AngersAges 18 years+ - NCT04661280RecruitingPhase 3
Donepezil compared with non-drug care for Alzheimer’s
This trial compares donepezil (a medicine for Alzheimer’s symptoms) against a non-drug treatment plan. It aims to see which approach helps people with Alzheimer’s who still have measurable thinking ability and specific Alzheimer’s test results.
ParisAges 50 years+ - NCT04629547RecruitingPhase 2
Sleep study to help prevent Alzheimer’s disease
This trial tests whether treating sleep issues and measuring sleep can help lower the risk of Alzheimer’s disease before it starts. It focuses on older adults with no dementia signs yet.
St Louis, MissouriAges 65 years+ - NCT04650932Recruiting
Study tests new stimulation settings for advanced Parkinson’s

Tracking outcomes during non-heart procedures in children with heart defects
This study looks at how children with congenital heart disease do during routine non-heart procedures, including medical or minor treatments that are not heart-related. It also measures how much health care they use afterward, which may help improve care planning for families.
Los Angeles, CaliforniaAges Up to 21 years - NCT04126018Recruiting
MRI scan comparison for certain leaking or narrowed heart valves
This trial studies how well different MRI images can assess heart valve problems—like leaking (regurgitation) or narrowing (stenosis). It may help doctors get clearer information, especially in people who may not respond well to cardiac resynchronization therapy (CRT).
Cleveland, OhioAges 18–90 - NCT04591587Enrolling by invitation
Corneal lenticule implant for keratoconus
This trial tests a new surgical procedure using a small piece of corneal tissue (a lenticule) from a donor to strengthen the cornea in people with progressive keratoconus. The goal is to help stop the disease from getting worse.
PristinaAges 20–40 - NCT04575883Recruiting
Bike interval training for teens with repaired heart defects
This study tests a structured “interval” bike exercise program to see if it’s safe and helpful for teens with certain repaired congenital heart conditions. It may help improve fitness while closely monitoring heart symptoms during training.
Edmonton, AlbertaAges 10–18 - NCT04576793RecruitingPhase 2
Imaging brain inflammation in Alzheimer’s and related variants over time
This Phase 2 study uses repeated brain MRI scans to track “microglial activation,” which is a marker of brain immune/inflammation activity, in different Alzheimer’s-related conditions. It may help researchers understand how brain inflammation changes over time and differs between people with these clinical variants.
New York, New YorkAges 50 years+ - NCT04580225Recruiting
Tested partial wrist fusion with or without bone removal
This study compares two surgical options for certain types of advanced wrist arthritis—one with partial wrist fusion alone, and one with partial wrist fusion plus removal of a small wrist bone. It may help find which approach works better for pain and function after surgery.
Calgary, AlbertaAges 18–75 - NCT04532346RecruitingEarly Phase 1
Hydroxychloroquine for genetic lung disease in children
This early-phase trial studies whether hydroxychloroquine can help children with certain genetic causes of interstitial lung disease (lung scarring/inflammation). It is designed for kids who are currently stable and have not recently taken hydroxychloroquine.
Shanghai, Shanghai MunicipalityAges 1 month–18 years - NCT04570085RecruitingPhase 3
Caffeine treatment to improve thinking in Alzheimer’s disease
This trial tests whether changing caffeine intake can improve thinking and brain function in people with Alzheimer’s disease. You may qualify if you can follow a low-caffeine diet and have stable Alzheimer’s treatment and sleep/heart conditions.
AmiensAges 50 years+ - NCT04397159Recruiting
Exercise program to reduce tiredness in some kidney patients
This trial studies whether doing a combination exercise program can reduce “fatigability,” meaning feeling unusually tired or weak during activity, in Veterans with moderate-to-advanced chronic kidney disease. It also compares results with people without kidney disease and checks for safety, especially for heart and joint health.
Washington D.C., District of ColumbiaAges 50–85 - NCT04440254Recruiting
Long ECG monitoring for Fabry disease heart rhythm
This study checks how your heart’s electrical rhythm looks over a longer period using an ECG (a heart rhythm recording) in people with Fabry disease. It may help doctors understand heart rhythm changes better so future care can be more tailored and safer.

- Yes. Clin2 currently lists 18,440 recruiting no disease or condition is being studied 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 no disease or condition is being studied 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 no disease or condition is being studied 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.
