Titan Pharmaceuticals, Inc. and partner Braeburn Pharmaceuticals today announced that the U.S. Food and Drug Administration has scheduled a meeting of the Psychopharmacologic Drugs Advisory Committee (PDAC) on Jan. 12, 2016 to review the New Drug Application (NDA) for Probuphine┬« for the maintenance treatment of opioid addiction. The meeting notice appears in today's Federal Register and can be found at http://federalregister.gov/a/2015-30970. The NDA was resubmitted to the FDA in August 2015, and accepted by the FDA in September 2015. An agency action date has been set for Feb. 27, 2016.

"The data from the final phase 3 trial, which was designed in collaboration with the FDA in response to questions raised in the complete response letter, is compelling and we look forward to presenting it on January 12," said Braeburn Pharmaceuticals President and CEO Behshad Sheldon. "More long-term treatments are needed to help people stay in recovery, and we remain excited about the potential for Probuphine to be the first of many new options for people with opioid addiction."

"The Braeburn team has been interacting closely with the FDA, and we continue to support them as the Probuphine NDA advances," said Titan Pharmaceuticals President Sunil Bhonsle. "We look forward to a successful meeting."

About Probuphine®

Probuphine is an investigational subdermal implant designed to deliver buprenorphine continuously for six months following a single treatment, and to promote patient compliance and retention. Buprenorphine, which is the active ingredient in multiple FDA-approved drug products for the treatment of opioid addiction, is currently available in tablet and film formulations that require self-administration by patients on a daily basis.

Probuphine was developed using ProNeura™, Titan's continuous drug delivery system that consists of a small, solid implant made from a mixture of ethylene-vinyl acetate (EVA) and a drug substance. The resulting construct is a solid matrix that is placed subdermally, normally in the upper arm in an outpatient office procedure, and removed in a similar manner at the end of the treatment period.

The efficacy and safety of Probuphine has been studied in several clinical trials, including the double blind, double dummy final Phase 3 study, which provided positive results (announced June 2015) in the comparison of maintenance treatment with Probuphine to maintenance treatment with daily sublingual buprenorphine in stable patients receiving a daily dose of 8mg or less of buprenorphine; the previously reported 163-patient, placebo-controlled study over a 24-week period (published in the Journal of the American Medical Association (JAMA)), and a follow-on study of 287 patients (published in the journal Addiction).
