You should carefully consider the risks described below and the other information in this prospectus before purchasing our common stock. We have experienced a history of losses and we expect to incur future losses. - ----------------------------------------------------------------------------- We have recorded minimal revenue to date and we have incurred a cumulative operating loss of approximately $54.0 million through December 31, 2003. Losses for the years ended 2003, 2002 and 2001 were $6,735,000, $9,384,000 and $6,027,000, respectively. Our losses have resulted principally from costs incurred in research and development activities related to our efforts to develop clinical candidates and from the associated administrative costs. We expect to incur significant additional operating losses over the next several years. We also expect cumulative losses to increase due to expanded research and development efforts and preclinical and clinical trials. Our net cash burn rate for the twelve months of 2003 was $601,000 per month. We project our net cash burn rate for the next twelve months to be approximately $400,000 per month. Capital expenditures are forecasted to be minor for the next twelve months since most of our new equipmentwebsite address is leased and the lease expense is included in the calculation of the net cash burn rate.www.plasmatechbio.com.

Marketed Product

MuGard® is our marketed product for the management of oral mucositis, a frequent side-effect of cancer therapy for which there is no other established treatment. The market for mucositis treatment is estimated to be in excess of $1.0 billion worldwide. MuGard, a proprietary nanopolymer formulation, has received marketing clearance in the U.S. from the FDA. We launched MuGard in the U.S. in 2010.

Recent MuGard Developments

On August 5, 2010, we entered into an exclusive license with RHEI Pharmaceuticals, N.V. (“RHEI”) related to the commercialization of MuGard in China and other Southeast Asian countries. Our China partners have received an acceptance letter from the State Food and Drug Administration of the People’s Republic of China, which provides marketing approval in China. MuGard has been manufactured in the U.S. and shipped to China for sale. RHEI has rights to sub-license MuGard sales in some Southeast Asia countries.

On June 6, 2013 we entered into an exclusive license agreement with AMAG Pharmaceuticals, Inc. (“AMAG”), related to the commercialization of MuGard in the U.S. and its territories. Under the terms of the licensing agreement we received an upfront licensing fee of $3.3 million and will receive a tiered, double-digit royalty on net sales of MuGard in the licensed territory. We receive quarterly royalty payments from AMAG.

On March 11, 2014, we announced we had entered into an exclusive license agreement with Hanmi Pharmaceutical Co. Ltd. (“Hanmi”) related to MuGard commercialization in South Korea. Under the terms of the agreement, we received an upfront licensing fee and will receive double digit royalties on sales of MuGard in the licensed territory.

On July 8, 2014, we announced we received notification from the Hong Kong Patent Office that a patent for MuGard has been granted.

On August 7, 2014, we entered into an exclusive license agreement with Norgine B.V. (“Norgine”), a leading independent European specialty pharmaceutical company, for the commercialization of MuGard in Europe. Under the terms of the license agreement, we could receive up to $10 million in milestone payments and licensing fees from corporate alliances and mergers have also provided funding for our operations. Our ability to achieve significant revenue or profitability depends upon our ability to successfully completean escalating double digit royalty on the developmentnet sales of drug candidates, tothe oral mucositis product, MuGard, in the licensed territories. Norgine will develop, and obtain patent protection and regulatory approvals for our drug candidates and to manufacture, and commercialize MuGard in the resulting drugs. We have notEuropean Union, Switzerland, Norway, Iceland and Lichtenstein. Norgine anticipates launching MuGard in 2015.

On September 12, 2014, we announced we had received significant royalties for sales of amlexanox or Zindaclin(R) products 3 to date and we may not generate significant revenues or profitsnotification from the saleEuropean Patent Office that an additional European patent for MuGard had been granted. The patent (EP1997478) protects a wide range of these products inliquid formulations for the future. Furthermore,prevention and treatment of mucosal diseases and disorders.

