Collegium Announces Publication of Data on the Durability of Pain Relief with Xtampza ER

CANTON, Mass., April 07, 2016 -- Collegium Pharmaceutical, Inc. (Nasdaq:COLL) today announced the publication of an analysis of the duration of effect of Xtampza™ ER administered every 12 hours during the Double-blind Maintenance Phase of a multicenter, 12-week clinical study.  The publication is titled, “Evaluation of the Durability of Pain Relief Throughout a 12-Hour Dosing Interval of a Novel, Extended-Release, Abuse-Deterrent Formulation of Oxycodone – Oxycodone DETERx^®” and is published in the peer-reviewed journal, Current Medical Research and Opinion.

The analysis of the data from the Phase 3 randomized withdrawal, double-blind, placebo-controlled, enriched-enrollment, parallel-group, multicenter, 12-week clinical study in patients with chronic low back pain showed limited use of acetaminophen, the only rescue medication used in the study.  In addition, the analysis showed no increase in rescue medication consumption from 8 to 12 hours after dosing, which is the time interval commonly associated with end-of-dose failure leading to inadequate analgesic effect; these data suggest that subjects maintained pain relief over the entire dosing interval with twice daily administration of Xtampza ER.

"The results of this analysis suggest that Xtampza ER may provide clinicians an effective 12-hour, twice daily, formulation of oxycodone for their patients with chronic pain who require continuous, around-the-clock opioid analgesia for an extended period of time,” stated Dr. Sri Nalamachu, lead author on the publication and President and Medical Director for the International Clinical Research Institute, Inc. “It is also encouraging that patients were able to achieve adequate and sustained pain relief with minimal use of rescue medications.”
