Introduction-Forward Looking Statements

This Annual Report on Form 10-K contains “forward-looking statements” as defined by the Private Securities Litigation Reform Act of 1995. These forward-looking statements involve risks and uncertainties including uncertainties associated with timely development, approval, launch and acceptance of new products, satisfactory completion of clinical studies, establishment of new corporate alliances, progress in research and development programs and other risks and uncertainties described below under the headings “Our Lead Product Candidate APF530”, “Development Pipeline”, “Our Technology Platform”, “Our Strategy”, “Patents and Trade Secrets”, and “Competition”. Such risks and uncertainties also include the matters discussed under “Risk Factors” below, and under Management’s Discussion and Analysis of Financial Condition and Results of Operations in Item 7 below.

Company Overview

In this Annual Report on Form 10-K, the “Company”, “A.P. Pharma”, “we”, “us”, and “our”, refer to A.P. Pharma, Inc.

We are a specialty pharmaceutical company focused on developing pharmaceutical products using our proprietary Biochronomer polymer-based drug delivery technology. Our product development philosophy is based on incorporating approved therapeutics into our proprietary bioerodible drug delivery technology to create controlled release pharmaceuticals to improve treatments for diseases or conditions. Our lead product candidate, APF530, is currently in a pivotal Phase III clinical trial for the prevention of acute and delayed onset chemotherapy-induced nausea and vomiting, or CINV. We expect to complete enrollment of our pivotal Phase III clinical trial in the second quarter of 2008 and to announce results of that trial in the third quarter of 2008. We expect to file our new drug application, or NDA, for approval of APF530 in the fourth quarter of 2008.

Our primary focus is to advance our proprietary Biochronomer technology, consisting of bioerodible polymers designed to release drugs over a defined period. We have completed over 100 in vivo and in vitro studies demonstrating that our Biochronomer technology is potentially applicable to a range of therapeutic areas, including prevention of nausea and vomiting, pain management, control of inflammation and treatment of ophthalmic diseases. We have also completed comprehensive animal and human toxicology studies that have established that our Biochronomer polymers are safe and well tolerated. Furthermore, our Biochronomer technology can be designed to deliver drugs over periods varying from days to several months.

Our lead product candidate, which utilizes our proprietary Biochronomer technology, is APF530. APF530 is designed to prevent CINV for at least five days and contains granisetron, a drug approved for the prevention of CINV. In September 2005, we completed a Phase II clinical trial of APF530 that achieved all of its primary and secondary endpoints. In May 2006, we initiated our pivotal Phase III clinical trial of AFP530. We believe that this clinical trial will lead to regulatory approval of APF530 for the prevention of acute and delayed onset CINV for patients undergoing both moderately and highly emetogenic chemotherapy.

In addition to our lead drug candidate, we have a pipeline of other product candidates that use our Biochronomer technology. One of these, APF112, incorporates the well-known local anesthetic, mepivacaine. It is designed to provide up to 36 hours of

post-surgical pain relief and to minimize the use of morphine-like drugs, or opiates, which are used extensively in post-surgical

3  •  A. P. PHARMA  •  2007 ANNUAL REPORT

pain management. Post-surgical pain can be treated with local anesthetics, but the usefulness of these is currently limited by the short duration of their effectiveness. We plan to initiate a Phase IIb clinical trial for APF112 in the second quarter of 2008.

We have several additional product candidates using our Biochronomer technology in early stages of development. For example, we plan to initiate a Phase I clinical trial of APF580 in the second quarter of 2008 for the controlled delivery of an opiate for pain relief.

We were founded in February 1983 as a California corporation under the name AMCO Polymerics, Inc. AMCO changed its name to Advanced Polymer Systems, Inc. in 1984 and was reincorporated in Delaware in 1987. We changed our name to A.P. Pharma, Inc. in May 2001 to reflect our new pharmaceutical focus. Our principal executive offices are located at 123 Saginaw Drive, Redwood City, California 94063. Our telephone number is (650) 366-2626. Our website is located at www.appharma.com. Information contained on, or that can be accessed through, our website is not part of this Annual Report on Form 10-K.

Our Lead Product Candidate—APF530

CINV Background

Prevention and control of nausea and vomiting, or emesis, are paramount in the treatment of cancer patients. The majority of patients receiving chemotherapy will experience some degree of emesis if not prevented with an antiemetic. Chemotherapy treatments can be classified as moderately emetogenic, meaning that 30 – 90% of patients experience CINV, or highly emetogenic, meaning that over 90% of patients experience CINV, if not prevented with an antiemetic. Acute onset CINV occurs within the first 24 hours following chemotherapy treatment. Delayed onset CINV occurs more than 24 hours after treatment and may persist for several days. Prevention of CINV is significant because the distress caused by CINV can severely disrupt patient quality of life and can lead some patients to discontinue chemotherapy. The unmet need is greatest with patients receiving highly emetogenic chemotherapy, particularly delayed onset CINV.

Current Therapy and Market Opportunity

Vomiting is a protective reflex against ingestion of potentially harmful substances, including some chemotherapeutic agents. These chemotherapeutic agents activate or destroy cells in the lining of the gut, releasing a neurotransmitter called serotonin. When serotonin binds to the 5-HT₃ (5-hydroxytryptamine type 3) receptors, the patient experiences nausea and vomiting. By blocking the 5-HT₃ receptors, granisetron and the other 5-HT₃ antagonists prevent serotonin from binding to the 5-HT₃ receptors, thereby inhibiting the vomiting reflex. Physicians may combine these 5-HT₃ antagonists with other agents, such as corticosteroids, to better prevent CINV.

Despite evidence that delayed onset CINV affects as many as 50 – 70% of patients, and that more patients experience delayed onset CINV than acute onset CINV, oncology nurses and physicians are likely to underestimate the magnitude of these problems in the patients for whom they care. According to the results of a multi-national study published in Cancer (April 2004), the discrepancy between the perceived incidence and the actual incidence may, in part, be due to the fact that patients often do not report the side effects they experience at home. In this prospective study, 60% of patients receiving highly emetogenic chemotherapy, who also received antiemetics, still had delayed onset CINV.

A. P. PHARMA  •  2007 ANNUAL REPORT  •  4

Current treatment options for CINV include 5-HT₃ antagonists such as palonosetron (Aloxi), ondansetron (Zofran), dolasetron (Anzemet), and granisetron (Kytril), as well as aprepitant (Emend), an NK1 (neurokinin-1) antagonist, which is always used in combination with a 5-HT₃ antagonist. As shown in the table below, all of the 5-HT₃ antagonists are approved for the prevention of acute onset CINV in patients receiving either moderately or highly emetogenic chemotherapy. Only Aloxi is approved for the prevention of delayed onset CINV in patients receiving moderately emetogenic chemotherapy. No 5-HT₃ antagonist is approved for the prevention of delayed onset CINV in patients receiving highly emetogenic chemotherapy. Aloxi sales were approximately $251 million in 2006 and $162 million for the first nine months of 2007. We believe the total addressable U. S. market approaches $1 billion for use of 5-HT₃ antagonists in the prevention of CINV.

Chemotherapy Regimen	Approved 5-HT3 Antagonists for Acute Onset CINV	Approved 5-HT3 Antagonists for Delayed Onset CINV
Moderately Emetogenic	Granisetron (Kytril) Ondansetron (Zofran) Dolasetron (Anzemet) Palonosetron (Aloxi)	Palonosetron (Aloxi)
Highly Emetogenic	Granisetron (Kytril) Ondansetron (Zofran) Dolasetron (Anzemet) Palonosetron (Aloxi)	NONE

Our Solution—APF530

Our lead product, APF530, is being developed for the prevention of both acute and delayed onset CINV in patients receiving either moderately or highly emetogenic chemotherapy. APF530 is delivered by a single subcutaneous injection and contains the 5-HT₃ antagonist, granisetron. Granisetron injections and oral tablets are approved for the prevention of acute onset CINV, but not delayed onset CINV. We selected granisetron because it is a potent drug and the applicable granisetron patent expired in the United States on December 29, 2007.

Granisetron and other 5-HT₃ antagonists, as a class, have become the most common antiemetic agents in chemotherapy. However, no 5-HT₃ antagonist formulation is currently approved for the prevention of both acute and delayed onset CINV for both moderately and highly emetogenic chemotherapy. We believe that if APF530 demonstrates that we can deliver therapeutic levels of granisetron over an extended period of time to prevent both acute and delayed onset CINV for both moderately and highly emetogenic chemotherapy, we will have a unique product with significant commercial potential. Physicians will have the opportunity to provide patients with the broadest efficacious treatment for CINV with a single injection.

Phase II Clinical Trial Results

In September 2005, we completed a Phase II clinical trial for APF530. We evaluated the safety, tolerability and pharmacokinetics of APF530 in cancer patients. In addition, efficacy endpoints were evaluated relating to emetic events and the use of additional medication for CINV. The clinical trial demonstrated that APF530 was well tolerated: there were no serious adverse events attributed to APF530; less than 10% of participating patients had injection site reactions, all of which were mild. As

5  •  A. P. PHARMA  •  2007 ANNUAL REPORT

shown in the graph below, the pharmacokinetic evaluation in all three dose groups (250, 500 and 750 mg injection doses corresponding to 5, 10 and 15 mg of granisetron, respectively) demonstrated that the target plasma levels of granisetron were substantially achieved. The target plasma levels were based on oral doses of granisetron shown to have exhibited efficacy for acute onset CINV.

Analysis of the efficacy data from our open-label Phase II trial in which patient groups received either moderately or highly emetogenic chemotherapy was based on complete responders. “Complete response” is defined as an absence of vomiting and no use of additional medication for CINV during the observation period.

A. P. PHARMA  •  2007 ANNUAL REPORT  •  6

Results of APF530’s Phase II trial and Aloxi’s Phase III trial are presented in the table below. Aloxi’s Phase III trials included two trials of 189 patients each for moderately emetogenic chemotherapy and one trial involving 223 patients for highly emetogenic chemotherapy. The two trials evaluating moderately emetogenic chemotherapy indicated that the percentage of complete responders was 81% and 63% in the acute phase and 74% and 54% in the delayed phase, respectively. The study evaluating highly emetogenic chemotherapy indicated that the percentage of complete responders was 59% in the acute phase and 45% in the delayed phase. In comparison, in our APF530 Phase II trial, 20 patients were treated and evaluated for moderately emetogenic chemotherapy; the percentage of complete responders among them was 90% in the acute phase and 78% in the delayed phase. 21 patients were treated and evaluated for highly emetogenic chemotherapy; the percentage of complete responders among them was 81% in the acute phase and 80% in the delayed phase. While these trials measure complete responders, there are inherent differences between the studies for the two products including, for example: phase of study, use of adjunct medications, presence of a control group, number of patients, blinded versus unblinded and study objectives.

Based on the data from the Aloxi Phase III trials and our own Phase II results, we designed our Phase III clinical program to conclusively compare APF530 to Aloxi in a prospective randomized design.

Pivotal Phase III Clinical Trial Design

In December 2005, we held our end-of-Phase-II meeting with the FDA, at which we discussed our regulatory approval strategy and our proposed design for the pivotal Phase III trial. Following this meeting, we designed our pivotal Phase III trial in accordance with FDA input. The trial’s primary objectives are to demonstrate:

•   non-inferiority of APF530 in comparison to Aloxi for the prevention of acute onset CINV following the administration of either moderately emetogenic or highly emetogenic chemotherapy;

•   non-inferiority of APF530 in comparison to Aloxi for the prevention of delayed onset CINV following administration of moderately emetogenic chemotherapy; and

•   superiority of APF530 in comparison to Aloxi for the prevention of delayed onset CINV following administration of highly emetogenic chemotherapy.

Based on our discussions with the FDA, we are planning to file our NDA under Section 505(b)(2) of the FDCA. Section 505(b)(2) of the FDCA permits the FDA, in its review of an NDA, to rely on previous FDA findings of safety and efficacy of the active ingredient in APF530, granisetron. The 505(b)(2) approval pathway is distinguished from the Abbreviated New Drug Application or generics route by the requirement that drug products approved under this section must have significant difference relative to the reference approved product. The additional information in the 505(b)(2) applications can be provided by literature or reference to past FDA findings of safety and efficacy for approved drugs, or it can be based upon studies conducted by or for the applicant to which it has obtained a right of reference. The majority of 505(b)(2) applications are filed for new formulations of currently approved drugs, so there is an existing understanding—on the part of the FDA, as well as the medical community—of their safety and efficacy.

Our pivotal Phase III clinical trial, initiated in May 2006, is a multicenter, randomized, observer-blind, actively-controlled, double-dummy, parallel group study that will compare the efficacy of APF530 with Aloxi. During 2006 and the first half of 2007, all patient enrollments were within the U.S.; beginning in the second half of 2007, enrollments were broadened to include sites in India and Poland. The trial will include approximately 1,350 patients, stratified in two groups, one receiving moderately and the other receiving highly emetogenic chemotherapeutic agents. In each group, the patients are randomized to receive in the first chemotherapy treatment cycle either APF530 high dose (10 mg), APF530 low dose (5 mg) or the currently approved dose of Aloxi. In subsequent treatment cycles (up to three additional cycles), the patients are re-randomized to either of the two APF530 doses. The diagram below provides further graphical representation of how patients are randomized in our clinical trial.

A. P. PHARMA  •  2007 ANNUAL REPORT  •  8

We expect to complete enrollment of our pivotal Phase III clinical trial in the second quarter of 2008 and to announce results of that trial in the third quarter of 2008. We expect to submit our NDA for approval of APF530 in the fourth quarter of 2008.

Market Survey

We commissioned Timely Data Resources, Inc., or TDR, to conduct market research to determine oncologists’ and oncology nurses’ perceptions of current antiemetics for CINV. This survey, completed in August 2006, was intended to assess the market opportunity for APF530 for the prevention of CINV. TDR interviewed 75 randomly selected medical oncologists and 25 oncology nurses from across the United States. The survey concluded that there is significant unmet need in the treatment of CINV, especially delayed onset CINV. 84% of the surveyed oncologists and oncology nurses currently use Aloxi and continue to have patients who experience CINV, particularly delayed onset CINV.

Development Pipeline

In addition to our lead program, we have a pipeline of other product candidates using our Biochronomer technology:

Product Candidate	Potential Application	Drug	Targeted Duration	Status
APF112	Post-surgical pain relief	Mepivacaine	Up to 36 hours	Phase II
APF580	Pain relief	Undisclosed Opiate	At least seven days	Preclinical
APF328	Local anti-inflammatory (orthopedic surgery)	Meloxicam	Up to two weeks	Preclinical
APF505	Anti-inflammatory (osteoarthritis)	Meloxicam	Up to six weeks	Preclinical

APF112

APF112 utilizes our Biochronomer delivery technology to target post-surgical pain relief. The product is designed to provide up to 36 hours of localized pain relief by delivering mepivacaine directly to the surgical site. Mepivacaine is a well-known, short- acting local anesthetic with an excellent safety profile. APF112 is designed to prolong the anesthetic effect of mepivacaine and thus to minimize or eliminate the use of opiates. Opiates are currently used in the majority of surgical procedures as a means of managing post-operative pain, and while they are powerful and useful drugs, they may have side effects such as addiction, nausea, disorientation, sedation, constipation, vomiting, urinary retention and, in some situations, life-threatening respiratory depression. If efficacy in treating post-surgical pain can be demonstrated, we believe that there will be substantial potential for this product, as there are approximately 20 million surgical procedures performed annually in the United States for which the product could potentially be utilized.

During 2004, our Phase II clinical trial was conducted in surgeries for inguinal hernia repair, which is considered a moderately to severely painful procedure. The results indicated excellent safety and tolerability. The pharmacokinetics of APF112 showed sustained release of mepivacaine systemically over a period of three days (72 hours). No significant difference was shown between the two doses of APF112 and the standard of care (bupivacaine) in terms of pain scores and the amount of additional

9  •  A. P. PHARMA  •  2007 ANNUAL REPORT

pain medication used. Mean Visual Analog Scale, pain scores, or VAS scores, in the standard of care group (bupivacaine) were significantly lower in this study when compared with other previously published studies in similar hernia trials. Based on published data, VAS scores for the standard of care in similar inguinal hernia studies ranged from 4.5 to 6.7, whereas in this study the mean score for the bupivacaine arm was 2.9 within the first 24 hours post surgery. We believe that we can demonstrate that APF112 is effective in controlling post surgical pain, however, we were unable to demonstrate this due to the unexpectedly low levels of pain displayed by the control group in this trial. We intend to complete additional preclinical work in 2008 with a revised protocol, followed by initiation of a Phase IIb clinical trial in the second quarter of 2008. Assuming successful completion of our Phase IIb clinical trial, we plan to explore corporate partnering opportunities to continue the development of APF112.

