Study registry for patients getting focused radiation for spread disease
This study keeps a registry (a record) of people with metastatic (spread) cancer who are receiving focused, high-dose radiation to body sites outside the brain. It aims to better understand outcomes and care patterns for these patients.
Cary, North CarolinaAges 18 years+ - NCT04086329RecruitingPhase 1
Testing an oxygen sensor during exercise in muscle disease
This early (Phase 1) study checks whether a tiny oxygen-sensing device works reliably while people with mitochondrial muscle disease (and some healthy volunteers) ride a stationary bike. The goal is to see if the sensor can measure oxygen use during exercise and help future monitoring or research.
Philadelphia, PennsylvaniaAges 18–65 - NCT04088682Recruiting
Check hospital care quality for adults with heart attacks
This trial looks at how well hospitals measure and deliver care for adults who arrive soon after a certain type of heart attack. It may help improve quality of treatment for people with acute ST-elevation myocardial infarction (a specific heart attack pattern).
Beijing, Beijing MunicipalityAges 18 years+ - NCT04094311RecruitingPhase 3
Testing a modified cell therapy when product quality is off-spec
This study looks at using tisagenlecleucel, a cell therapy, when the final product does not meet routine “commercial release” quality standards. It focuses on whether it can still be given safely and effectively to people with serious or life-threatening illness.
Hamilton, OntarioAges birth–100 years - NCT04093986Recruiting
Using past pregnancy records from women with sickle cell
This study looks back at past pregnancy and breastfeeding experiences in women with sickle cell disease who took hydroxyurea. It aims to better understand how hydroxyurea exposure may affect pregnancy and baby outcomes.
Cincinnati, OhioAges Any age - NCT04097145Recruiting
Heart valve repair for severe leaking tricuspid valve
This trial tests a catheter-based procedure (done through the blood vessels) to repair a severely leaky tricuspid valve. It may help people with symptoms or past hospitalizations from tricuspid valve leakage who are higher-risk for standard surgery.
Phoenix, ArizonaAges 18 years+ - NCT04097561RecruitingPhase 1
Belimumab safety study for low CD4 counts and autoantibodies
This Phase 1 study tests how safe belimumab is for people with idiopathic CD4 lymphopenia (low protective white blood cells) and signs of autoantibodies. It aims to learn whether the treatment is tolerable and could be a future option for people with this immune condition.
Bethesda, MarylandAges 18–70 - NCT04098744RecruitingPhase 2
Artesunate vaginal inserts for high-grade cervical changes
This Phase 2 study tests whether artesunate vaginal inserts can help treat high-grade abnormal cells on the cervix (CIN2/3). It’s meant for adults who have a confirmed high-grade precancer change and can use birth control during the study.
Fort Myers, FloridaAges 25–100 - NCT04099823Recruiting
MRI study of spinal fluid flow in memory or balance problems
This study uses MRI to look at how spinal fluid moves inside and around the brain. It aims to better understand conditions that can affect thinking, memory, balance, and coordination—such as normal pressure hydrocephalus—or compare with healthy people.
Rochester, MinnesotaAges 18 years+ - NCT04106830Recruiting
Study to follow neuroinflammation and demyelination diseases with imaging

Watching foam treatment for cysts in autosomal polycystic disease
This study follows adults with inherited kidney and/or liver cysts that are causing symptoms to see how a foam sclerotherapy procedure may help and what outcomes happen over about a year. You may be eligible if you have a few sizable, specific-type cysts and can safely attend follow-up visits.

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.
