BUDAPEST, Hungary and DUBLIN, Jan. 20, 2015 /PRNewswire/ -- Gedeon Richter Plc. and Actavis plc (NYSE: ACT) today announced positive results from a Phase III trial evaluating the efficacy and safety of cariprazine in the prevention of relapse in patients with schizophrenia.

There were 101 patients randomized to cariprazine 3 to 9 mg per day and 99 randomized to placebo. The primary efficacy measure was time to first relapse during the double-blind period. There were 25 relapses (24.8%) in the cariprazine group versus 47 relapses (47.5%) in the placebo group. Treatment with cariprazine was associated with a 55% reduction in risk of relapse versus placebo (hazard ratio 0.45, 95% CI [0.28, 0.73] p=0.0010).
"We are pleased with the long-term efficacy results demonstrated in this trial. Cariprazine has the potential to provide patients suffering with schizophrenia a treatment that can reduce the risk of relapse associated with this serious illness," said David Nicholson, Actavis Senior Vice President, Global Brands R&D.
"We are encouraged by the positive top line results shown in this study, which are considered as a further milestone in the process of making this promising treatment option available for patients suffering from schizophrenia," added Dr. Istvan Greiner, Research Director of Gedeon Richter Plc.
About this Phase III Study
This 97 week study was a multi-national, multi-center, randomized, double-blind, placebo-controlled clinical trial in adult patients with schizophrenia. The study included a 20-week open-label phase where patients with schizophrenia were treated with cariprazine 3, 6 or 9 mg per day. Patients who responded and met the stabilization criteria during the open-label period were then randomized to continue their cariprazine dose (3, 6 or 9 mg per day) or switched to placebo for up to 72 weeks or until a relapse occurred. The primary endpoint was time to first symptom relapse during the double blind phase.
In the double-blind phase, there were no cariprazine adverse events >/=10%. Across the cariprazine treated group, the most common adverse events (incidence >/=5% and greater than placebo) were nasopharyngitis, tremor, extrapyramidal disorder, akathisia, back pain, and blood creatine phosphokinase increased.
About Cariprazine
Cariprazine, an investigational drug, is a potent dopamine D3/D2 receptor partial agonist atypical antipsychotic with preferential binding to D3 receptors for the treatment of patients with schizophrenia and for adult patients with manic or mixed episodes associated with bipolar I disorder. The safety and efficacy of cariprazine was studied in a clinical trial program of more than 2,700 adult patients. In addition, cariprazine is being investigated for the treatment of bipolar depression and as adjunctive treatment for major depressive disorder in adults. Cariprazine is protected by a composition-of-matter patent that expires in 2027.
