Buprenorphine/samidorphan (developmental code name ALKS-5461) is a combination formulation of buprenorphine and samidorphan which is under development as an add on to antidepressants in treatment-resistant depression (TRD).[2]
ALKS-5461 failed to meet its primary efficacy endpoints in two trials from 2016.[3] On the basis of a third study that did meet its primary endpoints, Alkermes initiated a rolling New Drug Application with the FDA.[4]
In November 2018, an FDA panel voted against recommending approval, finding that evidence was insufficient.[5] As such, approval of the medication was rejected in 2019.[6] It is a κ-opioid receptor (KOR) antagonist and is being developed by Alkermes.
