Overview

We are a clinical-stage, oncology therapeutics company, taking a Precision Cancer Medicine™ (PCM) approach to develop drugs that target mitosis (cell division) for the treatment of various cancers including prostate, colorectal and leukemia.  By integrating a biomarker strategy into our development programs, we will be able to identify patients more likely to respond to treatment.

On March 15, 2017, we announced that we licensed onvansertib, a PLK1 inhibitor, from Nerviano, pursuant to a license agreement with Nerviano dated March 13, 2017. This exclusive, world-wide license agreement includes 3 issued patents for onvansertib which cover composition of matter, salt forms of onvansertib and combination of onvansertib with other drugs. Onvansertib was developed to have high selectivity to PLK1 (at low nanomolar IC50 levels), to have ideal pharmacokinetics, including oral bioavailability and administration and a drug half-life of approximately 24 hours, allowing for flexible dosing and scheduling, and is well tolerated and safe with only mild- to moderate side effects reported to-date. A Phase 1 safety study of onvansertib has been successfully completed in patients with advanced metastatic solid tumors and published in 2017 in Investigational New Drugs. We currently have three active clinical trials: a Phase 2 open-label clinical trial of onvansertib in combination with abiraterone acetate (Zytiga®) and prednisone in patients with metastatic Castration-Resistant Prostate Cancer (“mCRPC”), being conducted at Beth Israel Deaconess Medical Center (“BIDMC”), Dana-Farber Cancer Institute (“DFCI”), and Massachusetts General Hospital (“MGH”); a Phase 1b/2 open-label clinical trial of onvansertib in combination with FOLFIRI and Avastin® in patients with mCRC with a KRAS mutation, being conducted at USC Norris Comprehensive Cancer Center and The Mayo Clinic; and a Phase 1b/2 open-label clinical trial of onvansertib in combination with standard-of-care chemotherapy in patients with AML, being conducted at eight sites across the U.S.

Onvansertib is a first-in-class, third-generation, oral and highly-selective PLK1 inhibitor with demonstrated antitumor activity in different preclinical models. Polo-like kinase family consists of 5 members (PLK1-PLK5) and they are involved in multiple functions in cell division, including the regulation of centrosome maturation, checkpoint recovery, spindle assembly, cytokinesis, apoptosis and many others. PLK1 is essential for the maintenance of genomic stability during cell division. The over-expression of PLK1 can lead to immature cell division followed by aneuploidy and cell death, a hallmark of cancer. PLK1 is over-expressed in a wide variety of leukemias/lymphomas and solid tumor cancers, including acute myeloid leukemia, non-Hodgkin lymphoma, prostate, lung, breast, ovarian, colorectal and adrenocortical carcinoma. In addition, several studies have shown that over-expression of PLK1 is associated with poor prognosis. Blocking the expression of PLK1 by kinase inhibitors, such as onvansertib, can effectively inhibit growth of, and induce, tumor cell death.

Studies have shown that inhibition of polo-like-kinases can lead to tumor cell death, including a Phase 2 study in Acute Myeloid Leukemia (“AML”) where response rates with a prior PLK inhibitor of up to 31% were observed when used in conjunction with a standard therapy for AML (low-dose cytarabine (“LDAC”)) versus a 13.3% response rate with LDAC alone. We believe the more selective nature of onvansertib to PLK1, its 24-hour half-life and oral bioavailability, as well as its demonstrated safety and tolerability, with only mild- to moderate side effects reported, may prove useful in addressing clinical therapeutic needs across a variety of cancers.

1

Onvansertib has been tested in-vivo in different xenograft and transgenic models suggesting tumor growth inhibition or tumor regression when used in combination with other therapies. Onvansertib has been tested for antiproliferative activity on a panel of 148 tumor cell lines and appeared highly active with an IC50 (a measure concentration for 50% target inhibition) below 100 nM in 75 cell lines and IC50 values below 1 uM in 133 out of 148 cell lines. Onvansertib also appears active in cells expressing multi-drug resistant (“MDR”) transporter proteins and we believe its apparent ability to overcome the MDR transporter resistance mechanism in cancer cells could prove useful in broader drug combination applications.

