BOSTON — Merck on Wednesday released new data from two pivotal Phase III efficacy trials for suvorexant, the investigational medicine Merck is developing for the treatment of insomnia.
Merck expects to file a new drug application to the Food and Drug Administration in 2012. If approved, suvorexant would be the first medicine approved in a new class of medicines, called orexin receptor antagonists, for use in patients with difficulty falling or staying asleep. Merck anticipates that suvorexant will be evaluated by the Controlled Substance Staff of the FDA.