APF580

APF580 will incorporate an opiate into our Biochronomer technology and is designed to provide analgesia lasting at least seven days by a single injection. It is targeted for situations where the intensity and duration of pain require use of an opiate rather than a local anesthetic. APF580 may find use in acute and chronic pain settings, improve patient compliance and reduce the risk of drug abuse. Our initial animal pharmacokinetic studies completed in 2006 present a promising profile, supporting future product development for post-surgical (inpatient) and chronic pain applications (cancer pain). We plan to supplement our animal studies with additional preclinical data from an ongoing research and development agreement with a major animal health company, which is evaluating the same product for use in cats and dogs. We plan to initiate a Phase I clinical trial of APF580 in the second quarter of 2008.

APF328

APF328 represents a novel formulation in preclinical development for the potential treatment of pain following orthopedic surgery. Our Biochronomer polymer has been designed in this instance to control the local delivery of meloxicam for up to two weeks. Meloxicam is a non-steroidal anti-inflammatory drug that was developed as an oral tablet for the treatment of osteoarthritis of the knee and hip.

APF505

APF505 is an extension of the concept outlined in APF328. This Biochronomer formulation has the potential to deliver meloxicam within the knee joint for up to six weeks and may be appropriate to treat the inflammation and pain associated with osteoarthritis, a common form of arthritis that occurs in nearly 70% of the U.S. population over the age of 65. For both APF328 and APF505, our objective is to deliver the drug to the site of action, thereby avoiding the side effects associated with oral treatment, namely gastrointestinal disturbances.

Our Technology Platform

We have made significant investments in the development of our bioerodible drug delivery technologies, which have created tangible results. Specifically, we have developed a broad family of polymers with unique attributes, known collectively as poly(ortho esters), under the trade name Biochronomer. This technology has been specifically designed for use in drug delivery

A. P. PHARMA  •  2007 ANNUAL REPORT  •  10

applications with a number of technical advantages, such as: ease of manufacturing, flexible delivery times, various physical forms and multiple potential applications due to a neutral pH environment for acid sensitive actives (nucleic acids, proteins, etc.).

Due to the inherent versatility of our Biochronomer technology, products can be designed to deliver drugs at a variety of implantation sites including, under the skin, at the site of a surgical procedure, in joints, in the eye, or in muscle tissue. Our Biochronomer technology can provide sustained levels of drugs in systemic circulation for prolonged efficacy.

Ease of Manufacturing. Our Biochronomer technology is formed by the coupling of various monomers into a polymer chain. Our process knowledge underlying the commercial manufacture of our Biochronomers is based on extensive, well-documented, development studies. Commercial manufacturing campaigns to date have demonstrated that our Biochronomers may be produced in a highly reproducible manner. By selecting suitable monomers the resulting polymers will melt at differing temperatures which will allow for different manufacturing techniques, e.g. injection molding, extrusion, compression molding, etc.

Flexible Delivery Times. The Biochronomer “links” or bonds are stable at neutral pH conditions. Upon coming into contact with water-containing media, such as internal body fluids, the water reacts with these bonds. This reaction is known as hydrolysis. During the hydrolysis of the Biochronomer links, acidic elements are produced in a local micro-environment, in a controlled manner, without impacting the overall neutrality of the drug delivery technology. These elements assist in the continued, controlled erosion of the polymer with a simultaneous, controlled release of the active drug contained within the Biochronomer. By varying the amount of the acidic elements in the Biochronomer, different rates of hydrolysis may be effectively realized. In this manner, delivery times ranging from days to weeks to several months can be achieved.

Various Physical Forms. Our Biochronomers can be prepared in a variety of physical forms, ranging from hard, glassy materials to semi-solids that are injectable at room temperature, by proper selection of monomers. A significant advantage of our Biochronomer technology is that drugs can be incorporated by simple mixing procedures allowing the production of formulations in the form of injectable gels, microspheres, coatings, and strands. All of these physical forms can be used in the controlled delivery of drugs without the undesirable incorporation of organic solvents in the final product.

Multiple Potential Applications. We have completed over 100 in vivo and in vitro studies demonstrating that our Biochronomer technology is potentially applicable to a range of therapeutic areas, including pain management, prevention of nausea, control of inflammation and treatment of ophthalmic diseases. We have also completed comprehensive animal and human toxicology studies that have established that our Biochronomer polymers are safe and well tolerated.

All of our current development programs utilize the same semi-solid poly(ortho ester) delivery vehicle. Additional applications for the treatment of a number of indications are under development using the same vehicle. The present forms of these products are stored under refrigeration. We are actively developing products that can be stored at room temperature.

Through our experience and continued insight obtained during our research and development, Biochronomer polymers can be extended into novel technologies via the design of additional architectures containing poly(ortho esters). One example of such a technology is our family of polymers called Bioerodimers. These polymers are poly(ethylene glycol) products that have the ability to

11  •  A. P. PHARMA  •  2006 ANNUAL REPORT

form micelles in water and can be delivered intravenously. We believe this family of polymers may be safer and better tolerated than more conventional intravenous formulations which employ solvents and surfactants. At least eight patents and patent applications cover this and other aspects of our Bioerodimer technologies. The materials resulting from these inventions have the potential to be exploited in the creation of new drug delivery technologies that can be used to treat more indications via additional delivery routes.

Our Strategy

Our primary objective is to be a leading specialty pharmaceutical company focused on improving the effectiveness of existing pharmaceuticals using our proprietary drug delivery technologies. Key elements include:

Expand product pipeline. We plan to expand our product pipeline by leveraging our existing technology. We intend to develop new products based on our Biochronomer polymer-based drug delivery technology. Our research has indicated that our Biochronomer technology has potential applications across a range of therapeutic areas including prevention of nausea, pain management, control of inflammation and treatment of ophthalmic diseases. With further work on our technology platforms, we may be able to develop products that deliver proteins, peptides, sRNA (soluble RNA) and RNAi (RNA interference).

Minimize product development risk and time-to-market. We are applying our proprietary drug delivery technologies to improve the effectiveness of approved pharmaceutical products. By using our technologies to administer drugs for which clinical efficacy and safety data are available, we will reduce the cost and development risk inherent in traditional pharmaceutical product development.

Maximize the value of our lead product, APF530. We believe that establishing a partnership with an established pharmaceutical company for the commercialization of APF530 will maximize the value of APF530 for our shareholders. We expect to secure significant upfront license fees, followed by milestone payments and royalties. We also plan to evaluate separate commercial partnerships for the United States and the rest of world.

Enter into strategic partnerships. We believe that selective partnering of our future product development programs can enhance the success of our product development and commercialization efforts, and enable diversification of our product portfolio by having partners fund the major portion of our late stage clinical trials. Additionally, such partnering will enable us to leverage the sales capabilities of our partners to commercialize our products.

Manufacturing and Supply

We do not currently own or operate manufacturing facilities for the production of clinical or commercial quantities of any of our product candidates. We currently rely on a small number of third-party manufacturers to produce our compounds and expect to continue to do so to meet the preclinical and clinical requirements of our potential products and for all of our commercial needs. We do not have long-term agreements with any of these third-parties.

A. P. PHARMA  •  2007 ANNUAL REPORT  •  12

We require in our manufacturing and processing agreements that all third-party contract manufacturers and processors produce active pharmaceutical ingredients, or APIs, and finished products in accordance with current good manufacturing practice, or cGMP, and all other applicable laws and regulations. We maintain confidentiality agreements with potential and existing manufacturers in order to protect our proprietary rights related to our drug candidates.

With regard to our lead product candidate, APF530, we currently use Sigma Aldrich Corporation as our primary raw materials and polymer supplier. We currently source granisetron from one supplier and know of at least three other capable suppliers. We currently ship all of our formulation components directly to our contract manufacturer, Hyaluron, Inc. We continue to evaluate potential suppliers and manufacturers.

Marketing and Sales

A key part of our business strategy is to form collaborations with pharmaceutical partners. In the past, we have successfully partnered our development stage programs with leading pharmaceutical companies. In general, we grant limited marketing exclusivity in defined markets for defined periods to our partners. However, after development is completed and a partner commercializes a formulated product utilizing our delivery technologies, we can exert only limited influence over the manner and extent of our partner’s marketing efforts.

The status of our initial marketing relationships for APF530 are as follows:

•  In October 2006, we announced that we had granted an exclusive license to RHEI Pharmaceuticals, Inc. to seek regulatory approval and sell APF530 in China, Taiwan, Hong Kong and Macau. The agreement included an upfront payment to us and includes provisions for milestone payments and royalties on future net sales.

•  During the Phase III trial and the period preceding filing an NDA we will continue to seek additional domestic and international partners.

Patents and Trade Secrets

As part of our strategy to protect our current products and to provide a foundation for future products, we have filed a number of United States patent applications on inventions relating to the composition of a variety of polymers, specific products, product groups and processing technology. In addition to obtaining patents in a number of foreign countries, we have also filed the United States and foreign patent applications on our polymer technology with the Patent Cooperation Treaty (PCT), the European Patent Office, Australia, Canada, China, Hong Kong, Japan, South Korea, Singapore and Taiwan. We have a total of 21 issued United States patents and an additional 64 issued (or registered) foreign patents. The patents on the bioerodible technologies expire between January 2016 and November 2022.

13  •  A. P. PHARMA  •  2006 ANNUAL REPORT

Although we believe the bases for these patents and patent applications are sound, they are untested, and there is no assurance that they will not be successfully challenged. There can be no assurance that any patent previously issued will be of commercial value, that any patent applications will result in issued patents of commercial value, or that our technology will not be held to infringe patents held by others.

We also rely on unpatented trade secrets and know-how to protect certain aspects of our production technologies. Our employees, consultants, advisors and corporate partners have entered into confidentiality agreements with us. These agreements, however, may not necessarily provide meaningful protection for our trade secrets or proprietary know-how in the event of unauthorized use or disclosure. In addition, others may obtain access to, or independently develop, these trade secrets or know-how.

Competition

There are several companies that are developing new formulations of existing drugs using novel drug delivery technologies. Many of these companies have substantially greater financial, research and development, manufacturing, sales and marketing and distribution resources and experience than we do. The following are our major competitors:

•  Alkermes, Inc.

•  Depomed, Inc.

•  Durect Corporation

•  ProStrakan Group PLC

•  SkyePharma PLC

Additionally, APF530 is expected to face competition from Eisai/MGI Pharma’s Aloxi (palonosetron), Roche’s Kytril (granisetron), GlaxoSmithKline’s Zofran (ondansetron), and Aventis’ Anzemet (dolasetron), as well as Hana Biosciences’ Zensana (oral ondansetron), including generic versions of certain of these products. We are also aware of several companies which have developed or are developing both generic and new formulations of granisetron, including transdermal formulations. APF112 is expected to face competition from Durect Corporation’s Posidur (injectable controlled release bupivacaine) and SkyePharma PLC’s recently divested DepoBupivacaine (injectable controlled release bupivacaine).

Government Regulation and Product Approvals

The manufacturing and marketing of our potential products and our ongoing research and development activities are subject to extensive regulation by the FDA and comparable regulatory agencies in state and local jurisdictions and in foreign countries.

A. P. PHARMA  •  2007 ANNUAL REPORT  •  14

United States Regulation

Before any of our products can be marketed in the United States, they must secure approval by the FDA. To secure approval, any drug we develop must undergo rigorous preclinical testing and clinical trials that demonstrate the product candidate’s safety and effectiveness for each chosen indication for use. This extensive regulatory process controls, among other things, the development, testing, manufacture, safety, efficacy, record keeping, labeling, storage, approval, advertising, promotion, sale, and distribution of biopharmaceutical products.

In general, the process required by the FDA before investigational drugs may be marketed in the United States involves the following steps:

•  preclinical laboratory and animal tests;

•  submission of an investigational new drug application, or IND, which must become effective before human clinical trials may begin;

•  adequate and well-controlled human clinical trials to establish the safety and efficacy of the proposed drug for its intended use;

•  pre-approval inspection of manufacturing facilities and selected clinical investigators; and

•  FDA approval of a new drug application, or NDA, or of a NDA supplement (for subsequent indications).

Preclinical Testing

In the United States, drug candidates are tested in animals until adequate proof of safety is established. These preclinical studies generally evaluate the mechanism of action of the product and assess the potential safety and efficacy of the product. Tested compounds must be produced according to applicable current good manufacturing practice (cGMP) requirements and preclinical safety tests must be conducted in compliance with FDA and international regulations regarding good laboratory practices (GLP). The results of the preclinical tests, together with manufacturing information and analytical data, are generally submitted to the FDA as part of an investigational new drug application, or IND, which must become effective before human clinical trials may commence. The IND will automatically become effective 30 days after receipt by the FDA, unless before that time the FDA requests an extension or raises concerns about the conduct of the clinical trials as outlined in the application. If the FDA has any concerns, the sponsor of the application and the FDA must resolve the concerns before clinical trials can begin. Submission of an IND may not result in FDA authorization to commence a clinical trial. A separate submission to the existing IND must be made for each successive clinical trial conducted during product development, and the FDA must grant permission for each clinical trial to start and continue. Regulatory authorities may require additional data before allowing the clinical studies to commence or proceed from one Phase to another, and could demand that the studies be discontinued or suspended at any time if there are significant safety issues. Furthermore, an independent institutional review board, or IRB, for each medical center proposing to participate in the conduct of the clinical trial must review and approve the clinical protocol and patient informed consent before the center commences the study.

15  •  A. P. PHARMA  •  2006 ANNUAL REPORT

Clinical Trials

Clinical trials for new drug candidates are typically conducted in three sequential phases that may overlap. In Phase I, the initial introduction of the drug candidate into human volunteers, the emphasis is on testing for safety or adverse effects, dosage, tolerance, metabolism, distribution, excretion, and clinical pharmacology. Phase II involves studies in a limited patient population to determine the initial efficacy of the drug candidate for specific targeted indications, to determine dosage tolerance and optimal dosage and to identify possible adverse side effects and safety risks. Once a compound shows evidence of effectiveness and is found to have an acceptable safety profile in Phase II evaluations, pivotal Phase III trials are undertaken to more fully evaluate clinical outcomes and to establish the overall risk/benefit profile of the drug, and to provide, if appropriate, an adequate basis for product labeling. During all clinical trials, physicians will monitor patients to determine effectiveness of the drug candidate and to observe and report any reactions or safety risks that may result from use of the drug candidate. The FDA, the IRB (or their foreign equivalents) or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects are being exposed to an unacceptable health risk.

The data from the clinical trials, together with preclinical data and other supporting information that establishes a drug candidate’s safety, are submitted to the FDA in the form of a new drug application, or NDA, or NDA supplement (for approval of a new indication if the product candidate is already approved for another indication). Under applicable laws and FDA regulations, each NDA submitted for FDA approval is usually given an internal administrative review within 45 to 60 days following submission of the NDA. If deemed complete, the FDA will “file” the NDA, thereby triggering substantive review of the application.

The FDA can refuse to file any NDA that it deems incomplete or not properly reviewable. The FDA has established internal substantive review goals of six months for priority NDAs (for drugs addressing serious or life threatening conditions for which there is an unmet medical need) and ten months for regular NDAs. The FDA, however, is not legally required to complete its review within these periods, and these performance goals may change over time. Moreover, the outcome of the review, even if generally favorable, is not typically an actual approval, but an “action letter” that describes additional work that must be done before the NDA can be approved. The FDA’s review of a NDA may involve review and recommendations by an independent FDA advisory committee. The FDA may deny approval of a NDA or NDA supplement if the applicable regulatory criteria are not satisfied, or it may require additional clinical data and/or an additional pivotal Phase III clinical trial. Even if such data are submitted, the FDA may ultimately decide that the NDA or NDA supplement does not satisfy the criteria for approval.

