees. We dispute UBC’s allegation.  No dates have been scheduled for this arbitration.

Item 7.
Management’s Discussion and Analysis of Financial Condition and Results of Operations
 
 
Following our recent business combination with OnCore Biopharma Inc. (“OnCore”) we intend to focus our efforts on discovering, developing and commercializing a cure for patients suffering from chronic HBV infection, a disease of the liver caused by hepatitis B. Our strategy incorporates our heritage and expertise in RNAi combined with the newly acquired assets and expertise through the OnCore merger.

We believe that, as a result of the merger, Tekmira will be well positioned to capitalize on the HBV global market opportunity. Our current HBV pipeline consists of 9 drugs and drug candidates, with eight unique mechanisms of action. Our unique strategy is to target the three pillars we believe are necessary to deliver an HBV cure, including: (i)  suppressing HBV viral replication, (ii) restoring host response by suppressing HBsAg or activating/stimulating the host immune system directed at HBV and (iii) eliminating covalently closed circular DNA (cccDNA), the reservoir of viral genomic material. We believe that our chances for success in HBV are increased, and risk is mitigated, by having a portfolio of assets targeting these three strategies. Most importantly, we believe combination therapies are the key to HBV treatment and a potential cure. We believe that clinical development can be accelerated when multiple components of a combination therapy regimen are controlled by the same company and therefore we have retained exclusive worldwide development and commercialization rights to all of our drug candidates and programs in HBV.

Tekmira is a biopharmaceutical company that since inception has focused on developing and advancing novel RNA interference therapeutics, as well as pursuing partnering opportunities for its leading lipid nanoparticle (LNP) delivery technology. RNAi has the potential to generate a broad new class of therapeutics that take advantage of the body’s own natural processes to silence genes – or more specifically to eliminate specific gene-products from the cell. With this ability to eliminate disease-causing proteins from cells, RNAi products represent opportunities for therapeutic interventions that have not been achievable with conventional drugs.

Delivery technology is crucial in order to protect RNAi drugs in the bloodstream following administration, allow efficient delivery to the target cells, and facilitate cellular uptake and release into the cytoplasm of the cell. By encapsulating the RNAi trigger molecules in lipid particles, Tekmira’s propriety LNP technology enables efficient delivery and uptake into target cells. Tekmira’s LNP technology represents the most widely adopted delivery technology in RNAi. To date, it has enabled eight clinical trials and been administered to well over 250 patients. Furthermore, recent results demonstrate that multi-dosing with LNP has been well-tolerated with treatments out to one year.

LNP can also enable a wide variety of nucleic acid triggers, including messenger RNA. As such, we continue to seek new product development and partnering opportunities based on our industry-leading delivery expertise. 
 
Our Product Candidates
 
As a result of our merger with OnCore our pipeline of assets has expanded beyond therapeutics being developed with RNAi technology. In HBV, we have what we believe is an industry-leading pipeline focused on curing HBV. Our belief is that to achieve an HBV cure, a combination of products that affect the main drivers of HBV need to be utilized. Specifically, this means that to be successful, we believe we need to have products that address HBV persistence — in antiviral replication, immune reactivation and the presence of cccDNA.

 
39

 
Once multiple compounds within the portfolio with sufficient anti HBV activity have been identified, we intend, subject to discussions with regulatory authorities, to conduct a rolling Phase II clinical program. These studies will likely evaluate combinations of two or more drug candidates in small cohorts of patients with chronic HBV infection to identify active combinations and those that do not have sufficient antiviral activity. We also plan to evaluate different treatment durations to determine the optimal duration for a finite duration therapy. We expect to use these results to adaptively design additional treatment regimens for the next cohorts. We plan to continue this iterative process until we select combination therapy regimens and treatment durations to conduct Phase III clinical trials intended to ultimately support regulatory filings for marketing approval.

We intend to continue to expand our HBV pipeline through internal development, acquisitions and in-licenses. We believe that a major engine for internal innovation is the collaboration entered into by OnCore, which is now a wholly owned subsidiary on Tekmira, with Blumberg, one of the leading non-profit research institutes in the world focused on HBV.  We believe that this collaboration will provide us with access to cutting-edge research in new target identification, assay development, mechanism of action studies and lead-finding efforts focused on hepatitis B virus. This relationship also provides us with access to research that we believe is equal to, or surpasses that of other biotechnology or pharmaceutical companies, and can add value to our current and future R&D efforts in HBV.

Our RNAi product pipeline is focused on anti-virals, oncology and metabolic product platforms, where there is a significant medical need and commercial opportunity. Our intention is to advance our RNAi product pipeline either ourselves or with partners, with a focus on maximizing the value of these assets.

TKM-HBV

Hepatitis B virus (HBV) causes the most common serious liver infection in the world. The World Health Organization (WHO) estimates that 350 million people worldwide are chronically infected, and other estimates suggest this could include up to 1.4 million people in the United States. Individuals chronically infected with HBV are at an increased risk of developing significant liver disease, including cirrhosis, or permanent scarring of the liver, as well as liver failure and hepatocellular carcinoma (HCC) or liver cancer. According to the Hepatitis B Foundation, HBV is the cause of up to 80% of liver cancers. Individuals with liver cancer typically have a five-year survival rate of only 15%. The WHO estimates that more than 780,000 people die every year due to the consequences of hepatitis B.

Our extensive experience in antiviral drug development has been applied to our TKM-HBV program to develop an RNAi therapeutic for chronic hepatitis B infection. Small molecule nucleotide therapy has been the standard of care for chronic HBV infected patients. However, many of these patients continue to express a viral protein called HBV surface antigen (HBsAg). This protein causes inflammation in the liver leading to cirrhosis and, in some cases, HCC and death.

TKM-HBV is designed to address an unmet medical need and eliminate HBsAg expression in patients chronically infected with HBV. Reducing HBsAg is thought to be a key prerequisite to enable a patient’s immune system to raise an adequate antibody response against the virus. The ability of TKM-HBV to inhibit numerous viral elements in addition to HBsAg increases the likelihood of successfully controlling the viral infection.

TKM-HBV is being developed as a multi-component RNAi therapeutic that simultaneously targets three sites on the HBV genome. Targeting three distinct and highly conserved sites on the HBV genome is intended to facilitate potent knockdown of all viral mRNA transcripts and viral antigens across a broad range of HBV genotypes and reduce the risk of developing antiviral resistance. The goal is for TKM-HBV to be administered without prophylactic steroid treatment.

We presented results from our preclinical studies at the 10th Annual Meeting of the Oligonucleotide Therapeutics Society Meeting held in San Diego, California, on October 15, 2014. Among the results reported is the potent and rapid reduction in HBsAg demonstrated by TKM-HBV in several well-validated models. In these models, TKM-HBV treatment resulted in reductions in both intrahepatic and serum HBsAg, as well as reductions in HBV DNA, covalently closed circular DNA (cccDNA), HBeAg and HBcAg. A rapid 1 log reduction in serum HBsAg was achieved with a single 1 mg/kg dose of TKM-HBV in the humanized mouse model, which closely mimics chronic human hepatitis B infection. 1-2 log viral reductions from similar single-dose LNP treatments in two other true-infection animal models were also demonstrated.

Preclinical studies conducted on infected primary human hepatocytes showed that TKM-HBV had robust and consistent activity against different viral strains representing the major clinical genotypes A, B, C and D. Our data shows that inclusion of three RNAi triggers results in a more broadly effective knockdown of hepatitis B viral elements than a single trigger alone. The mode of action of TKM-HBV complements standard of care nucleoside/nucleotide (NUC) therapy, and lack of drug antagonism has been demonstrated with entecavir, lamivudine and tenofovir on infected primary human hepatocytes, making combination therapy a viable option.

Our data supports the utility of TKM-HBV as a potential new therapeutic option for treating patients with chronic HBV infection. In early 2015, we advanced two TKM-HBV product candidates into a Phase I trial. Both product candidates employ the same unique combination of three RNAi trigger molecules. However, they differ in their LNP composition. One formulation employs a third generation LNP, and the other employs a new, fourth generation LNP, which incorporates novel lipid chemistry and demonstrates improved potency. The multi-component RNAi therapeutic is expected to result in broad and effective inhibition of HBV.

