Navacaprant

Navacaprant, a novel and selective kappa opioid receptor(KOR) antagonist, has no agonist properties implicated in opioid-related abuse.
Navacaprant is a potent KOR antagonist currently in clinical development for the treatment of neurobehavioral disorders, including Phase 3 clinical trials in adults with major depressive disorder. Navacaprant demonstrates high affinity and selectivity for the human KOR over the human MOR and DOR and exhibits reversible antagonist activity at KOR ex vivo and in vivo.
