Recruiting studies
- NCT03737955RecruitingPhase 2
Gemtuzumab for measurable residual leukemia after initial treatment

This study checks unborn babies’ heart signals using special scans during pregnancy and then checks the baby’s heart shortly after birth. It may help researchers understand why certain high-risk pregnancies can lead to fetal demise and improve care.
Madison, WisconsinAges 18 years+ - NCT03791970Recruiting
Compare stent post-dilation using drug balloon or regular balloon
This study looks at whether using a drug-coated balloon (DCB) versus a regular balloon (POBA) right after placing a stent works better in artery blockages in the thigh/knee area. It may help improve blood flow and reduce the chance the artery narrows again.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT03799354Recruiting
Strength training study for people with COPD
This trial tests whether a maximal strength training program can help people with COPD who are stable. It is looking at people with moderate-to-severe airflow limitation and excludes several other lung and health problems.

This study collects blood (and sometimes tissue samples) from people who may have vascular (blood vessel) problems and from certain pregnant participants. Researchers use the samples to better understand vascular disease and to help guide future research.
Bethesda, MarylandAges 2–100 - NCT03685721Recruiting
Study genes in sickle cell disease to compare blood test activity
This study looks at how a person’s genes relate to certain measurements in red blood cells in people with sickle cell disease. The goal is to understand why blood cell function varies and how that might guide future care.
Bethesda, MarylandAges 18–80 - NCT03604835Recruiting
MPS VII monitoring program for patients and caregivers
This trial enrolls people with mucopolysaccharidosis type VII (MPS VII) to track their health over time. It may help your care team better understand how the condition behaves and how monitoring should be done.
Orange, CaliforniaAges Any age - NCT03664609Recruiting
Study of outcomes for people with deep brain stimulation
This study looks back at results for people who have already had deep brain stimulation (DBS) or could get it. It aims to understand how DBS is used and what outcomes people experience.
Phoenix, ArizonaAges Any age - NCT03649490Enrolling by invitation
Testing new spinal implant materials for XLIF fusion
This study compares different advanced materials used in a specific spinal fusion surgery (XLIF). It aims to see which implant material helps the bone fuse well and safely over time.
Hartford, ConnecticutAges 18–80 - NCT03576573Enrolling by invitation
Follow-up study for specific hip replacement components
This study checks outcomes after a specific type of hip surgery using specific brand parts. You may help by sharing follow-up visit information so the sponsor can confirm the components work as expected in everyday patients.
BuxtehudeAges 21 years+ - NCT03586258Recruiting
Brain scan and memory testing for people with brain injury
This study uses memory and thinking tests along with brain scans (likely MRI) to understand how different types of brain damage affect thinking. It may help doctors learn more about brain-related cognitive problems.
CaenAges 18 years+ - NCT03630211RecruitingPhase 2
Study of stem cell transplant for systemic sclerosis in youth
This Phase 2 study tests whether an “autologous” stem cell transplant—using your own stem cells—can reduce systemic sclerosis disease activity. It is mainly for children, teens, and young adults whose disease did not improve despite standard medicines.
Pittsburgh, PennsylvaniaAges 8–60 - NCT03573089Recruiting
Testing higher vs standard phosphate targets in dialysis patients
This trial compares two treatment goals for blood phosphate levels in people with end-stage kidney disease who are on dialysis. It may help determine which target is safer and works better in real-world care.
Camperdown, New South WalesAges 18 years+ - NCT03524222Recruiting
Home hospital care for adults after sudden illness
This trial tests whether certain adults can safely receive hospital-level care at home instead of staying in the hospital, using a home care team. It may help you recover in your own home if your condition fits their plan and you have support at home.
Boston, MassachusettsAges 18 years+ - NCT03572465Recruiting
Ultrasound tests to diagnose fatty liver inflammation
This study checks whether special ultrasound measurements can help diagnose nonalcoholic steatohepatitis (NASH), a type of fatty liver disease. You may need a liver biopsy as part of routine care, and you may also be scanned with MRI to support the study tests.
Montreal, QuebecAges 18 years+ - NCT03577327Recruiting
Study gut and skin germs in vitiligo progression
This study looks at differences in the gut and skin microbiome (the germs living in and on the body) in people with vitiligo and in people without vitiligo. It aims to understand what might be linked to how vitiligo spreads over time.
Chicago, IllinoisAges 18–89 - NCT03666052Enrolling by invitation
Study for kids with severe nearsightedness in Shanghai
This study registers children and teens in Shanghai who have significant nearsightedness, to better track eye health over time. It may help researchers understand why high myopia develops and how to prevent or monitor complications.

Bone marrow transplant using donor blood to treat sickle cell
This trial tests a specific type of bone marrow transplant for people with sickle cell disease (or certain other blood disorders) who have had serious complications despite standard care. It aims to see if removing the patient’s immune cells and using a matched donor’s cells can improve outcomes and reduce complications.
Pittsburgh, PennsylvaniaAges 5–40 - 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.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,548 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.
