Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 to 65 with DSM-5 major depressive disorder without psychotic features who report excessive daytime sleepiness, can comply with study visits, and do not have other significant medical or sleep disorders are the intended participants.
✕Probably not a fit
People with other clinically significant medical, behavioral, or sleep disorders such as obstructive sleep apnea or narcolepsy, or those with psychotic features, are excluded and unlikely to benefit from this specific approach.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This Phase 3, double-blind, placebo-controlled, multicenter randomized withdrawal trial uses an open-label solriamfetol lead-in followed by a randomized withdrawal period. Eligible adults with MDD and excessive daytime sleepiness receive open-label solriamfetol (150 mg) and those who achieve a clinical response are randomized 1:1 to continue solriamfetol or switch to placebo. Participants are monitored during the double-blind period for relapse of depressive symptoms and for durability of wakefulness and safety effects. The protocol includes screening and follow-up periods and is conducted at clinical research sites in California.
Why it matters
Potential benefit: If successful, solriamfetol could lessen daytime sleepiness and help maintain improvement in people with MDD who experience EDS.
How similar studies have gone: Solriamfetol is approved for treating excessive daytime sleepiness in narcolepsy and obstructive sleep apnea, but using it specifically for EDS linked to major depressive disorder is relatively novel with limited randomized evidence to date.
