Official title
A Multicenter, Double-blind, Placebo-controlled, Randomized Withdrawal Study of Solriamfetol in Subjects With Major Depressive Disorder With Excessive Daytime Sleepiness Symptoms
Overview
CLARITY (Clinical Assessment of Response in the Treatment of Depression with Daytime Sleepiness Using Solriamfetol) is a Phase 3, double-blind, placebo-controlled, multicenter randomized withdrawal trial in patients with major depressive disorder (MDD) with excessive daytime sleepiness (EDS) symptoms consisting of an open-label solriamfetol treatment period and a randomized, double-blind treatment period.
Detailed description
The study will consist of a screening period, an open label solriamfetol treatment period, a double-blind randomized withdrawal period, and a follow-up period. Eligible subjects will be treated with open-label solriamfetol and monitored for clinical response. Subjects achieving clinical response will be randomized into the double-blind randomized withdrawal period in a 1:1 ratio to either continued treatment with solriamfetol or to switch to placebo, for the remainder of the double-blind period or until they experience relapse of depressive symptoms.
Interventions
