Study to Evaluate the Effect of AFQ056 in Obsessive Compulsive Disorder (OCD) Patients Resistant to Selective Serotonin Reuptake Inhibitor (SSRI) Therapy

This was a randomized, double-blind, parallel group, placebo-controlled, 12-weeks 200 mg b.i.d oral dose treatment of AFQ056 (following a 4 week up-titration period and followed by a 3 week down-titration period) or matched placebo in patients diagnosed with OCD and on background SSRI treatment for at least 12 weeks. Study was prematurely terminated at the time of the first Interim Analysis (IA) as the study did not meet its primary efficacy objective.