On October 27, 2014, we may not be able to ever successfully identify, develop, commercialize, patent, manufacture, obtain required regulatory approvals and market any additional products. Moreover, even if we do identify, develop, commercialize, patent, manufacture, and obtain required regulatory approvals to market additional products, we may not generate revenues or royalties from commercial sales of these productsentered into an exclusive license agreement with Norgine for a significant number of years, if at all. Therefore, our proposed operations are subject to all the risks inherent in the establishment of a new business enterprise. In the next few years, our revenues may be limited to minimal royalties, any amounts that we receive under strategic partnerships and research or drug development collaborations that we may establish and, as a result, we may be unable to achieve or maintain profitability in the future or to achieve significant revenues in order to fund our operations. We may not successfully commercialize our drug candidates. - ---------------------------------------------------------- Our drug candidates are subject to the risks of failure inherent in the development of pharmaceutical products based on new technologies and our failure to develop safe, commercially viable drugs would severely limit our ability to become profitable or to achieve significant revenues. We may be unable to successfully commercialize our drug candidates because: * some or all of our drug candidates may be found to be unsafe or ineffective or otherwise fail to meet applicable regulatory standards or receive necessary regulatory clearances; * our drug candidates, if safe and effective, may be too difficult to develop into commercially viable drugs; * it may be difficult to manufacture or market our drug candidates on a large scale; * proprietary rights of third parties may preclude us from marketing our drug candidates; and * third parties may market superior or equivalent drugs. The success of our research and development activities, upon which we primarily focus, is uncertain. - --------------------------------------------------------------------- Our primary focus is on our research and development activities and the commercialization of compounds covered by proprietary biopharmaceutical patentsMuGard in Australia and patent applications. ResearchNew Zealand. The terms of the agreement are congruent to our recent license with Norgine for MuGard in Europe. Norgine intends to develop, manufacture and development activities, by their nature, preclude definitive statements as to the time required and costs involved in reaching certain objectives. Actual research and development costs, therefore, could exceed budgeted amounts and estimated time frames may require extension. Cost overruns, unanticipated regulatory delays or demands, unexpected adverse side effects or insufficient therapeutic efficacy will prevent or substantially slow our research and development effort and our business could ultimately suffer. We anticipate that we will remain principally engaged in research and development activities for an indeterminate, but substantial, period of time. We may be unable to obtain necessary additional capital to fund operationscommercialize MuGard in the future. - -------------------------------------------------------------------------- new territories.

On March 31, 2015, we announced that Hanmi has received marketing approval in Korea from the country’s Ministry of Food and Drug Safety and the Korea Testing & Research Institute for MuGard. Hanmi intends to market MuGard in Korea under the trade name Mucogard.

We require substantial capitalare actively seeking partners to license MuGard in other territories.

Product Candidates

ProctiGardTM received 510(K) marketing clearance from the FDA on July 22, 2014 for the treatment of symptomatic management of rectal mucositis. ProctiGard is our product for the treatment of radiation proctitis, a frequent side effect of radiation treatment to the pelvic region. Radiation proctitis, or RP, is the inflammation and damage to the lower portion of the colon after exposure to x-rays or ionizing radiation as part of radiation therapy. RP is most common after treatments for cancer, such as cervical, colon and prostate cancer. RP can be acute, occurring within weeks of initiation of therapy, or can occur months or years after treatment. We intend to commercialize ProctiGard in a manner similar to the commercialization of MuGard, which may include confirmatory clinical trials, with the objective of commercialization in collaboration with marketing partners globally.
We are also developing additional products using our development programs and operating expenses, to pursue regulatory clearances and to prosecute and defendproprietary mucoadhesive hydrogel technology as a mucoprotectant and/or delivery vehicle, as well as our intellectual property rights. Although we believe that our existing capital resources, interest income, product sales, royalties and revenue from possible licensing agreements and collaborative agreements will be sufficient to fund our currently expected operating expenses and capital requirements through 2005, we may need to raise substantial additional capital during that period to support our ongoing operations because our actual cash requirements may vary materially from those now planned and will depend upon numerous factors, including : * the sales levelsvitamin B-12 mediated delivery technology.

