PROSPECTUS SUMMARY

        This is a summary of our business and this offering. For a more complete understanding of our business and this offering, you should read this entire prospectus supplement, the accompanying prospectus and the documents incorporated by reference.

Overview

        We are a biopharmaceutical company focused on discovering and developing targeted, receptor-specific small molecule and peptide therapeutics. Our proprietary drug development pipeline is based primarily on melanocortin (“MC”)-based therapeutics, and we believe we are a leader in this fast growing area of pharmaceutical research and development. Therapeutics affecting the activity of the MC family of receptors may have the potential to treat a variety of conditions and diseases, including sexual dysfunction, obesity and related disorders, cachexia (extreme wasting, generally secondary to a chronic disease), skin pigmentation and inflammation.

        In August 2004, we entered into a collaborative development and marketing agreement with King Pharmaceuticals, Inc. (“King”), a specialty pharmaceutical company, to jointly develop and commercialize bremelanotide (formerly known as PT-141), our nasally administered MC-based peptide presently in Phase 2 clinical development for two distinct indications, male erectile dysfunction (“ED”) and female sexual dysfunction (“FSD”). Pursuant to the terms of the agreement, we and King share all collaboration development costs, marketing costs and net profits derived from net sales of bremelanotide in North America based on an agreed percentage. We and King currently plan to seek a commercialization partner for bremelanotide for territories outside of North America. We have the option to create, with King, a urology specialty sales force to co-promote the product in the United States if the product is successfully developed and commercialized.

        As described in the section entitled “Recent Developments” on page 5, we have entered into an exclusive global licensing and research collaboration agreement with AstraZeneca AB (“AstraZeneca”) to discover, develop and commercialize small molecule compounds that target MC receptors for treatment of obesity, diabetes and related metabolic syndromes. We are also in the process of identifying natriuretic peptide clinical candidate compounds for the treatment of chronic congestive heart failure (“CHF”) and acutely decompensated CHF.

        In December 2005, we voluntarily suspended the sales, marketing and distribution of NeutroSpec®, our proprietary radiolabeled monoclonal antibody product for imaging and diagnosing equivocal appendicitis, and recalled all existing customer inventories. NeutroSpec, which was approved for marketing by the United States Food and Drug Administration in July 2004, was marketed and distributed by our strategic collaboration partner, Tyco Healthcare Mallinckrodt (“Mallinckrodt”). All ongoing clinical trials of NeutroSpec have been suspended. We and Mallinckrodt are evaluating future development and marketing activities involving NeutroSpec.

        Key elements of our business strategy include: entering into alliances and partnerships with pharmaceutical companies to facilitate the development, manufacture, marketing, sale and distribution of product candidates we are investigating; expanding our pipeline through the utilization of our MC expertise and patented drug discovery platform; acquiring synergistic products and technologies; and partially funding our development and discovery programs with the cash flow from our collaboration and licensing agreements.

Recent Developments

        AstraZeneca Agreement. On January 30, 2007, we entered into an exclusive global licensing and research collaboration agreement with AstraZeneca to discover, develop and commercialize small molecule compounds that target MC receptors for treatment of obesity, diabetes and related metabolic syndromes. The collaboration is based on our MC receptor obesity program and includes access to compound libraries, core technologies and expertise in MC receptor drug discovery and development.

        Under the terms of the agreement, we will receive an upfront payment of $10 million from AstraZeneca. We are eligible for milestone payments totaling up to $300 million, with up to $180 million contingent upon development and regulatory milestones and the balance on achievement of sales targets. If one or more products are approved, we will also receive royalties on sales of approved products. AstraZeneca will assume responsibility for product commercialization, product discovery and development costs, with both companies contributing scientific expertise in the research collaboration.

Other Information

        We incorporated in Delaware in 1986 and commenced operations in the biopharmaceutical area in 1996. Our corporate offices and research and development facility are located at 4C Cedar Brook Drive, Cranbury, New Jersey 08512 and our telephone number is (609) 495-2200.

RISK FACTORS

        Except for the historical information contained in this prospectus supplement or the accompanying prospectus or incorporated by reference, this prospectus supplement (and the information incorporated by reference in this prospectus supplement and the accompanying prospectus) contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those discussed here or incorporated by reference. Factors that could cause or contribute to such differences include, but are not limited to, those discussed in the section entitled “Risk Factors” beginning on page 7 of the accompanying prospectus and in the information incorporated by reference.

        Investment in our stock involves a high degree of risk. You should consider carefully the risk factors, as well as other information in this prospectus supplement and the accompanying prospectus and the documents incorporated by reference, before purchasing shares. Each of these risk factors could adversely affect our business, operating results and financial condition, as well as adversely affect the value of an investment in our stock.


FORWARD-LOOKING STATEMENTS

        Statements in this prospectus supplement, the accompanying prospectus and documents incorporated by reference, as well as oral statements that our officers, directors, or employees acting on our behalf may make, that are not historical facts, constitute “forward-looking statements,” which we make pursuant to the safe harbor provisions of Section 21E of the Exchange Act. These forward-looking statements do not constitute guarantees of future performance. Investors are cautioned that statements which are not strictly historical statements, including, without limitation,

  future financial performance,
 
  management's plans and objectives for future operations,
 
  clinical trials and results,
 
  product plans and performance,
 
  management's assessment of market factors and
 
  statements regarding our strategy and plans and those of our strategic partners,
 

constitute forward-looking statements. These forward-looking statements involve known and unknown risks, uncertainties and other factors that could cause our actual results to be materially different from our historical results or from any results expressed or implied by forward-looking statements. Our future operating results are subject to risks and uncertainties and are dependent upon many factors, including, without limitation, the risks identified under the caption “Risk Factors” in the accompanying prospectus, and in our other SEC filings.

