Following single doses of lemborexant 2.5 to 75 mg, geometric mean C max and AUC 0-24h increased slightly less than in proportion to dose. The extent of accumulation of lemborexant at steady-state is 1.5- to 3-fold across this dose range.

AbsorptionThe time to peak concentration (t max ) of lemborexant is approximately 1 to 3 hours. Effect of Food Lemborexant C max decreased by 23%, AUC 0-inf increased by 18%, and t max was delayed by 2 hours following administration of a high-fat and high-calo...

14.1 Controlled Clinical Studies DAYVIGO was evaluated in two clinical trials in patients with insomnia characterized by difficulties with sleep onset and/or sleep maintenance (

Study 1NCT02952820 and

Study 2NCT02783729). Study 1 was a 6-month, randomized, double-blind, placebo-controlled, multi-center trial in adult patients age 18 or older who met DSM-5 criteria for insomnia disorder. Patients were randomized to placebo (n=325), DAYVIGO 5 mg (n=323), or DAYVIGO 10 mg (n=323) once nightly. The primary efficacy endpoint was the mean change from baseline to end of treatment at 6 months for l...
