Clinical Trial Summary

The primary objective of this study was to assess time to discontinuation due to lack of tolerability among patients with schizophrenia receiving LY2140023, given orally twice daily for 24 weeks, versus those on atypical antipsychotic standard-of-care (SOC) treatment. Lack of tolerability was defined as discontinuation due to adverse events (AEs).

Patients who completed the active treatment phase were eligible to continue to an optional 28 weeks of treatment extension phase. This extension phase assessed key safety and efficacy measures.

Description:

A Phase 2, multicenter, randomized, parallel, open-label study comparing the long-term safety and tolerability of LY2140023 with atypical antipsychotic agents considered to be the current SOC for patients with schizophrenia. The study included a 24-week active treatment phase and an optional 28-week active treatment extension phase.

The time to discontinuation due to AEs during Study Period III (24-week active treatment phase) was compared between LY2140023 and standard of care using the log-rank test from the Kaplan-Meier survival analysis. Patients who completed Study Period III or who discontinued for a reason other than AEs were considered as censored observations.

Secondary objectives were assessed during both Study Period III [Active Treatment Phase] and Study Period IV [Active Treatment Extension Phase]) except for treatment-emergent adverse events (TEAEs), extrapyramidal symptoms (EPS), electroencephalograms (EEGs), electrocardiograms (ECGs) (analysis for Study Period III only) (indicated in "Time Frame" in "Results" section)
