MARLBOROUGH, Mass.--(BUSINESS WIRE)--Sunovion Pharmaceuticals Inc. (Sunovion) today announced the results of the PEARL 3 study, the third phase 3 worldwide clinical trial of Latuda® (lurasidone HCl) tablets, a once-daily atypical antipsychotic agent recently approved by the U.S. Food and Drug Administration (FDA) for the treatment of patients with schizophrenia. In this six-week, placebo-controlled trial, both fixed doses of LATUDA 80 and 160 mg once-daily, demonstrated statistically significant improvement in symptoms of schizophrenia versus placebo across both primary and secondary efficacy measures. LATUDA was also well tolerated with a relatively low discontinuation rate. The LATUDA 160 mg/day dose has not been reviewed or approved by FDA. The study was presented today at the American College of Neuropsychopharmacology (ACNP) 49th Annual Meeting in Miami, Florida.
