Recruiting studies
- NCT06645093Enrolling by invitation
Intermittent fasting during chemo for lymphoma
This study tests whether intermittent fasting is safe and doable for people with lymphoma who are getting standard chemotherapy (R-CHOP or ABVD). It aims to see if adding fasting periods can help reduce side effects.
Oslo, OsloAges 18–80 - NCT07111065RecruitingPhase 2
Fatty Acid Supplement for Dermatomyositis
This study tests whether taking a fatty acid supplement (omega-3) for 6 months can help reduce disease activity in people with dermatomyositis. Participants will also receive dietary coaching and have regular check-ups at the NIH to monitor their progress.
Bethesda, MarylandAges 18–60 - NCT06701929Recruiting
Fasting time and recovery after c-section
This trial looks at how long you fast (go without food or drink) before a planned c-section and whether that affects how well you feel after the surgery. It aims to find the best fasting time to improve your recovery.
Montreal, QuebecAges Any age - NCT06543615Enrolling by invitation
Ultrasound stomach check before surgery in sleeve gastrectomy patients
This study uses ultrasound to measure how much stomach content remains after fasting in people who have had sleeve gastrectomy surgery. It aims to understand if the standard 8-hour fasting period is enough for this group before other surgeries.
Cairo, Cairo GovernorateAges 21–45 - NCT06123988Recruiting
Fasting and exercise for breast cancer fatigue
This study tests whether changing your eating and exercise habits can help reduce fatigue and improve other symptoms. Participants will either extend their overnight fasting period, increase their exercise, or both, while continuing their standard breast cancer treatment.
Phoenix, ArizonaAges 18 years+ - NCT06386887Recruiting
Fasting During Chemotherapy for Ovarian Cancer
This trial tests whether adding periods of fasting to standard chemotherapy before surgery helps people with advanced ovarian cancer. It is for those receiving platinum-based chemo for the first time or after recurrence.
Cleveland, OhioAges 18 years+ - NCT06327997RecruitingEarly Phase 1
Fast CAR-T cells for advanced solid tumors
This trial tests a new type of 'fast CAR-T' cell therapy for people with advanced solid tumors that have not been helped by standard treatments. CAR-T cells are a kind of immune cell that is reprogrammed to attack cancer cells that carry certain markers called mesothelin, MUC1, and PD-L1.
Shanghai, Shanghai MunicipalityAges 18–70 - 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 - NCT06249256RecruitingEarly Phase 1
Fast CAR T cells for advanced solid tumors
This trial tests a new type of CAR-T cell therapy called Fast CAR T cells for people with advanced solid tumors. It is designed for patients whose tumors have certain markers (mesothelin and PD-L1) and who have not responded to or cannot tolerate standard treatments.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT07639372Recruiting
Fast vs. slow-dissolving stitches for large surgical wounds
This study compares two types of stitches that dissolve at different speeds in people having skin surgery with larger cuts. Researchers want to see which type heals better and causes less tension on the wound.
Lanzhou, GansuAges Any age - NCT06134258Recruiting
How fasting affects metabolism in healthy young adults
This study looks at how a period of fasting changes the amount of energy your body burns at rest. It may help explain why fasting can affect weight and health.
BaselAges 18–40 - NCT07672093Recruiting
Dry needling for forearm muscle knots
This study tests whether inserting a thin needle (dry needling) into a tight muscle knot in your forearm can help release it without causing pain. It's for healthy adults who have a non-painful knot in their dominant arm.
Reus, TarragonaAges 18–40 - NCT07498361Recruiting
Comparing absorbable stitches in wisdom tooth removal
This trial compares two types of dissolving stitches (sutures) used after wisdom tooth surgery to see which works better. It may help your mouth heal faster with fewer problems.
Padua, PaduaAges 18 years+ - NCT06901050Recruiting
A study of FAST HUGS care for ICU patients with low oxygen
This trial tests a special care bundle called 'FAST HUGS' to see if it helps people in the ICU with low oxygen levels get better sooner. It focuses on patients in the Chest Intensive Care Unit who have trouble getting enough oxygen.
ErzurumAges 18–100 - NCT07336160Recruiting
Nutrition before knee replacement surgery
This trial studies a special nutrition plan before knee replacement surgery to see if it helps recovery. Participants follow enhanced recovery guidelines for eating and drinking before their operation.
Istanbul, IstanbulAges 18 years+ - NCT06900257Enrolling by invitation
Fetal heart function in fasting pregnant women
This study looks at how babies' hearts work when mothers have been fasting for at least 10 days. It may help understand if fasting affects the baby's heart health.
SanliurfaAges 18–50 - NCT07288281Recruiting
Preoperative Clear Fluid Fasting in Liver Transplant
This trial looks at how long before surgery patients waiting for a liver transplant can drink clear fluids, like water. The goal is to find a safer or more comfortable fasting time.
Warsaw, WarszawaAges 18 years+ - NCT07006142Recruiting
Fasting time and stomach volume for GLP-1 patients
This trial studies how a longer fasting period affects stomach contents in people taking GLP-1 receptor agonists (a type of diabetes or weight-loss drug). It helps doctors understand if extra fasting time is needed before an upper endoscopy (a camera test for the stomach).
Rochester, MinnesotaAges 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+ - NCT07680452Recruiting
High-fiber diet and short-term fasting for melanoma patients on immunotherapy

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.
