Targeted therapy for slow-flow or fast-flow vascular malformations
This trial tests two targeted medicines for people with certain types of vascular malformations (abnormal blood vessels). If you have a slow-flow malformation, you may receive alpelisib; if you have a fast-flow malformation, you may receive mirdametinib. Genetic testing is needed to see if your malformation has a specific change that these drugs target.

Chicago, IllinoisAges 18 years+ - NCT06043843Recruiting
Video Education to Reduce Diabetes Risks During Ramadan
This study tests whether focused video education can help people with type 2 diabetes manage their blood sugar safely while fasting during Ramadan. You will receive extra teaching and support through video calls to reduce the risk of complications.
SingaporeAges 21–100 - NCT06093477Recruiting
Melatonin and recovery for teens after surgery
This study tests whether taking melatonin (a natural sleep hormone) after a major bone or joint surgery helps teens recover better. If you are 12-18 and having a surgery like scoliosis repair, you may be able to join.
Palo Alto, CaliforniaAges 12–18 - NCT06172283Recruiting
Intermittent fasting with hormone therapy for prostate cancer
This trial tests whether intermittent fasting (alternating between eating and not eating for certain periods) can help men with prostate cancer who are receiving hormone therapy (androgen deprivation therapy). It aims to see if fasting during treatment can reduce side effects or improve how well the therapy works.
Buffalo, New YorkAges 18 years+ - NCT07692646Recruiting
Fasting's effect on fat burning and energy in cells
This study looks at how fasting changes the way your body burns fat and how cells produce energy. If you are a healthy adult of normal weight or living with obesity, you may help researchers understand the effects of fasting on metabolism.
CopenhagenAges 18–40 - NCT06535815Recruiting
Cyclic daytime feeding with ketogenic nighttime fasting for ICU patients
This trial tests a special feeding schedule where ICU patients receive nutrition during the day and fast at night, which may help their recovery. It aims to see if this approach is safe and beneficial.
Cologne, North Rhine-WestphaliaAges 18 years+ - NCT06546033Recruiting
Intermittent fasting and Mediterranean diet for multiple sclerosis
This study tests whether a combination of intermittent fasting (eating only during certain hours) and a Mediterranean diet (rich in fruits, vegetables, whole grains, and healthy fats) can help improve symptoms in women with multiple sclerosis (MS). If you are a woman with MS and not in an active flare-up, this trial may offer a new way to manage your condition through diet.
Niğde, BorAges 18–65 - NCT06610162Recruiting
Metabolic responses to fasting and overfeeding in women
This study looks at how women's bodies burn energy (thermogenesis) when they fast or eat a lot. Researchers want to understand how these processes differ in premenopausal vs. postmenopausal women.
Aurora, ColoradoAges 18–65 - NCT06610565Recruiting
Fasting-mimicking diet for breast cancer side effects

Long Beach, CaliforniaAges 18 years+ - NCT06676813Recruiting
Fasting every other day for fatty liver disease
This study tests whether fasting every other day (alternate day fasting) can help reverse fatty liver disease (NASH/MASH) when added to standard medical care.

Common questions
- Are there clinical trials for fasting?
- Yes. Clin2 currently lists 209 recruiting fasting 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 fasting 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 fasting 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.