The TKM-HBV Phase I clinical trial is a randomized, single-blind, placebo-controlled study, involving single ascending doses of TKM-HBV. The study will assess the safety, tolerability and pharmacokinetics of intravenous administration of two formulations of TKM-HBV in healthy adult subjects. For each formulation, there are five planned cohorts for a total of 20 subjects (40 in total for both formulations). Four subjects will be enrolled per cohort with three subjects receiving TKM-HBV, and one receiving placebo. We expect the results from the Phase I clinical trial in healthy human volunteers to determine which product formulation will advance into chronically infected patients in a multi-dosing trial in the second half of 2015.

Newly Acquired HBV Candidates as a result of our merger with OnCore

Following Tekmira’s recent merger with OnCore our product development pipeline will now focus on discovery, acquisition or in-licensing and developing drug candidates that attack multiple targets of the HBV lifecycle, including the aggressive suppression of HBV replication and the formation inhibition and elimination of cccDNA. Although the ultimate curative regimens for HBV are currently unknown, we have assembled a robust portfolio of drug development programs targeting hepatitis B, which we plan to evaluate to determine the best potential combination approaches for patients.  These assets include the following:

Cyclophilin Inhibitor — OCB-030

Cyclophilins are proteins that have been shown to play a role in several biological processes, including viral infection. By inhibiting cyclophilin, we believe the ability of HBV to replicate can be impaired and the host immune response toward HBV may be enhanced. We have licensed from NeuroVive Pharmaceutical AB, or NeuroVive, the exclusive rights to develop and commercialize cyclophilin inhibitor drug candidates, including OCB-030, for the treatment of hepatitis B. We are engaged in studies which we expect to be completed in order to file an IND, or equivalent, by year end 2015.

TLR9 Agonist (CYT-003)

Pharmaceutical activation of TLRs is a novel and attractive approach for the treatment of chronic HBV because agonism of these receptors triggers innate immune responses and also stimulates adaptive immunity.  It is hoped that immune stimulation by TLR agonists can overcome the multiple immunologic blocks that allows chronic HBV infection, including direct activation of the host’s innate antiviral response, hence overcoming the functional weakness in HBV-specific immune cell responses.

Licensed from Cytos, CYT003 is a biological carrier which is filled G10 a toll-like receptor-9 (TLR-9) agonist. CYT-003 has been shown to directly activate B cells and stimulates human pDC to secrete Interferon alpha. CYT-003 also activates other antigen presenting cells indirectly and promotes the development of TH1 type cytokine response. This is thought to be potentially beneficial in promoting anti-HBV T cell immunity. CYT003 has previously been utilised in human trials in other indications and therefore could move quickly into the clinic in HBV infected patients. We anticipate initiating preclinical studies to demonstrate proof of concept 1H 2015. If the preclinical studies show utility in HBV, we could likely progress straight into patients given the existing safety database and the open INDs.

Capsid Assembly Inhibitors

We are developing two capsid assembly inhibitors as oral therapeutics for the treatment of chronic HBV infection. By inhibiting assembly of the viral capsid, the ability of hepatitis B virus to replicate is impaired, which subsequently reduces the amount of new virus produced, and may have an effect on cccDNA. We acquired exclusive, worldwide rights to these drug candidates through an in-license from Blumberg and Drexel University, or Drexel, and through OnCore’s recent acquisition of Enantigen Therapeutics, Inc., or Enantigen. We expect to file an IND with the FDA, or an equivalent filing with foreign regulatory authorities, and initiate Phase 1 studies with one of these compounds in 2016.

Surface Antigen Secretion Inhibitors

We are developing multiple small molecule orally bioavailable HBV surface antigen secretion inhibitors. By inhibiting the secretion of HBV surface antigen from infected cells, we expect that the immune response of patients treated with this therapy can reengage and thereby mount a more credible response to a hepatitis B virus infection. We acquired these drug candidates through OnCore’s recent acquisition of Enantigen. We expect to file an IND, or its equivalent in another territory, for a lead compound in 2016.

STING Agonists

We are developing STING (stimulator of interferon genes) agonists. By activating interferon genes, we anticipate that the body can produce additional interferon alpha and beta, which have antiviral properties. Our development program, which is currently in the discovery research stage, is based on proof of concept data in mice generated by Blumberg which showed that STING agonists can elicit an antiviral response and inhibit HBV replication in mouse liver cells. In collaboration with Blumberg, our plan is to identify potent, orally active small molecule human STING agonists that possess the desired characteristics to progress into human clinical studies.

 
41

 
cccDNA Formation Inhibitors

We are developing multiple series of cccDNA formation inhibitors. The inhibition of cccDNA formation would reduce the amount of cccDNA in the infected liver cell and could ultimately eliminate the reservoir of HBV genomic material required for continued viral replication. We acquired the exclusive, worldwide rights to this program through an in-license from Blumberg. This program is currently in early optimization and we anticipate filing an IND with the FDA or its equivalent in another territory in 2017.

cccDNA Epigenetic Modifiers

In addition to cccDNA formation inhibitors, we are developing cccDNA epigenetic modifiers. By controlling cccDNA transcription, we anticipate that we may be able to inhibit the formation of new virus and subviral particles from cccDNA. This development program, which is currently in the discovery research stage, is based on proof of concept data generated by Blumberg using known inhibitors of enzymes involved in DNA information processing.

Non-HBV Assets Clinical Programs TKM-PLK1, TKM-Ebola, TKM-Ebola-Guinea (LNP Enabled)

We believe there is significant value in our non-HBV assets and remain committed to maximizing this value. We intend to continue our clinical programs to the appropriate point in support of this objective. We also remain interested in advancing our ongoing metabolic and rare disease preclinical programs in an appropriate way toward this value maximization objective and in continuing to leverage our knowledge and expertise in LNP technology.
 
TKM-PLK1
 
Our oncology product platform, TKM-PLK1, targets polo-like kinase 1 (PLK1), a protein involved in tumor cell proliferation and a validated oncology target. Inhibition of PLK1 expression prevents the tumor cell from completing cell division, resulting in cell cycle arrest and death of the cancer cell. Evidence that patients with elevated levels of PLK1 in their tumors exhibit poorer prognosis and survival rates has been documented in the medical literature. TKM-PLK1 is being evaluated in oncology indications in which there are limited or ineffective therapies available: Gastrointestinal Neuroendocrine Tumors (GI-NET), Adrenocortical Carcinoma (ACC) and Hepatocellular Carcinoma (HCC).

GI-NET and ACC

GI-NET is the gastrointestinal subset of neuroendocrine tumors. According to a paper by Yao et al. (2008), a historical analysis of the US SEER database reveals the incidence of neuroendocrine tumors has increased faster in the last few decades than any other neoplasm, with a growth rate of greater than 3% expected to continue in the near term. The prevalence of GI-NET in the US is estimated to be approximately 55,000 individuals. Prognosis for advanced or metastatic GI-NET, the target population for TKM-PLK1, is poor with 25-54% of patients surviving less than one year.

ACC is an ultra-rare form of cancer that develops in the adrenal gland, with data from the US National Cancer Institute estimating 500 patients in the US. Survival prognosis for these patients is poor. A large percentage of patients are not good surgical candidates and there is a lack of effective systemic therapies.

We presented updated Phase I TKM-PLK1 data at the 6th Annual NET Conference hosted by the North American Neuroendocrine Tumor Society (NA-NETS) in Charleston, South Carolina on October 4, 2013. This data set included a total of 36 patients in a population of advanced cancer patients with solid tumors. Doses ranged from 0.15 mg/kg to 0.90 mg/kg during the dose escalation portion of the trial, with the maximum tolerated dose (MTD) of 0.75 mg/kg. Serious adverse events (SAEs) were experienced by four subjects in this heavily pre-treated, advanced cancer patient population, with three of four subjects continuing on study. Forty percent (6 out of 15) of patients evaluable for response, treated at a dose equal to or greater than 0.6 mg/kg, showed clinical benefit. Three out of the four ACC patients (75%) treated with TKM-PLK1 achieved stable disease, including one patient who saw a 19.3% reduction in target tumor size after two cycles of treatment and is still on study receiving TKM-PLK1. Of the two GI-NET patients enrolled, both experienced clinical benefit: one patient had a partial response based on Response Evaluation Criteria in Solid Tumors (RECIST) criteria, and the other GI-NET patient achieved stable disease and showed a greater than 50% reduction in Chromogranin-A (CgA) levels, a key biomarker used to predict clinical outcome and tumor response.

