Stent repair versus best medical care for type B dissection
This trial compares an endovascular stent (placed through blood vessels) to best medical therapy (blood pressure and pain control) for certain “uncomplicated” type B aortic dissections. It aims to see which approach works better in the early period after symptoms start.
Houston, TexasAges 18 years+ - NCT04869436RecruitingPhase 4

Toronto, OntarioAges 18–65 - NCT05483465RecruitingPhase 4
NAD supplement trial for brain blood vessel health in aging
This trial studies whether taking an NAD supplement can support brain blood vessel health as people age. Participants will be tested for brain and health changes and may help researchers understand how to keep the brain’s blood vessels healthier over time.
Oklahoma City, OklahomaAges 60–85 - NCT03906617RecruitingPhase 4
Pain-relief shots for lung surgery: three drug options compared
This study compares different pain-relief medications given during lung surgery to see which one controls pain better. It may help people have less post-surgery pain after robotic wedge resection or lobectomy.
Camden, New JerseyAges 18–90 - NCT01130545Recruiting
MRI testing of different scan methods in older adults
This study tests different MRI imaging techniques to improve how scans look and measure targets. You may be able to join with or without a contrast dye, and you’ll need to travel to the NIH for follow-up visits.
Bethesda, MarylandAges 18–100 - NCT05174351Recruiting
Stopping beta-blockers in heart failure with preserved pumping
This study checks whether safely stopping beta-blocker medicine is possible in some people with heart failure with preserved pumping (EF ≥50%). It may help by testing whether reducing the medication is safe and workable for certain patients.
Farmington, ConnecticutAges 50–80 - NCT04980794Recruiting
Family conflict resolution program for two-caregiver families
This study tests a family conflict-resolution program to help reduce conflict and improve how families handle disagreements over time. It’s designed for families with two primary caregivers and a child age 4 to 17.
Fort Wayne, IndianaAges 4 years+ - NCT05090722Recruiting
PureWick Device for Nighttime Urination in Women
This study tests a device called PureWick that helps manage frequent nighttime urination in women. If you wake up 2+ times per night to urinate, this trial explores whether the device can improve your sleep and quality of life.
New York, New YorkAges 50 years+ - NCT05018663Recruiting
AI test of fluid samples from pancreatic cysts
This trial uses artificial intelligence (AI) to help interpret fluid/scraping samples taken with a needle from pancreatic cysts. You might be eligible if an ultrasound/endoscopy exam found a pancreatic cyst called a PSL and it’s safe for you to have that needle procedure (FNA/FNB).
Houston, TexasAges 18–100 - NCT04026776RecruitingEarly Phase 1
Study hormones and salt sensitivity in adults born preterm
This early-phase study looks at natural body chemicals (uric acid and klotho) and how sensitive your blood pressure may be to salt. It may help researchers understand long-term health risks in people born very early.
Winston-Salem, North CarolinaAges 22–33 - NCT03850418RecruitingPhase 2
Azacitidine for blood chimerism changes after transplant
This Phase 2 study tests whether azacitidine can improve outcomes when donor blood “chimerism” starts dropping after an allogeneic stem cell transplant. It’s for people with AML, MDS, MPN, or CMML who are experiencing early warning signs in their blood counts after transplant but without clear relapse in the bone marrow.
Detroit, MichiganAges 18–75 - NCT04582916RecruitingPhase 1
PET scan study of inflammation in major depression
This Phase 1 study uses a PET brain scan to look at inflammation-related activity (cyclooxygenase) in people with major depressive disorder (MDD). It may help researchers better understand how depression is connected to inflammation in the brain.
Bethesda, MarylandAges 18–70 - NCT03869814Recruiting
Blood test to study cancer signals without invasive procedures
This study looks at a non-invasive blood test to detect cancer-related “signal patterns” and see how well they match different types of cancer. It may help researchers learn better ways to find or understand cancer using less invasive testing.
San Diego, CaliforniaAges 21–80 - NCT04284839RecruitingPhase 3
Blood thinner pills vs warfarin after heart surgery
This trial compares two ways to prevent blood clots after open heart surgery: a “direct oral” blood thinner pill versus warfarin (a vitamin K antagonist). It may help find the safest and most effective option for people who develop atrial fibrillation after surgery.
Fitzroy, VictoriaAges 18 years+ - NCT04017286Recruiting
Pregnancy mental health survey and baby development outcomes study
This study looks at how a pregnant person’s mental well-being during pregnancy relates to their child’s later behavior and development. It mainly involves questionnaires and comparing outcomes, and it may help researchers understand what pregnancy mental health supports best.
Chongqing, Chongqing MunicipalityAges 3 months–6 years - NCT04004364Recruiting
Research study for people enrolled in a schizophrenia care program
This is an early-stage research study for people who are already enrolled in a specific schizophrenia care program. It aims to improve outcomes by testing practice changes within that program.
Lauderdale Lakes, FloridaAges 15–40 - NCT04623424Recruiting
Study gut bacteria during stem cell transplant
This study looks at changes in your gut bacteria (microbiome) around the time of stem cell transplant. The goal is to understand how these bacteria relate to transplant outcomes, which may help doctors improve care in the future.

Ages Any age - NCT04104126Recruiting
Blood flow restriction therapy for an Achilles injury
This trial looks at whether “blood flow restriction” during exercise can improve healing for people with an Achilles injury. You may be asked to also do standard physical therapy, but the study focuses on the added blood-flow-restriction approach.

Common questions
- Are there clinical trials for health?
- Yes. Clin2 currently lists 5,542 recruiting health 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 health 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 health 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.
