Testing three medicines for high-risk sickle cell disease
This Phase 1 study tests whether nicotinamide, oral tetrahydrouridine, and decitabine can help people with high-risk sickle cell disease. It is mainly a safety-and-dosing study, but it also looks for signs the medicines may improve disease-related problems.
Chicago, IllinoisAges 18 years+ - NCT04055571Recruiting
Review of pancreatic disease treatments since 2005

Test video microscopy to predict bleeding risk
This study uses special video imaging to try to predict when bleeding may happen in certain inherited bleeding disorders. It may help doctors better anticipate bleeding and guide safer care.
Lille, NordAges 18 years+ - NCT04078412Enrolling by invitation
Registry for adults with nontuberculous lung infection
This is a research registry that collects information from adults diagnosed with nontuberculous mycobacterial (NTM) lung disease. It may help doctors better understand the disease and improve care over time.
SeoulAges 20 years+ - NCT04106518Recruiting
Genetics study of alcohol-related liver disease and cirrhosis
This study looks at genetic differences in people with alcohol-related liver illness, including a recent jaundice episode (alcoholic hepatitis). By following people over time, it may help doctors better predict illness and understand why some people develop worse liver problems.
AngersAges 18 years+ - NCT04098354Recruiting
Phone monitoring for high blood pressure in kidney disease
This study tests whether using a home blood pressure monitoring device and phone-based check-ins can help people with high blood pressure and chronic kidney disease manage their health better. You may be asked to record readings and send them regularly during the study.
Edmonton, AlbertAges 18 years+ - NCT04124120Recruiting
Single vs multiple bypass grafts for women heart surgery
This study compares outcomes of using one bypass graft versus multiple bypass grafts during coronary artery bypass surgery in women. It aims to see which approach leads to better recovery and heart outcomes for eligible patients.
Los Angeles, CaliforniaAges 18 years+ - NCT04055428RecruitingPhase 2
Testing a hormone supplement to improve heart and metabolic health
This study tests whether adding a natriuretic peptide medicine improves heart health and metabolism in Black adults. It may help with blood pressure and related health markers, but you must meet specific health and safety criteria.
Birmingham, AlabamaAges 18 years+ - NCT04123314RecruitingEarly Phase 1
Psilocybin study for depression in mild memory or early Alzheimer’s
This early-phase study tests whether psilocybin (a psychedelic substance) can help with depression in people who have mild memory problems or early Alzheimer’s. The trial also closely monitors safety, thinking changes, mood, and blood pressure before and after dosing.
Baltimore, MarylandAges 18–85 - NCT04141592Recruiting

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.
