Recruiting studies
- NCT01406691RecruitingPhase 4
Light flashes for delayed sleep phase disorder
This trial tests whether timed light flashes can help people whose sleep schedule is consistently delayed (they fall asleep and wake up much later than desired). If you’re still in high school and your main issue is this delayed sleep pattern, you may be able to join.
Palo Alto, CaliforniaAges 15–19 - NCT07424703Recruiting
Bright Light Therapy for Teen Scoliosis
This study tests whether using a special bright light device at certain times of day can help improve spine curvature in teenagers with scoliosis. It is for adolescents who are night owls and have mild to moderate scoliosis.
Zhejiang, ZhejiangAges 10–15 - NCT06139861Recruiting
Better Sleep Study
This study tests a program to help you sleep better. It is for people who are generally healthy and do not have serious medical or mental health conditions.
Los Angeles, CaliforniaAges 12–18 - NCT05177055Recruiting
Sleep program for delayed sleep timing with mental health symptoms
This study offers a sleep-focused program to people whose sleep schedule is significantly shifted later than desired (delayed sleep phase disorder) along with moderate to severe mental health symptoms. It aims to see if treatment for the sleep problem can help in people already getting psychiatric care.
Bergen, TertnesAges 18–80 - NCT06471374Recruiting
Circadian rhythm in delayed sleep-wake phase disorder
This study looks at how your body's internal clock works in people with delayed sleep-wake phase disorder, especially those living at high altitudes. It aims to understand the causes of this sleep problem and may help find better treatments.
Boulder, ColoradoAges 16–40 - NCT06874855RecruitingPhase 4
Study of sleep medication for delayed sleep phase syndrome
This trial tests whether a sleep medication called lemborexant can help people with delayed sleep phase syndrome fall asleep earlier. It may improve sleep timing and reduce the impact on daily life.
San Francisco, CaliforniaAges 18 years+ - NCT06949644Recruiting
Pupil light reflex test in delayed sleep phase disorder
This study uses a simple camera test (pupillometry) to measure how your pupils react to light, which may help understand delayed sleep-wake phase disorder. It could be a way to better diagnose or treat this condition.
Chicago, IllinoisAges 16 years+ - NCT06226025RecruitingPhase 2
Melatonin for Bipolar Disorder in Night Owls

Tasimelteon for delayed sleep phase disorder with genetic variant
This study tests a new sleep medication called tasimelteon compared to a placebo (inactive treatment) for people with a specific sleep disorder linked to a genetic change in the body's internal clock. If you have Delayed Sleep-Wake Phase Disorder and carry the CRY1Δ11 variant, this trial may help improve your sleep timing.