Data Review and Approval

Satisfaction of FDA requirements or similar requirements of state, local, and foreign regulatory agencies typically takes several years and requires the expenditure of substantial financial resources. Information generated in this process is susceptible to varying interpretations that could delay, limit, or prevent regulatory approval at any stage of the process. Accordingly, the actual time and expense required to bring a product to market may vary substantially. We cannot assure you that we will submit applications for required authorizations to manufacture and/or market potential products or that any such application will be reviewed and approved by the appropriate regulatory authorities in a timely manner, if at all. Data obtained from clinical activities is not always conclusive and may be susceptible to varying interpretations, which could delay, limit, or prevent regulatory approval. Success in early stage clinical trials does not ensure success in later stage clinical trials. Even if a product candidate receives regulatory approval, the approval may be significantly limited to specific disease states, patient populations, and dosages, or have conditions placed on them that restrict the commercial applications, advertising, promotion, or distribution of these products.

A. P. PHARMA  •  2007 ANNUAL REPORT  •  16

Once issued, the FDA may withdraw product approval if ongoing regulatory standards are not met or if safety problems occur after the product reaches the market. In addition, the FDA may require testing and surveillance programs to monitor the effect of approved products which have been commercialized, and the FDA has the power to prevent or limit further marketing of a product based on the results of these post-marketing programs. The FDA may also request additional clinical trials after a product is approved. These so-called Phase 4 studies may be made a condition to be satisfied after a drug receives approval. The results of Phase IV studies can confirm the effectiveness of a product candidate and can provide important safety information to augment the FDA’s voluntary adverse drug reaction reporting system. Any products manufactured or distributed by us pursuant to FDA approvals would be subject to continuing regulation by the FDA, including record-keeping requirements and reporting of adverse experiences with the drug. Drug manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with good manufacturing practices, which impose certain procedural and documentation requirements upon us and our third-party manufacturers. We cannot be certain that we or our present or future suppliers will be able to comply with the good manufacturing practices regulations and other FDA regulatory requirements. If our present or future suppliers are not able to comply with these requirements, the FDA may halt our clinical trials, require us to recall a drug from distribution, or withdraw approval of the NDA for that drug. Furthermore, even after regulatory approval is obtained, later discovery of previously unknown problems with a product may result in restrictions on the product or even complete withdrawal of the product from the market.

The FDA closely regulates the marketing and promotion of drugs. Approval may be subject to post-marketing surveillance and other record keeping and reporting obligations, and involve ongoing requirements. Product approvals may be withdrawn if compliance with regulatory standards is not maintained or if problems occur following initial marketing. A company can make only those claims relating to safety and efficacy that are approved by the FDA. Failure to comply with these requirements can result in adverse publicity, warning letters, corrective advertising, and potential civil and criminal penalties. Physicians may prescribe legally available drugs for uses that are not described in the product’s labeling and that differ from those tested by us and approved by the FDA. Such off-label uses are common across medical specialties. Physicians may believe that such off-label uses are the best treatment for many patients in varied circumstances. The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA does, however, restrict manufacturers’ communications on the subject of off-label use.

Section 505(b)(2) Applications

Some of our product candidates may be eligible for submission of applications for approval under the FDA’s Section 505(b)(2) approval process, which requires less information than the NDAs described above. Section 505(b)(2) applications may be submitted for drug products that represent a modification (e.g., a new indication or new dosage form) of an eligible approved drug and for which investigations other than bioavailability or bioequivalence studies are essential to the drug’s approval. Section 505(b)(2) applications may rely on the FDA’s previous findings for the safety and effectiveness of the listed drug, scientific literature, and information obtained by the 505(b)(2) applicant needed to support the modification of the listed drug. For this reason, preparing Section 505(b)(2) applications is generally less costly and time-consuming than preparing an NDA based entirely on new data and information from a full set of clinical trials. The law governing Section 505(b)(2) or FDA’s current policies may change in such a way as to adversely affect our applications for approval that seek to utilize the Section 505(b)(2) approach. Such changes could result in additional costs associated with additional studies or clinical trials and delays.

17  •  A. P. PHARMA  •  2007 ANNUAL REPORT

The FDA provides that reviews and/or approvals of applications submitted under Section 505(b)(2) will be delayed in various circumstances. For example, the holder of the NDA for the listed drug may be entitled to a period of market exclusivity, during which the FDA will not approve, and may not even review a Section 505(b)(2) application from other sponsors. If the listed drug is claimed by patent that the NDA holder has listed with the FDA, the Section 505(b)(2) applicant must submit a patent certification. If the 505(b)(2) applicant certifies that the patent is invalid, unenforceable, or not infringed by the product that is the subject of the Section 505(b)(2), and the 505(b)(2) applicant is sued within 45 days of its notice to the entity that holds the approval for the listed drug and the patent holder, the FDA will not approve the Section 505(b)(2) application until the earlier of a court decision favorable to the Section 505(b)(2) applicant or the expiration of 30 months. The regulations governing marketing exclusivity and patent protection are complex, and it is often unclear how they will be applied in particular circumstances.

In addition, both before and after approval is sought, we and our collaborators are required to comply with a number of FDA requirements. For example, we are required to report certain adverse reactions and production problems, if any, to the FDA, and to comply with certain limitations and other requirements concerning advertising and promotion for our products. Also, quality control and manufacturing procedures must continue to conform to continuing GMP after approval, and the FDA periodically inspects manufacturing facilities to assess compliance with continuing GMP. In addition, discovery of problems such as safety problems may result in changes in labeling or restrictions on a product manufacturer or NDA holder, including removal of the product from the market.

Foreign Approvals

In addition to regulations in the United States, we will be subject to a variety of foreign regulations governing clinical trials and commercial sales and distribution of our products. Whether or not we obtain FDA approval for a product, we must obtain approval of a product by the comparable regulatory authorities of foreign countries before we can commence clinical trials or marketing of the product in those countries. The approval process varies from country to country, and the time may be longer or shorter than that required for FDA approval. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from country to country.

Under European Union regulatory systems, we may submit marketing authorizations either under a centralized or decentralized procedure. The centralized procedure provides for the grant of a single marketing authorization that is valid for all European Union member states. The decentralized procedure provides for mutual recognition of national approval decisions. Under this procedure, the holder of a national marketing authorization may submit an application to the remaining member states. Within 90 days of receiving the applications and assessment report, each member state must decide whether to recognize approval.

The policies of the FDA and foreign regulatory authorities may change and additional government regulations may be enacted which could prevent or delay regulatory approval of our investigational drugs or approval of new diseases for our existing products. We cannot predict the likelihood, nature or extent of adverse governmental regulation that might arise from future legislative or administrative action, either in the United States or abroad.

ITEM 1A. RISK FACTORS

Our business is subject to various risks, including those described below. You should consider carefully these risk factors and all of the other information included in this Form 10-K. Any of these risk factors could materially adversely affect our business, operating results and financial condition.

Risks Related To Our Business

We have a history of losses, we expect to generate losses in the near future, and we may never achieve or maintain profitability.

We have incurred recurring losses and had an accumulated deficit of $107.9 million as of December 31, 2007. We expect to continue to generate substantial losses over at least the next several years as we:

•  expand drug product development efforts;

•  conduct preclinical testing and clinical trials; and

•  pursue additional applications for our existing delivery technologies.

To achieve and sustain profitability, we must, alone or with others, successfully develop, obtain regulatory approval for, manufacture, market and sell our products. We will incur substantial expenses in our efforts to develop and commercialize products and we may never generate sufficient revenue to become profitable or to sustain profitability.

Additional capital will be needed to enable us to implement our business plan. Raising such capital may have to be accomplished on unfavorable terms, possibly causing dilution to our existing stockholders

We will require additional capital resources in order to conduct our operations and develop our products. We may not be able to obtain required funding on favorable terms and required funding may cause dilution to our existing stockholders. The timing and degree of any future capital requirements will depend on many factors, including:

•  the number of product development programs we pursue and the pace of each program;

•  the scope, rate of progress, results and costs of preclinical testing and clinical trials;

•  the time and costs involved in seeking regulatory approvals;

•  scientific progress in our research and development programs;

•  the magnitude and scope of our research and development programs;

A. P. PHARMA  •  2007 ANNUAL REPORT  •  20

•  our ability to establish and maintain strategic collaborations or partnerships for research, development, clinical testing, manufacturing and marketing; and

•  market conditions and other factors.

We intend to acquire additional funding through strategic collaborations, in the form of license fees, research and development fees and milestone payments, and/or possibly through sales of our common stock or other company securities. In the event that additional funds are obtained through arrangements with collaborative partners, these arrangements may require us to relinquish rights to some of our technologies, product candidates or products that we would otherwise seek to develop and commercialize ourselves. If we issue additional equity securities or securities convertible into equity securities to raise funds, our stockholders will suffer dilution of their investment and it may adversely affect the market price of our common stock. If adequate funds are not available, we will be required to delay, reduce the scope of, or eliminate one or more of our product development programs and reduce personnel-related and other costs, which will have a material adverse effect on our business.

We are substantially dependent upon the success of our APF530 product candidate. Clinical trials for this product may not demonstrate efficacy or lead to regulatory approval.

We will not be able to commercialize our lead product candidate, APF530, until we obtain regulatory approval in the United States or foreign countries. To satisfy FDA or foreign regulatory approval standards for the commercial sale of our product candidates, we must demonstrate in adequate and controlled clinical trials that our product candidates are safe and effective. Success in preclinical testing and early clinical trials does not ensure that later clinical trials will be successful. A number of companies in the pharmaceutical industry, including us, have suffered significant setbacks in advanced clinical trials, even after obtaining promising results in earlier clinical trials.

Our lead product candidate, APF530, is designed to provide at least five days prevention of CINV. In September 2005, we completed a Phase II human clinical trial of APF530 that achieved all of its primary and secondary endpoints. In May 2006, we initiated our pivotal Phase III clinical trial of AFP530.

Although we believe that this clinical trial will lead to regulatory approval of APF530 for the prevention of acute and delayed onset CINV for patients undergoing both moderately and highly emetogenic, or vomit-inducing, chemotherapy, the results of initial preclinical testing and clinical trials to date do not necessarily predict the results that we will get from subsequent or more extensive preclinical testing and clinical trials. Clinical trials of APF530 and our other product candidates may not demonstrate that they are safe and effective to the extent necessary to obtain regulatory approvals. If we cannot adequately demonstrate through the clinical trial process that the product we are developing is safe and effective, regulatory approval of that product would be delayed or prevented, which would impair our reputation, increase our costs and prevent us from earning revenue.

We may not obtain regulatory approval for our products. Regulatory approval may also be delayed or cancelled or may entail limitations on the indicated uses of a proposed product.

The regulatory process, particularly for biopharmaceutical products like ours, is uncertain, can take many years and requires the expenditure of substantial resources. Any product that we or our collaborative partners develop must receive all relevant

21  •  A. P. PHARMA  •  2007 ANNUAL REPORT

regulatory agency approvals or clearances, if any, before it may be marketed in the United States or other countries. In particular, human pharmaceutical therapeutic products are subject to rigorous preclinical and clinical testing and other requirements by the Food and Drug Administration, or FDA, in the United States and similar health authorities in foreign countries. We may not receive necessary regulatory approvals or clearances to market APF530 or any other product candidate.

Data obtained from preclinical and clinical activities is susceptible to varying interpretations that could delay, limit or prevent regulatory agency approvals or clearances. For example, the FDA may require additional clinical data to support approval, such as confirmatory studies, carcinogenicity studies and other data or studies to address questions or concerns that may arise during the FDA review process. Delays or rejections also may be encountered as a result of changes in regulatory agency policy during the period of product development and/or the period of review of any application for regulatory agency approval or clearance for a product. Delays in obtaining regulatory agency approvals or clearances could:

•  significantly harm the marketing of any products that we or our collaborators develop;

•  impose costly procedures upon our activities or the activities of our collaborators;

•  diminish any competitive advantages that we or our collaborative partners may attain; or

•  adversely affect our ability to receive royalties and generate revenue and profits.

Even though we intend to apply for approval of most of our products in the United States under Section 505(b)(2) of the United States Food, Drug and Cosmetic Act, or FDCA, which applies to reformulations of approved drugs and that may require smaller and shorter safety and efficacy testing than that for entirely new drugs, the approval process will still be costly, time-consuming and uncertain. We plan to file the NDA for APF530 under Section 505(b)(2) of the FDCA, to rely on previous FDA findings of safety and efficacy of the active ingredient in APF530, granisetron. While we believe that Section 505(b)(2) is applicable to APF530, it is possible that the FDA may disagree and require us to submit a “stand-alone” or “full” Section 505(b)(1) NDA, which would require significantly more clinical studies and or other data collection or analysis.

We or our collaborators may not be able to obtain necessary regulatory approvals on a timely basis, if at all, for any of our potential products. Even if granted, regulatory approvals may include significant limitations on the uses for which products may be marketed. Failure to comply with applicable regulatory requirements can, among other things, result in warning letters, imposition of civil penalties or other monetary payments, delay in approving or refusal to approve a product candidate, suspension or withdrawal of regulatory approval, product recall or seizure, operating restrictions, interruption of clinical trials or manufacturing, injunctions and criminal prosecution.

In addition, the marketing and manufacturing of drugs and biological products are subject to continuing FDA review, and later discovery of previously unknown problems with a product, its manufacture or its marketing may result in the FDA requiring further clinical research or restrictions on the product or the manufacturer, including withdrawal of the product from the market.

A. P. PHARMA  •  2007 ANNUAL REPORT  •  22

Clinical trials are expensive and may not result in commercially viable products.

Conducting clinical trials is a lengthy, time-consuming and expensive process. For example, we are incurring significant expenses in developing APF530, and even if approved, it may not result in a commercially viable product. Before obtaining regulatory approvals for the commercial sale of any products, we or our partners must demonstrate through preclinical testing and clinical trials that our product candidates are safe and effective for use in humans. We have incurred, and we will continue to incur, substantial expense for, and devote a significant amount of time to, preclinical testing and clinical trials.

Our business, results of operations and financial condition may be materially adversely affected by any delays in, or termination of, our clinical trials. Factors impacting our ability to generate commercially viable products through the conduct of clinical trials include:

•  insufficient funds to continue necessary clinical trials;

•  inability to find partners;

•  failure of clinical trials to demonstrate the safety and efficacy of our products to the extent necessary to obtain regulatory approvals;

•  failure of preclinical testing and early clinical trials to predict results of later clinical trials;

•  delay in completion of clinical trials, resulting in increased costs; and

•  inability to obtain regulatory approval of our products following completion of clinical trials, or delays in obtaining such approvals.

Delays in clinical testing could increase our costs and delay our ability to obtain regulatory approval and commercialize our product candidates.

Before we or our collaborators can file for regulatory approval for the commercial sale of our potential products, the FDA will require extensive preclinical safety testing and clinical trials to demonstrate their safety and efficacy. Significant delays in preclinical and clinical testing could materially impact our product development costs and delay regulatory approval of our product candidates. For example, enrollment in the Phase III trial for APF530 has been slower than we expected, resulting in delays in our development timeline and increased costs. Completing clinical trials in a timely manner depends on, among other factors:

•  obtaining regulatory approval to commence a trial;

•  obtaining clinical materials;

•  reaching agreement on acceptable clinical study terms with prospective sites and clinical research organizations;

23  •  A. P. PHARMA  •  2007 ANNUAL REPORT

•  obtaining institutional review board approval to conduct a study at a prospective site; and

•  recruiting patients to participate in a study.

We rely on third parties to conduct our clinical trials, and their failure to perform their obligations in a timely and competent manner may delay development and commercialization of our product candidates.

We are using clinical research organizations in the U.S., India and Poland to oversee our ongoing clinical trial of APF530 and we expect to use the same or similar organizations for our future clinical trials. There are numerous alternative sources to provide these services; however, we may face delays outside of our control if these parties do not perform their obligations in a timely or competent fashion, or if we are forced to change service providers. Different cultural and operational issues in India or Poland could cause delays or unexpected problems with the patient enrollments or with the data obtained from those locations. If we experience significant delays in the progress of our clinical trials and in our plans to file NDAs or problems with the quality of data derived from various clinical sites, the prospects for approval of APF530 in general and on a timely basis could decrease.

