Los Angeles, CaliforniaAges 18 years+ - NCT04973579Recruiting
Stent plus heart surgery for high risk carotid patients
This trial looks at whether doing carotid artery stenting at the same time as heart surgery is safe and effective for people at high risk of stroke around the time of surgery. It targets people with significant carotid narrowing who also need heart surgery for specific heart problems.
KrakowAges 18 years+ - NCT05023369RecruitingPhase 4
Hip replacement patients may get an added steroid injection
This trial tests whether a steroid injection placed around the hip after hip replacement can reduce pain and shorten hospital stay. It is meant for older adults who are having hip replacement due to a broken femoral neck bone.
LuganoAges 50–90 - NCT05045066RecruitingEarly Phase 1
Vitamin D treatment study for Black men with prostate cancer
This early-phase study looks at how vitamin D replacement affects the immune system in Black/African American men with prostate cancer. It’s testing whether bringing vitamin D levels into a healthier range changes immune signals that may matter for cancer health.
Scottsdale, ArizonaAges 18 years+ - NCT05100966Recruiting
Exercise program for people waiting for hip or knee replacement
This trial tests a “getting fit” program to help people who are somewhat frail before hip or knee replacement surgery. It aims to improve fitness while you wait for surgery, which may help you feel stronger for recovery.
Calgary, AlbertaAges 60 years+ - NCT05120492Recruiting
Program for severe knee arthritis and extreme weight
This feasibility study tests a practical approach to help people with very severe knee arthritis and very high body weight. It aims to find an effective and safe way to manage both conditions together in real-world care.
Halifax, Nova ScotiaAges 18–65 - NCT05125822Recruiting
Study of how bodies change weight in youth with obesity
This study looks at what helps or drives weight changes in children and teens with obesity. You may be asked about growth and body changes to better understand why weight changes happen and how to manage them.
Chicago, IllinoisAges 11–15 - NCT05235555Recruiting
TAVI registry for people with severe aortic valve disease
This registry follows people with severe aortic valve narrowing (and sometimes a worn-out valve) who are considered good candidates for TAVI, a valve-replacement procedure. It helps doctors better understand outcomes and care over time.
NaplesAges 55–100 - NCT05275608Recruiting
Low-carb diet effects in people with metabolic syndrome
This trial studies whether a very low-calorie, low-carb diet (VLCKD) can improve metabolic health in adults with metabolic syndrome, fatty liver, and type 2 diabetes. It may help lower blood sugar and improve related health markers if you fit their specific diabetes and liver/kidney criteria.
Novara, ItalyAges 25–65 - NCT05294367RecruitingEarly Phase 1
Magnesium by diet or skin lotion for people with lymphoma
This early study tests whether replacing magnesium—either by diet or a topical (skin) supplement—can improve safety or other health measures in people with lymphoma. It focuses on people who have a slightly low magnesium level and checks blood magnesium repeatedly during the study.
Rochester, MinnesotaAges 18 years+ - NCT05355272RecruitingPhase 2

Common questions
- Are there clinical trials for replacement?
- Yes. Clin2 currently lists 505 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.