Based on encouraging results from the dose escalation portion and expansion cohort from our Phase I TKM-PLK1 clinical trial, we expanded into a Phase I/II clinical trial with TKM-PLK1, which is specifically enrolling patients within two therapeutic indications: advanced GI-NET or ACC. This multi-center, single arm, open label study is designed to measure efficacy using RECIST criteria for GI-NET patients and ACC patients as well as evaluate the safety, tolerability and pharmacokinetics of TKM-PLK1. TKM-PLK1 is administered weekly with each four-week cycle consisting of three once-weekly doses followed by a rest week. In the fall of 2014, we achieved our enrolment target of patients with advanced GI-NET or ACC tumors. These patients will continue treatment and be followed to determine if TKM-PLK1 produces a meaningful clinical benefit.

We provided an update on this Phase I/II clinical study in December 2014. To date, 55 patients, in both the Phase I and Phase I/II studies have been treated at doses of ≥ 0.6 mg/kg, which is considered to be in the efficacious dose range based on preclinical studies. Of these, 31 patients comprise the target population of GI-NET or ACC patients. Currently, nine patients (GI-NET and ACC) remain actively on treatment and data collection is ongoing.

 
42

 
While we are still awaiting maturation of data, we continue to see evidence of anti-tumor activity in some treated subjects, including one ACC patient with an almost complete resolution of their disease. We expect to report final data from these studies in the second half of 2015.

HCC

HCC is one of the most common cancers and one of the most deadly, with over 650,000 deaths each year worldwide according to the Globocan 2012 database.  US incidence is estimated at 27,000 individuals with annual growth rates greater than 2%. HCC is an aggressive, hard-to-treat disease with one-year survival rates of less than 50% and five-year rates as low as 4% (National Cancer Institute). To date, Nexavar (sorafenib) is the only agent approved to treat HCC with an improvement in overall survival of just two to three months.

In May 2014, we initiated another Phase I/II clinical trial with TKM-PLK1, enrolling patients with advanced HCC. Patient dosing has commenced and we have completed the first treatment in all of our subjects for the first HCC cohort. This Phase I/II clinical trial is a multi-center, single arm, open label dose escalation study designed to evaluate the safety, tolerability and pharmacokinetics of TKM-PLK1 as well as determine the maximum tolerated dose in patients with advanced HCC. It will also include a preliminary assessment of the anti-tumor activity of TKM-PLK1 in this patient population. It is expected that approximately 38 patients with advanced HCC tumors will be enrolled in this Phase I/II clinical trial.

TKM-Ebola

TKM-Ebola, an anti-Ebola RNAi therapeutic, is being developed under a $140 million contract, signed in July 2010, with the U.S. Department of Defense (DoD) Joint Project Manager Medical Countermeasure Systems BioDefense Therapeutics (JPM-MCS-BDTX). Preclinical studies published in the medical journal The Lancet in 2010 demonstrated that when RNAi triggers targeting the Ebola virus and delivered by our LNP technology were used to treat previously infected non-human primates, the result was 100 percent protection from an otherwise lethal dose of Zaire Ebola virus (Geisbert et al., The Lancet, Vol. 375, May 29, 2010).

In May 2013, our collaboration with the JPM-MCS-BDTX was modified and expanded to include advances in LNP formulation technology. The contract modification increased the first stage of funding from $34.7 million to $41.7 million. In April 2014, we signed a second contract modification to increase this funding by $2.1 million to a total of $43.8 million to compensate Tekmira for unrecovered costs that occurred in 2012 and to provide additional funding should it be required.

TKM-Ebola is being developed under specific U.S. Food and Drug Administration (FDA) regulatory guidelines called the “Animal Rule.” This allows, in circumstances where it is unethical or not feasible to conduct human efficacy studies, marketing approval to be granted based on adequate and well-controlled animal studies when the results of those studies establish that the drug is reasonably likely to produce clinical benefit in humans.  Demonstration of the product’s safety in humans is still required.

We were granted Fast Track designation from the FDA for the development of TKM-Ebola in March 2014. The FDA’s Fast Track is a process designed to facilitate the development and expedite the review of drugs in order to get important new therapies to the patient earlier.

In May 2014, we successfully completed the single ascending dose portion of the TKM-Ebola Phase I clinical trial in healthy human volunteers. Results demonstrated that administration of the TKM-Ebola therapeutic, in the absence of any steroid containing pre-medication, was well-tolerated at a dose level of 0.3 mg/kg, determined to be the maximum tolerated dose.

In July 2014, we received notice from the FDA placing the TKM-Ebola Investigational New Drug application (IND) on clinical hold until additional information is supplied, and the multiple ascending dose portion of the trial protocol is modified to ensure the safety of healthy volunteers. The clinical hold was subsequently modified to a partial clinical hold to permit the administration of TKM-Ebola to patients with a suspected or confirmed Ebola virus infection. Under the FDA’s expanded access program, several patients with a confirmed or suspected Ebola virus infection were treated with TKM-Ebola. Data is being collected and will be provided to the FDA under our IND. Health Canada also established a similar framework for the potential use of TKM-Ebola in the same group of patients.

With the emergency use of our TKM-Ebola product under expanded access protocols and recent developments, such as the production of a new product candidate for clinical trials in West Africa, the clinical development pathways for our Ebola products are evolving. We may not be able to resolve the partial clinical hold of the healthy volunteer, multiple ascending dose portion of our Phase 1 trial of TKM-Ebola.

In December 2014, the US Congress amended the Rare and Tropical Disease list to include Ebola as a candidate for a potential Accelerated Review Voucher.
 
TKM-Ebola-Guinea, an Anti-Ebola RNAi Therapeutic Targeting Ebola-Guinea Strain of Ebola Virus

In September 2014, we joined an international consortium led by the International Severe Acute Respiratory and Emerging Infection Consortium (ISARIC) at the University of Oxford, UK, to potentially provide an RNAi based investigational therapeutic for expedited clinical studies in West Africa.

 
43

 
In October 2014, the genomic sequence of the Ebola-Guinea strain, which is the virus responsible for the recent outbreak in West Africa, was determined from several viral isolates and published in the New England Journal of Medicine (Baize S., et al. Emergence of Zaire Ebola Virus Disease in Guinea; New England Journal of Medicine, October 9, 2014 Vol. 371 No. 15). We rapidly developed a modified RNAi therapeutic to specifically target Ebola-Guinea. The new product, TKM-Ebola-Guinea, is designed to match the genomic sequence exactly, with two RNAi molecule triggers. Results of preclinical studies with TKM-Ebola-Guinea demonstrated efficacy comparable to those obtained with TKM-Ebola, which demonstrated up to 100% protection from an otherwise lethal dose of the virus.
 
In December 2014, we entered into a Manufacturing and Clinical Trial Agreement with the University of Oxford to provide the new TKM-Ebola-Guinea therapeutic product for clinical studies in West Africa. ISARIC can conduct clinical studies of TKM-Ebola-Guinea in Ebola virus infected patients, with funding provided by the Wellcome Trust. GMP manufacture of TKM-Ebola-Guinea is now complete and 100 treatment courses are available for the study. A Phase II single arm trial called RAPIDE (Rapid Assessment of Potential Interventions & Drugs for Ebola), was initiated in March 2015 in Sierra Leone. The study is open-label with a concurrent observational study in Ebola, and results are expected in the second half of 2015.

The U.S. Department of Defense JPM-MCS-BDTX has also exercised an option, valued at $7.0 million, in our current contract to manufacture TKM-Ebola-Guinea. We have been awarded the option for scale-up and GMP manufacture of the product for approximately 500 treatment courses.

Non-HBV Preclinical Candidates (LNP enabled)

We are currently evaluating several additional preclinical candidates with potential in diverse therapeutic areas. Given the extremely high efficiency of delivery for third and fourth generation liver-centric LNP formulations, we are focused on rare diseases where the molecular target is found in the liver, early clinical proof-of-concept can be achieved and development opportunities may be accelerated. Our research team intends to continue to generate preclinical data to support the advancement of the most promising of these targets.
 
TKM-Marburg

Like Ebola, Marburg is a member of the filovirus family of hemorrhagic fever viruses. Natural outbreaks with the Marburg-Angola strain have resulted in mortality in approximately 90% of infected individuals. There are currently no approved therapeutics available for the treatment of Marburg infection.

