Recruiting studies
- NCT04815928Recruiting

Vancomycin powder during spine surgery to prevent infection
This trial studies whether placing antibiotic powder (vancomycin) directly in the surgical wound during spine surgery can lower the chance of infection. It may help patients by reducing wound infections after surgery, but it also depends on your surgery details and follow-up timeline.
Windsor, OntarioAges 18 years+ - NCT04827498Recruiting
Testing heart blood-flow problems without clogged arteries
This study looks at how well the heart’s blood vessels work in people who have symptoms of reduced blood flow but no major artery blockage. It uses special heart tests with medicines to check how the vessels respond and may help guide better diagnosis and treatment.
MadridAges 18 years+ - NCT04827316Recruiting
Use CT heart scans to predict outcomes and guide care
This study looks at people who are having a CT scan of their heart because it’s medically needed. Researchers will use the scan results to better predict future cardiovascular outcomes and improve how care decisions are made.
BernAges 18 years+ - NCT04838171Recruiting
Study of White Blood Cells in Donors and Patients
This study looks at white blood cells (the body’s immune cells) to learn more about how they behave in health and/or illness. Participation may help researchers understand immune-related changes and support future treatments.
LondonAges Any age - NCT04839757Recruiting
Testing a dengue vaccine plan for kids in the Caribbean
This trial looks at a dengue vaccine strategy in children ages 9 to 17 in Martinique and Guadeloupe. It may help protect kids from dengue, based on how the vaccine is accepted and how the study is carried out.
Fort-de-FranceAges 9–17 - NCT04842006Recruiting
Personalized treatment plan for rectal cancer before and after surgery

Helsinki, UusimaaAges 18–100 - NCT04846959Recruiting
Pregnancy outcomes study for people exposed to risankizumab
This study looks at pregnancy outcomes in people who took risankizumab during pregnancy (or shortly before getting pregnant). It compares them with pregnancies exposed to similar biologic medicines, to better understand risks and what to expect.
Morrisville, North CarolinaAges Any age - NCT04848636Recruiting
Sodium MRI scan to study heart salt changes in kidney disease
This trial uses a special MRI scan (called sodium MRI) to measure salt (sodium) in the heart. It compares people with chronic kidney disease (including those on hemodialysis) to healthy volunteers to understand how kidney disease may affect the heart.
London, OntarioAges 18 years+ - NCT04851015RecruitingPhase 3
Low-dose TMP-SMX for Pneumocystis pneumonia (PCP)
This Phase 3 study tests whether low-dose trimethoprim-sulfamethoxazole (also called TMP-SMX) can treat Pneumocystis pneumonia (PCP) in people with weakened immune systems. It may help improve treatment while reducing side effects compared with standard dosing.
Montreal, QuebecAges 18–100 - NCT04854213Recruiting
Study checks radiation effects in colon cancer lung-limited spread
This trial studies how targeted radiation (SBRT) affects cancer biology and immune cells in people with colon cancer that has spread only to a small number of lung nodules. Your tumor tissue will be analyzed to see what changes after treatment.
Naples, NAPOLIAges 18–80 - NCT04855630Recruiting
Sleep and mild exercise program for thinking and memory support
This study tests whether combining better sleep routines with mild exercise can help with memory, concentration, and thinking speed. To do that, you would wear special devices and complete quick at-home and in-person assessments and a small finger-prick blood test.
Miami, FloridaAges 45–80 - NCT04855773Recruiting
Mobile text-message support to help people stay on PrEP
This trial tests whether phone-based (iPhone/Android) text-message support can improve how consistently people use PrEP, an HIV prevention medicine. It may help you stay on track with refills and clinic visits, especially if you’re at higher risk of stopping PrEP.
San Francisco, CaliforniaAges 15 years+ - NCT04856059Recruiting
MRI study for early heart changes in Fabry disease
This study looks at early structural and tissue changes in the heart using a special type of MRI scan in adults with Fabry disease. It may help doctors understand changes earlier and better track heart involvement over time.
Toronto, OntarioAges 18 years+ - NCT04856488RecruitingPhase 3
Lugol’s iodine solution before thyroid surgery for overactive thyroid
This trial tests whether taking Lugol’s iodine solution before thyroid surgery is safe and helpful for people with Graves’ disease or toxic nodular goiter (overactive thyroid). It may be aimed at improving surgical readiness and outcomes by reducing thyroid activity before the operation.
Solna, Stockholm CountyAges 18–75 - NCT04859088Recruiting
Biologics plus partial tube-feeding for Crohn’s disease
This study tests whether starting adalimumab along with partial enteral (tube or drink) nutrition helps control active Crohn’s disease. It may help reduce symptoms and inflammation compared with standard care alone.
Glasgow, ScotlandAges 16 years+ - NCT04861506Recruiting
Clot-removal treatment for blocked blood flow in the leg
This trial tests how safe and effective a clot-removal procedure done through the blood vessels is for people with acute or subacute blocked blood flow in the lower leg. It may help by improving circulation while carefully tracking risks and results.
Hangzhou, ZhejiangAges 18 years+ - NCT04864145Recruiting
Valve procedure trial for severe leaking aortic valve
This trial studies a less invasive heart valve procedure that places a new valve through a catheter, to treat severe leakage of the aortic valve. It may help people who have symptoms or heart enlargement and who are at higher risk for open-heart surgery.
Nanjing, JiangsuAges 60–90 - NCT04876339Recruiting
Sound-based training to improve walking after brain illness
This study tests whether using special sounds (sonification) during gait training can improve walking for people with stroke, Parkinson’s disease, or multiple sclerosis. It may help your walking speed, stamina (fatigue), and overall walking pattern.
PaviaAges Up to 80 years - NCT04882488Recruiting
Testing heart scan measurements in severe aortic valve narrowing
This trial compares two pressure-based measurements of blood flow in the coronary arteries with a PET heart scan in people with severe aortic valve stenosis. It may help doctors choose the most accurate way to assess blood flow and guide care during valve treatment.
Bad Oeynhausen, North Rhine-WestphaliaAges 65 years+ - NCT04885985Recruiting
Check a new treatment for blocked leg arteries after procedures
This post-market study follows people with significant below-the-knee artery blockages to see how a treatment performs over time. It may help patients by confirming the safety and ongoing effectiveness of the device used for these leg artery problems.

Common questions
- Are there clinical trials for disease?
- Yes. Clin2 currently lists 9,583 recruiting 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 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 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.