USE OF PROCEEDS

        We estimate that the net proceeds from the sale of shares of our common stock will be approximately $25,512,000. Net proceeds will consist of the total proceeds from the sale of shares of our common stock less underwriting commissions and other expenses of the offering.

        We will use the net proceeds from the sale of shares of our common stock for general corporate purposes, including clinical trials, research and development expenses and general and administrative expenses. We have not determined the amounts we plan to spend on any of the areas listed above or the timing of these expenditures. As a result, our management will have broad discretion to allocate the net proceeds from this offering. From time to time, we evaluate the possibility of acquiring businesses, products and technologies, and we may use a portion of the proceeds as consideration for acquisitions, although we do not currently anticipate any acquisitions. Pending use, we may invest the net proceeds in interest-bearing securities.

DILUTION

        Our net tangible book value as of December 31, 2006 was $4,774,202, or approximately $0.07 per share of common stock. Net tangible book value per share represents total tangible assets less total liabilities, divided by the number of shares of common stock outstanding. Dilution in net tangible book value per share represents the difference between the amount per share paid by purchasers of common stock in this offering and the net tangible book value per share of our common stock immediately after the offering. After giving effect to the sale of shares of our common stock in this offering at the public offering price of $2.00 per share, and after deduction of the underwriting discounts and commissions and estimated offering expenses payable by us, our net tangible book value as of December 31, 2006 would have been approximately $30,286,202 or $0.36 per share. This represents an immediate increase in net tangible book value of $0.29 per share to existing stockholders and an immediate dilution in net tangible book value of $1.64 per share to purchasers of common stock in this offering.

CAPITALIZATION

        The following table sets forth our capitalization as of December 31, 2006 on an actual basis, and pro forma as adjusted to reflect the sale of the 13,750,000 shares of common stock which we are offering, less the underwriting commissions and our estimated offering expenses. You should read the information in this table together with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our financial statements and the accompanying notes incorporated by reference in this prospectus supplement and in the accompanying prospectus.

Subject to the terms and conditions stated in the underwriting agreement, we have agreed to sell to Pacific Growth Equities, LLC, as underwriter, and Pacific Growth Equities, LLC has agreed to purchase from us 13,750,000 shares of our common stock.

        The underwriting agreement provides that the obligation of the underwriter to purchase the shares included in this offering is subject to approval of legal matters by counsel and to other conditions. The underwriter is obligated to purchase all of the shares of common stock offered hereby if any of the shares are purchased.

        The underwriter proposes to offer the shares of common stock at the public offering price set forth on the cover page of this prospectus supplement. If all of the shares are not sold by the underwriter at the initial offering price, the underwriter may change the public offering price and other selling terms. In connection with the sale of the shares of common stock offered hereby, the underwriter will be deemed to have received compensation in the form of underwriting commissions.

        We, certain of our executive officers and King have agreed not to sell or transfer any common stock for 30 days after the date of this prospectus supplement without first obtaining the written consent of Pacific Growth Equities, LLC. Specifically, we, certain of our executive officers and King have agreed not to directly or indirectly offer, sell, contract to sell, grant any option to purchase, or otherwise dispose of any shares of common stock or any securities convertible into, derivative of or exercisable or exchangeable for or any rights to purchase or acquire common stock, subject to certain exceptions set forth in the underwriting agreement.

        Notwithstanding the foregoing, if (1) during the last 17 days of the 30-day period after the date of the underwriting agreement, we issue an earnings release or publicly announce material news or if a material event relating to us occurs or (2) prior to the expiration of the 30-day period after the date of the underwriting agreement, we announce that we will release earnings during the 16-day period beginning on the last day of the 30-day period, the above restrictions will continue to apply to us, certain of our executive officers and King until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

Table of Contents

        The following table shows the underwriting commissions that we will pay in connection with this offering.

       
Per Share
  Total      
  Public offering price   $2.00    $27,500,000      
  Underwriting commission   $0.11    $1,512,500      
  Proceeds to us, before expenses   $1.89    $25,987,500      

        We have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments the underwriter may be required to make because of any of those liabilities.

        We will pay Rodman & Renshaw, LLC an advisory fee of $275,000 in connection with this offering.

        We estimate that the total expenses of this offering, including legal, accounting, printing, AMEX, transfer agent, the fee to be paid to Rodman & Renshaw, LLC, and other miscellaneous fees and expenses, but not including the underwriting commissions, will be approximately $475,500 and will be payable by us.

        The underwriter has advised us that it may engage in activities that stabilize, maintain or otherwise affect the price of the shares, including:

    stabilizing transactions,

    short sales and

    purchases to cover positions created by short sales.

        Stabilizing transactions consist of bids or purchases made, pursuant to Regulation M of the federal securities laws, for the purpose of preventing or retarding a decline in the market price of the shares while this offering is in progress. Stabilizing transactions may include making short sales of the shares, which involves the sale by the underwriter of a greater number of shares than it is required to purchase in this offering, and purchasing shares in the open market to cover positions created by short sales.

        Purchases to cover short positions and stabilizing transactions may have the effect of preventing or slowing a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. Neither we nor the underwriter makes any representation or prediction as to the effect that the transactions described may have on the price of the shares. The underwriter has advised us that stabilizing bids, short sales and open market purchases may be effected on the AMEX or otherwise and, if commenced, may be discontinued at any time.

        In connection with this offering, the underwriter may distribute copies of this prospectus supplement and the accompanying prospectus electronically.
