WALTHAM, Mass.--(BUSINESS WIRE)--Alkermes, Inc. (NASDAQ: ALKS) today announced positive topline results from a phase 1b, double-blind, randomized, placebo-controlled study of ALKS 9070 in patients with schizophrenia.

Data from the study showed that ALKS 9070 was generally well tolerated, achieved therapeutically relevant plasma concentrations of aripiprazole with a pharmacokinetic profile that supports once-monthly dosing. Based on these results, Alkermes plans to advance ALKS 9070 into pivotal development by the end of calendar 2011.
