CUPERTINO, Calif., Nov. 11, 2014 /PRNewswire/ — DURECT Corporation (Nasdaq: DRRX) announced that it has received meeting minutes from its face-to-face meeting with the FDA on September 23, 2014 regarding the POSIDUR program.   In the February 2014 Complete Response Letter (CRL), FDA indicated that multiple safety trials would be required to support a broad indication.  DURECT inquired whether it would be possible to expedite approval by pursuing an initial indication of soft tissue post-surgical analgesia without conducting additional trials.  FDA has indicated that in this scenario, it should be acceptable to conduct only one additional soft tissue clinical trial, the size of which is not yet defined, to generate the data required for product approval, including safety data for POSIDUR compared to a non-SABER containing comparator(s) and also product efficacy (to go along with the efficacy already demonstrated in our pivotal hernia trial).

“Based on the Complete Response Letter we anticipated that we would be required to do additional safety trials,” stated James Brown, President and CEO of DURECT.  “Over the coming months, we expect to have further communications with the FDA to refine the path forward.”


POSIDUR is an investigational post-operative pain relief depot that utilizes our patented SABER technology and is intended to deliver bupivacaine to provide up to three days of pain relief after surgery.  We are in discussions with potential partners regarding licensing development and commercialization rights to POSIDUR, for which we hold worldwide rights, while at the same time we are preparing to be in a position to commercialize POSIDUR ourself in the U.S. in the event that we determine that is the preferred route of commercialization.

On February 12, 2014 we received a Complete Response Letter for POSIDUR from the FDA.  Based on its review, the FDA has determined that they cannot approve the NDA in its present form, stating the NDA does not contain sufficient information to demonstrate that POSIDUR is safe when used in the manner described in the proposed label, and the FDA indicated that additional clinical safety studies need to be conducted.
