At a recent scientific meeting, Suresh Durgam of Intra-Cellular Therapies, Inc. reported on a study of lumateperone tosylate for the treatment of bipolar depression. Lumateperone tosylate is a mechanistically novel antipsychotic that has been approved by the US Food and Drug Administration for the treatment of schizophrenia.

In a double-blind, placebo-controlled study, the drug showed efficacy in bipolar I and II depression. In a 6-week study, 377 patients received either 42 mg/day of lumateperone or placebo, and 333 (87.4%) completed treatment. Lumateperone treatment significantly improved total scores on the Montgomery Asberg Depression Rating Scale (MADRS) compared with placebo. Item analysis revealed that 8 of 10 MADRS items improved significantly in comparison with placebo by day 29, and all items did by day 43. The largest effects were in reported sadness, apparent sadness, inner tension and reduced sleep. Durgam and colleagues concluded that lumateperone at a dose of 42mg improves a broad range of symptoms in bipolar I and bipolar II depression.