In 2010, along with the University of Texas Medical Branch (UTMB), we were awarded a National Institutes of Health (NIH) grant to support research to develop RNAi therapeutics to treat Ebola and Marburg hemorrhagic fever viral infections. In November 2013, we announced data showing 100% survival in non-human primates infected with the Angola strain of the Marburg virus in two separate studies. These results build upon a study published earlier in the Journal of Infectious Disease showing 100% protection in guinea pig models of infection with Angola, Ci67 and Ravn strains of the Marburg virus using a broad spectrum RNAi therapeutic enabled by Tekmira’s LNP.

In February 2014, along with UTMB, and other collaborators, we were awarded additional funding from the NIH in support of this research. Data was published demonstrating complete protection of non-human primates against lethal Marburg-Angola strain, (Science Translational Medicine. Thi EP., et al. Marburg virus infection in nonhuman primates: Therapeutic treatment by lipid-encapsulated siRNA. 2014 Aug 20;6 (250))
 
TKM-HTG

Our metabolic product platform, TKM-HTG, aims to achieve rapid and sustained reductions of triglycerides to address the limitations of existing Hypertriglyceridemia (HTG) treatments. Hypertriglyceridemia is a type of dyslipidemia where there are high blood levels of triglycerides. Patients with severe HTG, (classified as triglyceride levels greater than 1000 mg/dL) are at risk of acute pancreatitis as well as the risk of cardiovascular disease. Approximately one million adults in the US and 18 million worldwide suffer from severe HTG. (NHANES 2003-2004 data).

Another patient group affected by HTG are those with Familial Chylomicronemia Syndrome (FCS), which is a very rare hereditary condition affecting an estimated 1:1,000,000 people (www.fcs.raredr.com). Additionally, 35% of patients with Type 2 Diabetes (T2D) suffer from mixed hyperlipidemia which is a combination of elevated cholesterol and high triglycerides. With underlying T2D, these patients are at considerable risk from cardiovascular disease.

TKM-HTG is being developed as a multi-component RNAi therapeutic that simultaneously targets a combination of genes expressed in the liver, which are known to play a significant role in triglyceride metabolism. High triglyceride levels are medically linked to increased risk of cardiovascular disease, fatty liver disease, insulin resistance and pancreatitis.

We anticipate filing an investigational new drug application, or equivalent document, in the second half of 2015.

TKM-ALDH
 
TKM-ALDH is designed to knockdown or silence aldehyde dehydrogenase (ALDH) to induce long term acute sensitivity to ethanol, for use in severe alcohol use disorder. Aldehyde dehydrogenase is a key enzyme in ethanol metabolism. Inhibition of ALDH activity, through the silencing of ALDH results in the build-up of acetaldehyde leading to adverse physiological effects. Human proof of concept for ALDH inhibition already exists in the form of the approved drug disulfiram. However, disulfiram’s efficacy is compromised by poor compliance because it has to be taken daily. We believe TKM-ALDH will induce prolonged ethanol sensitivity that will enable it to overcome the compliance limitations associated with daily dosing. We are exploring partnering or external funding opportunities to maximize the value of this asset.
 
Ongoing Advancements in LNP Technology
 
We plan to continue to develop our proprietary LNP delivery technology and receive clinical validation from LNP-based products currently in clinical trials. The most advanced LNP-enabled therapeutic, which is being developed by Alnylam Pharmaceuticals, Inc., has entered a Phase III clinical trial. We believe our LNP technology can remain an important cornerstone of our business development activities moving forward. We recently announced the latest (fourth) generation of the platform which comprises a rational re-design of the lipid architecture, as well as formulation and process advances. These attributes can be utilized in programs entering the clinic in 2015 and are expected to yield significant increases in potency and therapeutic index.

Because LNP can enable a wide variety of nucleic acid triggers, including messenger RNA (mRNA), we continue to see new product development and partnering opportunities based on what we believe is our industry-leading delivery expertise. In February 2014, we presented new preclinical data at the AsiaTIDES scientific symposium in Tokyo, Japan demonstrating that mRNA can be effectively delivered to target proteins expressed.
 
Technology, Product Development and Licensing Agreements
 
In the field of RNAi therapeutics, we have licensed our LNP delivery technology to Alnylam and Merck & Co., Inc. Alnylam has provided royalty bearing access of our LNP delivery technology to some of its partners. We also have a licensing and collaboration agreement with Dicerna Pharmaceuticals, Inc.  In addition, we have ongoing research relationships with Monsanto, the United States National Cancer Institute, the US Department of Defense's BioDefense Therapeutics program and other undisclosed pharmaceutical and biotechnology companies. Outside the field of RNAi, we have a legacy licensing agreement with Spectrum Pharmaceuticals, Inc.

We have rights under the RNAi intellectual property of Alnylam to develop 13 RNAi therapeutic products. In addition, we have a broad non-exclusive license to use Unlocked Nucleobase Analogs (UNAs) from Arcturus Therapeutics, Inc. for the development of RNAi therapeutic products directed to any target in any therapeutic indication.
 
Strategic Alliances
 
Alnylam Pharmaceuticals, Inc. (“Alnylam”)
 
Alnylam has a license to use our Intellectual Property (IP) to develop and commercialize products and may only grant access to our LNP technology to its partners if it is part of a product sublicense. Alnylam’s license rights are limited to patents that we filed, or that claim priority to a patent that was filed, before April 15, 2010. Alnylam does not have rights to our patents filed after April 15, 2010 unless they claim priority to a patent filed before that date. Alnylam will pay us low single digit royalties as Alnylam’s LNP-enabled products are commercialized. Alnylam currently has three LNP-based products in clinical development: ALN-TTR02 (patisiran), ALN-VSP, and ALN-PCS02.
 
In November 2013, Alnylam presented positive results from its Phase II clinical trial with patisiran (ALN-TTR02), an RNAi therapeutic targeting transthyretin (TTR) for the treatment of TTR-mediated amyloidosis (ATTR), which is enabled by our LNP technology. Alnylam also announced the initiation of the APOLLO Phase III trial of patisiran, with the study now open for enrolment to evaluate efficacy and safety of patisiran in ATTR patients with Familial Amyloidotic Polyneuropathy (FAP).
 
In December 2013, we received a $5 million milestone from Alnylam, triggered by the initiation of the APOLLO Phase III trial of patisiran. We have entered an arbitration proceeding with Alnylam, as provided for under our licensing agreement, to resolve a matter related to a disputed $5 million milestone payment to Tekmira by Alnylam for its ALN-VSP product. We have not recorded any revenue in respect of this milestone.
 
In April 2014, Alnylam presented positive new data from its Phase II clinical trial with patisiran. These results provide support for Alnylam's Phase III APOLLO trial in which patisiran is being evaluated for its potential efficacy and safety in ATTR patients with FAP. Alnylam has disclosed that it continues to enrol patients in its APOLLO Phase III trial, with over 20 sites in nine countries, which are now open and active. The Phase III trial is intended to demonstrate the efficacy and safety of patisiran in support of marketing authorization in countries around the world.

 
45

 
In October 2014, Alnylam reported positive clinical data for the ongoing patisiran Phase II Open Label Extension (OLE) study in patients with FAP, which is also enabled by Tekmira’s LNP technology. The results demonstrated sustained knockdown of serum TTR of up to 90% and a favorable tolerability profile out to one year of treatment.

The patisiran program represents the most clinically advanced application of Tekmira’s proprietary LNP delivery technology. Furthermore, Alnylam’s results demonstrate that multi-dosing with Tekmira’s LNP has been well-tolerated with treatments out to one year.

Our licensing agreement with Alnylam grants us IP rights for the development and commercialization of RNAi therapeutics for specified targets. In consideration for these three exclusive and 10 non-exclusive licenses, we have agreed to pay single-digit royalties to Alnylam on product sales, with milestone obligations of up to $8.5 million on the non-exclusive licenses and no milestone obligations on the three exclusive licenses.

Acuitas Therapeutics Inc. (“Acuitas”)

Consistent with the terms of the settlement agreement signed in November 2012, we finalized and entered a cross-license agreement with Acuitas (formerly AlCana Technologies, Inc.) in December 2013. The terms of the cross-license agreement provide Acuitas with access to certain of Tekmira’s earlier IP generated prior to April 2010 and provide us with certain access to Acuitas’ technology and licenses in the RNAi field, along with a percentage of each milestone and royalty payment with respect to certain products. Acuitas has agreed that it will not compete in the RNAi field for a period of five years.
 
