New surgical method to reduce acid reflux after weight loss surgery
This trial tests a modified version of sleeve gastrectomy that aims to reduce the risk of acid reflux (GERD) after surgery. It is for people aged 18–65 with a BMI between 35 and 55 who already have some degree of GERD and are planning to have weight loss surgery.
Orange, CaliforniaAges 18–65 - NCT06954740RecruitingPhase 2

Local treatment for Crohn’s fistulas using your own fat cells
This Phase 2 trial studies whether a local injection of fat-derived cells (made from your own tissue) can improve difficult Crohn’s disease fistulas around the anus. It’s designed for people whose Crohn’s fistulas have not responded to usual treatments.
Marseille, PACAAges 18 years+ - NCT04011527Recruiting
Registry for heart stent procedure using rotational atherectomy
This study collects information from people who are having a heart procedure called rotational atherectomy to open blocked heart arteries. It helps doctors better understand how the procedure is used and its outcomes.
Bad SegebergAges 18–100 - NCT04014803RecruitingPhase 4
Aspirin plus one blood thinner versus aspirin plus clopidogrel
This trial compares two common “blood thinner” combinations to prevent problems after a PCI procedure for complex blocked heart arteries. It may help your care team find which combination works better for people with higher-risk artery patterns.
SeoulAges 19–75 - NCT04016649Recruiting
Study measures how leg veins move and respond
This study measures the properties of human saphenous and popliteal veins. If you’re having certain lower-leg procedures, your care team may collect information to better understand vein function and support future treatment.
Limerick, LimerickAges 18 years+ - NCT04020536Recruiting
Real-world study for several infectious diseases
This study follows people with confirmed brucellosis, epidemic hemorrhagic fever, or kala-azar (visceral leishmaniasis) to understand how these infections behave in real life. It may help improve care by collecting evidence on diagnosis and treatment outcomes.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT04024761RecruitingPhase 1
NK cell therapy for leukemia relapse after transplant
This Phase 1 study tests whether an infusion of special immune cells (NK cells) from a donor can help control leukemia or related blood cancers that come back or do not fully go away after a stem cell transplant. It also uses short chemotherapy to “make space” for the NK cells to work, and IL-2 to help them function.
Boston, MassachusettsAges 12 years+ - NCT04026360Recruiting
Study early lung, virus, and gut changes in children with cystic fibrosis
This study looks at how a child’s early lung function, viral infections, and gut (microbiome) changes affect cystic fibrosis over time. It may help doctors understand what predicts how lung disease develops, which could improve future care.
BernAges birth–18 years - NCT04028687Recruiting
Study of a hip stem used in select adult hip replacements
This trial follows people who have had a hip replacement using a specific “Taperloc Complete” stem. It is meant to monitor outcomes after surgery and see how well the stem performs over time for certain non-infectious hip problems.
Henderson, NevadaAges 18 years+ - NCT04036357Recruiting
Study of liver fat disease with heart and metabolism problems
This study looks at people with fatty liver disease and common health issues like obesity, diabetes, high blood pressure, or abnormal cholesterol. It may help researchers understand how liver fat and heart/metabolism problems relate and how they affect health over time.
RomeAges 18–80 - NCT04039061Recruiting
Study registry for people with ADPKD
This trial is a patient registry that collects information from people who have—or might have—autosomal dominant polycystic kidney disease (ADPKD). It may help researchers better understand the condition and improve future studies.
Kansas City, MissouriAges Any age - NCT04040777Recruiting
Cardiometabolic risk registry for adults
This study is a health registry that collects information about risk factors for heart and metabolic problems in adults. It may help doctors better understand who is at higher risk and guide future prevention strategies.
Pilar, Buenos AiresAges 18 years+ - NCT04044963Recruiting
Exercise program before kidney transplant to improve physical strength
This trial tests whether a home exercise program before kidney transplant can improve physical function and strength. If you’re getting a transplant and can safely exercise, you may be able to join the study and help compare outcomes.
Vancouver, British ColumbiaAges 19 years+ - NCT04052022Recruiting
Study of TB flare-ups in people without HIV
This study looks at why some people with tuberculosis (TB) get worse or develop new inflammation after they initially start improving on treatment—called a “paradoxical reaction.” It collects blood and tissue samples to better understand these flare-ups and guide future care.
Bethesda, MarylandAges 18–99 - NCT04058457Recruiting
Deep brain stimulation for people with Parkinson’s
This study looks at how deep brain stimulation (DBS) affects breathing in people who have Parkinson’s disease and are planning DBS surgery. You may be able to help researchers learn whether DBS changes breathing and how to manage it safely.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,808 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.