Drug Development Strategy

We have a rich potential pipeline of our currently marketed products; * the results of our research and development programs; * the timing and results of preclinical and clinical trials; * our ability to maintain existing and establish new collaborative agreements with other companies to provide funding to us; * technological advances; and 4 * activities of competitors and other factors. If we do raise additional funds by issuing equity securities, further dilution to existing stockholders would result and future investors may be granted rights superior to those of existing stockholders. If adequate funds are not available to us through additional equity offerings, we may be required to delay, reduce the scope of or eliminate one or more of our research and development programs or to obtain funds by entering into arrangements with collaborative partners or others that require us to issue additional equity securities or to relinquish rights to certain technologies or drug candidates that we would not otherwise issue or relinquish in order to continue independent operations. We may be unable to successfully develop, market, or commercialize our products or our product candidates without establishing new relationships and maintaining current relationships. - ------------------------------------------------------------------------- Our strategy for the research, development and commercialization of our potential pharmaceutical products may require us to enter into various arrangements with corporate and academic collaborators, licensors, licensees and others, in addition to our existing relationships with other parties. Specifically, if we successfully develop any commercially marketable pharmaceutical products, we may seek to enter joint venture, sublicense or other marketing arrangements with parties that have an established marketing capability or we may choose to pursue the commercialization of such products on our own. We may, however, be unable to establish such additional collaborative arrangements, license agreements, or marketing agreements as we may deem necessary to develop, commercialize and market our potential pharmaceutical products on acceptable terms. Furthermore, if we maintain and establish arrangements or relationships with third parties, our business may depend upon the successful performance by these third parties of their responsibilities under those arrangements and relationships. For our commercialized products we currently rely upon the following relationships in the following marketing territories: * amlexanox 5% paste o Strakan Ltd. - United Kingdom and Ireland manufacturing and marketing rights o Zambon Group - France, Germany, Holland, Belgium, Luxembourg, Switzerland, Brazil, Colombia and Italy manufacturing and marketing rights o Laboratories Dr. Esteve SA - Spain, Portugal and Greece manufacturing and marketing rights o Meda, AB for Scandinavia, the Baltic states and Iceland marketing rights o Mipharm SpA for Italy manufacturing and marketing rights o Paladin Labs, Inc. for Canada manufacturing and marketing rights * Zindaclin(R) and Residerm(R) o Strakan Ltd. - worldwide manufacturing and marketing rights o Fujisawa GmbH - sublicensed continental Europe marketing rights o Taro - sublicensed Israel marketing rights o Various companies for other smaller countries - sublicensed marketing rights Our ability to successfully commercialize, and market our products and product candidates could be limited if a number of these existing relationships were terminated. Furthermore, our strategyranging from preclinical development candidates to one approved product. To maximize return on this portfolio, we plan to develop in-house or with respect to our polymer platinate program is to entercollaborators the following products and technologies: MuGard, ProctiGard and mucoadhesive hydrogel technology.

SDF Licensed Technology

On September 22, 2014, we entered into aan exclusive, worldwide licensing agreement with a pharmaceutical company pursuant to which the further costs of developing a product would be shared with our licensing partner. Although we have had discussions with potential licensing partners with respect to our polymer platinate program, to date we have not entered into any licensing arrangement. We may be unable to execute our licensing strategy for polymer platinate. We may be unable to successfully manufacture our products and our product candidates in clinical quantities or for commercial purposes without the assistance of contract manufacturers, which may be difficult for usLicensor to obtain rights to utilize and maintain. - ------------------------------------------------------------------------- 5 We have limited experience in the manufacture ofto sub-license to other pharmaceutical products in clinical quantities or for commercial purposes and we may not be able to manufacture any new pharmaceutical products that we may develop. As a result, we have established, and in the future intend to establish arrangements with contract manufacturers to supply sufficient quantities of products to conduct clinical trials andfirms its patented methods for the manufacture, packaging, labelingextraction of therapeutic biologics from human plasma. Plasma biologics are bio-pharmaceutical proteins extracted, purified, and distributionformulated from human blood plasma by the use of finished pharmaceutical products if any of our potential productsbiotechnological processing techniques including precipitation, diafiltration, affinity chromatography, and ion-exchange chromatography. Because plasma biologics are approved for commercialization. If webiosimilar, they are unableless likely than recombinant or transgenic proteins to contract for a sufficient supply of our potential pharmaceutical products on acceptable terms, our preclinical and human clinical testing schedule may be delayed, resulting in the delay of our submission of products for regulatory approval and initiation of new development programs, which could cause our business to suffer. Delays or difficulties in establishing relationships with manufacturers to produce, package, label and distribute our finished pharmaceuticaltoxic or other medical products, if any, market introduction and subsequent salesadverse reactions, or cause adverse immunological responses such as the stimulation of such products could cause our business to suffer. Moreover, contract manufacturers that we may use must adhere to current Good Manufacturing Practices, as required by the FDA. In this regard, the FDA will not issue a pre-market approval or product and establishment licenses, where applicable, to a manufacturing facility for the products until after the manufacturing facility passes a pre- approval plant inspection. If we are unable to obtain or retain third party manufacturing on commercially acceptable terms, we may not be able to commercialize our products as planned. Our potential dependence upon third parties for the manufacture of our products may adversely affect our profit margins and our ability to develop and deliver such products on a timely and competitive basis. Our amlexanox 5% paste is marketedinhibitors in the US as Aphthasol(R). Block Drug Company had manufactured the 5% amlexanox paste since the product was approved by the FDA in 1996 in a Puerto Rico facility certified by the FDA for Good Manufacturing Practices. At such time when we acquired the US rights to Aphthasol(R) we entered into a Supply Agreement whereby Block Drug Company was to produce Aphthasol(R) for us for a defined period of time at its Puerto Rico facility. We were subsequently advised by Block Drug Company that it was unable to comply withrecipients.

