Positive topline results have been announced for ALKS 5461, a once-daily, oral investigational drug for the adjunctive treatment of major depressive disorder (MDD) in patients with an inadequate response to standard antidepressant therapies. 

In the study (FORWARD-5), ALKS 5461 2mg/2mg met the prespecified primary endpoint of significantly reducing depression scores compared to placebo, as measured by 6-item Montgomery–Åsberg Depression Rating Scale (MADRS-6) scores (P=0.018). ALKS 5461 2mg/2mg also demonstrated statistically significant reductions in 10-item MADRS (MADRS-10) scores compared to placebo (P=0.026). The 1mg/1mg dose of ALKS 5461 showed improvement in depressive symptoms in the study, but did not separate significantly from placebo.

ALKS 5461 is an investigational, once-daily oral medicine that acts as a balanced neuromodulator in the brain and represents a novel mechanism of action for treating MDD. ALKS 5461 consists of samidorphan and buprenorphine, and is designed to rebalance brain function that is dysregulated in the state of depression.

In October 2013, the FDA granted Fast Track status for ALKS 5461 for the adjunctive treatment of MDD in patients with an inadequate response to standard antidepressant therapies. Based on these results, along with the substantial data collected to date on the efficacy and safety of ALKS 5461 for the treatment of MDD, Alkermes plans to request a meeting with the U.S. Food and Drug Administration's (FDA) Division of Psychiatric Products to discuss the filing strategy for this Fast Track designated medicine.
