A Study of the Effect of RO4917838 on Biomarker Measures of Cognitive Dysfunction in Patients With Schizophrenia and Schizoaffective Disorder
A Randomized, Double-blind, Placebo-controlled Parallel Arm Study of the Effect of RO4917838 on Biomarker Measures of Cognitive Dysfunction in Schizophrenia and Schizoaffective Disorder

This randomized, double-blind, placebo-controlled parallel group study will assess the effect on biomarkers measures of cognitive dysfunction, the clinical efficacy and safety of RO4917383 in patients with schizophrenia and schizoaffective disorder. Patients will be randomized to receive either RO4917383 (10mg daily orally) or placebo for 6 weeks, in addition to their stable antipsychotic medication. Anticipated time on study treatment is 6 weeks.
