Brain monitoring in unconscious ICU patients after cardiac arrest
This trial tests a bedside brain-monitoring method (near-infrared light and EEG) in people who are unconscious after severe brain injury from cardiac arrest. The goal is to see whether it can help measure brain function during the first week after admission.
Zurich, Canton of ZurichAges 18 years+ - NCT04743362Recruiting
Noninvasive scans for skin and mouth lesions
This trial tests noninvasive imaging methods to look at skin and mouth (mucosal) conditions. It may help doctors better see changes in these areas without taking tissue samples.
New York, New YorkAges Any age - NCT04754217Recruiting
Follow-up study after valve graft replacement
This study looks at outcomes after certain heart valve surgeries using a valved graft. It may help doctors understand how well these grafts work over time in people who have had valve replacement surgery.
Birmingham, AlabamaAges 18 years+ - NCT04689854Enrolling by invitation
Cervical spine surgery implant study for neck disc problems
This trial studies specific neck (cervical) spine implants used during surgery for degenerative disc disease or neck instability, along with a particular kind of bone grafting and supporting hardware. It may help patients by testing whether these devices and the planned fusion approach work safely and effectively in real-world surgery.
Orange, CaliforniaAges 18 years+ - NCT04734756Enrolling by invitation
Dragonfly device study for leaking mitral valve in high-risk patients
This trial tests the safety and effectiveness of a heart procedure that repairs a leaking mitral valve through thin tubes, using the Dragonfly system. It’s for people who have significant mitral valve leak symptoms but are considered high risk for open-heart surgery.
Hangzhou, ZhejiangAges 18 years+ - NCT04761120Recruiting
Follow-up study for specific heart valve repair ring implants
This study follows people who are going to get certain types of heart valve repair rings or bands. It aims to track safety and outcomes after the Abbott device is implanted in routine care over follow-up visits.
Durham, North CarolinaAges 18 years+ - NCT04604782RecruitingPhase 1/Phase 2
Regadenoson study in children to test safety and dosing
This trial tests how safe regadenoson is in children and how the body handles it after dosing. It also uses a heart “stress test” with MRI (CMR) when doctors feel it’s needed.
ParisAges 4 weeks–18 years - NCT04679844Recruiting
Test bone putty for back fusion versus bone graft alternatives
This study compares a ready-to-use bone putty to standard bone graft materials (with or without your own bone) during back fusion surgery for unstable lower back problems. It looks at whether the putty works as well or better to help the bones fuse and heal.
Irvine, CaliforniaAges 18 years+ - NCT04681781Enrolling by invitation
Remote study of SLC13A5 deficiency history
This study follows people with SLC13A5 deficiency to better understand how the condition changes over time, using surveys and clinical check-ins done remotely. If you (or your child) have this genetic condition, it may help researchers learn what symptoms to expect and how to track them.
Palo Alto, CaliforniaAges Any age - NCT04680130Enrolling by invitation
Study of brain, genetics, and clinical symptoms in neurodegenerative illness
This study looks at how your symptoms, brain imaging (MRI), and genetic factors relate to neurodegenerative conditions. It may help researchers better understand what causes these illnesses and how to classify them.
Rochester, MinnesotaAges 21 years+ - NCT04664556Recruiting
Study of severe pneumococcal infections in children
This study tracks cases of invasive pneumococcal disease (a serious infection) in children and newborns. It may help clinicians better understand how these infections happen and guide future prevention and treatment.
CréteilAges 1 day–18 years - NCT04634383Recruiting
Testing a brain-connected implant to help some blind people see
This early safety study tests an implanted device placed in the brain to help people with very limited sight (no or minimal light). It focuses on whether the implant can be safely used and whether it may support vision-related signals over time.
Chicago, IllinoisAges 19–70 - NCT04528355Recruiting
Study of hospital data after stem cell transplant for non-cancer illness
This study collects medical information from people with certain non-cancer conditions who receive a stem cell transplant. It may help doctors better understand transplant outcomes and care, since the study focuses on data collection rather than adding new treatment.
Pittsburgh, PennsylvaniaAges 2 months–60 years - NCT04514445Recruiting
Study of genes in people with bicuspid aortic valve
This study looks for genetic (inherited) differences that may be linked to bicuspid aortic valve (BAV). It includes people with BAV and close family members to help understand why BAV happens and whether genes play a role.
KetteringAges 10–99 - NCT04472338Recruiting
Prostate cancer screening for people with higher genetic risk
This study looks at prostate cancer screening for people who may be at higher risk because of a specific inherited (genetic) change. It may help your care team find the best screening approach to catch aggressive prostate cancer earlier.
Duarte, CaliforniaAges 40 years+ - NCT04388943Recruiting
BRICCS study: health data for cardiovascular research
This trial helps researchers study heart (cardiovascular) conditions using information collected about your care. It may help improve how doctors understand and treat cardiovascular diseases over time.
LeicesterAges 18–90 - NCT04442100Recruiting
Testing a new easy-change heart valve replacement system
This study tests a biological (tissue) heart valve replacement system designed to be easier to change later. It may help people who need valve surgery because their valve is narrowed or damaged.
Tomsk, Tomsk OblastAges 60 years+ - NCT04418830Enrolling by invitation
Study of a spine cage implant for degenerative back problems
This trial studies how well specific lumbar (lower back) implant “cages” help fuse vertebrae in people with degenerative disc disease, spinal slippage, narrowing, curvature, or forward-bending deformity. It may help by testing an approach to improve stability and reduce symptoms after surgery.
La Jolla, CaliforniaAges 18 years+ - NCT04312633Recruiting
Testing a new throat biopsy mapping method for Barrett’s disease
This study follows people for 5 years to see how well a new biopsy-mapping test (WATS3D) works during routine upper endoscopy. It may help doctors find Barrett’s esophagus changes earlier and better guide follow-up after treatment.
Bethpage, New YorkAges 18 years+ - NCT04321512Recruiting
Blood test study for people with heart or stroke problems
This study looks at a type of white blood cell (monocytes) in blood to understand differences in people with certain heart attacks, stable heart disease, or ischemic stroke. It may help researchers learn why these conditions happen and how the immune system may be involved.
Farmington, ConnecticutAges 18 years+ - NCT04365855Recruiting

- Yes. Clin2 currently lists 18,394 recruiting no disease or condition is being studied 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 no disease or condition is being studied 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 no disease or condition is being studied 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.
