Nelotanserin

Drug Candidate for Neurological Diseases

Nelotanserin is a potent and selective inverse agonist of the 5-HT2A receptor that has been implicated in the pathophysiology underlying psychosis. Nelotanserin was discovered and developed by Arena, and completed Phase 1 trials in healthy volunteers and Phase 2 trials in subjects with insomnia before development was discontinued for that indication.
