Collegium Announces Publication of Nasal Human Abuse Potential Study in American Academy of Pain Medicine

CANTON, Mass., Dec. 16, 2015 (GLOBE NEWSWIRE) -- Collegium Pharmaceutical, Inc. (Nasdaq:COLL) today announced the publication of results from the intranasal human abuse potential of Xtampza™ ER (oxycodone) extended-release capsules. The publication is titled “A Randomized, Double-Blind, Double-Dummy Study to Evaluate the Intranasal Human Abuse Potential and Pharmacokinetics of a Novel Extended-Release Abuse-Deterrent Formulation of Oxycodone.”

In the published study, intranasal administration of crushed Xtampza ER was compared with oral administration of intact Xtampza ER and with intranasal administration of crushed immediate-release (IR) oxycodone in non-dependent, non-tolerant recreational opioid users (n=36). The primary endpoint for the study was Drug Liking at this moment from the Drug Effects Questionnaire, measured up to 24 hours after dosing using a bipolar visual analogue scale (VAS). Xtampza ER (both crushed intranasal and intact oral) had significantly lower maximum (peak) drug liking (Emax) when compared with intranasal crushed IR oxycodone (p ≤ 0.0001). Furthermore, when comparing Xtampza ER treatments, Emax for drug liking after administration of crushed intranasal Xtampza ER was significantly lower than for intact oral administration of Xtampza ER (p ≤ 0.05).

Dr. Lynn Webster, lead author on the publication and Vice President of Scientific Affairs, PRA Health Sciences (Raleigh, NC), stated, "This study presents the first pharmacokinetic and pharmacodynamic data showing that crushing Xtampza ER and administering it nasally is not associated with increased Drug Liking scores when compared with taking the drug as intended, via oral administration. The data from this study was included in the Xtampza ER NDA and is intended to support abuse-deterrent labeling upon final approval."

About Collegium Pharmaceutical, Inc.

Collegium is a specialty pharmaceutical company focused on developing a portfolio of products that incorporate its patent-protected DETERx® technology platform for the treatment of chronic pain and other diseases. The DETERx oral drug delivery technology is designed to provide extended-release delivery, unique abuse-deterrent properties, and flexible dose administration options.

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. Collegium developed Xtampza using its proprietary DETERx technology platform to address common methods of abuse, including chewing, crushing and/or dissolving, and then taking it orally or snorting or injecting.

The United States Food and Drug Administration (FDA) has granted tentative approval to the Company's New Drug Application (NDA) for Xtampza ER 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. With a tentative approval, the FDA has determined that Xtampza ER meets required quality, safety and efficacy standards for approval but it is subject to an automatic stay of up to 30 months as a result of patent litigation filed by Purdue Pharma, L.P.
