Icalcaprant [1] (developmental code name CVL-354) is an opioid antagonist which is under development for the treatment of major depressive disorder and substance-related disorders. [2] [3] It is taken by mouth. [2]
It acts as a selective antagonist of the κ-opioid receptor. [2] [3] The drug is also more weakly an antagonist of the μ-opioid receptor, with about 31-fold lower affinity and 27-fold lower inhibitory potency at the μ-opioid receptor relative to the κ-opioid receptor. [3]
It was originated by Pfizer and is under development by Cerevel Therapeutics (a subsidiary of AbbVie). [2] [4] As of September 2022, icalcaprant is in phase 1 clinical trials for major depressive disorder and is in the preclincal stage of development for substance-related disorders. [2]
