Collegium Announces FDA Advisory Committees Unanimously Recommend Approval of Xtampza ER(TM), an Abuse-Deterrent Analgesic for Chronic Pain

CANTON, Mass., Sept. 11, 2015 (GLOBE NEWSWIRE) -- Collegium Pharmaceutical, Inc. (NASDAQ:COLL) today announced that the Anesthetic and Analgesic Drug Products Advisory Committee and Drug Safety and Risk Management Advisory Committee of the U.S. Food and Drug Administration (FDA) voted unanimously to support the approval of Xtampza ER™ (oxycodone extended-release capsules) for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate.

Xtampza ER, Collegium's lead product candidate, is an abuse-deterrent, extended-release, oral formulation of oxycodone, a widely prescribed opioid medication. The FDA will consider the advisory committees' recommendation as it continues its review of Xtampza ER. The FDA set a Prescription Drug User Fee Act, or PDUFA, goal date of October 12, 2015 for completion of its review of the Xtampza ER New Drug Application (NDA).

"We are very pleased that the FDA advisory committees recommended approval for Xtampza ER," said Michael Heffernan, Collegium's Chairman and CEO. "We look forward to working with the FDA as it finalizes its review."

About Xtampza ER

Collegium's lead product candidate, Xtampza ER, is an abuse-deterrent, extended-release, oral formulation of oxycodone in development for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. The active ingredient in Xtampza is oxycodone, which is approved by the FDA and other regulators around the world in a number of both immediate-release and extended-release drug products. Collegium developed Xtampza using its proprietary DETERx abuse-deterrent technology to address common methods of abuse, including chewing, crushing and/or dissolving, and then taking it orally or snorting or injecting Xtampza ER.

Collegium's preclinical studies and clinical trials have shown that the contents of the Xtampza capsule can be removed from the capsule and sprinkled on food, directly into the mouth or administered through feeding tubes, without compromising their drug release profile, safety or abuse-deterrent characteristics. By contrast, OxyContin OP, which is formulated in hard tablets, has a black box warning label stating that crushing, dissolving or chewing can cause rapid release and absorption of a potentially fatal dose of the active ingredient. Collegium believes that Xtampza, if approved, can address the pain management needs of the approximately 11 million patients in the United States who suffer from chronic pain and have difficulty swallowing.
