This study uses a treadmill or stationary bike test to measure how well your heart and lungs work after a heart transplant. It may help researchers see whether this type of testing is safe and useful in transplant follow-up.
Dallas, TexasAges 18 years+ - NCT05451979Recruiting
Exercise training at home for kids after heart transplant
This trial tests a home-based, short bursts exercise program (HIIT using the MedBIKE™ system) for children who had a heart transplant at least 6 months ago. It may help improve fitness and safety after transplant, while checking which kids can participate without heart rhythm or symptom problems.
Edmonton, AlbertaAges 10–18 - NCT06578520RecruitingPhase 4
Testing dapagliflozin for heart failure on dialysis
This trial tests whether adding dapagliflozin (a medication that helps protect the heart and kidneys) helps people with heart failure who are also on peritoneal dialysis. It may offer extra support for your heart and kidney health.
ValenciaAges 18 years+ - NCT07053462RecruitingPhase 1/Phase 2
Gene-edited kidney transplant to lower rejection risk
This trial tests a specially edited donor kidney designed to reduce the chance of rejection, especially for people with high sensitivity to donor kidneys. If it works, it could make more kidneys available for those who have a hard time finding a match.
Beijing, ChangpingAges 16–85 - NCT01757730Recruiting
MRI test to measure soft tissue stiffness
This trial uses a special type of MRI to estimate how stiff certain soft tissues are in the body. You may benefit by helping doctors better measure tissue stiffness, which can relate to different health problems.
Columbus, OhioAges 18 years+ - NCT07531966Recruiting
Blood Vessel Problems After Kidney Transplant Treatment
This study looks at treating narrowing or blockage of blood vessels in transplanted kidneys. If your transplanted kidney is showing signs of not working well and imaging shows a blocked vessel, this trial tests whether a procedure called angioplasty (opening the vessel with a tiny balloon) can help restore blood flow and improve kidney function.
AarhusAges 18 years+ - NCT05374291Enrolling by invitationPhase 3
Dapagliflozin trial for kidney and heart outcomes in severe CKD
This study tests whether dapagliflozin can improve kidney and heart-related outcomes in people with severe chronic kidney disease (CKD). You would take the study medicine (or a comparison treatment) and be followed to see how your kidneys and heart do over time.
Canberra, Australian Capital TeritoryAges 18 years+ - NCT05285878Enrolling by invitationPhase 2
Fingolimod to protect kidney function after kidney transplant
This trial tests whether fingolimod can reduce kidney scarring and preserve kidney function after a new kidney transplant. It focuses on people who are in the early period after transplant who may be at risk for scarring in the kidney.
Houston, TexasAges 18–65 - NCT06532890Recruiting
Using microRNAs to personalize heart transplant medicines in children
This study is looking at heart transplant children (up to age 18) to see if measuring tiny molecules called microRNAs in the blood can help doctors personalize anti-rejection medicines. It aims to improve how we prevent rejection while reducing side effects.
Aurora, ColoradoAges Up to 18 years - NCT07053488RecruitingPhase 1/Phase 2
Gene-edited liver transplant to lower rejection risk
This trial tests a liver transplant using a donor organ that has been gene-edited to reduce the risk of rejection. It may help people who need a liver transplant and are not a perfect tissue match with their donor.
Beijing, ChangpingAges 16–85 - NCT06939751Recruiting
Testing microRNA levels to personalize heart transplant care
This trial is studying whether a blood test that measures small molecules called microRNAs can help doctors personalize the medicines used to prevent rejection after a heart transplant. If you qualify, you would help researchers learn how to better match immunosuppression to each patient's needs.
Los Angeles, CaliforniaAges 18–99 - NCT05525507RecruitingPhase 1
Test early immune-tolerance treatment for matched kidney transplant patients
This Phase 1 study tests a treatment plan given after a kidney transplant to help the immune system stay calm and reduce the risk of rejection. Participants must have a well-functioning kidney transplant from a closely matched living donor and meet health and safety requirements.
Los Angeles, CaliforniaAges 18 years+ - NCT06676696RecruitingPhase 4
Stopping immunosuppression after failed kidney transplant
This study compares what happens when patients with a failed kidney transplant (still in the body) stop their immunosuppressant medicines at 6 months versus continuing them. The goal is to safely prevent your immune system from becoming too sensitive, which can make finding a new donor kidney harder.
BarcelonaAges 18 years+ - NCT03707262RecruitingPhase 1/Phase 2
Brother or sister donor transplant using kidney and stem cells
This study tests a combined approach for kidney transplant patients: standard living-donor kidney transplant plus an added “stem cell” component taken from the same sibling donor. It aims to improve transplant outcomes by trying to better control the immune response and reduce complications.
Los Angeles, CaliforniaAges 18 years+ - NCT07046910RecruitingPhase 2
MRI to detect lung rejection after transplant
This study uses a special MRI scan (called hyperpolarized gas MRI) to check for signs of lung rejection after a transplant. The goal is to see if the MRI can help detect rejection earlier and more safely than standard bronchoscopy alone.
Charlottesville, VirginiaAges 18–80 - NCT06400771RecruitingPhase 1
Safety of DNP007 in Healthy Volunteers
This study tests the safety of a new drug called DNP007 in healthy volunteers. It is a Phase 1 trial, meaning it's one of the first steps in humans to see if the drug is safe and how the body handles it.
SeoulAges 19–55 - NCT06918990RecruitingPhase 1
CarBel for antibody-mediated rejection after kidney transplant
This study tests a new drug called CarBel to treat antibody-mediated rejection in kidney transplant patients. The goal is to see if it can help stop the rejection and protect your new kidney.
Birmingham, AlabamaAges 18–75 - NCT06801886Enrolling by invitationPhase 3
