Valby, Denmark and Tokyo, Japan, 2014-01-24 08:16 CET (GLOBE NEWSWIRE) --  

Valby, Denmark and Tokyo, Japan, 24 January 2014 - H. Lundbeck A/S (Lundbeck) and Otsuka Pharmaceutical Co., Ltd. (Otsuka) today announced that the first top-line phase III trial data on the investigational compound brexpiprazole will be presented at the 22nd European Psychiatry Association Congress (EPA) in Munich, Germany on 2 March, 2014.

Data from a completed phase III, randomized, placebo-controlled study investigating the effect of brexpiprazole as adjunctive therapy to antidepressant therapy in patients with major depressive disorder (MDD) will be presented. Overall, brexpiprazole demonstrated efficacy and was well tolerated as adjunctive treatment for MDD patients with an inadequate response to antidepressant treatment.

At the EPA congress, highlighted data on brexpiprazole as adjunctive therapy to anti-depressant therapy in MDD will include:

  • Statistically significant improvements in mean MADRS total score for patients receiving adjunctive brexpiprazole compared with placebo. MADRS (Montgomery–Åsberg Depression Rating Scale) is a commonly used scale to assess the range of symptoms in patients with major depression
  • A statistically significant advantage over placebo on all secondary endpoints.
  • Most common (>5% and more than twice placebo) adverse events reported in the patients receiving adjunctive brexpiprazole included weight gain and akathisia (inner restlessness)
  • Over 90% of patients completed the randomized phase of the trial
  • Additional information provided in the poster presentation at the EPA congress will be publicly disclosed at that time 

Lundbeck and Otsuka are running an extensive development program for brexpiprazole. Three additional studies in depression and schizophrenia will conclude in the first half of 2014. The outcome of these studies will allow us to determine if brexpiperazole can be filed in the US in 2014.

About brexpiprazole (OPC-34712)

Brexpiprazole is a novel investigational psychotherapeutic compound discovered by Otsuka and under co-development with Lundbeck. Brexpiprazole is a serotonin-dopamine activity modulator (SDAM) acting as a partial agonist at 5-HT1A and dopamine D2 receptors at similar potency, and an antagonist at 5-HT2A and noradrenaline alpha1B receptors. It is hypothesized to provide improved efficacy and tolerability over established adjunctive treatments for MDD.

Brexpiprazole is in phase III clinical testing for adjunctive treatment of MDD and for schizophrenia.  Additional phase III clinical trials include patients with agitation associated with dementia of the Alzheimer’s type, and adult patients with post-traumatic stress disorder.