We have yet to demonstrate the full commercial viability of our technology, and we cannot be certain that attainment of such a goal can be accomplished.

Our bioerodible drug delivery technology is at an early stage of development. We may not be able to substantiate the capability of our drug delivery technology for a variety of reasons:

•  selection of inappropriate therapeutic compound for delivery;

•  selection of inappropriate application for the particular product candidate;

•  failure to receive regulatory approval on a timely basis or at all; or

•  difficulties with manufacturing in commercial quantities at an acceptable cost.

Successful development of delivery technologies will require significant preclinical and clinical testing prior to regulatory approval, if any. Because of these scientific, regulatory and commercial hurdles, any program could be abandoned or otherwise fail, even after significant resources have been expended.

Recent changes in management may be disruptive.

We had significant changes in management in the past two years. On October 9, 2006, Michael O’Connell, our President and Chief Executive Officer (CEO) began a temporary leave of absence for medical reasons. Effective that same date, Gregory Turnbull, formerly an independent director of the Company, began to serve as President and Chief Executive Officer. Effective September 27, 2006, Stephen Whiteford was appointed the Company’s Vice President, Finance and Chief Financial Officer to replace our former Chief Financial Officer who left the Company on September 12, 2006 to pursue another opportunity. In May 2007, Mr. Whiteford left the Company when Mr. O’Connell returned to active employment as our Chief Operating Officer and

A. P. PHARMA  •  2007 ANNUAL REPORT  •  24

Chief Financial Officer. In December 2007, we announced a CEO succession plan, wherein we were initiating recruitment via an executive recruitment firm of a permanent CEO to take over that position from Mr. Turnbull, who will continue in that role until such a successor is successfully engaged. Then in January 2008, Mr. O’Connell resigned, and Mr. Turnbull assumed the added responsibilities of Chief Financial Officer in addition to his roles as President and Chief Executive Officer. In March 2008, our Controller left her position for another opportunity and we engaged the services of an experienced financial consultant. Additions of new personnel and departures of existing personnel, particularly in key positions, can be disruptive, might lead to additional departures of existing personnel and could have a material adverse effect on our business, operating results, financial condition and internal controls over financial reporting.

If any products that we or our collaborators may develop do not attain adequate market acceptance by healthcare professionals and patients, our business prospects and results of operations will suffer.

Even if a product candidate receives regulatory approval for commercial sale, the revenue received or to be received from the sale of the product may not be significant and will depend on many factors that are outside of our control. Factors that may affect revenue from our product candidates, if and when approved, include:

•  perception of physicians and other members of the health care community of their safety and efficacy relative to that of competing products;

•  cost-effectiveness;

•  patient and physician satisfaction with these products;

•  ability to manufacture commercial products successfully and on a timely basis;

•  cost and availability of raw materials;

•  market size for these products;

•  reimbursement policies of government and third-party payors;

•  unfavorable publicity concerning these products or similar drugs;

•  the introduction, availability and acceptance of competing treatments, including those of our collaborators;

•  adverse event information relating to these products;

•  product labeling or product insert required by the FDA or regulatory authorities in other countries;

•  regulatory developments related to the manufacture or continued use of these products;

25  •  A. P. PHARMA  •  2006 ANNUAL REPORT

•  extent and effectiveness of sales and marketing and distribution support for the products; and

•  our collaborators’ decisions as to the timing of product launches, pricing and discounting.

Our product revenue will be adversely affected if, due to these or other factors, the products we or our collaborators are able to commercialize do not gain significant market acceptance.

We depend on contract manufacturers and collaborators for manufacturing our products; if they do not perform as expected, our revenue and customer relations will suffer.

We do not own or operate manufacturing facilities for the production of clinical or commercial quantities of any product. We rely on a small number of third-party manufacturers to produce our compounds and expect to continue to do so to meet the preclinical and clinical requirements of our potential products and for all of our commercial needs. We have no long-term agreements with any of these third parties. We may not be able to extend these agreements at satisfactory terms, or at all, and we may not be able to find a replacement contract manufacturer at satisfactory terms or on a timely basis.

Further, our contract manufacturers and our collaborators are required to comply with FDA requirements related to product testing, quality assurance, manufacturing and records and documentation. Our contract manufacturers or our collaborators may not be able to comply with the applicable FDA regulatory requirements, which could result in an enforcement or other action, prevent commercialization of our product candidates and impair our reputation and results of operations.

If we fail to comply with continuing federal, state and foreign regulations, we could lose our approvals to market drugs and our business would be seriously harmed.

Following initial regulatory approval of any drugs we may develop, we will be subject to continuing regulatory review, including review of adverse drug experiences and clinical results that are reported after our drug products become commercially available. This would include results from any post-marketing tests or continued actions required as a condition of approval. The manufacturer and manufacturing facilities we use to make any of our drug candidates will be subject to periodic review and inspection by the FDA. If a previously unknown problem or problems with a product or a manufacturing and laboratory facility used by us is discovered, the FDA or foreign regulatory agency may impose restrictions on that product or on the manufacturing facility, including requiring us to withdraw the product from the market. Any changes to an approved product, including the way it is manufactured or promoted, often require FDA approval before the product, as modified, can be marketed. We and our contract manufacturers will be subject to ongoing FDA requirements for submission of safety and other post-market information. If we and our contract manufacturers fail to comply with applicable regulatory requirements, a regulatory agency may:

•  issue warning letters;

•  impose civil or criminal penalties;

•  suspend or withdraw our regulatory approval;

A. P. PHARMA  •  2007 ANNUAL REPORT  •  26

•  suspend or terminate any of our ongoing clinical trials;

•  refuse to approve pending applications or supplements to approved applications filed by us;

•  impose restrictions on our operations;

•  close the facilities of our contract manufacturers; or

•  seize or detain products or require a product recall.

Additionally, such regulatory review covers a company’s activities in the promotion of its drugs, with significant potential penalties and restrictions for promotion of drugs for an unapproved use. Sales and marketing programs are under scrutiny for compliance with various mandated requirements, such as illegal promotions to healthcare professionals. We are also required to submit information on our open and completed clinical trials to public registries and databases; failure to comply with these requirements could expose us to negative publicity, fines and penalties that could harm our business.

If we are unable to recruit and retain skilled employees, we may not be able to achieve our objectives.

We depend on a small number of key management and technical personnel. Retaining our current employees and recruiting qualified scientific personnel to perform future research and development work will be critical to our success. There is a shortage of skilled personnel in our industry, competition is intense for experienced scientists, and an inability to recruit or retain sufficient skilled personnel could result in delays to product development or approval, loss of sales and diversion of management resources.

We face intense competition from other companies.

We face intense competition from companies that are developing new formulations of existing drugs using novel drug delivery technologies. Many of our competitors have much greater financial, research and development, manufacturing, marketing, sales, distribution and managerial resources and experience than we do. Many of them also have much more experience than we do in preclinical testing and clinical trials of new drugs and in obtaining FDA and foreign regulatory approvals.

The following are our major competitors:

•  Alkermes, Inc.

•  Depomed, Inc.

•  Durect Corporation

27  •  A. P. PHARMA  •  2007 ANNUAL REPORT

•  ProStrakan Group PLC

•  SkyePharma PLC

Additionally, APF530 is expected to face competition from Eisai/MGI Pharma’s Aloxi, Roche’s Kytril, GlaxoSmithKline’s Zofran, and Aventis’ Anzemet, each of which is currently on the market, as well as Hana Biosciences’ Zensana, or generic versions of certain of these products. We are also aware of several companies which have developed or are developing both generic and new formulations of granisetron, including transdermal formulations. APF112 is expected to face competition from Durect’s Posidur and SkyePharma’s recently divested DepoBupivacaine. Most or all of the products we could develop or commercialize will face competition from different therapeutic agents intended for treatment of the same indications or from other products incorporating drug delivery technologies. The competition potentially includes all of the pharmaceutical and drug delivery companies in the world. To the extent that we develop or market products incorporating drugs that are off-patent, or are being developed by multiple companies, we will face competition from other companies developing and marketing similar products.

Major technological changes can happen quickly in the biotechnology and pharmaceutical industries, and the development of technologically improved or different products or drug delivery technologies may make our product candidates or platform technologies obsolete or noncompetitive.

Because we or our collaborators must obtain regulatory approval to market our products in the United States and foreign jurisdictions, we cannot predict whether or when we will be permitted to commercialize our products.

Federal, state and local governments in the United States and governments in other countries have significant regulations in place that govern many of our activities. The preclinical testing and clinical trials of the products that we develop ourselves or that our collaborators develop are subject to government regulation and may prevent us from creating commercially viable products from our discoveries. These regulations and their application may change making it more difficult or prohibitive to develop our products. In addition, the sale by us or our collaborators of any commercially viable product will be subject to government regulation from several standpoints, including the processes of:

•  manufacturing;

•  labeling;

•  distributing;

•  advertising and promoting; and

•  selling and marketing.

A. P. PHARMA  •  2007 ANNUAL REPORT  •  28

We depend on our collaborators to help us complete the process of developing and testing our products.

Our strategy for the development, clinical testing and commercialization of our products requires entering into collaborations with corporate partners, licensors, licensees and others. These collaborations are critical to our success in bringing our products and product candidates to the market and promoting such marketed products profitably. We are dependent upon the subsequent success of these other parties in performing their respective responsibilities and the cooperation of our partners. Our collaborators may not cooperate with us or perform their obligations under our agreements with them. We cannot control the amount and timing of our collaborators’ resources that will be devoted to our research activities related to our collaborative agreements with them. Our collaborators may choose to pursue existing or alternative technologies in preference to those being developed in collaboration with us. Failure to make or maintain these arrangements or a delay in a collaborative partner’s performance or factors that may affect our partner’s sales may materially adversely affect our business, results of operations and financial condition.

Under agreements with collaborators, we may rely significantly on them, among other activities, to:

•  fund research and development activities with us;

•  pay us fees upon the achievement of milestones; and

•  market with us any commercial products that result from our collaborations.

Our business strategy includes the entry into additional collaborative agreements. We may not be able to enter into additional collaborative agreements or may not be able to negotiate commercially acceptable terms for these agreements.

Our current business strategy includes the entry into additional collaborative agreements for the development and commercialization of our delivery technologies. The negotiation and consummation of these types of agreements typically involve simultaneous discussions with multiple potential collaborators and require significant time and resources from our officers, business development, legal and research and development staff. In addition, in attracting the attention of pharmaceutical and biotechnology company collaborators, we compete with numerous other third parties with product opportunities as well the collaborators’ own internal product opportunities. We may not be able to consummate additional collaborative agreements, or we may not be able to negotiate commercially acceptable terms for these agreements. If we do not consummate additional collaborative agreements, we may have to consume money more rapidly on our product development efforts, defer development activities or forego the exploitation of certain geographic territories, any of which could have a material adverse effect on our business.

If we or our collaborators cannot arrange for adequate third-party reimbursement for our products, our future revenue will suffer.

In both domestic and foreign markets, sales of our potential products will depend in substantial part on the availability of adequate reimbursement from third-party payors such as government health administration authorities, private health insurers

29  •  A. P. PHARMA  •  2007 ANNUAL REPORT

and other organizations. Third-party payors often challenge the price and cost-effectiveness of medical products and services and such pressure may increase in the future. Significant uncertainty exists as to the adequate reimbursement status of newly approved health care products. Any products we are able to successfully develop may not be reimbursable by third-party payors. In addition, our products may not be considered cost-effective and adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize a profit. Legislation and regulations affecting the pricing of pharmaceuticals may change before our products are approved for marketing and any such changes could further limit reimbursement. If any products we develop do not receive adequate reimbursement, our revenue will be severely limited.

Our inability to obtain specialized materials could slow down our research and development process.

Some of the critical materials and components used in our products in development are sourced from a single supplier. An interruption in supply of a key material could significantly delay our research and development process or increase our expenses.

Specialized materials must often be manufactured for the first time for use in drug delivery technologies, or materials may be used in the technologies in a manner different from their customary commercial uses. The quality of materials can be critical to the performance of a drug delivery technology, so a reliable source of a consistent supply of materials is important. Materials or components needed for our drug delivery technologies may be difficult to obtain on commercially reasonable terms, particularly when relatively small quantities are required, or if the materials traditionally have not been used in pharmaceutical products.

If we are unable to adequately protect or enforce our intellectual property rights or secure rights to third-party patents, we may lose valuable assets, experience reduced market share or incur costly litigation to protect our rights or our third-party collaborators may choose to terminate their agreements with us.

Our success will depend in part on our ability to obtain patents, maintain trade secret protection and operate without infringing the proprietary rights of others. We have filed a number of U. S. patent applications on inventions relating to the composition of a variety of polymers, specific products, product groups and processing technology. In addition to obtaining patents in a number of foreign countries, we have also filed U.S. and foreign patent applications on our polymer technology with the Patent Cooperation Treaty (PCT), the European Patent Office, Australia, Canada, China, Hong Kong, Japan, South Korea, Singapore and Taiwan. We have a total of 21 issued United States patents and an additional 64 issued (or registered) foreign patents. The patents on the bioerodible technologies expire between January 2016 and November 2022. Our existing patents may not cover future products, additional patents may not be issued, and current patents or patents issued in the future may not provide meaningful protection or prove to be of commercial benefit.

The patent positions of pharmaceutical companies, including ours, are uncertain and involve complex legal and factual questions. In addition, the coverage claimed in a patent application can be significantly reduced before the patent is issued. Consequently, our patent applications or those that are licensed to us may not issue into patents, and any issued patents may not provide protection against competitive technologies or may be held invalid if challenged or circumvented. Our competitors may also independently develop products similar to ours or design around or otherwise circumvent patents issued to us or licensed by us. In addition, the laws of some foreign countries may not protect our proprietary rights to the same extent as the U.S. law.

We are party to collaborative agreements. These agreements subject us to obligations which must be fulfilled and require us to manage complex relationships with third parties. If we are unable to meet our obligations or manage our relationships with our

A. P. PHARMA  •  2007 ANNUAL REPORT  •  30

collaborators under these agreements or enter into additional collaboration agreements or if our existing collaborations are terminated, our revenue may decrease. Our third-party collaborators have entered into these agreements based on the exclusivity that our intellectual property rights confer on the products being developed. The loss or diminution of our intellectual property rights could result in a decision by our third-party collaborators to terminate their agreements with us. In addition, these agreements are generally complex and contain provisions that could give rise to legal disputes, including potential disputes concerning ownership of intellectual property and data under collaborations. Such disputes can lead to lengthy, expensive litigation or arbitration requiring us to devote management time and resources to such dispute which we would otherwise spend on our business.

We also rely upon trade secrets, technical know-how and continuing technological innovation to develop and maintain our competitive position. We require our employees, consultants, advisors and collaborators to execute appropriate confidentiality and assignment-of-inventions agreements with us. These agreements typically provide that all materials and confidential information developed or made known to the individual during the course of the individual’s relationship with us is to be kept confidential and not disclosed to third parties except in specific circumstances, and that all inventions arising out of the individual’s relationship with us shall be our exclusive property. These agreements may be breached, and in some instances, we may not have an appropriate remedy available for breach of the agreements. Furthermore, our competitors may independently develop substantially equivalent proprietary information and techniques, reverse engineer our information and techniques, or otherwise gain access to our proprietary technology. We may be unable to meaningfully protect our rights in trade secrets, technical know-how and other non-patented technology. We may have to resort to litigation to protect our intellectual property rights, or to determine their scope, validity or enforceability. In addition, interference proceedings declared by the United States Patent and Trademark Office may be necessary to determine the priority of inventions with respect to our patent applications. Enforcing or defending our proprietary rights is expensive, could cause diversion of our resources and may not prove successful. Any failure to enforce or protect our rights could cause us to lose the ability to exclude others from using our technology to develop or sell competing products.

We may infringe on the intellectual property rights of others, and any litigation could force us to stop developing or selling potential products and could be costly, divert management attention and harm our business.