Spectrum Pharmaceuticals, Inc. (“Spectrum”)
 
In September 2013, we announced that our licensee, Spectrum, had launched Marqibo® through its existing hematology sales force in the United States. Since then commercial sales have occurred. We are entitled to mid-single digit royalty payments based on Marqibo®’s commercial sales. Marqibo, which is a novel sphingomyelin/cholesterol liposome-encapsulated formulation of the FDA-approved anticancer drug vincristine, was originally developed by Tekmira. We out-licensed the product to Talon Therapeutics in 2006 and in July 2013, Talon was acquired by Spectrum. Marqibo’s approved indication is for the treatment of adult patients with Philadelphia chromosome-negative acute lymphoblastic leukemia (Ph-ALL) in second or greater relapse or whose disease has progressed following two or more lines of anti-leukemia therapy. Spectrum has ongoing trials evaluating Marqibo in three additional indications, which are: first line use in patients with Ph-ALL, Pediatric ALL and Non-Hodgkin’s lymphoma.
 
Monsanto Company (“Monsanto”)
 
In January 2014, we signed an Option Agreement and a Service Agreement with Monsanto, pursuant to which Monsanto may obtain a license to use our proprietary delivery technology. The transaction supports the application of our proprietary delivery technology and related IP for use in agriculture. The potential value of the transaction could reach $86.2 million following the successful completion of milestones. In January 2014, we received $14.5 million of the $17.5 million in near term payments. We received additional payments of $1.5 M each in June 2014 and October 2014 following achievement of specific program objectives.
 
Marina Biotech, Inc.  (“Marina”) / Arcturus Therapeutics, Inc. (“Arcturus”)
 
In November 2012, we disclosed that we had obtained a worldwide, non-exclusive license to a novel RNAi trigger technology called Unlocked Nucleobase Analog (UNA) from Marinaa for the development of RNAi therapeutics. UNAs can be incorporated into RNAi drugs and have the potential to improve them by increasing their stability and reducing off-target effects. In August 2013, Marina assigned its UNA technology to Arcturus and the UNA license agreement between Tekmira and Marina was assigned to Arcturus. The terms of the license are otherwise unchanged.
 
To date, we have paid Marina $0.5 million in license fees and there are milestones of up to $3.2 million plus royalties for each product that we develop using UNA technology licensed from Marina.  We announced on January 21, 2015, that we had initiated a Phase I clinical trial with TKM-HBV. As TKM-HBV utilizes UNA technology in-licensed from Arcturus, the initiation of the trial triggered a single milestone payment of $250,000 payable by us to Arcturus. 
 
Merck & Co., Inc. ("Merck") and Alnylam license agreement

As a result of the business collaboration with Protiva in 2008, we acquired a non-exclusive royalty-bearing world-wide license agreement with Merck. Under the license, Merck will pay up to $17 million in milestones for each product they develop covered by Protiva’s IP, except for the first product for which Merck will pay up to $15 million in milestones, and will pay royalties on product sales. Merck’s license rights are limited to patents that we filed, or that claim priority to a patent that was filed, before October 9, 2008. Merck does not have rights to our patents filed after October 9, 2008 unless they claim priority to a patent filed before that date. Merck has also granted a license to Tekmira to certain of its patents.  On March 6, 2014, Alnylam announced that they acquired all assets and licenses from Merck, which included our license agreement.
 
Bristol-Myers Squibb Company (“BMS”)

In May 2010, we announced a research collaboration with BMS. Under this agreement, BMS conducted preclinical work to validate the function of certain genes and shared the data with us to potentially develop RNAi therapeutic drugs against therapeutic targets of interest. We formulated the required RNAi trigger molecules enabled by our LNP technology to silence target genes of interest.  BMS paid us $3 million concurrent with the signing of the agreement. We provided a predetermined number of LNP batches over the four-year agreement.  In May 2011, we announced a further expansion of the collaboration to include broader applications of our LNP technology and additional target validation work. In May 2014, the collaboration expired and both parties’ obligations ended.

 
46

 
U.S. National Institutes of Health (“NIH”)
 
On October 13, 2010 we announced that together with collaborators at The University of Texas Medical Branch (“UTMB”), we were awarded a new NIH grant, worth $2.4 million, to support research to develop RNAi therapeutics to treat Ebola and Marburg hemorrhagic fever viral infections using our LNP delivery technology. In February 2014, UTMB and Tekmira, along with other collaborators, were awarded additional funding of $3.4 million over five years from the NIH in support of this research.
 
Halo-Bio RNAi Therapeutics, Inc. ("Halo-Bio")
 
In August 2011, we entered into a license and collaboration agreement with Halo-Bio. Under the agreement, Halo-Bio granted to us an exclusive license to its multivalent ribonucleic acid MV-RNA technology. The agreement was amended on August 8, 2012 to adjust future license fees and other contingent payments. To date, we have recorded $0.5 million in fees under our license from Halo-Bio. We terminated the agreement with Halo-Bio in July 2013. There are no further payments due or contingently payable to Halo-Bio.
 
Dicerna Pharmaceuticals, Inc. (“Dicerna”)

In November 2014, Tekmira signed a licensing agreement and a development and supply agreement with Dicerna to license Tekmira's LNP delivery technology for exclusive use in Dicerna's primary hyperoxaluria type 1 (PH1) development program. Dicerna will use Tekmira's third generation LNP technology for delivery of DCR-PH1, Dicerna's product incorporating its Dicer substrate RNA (DsiRNA) molecule, for the treatment of PH1, a rare, inherited liver disorder that often results in kidney failure and for which there are no approved therapies. Under the agreements, Dicerna paid Tekmira $2.5 million upfront and will potentially make payments of $22 million in aggregate development milestones, plus a mid-single-digit royalty on future PH1 sales. This partnership also includes a supply agreement under which we will provide clinical drug supply and regulatory support for the rapid advancement of this product candidate.
 
Newly acquired assets as a result of our merger with OnCore
 
In addition to the newly acquired product candidates discussed above, our merger with OnCore resulted in the acquisition of the following:
 
Cytos Biotechnology Ltd (“Cytos”)
 
On December 30, 2014, OnCore entered into an exclusive, worldwide, sub-licensable (subject to certain restrictions with respect to licensed viral infections other than hepatitis) license to six different series of compounds. The licensed compounds are Qbeta-derived virus-like particles that encapsulate TLR9, TLR7 or RIG-I agonists and may or may not be conjugated with antigens from hepatitis virus or other licensed viruses.  We have an option to expand this license to include additional viral infections other than influenza and Cytos will retain all rights for influenza, all non-viral infections, and all viral infections (other than hepatitis) for which we have not exercised an option. 
 
In partial consideration for this license, upon closing of the Cytos Agreement we will be obligated to pay Cytos up to a total of $67 million for each of the six licensed compound series upon the achievement of specified development and regulatory milestones; for hepatitis and each additional licensed viral infection, up to a total of $110 million upon the achievement of specified sales performance milestones; and tiered royalty payments in the high-single to low-double digits, based upon the proportionate net sales of licensed products in any commercialized combination.
 
The Baruch S. Blumberg Institute (“Blumberg”) and Drexel University (“Drexel”)

In February 2014, OnCore entered into a license agreement with Blumberg and Drexel that granted us an exclusive (except as to certain know-how and subject to retained non-commercial research rights), worldwide, sub-licensable license to three different compound series: cccDNA inhibitors, capsid assembly inhibitors and HCC inhibitors.
 
In partial consideration for this license, OnCore paid a license initiation fee of $150,000 and issued warrants to Blumberg and Drexel. Under this license agreement, OnCore also agreed to pay up to $3.5 million in development and regulatory milestones per licensed compound series, up to $92.5 million in sales performance milestones per licensed product, and royalties in the mid-single digits based upon the proportionate net sales of licensed products in any commercialized combination. We are obligated to pay Blumberg and Drexel a double digit percentage of all amounts received from the sub-licensees, subject to customary exclusions.
 
