HRT and fatty liver disease in menopausal women – a pilot study
This study tests whether starting hormone replacement therapy (HRT) improves liver health in women with menopause and fatty liver disease (MASLD). It aims to understand how HRT might help reduce fat in the liver.
Oxford, OxfordshireAges 18 years+ - NCT07243184Recruiting
Polymer heart valve study for mitral valve disease
This trial is testing a new polymer artificial heart valve for people with severe mitral valve problems. It aims to see if this valve is safe and works well during surgical replacement.
BeijingAges 60 years+ - NCT06608823Recruiting
Comparing surgery vs. the Trilogy valve for aortic regurgitation
This trial compares a new less-invasive valve replacement (Trilogy TAVR) with standard open-heart surgery for people with significant aortic regurgitation. It aims to see which treatment works better for patients who are eligible for both procedures.
Burlingame, CaliforniaAges Any age - NCT07158554Recruiting
Emergency department test for muscle damage after a fall
This study looks at patients who come to the emergency department after a fall and have a specific type of muscle injury. Researchers want to learn more about how to quickly identify this injury so doctors can offer the best care.
Westcliff-on-Sea, EssexAges 60 years+ - NCT06714214Recruiting
Predicting when you can stop kidney dialysis
This trial studies whether a blood test called delta C-cistatin can help doctors predict when patients can safely stop continuous kidney dialysis after acute kidney injury.
BolognaAges 18 years+ - NCT06733350RecruitingPhase 4
Testosterone therapy for low testosterone in men with low-risk prostate cancer
This study tests whether testosterone replacement therapy can safely improve low testosterone levels in men with low-risk prostate cancer who are not getting immediate treatment. It aims to help men feel better without worsening their cancer.
Buffalo, New YorkAges 18 years+ - NCT06743568Recruiting
Comparing new valves for tight aortic valve in enlarged aorta
This trial tests two types of replacement heart valves (self-expanding and balloon-expanding) in people who have severe aortic stenosis (tight heart valve) and an enlarged aorta (the main blood vessel from the heart). The goal is to see which valve type works better for these patients.
Beijing, Beijing MunicipalityAges 65 years+ - NCT06750172Recruiting
Shorter salt test for primary aldosteronism diagnosis
This study tests if a 2-day version of the oral salt loading test works as well as the standard 3-day test to diagnose primary aldosteronism (a common cause of high blood pressure). If effective, it could make diagnosis faster and easier for patients.
Beijing, Beijing MunicipalityAges 18–70 - NCT06764719Recruiting

This trial tests if special hair follicles can be used for cell replacement therapy in disease. It may help people with certain medical conditions.
Toronto, QuebecAges 18–80 - NCT06777368Recruiting
Redo TAVR for failed transcatheter aortic valves
This trial tests a second transcatheter aortic valve replacement (TAVR) procedure for patients whose first TAVR valve is failing. It focuses on structural problems inside the valve, not leakage around it.
Birmingham, AlabamaAges 18–105 - NCT06814574Recruiting
Pacemaker after tricuspid valve replacement
This study looks at whether people who need a new tricuspid heart valve also need a pacemaker soon after. Researchers want to learn more about heart rhythm changes after valve replacement.
München, BavariaAges Any age - NCT06818084RecruitingPhase 4
TAVR for severe aortic regurgitation using VitaFlow Liberty
This trial tests the VitaFlow Liberty device, a catheter-based treatment for people with severe aortic regurgitation (a leaky heart valve). If you have symptoms or your heart is starting to weaken, this procedure might help avoid open-heart surgery.
Shanghai, Shanghai MunicipalityAges 60 years+ - NCT06821516Recruiting

Common questions
- Are there clinical trials for replacement?
- Yes. Clin2 currently lists 502 recruiting replacement 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 replacement 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 replacement 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.