Under the terms of the Supply Agreement and that it would not be able to produce Aphthasol(R) for us. Due to Block Drug Company's production failure,licensing agreement, as amended on January 23, 2015, we had sufficient product to supply wholesalers only through June 2003. We do not anticipate further salespaid a license fee of the product until the second quarter$1 million in cash, will pay $4 million in cash or 1,096,151 shares of 2004. We acquired the rights to amlexanox 5% paste from Block Drug Company on July 22, 2002. We have selected Contract Pharmaceuticals Ltd. Canada as our new manufacturercommon stock in 2017, a regulatory approval milestone payment of amlexanox 5% paste and it has produced initial qualifying batches513,375 shares of the product. Full scale production commenced inour common stock upon the first quarter of 2004. Amlexanox 5% paste was approved by regulatory authorities for sale in the UK and is currently in the approval process in the remaining EU countries. We licensed manufacturing rights to Strakan, Zambon, Esteve and Mipharm for specific countries in Europe. Contract Pharmaceuticals Ltd. Canada has also been selected as our European supplier of amlexanox 5% paste and a UK filing has been made to approve this facility for European supply. We licensed our patents for worldwide manufacturing and marketing for Zindaclin(R) and the ResiDerm(R) technology to Strakan Ltd. for the period of the patents. We receive a royalty on the sales of the product. Strakan has a contract manufacturer for Zindaclin(R) in a European Union approved facility. Zindaclin(R) was approved in the UK and seven additional European Union countries and is currently under review for approval in the remaining EU countries. OraDisc(TM) was manufactured by a third party for our Phase III clinical trials. Enough product was manufactured to cover the needs of the clinical trials and testing. We finalized with a third party a contract for manufacturing our product if our product gains regulatory approval. AP5280 and AP5346 are manufactured by a third parties for our Phase I/II clinical trials. Manufacturing is ongoing for the current clinical trials. Certain manufacturing steps are conducted by the Company to enable significant cost savings to be realized. Our mucoadhesive technology is manufactured by a third party for our clinical trials. 6 We are subject to extensive governmental regulation which increases our cost of doing business and may affect our ability to commercialize any new products that we may develop. - ----------------------------------------------------------------------- The FDA and comparable agencies in foreign countries impose substantial requirements upon the introduction of pharmaceutical products through lengthy and detailed laboratory, preclinical and clinical testing procedures and other costly and time-consuming procedures to establish their safety and efficacy. All of our drug candidates require governmental approvals for commercialization. Preclinical and clinical trials and manufacturing of our drug candidates will be subject to the rigorous testing and approval processes of the FDA and corresponding foreign regulatory authorities. Satisfaction of these requirements typically takes a significant number of years and can vary substantially based upon the type, complexity and novelty of the product. The status of our principal products is as follows: * 5% amlexanox paste is an approved product for sale in the US (Aphthasol(R)); approved in the UK and Canada but not yet sold; and, in the approval process in the EU. * Zindaclin(R) is an approved product for sale in the UK and seven additional European Union countries; in the approval process in the remaining EU countries; and waiting for finalized plans and approval to start a Phase III trial in the US. * OraDisc(TM) has completed a Phase III clinical trial in the US and we filed an NDA. * AP5280 has completed Phase I of its Phase I/II trial in Europe and we are analyzing the results to start the Phase II part of the trial. * AP5346 is currently in a Phase I trial in Europe. * Mucoadhesive liquid technology is planned to start a Phase III trial in the US in the second quarter of 2004. * Vitamin mediated delivery technology is currently in the pre-clinical phase. * We also have other products in the preclinical phase. Due to the time consuming and uncertain nature of the drug candidate development process and the governmental approval process described above, we cannot assure you when we, independently or with our collaborative partners, might submit a New Drug Application, or "NDA", for FDA or other regulatory review. Government regulation also affects the manufacturing and marketing of pharmaceutical products. Government regulations may delay marketing of our potential drugs for a considerable or indefinite period of time, impose costly procedural requirements upon our activities and furnish a competitive advantage to larger companies or companies more experienced in regulatory affairs. Delays in obtaining governmental regulatory approval could adversely affect our marketing as well as our ability to generate significant revenues from commercial sales. Our drug candidates may not receive FDA or other regulatory approvals on a timely basis or at all. Moreover, if regulatory approval of a drug candidate is granted, such approval may impose limitations on the indicated use for which such drug may be marketed. Even if we obtain initial regulatory approvals for our drug candidates, Access, and our drugs and our manufacturing facilities would be subject to continual review and periodic inspection, and later discovery of previously unknown problems with a drug, manufacturer or facility may result in restrictions on the marketing or manufacture of such drug, including withdrawal of the drugderived from the market. The FDALicensor’s proprietary SDF process, and a tiered royalty on annual net sales of plasma fractions produced with Licensor’s proprietary SDF process.