In November 2014, OnCore entered into an additional license agreement with Blumberg and Drexel pursuant to which OnCore received an exclusive (subject to retained non-commercial research rights), worldwide, sub-licensable license under specified patents and know-how controlled by Blumberg and Drexel covering epigenetic modifiers of cccDNA and STING agonists. In consideration for these exclusive licenses, OnCore made an upfront payment of $50,000. Under this agreement, we will be required to pay up to $1.0 million for each licensed product upon the achievement of a specified regulatory milestone and a low single digit royalty, based upon the proportionate net sales of compounds covered by this intellectual property in any commercialized combination. We are also obligated to pay Blumberg and Drexel a double digit percentage of all amounts received from its sub-licensees, subject to exclusions. 
 
License Agreements between Enantigen (“Enantigen”) and Blumberg and Drexel
 
In October 2014, OnCore acquired all of the outstanding shares of Enantigen pursuant to a stock purchase agreement. Through this transaction, OnCore acquired a HBV surface antigen secretion inhibitor program and a capsid assembly inhibitor program, each of which are now assets of Tekmira, following the merger with OnCore.
 
Under the stock purchase agreement, we agreed to pay up to a total of $21.0 million to Enantigen’s selling stockholders upon the achievement of specified development and regulatory milestones, for the first two products that contain either a capsid compound, or a HBV surface antigen compound that is covered by a patent that acquired under this agreement, or a capsid compound from an agreed upon list of compounds, up to a total of $101.5 million in sales performance milestones in connection with the sale of the first commercialized product of Tekmira for the treatment of HBV, regardless of whether such product is based upon assets acquired under this agreement, and low single digit royalty on net sales of such first commercialized HBV product, up to a maximum royalty payment of $1.0 million that, if paid, would be offset against our milestone payment obligations.
 
 
47

 
Under the stock purchase agreement, we also agreed that Enantigen would cause Enantigen to fulfill its obligations under Enantigen’s three patent license agreements with Blumberg and Drexel. Pursuant to each patent license agreement, Enantigen is obligated to pay Blumberg and Drexel up to approximately $500,000 in development and regulatory milestones per licensed product, royalties in the low single digits, and a percentage of revenue it receives from its sub-licensees.
 
Research Collaboration and Funding Agreement with Blumberg

In October 2014, OnCore entered into a research collaboration and funding agreement with Blumberg under which we will provide $1.0 million per year of research funding for three years, renewable at our option for an additional three years, for Blumberg to conduct research projects in HBV and liver cancer pursuant to a research plan to be agreed upon by the parties. Blumberg has exclusivity obligations to Tekmira with respect to HBV research funded under the agreement. In addition, we have the right to match any third party offer to fund HBV research that falls outside the scope of the research being funded under the agreement. Blumberg has granted us the right to obtain an exclusive, royalty bearing, worldwide license to any intellectual property generated by any funded research project. If we elect to exercise our right to obtain such a license, we will have a specified period of time to negotiate and enter into a mutually agreeable license agreement with Blumberg. This license agreement will include the following pre negotiated upfront, milestone and royalty payments: an upfront payment in the amount of $100,000; up to $8.1 million upon the achievement of specified development and regulatory milestones; up to $92.5 million upon the achievement of specified commercialization milestones; and royalties at a low single to mid-single digit rates based upon the proportionate net sales of licensed products from any commercialized combination.
 
NeuroVive Pharmaceutical AB (“NeuroVive”)
 
In September 2014, OnCore entered into a license agreement with NeuroVive that granted us an exclusive, worldwide, sub-licensable license to develop, manufacture and commercialize, for the treatment of HBV, oral dosage form sanglifehrin based cyclophilin inhibitors (including OCB-030). Under this license agreement we have been granted a non-exclusive, royalty free right and license and right of reference to NeuroVive’s relevant regulatory approvals and filings for the sole purpose of developing, manufacturing and commercializing licensed products for the treatment of HBV. Under this license agreement, we have (1) an option to expand our exclusive license to include treatment of viral diseases other than HBV and (2) an option, exercisable upon specified conditions, to expand our exclusive license to include development, manufacture and commercialization of non-oral variations of licensed products for treatment of viral diseases other than HBV. NeuroVive retains all rights with respect to development, manufacture and commercialization of licensed products and non-oral variations of licensed products for all indications (other than HBV) for which we have not exercised our option.
 
In partial consideration for this license, OnCore paid NeuroVive a license fee of $1 million. We are also obligated to pay up to $47.0 million in clinical development and regulatory milestones per indication and up to $102.5 million in sales performance milestones per licensed product and indication. If we are acquired by a third party in a transaction that meets certain criteria, then we or our acquiror will be obligated to pay all remaining development, regulatory and sales milestone payments, regardless of whether the applicable milestone events have been achieved, for each licensed product that entered clinical development before such acquisition. We agreed to pay NeuroVive tiered royalties in the mid-single to low-double digit range based upon the proportionate gross sales of patented licensed products from any commercialized combination. If we terminate this license agreement in its entirety for convenience prior to the first commercial sale of any licensed product, we will be obligated to pay NeuroVive $2 million.
 
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
 
The significant accounting policies that we believe to be most critical in fully understanding and evaluating our financial results are revenue recognition, stock-based compensation, share purchase warrant valuation and financial instrument valuation.  These accounting policies require us to make certain estimates and assumptions.  We believe that the estimates and assumptions upon which we rely are reasonable, based upon information available to us at the time that these estimates and assumptions are made.  Actual results may differ from our estimates. Our critical accounting estimates affect our net income or loss calculation.
 
Revenue Recognition / Our primary sources of revenue have been derived from research and development collaborations and contracts, and licensing fees comprised of initial fees and milestone payments.  Payments received under research and development agreements and contracts, which are non-refundable, are recorded as revenue as services are performed and as the related expenditures are incurred pursuant to the agreement, provided collectability is reasonably assured. Revenue earned under research and development manufacturing collaborations where we bear some or all of the risk of a product manufacture failure is recognized when the purchaser accepts the product and there are no remaining rights of return. Revenue earned under research and development collaborations and contracts where we do not bear any risk of product manufacture failure is recognized in the period the work is performed. Revenue earned under contractual arrangements upon the achievement of substantive milestones is recognized in its entirety in the period the payment has been received. We evaluate whether milestones under research and development arrangements are substantive by considering: whether substantive uncertainty exists upon the execution of the arrangement; the event can only be achieved based in whole or in part on our performance or occurrence of a specific outcome resulting from the our performance; any future performance required and payment is reasonable relative to all deliverables; and, payment terms in the arrangement. Initial fees and non-substantive milestone payments are deferred and amortized into income over the estimated period of our involvement as we fulfill our obligations under our agreements.  
 
48

 
The revenue that we recognize is a critical accounting estimate because of the volume and nature of the revenues we receive.  Some of the research, development and licensing agreements that we have entered into contain multiple revenue elements that are to be recognized for accounting in accordance with our revenue recognition policy.  We need to make estimates as to what period the services will be delivered with respect to up-front licensing fees and milestone payments received because these payments are deferred and amortized into income over the estimated period of our ongoing involvement.  The actual period of our ongoing involvement may differ from the estimated period determined at the time the payment is initially received and recorded as deferred revenue.  This may result in a different amount of revenue that should have been recorded in the period and a longer or shorter period of revenue amortization. When an estimated period changes we amortize the remaining deferred revenue over the estimated remaining time to completion.  The rate at which we recognize revenue from payments received for services to be provided under research and development agreements depends on our estimate of work completed to date and total work to be provided. The actual total services provided to earn such payments may differ from our estimates.
 
Our DoD contract for TKM-Ebola is based on cost reimbursement plus an incentive fee. At the beginning of our fiscal year we estimate our labor and overhead rates for the year ahead. During the year, we re-estimate our labor and overhead rates and adjust our revenue accordingly. Our actual labor and overhead rates will differ from our estimate based on actual costs incurred and the proportion of our efforts on contracts and internal products versus indirect activities. Within minimum and maximum collars, the amount of incentive fee we can earn under the DoD contract varies based on our costs incurred versus budgeted costs, with the exception of the Ebola-Guinea Amendment, which has a fixed incentive fee. During the contractual period, incentive fee revenue and total costs are impacted by management’s estimate and judgments which are continuously reviewed and adjusted, as necessary, using the cumulative catch-up method.  At December 31, 2012, we were not able to make a reliable estimate of the final contract costs, and only the minimum incentive fee achievable and earned was recognized. For the years ended December 31, 2013 and 2014, we believe we were able to reliably estimate the final contract costs so have recognized the portion of expected incentive fee which has been earned to date.
 
