Surgery changes for preventing irregular heart rhythms during bypass
This trial studies whether removing a small heart pouch area and a specific ligament during off-pump heart bypass surgery improves outcomes. It is meant for people having their first off-pump coronary bypass, without a history of atrial fibrillation.
BeijingAges 18–80 - NCT04224558RecruitingPhase 1/Phase 2
Stem cell transplant for hard-to-control Crohn’s disease
This early-phase study tests whether a stem cell transplant can improve Crohn’s disease in teens and young adults whose disease is active and not responding to standard medicines. It may help some people who are not doing well despite several prior treatments, but it also involves intensive study procedures and safety checks.
Los Angeles, CaliforniaAges 13–28 - NCT04228978Recruiting
Lifestyle weight-loss program for people with PAD to stay mobile
This trial tests whether a healthy-lifestyle weight-loss program can help people with peripheral artery disease (PAD) lose weight and prevent worsening mobility. You may be eligible if you have PAD based on specific leg blood-flow test results and a higher body weight.
Chicago, IllinoisAges 18 years+ - NCT04232982Recruiting
Cyclophotocoagulation during Boston keratoprosthesis eye surgery
This trial looks at whether a specific eye laser treatment done through the white of the eye (called transscleral cyclophotocoagulation) works well and is safe for people getting a Boston keratoprosthesis. It may help improve comfort and vision outcomes for selected patients needing this type of cornea/eye replacement surgery.
Montreal, QuebecAges 18–80 - NCT04236726Recruiting
Quality of life study for people with chronic breathing failure
This study looks at how chronic respiratory failure affects day-to-day quality of life. It enrolls people who use breathing support at home or in care, and may help clinicians understand what support works best for patients’ daily living.
LondonAges 18 years+ - NCT04243525Recruiting
Inflammatory bowel disease patient research registry
This study is a research registry that collects information from adults receiving care for inflammatory bowel disease at UPMC. It may help researchers better understand bowel disease and improve future treatments.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT04252781Recruiting
Study for people with new or suspected COPD risk
This study follows people who currently smoke and people who may have newly found COPD (chronic obstructive lung disease) based on breathing test results. It aims to better understand lung disease in real life and what it means for health over time.
Créteil, Île-de-France RegionAges 35 years+ - NCT04252066Recruiting
Pregnancy and breastfeeding study for women with Fabry disease

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.