Licensor was founded to develop superior high-yield technology to extract a wide range of therapeutically useful proteins from human blood plasma. We believe that Licensor’s proprietary SDF process is expected to significantly enhance yields of key value blood proteins, including alpha-1 protease inhibitor (“A1PI”), expanding market opportunities, while greatly enhancing margins. We obtained rights to utilize and sub-license to other regulatory authorities stringently apply regulatory standards and failure to comply with regulatory standards can,pharmaceutical firms the recently patented improved methods for the extraction of therapeutic biologics from human plasma. We believe that Licensor’s lead product, A1PI offers a low-risk, high revenue, short time-to-market respiratory product for treatment of inherited COPD (pulmonary emphysema), among other things, result in fines, denial or withdrawal of regulatory approvals, product recalls or seizures, operating restrictions and criminal prosecution. The uncertainty associated with preclinical and clinical testing may affect ourgenetic A1PI deficiencies. Additionally, the ability to successfully commercialize new products. - --------------------------------------------------------------------------- Before we can obtain regulatory approvals for the commercial sale of any of our potential drugs, the drug candidates will be subject to extensive preclinicalextract several additional therapeutically useful and clinical trials to demonstrate their safety and efficacy in humans. Preclinical or clinical trials of any of our future drug candidates may not demonstrate the safety and efficacy of such drug candidates at all or to the extent necessary to obtain regulatory 7 approvals. In this regard, for example, adverse side effects can occur during the clinical testing of a new drug on humans which may delay ultimate FDA approval or even lead us to terminate our efforts to develop the drug for commercial use. Companies in the biotechnology industry have suffered significant setbacks in advanced clinical trials, even after demonstrating promising results in earlier trials. In particular, OraDisc(TM) and AP5280 have taken longer to progress through clinical trials than originally planned. This extra time has not been related to concerns of the formulations but ratherimportant proteins, due to the lengthy regulatory process. The failureprocess being less destructive than historical fractionation processes, may enable us to adequately demonstrate the safetyseek new therapeutic applications and efficacy of a drug candidate under development could delay or prevent regulatory approval of the drug candidate. A delay or failure to receive regulatory approval for any of our drug candidates could prevent us from successfully commercializing such candidates and we could incur substantial additional expensesaddress high-value-added orphan indications.