In in-vitro and in-vivo preclinical studies, synergy (interaction of discrete drugs such that the total effect is greater than the sum of the individual effects) has been demonstrated with onvansertib when used in combination with numerous different chemotherapies, including cisplatin, cytarabine, doxorubicin, gemcitabine and paclitaxel, as well as targeted therapeutics, such as abiraterone acetate (Zytiga®), histone deacetylase (“HDAC”) inhibitors, such as belinostat (Beleodaq®), quizartinib (AC220), a development stage FLT3 inhibitor, and bortezomib (Velcade®). These therapies are used clinically for the treatment of leukemias, lymphomas and solid tumor cancers, including AML, Non-Hodgkin Lymphoma (“NHL”), mCRPC, mCRC, and Triple Negative Breast Cancer (“TNBC”).

We continue to focus on advancing our three active clinical trials with onvansertib in 2019. We have achieved a number of key milestones through the first three quarters of 2019 and anticipate achieving  additional milestones through the end of 2019:

Phase 1b/2 Trial of Onvansertib in Combination with Either Low-Dose Cytarabine or Decitabine for theTreatment of Acute Myeloid Leukemia

·Completed Phase 1b dose escalation safety segment of trial, identified the  recommended Phase 2 dose (“RP2D”) of onvansertib at 60mg/m2.

·Initiated the Phase 2 segment of the AML trial, which will enroll approximately 32 patients, for continued evaluation of safety and efficacy of onvansertib in combination with decitabine.

·Provide safety and preliminary efficacy data on the combination of onvansertib in combination with decitabine in patients treated through the end of 2019.

·Present data from the AML trial at key oncology conferences, including the European Society for Medical Oncology (“ESMO”) and the American Society of Hematology (“ASH”) annual meetings.

Phase 2 Trial of Onvansertib in Combination with Abiraterone Acetate (Zytiga®) and Prednisone for the Treatment of Metastatic Castration-Resistant Prostate Cancer

·Completed enrollment and evaluation of the 6 safety lead-in patients in the second arm (2-week dosing schedule) with onvansertib at 24 mg/m2 in combination with abiraterone acetate (Zytiga®) and prednisone.

·Provide safety and preliminary efficacy data of onvansertib in combination with abiraterone acetate (Zytiga®) and prednisone in patients treated through the end of 2019.

·Present data from the mCRPC trial at key oncology conferences throughout 2019, including the Asia-Pacific Prostate Cancer Conference (“APPC”), and first quarter of 2020 including ASCO-GU.

Phase 1b/2 Trial of Onvansertib in Combination with FOLFIRI and Bevacizumab (Avastin®) for Second-Line Treatment of Metastatic Colorectal Cancer with a KRAS Mutation

·Completed enrollment and evaluation of the initial dose level cohort of onvansertib 12 mg/m2 and opened the second dose level (onvansertib 15 mg/m2) cohort to enrollment.

2

·Provide safety and preliminary efficacy data on the combination of onvnasertib + FOLFIRI + Avastin® in patients treated through the end of 2019.

During 2019, we have advanced our business with the following activities:

·Announced positive response to treatment in Phase 1b/2 trial of onvansertib in patients with KRAS-mutated metastatic colorectal cancer.

On October 22, 2019, we announced data demonstrating positive response to treatment in patients enrolled in its Phase 1b/2 trial of onvansertib in combination with FOLFIRI and Avastin® (bevacizumab) for second-line treatment of KRAS-mutated metastatic colorectal cancer (mCRC). Decreases in tumor KRAS mutational burden in response to treatment was observed in all four patients who completed their first cycle of therapy with the combination regimen, as measured by quantitative analysis of circulating tumor DNA (ctDNA).

·Announced data presented at ESMO providing rationale for a clinical trial of onvansertib in subset of patients with Highly-Aggressive Triple Negative Breast Cancer (TNBC).

On October 2, 2019, we announced the presentation of data in a poster at ESMO demonstrating significant tumor regression observed with onvansertib in combination with standard-of-care paclitaxel in models of p53-mutated TNBC. Onvansertib preclinical data provides rationale for conducting a clinical trial targeting the 80% of TNBC that harbors the p53 mutation. The combination has potential to address critical medical need to provide targeted treatment option to overcome resistance to paclitaxel as single agent therapy in TNBC.

