Vanda Pharmaceuticals Inc. received approval from the FDA for Fanapt (iloperidone) tablets for the acute treatment of manic or mixed episodes associated with bipolar I disorder in adults. Fanapt is an atypical antipsychotic agent that has been used for the acute treatment of patients with schizophrenia since its FDA approval
in 2009.
Bipolar disorder is a serious, highly prevalent psychiatric chronic condition affecting approximately 2.8% of the U.S. adult population, with 83% of them classified as severe. Bipolar disorder is a group of disorders that are characterized by periods of elevated mood alternating with periods of depressed mood. For the diagnosis of bipolar I disorder, people must have experienced one or more episodes of mania and most would have episodes of both mania and depression.
The marketing approval of Fanapt in bipolar I disorder with manic and mixed episodes significantly increases the commercial opportunity for Fanapt.
The approval was based on a pivotal study randomizing approximately 400 patients. The primary endpoint measured in Week 4 of treatment was assessed by the Young Mania Rating Scale (YMRS), a rating scale of clinical severity in the core symptoms of mania. At the end of the study, Fanapt treated patients showed a larger improvement than placebo treated patients, and this difference was highly statistically significant. YMRS was assessed at the end of Weeks 1, 2, 3 and 4. Statistically significant benefit in the Fanapt treated group over placebo was observed as early as the Week 2 assessment.
