TOKYO & COPENHAGEN, Denmark--(BUSINESS WIRE)--Dec 21, 2012 - Otsuka Pharmaceutical Co., Ltd. (Otsuka) and H. Lundbeck A/S (Lundbeck) today announced the European Medicines Agency's (EMA) acceptance of the submission of a marketing authorisation application (MAA) for the approval of aripiprazole depot formulation. The application of aripiprazole depot formulation is for the maintenance treatment of adult patients with schizophrenia.
"Our efforts to bring the aripiprazole depot formulation to market demonstrate our long-term commitment to discover, develop and champion treatments for the most challenging psychiatric diseases," said William H. Carson, M.D., President and CEO, Otsuka Pharmaceutical Development & Commercialization, Inc. "If approved, more patients with schizophrenia will have access to the efficacy and safety profile of aripiprazole in a once-monthly formulation."
"Long-acting therapies are moving to the forefront of treatment for psychiatric disorders, and I am very excited that we now also have submitted this product in Europe," says Executive Vice President Anders Gersel Pedersen, Head of Research & Development at Lundbeck, and continues: "If approved, aripiprazole depot formulation will offer the clinical properties of oral aripiprazole, including its safety and efficacy profile, in a form that is suited to patients who may have difficulties consistently taking their medication."
Aripiprazole depot formulation is the first dopamine D2 partial agonist submitted in Europe as a once-monthly injection. If approved, it will be a new treatment option to address the need for relapse prevention in patients with schizophrenia, a chronic and debilitating disease.
Results from the first clinical trial of aripiprazole depot formulation were presented in four poster presentations at the 2012 American Psychiatric Association (APA) Annual Meeting in May 2012 and have subsequently been published in the Journal of Clinical Psychiatry (Kane et al J Clin Psych, 2012). In December 2012, data from the second pivotal trial were presented at the 51st Annual Meeting at the American College of Neuropsychopharmacology (ACNP) in Hollywood, Florida.
On 11 November 2011, Otsuka and Lundbeck announced an alliance to collaborate on the development and commercialisation of up to five early and late stage compounds in development. The two companies will co-commercialise aripiprazole depot formulation in the U.S. and will collaborate on the development and commercialisation of aripiprazole depot formulation in other markets worldwide. Aripiprazole depot formulation remains under review by the U.S. Food and Drug Administration (FDA).
About schizophrenia and disease relapse
Schizophrenia is a disease characterized by a distortion in the process of thinking and of emotional responsiveness. It most commonly manifests as hallucinations, paranoid or bizarre delusions, or disorganized speech and thinking, and is accompanied by significant social or occupational dysfunction. Onset of symptoms typically occurs in young adulthood, and the condition is chronic, often requiring life-long treatment to mitigate symptoms. It has been estimated that schizophrenia affects approximately 1% of the adult population in the U.S. and Europe, and approximately 24 million people worldwide1,2. In the U.S., there are approximately 2.4 million adults with schizophrenia, prevalent equally in both genders3,4. While there is no cure for the disease, symptoms and risk of relapse can be managed in most patients with appropriate antipsychotic treatment. However, when the disease is not managed, patients are at increased risk of disease relapse, which can cause the re-emergence or worsening of psychotic symptoms.
Relapses can occur during the natural course of schizophrenia5, but the major driver of recurrent episodes is medication non-adherence6,7, which may be as high as 50%. There are many reasons patients stop taking their medication and they include: poor insight about their illness, side effects from their current treatment, complicated medication regimens or lack of support from their family.
Recurrent relapses can result in function decline that may never return to pre-morbid levels6,8,9. The goals of long-term therapy in schizophrenia are therefor to prevent relapse, and to reduce the severity of side effects and residual symptoms10,11.
About aripiprazole depot formulation
Aripiprazole depot formulation for extended-release injectable suspension, an intramuscular (IM) depot formulation of aripiprazole, is a sterile lyophilized powder that, when reconstituted with sterile water for injection, forms an injectable suspension that can be administered monthly.
After an initial injection of aripiprazole depot formulation along with an overlapping 14-day dosing of oral antipsychotic treatment, subsequent injections of aripiprazole depot formulation provide uninterrupted medication coverage for a month. Depot formulations of antipsychotic agents provide patients with stable concentrations of active drug that remain at a therapeutic range for an extended period of time and also allow psychiatrists to know when a patient does not return for a scheduled injection12,13.
