Sept 21 (Reuters) - Johnson & Johnson JNJ.N said on Monday its experimental use of Caplyta for bipolar mania met the main goal of a late-stage study, bringing the drug a step closer to expanding beyond its currently approved uses.
J&J gained Caplyta through its $14.6 billion acquisition of Intra-Cellular Therapies last year to bolster its neuroscience business.

Caplyta significantly reduced symptoms of bipolar mania compared with placebo in the late-stage trial, meeting the study's main goal, J&J said.
Symptoms of mania can include grandiosity, decreased need for sleep, racing thoughts, distractibility, and risk-taking behavior. 
Patients showed improvement as early as three days after starting treatment with the drug, with benefits maintained through the study's three-week duration, according to the company.
The study also met a key secondary goal measuring overall severity of illness, J&J said.
About 46% of patients treated with Caplyta achieved a clinical response, compared with about 21% of patients who received placebo, the company said.
The trial evaluated a once-daily 42-milligram dose of Caplyta in adults experiencing manic episodes associated with bipolar I disorder.
J&J's Caplyta is already approved in the United States for depressive episodes associated with bipolar I and bipolar II disorder and schizophrenia.
Bipolar disorder affects an estimated 37 million people worldwide. Mania, a defining feature of bipolar I disorder, is marked by unusually elevated or irritable mood and increased energy or activity levels that often occur alongside depressive episodes, according to J&J.
