Medical uses
Acoltremon is indicated for the treatment of the signs and symptoms of dry eye disease.Pharmacology
Acoltremon acts as a potent and selective activator of the TRPM8 calcium channel, which is responsible for the sensation of coldness produced by menthol. It is slightly less potent as a TRPM8 activator compared to icilin, but is a much more selective TRPM8 ligand when compared to menthol.History
The US Food and Drug Administration approved acoltremon based on evidence from two clinical trials of 931 participants with dry eye disease. The trials were conducted at 46 sites in the United States. Two additional studies: COMET-1 and COMET-4 were included in the evaluation of safety benefit of acoltremon. The number of participants representing efficacy findings may differ from the number of participants representing safety findings due to different pools of study participants analyzed for efficacy and safety. Both COMET-2 and COMET-3 are phase III, multi-center, vehicle-controlled, double-masked, randomized studies whose primary endpoint was proportion of participants with ≥10 mm increase from baseline in unanesthetized Schirmer Score on day 14. COMET-1 was a phase IIb multi-center, vehicle-controlled, double-masked, randomized study conducted at 15 sites in the United States which randomized 369 participants with a history of dry eye disease. COMET-4 was a multi-center, vehicle-controlled, double-masked, randomized study conducted at approximately 10 sites in the United States which enrolled 275 participants with a history of dry eye disease. Study COMET-2 and COMET-3 have a similar design. Each study is a multi-center, randomized, double-masked, vehicle-controlled phase III study. The primary objective of these studies was to evaluate the safety and efficacy of acoltremon compared to vehicle. Participants 30 years and older with a history of artificial tear use for dry eye disease were qualified based on signs and symptoms of dry eye disease at screening, and were requalified at baseline following a 14-day vehicle run-in. COMET 2 enrolled 465 participants at 23 study sites, whereas COMET-3 enrolled 466 participants at 23 sites.Society and culture
