Study 402 positive results evaluating lumateperone as adjunctive therapy to lithium or valproate in the treatment of major depressive episodes associated with Bipolar I or Bipolar II disorder.-Intra-Cellular Therapies

Intra-Cellular Therapies, Inc. announced positive topline results from its Phase III clinical trial (Study 402) evaluating lumateperone as adjunctive therapy to lithium or valproate in the treatment of major depressive episodes associated with Bipolar I or Bipolar II disorder In Study 402, once daily lumateperone 42 mg met the primary endpoint for improvement in depression as measured by change from baseline versus placebo on the MADRS total score (p=0.0206; effect size = 0.27). Lumateperone 42 mg also met the key secondary endpoint, the CGI-BP-S Depression Score (p=0.0082; effect size = 0.31). The lower lumateperone dose, 28 mg, showed a trend for a dose-related improvement in symptoms of depression but the results did not reach statistical significance. Lumateperone demonstrated a favorable safety profile and was generally well-tolerated in the trial. The most commonly reported adverse events that were observed at a rate greater than or equal to 5% and at least twice the rate of placebo were somnolence, dizziness, and nausea. Rates of akathisia, restlessness, extrapyramidal symptoms, and changes in weight were similar to placebo. This trial, in conjunction with our previously reported positive Phase III monotherapy study, Study 404, forms the basis for our sNDA for the treatment of bipolar depression in patients with Bipolar I or II disorder as monotherapy and adjunctive therapy which we expect to submit to the FDA in late 2020 or early 2021.
