Munich, BavariaAges 50 years+ - NCT03629977Recruiting
Timing dialysis in critically ill ICU patients
This study looks at the best timing for starting kidney support treatment (dialysis) in very sick people in the ICU. It may help improve outcomes by comparing different start times.
StockholmAges 18 years+ - NCT03900286Recruiting
Testing a low-calorie diet for partial fat loss diabetes
This trial studies whether a low-calorie (low energy) diet can improve diabetes control in adults with familial partial lipodystrophy. It likely helps by changing how your body handles blood sugar and fat use, but you must meet specific safety and eligibility checks.
CambridgeAges 18–99 - NCT03966716Recruiting
Hip screws or hip replacement for small hip fractures
This study compares two treatments for certain small, stable hip fractures in older adults: using hip screws versus replacing part or all of the hip. It may help find which option works best for healing and returning to movement.
Uppsala, Uppsala CountyAges 75 years+ - NCT03991728Recruiting
TMJ implant registry for adults with a new jaw joint replacement
This registry is for adults getting an artificial (alloplastic) full replacement of the jaw joint (TMJ). It collects real-world information about your implant and care to help improve future outcomes.
São PauloAges 18 years+ - NCT04029363Recruiting
Transcatheter mitral valve procedure for high-surgery-risk patients
This trial studies a newer, catheter-based mitral valve treatment in people with moderate-severe to severe mitral valve leaking who are at high risk for open-heart surgery. It may help improve symptoms and heart function without traditional surgery, but you must meet key heart, anatomy, and safety requirements.
Darlinghurst, New South WalesAges 18 years+ - NCT04049331RecruitingPhase 2
Testosterone therapy for cancer survivors with fatigue
This trial tests whether testosterone replacement can help male cancer survivors who have ongoing fatigue and low testosterone levels. It is for men who have completed chemotherapy or radiation and are cancer-free for at least a year.
Boston, MassachusettsAges 18–54 - NCT04073420Recruiting
Cardiac surgery registry to track Medtronic device outcomes
This registry collects real-world information from people who have had—or plan to have—an eligible Medtronic cardiac surgery device. It aims to better understand how these treatments do over time and help guide future care.
Marietta, GeorgiaAges Any age - NCT04084132Recruiting
Testing earlier vs later valve replacement after repaired Tetralogy
This study compares doing a valve replacement earlier versus later in people born with Tetralogy of Fallot who already had heart surgery as babies. It may help decide the safest timing to protect heart function, especially right-sided pumping and valve leakage.
AarhusAges 12 years+ - NCT04121780RecruitingPhase 2
Growth hormone treatment for retired NFL players with low hormone
This Phase 2 study tests whether growth hormone replacement helps retired professional football players who have been diagnosed with growth hormone deficiency. You may be considered if you meet age and health requirements and have the specific hormone diagnosis.
Dearborn, MichiganAges 18–76 - NCT04139616Recruiting
Testing a planned heart rhythm plan after aortic valve replacement
This study tests an algorithm—a step-by-step plan—for how doctors manage abnormal heart rhythms after transcatheter aortic valve replacement (TAVR). It may help guide safer, more consistent care in the weeks after the procedure.
Québec, QuebecAges 18 years+ - NCT04146376Recruiting
Study of medicines for Von Willebrand disease during pregnancy
This study looks at how well a Von Willebrand disease treatment plan works during pregnancy, and whether some patients need extra “adjusting” of medicine. It may help prevent bleeding problems by matching treatment to each person’s lab results later in pregnancy.
Aurora, ColoradoAges 18 years+ - NCT04167033Recruiting
Checking heart rhythm timing in women with premature ovarian insufficiency
This study measures how quickly the heart “recharges” between beats (often shown as QT timing). It compares women with premature ovarian insufficiency to healthy women to understand whether ovarian insufficiency is linked to heart rhythm differences.
BordeauxAges 18–40 - NCT04195984Recruiting
Heart valve replacement through a catheter for leaky mitral valve
This trial studies a new way to replace a damaged mitral heart valve using a catheter (a thin tube), instead of open-heart surgery. It may help people who have severe leaking of the mitral valve but are considered too high-risk for surgery.
Beijing, Beijing MunicipalityAges 65 years+ - NCT04258488RecruitingPhase 4
Blood thinner pill vs warfarin after mechanical aortic valve
This study compares a blood thinner pill (a factor Xa inhibitor) with warfarin (vitamin K antagonist) in people who have had a mechanical aortic valve replacement. It looks at which option works better and is safer over the long term.
Bucheon-siAges 19 years+ - NCT04275362Recruiting
Walking analysis after a specific knee replacement design
This study looks at how people walk after receiving a particular total knee replacement design. It compares movement patterns (gait analysis) to help understand how well the knee works in real life.
Phoenix, ArizonaAges 50 years+ - NCT04281056Recruiting
Tooth loss and dentures: taste and food preferences
This study looks at how losing teeth and wearing dentures affects your mouth sensations and your food choices. It compares people who are fully without teeth (and use dentures) with people who still have their natural teeth.

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.