RISK FACTORS

An investment in our attemptssecurities involves risks. We urge you to further developconsider carefully the risks described in the documents incorporated by reference in this prospectus before making an investment decision, including those risks identified under “Item IA. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2014, filed with the Securities and Exchange Commission on March 31, 2015, which report is incorporated by reference in this prospectus, as such candidates and obtain future regulatory approval. We may incur substantial product liability expenses due to the use or misuse of our products for which weinformation may be unableamended, supplemented or superseded from time to obtain insurance coverage. - ---------------------------------------------------------------------- Our business exposes us to potential liability riskstime by other reports that we subsequently file with the Securities and Exchange Commission.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the other documents we have filed with the SEC that are inherent in the testing, manufacturing and marketing of pharmaceutical products. These risks will expand with respect to our drug candidates, if any, that receive regulatory approval for commercial sale and we may face substantial liability for damages in the event of adverse side effects or product defects identified with any of our products that are used in clinical tests or marketed to the public. We generally procure product liability insurance for drug candidates that are undergoing human clinical trials. Product liability insurance for the biotechnology industry is generally expensive, if available at all, and as a result, we may be unable to obtain insurance coverage at acceptable costs or in a sufficient amount in the future, if at all. We may be unable to satisfy any claims for which we may be held liable as a result of the use or misuse of products which we have developed, manufactured or sold and any such product liability claim could adversely affect our business, operating results or financial condition. We may incur significant liabilities if we fail to comply with stringent environmental regulations or if we did not comply with these regulations in the past. - ------------------------------------------------------------------------ Our research and development processes involve the controlled use of hazardous materials. We are subject to a variety of federal, state and local governmental laws and regulations related to the use, manufacture, storage, handling and disposal of such material and certain waste products. Although we believe that our activities and our safety procedures for storing, using, handling and disposing of such materials comply with the standards prescribedincorporated herein by such laws and regulations, the risk of accidental contamination or injury from these materials cannot be completely eliminated. In the event of such accident, we could be held liable for any damages that result and any such liability could exceed our resources. Intense competition may limit our ability to successfully develop and market commercial products. - ---------------------------------------------------------------------- The biotechnology and pharmaceutical industries are intensely competitive and subject to rapid and significant technological change. Our competitors in the United States and elsewhere are numerous and include, among others, major multinational pharmaceutical and chemical companies, specialized biotechnology firms and universities and other research institutions. The following products may compete with polymer platinum (AP5280) and DACH platinum (AP5346): * Cisplatin, marketed by Bristol-Myers-Squibb, the originator of the drug, and several generic manufacturers; * Carboplatin, marketed exclusively by Bristol-Myers-Squibb; and * Oxaliplatin, marketed exclusively by Sanofi-Synthelabo. The following companies are working on therapies and formulations that may be competitive with our polymer platinum (AP5280) and DACH platinum (AP5346): 8 * Antigenics is developing liposomal formulations; and * Cell Therapeutics, Daiichi, Enzon and Inhale are developing alternate drugs in combination with polymers. The following products may compete with our Residerm(R) products: * Benzamycin, marketed by a subsidiary of Aventis; * Cleocin-T and a generic topical clindamycin, marketed by Pharmacia; * Benzac, marketed by a subsidiary of L'Oreal; and * Triaz, marketed by Medicis Pharmaceutical Corp. Technology and prescription steroids such as Kenalog in OraBase, developed by Bristol-Myers Squibb, may compete with our commercialized Aphthasol(R) product. OTC products including Orajel - Del Laboratories and Anbesol - Wyeth Consumer Healthcare also compete in the aphthous ulcer market. Companies working on therapies and formulations that may be competitive with our vitamin mediated drug delivery system are Bristol-Myers-Squibb, Centocor (acquired by Johnson & Johnson), GlaxoSmithKline, Imclone and Xoma which are developing targeted monoclonal antibody therapy. RxKinetics, Human Genome Sciences, Endo Pharmaceuticals and Amgen are developing products to treat mucositis that may compete with the mucoadhesive liquid technology. Emisphere Technologies, Inc., Biovail Corporation, CIMA Labs, Inc., Depomed Inc. and Flamel Technologies are developing products which compete with our oral drug delivery system. Many of these competitors have and employ greater financial and other resources, including larger research and development staffs and more effective marketing and manufacturing organizations, than us or our collaborative partners. As a result, our competitors may successfully develop technologies and drugs that are more effective or less costly than any that we are developing or which would render our technology and future products obsolete and noncompetitive. In addition, some of our competitors have greater experience than we do in conducting preclinical and clinical trials and obtaining FDA and other regulatory approvals. Accordingly, our competitors may succeed in obtaining FDA or other regulatory approvals for drug candidates more rapidly than we do. Companies that complete clinical trials, obtain required regulatory agency approvals and commence commercial sale of their drugs before their competitors may achieve a significant competitive advantage. Drugs resulting from our research and development efforts or from our joint efforts with collaborative partners therefore may not be commercially competitive with our competitors' existing products or products under development. Our ability to successfully develop and commercialize our