·Announced presentation of a poster at ESMO of Phase 1b/2 trial of onvansertib in patients with KRAS-mutated metastatic colorectal cancer (mCRC).

On October 1, 2019, we announced the presentation of a poster at ESMO providing an overview of our  Phase 1b/2 trial in metastatic Colorectal Cancer, to assess the safety and efficacy of onvansertib in combination with FOLFIRI and Avastin® (bevacizumab) in KRAS-mutated mCRC. Approximately 50% of patients harbor the KRAS mutation; current standard-of-care therapy has only a 5% response rate. Biomarker data demonstrates ability to assess patient response to therapy within one week of treatment with onvansertib.

·Announced Oral Presentation of Positive Data from Trovagene Phase 1b/2 Study of Onvansertib at ESMO Conference.

On September 30, 2019, we announced positive data from our Phase 1b/2 trial in acute myeloid leukemia (AML) was presented in an oral plenary session at the ESMO conference. The data showed that administration of onvansertib in combination with standard-of-care chemotherapy is safe and well-tolerated and resulted in anti-leukemic activity that appears to be sustainable over time. There is a strong correlation between biomarker positive patients and treatment response; observed in 6 of 9 biomarker positive patients versus 1 of 11 biomarker negative patients. Phase 2 is open to enrolling 32 patients for treatment with onvansertib at the recommended dose of 60 mg/m², in combination with decitabine, to further assess safety and efficacy of the regimen.

·Announced Successful Completion of the AML Phase 1b Trial and Initiation of the Phase 2 Continuation Trial.

3

On September 19, 2019, we announced the successful completion of our Phase 1b trial in acute myeloid leukemia (AML) and the initiation of patient enrollment in Phase 2. The Phase 1b dose escalation clinical trial confirmed safety, preliminary efficacy and identified the recommended phase 2 dose of onvansertib. Complete response (CR + CRi) was achieved in 5 of 21 patients treated with onvansertib in combination with decitabine. Phase 2 will treat 32 patients with onvansertib + decitabine; eligible patients will have relapsed after receiving up to one prior therapy including patients who have developed resistance to first-line treatment with venetoclax.

·Announced the Presentation of Positive Clinical Data from Ongoing Phase 2 Study of Onvansertib in Metastatic Castration-Resistant Prostate Cancer (mCRPC) at the Asia-Pacific Prostate Cancer Conference.

On August 26, 2019, we announced findings from our Phase 2 trial in metastatic Castration-Resistant Prosate Cancer (mCRPC) trial leads to the discovery that onvansertib stops the rise in PSA in patients with treatment-resistant, highly-aggressive and difficult-to-treat androgen-receptor variant 7 (AR-V7) tumors. Data demonstrates efficacy of onvansertib in patients showing early signs of resistance to androgen receptor signaling (ARS) inhibitor, Zytiga®. The addition of onvansertib appears to extend the duration of response to ARS inhibitor therapy in this incurable and lethal cancer.

·Announced research collaboration with Nektar Therapeutics to evaluate the efficacy of the combination of onvansertib and ONZEALDTM in models of colorectal cancer.

On May 23, 2019, we announced we entered into a research collaboration agreement with Nektar Therapeutics to explore the combination of our PLK1 inhibitor, onvansertib, and Nektar’s topoisomerase I inhibitor, ONZEALD, for the treatment of mCRC. Under the collaboration, the two companies will evaluate the antitumor activity and tolerability of the combination of onvansertib and ONZEALD in two(HT29 - BRAF mutant and HCT-116 - KRAS mutant) preclinical tumor models of colorectal cancer.

·Announced Data Demonstrating Significant Synergy of Onvansertib in Combination with Venetoclax in Cell Model of Venetoclax-Resistant AML.

On April 23, 2019, we announced preclinical data that evaluated the effect of combining onvansertib with venetoclax in an AML cell model known to be resistant to venetoclax (Venclexta® - AbbVie). This combination demonstrated synergy (the combined effect of the two drugs is greater than the sum of their individual effects) with a significant decrease in tumor cell viability. This data provides support for clinical evaluation of onvansertib in combination with venetoclax in patients with difficult-to-treat relapsed/refractory AML, for which there are limited treatment options and the prognosis is poor.

