CUPERTINO, Calif., Aug. 6, 2012 /PRNewswire/ -- DURECT Corporation (Nasdaq: DRRX) today announced that it has completed its pre-NDA communications with the United States Food and Drug Administration (FDA) regarding POSIDUR ™ (SABER ®-Bupivacaine). Through this process, DURECT has received guidance and thoughtful comments from the FDA covering various chemistry, manufacturing, non-clinical, clinical pharmacology, clinical, statistical and product labeling topics based on our pre-NDA meeting questions. We have sent to the FDA meeting minutes and are awaiting their final concurrence on those minutes. With the input we have received from the FDA, DURECT intends to prepare and submit a new drug application (NDA) under 505(b) with the FDA in late 2012 or early 2013. POSIDUR is our investigational post-operative pain relief depot that utilizes our patented SABER technology to deliver bupivacaine and is designed to provide up to three days of pain relief after surgery.

About POSIDUR ™POSIDUR is our investigational post-operative pain relief depot that utilizes our patented SABER ® technology to deliver bupivacaine and is designed to provide up to three days of pain relief after surgery. In the U.S., POSIDUR is covered by two patent families, which include granted patents expiring in at least 2015 and 2025, respectively. In Europe, POSIDUR is covered by two granted patents expiring in 2016 and 2025, respectively, plus any eligible patent term extensions. We currently hold worldwide commercialization rights to POSIDUR. About SABER ® Technology The SABER technology is a patented extended-release technology that can be formulated for systemic or local administration of active agents via the parenteral or oral route. We believe that our SABER system can provide the basis for the development of state-of-the-art biodegradable, extended-release injectables. The SABER system uses a high-viscosity base component, such as sucrose acetate isobutyrate (SAIB), to provide extended release of a drug. When the high viscosity SAIB is formulated with drug, biocompatible excipients and other additives, the resulting formulation is liquid enough to administer easily with standard syringes. After administration of a SABER formulation, excipients diffuse away, leaving a viscous depot. Depending on how it is formulated, the SABER system can successfully deliver therapeutic levels of a wide spectrum of drugs from one day to three months from a single administration.