drug candidates will substantially depend upon the availability of reimbursement funds for the costs of the resulting drugs and related treatments. - -------------------------------------------------------------------------- The successful commercialization of, and the interest of potential collaborative partners to invest in, the development of our drug candidates will depend substantially upon reimbursement of the costs of the resulting drugs and related treatments at acceptable levels from government authorities, private health insurers and other organizations, including health maintenance organizations, or HMOs. To date, the costs of our marketed products Aphthasol(R) and Zindaclin(R) generally have been reimbursed at acceptable levels, however, the amount of such reimbursement in the United States or elsewhere may be decreased in the future or may be unavailable for any drugs that we may develop in the future. Limited reimbursement for the cost of any drugs that we develop may reduce the demand for, or price of such drugs, which would hamper our ability to obtain collaborative partners to commercialize our drugs, or to obtain a sufficient financial return on our own manufacture and commercialization of any future drugs. 9 The market may not accept any pharmaceutical products that we successfully develop. - ------------------------------------------------------------- The drugs that we are attempting to develop may compete with a number of well-established drugs manufactured and marketed by major pharmaceutical companies. The degree of market acceptance of any drugs developed by us will depend on a number of factors, including the establishment and demonstration of the clinical efficacy and safety of our drug candidates, the potential advantage of our drug candidates over existing therapies and the reimbursement policies of government and third- party payers. Physicians, patients or the medical community in general may not accept or use any drugs that we may develop independently or with our collaborative partners and if they do not, our business could suffer. In 1996, the 5% amlexanox paste product was approved for sale in the United States. To date, the product is not widely accepted in the marketplace and its sales have not been significant. On July 22, 2002, we acquired the rights to it from Block Drug Company and we intend to re- launch it in the second quarter of 2004. The product has been approved in the UK and Canada but has not been launched in any markets other than the United States. Trends toward managed health care and downward price pressures on medical products and services may limit our ability to profitably sell any drugs that we may develop. - -------------------------------------------------------------------------- Lower prices for pharmaceutical products may result from: * third-party payers' increasing challenges to the prices charged for medical products and services; * the trend toward managed health care in the United States and the concurrent growth of HMOs and similar organizations that can control or significantly influence the purchase of healthcare services and products; and * legislative proposals to reform healthcare or reduce government insurance programs. The cost containment measures that healthcare providers are instituting, including practice protocols and guidelines and clinical pathways, and the effect of any health care reform, could limit our ability to profitably sell any drugs that we may successfully develop. Moreover, any future legislation or regulation, if any, relating to the healthcare industry or third-party coverage and reimbursement, may cause our business to suffer. We may not be successful in protecting our intellectual property and proprietary rights. - -------------------------------------------------------------------- Our success depends, in part, on our ability to obtain U.S. and foreign patent protection for our drug candidates and processes, preserve our trade secrets and operate our business without infringing the proprietary rights of third parties. Legal standards relating to the validity of patents covering pharmaceutical and biotechnological inventions and the scope of claims made under such patents are still developing and there is no consistent policy regarding the breadth of claims allowed in biotechnology patents. The patent position of a biotechnology firm is highly uncertain and involves complex legal and factual questions. We cannot assure you that any existing or future patents issued to, or licensed by, us will not subsequently be challenged, infringed upon, invalidated or circumvented by others. As a result, although we, together with our subsidiaries, are either the owner or licensee of technology to 26 U.S. patents and to 16 U.S. patent applications now pending, and 7 European patents and 17 European patent applications, we cannot assure you that any additional patents will issue from any of the patent applications owned by, or licensed to, us. Furthermore, any rights that we may have under issued patents may not provide us with significant protection against competitive products or otherwise be commercially viable. Our patents for the following technologies expire in the years and during the date ranges indicated below: 10 * 5% amlexanox paste in 2011 * Zindaclin(R) and Residerm(R) between 2007 and 2011 * OraDisc(TM) in 2020 * AP5280 in 2021 * AP5346 in 2021 * Mucoadhesive technology, patents are pending * Vitamin mediated technology between 2003 and 2019 In addition, patents may have been granted to third parties or may be granted covering products or processes that are necessary or useful to the development of our drug candidates. If our drug candidates or processes are found to infringe upon the patents or otherwise impermissibly utilize the intellectual property of others, our development, manufacture and sale of such drug candidates could be severely restricted or prohibited. In such event, we may be required to obtain licenses from third parties to utilize the patents or proprietary rights of others. We cannot assure you that we will be able to obtain such licenses on acceptable terms, if at all. If we become involved in litigation regarding our intellectual property rights or the intellectual property rights of others, the potential cost of such litigation, regardless of the strength of our legal position, and the potential damages that we could be required to pay could be substantial. Our business could suffer if we lose the services of, or fail to attract, key personnel. - ----------------------------------------------------------------------------- We are highly dependent upon the efforts of our