Valby, Denmark and Tokyo, Japan, 13 April 2021 - H. Lundbeck A/S (Lundbeck) and Otsuka Pharmaceutical Co., Ltd. (Otsuka) announce the decision to continue the recruitment of patients in the phase III clinical trial of brexpiprazole in the treatment of agitation in patients with dementia of the Alzheimer's type (NCT03548584). The decision to continue the trial is based on the results of an independent interim analysis, supporting to progress the trial to the planned full enrollment of 330 patients.
The continuation of the study enables Lundbeck and Otsuka to further explore the efficacy of brexpiprazole to address the high medical need in patients suffering from agitation in Alzheimer's type dementia. Completion of the trial is expected in the first half of 2022.
About the study
Trial 331-14-213 (NCT03548584; Trial 213) was designed to assess the safety, tolerability and efficacy of brexpiprazole in the treatment of patients with agitation in Alzheimer's dementia. The trial consists of a continuous 12-week double-blind treatment period with a 30-day follow-up. The trial population is planned to include 330 male and female patients, aged 55-90 years, with a diagnosis of probable Alzheimer's disease.
The primary outcome is change in the Cohen-Mansfield Agitation Inventory (CMAI) Total score. The key secondary outcome measure is change in the Clinical Global Impression - Severity of Illness (CGI-S) score, as related to symptoms of agitation. Participating countries include Bulgaria, Hungary, Serbia, Slovakia, Spain, Ukraine and the U.S. Approximately half of the patients in the trial are living at home and the rest are institutionalized.
As agreed with the U.S. Food and Drug Administration (FDA), an interim analysis conducted by an independent Data Monitoring Committee was planned to assess both efficacy and futility, in accordance to pre-specified criteria, when 255 subjects had completed the trial.
Rexulti/Rxulti (brexpiprazole) is approved as an adjunctive therapy for the treatment of adults with major depressive disorder and as a treatment for adults with schizophrenia in markets such as the U.S. and Canada. In Europe and Japan, the product is approved for schizophrenia. In addition, brexpiprazole has been approved in over 20 other countries and regions across the world. Brexpiprazole is distributed and marketed under the brand name Rexulti[®]. In Europe, brexpiprazole is distributed and marketed under the brand name Rxulti[®].
Brexpiprazole was discovered by Otsuka and is being co-developed by Otsuka and Lundbeck. The mechanism of action for brexpiprazole in the adjunctive treatment of major depressive disorder or schizophrenia is not fully understood. However, the efficacy of brexpiprazole may be mediated through a combination of partial agonist activity at serotonin 5-HT\1A\ and dopamine D\2\ receptors, and antagonist activity at serotonin 5-HT\2A\ receptors. Brexpiprazole exhibits high affinity (sub-nanomolar) for these receptors as well as for noradrenaline alpha\1B/2C\ receptors.
