US specialty pharma company Collegium Pharmaceutical (Nasdaq: COLL) saw its shares rise 3.9% to $17.48 after its announced positive top-line from a clinical trial evaluating the abuse potential of its Xtampza ER (oxycodone extended-release capsules) compared to chewed Xtampza ER, and crushed immediate-release oxycodone in solution in non-dependent, recreational drug abusers.

The study met its primary and secondary endpoints of lower “Drug Liking” and “Take Drug Again.”

The results demonstrated that intact and chewed Xtampza ER (fed or fasted) had statistically significantly lower peak "Drug Liking" (Emax) when compared with crushed immediate-release oxycodone. Furthermore, Xtampza ER when taken chewed was bioequivalent to taking it intact as determined by Cmax and AUC.
