Shanghai, Shanghai MunicipalityAges 18–75 - NCT04049539RecruitingPhase 1/Phase 2
Vyxeos for AML that stays after initial chemotherapy
This trial tests whether Vyxeos (a type of chemotherapy) can treat acute myeloid leukemia (AML) that did not fully go away after standard induction (“7+3”) chemotherapy. It targets people whose leukemia is still present in the bone marrow and need a stronger “re-induction” treatment.
Sacramento, CaliforniaAges 18–75 - 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+ - NCT04055818RecruitingPhase 1
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+ - NCT04068480Recruiting
Robotic magnetic capsule to check the small bowel
This trial tests a capsule camera that doctors can steer using magnets to look at the small intestine. It may help patients who need small-bowel endoscopy when a standard approach isn’t enough, but several safety checks are required.

Quality of life study for heart disease patients
This study asks people with certain heart conditions to complete follow-up questionnaires to better understand how their quality of life changes over time. It may help improve how care plans are made and supported for patients and their families.
Cleveland, OhioAges 18–70 - NCT04087031Recruiting
Tech-based rehab for early Parkinson’s symptoms in older adults
This trial tests an innovative, technology-supported rehabilitation program to help older adults with early-stage Parkinson’s disease improve daily function. It may be helpful if your symptoms are mild and your treatments have been stable for at least a month.
AnconaAges 65 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+ - NCT04099992Recruiting
Mindfulness program for people with chronic kidney disease
This trial tests whether a mindfulness-based program can help people living with moderate-to-advanced kidney disease. It may improve how you feel day-to-day and how you manage symptoms, while researchers track kidney-related health and safety.
Atlanta, GeorgiaAges 40–80 - NCT04099966RecruitingPhase 2
Stem cell transplant to treat high-risk blood cancers
This trial tests a specialized donor stem cell transplant to treat high-risk problems in the blood and bone marrow, including some cancers and non-cancers. It may help by using donor immune cells designed to better control the disease after transplant.
Valhalla, New YorkAges 1 day–30 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+ - NCT04114994Recruiting
Memory testing study for adults 50 and older
This study checks how people’s thinking and memory change over time using a specific cognitive test. It may help researchers understand patterns of memory change and supports future research on brain health.
Miami, FloridaAges 50 years+ - NCT04126018Recruiting
MRI scan comparison for certain leaking or narrowed heart valves
This trial studies how well different MRI images can assess heart valve problems—like leaking (regurgitation) or narrowing (stenosis). It may help doctors get clearer information, especially in people who may not respond well to cardiac resynchronization therapy (CRT).
Cleveland, OhioAges 18–90 - NCT04119908Recruiting
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+ - 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 - 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.

KRAS-mutant pancreatic cancer T-cell therapy for some people
This Phase 1/2 study tests a lab-made immune cell (T-cell) treatment that targets a specific KRAS mutation (G12V) found in some pancreatic cancers. It may help shrink tumors or control cancer growth after standard treatment, and it mainly focuses on safety and early effectiveness.
ShanghaiAges 18–75 - NCT04160429Recruiting
Biospecimen testing to measure chemicals during treatment

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.
