Delayed Sleep-Wake Phase Disorder (DSWPD) research hub

A multicenter, double-blind, randomized study to evaluate the effects of tasimelteon vs. placebo in participants with Delayed Sleep-Wake Phase Disorder (DSWPD)

This study looks at a medicine called tasimelteon for people with Delayed Sleep-Wake Phase Disorder. This condition makes it hard to fall asleep until very late at night. Researchers want to see if taking a daily capsule for 28 days helps people fall asleep earlier than a dummy pill.
