BioDelivery Sciences: U.S. Fda Approves Belbuca (Buprenorphine) Buccal Film FOR CHRONIC PAIN MANAGEMENT

The following excerpt is from the company's SEC filing.

New treatment option combines proven efficacy and established safety profile of buprenorphine with a novel delivery system that adds convenience and flexibility

DUBLIN and RALEIGH, N.C., October 26, 2015

Endo Pharmaceuticals Inc., a subsidiary of Endo International plc (NASDAQ: ENDP) (TSX: ENL), and BioDelivery Sciences International, Inc. (NASDAQ: BDSI), announced today that the U.S. Food and Drug Administration (FDA) has approved BELBUCA (buprenorphine) buccal film for use in patients with chronic pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which a lternative treatment options are inadequate. BELBUCA, which is the first and only buprenorphine developed with a dissolving film that is absorbed through the inner lining of the cheek for chronic pain management, is expected to be commercially available in the U.S. during the first quarter of 2016 in seven dosage strengths, allowing for flexible dosing ranging from 75 µg to 900 µg every 12 hours. This enables physicians to individualize titration and treatment based on the optimally effective and tolerable dose for each patient.

The availability of new, convenient and flexible treatment options is important for patients whose lives are burdened by chronic pain, a debilitating condition that affects more Americans than diabetes, heart disease and cancer combined, said Richard L. Rauck, M.D., Director of Carolinas Pain Institute, Winston Salem, NC. BELBUCA provides a unique approach for chronic pain management, combining the proven efficacy and established safety of buprenorphine with a novel buccal film delivery system that adds convenience and flexibility. For both opioid-naïve and opioid-experienced patients1 who require around-the-clock treatment and for whom alternative treatment options are inadequate, BELBUCA offers appropriate, consistent pain relief and a low incidence of typical opioid-like side effects.

BELBUCA is a mu-opioid receptor partial agonist and a potent analgesic with a long duration of action that utilizes BDSIs patented BioErodible MucoAdhesive (BEMA

) drug delivery technology. Through this unique delivery system, buprenorphine is efficiently and conveniently delivered across the buccal mucosa (inside lining of the cheek). Buprenorphine is a Schedule III controlled substance, meaning that it has been defined as having lower abuse potential than Schedule II drugs, a category that includes most opioid analgesics. Among chronic pain patients taking opioids, the vast majority are on daily doses of 160 mg of oral morphine sulfate equivalent (MSE) or less. With seven dosage strengths up to 160 mg MSE, BELBUCA

offers a treatment choice for a wide range of opioid needs in chronic pain sufferers.

The FDA approval of BELBUCA

represents an important and meaningful milestone for Endo Pharmaceuticals, demonstrating our strength in bringing a valuable new therapy from pipeline through approval. Our advancement of BELBUCA also underscores Endos long-standing heritage of innovation and its commitment to supporting the pain community, said Rajiv De Silva, President and CEO of Endo. We are proud to add BELBUCA to our diversified portfolio of branded and generic products and we look forward to preparing for the expected U.S. launch of the drug in early 2016.

The FDA approval of BELBUCA was based on two double-blind, randomized, placebo-controlled, enriched-enrollment Phase 3 studies in patients with moderate to severe chronic low back pain. In these pivotal trials, a total of 1,559 opioid-experienced (study BUP-307) and opioid-naïve (study BUP-308) patients received study drug. The trials included an open-label period in which patients were titrated to a tolerated, effective dose of BELBUCA and then randomized to either continue on BELBUCA or receive a placebo buccal film.

In both studies, BELBUCA demonstrated a consistent, statistically significant improvement in patient-reported pain relief at every week from baseline to week 12, compared to placebo. The most common adverse reactions (

5%) reported by patients with BELBUCA

in the clinical trials were nausea, constipation, headache, vomiting, fatigue, dizziness, somnolence, diarrhea, dry mouth, and upper respiratory tract infection.

We are excited about the FDA approval of BELBUCA

as we believe it is a testament to the strength of BDSIs...
