About Ropanicant
Ropanicant (SUVN-911) is a novel, selective nicotinic α4β2 receptor antagonist in development for MDD. The drug candidate has demonstrated strong efficacy in animal models of depression and may address key limitations of current treatments, including rapid onset of action, reduced sexual dysfunction, and enhanced cognitive function. The Phase-2a trial previously demonstrated a favorable safety profile and significant improvements in depressive symptoms as measured by the MADRS score.