Our revenue for 2014 was $15.0 million (2013 - $15.5 million, 2012 - $14.1 million) and deferred revenue at December 31, 2014 was $15.7 million (December 31, 2013 - $3.5 million).
 
Stock-based compensation / The stock-based compensation that we record is a critical accounting estimate due to the value of compensation recorded, the volume of our stock option activity, and the many assumptions that are required to be made to calculate the compensation expense.
 
Compensation expense is recorded for stock options issued to employees and directors using the fair value method.  We must calculate the fair value of stock options issued and amortize the fair value to stock compensation expense over the vesting period, and adjust the expense for stock option forfeitures and cancellations.  We use the Black-Scholes model to calculate the fair value of stock options issued which requires that certain assumptions, including the expected life of the option and expected volatility of the stock, be estimated at the time that the options are issued.  This accounting estimate is reasonably likely to change from period to period as further stock options are issued and adjustments are made for stock option forfeitures and cancellations. We make an estimate for stock option forfeitures at the time of grant and revise this estimate in subsequent periods if actual forfeitures differ. The term "forfeitures" is distinct from "cancellations" or "expirations" and represents only the unvested portion of the surrendered stock option. Prior to Q2 2014, for the purpose of calculating the fair value, the expected life of stock options granted was eight years for employees, and ten years for directors and executives. Based on the pattern of increasing exercises of stock options, we have reduced the expected life to five years for employees and eight years for directors and executives for stock options granted after March 31, 2014. The expected life and fair values of stock-options granted prior to this date remain unchanged. The reduction in expected life has the effect of reducing the fair value of stock-options granted. We amortize the fair value of stock options using the straight-line method over the vesting period of the options, generally a period of three years for employees and immediate vesting for directors.
 
We recorded stock-based compensation expense in 2014 of $3.3 million (2013 - $0.9 million, 2012 - $1.0 million). The impact on the fair value of stock options due to the reduction in expected life is minor, as we would have recorded stock-based compensation expense of $3.4 million in 2014 using the previous expected life assumptions of eight and ten years for employees and directors and executives, respectively.
 
Share purchase warrant valuation / The valuation of share purchase warrants is a critical accounting estimate due to the value of liabilities recorded and the many assumptions that are required to calculate the liability, resulting in the classification of our warrant liability as a level 3 financial instrument.
 
We classify warrants in our consolidated balance sheet as liabilities and revalue them at each balance sheet date. Any change in valuation is recorded in our statement of operations. We use the Black-Scholes pricing model to value the warrants. Determining the appropriate fair-value model and calculating the fair value of registered warrants requires considerable judgment. A small change in the estimates used may cause a relatively large change in the estimated valuation. Due to ongoing changes in our business and general stock market conditions, we continuously assess our warrant fair value assumptions. We adjust the estimated expected life as appropriate, based on the pattern of exercises of our warrants. Our expected volatility is calculated based on our historic share price fluctuations over the same period as our estimated expected life of our outstanding warrants. The risk-free interest rate is based on the Government of Canada rate for bonds with a maturity similar to the expected remaining life of the warrants at the valuation date.
  
We recorded a loss for the change in fair value of warrant liability in 2014 of $10.4 million (2013 – loss of $3.5 million, 2012 – loss of $3.8 million).

Financial instrument valuation / The valuation of our financial instrument, which is Monsanto’s option to acquire either the shares or assets of Protiva Agricultural Development Company Inc., is a critical accounting estimate due to the potential value of the liability and the many assumptions we must make to calculate the fair value of the liability.

We classify the financial instrument in our consolidated balance sheet as a liability and revalue it at each balance sheet date. Any change in the valuation is recorded in our statement of operations. We used a discounted cash flow model to value the financial instrument. Determining the appropriate fair value model and calculating the fair value of the financial instrument requires considerable judgment, and changes in assumptions used may cause a relatively large change in the estimated valuation. The initial valuation of the financial instrument was determined to be nil. No change in the fair value of the financial instrument was recorded as at December 31, 2014.

Quarterly Trends
 
Revenue / Our revenue is derived from research and development collaborations and contracts, licensing fees, milestone and royalty payments. Over the past two years, our principal source of ongoing revenue has been our contract with the DoD to advance TKM-Ebola which began in July 2010. We expect revenue to continue to fluctuate particularly due to the development stage of the TKM-Ebola contract and the irregular nature of licensing and milestone receipts.
 
In Q3 2010 we signed a contract with the DoD to develop TKM-Ebola and have since incurred significant program costs related to equipment, materials and preclinical and clinical studies. These costs are included in our research, development, collaborations and contracts expenses. These costs are fully reimbursed by the DoD, and this reimbursement amount is recorded as revenue. DoD revenue from the TKM-Ebola program also compensates us for labor and overheads and provides an incentive fee. As described in our critical accounting policies, we estimate the labor and overhead rates to be charged under our TKM-Ebola contract and update these rate estimates throughout the year. Q1 2013 DoD revenue was lower as certain activities were still building momentum following the stop-work order that occurred in Q3 2012. TKM-Ebola contract revenue increased in Q2, Q3 and Q4 2013 as technology transfer, manufacturing and non-clinical studies were all ongoing. In April 2014, we signed a contract modification to increase the stage one targeted funding by $2.1 million to $43.8 million. The additional funding is to compensate us for unrecovered costs related to the temporary stop-work period that occurred in 2012 and to provide additional overhead funding should it be required. In Q2 2014, we earned $3.2 million in DoD revenue, due partially to an increase in activity as we moved into a Phase I Clinical Trial. Also, as a result of the contract modification, we now expect to complete the initial stage of the contract close to budget, which increases our estimate of total incentive fee to be earned under the contract and the amount we have earned to date. In Q2 2014, we earned $0.9 million in DoD revenue due to lower contract activity as our clinical trial data was with the FDA for review. DoD revenue increased in Q3 2014 with an increase in activity as we prepared a response to the FDA’s partial clinical hold on our Phase I Clinical Trial. In October 2014, the DoD exercised a contract option adding $7.0 million to the contract for the scale-up and manufacture of TKM-Ebola-Guinea, our product targeting the Ebola-Guinea strain responsible for the current outbreak in West Africa. DoD revenue increased in Q4 2014 to $2.8 million as we purchased materials for the manufacture of TKM-Ebola-Guinea.

In January 2014, we signed an Option Agreement and a Services Agreement with Monsanto for the use of our proprietary delivery technology and related intellectual property in agriculture. Over the option period, which is expected to be approximately four years, Monsanto will make payments to us to maintain their option rights. In Q1 2014, we received $14.5 million of the $17.5 million near term payments, of which $4.5 million relates to research services and $10.0 million for the use of our technology. In June 2014 and October 2014, we received further payments of $1.5 million each, following the completion of specified program developments. The payments are being recognized as revenue on a straight-line basis over the option period.

In November 2014, we signed a License Agreement and a Development and Supply Agreement with Dicerna for the use of our proprietary delivery technology and related technology intended to develop, manufacture, and commercialize products related to treatment of PH1. In Q4 2014, we received an upfront payment of $2.5 million, which is being recognized over the period over which we provide services to Dicerna, estimated to complete in Q1 2017.

In Q4 2013 we earned a $5.0 million milestone from Alnylam following their initiation of a Phase III trial enabled by our LNP technology.
 
In Q4 2013, we began to earn royalties from Spectrum with respect to the commercial sales of Marqibo.

Included in “other collaborations and contract revenue” is revenue from a BMS batch formulation agreement. In Q4 2013, we offered to extend the BMS agreement end date from May 2014 to December 2014. Extending the agreement would have given BMS more time to order LNP batches. Revenue recognized in 2013 has been reduced and the balance of deferred revenue as at December 31, 2013 has been increased to account for BMS potentially ordering more batches under the agreement. This agreement is reflected in the $0.1 million of negative “other revenue” in Q4 2013 when the offer was made to extend the agreement and a cumulative revenue adjustment was recorded. In August 2014, we received notification from BMS that the extension would not occur. As such, the collaboration expired and both parties’ obligations under the agreement ended. Revenue recognized in Q3 2014 relates to the release of the deferred revenue balance of $1.6 million.