We must be able to develop products without infringing the proprietary rights of other parties. Because the markets in which we operate involve established competitors with significant patent portfolios, including patents relating to the composition of a variety of polymers, specific products, product groups and processing technology, it could be difficult for us to use our technologies or develop products without infringing the proprietary rights of others. We may not be able to design around the patented technologies or inventions of others and we may not be able to obtain licenses to use patented technologies on acceptable terms, or at all. If we cannot operate without infringing the proprietary rights of others, we will not earn product revenue.

If we are required to defend ourselves in a lawsuit, we could incur substantial costs and the lawsuit could divert management attention, regardless of the lawsuit’s merit or outcome. These legal actions could seek damages and seek to enjoin testing, manufacturing and marketing of the accused product or process. In addition to potential liability for significant damages, we could be required to obtain a license to continue to manufacture or market the accused product or process and any license required under any such patent may not be made available to us on acceptable terms, if at all.

31  •  A. P. PHARMA  •  2007 ANNUAL REPORT

Periodically, we review publicly available information regarding the development efforts of others in order to determine whether these efforts may violate our proprietary rights. We may determine that litigation is necessary to enforce our proprietary rights against others. Such litigation could result in substantial expense, regardless of its outcome, and may not be resolved in our favor.

Furthermore, patents already issued to us or our pending patent applications may become subject to dispute, and any disputes could be resolved against us. In addition, because patent applications in the United States are currently maintained in secrecy for a period of time prior to issuance, and patent applications in certain other countries generally are not published until more than 18 months after they are first filed, and because publication of discoveries in scientific or patent literature often lags behind actual discoveries, we cannot be certain that we were the first creator of inventions covered by our pending patent applications or that we were the first to file patent applications on such inventions.

We are exposed to risks and increased expenses as a result of laws requiring small business filers to evaluate internal controls over financial reporting.

Section 404 of the Sarbanes-Oxley Act of 2002 requires our management to evaluate the effectiveness of our internal controls over financial reporting as of the end of each fiscal year, and to include a management report assessing the effectiveness of our internal control over financing reporting in our annual report on Form 10-K for each fiscal year. Section 404 also requires our independent auditors to attest to, and report on, our internal control over financial reporting beginning with the year ending December 31, 2008. We have implemented an ongoing program to perform the system and process evaluation and testing we believe to be necessary to comply with these requirements. However, we cannot assure you that we will be successful in our efforts. We expect to incur increased expense and to devote additional management resources to Section 404 compliance. Any failure to implement required new or improved controls, or difficulties encountered in the implementation or operation of these controls, could harm our operating results and cause us to fail to meet our financial reporting obligations, which could adversely affect our business and reduce our stock price.

Legislative actions, potential new accounting pronouncements and higher insurance costs are likely to impact our future financial position or results of operations.

Future changes in financial accounting standards may cause adverse, unexpected fluctuations in the timing of the recognition of revenue or expenses and may affect our financial position or results of operations. New pronouncements and varying interpretations of pronouncements have occurred with frequency and may occur in the future and we may make changes in our accounting policies in the future. Compliance with changing regulation of corporate governance and public disclosure may result in additional expenses. Changing laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act of 2002, new SEC regulations, the Public Company Accounting Oversight Board, pronouncements and The NASDAQ Global Market rules, are creating uncertainty for companies such as ours and insurance, accounting and auditing costs are increasing as a result of this uncertainty and other factors. We are committed to maintaining high standards of corporate governance and public disclosure. As a result, we intend to invest all reasonably necessary resources to comply with evolving standards, and this investment may result in increased general and administrative expenses and a diversion of management time and attention from revenue-generating activities to compliance activities.

A. P. PHARMA  •  2007 ANNUAL REPORT  •  32

We could be exposed to significant product liability claims that could be time consuming and costly to defend, divert management attention and adversely impact our ability to obtain and maintain insurance coverage

The testing, manufacture, marketing and sale of our products involve an inherent risk that product liability claims will be asserted against us. Although we are insured against such risks up to an annual aggregate limit in connection with clinical trials and commercial sales of our products, our present product liability insurance may be inadequate and may not fully cover the costs of any claim or any ultimate damages we might be required to pay. Product liability claims or other claims related to our products, regardless of their outcome, could require us to spend significant time and money in litigation or to pay significant damages. Any successful product liability claim may prevent us from obtaining adequate product liability insurance in the future on commercially desirable or reasonable terms. In addition, product liability coverage may cease to be available in sufficient amounts or at an acceptable cost. An inability to obtain sufficient insurance coverage at an acceptable cost or otherwise to protect against potential product liability claims could prevent or inhibit the commercialization of our products. A product liability claim could also significantly harm our reputation and delay market acceptance of our products.

Our use of hazardous materials could subject us to liabilities, fines and sanctions.

Our laboratory and clinical testing sometimes involve use of hazardous and toxic materials. We are subject to federal, state and local laws and regulations governing how we use, manufacture, handle, store and dispose of these materials. Although we believe that our safety procedures for handling and disposing of such materials comply in all material respects with all federal, state and local regulations and standards, there is always the risk of accidental contamination or injury from these materials. In the event of an accident, we could be held liable for any damages that result and such liability could exceed our financial resources. Compliance with environmental and other laws may be expensive and current or future regulations may impair our development or commercialization efforts.

Risks Related To Our Common Stock

The price of our common stock has been and may continue to be volatile.

Our common stock has historically been volatile, with a trading price ranging from $1.32 to $17.80 over the past five years. The stock markets in general, and the markets for drug delivery and pharmaceutical stocks in particular, have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our common stock. In addition, the limited trading volume of our stock may contribute to its volatility.

Price declines in our common stock could result from general market and economic conditions and a variety of other factors, including:

•  continuing losses and failure to achieve or maintain profitability;

•  our ability to raise capital;

33  •  A. P. PHARMA  •  2007 ANNUAL REPORT

•  adverse results, lack of success or delays in our clinical trials of our product candidates, including APF530;

•  non-approval of our product candidates, or delays in the FDA review process;

•  adverse actions taken by regulatory agencies with respect to our product candidates, clinical trials, manufacturing processes or sales and marketing activities;

•  delays in preclinical and clinical testing;

•  failure to substantiate the capability of our drug delivery technology;

•  failure to attain adequate market acceptance by healthcare professionals and patients;

•  failure of our contract manufacturers and collaborators to perform as expected;

•  failure to comply with continuing federal, state and foreign regulations;

•  market conditions relating to our segment of the industry or the securities markets in general;

•  any lawsuit involving us or our product candidates;

•  announcements concerning our competitors, or the biotechnology or pharmaceutical industries in general;

•  changes in accounting principles; and

•  loss of any of our key scientific or management personnel.

In the past, following periods of volatility in the market price of a particular company’s securities, litigation has often been brought against that company. If litigation of this type is brought against us, it could be extremely expensive and divert management’s attention and our company’s resources.

Our common stock may be delisted from The NASDAQ Global Market, which could negatively impact the price of our common stock and our ability to access the capital markets.

Our common stock is listed on The NASDAQ Global Market. The listing standards of The NASDAQ Global Market provide that a company may be delisted if the closing bid price of its stock drops below $1.00 for a period of 30 consecutive business days. There is a 6 month period to cure, if the closing bid price is over $1.00 for 10 consecutive days within 6 months of the initial 30 day period below $1.00. Additionally, issuers must maintain either (i) stockholders’ equity of at least $10 million or (ii) total assets and total revenue of at least $50 million, or total market value of listed securities of at least $50 million. As of the end of the third fiscal quarter of 2005, we failed to meet the $10 million stockholders’ equity requirement, although we regained compliance with that requirement in January 2006. In early 2007 we again failed to meet the $10 million stockholders’ equity requirement, and were so notified by NASDAQ in May, 2007. Following our public offering of common stock in June, 2007, we

A. P. PHARMA  •  2007 ANNUAL REPORT  •  34

regained compliance, which was subsequently confirmed by NASDAQ. Going forward should we again fail to comply with all listing standards applicable to issuers listed on The NASDAQ Global Market, our common stock may be delisted from The NASDAQ Global Market. If our common stock is delisted, it could reduce the price of our common stock and the levels of liquidity available to our stockholders. In addition, the delisting of our common stock could materially adversely affect our access to the capital markets, and any limitation on liquidity or reduction in the price of our common stock could materially adversely affect our ability to raise capital on terms acceptable to us or at all. Delisting from The NASDAQ Global Market could also result in other negative implications, including the potential loss of confidence by suppliers, customers and employees, the loss of institutional investor interest and fewer business development opportunities.

Our certificate of incorporation, our bylaws, Delaware law and our stockholder rights plan contain provisions that could discourage another company from acquiring us and may prevent attempts by our stockholders to replace or remove our current management.

Provisions of Delaware law, our certificate of incorporation, bylaws and stockholder rights plan may discourage, delay or prevent a merger or acquisition that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares. In addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or remove our board of directors. These provisions include:

•  authorizing the issuance of “blank check” preferred stock without any need for action by stockholders; and

•  providing for dilutive issuance of preferred stock, commonly referred to as a “poison pill”, which can be triggered after a person or a group acquires 20% or more of our common stock.

In addition, Section 203 of Delaware General Corporation Law may discourage, delay or prevent a change in control of our company by prohibiting stockholders owning in excess of 15% of our outstanding voting stock from merging or combining with us, unless certain approvals are obtained.

ITEM 3. LEGAL PROCEEDINGS

While the Company is not currently a party to any material pending legal proceedings, from time to time the Company is named as a party to lawsuits in the normal course of its business.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Annual Report on Form 10-K contains “forward-looking statements” as defined by the Private Securities Litigation Reform Act of 1995. These forward-looking statements involve risks and uncertainties including uncertainties associated with timely development, approval, launch and acceptance of new products, satisfactory completion of clinical studies, establishment of new corporate alliances, progress in research and development programs and other risks and uncertainties identified below and in Item 1A “Risk Factors,” herein. We caution investors that forward-looking statements reflect our analysis only on their stated date. We do not intend to update them except as required by law.

Overview

We are a specialty pharmaceutical company focused on developing pharmaceutical products using our proprietary Biochronomer polymer-based drug delivery technology. Our product development philosophy is based on incorporating approved therapeutics into our proprietary bioerodible drug delivery technology to create controlled release pharmaceuticals to improve treatments for diseases or conditions. Our lead product candidate, APF530, is currently in a pivotal Phase III clinical trial for the prevention of acute and delayed onset chemotherapy-induced nausea and vomiting, or CINV. We expect to complete enrollment of our pivotal Phase III clinical trial in the second quarter of 2008 and to announce results of that trial in the third quarter of 2008. We expect to submit our new drug application, or NDA, for approval of APF530 in the fourth quarter of 2008.

Our primary focus is to advance our proprietary Biochronomer technology, consisting of bioerodible polymers designed to release drugs over a defined period. We have completed over 100 in vivo and in vitro studies demonstrating that our Biochronomer technology is potentially applicable to a range of therapeutic areas, including prevention of nausea and vomiting, pain management, control of inflammation and treatment of ophthalmic diseases. We have also completed comprehensive animal and human toxicology studies that have established that our Biochronomer polymers are safe and well tolerated. Furthermore, our Biochronomer technology can be designed to deliver drugs over periods varying from days to several months.

Our lead product candidate, which utilizes our proprietary Biochronomer technology, is APF530. APF530 is designed to prevent CINV for at least five days and contains granisetron, a drug approved for the prevention of CINV. In September 2005, we completed a Phase II clinical trial of APF530 that achieved all of its primary and secondary endpoints. In May 2006, we initiated our pivotal Phase III clinical trial of AFP530. We believe that this clinical trial will lead to regulatory approval of APF530 for the prevention of acute and delayed onset CINV for patients undergoing both moderately and highly emetogenic, or vomit-inducing, chemotherapy.

A. P. PHARMA  •  2007 ANNUAL REPORT  •  40

In addition to our lead drug candidate, we have a pipeline of other product candidates that use our Biochronomer technology. One of these, APF112, incorporates the well-known local anesthetic, mepivacaine. It is designed to provide up to 36 hours of post-surgical pain relief and to minimize the use of morphine-like drugs, or opiates, which are used extensively in post-surgical pain management. Post-surgical pain can be treated with local anesthetics, but the usefulness of these is currently limited by the short duration of their effectiveness. We plan to initiate a Phase IIb clinical trial for APF112 in the second quarter of 2008.

We have several additional product candidates using our Biochronomer technology in early stages of development. For example, we plan to initiate a Phase I clinical trial of APF580 in the second quarter of 2008 for the controlled delivery of an opiate for pain relief.

Critical Accounting Policies and Estimates

Our accounting policies are more fully described in Note 2 of the Financial Statements. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires our management to make estimates and assumptions about future events that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ significantly from those estimates. We believe the following policies to be critical to understanding our financial condition, results of operations, and expectations for 2008, because these policies require management to make significant estimates, assumptions and judgments about matters that are inherently uncertain.

•  Revenue Recognition

Our revenue arrangements with multiple deliverables are divided into separate units of accounting if certain criteria are met, including whether the delivered item has stand-alone value to the customer and whether there is objective and reliable evidence of the fair value of the undelivered items. The consideration we receive is allocated among the separate units based on their respective fair values, and the applicable revenue recognition criteria are considered separately for each of the separate units. Advance payments received in excess of amounts earned are classified as deferred revenue until earned.

•  Royalties

Contractually required minimum royalties are recorded ratably throughout the contractual period. Royalties in excess of minimum royalties are recognized as earned when the related product is shipped to the end customer by our licensees based on information provided to us by our licensees.

•  Contract Revenue

Contract revenue relates to research and development arrangements that generally provide for us to invoice research and development fees based on full-time equivalent hours for each project. Revenue from these arrangements are recognized as the related development services are rendered. This revenue approximates the costs incurred.

41  •  A. P. PHARMA  •  2007 ANNUAL REPORT

•  Clinical Trial Accruals

Our expenses related to clinical trials are based on estimates of the services received and efforts expended pursuant to contracts with multiple research institutions and clinical research organizations that conduct and manage clinical trials on our behalf. Since the invoicing related to these services does not always coincide with our financial statement close process, we must estimate the level of services performed and fees incurred in determining the accrued clinical trial costs. The financial terms of these agreements are subject to negotiation and variation from contract to contract and may result in uneven payment flows. Payments under the contracts depend on factors such as the successful enrollment of patients or achievement of certain events or the completion of portions of the clinical trial or similar conditions. The Phase III clinical trials of APF530 have a significant effect on the Company’s research and development expenses. Expenses related to clinical trials generally are accrued based on the level of patient enrollment and services performed by the clinical research organization or related service provider according to the protocol. We monitor patient enrollment levels and related activity to the extent possible and adjust our estimates accordingly. Historically these estimates have been accurate and no material adjustments have had to be made.

•  Income Taxes

We make certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of certain tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expense for tax and financial statement purposes. As part of the process of preparing our financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves us estimating our current tax exposure under the most recent tax laws and assessing temporary differences resulting from differing treatment of items for tax and accounting purposes.

We assess the likelihood that we will be able to recover our deferred tax assets. We consider all available evidence, both positive and negative, including our historical levels of income and losses, expectations and risks associated with estimates of future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for a valuation allowance. If we do not consider it more likely than not that we will recover our deferred tax assets, we will record a valuation allowance against the deferred tax assets that we estimate will not ultimately be recoverable. At December 31, 2007, we believed that the amount of our deferred income taxes would not be ultimately recovered. Accordingly, we recorded a full valuation allowance for deferred tax assets. However, should there be a change in our ability to recover our deferred tax assets, we would recognize a benefit to our tax provision in the period in which we determine that it is more likely than not that we will recover our deferred tax assets.

•  Stock-Based Compensation

On January 1, 2006, we adopted the provisions of Statement of Financial Accounting Standards No. 123R, “Share-Based Payment” (SFAS 123R). SFAS 123R revised SFAS 123, “Accounting for Stock-Based Compensation” and supersedes APB Opinion No. 25, “Accounting for Stock Issued to Employees.” SFAS 123R requires companies to measure and recognize compensation expense for all employee share-based payments at fair value over the service period underlying the arrangement. Accordingly, we are required to record the grant-date fair value of stock options issued to employees and purchase-date fair value of employee stock purchases. We adopted SFAS 123R using the “modified prospective” method, whereby fair value of all previously-granted employee share-based arrangements remaining unvested at January 1, 2006, based on the grant-date

A. P. PHARMA  •  2007 ANNUAL REPORT  •  42

value estimated in accordance with the pro forma provisions of SFAS 123, and all grants made on or after January 1, 2006, based on fair value estimated in accordance with SFAS 123(R), have been included in our determination of share-based compensation expense in 2007 and 2006. We have not restated our operating results in prior periods to reflect charges for the fair value of share-based arrangements.

