CUPERTINO, Calif., Aug 02, 2006 /PRNewswire-FirstCall via COMTEX News Network/ -- DURECT Corporation (Nasdaq: DRRX) reported today the initiation of a Phase I clinical trial for a new ORADUR-based opioid drug candidate. This new drug candidate is the second ORADUR-based opioid drug to undergo clinical testing by King Pharmaceuticals, Inc., the company which will be commercializing the drug candidate, if approved, and Pain Therapeutics, Inc., DURECT's licensee of the rights to the drug candidate and other ORADUR-based products incorporating oxycodone and three other opioid compounds. The first drug candidate under development by Pain Therapeutics and King Pharmaceuticals, Remoxy (ORADUR-based oxycodone), is currently in Phase III clinical testing. According to Pain Therapeutics and King Pharmaceuticals, the investigational new drug (IND) application for this new drug candidate has been accepted by the U.S. Food and Drug Administration (FDA). The active pharmaceutical drug in the new ORADUR-based opioid drug candidate has not been disclosed.

"We are very delighted with the advancement of our ORADUR technology platform and look forward to the continued progress of all of the products under the King Pharmaceuticals and Pain Therapeutics alliance," stated James E. Brown, DVM, President and Chief Executive Officer. "Furthermore, we look forward to developing additional innovative sustained release oral gel-cap products that utilize other opioids and other active agents prone to abuse."
ORADUR sustained released oral gel-cap technology provides the unique characteristics of Remoxy and the other opioid drug candidates subject to the Pain Therapeutics and King Pharmaceuticals alliance. Products based on the ORADUR technology can take the form of an easy to swallow gelatin capsule that uses a high-viscosity base component, SABER(TM), to provide sustained release of active ingredients for a period of from 12 to 24 hours of drug delivery. Oral dosage forms based on the ORADUR gel-cap may also have the added benefit of being less prone to abuse than other controlled release dosage forms on the market today. ORADUR-based products can be manufactured by a simple process using conventional methods making them readily scalable. These properties have the potential to make ORADUR-based products an attractive option for pharmaceutical companies that seek to develop tamper and abuse resistant oral products.