·Announced New Patent Issued for Combination of Onvansertib with Anti-Androgen Drugs to Treat Non-Metastatic and Metastatic Prostate Cancer.

On January 23, 2019, we announced the issuance of a new patent (10,155,006), entitled Combination Therapies and Methods of Use Thereof for Treating Cancer, by the U.S. Patent and Trademark Office (“USPTO”). This patent broadens previously issued patent (9,566,280), by expanding the use of onvansertib to encompass combination therapies with any anti-androgen and androgen antagonist drug, such as Zytiga®, Xtandi® and Erleada® for the treatment of metastatic and non-metastatic castrate-resistant prostate cancer.

Dividends are payable, at our sole election, in cash or shares of Common Stock. As of December 31, 2018 and 2017, we had $341,015 and $316,775, respectively in accrued cumulative unpaid preferred stock dividends, included in accrued liabilities in our consolidated balance sheets, and $24,240 and $24,240 of accrued dividends was recorded during the years ended December 31, 2018 and 2017, respectively.

Voting Rights. Shares of the Series A Convertible Preferred Stock have no voting rights. However, so long as any shares of Series A Convertible Preferred Stock are outstanding, we may not, without the affirmative vote of the holders of the shares of Series A Convertible Preferred Stock then outstanding, (a) adversely change the powers, preferences or rights given to the Series A Convertible Preferred Stock, (b) authorize or create any class of stock senior or equal to the Series A Convertible Preferred Stock, (c) amend its certificate of incorporation or other charter documents, so as to affect adversely any rights of the holders of Series A Convertible Preferred Stock or (d) increase the authorized number of shares of Series A Convertible Preferred Stock.

Liquidation. Upon any liquidation, dissolution or winding-up of our company, the holders of the Series A Convertible Preferred Stock are entitled to receive an amount equal to the Stated Value per share, which is currently $10 per share plus any accrued and unpaid dividends.

Conversion Rights. Each share of Series A Convertible Preferred Stock is convertible at the option of the holder into that number of shares of Common Stock determined by dividing the Stated Value, currently $10 per share, by the conversion price, which at the time of issuance was $928.80 per share.

Subsequent Equity Sales. The conversion price is subject to adjustment for dilutive issuances for a period of 12 months beginning upon registration of the Common Stock underlying the Series A Convertible Preferred Stock. The relevant registration statement became effective on March 17, 2006 and the conversion price was adjusted to $691.20 per share.

Automatic Conversion.   If the price of our Common Stock equals $1,857.60 per share for 20 consecutive trading days, and an average of 116 shares of Common Stock per day are traded during the 20 trading days, we will have the right to deliver a notice to the holders of the Series A Convertible Preferred Stock, requesting the holders to convert any portion of the shares of Series A Convertible Preferred Stock into shares of Common Stock at the applicable conversion price.

Anti-Takeover Effects of Certain Provisions of our Certificate of Incorporation, Bylaws and the DGCL

Delaware Law

We are subject to Section 203 of the Delaware General Corporation Law. This provision generally prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date the stockholder became an interested stockholder, unless:

·prior to such date, the board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

·upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding those shares owned by persons who are directors and also officers and by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

·on or subsequent to such date, the business combination is approved by the board of directors and authorized at an annual meeting or special meeting of stockholders and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

Section 203 defines a business combination to include:

·any merger or consolidation involving the corporation and the interested stockholder;

·any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder;

·subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;

·any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; or

11

·the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.

In general, Section 203 defines an “interested stockholder” as any entity or person beneficially owning 15% or more of the outstanding voting stock of a corporation, or an affiliate or associate of the corporation and was the owner of 15% or more of the outstanding voting stock of a corporation at any time within three years prior to the time of determination of interested stockholder status; and any entity or person affiliated with or controlling or controlled by such entity or person.

These statutory provisions could delay or frustrate the removal of incumbent directors or a change in control of our Company. They could also discourage, impede, or prevent a merger, tender offer, or proxy contest, even if such event would be favorable to the interests of stockholders.