Prior to January 1, 2006 we elected to account for stock-based compensation related to employees using the intrinsic value method. Accordingly, except for stock options issued to non-employees and restricted stock awards to employees and directors, no compensation cost was recognized for our stock option plans and stock purchase plan because stock option exercise prices historically equaled the per share fair values of the underlying common stock. Compensation related to options granted to non-employees was periodically re-measured as earned.

Revenue

We had no royalty revenue in 2007 and 2006, reflecting the sale of our rights to royalties on sales of Retin-A Micro and Carac on January 18, 2006, on which we recorded a gain of $23,429,000 (see Note 12). Royalties were $5,247,000 in 2005, mainly from royalties on sales of Carac, a topical prescription treatment for actinic keratoses which is sold by our marketing partner, Dermik Laboratories, a Sanofi-Aventis company and royalties on sales of Retin-A Micro, a topical prescription treatment for acne which is marketed by Ortho Neutrogena, a Johnson & Johnson company.

43  •  A. P. PHARMA  •  2007 ANNUAL REPORT

Contract revenue increased in 2007 by $412,000 or 100% from $0 in 2006 a result of a collaborative research and development program with a major animal health company (See Note 12). Contract revenue decreased in 2006 by $144,000 or 100% from $144,000 in 2005 as a result of no collaborative research and development programs as we focused our efforts on the development of APF530 for the prevention of both acute and delayed chemotherapy-induced nausea and vomiting.

Research and Development

Research and development expense in 2007 increased by $4,128,000 or 27% to $19,364,000 from $15,236,000 in 2006 due mainly to our Phase III clinical trial for APF530. Research and development expense in 2006 increased by $4,937,000 or 48% to $15,236,000 from $10,299,000 in 2005 due mainly to our Phase III clinical trial for APF530. Research and development expenses in 2008 are expected to increase over those incurred in 2007, reflecting costs to be incurred for clinical trials of APF112 and APF580, added research and development personnel to support the expanded clinical trial activities, with some offset from reduced APF530 trial expenses.

The scope and magnitude of future research and development expenses are difficult to predict given the number of studies that will need to be conducted for any of our potential products. In general, biopharmaceutical development involves a series of steps, beginning with identification of a potential target, and includes proof of concept in animals and Phase I, II and III clinical studies in humans. Each step of this process is typically more expensive than the previous one, so success in development results in increasing expenditures.

We have a number of product candidates in various stages of development. The following table sets forth the current opportunities for our own portfolio of product candidates, the compound selected, the delivery duration and the status.

Product Portfolio	Drug	Targeted Duration	Status
APF530—Anti-nausea (chemotherapy)	Granisetron	At least five days	Phase III
APF112—Acute pain relief (surgical/orthopedic)	Mepivacaine	Up to 36 hours	Phase II
APF580—Pain relief	Undisclosed opiate	At least seven days	Preclinical
APF328—Anti-inflammatory (surgical/orthopedic)	Meloxicam	Up to two weeks	Preclinical
APF505—Anti-inflammatory (osteoarthritis)	Meloxicam	Up to six weeks	Preclinical

The major components of research and development expenses for 2007, 2006 and 2005 were as follows (in thousands):

For the year December 31,	2007		2006		2005
Internal research and development costs	$	6,264	$	6,455	$	5,197
External development costs:
APF530		12,137		7,305		3,551
APF112		—		—		—
External general technology development costs		963		1,476		1,551
	$	19,364	$	15,236	$	10,299

A. P. PHARMA  •  2007 ANNUAL REPORT  •  44

Internal research and development costs consist of employee salaries and benefits, laboratory supplies, depreciation, and allocation of overhead. External general technology development costs include expenditures on polymer development and manufacturing, which are performed on our behalf by third parties.

General and Administrative

General and administrative expense increased by $1,053,000 or 29% in 2007 to $4,681,000 from $3,628,000 in 2006 due primarily to severance costs recorded in 2007 related to the departure of Michael O’Connell, our former Chief Financial Officer and Chief Operating Officer. General and administrative expense increased by $63,000 or 2% in 2006 to $3,628,000 from $3,565,000 in 2005. General and administrative expense consists of salaries and related expenses, professional fees, directors’ fees, investor relations costs, insurance expense and the related overhead cost allocation. General and administrative expense for 2008 is expected to decline from the 2007 level due to the absence of the severance costs, with such expense reductions offset somewhat by costs associated with executive recruitment activities.

Interest Income

Interest income consists primarily of income earned on our invested cash, cash equivalents and marketable securities. Interest income increased by $320,000 in 2007 to $1,326,000 compared to $1,006,000 in 2006 due to a higher level of invested assets, as a result of our June 2007 financing. Interest income increased by $719,000 in 2006 to $1,006,000 compared to $287,000 in 2005 due to a higher level of invested assets and higher interest rates.

Discontinued Operations

On February 13, 2003, we completed the sale of certain assets of our Analytical Standards division to GFS Chemicals, Inc. (“GFS”), a privately held company based in Columbus, Ohio. In this transaction, we received $2.1 million on closing, and are entitled to receive royalties on sales of Analytical Standards products for a period of five years following the sale at rates ranging from 15% to 5%. The net present value of the guaranteed minimum royalties is included in the gain on disposition of these assets.

On July 25, 2000, we completed the sale of certain technology rights for our topical pharmaceutical and cosmeceutical product lines and associated assets, referred to as our cosmeceutical and toiletry business, to RP Scherer Corporation, a subsidiary of Cardinal Health, Inc. We received $25 million at closing and were entitled to receive further earnout amounts for the subsequent three years, the amounts of which were dependent on the performance of the business sold.

Under the terms of the agreement with RP Scherer, we guaranteed a minimum gross profit percentage on RP Scherer’s combined sales of products to Ortho Neutrogena and Dermik (“Gross Profit Guaranty”). The guaranty period commenced on July 1, 2000 and ends on the earlier of July 1, 2010 or the end of two consecutive guaranty periods where the combined gross profit on sales to Ortho and Dermik equals or exceeds the guaranteed gross profit (the “two period test”). The Gross Profit Guaranty expense totaled $944,000 for the first seven guaranty years and in those years profits did not meet the two period test. Effective March 2007, in conjunction with a sale of assets by RP Scherer’s successor company to an Amcol International subsidiary (“Amcol”), a new agreement was signed between us and Amcol to provide continuity of product supply to Ortho and

45  •  A. P. PHARMA  •  2007 ANNUAL REPORT

Dermik. This new agreement potentially extends the gross profit guaranty period an additional three years to July 1, 2013 unless it is terminated earlier with the two period test. Therefore, we expect the annual Gross Profit Guaranty payment to range from $100,000 to $200,000 for the remainder of the guaranty period.

Loss from discontinued operations represents primarily the loss attributable to the Gross Profit Guaranty associated with the sale of our cosmeceutical and toiletry business. For the year 2007, the increased level of loss from prior years represents the amount of the guaranty as asserted by Amcol, which remains subject to challenge by us.

The gain on disposition of discontinued operations recorded in 2007 of $20,000 compared to $56,000 in 2006 and $62,000 in 2005 and relates to the gain on the sale of our Analytical Standards division as measured by royalty receipts in excess of guaranteed minimums.

Liquidity and Capital Resources

Cash, cash equivalents and marketable securities increased by $19,540,000 to $35,062,000 at December 31, 2007 from $15,522,000 at December 31, 2006, primarily as a result of our June 2007 financing offset by cash used to fund our operations.

Net cash used in continuing operating activities for the year ended December 31, 2007 was $17,112,000 and related primarily to funding operations offset by changes in accrued expenses and accounts payable, as well as depreciation, amortization and stock-based compensation. The increase in net cash used in continuing operating activities in 2007, as compared to 2006, was primarily due to the gain of $ 2.5 million in 2007 as compared to $23.4 million in 2006 from the sale of our rights to royalties on sales of Retin-A Micro and Carac, and additional research and development expenses in 2007 associated with the Phase III study of APF530.

Net cash provided by continuing operating activities for the year ended December 31, 2006 was $9,157,000 and related primarily to income from operations, including the $23.4 million gain on sale of Retin-A Micro and Carac royalty interest, changes in operating assets and liabilities, as well as stock based compensation and depreciation and amortization.

Net cash used in continuing operating activities was $7,652,000 for the year ended December 31, 2005 and primarily related to funding operations, offset by depreciation and amortization and stock based compensation.

The cash used in discontinued operations of $169,000 in 2007 related to Gross Profit Guaranty payments to RP Scherer, partially offset by the royalties received from GFS for sales of Analytical Standards products. The cash provided by discontinued operations of $24,000 and $125,000 in 2006 and 2005, respectively, related to the royalties received from GFS for sales of Analytical Standards products, partially offset by severance payments and payments of the Gross Profit Guaranty to RP Scherer.

Net cash provided by investing activities for the year ended December 31, 2007 was $11,202,000 compared with net cash used in investing activities for the year ended December 31, 2006 of $7,717,000 and net cash provided by investing activities of $5,088,000 in the year ended December 31, 2005. The increase in net cash provided by investing activities in 2007 compared with net cash used in investing activities in 2006 was primarily due to our leaving cash and cash proceeds from maturities and sales of marketable securities in cash and cash equivalents rather than investing in marketable securities. The increase

A. P. PHARMA  •  2007 ANNUAL REPORT  •  46

in net cash used in investing activities in 2006 compared with net cash provided by investing activities in 2005 was primarily due to increased purchases of marketable securities and decreased maturities of marketable securities.

Our financing activities provided us with $37,256,000, $79,000 and $119,000 for the years ended December 31, 2007, 2006 and 2005, respectively. The net cash provided by financing activities in 2007 primarily related to the issuance of 24,393,939 shares of common stock at $1.65 per share for net proceeds of $37.2 million in June 2007. The net cash provided by financing activities in 2006 and 2005 primarily related to proceeds from issuances of shares under the Employee Stock Purchase Plan and stock option plans.

We have financed our operations including technology and product research and development, primarily through royalties received on sales of Retin-A Micro and Carac, the sale of our rights to royalties on sales of Retin-A Micro and Carac, income from collaborative research and development fees, proceeds received from the sales of our Analytical Standards division and our cosmeceutical and toiletry business, sales of common stock, and interest earned on short-term investments. Our cash, cash equivalents and marketable securities at December 31, 2007 are expected to be sufficient to meet our cash needs at least through 2008. It is probable that we will seek additional financing within this timeline through convertible debt or equity financing, collaborative agreements or other arrangements.

Our capital requirements going forward from 2008 will depend on numerous factors including, among others, our ability to enter into collaborative research and development and licensing agreements; progress of product candidates in preclinical and clinical trials; investment in new research and development programs; time required to gain regulatory approvals; resources that we devote to self-funded products; potential acquisitions of technology, product candidates or businesses; and the costs of defending or prosecuting any patent opposition or litigation necessary to protect our proprietary technology.

There can be no assurance that we will be able to raise sufficient additional capital when we need it or to raise capital on favorable terms. The sale of additional equity or convertible debt securities in the future may be dilutive to our stockholders, and debt financing arrangements may require us to pledge certain assets and enter into covenants that could restrict certain business activities or our ability to incur further indebtedness and may contain other terms that are not favorable to us or our stockholders. If we are unable to obtain adequate funds on reasonable terms, we may be required to curtail operations significantly or to obtain funds by entering into financing, supply or collaboration agreements on unattractive terms.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Our exposure to market rate risk for changes in interest rates relates primarily to our investment portfolio. We do not use derivative financial instruments. We manage our interest rate risk by maintaining an investment portfolio primarily consisting of debt instruments of high credit quality and relatively short average maturities. The interest rates as of December 31, 2007 and 2006 were 5.0% and 5.1%, respectively. At December 31, 2007 and 2006, respectively, our cash equivalents and marketable securities include corporate and other debt securities as follows: (in thousands)

December 31,	2007		2006
Available-for-sale:
Due in less than 1 year	$	33,430	$	14,665
Due after 1 year but less than 5 years		976		400
Total available-for-sale	$	34,406	$	15,065

Notwithstanding our efforts to manage interest rate risks, there can be no assurance that we will be adequately protected against the risks associated with interest rate fluctuations.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

A.P. Pharma, Inc.

We have audited the accompanying balance sheets of A.P. Pharma, Inc. as of December 31, 2007 and 2006 and the related statements of operations, stockholders’ equity and cash flows for the years then ended. Our audits also included the 2007 and 2006 financial data in the financial statement schedule listed in the Index at Item 15(a)2. These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements audited by us present fairly, in all material respects, the financial position of A.P. Pharma, Inc. at December 31, 2007 and 2006, and the results of its operations and its cash flows for the years then ended, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule for the years ended December 31, 2007 and 2006, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

As discussed in Note 11, on January 1, 2007, the Company adopted Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an Interpretation of FAS 109. Also, as discussed in Note 2, the Company adopted SFAS No. 123(R), Share-Based Payment, applying the modified prospective method effective January 1, 2006.

Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company’s internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audit provides a resonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the results of operations and cash flows of A.P. Pharma, Inc. for the year ended December 31, 2005, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule for the year ended December 31, 2005, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2007, 2006 AND 2005

NOTE 1 BUSINESS

We are a specialty pharmaceutical company focused on developing pharmaceutical products using our proprietary Biochronomer polymer-based drug delivery technology. Our product development philosophy is based on incorporating approved therapeutics into our proprietary bioerodible drug delivery technology to create controlled release pharmaceuticals to improve treatments for diseases or conditions. Our lead product candidate, APF530, is currently in a pivotal Phase III clinical trial for the prevention of acute onset and delayed onset chemotherapy-induced nausea and vomiting, or CINV. We expect to complete enrollment of our pivotal Phase III clinical trial in the second quarter of 2008 and to announce results of that trial in the third quarter of 2008. We expect to submit our new drug application, or NDA, for approval of APF530 in the fourth quarter of 2008.

Our primary focus is to advance our proprietary Biochronomer technology, consisting of bioerodible polymers designed to release drugs over a defined period. We have completed over 100 in vivo and in vitro studies demonstrating that our Biochronomer technology is potentially applicable to a range of therapeutic areas, including prevention of nausea, pain management, control of inflammation and treatment of ophthalmic diseases. We have also completed comprehensive animal and human toxicology studies that have established that our Biochronomer polymers are safe and well tolerated. Furthermore, our Biochronomer technology can be designed to deliver drugs over periods varying from days to several months.

On July 25, 2000, we completed the sale of certain technology rights for our topical pharmaceutical and cosmeceutical product lines and other assets (“cosmeceutical and toiletry business”) to RP Scherer Corporation, a subsidiary of Cardinal Health, Inc. As a result of this transaction, our Statements of Operations reflect the payment of certain contractual obligations in the loss from discontinued operations (see Note 9).

On February 13, 2003, we completed the sale of our Analytical Standard division to GFS Chemicals, Inc. (“GFS”), a privately held company based in Columbus, Ohio. In this transaction, we received $2.1 million and are entitled to receive royalties on sales of Analytical Standards products of 15% for the first year, 10% for the second through fourth years, and 5% for the fifth year. The net present value of the guaranteed minimum royalties is included in the gain on disposition of discontinued operations (see Note 9).

On January 18, 2006 we sold our rights to royalties on sales of Retin-A Micro(R) and Carac (R), effective October 1, 2005, for up to $30 million. Proceeds of $25 million were received upon the closing of the transaction and used primarily to fund pivotal clinical development of APF530, our drug candidate for the prevention of both acute and delayed chemotherapy-induced nausea and vomiting. The remaining $5 million was to be received upon the achievement of certain milestones over the successive four years. Upon attainment of one milestone in 2007, an additional $2.5 million was received. The remaining $2.5 million will be paid based on the satisfaction of certain other predetermined milestones over the next two years (see Note 12). In 2007 and 2006, we recognized a gain on the sale of the royalty interest of $2.5 million and $23.4 million, respectively.

