Recruiting studies
- NCT02892877Recruiting
Study for certain pregnancy-related tumor conditions
This study is for people who have a pregnancy-related tumor called gestational trophoblastic disease. It looks at this condition in patients who were diagnosed by blood test (hCG) changes or tissue testing, to better understand and manage the disease.
Pierre-BéniteAges Any age - NCT02917460Recruiting

Proton radiation for slow-growing or benign brain tumors
This trial studies proton radiation therapy for adults with certain benign or slow-growing brain tumors. It aims to see how well tumors can be controlled, and how treatment affects quality of life and side effects.
Boston, MassachusettsAges 18 years+ - NCT02986516Recruiting
Surgery or definitive radiation for primary sacral chordoma
This trial compares two standard treatment approaches—surgery versus definitive radiation—for people with a primary sacral chordoma (a bone tumor at the lower spine/pelvis area). It aims to find which approach works best for controlling the tumor while considering treatment side effects.
GrazAges 18–80 - NCT03049462RecruitingPhase 1
Study how a beta-3 drug changes body fat in healthy adults
This Phase 1 study tests how chronic treatment with a beta-3–type medicine affects brown fat (a special kind of body fat) in the body. It mainly looks at safety and how the body responds over time, which could help future treatments for weight and metabolic health.
Bethesda, MarylandAges 18–40 - NCT03371407Recruiting
Study brain movement training in people with Parkinson’s
This study looks at how people with Parkinson’s adapt their movements and how their brain sensorimotor system works. It may help researchers improve understanding of Parkinson’s and refine movement-focused therapies.
MarseilleAges 18 years+ - NCT03358979Recruiting
3D eye-surface testing for severe dry eye
This study looks at how a specific eye-surface marker (EMMPRIN) changes on the surface cells in people with severe dry eye. It may help researchers understand disease severity and how new treatments could work for severe symptoms.
ParisAges 18 years+ - NCT03209583Recruiting
Test of fast-pacing therapy for congenital heart rhythm issues
This trial studies whether a device-based fast pacing therapy (called ATP) can better treat certain rapid heart rhythm problems in people born with a heart condition. It may help prevent or reduce episodes of atrial (upper-chamber) arrhythmias that occur despite having a pacing/defibrillator device.
Los Angeles, CaliforniaAges Any age - NCT03358693Recruiting
Study of inflammation patterns in chronic skin diseases
This study looks at molecular (body-level) signatures in people with chronic inflammatory skin conditions. You may help researchers understand what drives inflammation, while receiving standard (already approved) systemic treatment through routine care.
KielAges Any age - NCT02945345Recruiting
Test how skin scores change in cutaneous dermatomyositis
This study looks at how well skin symptoms improve in adults with cutaneous dermatomyositis by using a specific skin-scoring tool. The results may help doctors better measure treatment response and guide care.
Philadelphia, PennsylvaniaAges 18 years+ - NCT02923440Recruiting
Donate DNA and help build a congenital heart study database
This study creates a DNA bank and a French database for babies and children with certain types of congenital heart defects, to better understand genetic causes. You’ll be asked to have a blood test and share consent, even though care can continue as usual at the study hospital.
MarseilleAges Any age - NCT03035097Recruiting
Study of lung illness for people who served in Southwest Asia
This study is building a research database and stored samples from people who served in the Southwest Asia wars. It may help researchers learn what causes lung problems in veterans and how to better diagnose or treat them.
Denver, ColoradoAges 18 years+ - NCT03291392Recruiting
CUHK stroke biobank for blood, fluid, and tissue samples
This study builds a research bank using samples from people with stroke, their family members, and some people without narrowing in their blood vessels. Your samples help researchers study stroke and related brain and vessel changes.
Hong KongAges 18 years+ - NCT03260842Recruiting
Biobank study for people at high risk of pancreatic cancer
This study collects and stores samples (bio-specimens) from adults who have pancreas cysts and are at higher risk for pancreatic cancer. The goal is to help researchers improve early detection so future patients may be diagnosed sooner.
Stanford, CaliforniaAges 18 years+ - NCT03224949Recruiting
Study comparing fatty liver types and healthy livers
This study compares liver samples and blood tests from people with alcohol-related fatty liver disease, alcohol-related hepatitis, and cirrhosis (including some with liver cancer) against healthy controls. It aims to better tell these liver conditions apart and understand what is different between them.
Cleveland, OhioAges 18–75 - NCT03294954RecruitingPhase 1
GD2 CAR plus IL-15 modified cells for children with neuroblastoma
This early-phase trial tests an immune-cell treatment made from the child’s own cells, designed to attack neuroblastoma. It aims to help children whose cancer has come back or did not respond to standard treatment.
Houston, TexasAges 1–21 - NCT03204357Recruiting
Using your own blood after heart-lung machine surgery
This trial studies giving a “fresh” blood transfusion from your own blood after heart surgery that uses a heart-lung machine. It may help patients avoid needing donated blood, but it only works for people who meet specific safety and timing requirements.
Aurora, ColoradoAges 18–90 - NCT03209791Recruiting
Study alcohol-related effects on muscle recycling in the liver
This study looks at how alcoholic liver disease may change a natural body clean-up process in muscle. It compares people with alcoholic liver disease to people without it to better understand the biology and identify possible targets for treatment.
Cleveland, OhioAges 18–65 - NCT03056794Recruiting
Study of genetic and natural history of PDC deficiency
This study looks at how pyruvate dehydrogenase complex (PDC) deficiency affects people over time and what genes are involved. It mainly helps by building genetic and health data, which may improve future care and understanding of the condition.
Pittsburgh, PennsylvaniaAges Any age - NCT03240328RecruitingPhase 1
CAR-T therapy study for rebuilding HIV immune defenses
This early-stage study tests whether CAR-T cells can help rebuild the immune system’s ability to fight HIV. You may be a candidate if your HIV is well controlled on standard treatment and you don’t have certain serious infections or organ problems.
Guangzhou, GuangdongAges 18–60 - NCT02947750RecruitingPhase 2
Exercise study in people with kidney disease
This Phase 2 study tests how engaging in supervised exercise affects the body’s blood-vessel responses in people with chronic kidney disease (CKD) who don’t exercise regularly. It may help researchers understand whether exercise could be beneficial for CKD-related health changes.
Atlanta, GeorgiaAges 18–75 - NCT03109288RecruitingPhase 1/Phase 2
Biomarker-guided combination treatment for residual multiple sclerosis activity
This early-phase study tests combination treatments for multiple sclerosis (MS) based on lab “biomarkers” found in the spinal fluid. It aims to reduce ongoing MS activity and help determine which treatment combinations may work best for different people.
Bethesda, MarylandAges 18–120 - NCT02936791Recruiting
Study of early inherited kidney cysts and healthy volunteers
This observational study follows people early in autosomal dominant polycystic kidney disease (ADPKD) and also some healthy volunteers to learn how the kidneys work over time. It may help researchers understand early changes, which could guide future treatments.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,813 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.