Our amended and restated certificate of incorporation and bylaws contain provisions that could have the effect of discouraging potential acquisition proposals or making a tender offer or delaying or preventing a change in control, including changes a stockholder might consider favorable. In particular, our certificate of incorporation and bylaws, as applicable, among other things:

·provide our board of directors with the ability to alter our bylaws without stockholder approval; and

·provide that vacancies on our board of directors may be filled by a majority of directors in office, although less than a quorum.

Such provisions may have the effect of discouraging a third-party from acquiring us, even if doing so would be beneficial to our stockholders. These provisions are intended to enhance the likelihood of continuity and stability in the composition of our board of directors and in the policies formulated by them, and to discourage some types of transactions that may involve an actual or threatened change in control of our Company. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal and to discourage some tactics that may be used in proxy fights. We believe that the benefits of increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure our Company outweigh the disadvantages of discouraging such proposals because, among other things, negotiation of such proposals could result in an improvement of their terms.

However, these provisions could have the effect of discouraging others from making tender offers for our shares that could result from actual or rumored takeover attempts. These provisions also may have the effect of preventing changes in our management.

Disclosure of SEC Position on Indemnification for Securities Act Liabilities

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended (the “Securities Act”), may be permitted for directors, officers and persons controlling our Company, we understand that it is the SEC’s opinion that such indemnification is against public policy as expressed in the Securities Act and may therefore be unenforceable.

PLAN OF DISTRIBUTION

The selling security holders, including their transferees, donees, pledgees, assignees and successors-in-interest, may, from time to time, sell, transfer or otherwise dispose of any or all of the shares of common stock offered by this prospectus from time to time on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at market prices prevailing at the time of sale, at prices related to prevailing market price, at varying prices determined at the time of sale or at negotiated prices. The selling security holders may use any one or more of the following methods when selling shares:

·ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

·block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

·purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

·an exchange distribution in accordance with the rules of the applicable exchange;

·privately negotiated transactions;

·settlement of short sales entered into after the date of this prospectus;

·broker-dealers may agree with the selling security holders to sell a specified number of the shares at a stipulated price per share;

·through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

·a combination of any of these methods of sale; or

·any other method permitted pursuant to applicable law.

The selling security holders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus.

Broker-dealers engaged by the selling security holders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling security holders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. Each selling security holder does not expect these commissions and discounts relating to its sales of shares to exceed what is customary in the types of transactions involved.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the shares may not simultaneously engage in market making activities with respect to our common stock for a period of two business days prior to the commencement of the distribution. In addition, the selling security holders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of shares of our common stock by the selling security holders or any other person. We have advised the selling security holders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the selling security holders and their affiliates. In addition, we will make copies of this prospectus available to the selling security holders for the purpose of satisfying the prospectus delivery requirements of the Securities Act and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale.

In connection with the sale of our common stock or interests therein, the selling security holders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling security holders may also sell

13

shares of our common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling security holders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to these broker-dealers or other financial institutions of shares offered by this prospectus, which shares these broker-dealers or other financial institutions may resell pursuant to this prospectus (as supplemented or amended to reflect these transactions).

The selling security holders and any broker-dealers or agents that are involved in selling the shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection with these sales. In this event, any commissions received by these broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each selling security holder has informed us that it does not have any agreement or understanding, directly or indirectly, with any person to distribute the common stock.

We are required to pay certain fees and expenses incurred by us incident to the registration of the shares. We have agreed to indemnify the selling security holders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

The selling security holders may agree to indemnify any agent, dealer or broker-dealer that participates in transactions involving sales of the shares against certain liabilities, including liabilities arising under the Securities Act.

Because selling security holders may be deemed to be “underwriters” within the meaning of the Securities Act, they will be subject to the prospectus delivery requirements of the Securities Act. In addition, any securities covered by this prospectus which qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than under this prospectus. There is no underwriter or coordinating broker acting in connection with the proposed sale of the shares by the selling security holders.

We have agreed with the selling stockholders to keep the registration statement of which this prospectus forms a part effective until the earlier of (1) the date on which all the shares have been sold thereunder or pursuant to Rule 144 or (2) the date on which all of the shares may be sold without restriction pursuant to Rule 144 of the Securities Act.