On October 1, 2006, we entered into an agreement with RHEI Pharmaceuticals, Inc. (“RHEI”) in which we granted RHEI exclusive license to develop and market APF530 in Greater China (See Note 12).

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2007, 2006 AND 2005

Reverse stock split

On May 23, 2007, we filed a Certificate of Amendment to our Certificate of Incorporation with the Secretary of State of the State of Delaware effecting a 1-for-4 reverse stock split of our common stock. All share and per share amounts for all periods presented have been retroactively restated to reflect the reverse stock split.

NOTE 2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Cash Equivalents and Marketable Securities

We consider all debt securities that have original maturities, from the date of purchase, of less than three months to be cash equivalents. Investments with maturities of three months and longer from the date of purchase are classified as marketable securities. Investments consist primarily of government obligations, mortgage backed securities, municipal bonds and corporate debt securities. We account for our marketable securities in accordance with SFAS115, Accounting for Certain Investments in Debt and Equity Securities. We have classified all our investments in certain debt securities as “available-for-sale”, and, therefore, they are recorded at fair value with unrealized gains and losses reported as a separate component of stockholders’ equity. If the estimated fair value of a security is below its carrying value, we evaluate whether we have the intent and ability to retain our investment for a period of time sufficient to allow for any anticipated recovery in market value and whether evidence indicating that the cost of the investment is recoverable within a reasonable period of time outweighs evidence to the contrary. If the impairment is considered to be other-than-temporary, the security is written down to its estimated fair value. Other-than-temporary declines in estimated fair value of all marketable securities are charged to “other income (loss), net.” The cost of all securities sold is based on the specific identification method.

Financial Instruments

The carrying values of the Company’s financial instruments, including marketable securities, accounts receivable and accrued liabilities, approximate their respective fair values due to their short maturities.

Allowance for Note Receivable

A 100% allowance of $394,000 was recorded for a note receivable at such time as management determined that collection was not reasonably assured. Interest income under the terms of the note receivable agreement is recorded when cash is received or collectibility is reasonably assured. The note receivable, net of the related allowance, is included in prepaid expenses and other current assets in the accompanying balance sheets.

Property and Equipment

Property and equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as follows: equipment and machinery, 3 to 5 years; furniture and fixtures, 5 years; and leasehold improvements, over the shorter of the respective lease terms or the respective useful lives of the leasehold improvements.

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2007, 2006 AND 2005

Long-Lived Assets

As circumstances dictate, we evaluate whether changes have occurred that would require us to consider whether those assets have been impaired. Recoverability of assets to be held and used is determined by comparing the undiscounted net cash flows of long-lived assets to their respective carrying values. If such assets are considered to be impaired, the amount of impairment to be recognized is measured based on the projected discounted cash flows using an appropriate discount rate.

Stock-Based Compensation

On January 1, 2006, we adopted the provisions of Statement of Financial Accounting Standards No. 123R, “Share-Based Payment” (SFAS 123R). SFAS 123R revised SFAS 123, “Accounting for Stock-Based Compensation” and supersedes APB Opinion No. 25, “Accounting for Stock Issued to Employees.” SFAS 123R requires companies to measure and recognize compensation expense for all employee share-based payments at fair value over the service period underlying the arrangement. Accordingly, we are required to record the grant-date fair value of stock options issued to employees and purchase-date fair value of employee stock purchases. We adopted SFAS 123R using the “modified prospective” method, whereby fair value of all previously-granted employee share-based arrangements remaining unvested at January 1, 2006, based on the grant-date value estimated in accordance with the pro forma provisions of SFAS 123, and all grants made on or after January 1, 2006, based on fair value estimated in accordance with SFAS 123(R), have been included in our determination of share-based compensation expense in 2007 and 2006. We have not restated our operating results in prior periods to reflect charges for the fair value of share-based arrangements.

In November 2005, the FASB issued FASB Staff Position No. SFAS 123(R)-3 “Transition Election Related to Accounting for Tax Effects of Share-Based Payment Awards” (FSP 123(R)-3). The Company adopted the alternative transition method provided in the FASB Staff Position for calculating the tax effects of stock-based compensation pursuant to SFAS 123(R) in the fourth quarter of fiscal 2006. The alternative transition method includes simplified methods to establish the beginning balance of the additional paid-in capital pool (APIC pool) related to the tax effects for employee stock-based compensation, and to determine the subsequent impact on the APIC pool and Consolidated Statements of Cash Flows of the tax effects of employee stock-based compensation awards that are outstanding upon adoption of SFAS 123(R). The adoption did not have a material impact on our results of operations and financial condition.

Prior to January 1, 2006 we elected to account for stock-based compensation related to employees using the intrinsic value method. Accordingly, except for stock options issued to non-employees and restricted stock awards to employees and directors, no compensation cost was recognized for our stock option plans and stock purchase plan because stock option exercise prices historically equaled the per share fair values of the underlying common stock. Compensation related to options granted to non-employees was periodically remeasured as earned.

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2007, 2006 AND 2005

In accordance with SFAS No. 123, “Accounting for Stock-Based Compensation,” as amended by SFAS No. 148, “Accounting for Stock-Based Compensation-Transition and Disclosure,” we have provided, below, the pro forma disclosures of the effect on net loss and net loss per share as if SFAS No. 123 had been applied in measuring compensation expense for the year ended December 31, 2005 (in thousands, except for per share amounts) (see Note 7 “Stockholders’ Equity”):

Basic and diluted net loss per common share—as reported	$	(1.31	)
Basic and diluted net loss per common share—pro-forma	$	(1.36	)

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Estimates were made relating to useful lives of fixed assets, valuation allowances, impairment of assets, accruals for research and development expenses, and share-based costs. Actual results could differ materially from those estimates.

Revenue Recognition

Our revenue arrangements with multiple deliverables are divided into separate units of accounting if certain criteria are met, including whether the delivered item has stand-alone value to the customer and whether there is objective and reliable evidence of the fair value of the undelivered items. The consideration we receive is allocated among the separate units based on their respective fair values, and the applicable revenue recognition criteria are considered separately for each of the separate units. Advance payments received in excess of amounts earned are classified as deferred revenue until earned.

Royalties

Royalties from licenses are based on third-party sales of licensed products or technologies and recorded as earned in accordance with contract terms when third-party results can be reliably determined and collectibility is reasonably assured.

Generally, contractually required minimum royalties are recorded ratably throughout the contractual period. Royalties in excess of minimum royalties are recognized as earned when the related product is shipped to the end customer by our licensees based on information provided to us by our licensees.

A. P. PHARMA  •  2007 ANNUAL REPORT  •  58

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2007, 2006 AND 2005

Contract Revenue

Contract revenue relates to research and development arrangements that generally provide for us to invoice research and development fees based on full-time equivalent hours for each project. Revenue from these arrangements is recognized as the related development services are rendered. This revenue approximates the costs incurred.

Research and Development

Research and development consists of costs incurred for Company-sponsored and collaborative research and development expenses. These costs consist primarily of employee salaries and other personnel-related expenses, facility-related expenses, lab consumables, polymer development manufacturing, clinical and pre-clinical related services performed by clinical research organizations, research institutions and other outside service providers.

Expenses related to clinical trials generally are accrued based on the level of patient enrollment and services performed by the clinical research organization or related service provider according to the protocol. We monitor patient enrollment levels and related activity to the extent possible and adjusts estimates accordingly.

Research and development expenses under collaborative agreements approximate the revenue recognized, excluding milestone and up-front payments received under such arrangements.

Net Income (Loss) Per Share

Basic income (loss) per share is estimated based on the weighted-average number of common shares outstanding. Diluted earnings per share is calculated using the weighted-average number of common shares outstanding and other dilutive securities (See Note 8).

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash equivalents, short-term investments and trade accounts receivable. We invest excess cash in a variety of high grade short-term, interest-bearing securities. This diversification of risk is consistent with our policy to ensure safety of principal and maintain liquidity.

Segment and Geographic Information

Our operations are confined to a single business segment, the design and commercialization of polymer technologies for pharmaceutical and other applications. Substantially all of our revenue are derived from customers within the United States.

Recent Accounting Pronouncements

In September 2006, the Financial Accounting Standards Board (“FASB”) issued SFAS 157, Fair Value Measurements (“SFAS157”), which establishes a framework for measuring fair value in generally accepted accounting principles, and expands

59  •  A. P. PHARMA  •  2007 ANNUAL REPORT

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2007, 2006 AND 2005

disclosures about fair value measurements. SFAS 157 does not require any new fair value measurements, but provides guidance on how to measure fair value by providing a fair value hierarchy used to classify the source of the information. SFAS 157 is effective for fiscal years beginning after November 15, 2007. However, on December 14, 2007, the FASB issued proposed FSP FAS 157-b which would delay the effective date of SFAS 157 for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). This proposed FSP partially defers the effective date of Statement 157 to fiscal years beginning after November 15, 2008, and interim periods within those fiscal years for items within the scope of this FSP. Effective for 2008 we will adopt SFAS 157 except as it applies to those nonfinancial assets and nonfinancial liabilities as noted in FSP FAS 157-b. The partial adoption of SFAS 157 will not have a material impact on our consolidated financial position, results of operations or cash flows.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities- including an amendment of FASB Statement No. 115 (“SFAS 159”), which allows an entity to choose to measure certain financial instruments and liabilities at fair value. Subsequent measurements for the financial instruments and liabilities an entity elects to fair value will be recognized in earnings. SFAS 159 also establishes additional requirements. SFAS 159 is effective for us beginning January 1, 2008. We have not decided if we will choose to measure eligible financial assets and liabilities at fair value.

In December 2007, the FASB issued SFAS 141 (revised 2007), Business Combinations (“SFAS141R”). SFAS 141R establishes principles and requirements for how an acquirer recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, any noncontrolling interest of the acquiree and the goodwill acquired. SFAS 141R also establishes disclosure requirements to enable the evaluation of the nature and financial effects of the business combination. This statement is effective for us beginning January 1, 2009. We will assess the potential impact of the adoption of SFAS 141R if and when a future acquisition occurs.

On June 27, 2007, EITF 07-3, Accounting for Advance Payments for Goods and Services to be Received for Use in Future Research and Development Activities, was ratified which requires companies to defer and capitalize prepaid nonrefundable research and development payments to third parties until the research and development activities are performed or the services are provided, subject to an assessment of recoverability. The guidance is effective for new contracts entered into in fiscal years beginning after December 15, 2007, including interim periods within those fiscal years. We do not expect that the adoption of this pronouncement will have a material effect on our financial position or results of operations.

NOTE 3 CASH EQUIVALENTS AND MARKETABLE SECURITIES

We consider our investments in debt securities as available-for-sale and, accordingly, we have recorded these investments at fair value. Our marketable securities as of December 31, 2007 consist of highly liquid short term money market funds and asset backed securities with the underlying assets consisting of high quality pools of residential mortgages. All the securities retained AAA ratings as of December 31, 2007. We assessed the decline in the fair value of the asset-backed securities of $38,000 as of December 31, 2007 to be temporary. There were no realized gains or losses for the year ended December 31, 2007. Realized losses totaled $1,000 and $4,000 for the years ended December 31, 2006 and 2005, respectively.

Total rental expense for facilities and equipment was $550,000, $500,000 and $492,000 for 2007, 2006 and 2005, respectively.

As part of the sale of our cosmeceutical and toiletry business to RP Scherer Corporation in July 2000, we guaranteed a minimum gross profit percentage on RP Scherer’s sales of products to Ortho Neutrogena and Dermik (See Note 9 “Discontinued Operations”).

As permitted under Delaware law and in accordance with our bylaws, we indemnify our officers and directors for certain events or occurrences while the officer or director is or was serving at the Company’s request in such capacity. The term of the indemnification period is for the officer’s or director’s lifetime. The maximum amount of potential future indemnification is unlimited; however, we have a director or officer insurance policy that limits our exposure and may enable us to recover a portion of any future amounts paid. We believe the fair value of these indemnification agreements is minimal. Accordingly, we have not recorded any liabilities for these agreements as of December 31, 2007.

In the normal course of business, we provide indemnifications of varying scope under our agreements with other companies, typically our clinical research organizations, investigators, clinical sites, suppliers and others. Pursuant to these agreements, we generally indemnify, hold harmless, and agree to reimburse the indemnified parties for losses suffered or incurred by the indemnified parties in connection with use or testing of our products or product candidates or with any U.S. patent or any copyright or other intellectual property infringement claims by any third party with respect to our products. The term of these indemnification agreements is generally perpetual. The potential future payments we could be required to make under these indemnification agreements is unlimited. Historically, costs related to these indemnification provisions have been immaterial. We also maintain various liability insurance policies that limit our exposure. As a result, we believe the fair value of these indemnification agreements is minimal. Accordingly, we have not recorded any liabilities for these agreements as of December 31, 2007.

NOTE 7 STOCKHOLDERS’ EQUITY

On June 19, 2007, we sold 24,393,939 shares of our common stock in a public offering at a price of $1.65 per share, for net proceeds of approximately $37.2 million after deducting underwriting fees and costs associated with the offering. The shares were offered under our registration statement on Form S-1, as amended (Registration No. 333-14-1918)

Reverse stock split

On May 23, 2007, we filed a Certificate of Amendment to our Certificate of Incorporation with the Secretary of State of the State of Delaware effecting a 1-for-4 reverse stock split of our common stock. All share and per share amounts for all periods presented have been retroactively restated to reflect the reverse stock split.

Shareholders’ Rights Plan

On December 18, 2006, we entered into a Preferred Shares Rights Agreement. As part of this agreement, preferred stock purchase rights (“the rights”) were distributed to stockholders of record as of January 2, 2007 (and to each person who acquires our common stock after that date unless determined otherwise by the board of directors) at the rate of one right for

63  •  A. P. PHARMA  •  2007 ANNUAL REPORT

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2007, 2006 AND 2005

each share of common stock held. The rights become exercisable only upon the acquisition, or the acquisition of the right to acquire, by a person or group of affiliated or associated persons, of 20% or more of the outstanding shares of the Company’s common stock. Once exercisable, each right entitles the holder to purchase, at a price of $44.00, one one-thousandth of a share of Series A Participating Preferred Stock. For a limited period of time following the announcement of any such acquisition or offer, the rights are redeemable by the Company at a price of $0.01 per right. If the rights are not redeemed or exchanged, each right will then entitle the holder to receive, upon exercise of such right, a number of shares of the Company’s common stock having a then current value equal to two times the purchase price of such right. Similarly, if the rights are not redeemed or exchanged and following the acquisition of 20% or more of the outstanding shares of the Company’s common stock by a person or group of affiliated or associated persons, (i) the Company consolidates with or merges into another entity, (ii) another entity consolidates with or merges into the Company or (iii) the Company sells or otherwise transfers 50% or more of its consolidated assets or earning power, each right will then entitle the holder to receive, upon exercise of such right, a number of shares of common stock of the acquiring company having a then current value equal to two times the purchase price. For a limited period of time after the exercisability of the rights, each right, at the discretion of the board of directors, may be exercised for such number of shares of common stock determined in accordance with the rights agreement. The Company has initially reserved 200,000 shares of preferred stock pursuant to the exercise of these rights. These rights expire on December 31, 2016.

Stock-Based Compensation Plans

We have two types of stock-based compensation plans, which consist of a stock purchase plan and three stock option plans.

In 1997, our stockholders approved our 1997 Employee Stock Purchase Plan (the “Plan”). In December 2007 the stockholders authorized the increase in shares reserved for issuance under the Plan by 100,000 to 300,000 to our employees, nearly all of whom are eligible to participate. Under the terms of the Plan, employees can elect to have up to a maximum of 10 percent of their base earnings withheld to purchase our common stock. The purchase price of the stock is 85 percent of the lower of the closing prices for our common stock on: (i) the first trading day in the enrollment period, as defined in the Plan, in which the purchase is made, or (ii) the purchase date. The length of the enrollment period may not exceed a maximum of 24 months. Enrollment dates are the first business day of May and November and the first enrollment date was April 30, 1997. Approximately 43 percent of eligible employees participated in the Plan in 2007. Under the Plan, we issued 22,860 shares in 2007 and 16,175 shares in 2006. The weighted average fair value of purchase rights granted during 2007 and 2006 was $1.82 and $2.60, respectively. The weighted average exercise price of the purchase rights exercised during 2007 and 2006 was $2.52 and $4.20, respectively. We had 133,160 and 55,846 shares reserved for issuance under the Plan at December 31, 2007 and 2006, respectively.

