Otsuka and Lundbeck's Brexpiprazole Demonstrates Statistically Significant Effects in New Phase III Studies in Adult Patients with Schizophrenia Presented at the American College of Neuropsychopharmacology Annual MeetingOtsuka Pharmaceutical Co., Ltd. (Otsuka) and H. Lundbeck A/S (Lundbeck) today announced the presentation of Phase III study results evaluating the effects of an investigational compound, brexpiprazole, as monotherapy in adult patients with schizophrenia at the 53rd Annual Meeting of the American College of Neuropsychopharmacology (ACNP) in Phoenix, Arizona. The data were shared in two poster presentations, "A Multicenter, Randomized, Controlled, Phase III Trial of Fixed-dose Brexpiprazole for the Treatment of Adults with Acute Schizophrenia" and "Brexpiprazole for the Treatment of Acute Schizophrenia: A Randomized, Controlled Trial." "Schizophrenia is a debilitating condition and patients often struggle to maintain a treatment regimen for multiple reasons, including lack of efficacy and undesired side effects," said Dr. Christoph U. Correll, Professor of Psychiatry, Hofstra North Shore LIJ School of Medicine and Medical Director, Recognition and Prevention Program (RAP), The Zucker Hillside Hospital, both in New York, and lead author of one of the study reports. "Therefore, additional treatment options are needed. The signals of efficacy, together with the favorable side effect profile observed in this study, support the use of brexpiprazole in this patient population." Schizophrenia Study Results The poster, "Brexpiprazole for the Treatment of Acute Schizophrenia: A Randomized, Controlled Trial," (NCT01396421) evaluated the efficacy and tolerability of brexpiprazole in adult patients with acute schizophrenia. The pivotal Phase III trial randomized 636 patients with acute schizophrenia to fixed doses of brexpiprazole (0.25mg, 2mg or 4mg) or placebo (randomized 1:2:2:2) respectively for 6 weeks. The results indicated:
The poster, "A Multicenter, Randomized, Controlled, Phase III Trial of Fixed-dose Brexpiprazole for the Treatment of Adults with Acute Schizophrenia," (NCT01393613) showcased results from a pivotal Phase III trial that randomized 674 patients with acute schizophrenia to fixed doss of brexpiprazole (1mg, 2mg, 4mg) or placebo (2:3:3:3) respectively for 6 weeks. The results indicated:
"We and Lundbeck are proud to present these data results for the first time as a critical part of the clinical program supporting the safety and efficacy of brexpiprazole in adults with schizophrenia," said William Carson, MD, CEO, Otsuka Pharmaceutical Development & Commercialization, Inc. "It is our hope that brexpiprazole will offer schizophrenia patients another treatment option to manage symptoms while living with this disease." "Schizophrenia is a complicated disease experienced by approximately 2.4 million adults in the U.S., and having more treatment options is critical to addressing unmet needs. We still lack a truly effective and predictable path toward treatment," said Anders Gersel Pedersen, MD, EVP and head of R&D in Lundbeck. "While advances have been made, we believe brexpiprazole can be a strong new treatment choice for these patients." Otsuka and Lundbeck also presented results from two Phase III studies evaluating the effect of brexpiprazole as adjunctive treatment to antidepressant therapy (ADT) in patients with major depressive disorder (MDD) at ACNP. The data were shared in a poster presentation, "Efficacy and Safety of Adjunctive Brexpiprazole (OPC-34712) in Major Depressive Disorder: Results of Two Pivotal Clinical Studies." About Brexpiprazole (OPC-34712) Brexpiprazole is a novel investigational psychotropic compound discovered by Otsuka and under co-development with Lundbeck. Brexpiprazole is a serotonin-dopamine activity modulator (SDAM) that acts as a partial agonist at 5-HT1A and dopamine D2 receptors, and an antagonist at 5-HT2A and noradrenaline alpha1B/2C receptors, all with similar high potency (< 1 nM). A New Drug Application for brexpiprazole has been filed with the U.S. Food and Drug Administration (FDA) and the PDUFA date is in July 2015. About Otsuka Pharmaceutical Co., Ltd.
