Webcast Conference Call Scheduled for 8:30 a.m. EDT Today


Sep 26, 2005, 01:00 ET from Corgentech Inc.

/PRNewswire-FirstCall/ -- Corgentech Inc. (Nasdaq:   CGTK) and AlgoRx
 Pharmaceuticals, Inc. today announced that they have entered into a definitive
 merger agreement to create a late-stage company with a deep pipeline of
 clinical products that will be largely focused on developing and
 commercializing products for pain management and inflammation.
     The combined company will have four products in its pipeline.  AlgoRx's
 portfolio of pain management drug candidates includes ALGRX 3268, which is in
 Phase 3 clinical trials, ALGRX 4975, which is in Phase 2 clinical trials, and
 ALGRX 1207, which is soon to enter the clinic.  Corgentech continues to
 develop NF-kappaB Decoy, which is in two Phase 1/2 trials for the treatment of
     Under the terms of the agreement, Corgentech will issue, and AlgoRx
 stockholders will receive in a tax-free exchange, shares of Corgentech common
 stock such that AlgoRx stockholders will own approximately 62 percent of the
 combined company on a pro forma basis and Corgentech stockholders will own
 approximately 38 percent.  The agreement and plan of merger has been approved
 by both boards of directors and will need to be approved by the companies'
     "We believe that the combination of Corgentech and AlgoRx will add
 significant value for our stockholders by dramatically bolstering our product
 pipeline with late-stage product candidates that bring us closer to
 commercialization," stated John P. McLaughlin, chief executive officer of
 Corgentech.  "We are also optimistic about the potential of our NF-kappaB
 Decoy product candidate for eczema and believe that the combination of the two
 companies offers diversification for stockholders of both companies."
     "By combining the financial resources of the two companies and the
 expertise of the two management teams, which include significant experience in
 regulatory affairs, clinical trials management and product marketing and
 commercialization, we believe that our late-stage products in pain management
 will be more expeditiously commercialized," stated Ronald M. Burch, M.D.,
 Ph.D., chief executive officer of AlgoRx.  "This merger may enable us to file
 a New Drug Application (NDA) for our lead product candidate, ALGRX 3268 for
 topical local anesthesia in 2006."
     With a seasoned management team and $124 million in cash, cash equivalents
 and short-term investments in the combined companies at the end of the second
 quarter, the company would also have a deep pipeline of four product
 candidates after the approval of the merger:
      --  ALGRX 3268 represents a near-term product opportunity, which is
          expected to complete Phase 3 trials in 2005 and file an NDA during
          2006.  The product is for topical local anesthesia and is aimed at
          reducing the pain associated with needlesticks for venipunctures
           (blood draws) and intravenous line placements.  ALGRX 3268 is based
          on a needleless injection system called Powderject(R), which
          accelerates lidocaine particles into the epidermis in order to
          anesthetize nerves.  The product, which may be especially useful in
          pediatric populations and emergency room settings, is easy to use and
          anesthetizes quickly -- generally in one minute -- offering an
          important advantage over currently available therapies.
      --  ALGRX 4975, a VR1 agonist, is being developed for site-specific,
          severe or intractable pain.  These types of pain are poorly treated
          by existing drugs such as opioids, and use of ALGRX 4975 could result
          in the reduction in opioid side effects as well as shorter
          rehabilitation and shorter hospital stay.  Phase 2 clinical trials
          are currently underway for post-surgical pain following a variety of
          surgeries including bunionectomies, total knee replacements and
          various abdominal surgeries.  Additional Phase 2 trials are underway
          for Morton's neuroma and tendonitis.  Its advantages over currently
          available therapies are that it is non-opioid based and it is
          long-acting, providing pain relief to many patients for weeks or
          months after a single treatment.  ALGRX 4975 is a C-neuron
          anesthetic, based on capsaicin.  The product is administered locally
          at the site of pain and selectively reduces pain in nerve endings.
      --  NF-kappaB Decoy is currently being evaluated in Phase 1/2 clinical
          trials for the inflammatory skin condition, eczema.  Two multi-center
          trials are currently underway -- one in the United States and the
          other in Australia and Switzerland -- evaluating the company's
          NF-kappaB Decoy across nearly 200 patients.  Clinical data are
          expected to be presented in the first quarter of 2006.  NF-kappaB
          Decoy is a highly selective and potent inhibitor of the NF-kappaB
          transcription factor, which is implicated in inflammatory diseases
          such as eczema, asthma and inflammatory bowel disease.
      --  ALGRX 1207 is a new class of anesthetic that is undergoing
          preclinical development as a topical local anesthetic.  This product
          is expected to enter clinical trials for cutaneous neuropathic pain,
          such as chemotherapy-induced neuropathy, in 2006.  This product
          candidate acts by binding to the fast sodium channel and may have a
          faster onset and longer duration of action as well as improved
          penetration when compared with products currently on the market.
     Leadership and Organizational Structure
     Pending stockholder approval of the merger, the board of directors of the
 combined company will be comprised of Richard B. Brewer, Dr. Charles M. Cohen,
 Thomas J. Colligan, Carter H. Eckert, Dr. Rodney A. Ferguson, John P.
 McLaughlin, Dr. Arnold L. Oronsky and Dr. Michael F. Powell.  The management
 team of the combined company will be led by John McLaughlin as chief executive
 officer.  Dr. Ronald Burch will serve as vice president of development, and
 Richard P. Powers will serve as chief financial officer.  Both the Corgentech
 and AlgoRx facilities are expected to be retained with Corgentech's South San
 Francisco facility becoming the company's headquarters.  Corgentech and AlgoRx
 currently have approximately 95 total employees, and the combined management
 team will work to integrate the two companies as well as to identify synergies
 and redundancies across the combined organization.
     Election of James Huang to President
     James Z. Huang, Corgentech's senior vice president of business development
 and commercial operations, has been elected to the position of president.  Mr.
 Huang has been with Corgentech for three years and will have responsibility
 for commercial and other operations within the company.  In addition, he will
 coordinate integration relating to the merger announced today.  Mr. Huang has
 successfully negotiated multiple collaborations for the company, two of which
 include this merger agreement and the company's former worldwide partnership
 with Bristol-Myers Squibb.  He was with Tularik prior to Corgentech and prior
 to that held various positions with Alza Corporation, Bristol-Myers Squibb and
 SmithKline Beecham PLC (now GlaxoSmithKline) where he launched several
 products including the billion dollar product, Avandia.
     Deal Timeline
     The companies expect to file an S-4 and related joint proxy statement with
 the Securities and Exchange Commission and any other necessary government
 filings in the coming weeks.  Depending upon the review process of the
 agencies, the companies would expect the stockholder vote to occur in late
 December or early January.  Lazard Freres & Co. LLC served as financial
