CUPERTINO, CA, June 27, 2007/ PRNewswire-First Call via COMTEX/ — DURECT Corporation (Nasdaq: DRRX) announced today that Endo Pharmaceuticals Inc. (Nasdaq: ENDP) has commenced its Phase II clinical program designed to evaluate the conversion of patients being treated with various opioids to sufentanil patches utilizing DURECT’s TRANSDUR™ technology. DURECT had previously announced positive results from an initial Phase II clinical study conducted by DURECT utilizing patches made by DURECT; that earlier study was an open label study designed to evaluate the transition of chronic pain patients from Duragesic® (transdermal fentanyl patch) to the sufentanil patch.
“This is an important step forward for this program. Because the sufentanil patch is designed for once-a-week dosing, we believe it will provide meaningful patient benefits if approved,” stated James Brown, President and CEO of DURECT Corporation.
DURECT’s proprietary sufentanil patch is intended to provide extended chronic pain relief for up to seven days from a single application, as compared to the three days of relief provided with currently available opioid patches. DURECT anticipates that the small size of the sufentanil patch, potentially as small as 1/5th the size of currently marketed transdermal fentanyl patches for a therapeutically equivalent dose, may offer improved convenience and compliance for patients.
In March 2005, DURECT entered into an agreement granting Endo exclusive rights to develop, market and commercialize the sufentanil patch in the U.S. and Canada.
