Recruiting studies
- 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+ - NCT06106477Recruiting
Intermittent fasting for women with early breast cancer
This trial studies whether a 14-hour night fast and 10-hour eating window can improve inflammation markers and quality of life in women with HR+/HER2- early breast cancer. You would start the fasting routine within three months of beginning hormone therapy.
Milwaukee, WisconsinAges 18 years+ - NCT06123988Recruiting
Fasting and exercise for advanced breast cancer
This study looks at whether fasting overnight and/or doing exercise can help improve fatigue and other quality-of-life measures in women with advanced hormone receptor positive breast cancer who are already taking a CDK4/6 inhibitor. Participation may involve following a fasting or exercise plan for a period of time.
Phoenix, ArizonaAges 18 years+ - 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 - NCT05983159RecruitingPhase 2
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.
Parkville, VictoriaAges 2 years+ - NCT05722873Recruiting
Study intermittent fasting and its effects on metabolism
This study looks at how intermittent fasting affects your body's “metabolism” (how you use food and manage blood sugar/fats). It may help researchers understand whether this eating pattern changes metabolic health in people at higher risk for type 2 diabetes.
Pittsburgh, PennsylvaniaAges 21–45 - NCT05263674RecruitingPhase 3
Faster ICU treatment for non-convulsive seizures in adults
This study compares two ways to stop non-convulsive seizures in the ICU. It tests whether fast sedation in intensive care works better than giving higher-dose anti-seizure medicine through a vein.
AarhusAges 18–120 - NCT05095714Recruiting
Fast MRI for close monitoring of high-risk liver cancer
This trial studies a faster MRI scan to help track early liver cancer in people who have cirrhosis and are considered high risk. It may improve how often and how well doctors can look for changes without using longer imaging sessions.
BondyAges 18 years+ - NCT03869996Recruiting
Fast-track recovery for knee replacement patients
This trial studies a faster recovery “fast-track” plan for people getting their first total knee replacement for arthritis. It may help by getting you back to movement and normal life sooner, while comparing outcomes against usual care.
BolognaAges 18–78 - NCT03615690Recruiting
Fasting-mimicking diet test for ulcerative colitis
This study tests whether a “fasting-mimicking diet” can improve mild to moderate ulcerative colitis. You would follow the study diet plan and be monitored to see if symptoms and disease activity change.
Palo Alto, CaliforniaAges 18–70 - NCT02969798Recruiting
Study of prediabetes with abnormal sugars and medicines
This study looks at adults with prediabetes—specifically abnormal fasting and/or 2-hour blood sugar tests—to see whether a treatment helps improve sugar control. You may also be compared with people who have normal blood sugar (the control group).
San Antonio, TexasAges 18–65 - NCT07714018Recruiting
Comparing two weight loss programs for kidney cancer patients
This study tests two different weight loss programs to see which one helps prevent kidney cancer from growing in people with small kidney masses who are under active surveillance. It may help by improving overall health and potentially slowing cancer progression.
Buffalo, New YorkAges 18 years+ - NCT04212520Recruiting
Using non-fasting cholesterol tests to predict heart events
This study looks at whether cholesterol levels measured without fasting can help predict future heart and blood vessel events in people living in the community. If you join, your non-fasting blood test results may be tracked to see how well they forecast cardiovascular risk.
Guangzhou, GuangdongAges 18 years+ - NCT02511158Recruiting
Knee ligament surgery study after ACL reconstruction
This study follows people who have a knee ligament tear and undergo surgery to rebuild the ligament. It may help doctors better understand recovery and outcomes after different surgical techniques.
ParisAges 7 years+ - NCT05799898Recruiting
Fast heart and vessel check for people on immune cancer drugs
This trial looks at a faster heart and blood-vessel assessment for people who are taking immune cancer drugs and have been referred because they might be having a heart-related side effect. It may help by speeding up evaluation and treatment decisions when symptoms raise concern.
ParisAges 18 years+ - NCT06439355Recruiting
Taste test for Parkinson's and Lewy body disease
This study measures how well people with Parkinson's or Lewy body disease can taste, using a special test. It aims to understand if taste problems are linked to these conditions and could help with earlier diagnosis.
DijonAges 18 years+ - NCT05458037Recruiting
Testing fast versus slow numbing during IUD or biopsy
This study compares two ways of applying a numbing tool (“tenaculum”) during an IUD insertion or an endometrial biopsy to see which one causes less pain. If you’re scheduled for one of these procedures, it may help improve how discomfort is managed.
Providence, Rhode IslandAges 18 years+ - NCT06345534Recruiting
Comparing two radiotherapy schedules for breast cancer
This trial compares two ways of giving radiation therapy after breast cancer surgery: FAST-FORWARD versus HAI5. It aims to find which schedule works best for people who need radiation to prevent the cancer from coming back.
GhentAges 18 years+ - NCT06302803Recruiting
Modified intermittent eating for weight loss trial
This trial tests a modified intermittent eating plan to help people with obesity lose weight and keep it off. It compares different eating schedules to see which works best for long-term weight control.
Guangzhou, GuangdongAges 18–75 - NCT07829237Recruiting
Fuel use during exercise in fit adults
This study looks at how your body uses fuel (carbohydrates and fats) during exercise, and whether that is different in males and females. If you are a healthy, active adult who regularly exercises, this research could help you understand your own body's energy systems.
Toronto, OntarioAges 18–35 - 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 - NCT06519032Recruiting

Common questions
- Are there clinical trials for fasting?
- Yes. Clin2 currently lists 207 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.
