Recruiting studies
- NCT06535178Recruiting
Sleep and heart health in fibromyalgia
This study looks at how sleep affects heart health in people with fibromyalgia (a condition causing widespread pain). Researchers will test if improving sleep can help your heart work better.
Portland, OregonAges 18–50 - NCT05977712Recruiting
Circadian rhythm factors in people with memory clinic concerns
This study looks at how daily body-clock timing (circadian rhythm) and other factors may relate to memory and thinking symptoms in memory clinic patients. You may be asked to wear a small device for about 9 days to track your daily patterns.
Paris, FranceAges 18 years+ - NCT05829044Recruiting
How light exposure affects sleep and body clock by sex and age
This study looks at how non-visual light (light that isn’t just for seeing) affects your sleep timing and circadian rhythms, and whether the effects differ by sex and age. It may help researchers design better light-based or sleep-support strategies in the future.
Boston, MassachusettsAges 18–85 - NCT05336084Recruiting
Study how sleep timing affects mood and thinking in teens
This study looks at how your body clock and sleep “pressure” affect reward feelings and thinking control. It may help researchers understand teen sleep patterns and how they connect to brain and behavior.
Pittsburgh, PennsylvaniaAges 13–18 - NCT04893226Recruiting
Time-restricted eating for postmenopausal metabolic risk
This trial studies whether limiting when you eat each day can improve blood sugar and other health markers in postmenopausal women with prediabetes or metabolic risk factors. It may help your body’s metabolism if your sleep and daily routine can stay fairly consistent.
Lexington, KentuckyAges 45–65 - NCT07821060Enrolling by invitation
Diet and meal timing for attention deficit hyperactivity disorder
This study looks at whether changing when you eat and improving your gut health (microbiome) can help manage attention deficit hyperactivity disorder (ADHD). It compares different diet and eating schedules to see if they improve ADHD symptoms.
Paterna, ValenciaAges 18–65

Common questions
- Are there clinical trials for circadian rhythm disorders?
- Yes. Clin2 currently lists 54 recruiting circadian rhythm disorders studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a circadian rhythm disorders trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a circadian rhythm disorders trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
