  Purpose

AVE1625 is a new potent and selective cannabinoid 1 (CB1) antagonist in clinical development for the treatment of cognitive impairment in patients diagnosed with schizophrenia.

The main objective of this study is to evaluate the efficacy on cognitive impairment of 3 doses of AVE1625 using a new cognitive battery called MATRICS (Measurement and Treatment Research to Improve Cognition in Schizophrenia) in schizophrenic patients.

The secondary objectives are to measure the efficacy of AVE1625 on functional capacity of the patients using a specific scale called UPSA2 (University of California San Diego Performance-based Skills Assessment 2) and to assess the safety of the compound.