senior management and scientific team, including our President and Chief Executive Officer, Kerry Gray. The loss of the services of one or more of these individuals could delay or prevent the achievement of our research, development, marketing, or product commercialization objectives. While we have employment agreements with Mr. Gray and David Nowotnik our Senior Vice President Research and Development, their employment may be terminated by them or us at any time. Mr. Gray's and Dr. Nowotnik's agreements expire within one year and are extendable each year on the anniversary date. We do not have employment contracts with our other key personnel. We do not maintain any "key-man" insurance policies on any of our key employees and we do not intend to obtain such insurance. In addition, due to the specialized scientific nature of our business, we are highly dependent upon our ability to attract and retain qualified scientific and technical personnel. In view of the stage of our development and our research and development programs, we have restricted our hiring to research scientists and a small administrative staff and we have made no investment in manufacturing, production, marketing, product sales or regulatory compliance resources. If we develop pharmaceutical products that we will commercialize ourselves, however, we will need to hire additional personnel skilled in the clinical testing and regulatory compliance process and in marketing and product sales. There is intense competition among major pharmaceutical and chemical companies, specialized biotechnology firms and universities and other research institutions for qualified personnel in the areas of our activities, however, and we may be unsuccessful in attracting and retaining these personnel. Ownership of our shares is concentrated, to some extent, in the hands of a few investors which could limit the ability of our other stockholders to influence the direction of the company. - -------------------------------------------------------------------------- Heartland Advisors, Inc. and Larry N. Feinberg (Oracle Partners LP, Oracle Institutional Partners LP and Oracle Investment Management Inc.) each currently beneficially own approximately 12.1% of our common stock as of March 22, 2004. Accordingly, they collectively may have the ability to significantly influence or determine the election of all of our directors or the outcome of most corporate actions requiring stockholder approval. They may exercise this ability in a manner that advances their best interests and not necessarily those of our other stockholders. Provisions of our charter documents could discourage an acquisition of our company that would benefit our stockholders and may have the effect of entrenching, and making it difficult to remove, management. - ----------------------------------------------------------------------- Provisions of our Certificate of Incorporation, By-laws and Stockholders Rights Plan may make it more difficult for a third party to acquire control of our company, even if a change in control would benefit 11 our stockholders. In particular, shares of our preferred stock may be issued in the future without further stockholder approval and upon such terms and conditions, and having such rights, privileges and preferences, as our Board of Directors may determine, including, for example, rights to convert into our common stock. The rights of the holders of our common stock will be subject to, and may be adversely affected by, the rights of the holders of any of our preferred stock that may be issued in the future. The issuance of our preferred stock, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire control of us. This could limit the price that certain investors might be willing to pay in the future for shares of our common stock and discourage these investors from acquiring a majority of our common stock. Further, the existence of these corporate governance provisions could have the effect of entrenching management and making it more difficult to change our management. Substantial sales of our common stock could lower our stock price. - ------------------------------------------------------------------ The market price for our common stock could drop as a result of sales of a large number of our presently outstanding shares. Of the 15,314,816 shares of our common stock that are outstanding as of March 22, 2004, 13,525,445 are unrestricted and freely tradable or tradable pursuant to a resale registration statement or under Rule 144 of the Securities Act. An additional 1,789,371 shares of common stock that are outstanding as of March 22, 2004 are being registered hereunder and, upon effectiveness of the registration statement of which this prospectus forms a part, will be eligible for public resale. We are not currently in compliance with AMEX continued listing requirements and may not be able to maintain our AMEX listing. - -------------------------------------------------------------- Our common stock is presently listed on the American Stock Exchange under the symbol "AKC". All companies listed on AMEX are required to comply with certain continued listing standards, including maintaining stockholders' equity at required levels. We are not in compliance with this stockholders' equity standard as of December 31, 2003. However, we have until November 2004 to become compliant with such equity standard. If we are unable to remedy any listing standard noncompliance with AMEX under its regulations, or otherwise regain compliance, we cannot assure you that our common stock will continue to remain eligible for listing on AMEX. In the event that our common stock is delisted from AMEX its market value and liquidity could be materially adversely affected.

(2) That, for the purpose of determining any liability under the Securities Act, of 1933, each such post-effective amendment shall be deemed to be a new Registration Statementregistration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(5) That, for the purpose of determining liability under the Securities Act to any purchaser:

(i) each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus.

(6) That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(h) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrantregistrant pursuant to the foregoing provisions described inunder Item 15 above, or otherwise, the Registrantregistrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrantregistrant of expenses incurred or paid by a director, officer or controlling person of the Registrantregistrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrantregistrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
