Recruiting studies in California
- 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.
Los Angeles, CaliforniaAges 18–75 - 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+ - 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+ - 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+ - 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+ - 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 - 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 - 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 - NCT06263426Recruiting
Kidney transplant from donors with HIV: impact on rejection and long-term results
This study tests whether kidney transplants from donors with HIV are safe and effective for people with HIV who need a new kidney. It looks at long-term outcomes like rejection and survival.
Sacramento, CaliforniaAges 18 years+ - NCT07444489Enrolling by invitationPhase 3
Long-term safety of felzartamab for kidney transplant rejection
This study checks the long-term safety of felzartamab for people who have had a kidney transplant and are dealing with antibody-mediated rejection or signs of inflammation in the kidney. It's for those who were already in a previous study and took at least one dose of felzartamab.
Los Angeles, CaliforniaAges 18–75 - 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+ - NCT07219043RecruitingPhase 2
Felzartamab for kidney transplant patients with inflammation
This trial tests a drug called felzartamab to see if it can help people who have a type of kidney inflammation after a transplant, even without donor-specific antibodies. It might offer a new treatment option for those who are not getting better on their own.
Loma Linda, CaliforniaAges 18–74 - NCT04877288RecruitingPhase 3
Switch some teen kidney transplant patients to belatacept
This Phase 3 study tests whether switching teens from one anti-rejection medicine to belatacept works as well as staying on the current regimen. It also looks at safety and whether patients can stay on their anti-rejection medicines.
Los Angeles, CaliforniaAges 12–17 - NCT05896839RecruitingPhase 1/Phase 2
Immunotherapy with prednisone and sirolimus for transplant skin cancer
This early-phase study tests whether adding immunotherapy (nivolumab and ipilimumab) to prednisone and sirolimus can control advanced skin cancers in people with kidney transplants. It aims to see how well the treatment works and how safe it is for transplant recipients.

What taking part in a kidney transplant rejection 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.

Common questions
- Are there kidney transplant rejection clinical trials in California?
- Yes. We're currently tracking 15 recruiting kidney transplant rejection studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a kidney transplant rejection study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a kidney transplant rejection trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
