Tasimelteon for delayed sleep phase disorder with genetic variant
Treatments studied
Part of Brain & nervous system, Mental health clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be between 18 and 75 years old.
- You must have a diagnosis of Delayed Sleep-Wake Phase Disorder (a condition where your body's sleep clock is shifted later than normal).
- You must have a specific genetic change called the CRY1Δ11 variant (this affects your internal body clock).

This study tests if the drug tasimelteon helps children with insomnia sleep better compared to a placebo (a pill with no medicine). It is for children aged 2 to 17 who have been diagnosed with insomnia that is not caused by another medicine.
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.
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.
This trial studies whether timed light exposure can help people who have trouble falling asleep. It aims to improve insomnia symptoms by testing a light-based approach while carefully measuring sleep patterns.
This trial tests whether giving melatonin at the right time can help people with bipolar disorder who are night owls improve their mood and sleep. You would take melatonin or a placebo each evening for a few weeks while tracking your symptoms on a phone app.
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.
