Recruiting studies in California
- NCT07006831Recruiting
Blood study for kidney transplant patients
This study collects blood and leftover donor samples from kidney transplant recipients who need a biopsy. The goal is to improve monitoring after transplant.
San Diego, CaliforniaAges 18 years+ - NCT04954690Recruiting
Exercise program after kidney transplant for older adults
This trial tests a structured, coached exercise program for people who recently received a living-donor kidney and are coming from dialysis. It may help improve strength and daily function after transplant, especially if starting fitness is difficult.
San Francisco, CaliforniaAges 50 years+ - NCT05917522RecruitingPhase 2
Biomarker-guided changes to anti-rejection medicines after kidney transplant
This Phase 2 study looks at whether blood test “biomarkers” can guide safely changing anti-rejection medicines after an ABO-compatible kidney transplant. It may help some people reduce certain medicines while keeping the new kidney protected from rejection.
Los Angeles, CaliforniaAges 18–70 - 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+ - NCT06824454RecruitingPhase 2
Testing dipyridamole to prevent low phosphate after kidney transplant
This trial tests if a drug called dipyridamole can prevent low phosphate levels after a kidney transplant. It is for adult kidney transplant patients who can safely take the drug.
Stanford, CaliforniaAges 18 years+ - NCT07060716Recruiting
Blood test to monitor kidney transplant health
This study is testing a blood test that looks for tiny pieces of the donor's DNA in your blood to check how your new kidney is doing. It may help doctors monitor your transplant and spot problems early, possibly without needing a biopsy.
Los Angeles, CaliforniaAges 18 years+ - NCT03943238RecruitingPhase 1
Kidney transplant with immune therapy to prevent rejection
This trial tests a combination of low-dose radiation, chemotherapy, and donor immune cells to help your body accept a living donor kidney without long-term anti-rejection drugs.
Palo Alto, CaliforniaAges 18–65 - NCT04783441Recruiting
Continuous glucose sensor study after kidney transplant
This study checks whether using a continuous glucose monitor (a sensor that tracks sugar throughout the day) is helpful and practical for people with a recent kidney transplant and type 2 diabetes on insulin. You may need to wear the sensor continuously and still do finger-stick glucose checks for safety.
Sacramento, CaliforniaAges 18 years+ - NCT06337942Recruiting
Bladder or kidney-bladder transplant from a deceased donor
This trial offers a first-in-human transplant of a bladder or a kidney combined with a bladder from a deceased donor. It is for people with severe bladder problems or bladder cancer who already need a new bladder or are on immune-suppressing medicines for a prior organ transplant.
Los Angeles, CaliforniaAges 18–70 - NCT06126380Enrolling by invitationPhase 2
Long-term safety of tegoprubart in kidney transplant patients
This is a long-term follow-up study for people who have already completed a study of the drug tegoprubart after a kidney transplant. It checks how safe and effective the drug is over a longer period.
Orange, CaliforniaAges 18–100 - NCT06798909RecruitingPhase 3
CMV prevention in kidney transplant patients
This trial tests two ways to prevent CMV in kidney transplant patients who are at high risk. It compares giving antiviral medicine preemptively (based on regular blood tests) versus giving it as prophylaxis (starting right after transplant). The goal is to see which approach prevents CMV infection better.
San Francisco, CaliforniaAges 18 years+ - NCT06830798RecruitingPhase 3
Ravulizumab to prevent delayed graft function after kidney transplant
This study tests an investigational medicine (ravulizumab) given through a vein to see if it can prevent delayed graft function—meaning the new kidney takes longer to start working—after a high-risk kidney transplant. It is for adults on dialysis who are getting a kidney from a donor whose heart stopped or who is considered high-risk.
Stanford, CaliforniaAges 18 years+ - NCT06877169Recruiting
Staged heart and kidney transplant study
This study compares two ways of doing a combined heart and kidney transplant. It looks at doing the surgeries in separate stages instead of all at once, to see if that is safer or works better.
Los Angeles, CaliforniaAges 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+ - NCT05508009RecruitingPhase 1/Phase 2
Kidney transplant with donor-matched stem cell treatment
This early-phase trial tests a stem cell transplant from a donor who is an extremely close match, given to people who are about to receive a kidney transplant from the same donor. The goal is to improve how well the new kidney works by resetting the immune system to better accept the transplant.
Palo Alto, CaliforniaAges 1–30 - NCT06919003RecruitingPhase 2
Improving kidney transplant with a single injection of a protective protein
This trial tests whether a single injection of C1 esterase inhibitor into a donated kidney during preservation can improve transplant outcomes. It is for adults on dialysis waiting for a deceased-donor kidney who meet specific blood and tissue matching requirements.
Los Angeles, CaliforniaAges 18–75 - NCT05106387Recruiting
Study follow-up for people who had a kidney transplant
This study follows adults who previously received vonsetamig in an earlier study and then got a kidney transplant while enrolled. It mainly looks at what happens after the transplant and helps doctors understand outcomes over time.
Los Angeles, CaliforniaAges 18–70 - NCT07508787RecruitingPhase 2
Study comparing siplizumab to another drug for kidney transplant acceptance
This trial tests a new drug, siplizumab, to see if it helps the body accept a donated kidney better than a standard treatment. It is for people receiving a kidney transplant from a living or deceased donor.
Sacramento, CaliforniaAges 18–70 - NCT03591302RecruitingPhase 1
Stem cell transplant to stop anti-rejection drugs after kidney transplant
This study tries to use a stem cell transplant from your original kidney donor to help your body accept the kidney without needing lifelong anti-rejection drugs. You must have a perfectly matched sibling donor who is still available.
Palo Alto, CaliforniaAges 18 years+ - NCT06055608RecruitingPhase 2
Improving kidney transplant outcomes in teens and young adults
This trial tests a new approach to help teenagers and young adults keep their first kidney transplant working well. It looks at how to improve long-term success by carefully managing the immune system around the time of transplant.
Los Angeles, CaliforniaAges 13–20 - NCT04571203RecruitingPhase 1
Kidney transplant plus blood-cell treatment to help the graft settle
This Phase 1 study tests a treatment plan (including rabbit medicine and a low dose of radiation) meant to help the new kidney “take” and work longer. It also includes a kidney-from-deceased-donor process and checks how safely the treatment works in people with end-stage kidney disease.
Stanford, CaliforniaAges 18–65 - NCT05084768Recruiting
Test blood markers to predict kidney transplant rejection
This study looks at special blood tests to help predict when kidney transplant rejection might happen. If the markers work, they could help doctors catch rejection earlier and adjust treatment sooner.
Loma Linda, CaliforniaAges 18 years+ - NCT06625073RecruitingPhase 4
SGLT2i for heart transplant recipients
This trial is testing a medication called SGLT2i (a type of diabetes drug that also helps the heart and kidneys) in people who have received a heart transplant. It aims to see if this drug can improve health after transplant.
Palo Alto, CaliforniaAges 18 years+ - NCT06531967Enrolling by invitation
Predicting survival in kidney transplant recipients
This study looks at factors that may help predict how long kidney transplant recipients live. If you are an adult who has received a single kidney transplant (your first one), you may be able to take part.

What taking part in a kidney transplant study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