Expenses / Expenses consist primarily of clinical and pre-clinical trial expenses, personnel expenses, consulting and third party expenses, reimbursable collaboration expenses, consumables and materials, patent filing expenses, facilities, stock-based compensation and general corporate costs.
 
Our expenses have increased in the past eight quarters due to an increase in our research and development activities as we seek to move more products into the clinic. In Q3 2013, we initiated a Phase I/II Clinical Trial for TKM-PLK1 in patients with GI-NET or ACC. In Q1 2014, we dosed the first subject in human clinical trials of TKM-Ebola. In Q2 2014, we initiated a Phase I/II Clinical Trial for TKM-PLK1 in patients with HCC. In Q4 2014, we filed a Canadian Clinical Trial Application (CTA) for TKM-HBV and received clearance to conduct a Phase I Clinical Trial, as well as initiated manufacturing of TKM-Ebola-Guinea for emergency use in West Africa – see overview. We also incurred research and development expenses related to identifying new targets.
 
Other income (losses) / Other income (losses) consist primarily of changes in the fair value of our warrant liability and foreign exchange differences. Other losses increased in Q3 2013, Q1 2014, and Q3 2014 due primarily to the increase in fair value of our warrant liability. Increases in our share price from the previous reporting date result in an increase in the fair value of our warrant liability, and vice versa. We expect to see future changes in the fair value of our warrant liability and these changes will largely depend on the change in the Company’s share price, any change in our assumed rate of share price volatility, our assumptions for the expected lives of the warrants and warrant exercises.
 
Net loss / Fluctuations in our net loss are explained by changes in revenue, expenses and other income (losses) as discussed above.
 
Fourth quarter of 2014 / Our Q4 2014 net loss was $6.2 million ($0.27 basic and diluted loss per common share) as compared to a net loss of $2.6 million ($0.15 basic and diluted loss per common share) for Q4 2013.
 
Revenue was $4.6 million in Q4 2014 as compared to $7.6 million in Q4 2013. The decrease was largely due to the $5.0 million milestone payment from Alnylam received in Q4 2013.
 
Research, development, collaborations and contracts expenses increased to $11.9 million in Q4 2014 as compared to $7.0 million in Q4 2013. In Q4 2014, we increased research and development activities related to moving TKM-HBV into the clinic, including costs incurred in preparing a CTA, as well as costs incurred to support the ongoing HCC Phase I clinical trial for TKM-PLK1. Further, in Q4 2014, we purchased materials for the manufacture of TKM-Ebola-Guinea for use in West Africa – see overview.
 
 
51

 
Other losses in Q4 2013 primarily consists of $1.4 million increase in warrant liability due to the increase in our share price, and a foreign exchange gain of $1.1 million on our US dollar funds. Other gains in Q4 2014 primarily consist of a $2.6 million decrease in the fair value of our warrant liability, and a foreign exchange gain of $2.3 million on US dollar funds. We also incurred $0.5 million in acquisition costs related to the merger with OnCore in Q1 2015 – see overview.

DoD revenue
 
On July 14, 2010, we signed a contract with the United States Government Department of Defense (“DoD”) to advance an RNAi therapeutic utilizing our LNP technology to treat Ebola virus infection (see Overview for further discussion). The initial phase of the contract was budgeted at $34.7 million.  This stage one funding is for the development of TKM-Ebola, including, completion of preclinical development, filing an IND application with the FDA and completing a Phase I human safety clinical trial. The DoD has the option of extending the contract beyond the initial funding period to support the advancement of TKM-Ebola through to the completion of clinical development and FDA approval. Based on the contract’s budget, this would provide the Company with up to $140 million in funding for the entire program.
 
In November 2012, we submitted a modification request to the existing contract to the DoD in order to integrate recent advancements in LNP formulation and manufacturing technology in the TKM-Ebola development program. The modification was approved and increased the stage one targeted funding from $34.7 million to $41.7 million. In April 2014, we signed a contract modification with the DoD to increase the stage one targeted funding by a further $2.1 million to $43.8 million. The additional funding is to compensate us for unrecovered costs incurred related to the temporary stop-work period that occurred in 2012 and to provide additional overhead funding should it be required. In October 2014, the DoD exercised an option valued at $7.0 million, awarded to us to manufacture TKM-Ebola-Guinea targeting the Ebola-Guinea strain responsible for the current outbreak in West Africa.
 
 
52

 
Under the contract, we are being reimbursed for costs incurred, including an allocation of overheads, and we are being paid an incentive fee.

DoD revenues and related contract expenses were lower in 2014 as compared to 2013 as we are nearing the end of stage one of the contract so most activities for this stage have already been completed. The reduction in stage one revenue in 2014 was offset by the addition of the $7.0 million award for the manufacture of TKM-Ebola-Guinea towards the end of 2014.
 
Monsanto revenue

On January 13, 2014, we signed an Option Agreement and a Services Agreement (together, the “Agreements”) with Monsanto. Under the Agreements, Monsanto has an option to acquire a license to use our proprietary delivery technology and related intellectual property for use in agriculture. Over the option period, which is expected to be approximately four years, we will provide lipid formulations for Monsanto’s research and development activities, and Monsanto will make certain payments to us to maintain their option rights (see Overview for further discussion).

In January 2014, we received $14.5 million, of which $4.5 million relates to research services and $10.0 million for the use of our technology, In June and September 2014, we received payments of $1.5 million each, following the completion of specified program developments. We are recognizing this revenue on a straight-line basis over the option period. For the year-ended December 31, 2014, we have recorded an aggregate of $3.8 million in revenue for the use of our technology and for research activities.

Alnylam and Acuitas revenue
 
On November 12, 2012, we entered into a new licensing agreement with Alnylam that replaces all earlier licensing, cross-licensing, collaboration, and manufacturing agreements. We also entered into a separate cross license agreement with Acuitas, which includes milestones and royalty payments, and Acuitas has agreed not to compete in the RNAi field for five years.
 
In November 2013, Alnylam initiated a Phase III trial with ALN-TTR02, also known as patisiran, and an associated $5.0 million development milestone was paid to us in December 2013. In March 2014, we earned a $0.15 milestone payment from Acuitas following their receipt of a milestone from Alnylam with the initiation of the ALN-TTR02 Phase III trial.

On June 21, 2013, we transferred manufacturing process technology to Ascletis to enable them to produce ALN-VSP, a product candidate licensed to them by Alnylam. We believe that under our licensing agreement with Alnylam, the technology transfer to Ascletis triggers a $5.0 million milestone obligation from Alnylam to us. However, Alnylam has demanded a declaration that we have not yet met its milestone obligations. We dispute Alnylam’s position. To remedy this dispute, we have commenced arbitration proceedings with Alnylam, as provided for under the agreement. The hearing date for this arbitration is currently set for the second week in May, 2015.   We have not recorded any revenue in respect of this milestone.
 
BMS revenue
 
In May 2010 we signed a formulation agreement with BMS under which BMS paid us $3.0 million to make a certain number of LNP formulations over the following four year period. Revenue recognized in 2012 and 2013 relate to LNP batches the company produced in proportion to the maximum LNP formulations that may be required under the contract. As at December 31, 2013, we intended to offer BMS an extension to the agreement’s end date from May 10, 2014 to December 31, 2014. Extending the agreement would have given BMS more time to order LNP batches. The offer of extension resulted in a cumulative revenue adjustment recorded for the year-ended December 31, 2013. In August 2014, we received notification from BMS that the extension would not occur. Revenue recognized for the year-ended December 31, 2014 relates to the batches shipped to BMS during the period and the release of any remaining deferred revenue balance now that the agreement has expired and no further obligation with either party.

Dicerna revenue
 
In November 2014, we signed a License Agreement and a Development and Supply Agreement with Dicerna for the use of our proprietary delivery technology and related technology intended to develop, manufacture, and commercialize products related to treatment of PH1. Revenue recognized for the year-ended December 31, 2014 relates to the earned portion of the upfront payment of $2.5 million for the use our of technology, which is being recognized over the period over which we provide services to Dicerna, estimated to complete in March 2017.
 
Spectrum revenue
 
In September 2013, Spectrum announced that they had shipped the first commercial orders of Marqibo. For the year-ended December 31, 2014, we earned royalties of $0.2 million on the sales of Marqibo, which uses a license to our technology.