We have three stock option plans currently from which we can grant options to employees, officers, directors and consultants. In December 2007 the stockholders approved our 2007 Equity Incentive Plan (the “2007 Plan”). The Company is authorized to issue up to 3,000,000 shares under the 2007 plan. We also grant stock options under the 2002 Stock Incentive Plan (the “2002 Plan”) and the Non-Qualified Stock Plan. The Company is authorized to issue up to 425,000 shares under the 2002 Plan, 100,000 of which were approved by stockholders in May 2006, and 1,062,500 shares under the Non-Qualified Stock Plan, an inducement option plan, 1,000,000 of which were added to the plan by the board in September 2007. The options to purchase our common stock are granted with an exercise price which equals fair market value of the underlying common stock on the grant dates, and expire no later than ten years from the date of grant. The options are exercisable in accordance with vesting schedules that generally provide for them to be fully vested and exercisable four years after the date of grant. Any

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2007, 2006 AND 2005

shares that are issuable upon exercise of options granted under the 2002 Plan and the Non-Qualified Stock Plan that expire or become unexercisable for any reason without having been exercised in full are available for future grant and issuance under the same stock option plan.

We adopted SFAS 123R, Share-Based Payment, on January 1, 2006. Accordingly, we recorded the grant-date or purchase-date fair value of stock options and purchase rights issued to employees in conjunction with our stock option plans or employee stock purchase plan. We have also recorded compensation expense for stock options issued to non-employees and restricted stock awards to employees and directors.

The fair value of each employee and director grant of options to purchase common stock and purchase rights under the employee stock purchase plan is estimated on the date of the grant using the Black-Scholes option-pricing model assuming no dividends and the following weighted-average assumptions:

	2007	2006
Expected term (years):
Stock options	6.25	6.25
Employee Stock Purchase Plan	1.25	1.25
Risk-free interest rate:
Stock options	4.3%	4.8%
Employee Stock Purchase Plan	3.87%	4.9%
Volatility:
Stock options	240%	240%
Employee Stock Purchase Plan	57%	82%

The expected term of options granted is based on the simplified method provided in Staff Accounting Bulletin No. 107 for “plain vanilla options” and the expected term for the employee stock purchase plan is based on the weighted –average purchase period of the plan The expected volatility is based on the Company’s historical stock prices and the estimated forfeiture rate of the options is based on historical data.

The Black-Scholes option valuation model requires the input of highly subjective assumptions, including the expected life of the award and stock price volatility. The assumptions listed above represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if other assumptions had been used, our recorded and pro forma stock based compensation expense could have been materially different.

The SFAS 123R share-based compensation expenses recorded for awards granted under the stock option plans and employee stock purchase plan were approximately $249,000 and $372,000, net of estimated forfeitures, for the years ended December 31, 2007 and 2006, respectively. The share-based compensation expense of $106,000 and $143,000 was recorded in research and development expense and general and administrative expense for the year ended December 31, 2007, respectively. The share-based compensation expense of $134,000 and $238,000 was recorded in research and development and general and administrative expense for the year ended December 31, 2006, respectively. No tax benefit was recognized related to share-based compensation expense since we have incurred operating losses and we have established a full valuation allowance to offset all the potential tax benefits associated with our deferred tax assets.

We granted options to purchase common stock to consultants from time to time in exchange for services rendered and these options vest over a period of two to four years. No options were granted to consultants in 2007 and 2006. We recorded compensation expense related to option grants to consultants of approximately $2,000 and $4,000 in 2006 and 2005, respectively, which represents the fair market value of the portion of the awards that vested during 2006 and 2005. The unvested shares held by consultants have been revalued using the Black-Scholes option pricing model at the end of each accounting period. As of December 31, 2007, all shares held by consultants have been vested.

In 2006, we granted 10,000 shares of restricted stock awards under the 2002 Plan to employees and directors. As of December 31, 2007, we had a total of 33,750 shares of unvested restricted stock awards granted to employees and directors. The compensation cost that has been expensed in the statements of operations for the restricted stock awards issued to employees and directors was $99,000 and $57,000 for 2007 and 2006, respectively. Also in 2006, we granted our non-employee directors 11,000 shares representing directors’ fees, and recorded $77,000 of expense in our statement of operations.

Fair values of awards granted under the stock option plans and employee stock purchase plan prior to January 1, 2006 were estimated at grant or purchase dates using a Black-Scholes option pricing model. For pro forma disclosure, the estimated fair value of the options is amortized to expense over the vesting period of the options using the straight line method. The multiple option approach is used to value the purchase rights granted under the employee stock purchase plan. We used the following assumptions:

Year Ended December 31,	2005
Expected term (in years):

Employee Stock Purchase Plan	0.5 - 2
Risk-free interest rate:

NOTE 9 DISCONTINUED OPERATIONS

We completed the sale of certain assets of our Analytical Standards division as well as certain technology rights for our topical pharmaceutical and cosmeceutical product lines and other assets (“cosmeceutical and toiletry business”) in February 2003 and July 2000, respectively.

The Analytical Standards division and cosmeceutical and toiletry business are reported as discontinued operations for all periods presented in the accompanying Statements of Operations.

Loss from discontinued operations represents primarily the loss attributable to changes in estimates of our cosmeceutical and toiletry business that was sold to RP Scherer on July 25, 2000, as follows (in thousands):

For the years ended December 31,	2007			2006			2005
Cosmeceutical and Toiletry Business
Change in estimates for severance costs and guarantees	$	(342	)	$	(188	)	$	(89	)

There was no revenue relating to discontinued operations for the years ended December 31, 2007, 2006 and 2005.

The following table sets forth the Company’s basic and diluted income (loss) per common share from discontinued operations excluding the gain on sale for the years ended December 31, 2007, 2006 and 2005:

For the years ended December 31,	2007			2006			2005
Basic income (loss) per common share from discontinued operations	$	(0.02	)	$	(0.03	)	$	(0.01	)
Diluted income (loss) per common share from discontinued operations	$	(0.02	)	$	(0.03	)	$	(0.01	)

The gain on disposition of discontinued operations recorded in 2007 of $20,000 compared to $56,000 in 2006 and $62,000 in 2005 relates to the gain on the sale of our Analytical Standards division as measured by royalty receipts in excess of guaranteed minimums.

As of December 31, 2007, liabilities related to the discontinued operations in the amount of $423,000 include severance costs and accruals for gross profit guarantees. These liabilities are reported as accrued disposition costs in the accompanying balance sheets.

The cash used in discontinued operations of $169,000 in 2007 relates to two payments made for the Gross Profit Guaranty, partially offset by the royalties received from GFS Chemicals, Inc. (“GFS”), a privately held company based in Columbus, Ohio, from sales of Analytical Standards products. The cash provided by discontinued operations of $24,000 and $125,000 in 2006 and 2005, respectively, relates to the royalties received from GFS from sales of Analytical Standards products, partially offset by severance payments made to former employees who were terminated as a result of the sale of the Analytical Standards division and a payment relating to the Gross Profit Guaranty.

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2007, 2006 AND 2005

Analytical Standards Division

On February 13, 2003, we completed the sale of our Analytical Standards division to GFS. In this transaction, we received $2.1 million on closing and are entitled to receive royalties on sales of Analytical Standards products for a period of five years following the sale at rates ranging from 5% to 15%. The net present value of the guaranteed minimum royalties is included in the gain on disposition of discontinued operations.

As a result of the sale of the Analytical Standards division, we recorded severance charges of $210,000 in the year ended December 31, 2003 as a partial offset to the gain on disposition of the Analytical Standards division. An increase to the estimated severance charges of $1,000 was recorded in 2007. Approximately $231,000 of these severance charges has been paid through December 31, 2007.

Cosmeceutical and Toiletry Business

On July 25, 2000, we completed the sale of certain technology rights for our topical pharmaceutical and cosmeceutical product lines and other assets (“cosmeceutical and toiletry business”) to RP Scherer Corporation, a subsidiary of Cardinal Health, Inc.

Under the terms of the agreement with RP Scherer, we guaranteed a minimum gross profit percentage on RP Scherer’s combined sales of products to Ortho Neutrogena and Dermik (“Gross Profit Guaranty”). The guaranty period commenced on July 1, 2000 and ends on the earlier of July 1, 2010 or the end of two consecutive guaranty periods where the combined gross profit on sales to Ortho and Dermik equals or exceeds the guaranteed gross profit (the “two period test”). The Gross Profit Guaranty expense totaled $944,000 for the first seven guaranty years and in those years profits did not meet the two period test. Effective March 2007, in conjunction with a sale of assets by RP Scherer’s successor company to an Amcol International subsidiary (“Amcol”), a new agreement was signed between us and Amcol to provide continuity of product supply to Ortho and Dermik. This new agreement potentially extends the gross profit guaranty period an additional three years to July 1, 2013 unless it is terminated earlier with the two period test. Therefore, we expect the annual Gross Profit Guaranty payment to range from $100,000 to $200,000 for the remainder of the guaranty period. As there is no minimum amount of Gross Profit Guaranty due, no accrual for the guaranty is estimable for future years. A liability of $420,000 related to the current amount due under gross profit guarantees is included in accrued disposition costs as of December 31, 2007.

NOTE 10 DEFINED CONTRIBUTION PLAN

We have a defined contribution plan (401k)covering substantially all of our employees. In the past three calendar years, we made matching cash contributions equal to 50% of each participant’s contribution during the plan year up to a maximum amount equal to the lesser of 3% of each participant’s annual compensation or $6,750, $6,600 and $6,300 for 2007, 2006 and 2005, respectively, and such amounts were recorded as expense in the corresponding years. We may also contribute additional discretionary amounts to the defined contribution plan as we may determine. For the years ended December 31, 2007, 2006 and 2005, we contributed to the plan approximately $84,000, $85,000 and $73,000, respectively. No discretionary contributions have been made to the plan since its inception.

NOTE 11 INCOME TAXES

There was no provision for income taxes in 2007 and 2005 because we have incurred operating losses. In 2006, we had a provision of $119,000 reflecting alternative minimum tax on the gain on the sale of our right to receive royalties on the sales of Retin A Micro and Carac (see Note 12 for details). Deferred income taxes reflect the net tax effects of net operating loss and tax credit carryovers and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of our deferred tax assets are as follows (in thousands):

December 31,	2007			2006
Deferred Tax Assets:

Valuation allowance		(33,680	)		(26,240	)
Net deferred tax assets	$	—		$	—

Realization of deferred tax assets is dependent upon future earnings, if any, the timing and amount of which are uncertain. Accordingly, the net deferred tax assets have been fully offset by a valuation allowance. The valuation allowance increased by $7.44 million, decreased by $1.9 million and increased by $600,000 during 2007, 2006 and 2005, respectively. In accordance with SFAS 123(R), we have excluded certain tax benefits resulting from employee stock option exercises from our deferred tax asset at December 31, 2007 and 2006. In the future, if and when such tax benefits are ultimately realized, the amount of the excess tax benefits will be credited to additional paid-in capital in our statements of stockholders’ equity.

As of December 31, 2007, we had federal and California net operating loss carryforwards of $81.5 million and $38.5 million, respectively, and federal and California research and development tax credit carryforwards of $1.9 million and 2.4 million, respectively. Approximately $2.9 million of federal and state net operating loss carryforwards represent stock option deductions arising from activity under our stock option plan, the benefits of which will increase additional paid-in capital, when realized.

The federal and state net operating losses and the federal research and development credit carryforwards expire at various dates beginning in the years 2008 through 2027, if not utilized. The Internal Revenue Code of 1986, as amended, contains provision that may limit the net operating loss and tax credit carry forwards available for use in any given period upon the occurrence of certain events, including a significant change in ownership interests. We recently conducted an analysis of our stock ownership to determine whether Section 382 would limit the use of these tax attributes. Based on that analysis, we believe our net operating losses and tax attributes are not subject to the limitation under this section of the Internal Revenue Code. However, utilization of our net operating loss and research and development credit carryforwards may still be subject to substantial annual limitations due to ownership change limitations provided by the Internal Revenue Code and similar state provisions for ownership changes after December 31, 2007. Such an annual limitation could result in the expiration of the net operating loss and research and development credit carryforwards available as of December 31, 2007 before utilization.

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2007, 2006 AND 2005

We adopted the provisions of FIN 48 as of January 1, 2007, which resulted in the reversal of certain fully reserved deferred tax assets totaling $1.02 million and the related valuation allowance. The following is a tabular reconciliation of the total amount of unrecognized tax benefits for the year ended December 31, 2007 (in thousands):

Unrecognized tax benefit at January 1, 2007	$	1,022
Gross increases – tax positions in current period		—
Gross decreases – tax positions in current period		—
Unrecognized tax benefit at December 31, 2007	$	1,022

The unrecognized tax benefit, if recognized in full, would reduce our income tax expense by $1.02 million and result in adjustments to other tax accounts, primarily deferred taxes. We do not currently anticipate any significant changes to the unrecognized tax benefits within 12 months of December 31, 2007. Our policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of tax expense. To date, we have not used the unrecognized tax benefits to reduce any of our past tax obligations. As a result, we had no accrual for the payment of interest and penalties related to the unrecognized tax benefits at January 1, 2007 nor was any amount of interest and penalties recognized during the year ended December 31, 2007. As of December 31, 2007, our tax returns were subject to future examination in the U.S. federal and state tax jurisdictions for the tax years 1993 through 2006, due to net operating losses and research credits that are being carried forward.

NOTE 12 SIGNIFICANT AGREEMENTS

Paul Royalty Fund

On January 18, 2006 we sold our rights to royalties on sales of Retin-A Micro and Carac effective October 1, 2005 to an affiliate of the Paul Royalty Fund for up to $30 million. Proceeds of $25 million were received upon the closing of the transaction and used primarily to fund pivotal clinical development of APF530, our drug candidate for the prevention of both acute and delayed chemotherapy-induced nausea and vomiting. The remaining $5 million was to be received upon the achievement of certain milestones over the successive four years. Upon attainment of one milestone in 2007, an additional $2.5 million was received. The remaining $2.5 million will be paid based on the satisfaction of certain other predetermined milestones over the next two years.

RHEI Pharmaceuticals, Inc.

On October 1, 2006, we entered into an agreement with RHEI in which we granted RHEI exclusive license to develop and market APF530 in Greater China. We received a license fee on the signing of the contract, which has been recorded as deferred revenue on the Balance Sheet, and will receive additional milestone payments upon the achievement of certain regulatory approvals. Furthermore, we will receive royalties on future sales of APF530 in Greater China.

Animal Health Company

On January 22, 2007 we entered a collaborative research and development agreement with a major animal health company to develop a product providing the slow release of an undisclosed opiate for use in the control of pain for dogs and cats. Under the terms of the agreement, we will be reimbursed for certain costs incurred by us and will receive milestone payments upon the achievement of certain development milestones. The animal health company will retain rights for use of the product in its field, paying us a royalty, while we retain rights to the same technology for potential use for humans.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Based on an evaluation as of the end of the period covered by this report, our chief executive officer and chief financial officer has concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act were effective as of the end of the period covered by this report to ensure that information that we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms.

Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives, and our chief executive officer and chief financial officer has concluded that these controls and procedures are effective at the “reasonable assurance” level. We believe that a control system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the control system are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

There are inherent limitations in the effectiveness of any system of internal control, including the possibility of human error and the circumvention or overriding of controls. Accordingly, even effective internal controls can provide only reasonable assurances with respect to financial statement preparation. Further, because of changes in conditions, the effectiveness of internal control may vary over time.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2007. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations (COSO) of the Treadway Commission in Internal Control—Integrated Framework. Based on our assessment using the COSO criteria, management concluded that, as of December 31, 2007, our internal control over financial reporting is effective.

This annual report does not include an attestation report of our independent registered public accounting firm regarding internal control over financial reporting. Our internal control over financial reporting was not subject to attestation by our independent registered public accounting firm pursuant to temporary rules of the SEC that permit us to provide only management’s report in this annual report.
