News Release - February 17, 2006
ORADUR(TM) Technology Milestone: Remoxy(TM) (ORADUR-based oxycodone) Receives Special Protocol Assessment and Commences Pivotal Phase IIICUPERTINO, Calif., Feb. 17 (HSMN NewsFeed) -- DURECT Corporation (Nasdaq: DRRX ) reported today that Remoxy(TM), an abuse-resistant pain medicine under development based on DURECT's patented ORADUR(TM) technology incorporating the opioid oxycodone has successfully completed a Special Protocol Assessment with the U.S. Food and Drug Administration (FDA) and that a pivotal Phase III trial is being commenced on Remoxy in 400 patients with severe chronic pain. The events were announced on February 16 by King Pharmaceuticals, Inc. (NYSE: KG ), the company which will be commercializing Remoxy, if approved, and Pain Therapeutics, Inc. (Nasdaq: PTIE ), DURECT's licensee of the rights to Remoxy and other ORADUR-based products incorporating oxycodone and three other opioid compounds.
Dr. Brown continued, "We are also delighted with the continued advancement of our ORADUR technology platform, and are excited about its potential as a platform for numerous other innovative products given its unique combination of sustained-release and abuse-resistant properties. We look forward to developing additional innovative sustained release oral gel-cap products that utilize opioids not subject to our alliance with Pain Therapeutics and King and other active agents prone to abuse."
Special Protocol Assessment
A Special Protocol Assessment (SPA) from the FDA specifies the Phase III trial objective, design, clinical endpoints and analyses needed to support regulatory approval. These features are considered binding, i.e., the FDA will not later alter its perspective unless public health concerns unrecognized at the time of protocol assessment under this process are evident. For more information please visit the FDA website: www.fda.gov/CbER/gdlns/protocol.pdf.
Phase III Trial Details (as announced by Pain Therapeutics and King Pharmaceuticals)
Under the terms of the SPA for Remoxy, one pivotal Phase III trial is required to file a New Drug Application. The randomized, double-blinded, placebo-controlled, multi-center pivotal trial will enroll 400 patients with moderate-to-severe osteoarthritic pain in multiple U.S. clinical sites. Following a titration period, patients will be randomized to either Remoxy (10-80 mg daily) or placebo for 12 weeks. The primary endpoint is reduction in pain scores over three months compared to baseline. Patient accrual is expected to begin shortly and continue through year end 2006.
ORADUR sustained released oral gel-cap technology provides the unique characteristics of Remoxy and the referenced follow-on products. 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.
Remoxy is an oral, long-acting oxycodone capsule under development by Pain Therapeutics, Inc. and King Pharmaceuticals, Inc. that incorporates several abuse-deterrent properties and offers the convenience of twice-a-day dosing. Remoxy is formulated with DURECT Corporation's ORADUR technology under a development and license agreement between DURECT and Pain Therapeutics. Under the terms of the license agreement between Pain Therapeutics and DURECT, Pain Therapeutics has exclusive worldwide rights to develop and to commercialize Remoxy and other ORADUR-based products using three other opioid drugs. DURECT is reimbursed for formulation and other work performed under its agreement with Pain Therapeutics, and will receive milestone payments based on the achievement of certain technical, clinical or regulatory milestones, in addition to receiving royalties on end product sales. Pain Therapeutics has sublicensed the commercialization rights of Remoxy to King Pharmaceuticals. Oxycodone is the active drug ingredient in Remoxy and in the branded product OxyContin®. OxyContin®, the leading brand name opioid used in the treatment of moderate-to-severe pain, has U.S. sales of nearly $2 billion for the 12-months ending August 2005, according to IMS Health data. Drug abusers can easily extract oxycodone from OxyContin® tablets in order to induce a quick and powerful euphoric high. Oxycodone abusers risk respiratory depression, which can be fatal, and opioid addiction.
