BDSI Announces Positive Key Secondary Efficacy Endpoint Results for Bema Fentanyl

MORRISVILLE, N.C.--(BUSINESS WIRE)--May 14, 2007 - BioDelivery Sciences International, Inc. (Nasdaq: BDSI) announced additional statistically significant results with BEMA Fentanyl in cancer patients with breakthrough pain in its Phase III efficacy clinical trial for the product.

Results were based on the company's continuing analysis of the secondary efficacy endpoints from the study. A key secondary endpoint was the SPID 15 (Summary of Pain Intensity Difference at 15 minutes), a measure of the speed of onset of the medication. The study data indicate that the SPID 15 was significantly higher on BEMA(TM) Fentanyl than with placebo.

On April 25, 2007, BDSI announced statistically significant results of its primary efficacy endpoint for the BEMA(TM) Fentanyl Phase III trial, SPID 30 (Summary of Pain Intensity Difference at 30 minutes). BEMA(TM) Fentanyl consists of a small, dissolvable polymer disc, formulated with the opioid narcotic fentanyl, for application to the buccal (inner lining of cheek) membranes. Upon administration, BEMA(TM) Fentanyl is designed to deliver a rapid, reliable dose of drug across the mucous membranes.

In addition to the SPID 15 endpoint, the company also reported that the overall global analysis of the treatment, which represents each patient's overall satisfaction with the product, was also found to be statistically superior to the placebo.

Dr. Andrew Finn, BDSI's Executive Vice President of Product Development, stated: "We are very pleased with the outcome of the results from our current secondary endpoint analyses from our Phase III efficacy study which, as previously announced, we plan to present along with other efficacy and safety data at an upcoming scientific forum to be determined. We are particularly pleased to see that the onset of analgesia with BEMA(TM) Fentanyl is rapid, since a quick onset of action is one of the anticipated features of delivering fentanyl through the mucosal membrane and a major need for our target patients."

Dr. Mark Sirgo, President and CEO of BDSI, commented: "These additional efficacy results continue to define the profile of BEMA(TM) Fentanyl in treating breakthrough cancer pain. Based on the combination of what we believe is a convenient and comfortable delivery form with the early pain intensity reduction demonstrated in our study, we remain confident that BEMA(TM) Fentanyl has the potential to play an important role in the future treatment of breakthrough cancer pain. Based on this additional efficacy information, and assuming NDA acceptance and approval by FDA and that our development and commercialization activities will continue as planned, we continue to believe we will ultimately reach our annual peak sales projection of $250 million for the treatment of breakthrough cancer pain."

BDSI recently announced that the New Drug Application (NDA) for BEMA(TM) Fentanyl is scheduled for submission during the third quarter of 2007. Prior to this submission, BDSI will conduct a pre-NDA meeting with the FDA on June 28, 2007 to discuss results of the efficacy trial, along with the safety data and other requirements for the NDA submission.

About the BEMA(TM) Technology

BDSI's BEMA(TM) drug delivery technology consists of a dissolvable, dime-sized polymer disc for application to the mucosal (inner lining of cheek) membrane. BEMA(TM) discs deliver a rapid, reliable dose of drug across mucous membranes for time-critical conditions or trauma cases where intravenous lines or injections are unavailable or not practical.

About BEMA(TM) Fentanyl

BDSI's lead product under development is BEMA(TM) Fentanyl, a treatment for "breakthrough" cancer pain (i.e., episodes of severe pain which "break through" the medication used to control the persistent pain). BDSI believes there is a clear need and growing market for additional narcotic agents in alternative dosage forms to provide rapid pain relief. Fentanyl belongs to the group of medicines called narcotic analgesics, which are used to relieve pain. The transmucosal form of fentanyl is a powerful narcotic used to treat breakthrough cancer pain. BDSI believes that fentanyl applied with its BEMA(TM) disc technology has the potential to meet the market need for new narcotics and, BDSI believes, will be well suited for breakthrough cancer pain in opioid-tolerant patients.
