Recruiting studies
- NCT03633708RecruitingPhase 3
Etelcalcetide for children with dialysis-related overactive parathyroid hormone
This trial studies etelcalcetide in children who have chronic kidney disease and too much parathyroid hormone while on hemodialysis. It aims to safely lower the hormone levels and help manage related bone/mineral problems.
Los Angeles, CaliforniaAges birth–18 years - NCT03653156Recruiting
Aging and brain study for mild memory loss and dementia
This study checks how age affects memory and thinking, and compares people with mild memory problems, Alzheimer’s disease types, vascular dementia, and healthy controls. You may help researchers understand brain changes using thinking tests, MRI scans, and blood or spinal fluid tests.
Hefei, AnhuiAges 18 years+ - NCT03657732Recruiting
Study of inherited Alzheimer’s genes in families
This study looks at people from families with inherited Alzheimer’s disease, including those who may be cognitively normal. It uses medical checkups and brain/nerve tests to better understand Alzheimer’s risk and symptoms in families with specific gene changes.
Hefei, AnhuiAges 18 years+ - NCT03657745Recruiting
40 Hz light and brain training for Alzheimer’s
This trial tests whether a combination of 40 Hz light stimulation and cognitive (thinking) therapy can improve symptoms in people with Alzheimer’s disease. It may help by stimulating the brain and training thinking skills, while carefully checking eye and seizure history.
Miami, FloridaAges 50 years+ - NCT03663777Recruiting
Hand strength training for women with poor leg blood flow
This trial tests whether guided handgrip (hand strength) exercises can improve health in post-menopausal women who have reduced blood flow to the legs. It may help your circulation and overall function, as long as you can safely do the training and keep your current medications during the study.
São Paulo, São PauloAges 45 years+ - NCT03671889Recruiting
Ultrasound treatment to open the brain barrier for Alzheimer’s
This trial tests a non-surgical ultrasound procedure (called MR-guided focused ultrasound) meant to temporarily “open” the brain’s protective barrier so treatments may work better for Alzheimer’s disease. It also looks at safety and how well people tolerate the procedure and related tests.
Delray Beach, FloridaAges 50–85 - NCT03681652Recruiting
Study of recovery outcomes after Crohn’s surgery in children
This study looks at outcomes after children with Crohn’s disease have part of the bowel removed (ileo-cecal resection). It may help doctors improve post-surgery care, especially for preventing flare-ups in the months after surgery.
Petah Tikva, IsraelAges 6–18 - NCT03711539Recruiting
Exercise program study to help prevent clogged heart arteries
This trial studies whether lifetime endurance exercise is linked to a lower risk of coronary artery disease (clogged heart arteries). It may help explain which people benefit most from regular endurance activity and who may need different prevention steps.
EdegemAges 45–70 - NCT03711617Recruiting
Study of waste products and outcomes in chronic kidney disease
This study looks at “uremic toxins,” which are waste products that build up when kidney function is reduced, and how they relate to health outcomes in people with chronic kidney disease. The results may help doctors better understand what to monitor and target to improve care.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT03716401Recruiting
Imaging tests to predict kidney disease in type 2 diabetes
This study uses special kidney imaging to look for patterns that can predict how diabetic kidney disease may progress. It may help researchers find better ways to identify people at higher risk using noninvasive (and possibly biopsy-related) tests.
TurkuAges 18–80 - NCT03732612Recruiting
Studies inflammation markers around upcoming vascular surgery
This study looks at signs of “inflammation” (your body’s immune response) in people who are scheduled for vascular surgery. It may help researchers understand what’s happening in blood vessel disease and improve future care.
Gothenburg, VastragotalandAges 18 years+ - NCT03773887Recruiting
Study of liver inflammation and healing in alcohol-related liver disease
This study compares patterns of liver inflammation and the liver’s healing ability in people with alcohol-related liver disease, using blood tests and (in most cases) a liver tissue sample. It may help doctors better understand what is happening in the liver and how it may recover.
LilleAges 18–70 - NCT03774446RecruitingPhase 2
Seliciclib trial for Cushing disease from a pituitary tumor
This Phase 2 study tests seliciclib (also called R-roscovitine) in people with Cushing disease caused by a pituitary tumor and ongoing high cortisol levels. It may help reduce excess cortisol production in those whose Cushing disease has not fully gone away or has come back after standard treatment.
Los Angeles, CaliforniaAges 18 years+ - NCT03781492Recruiting
Treatment study for stable angina symptoms
This study looks at managing and treating stable angina, a type of chest discomfort that happens predictably with activity or stress. It may help find better ways to control symptoms and improve daily life, but you must not have certain recent heart events to join.
Zabrze, Silesian VoivodeshipAges 18 years+ - NCT03786549Recruiting
Sickle cell care transition program for teens and families
This study tests a structured program to help teens with sickle cell disease smoothly transition from pediatric care to adult care, with support for parents or legal guardians. It may help families coordinate care sooner and more confidently during this change.
Fort-de-France-La Martinique, La MartiniqueAges 16–17 - NCT03788512Recruiting
Registry study for recent stroke/TIA with heart artery disease
This study enrolls people who recently had an ischemic stroke or a TIA (a “mini-stroke”) and also have evidence of narrowed heart arteries. It collects information to better understand how brain and heart artery disease occur together and may guide future care.
Beijing, BJAges 18–85 - NCT03797183Recruiting
Check heart and lung function using a painless chest scan
This study uses a noninvasive scan that measures electrical signals across the chest to better understand breathing and heart-related circulation problems. It may help doctors learn what to monitor and how conditions like lung/airway pressure and vessel narrowing progress.
Aurora, ColoradoAges 2 weeks–40 years - NCT03800017Recruiting
Muscle strength and exercise function in lung scarring
This study looks at how well skeletal (muscle) function supports exercise in people with interstitial lung diseases (including idiopathic pulmonary fibrosis). It may help better understand fitness and breathing limits, which can guide rehabilitation choices and future care.
Vancouver, British ColumbiaAges 40–80 - NCT03803423Recruiting
Using social media to find kidney or liver donors
This study tests a way to spread information on how to register as a live organ donor using social media. You may be contacted to help identify potential live kidney or liver donors, if you fit the study’s basic requirements.
San Diego, CaliforniaAges 18 years+ - NCT03807687Recruiting

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,802 recruiting general population (no specific condition or disease) 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 general population (no specific condition or disease) 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 general population (no specific condition or disease) 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.
