Heart Transplant clinical trials in California
We’re tracking 15 recruiting heart transplant studies with a site in California — including Phase 1, Phase 2 and Phase 4 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT06428097RecruitingPhase 1
Thyroid hormone before heart transplant
This study tests whether giving a thyroid hormone supplement called levothyroxine before a heart transplant can help with recovery. It is for people already listed for a heart transplant who do not have thyroid problems.
San Francisco, CaliforniaAges 18 years+ - NCT03102125RecruitingPhase 4
Testing causes of heart transplant graft problems with scans
This study looks at why heart transplant “grafts” can start to malfunction again after transplant. If you qualify, you may undergo MRI and related heart testing to help researchers find ways to detect or understand graft dysfunction.
La Jolla, CaliforniaAges 18 years+ - NCT06478017RecruitingPhase 2
Belatacept for heart transplant patients
This study tests whether a drug called belatacept can safely help your body accept a new heart without rejecting it, and may reduce the need for other strong immune-suppressing medicines. If you are getting a heart transplant for the first time and have certain immune markers, this trial may be an option for you.
Los Angeles, CaliforniaAges 18–71 - NCT06895070Recruiting
Heart transplant study using a special preservation machine
This trial tests a special machine that preserves donor hearts for longer periods before transplant. It may help people waiting for a heart transplant who need a heart from a donor that may be older or has some heart risks.
Los Angeles, 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+ - NCT07145515Recruiting
Heart preservation device trial for transplant patients
This trial tests a portable device that keeps donor hearts healthy outside the body before transplant. It may help more donor hearts be used, including those from donors after circulatory death and hearts previously considered less suitable.
San Francisco, CaliforniaAges 18 years+ - NCT05610787Enrolling by invitation
Testing a device that helps move an EXCOR pediatric heart pump
This trial studies an “active driving” system that controls the EXCOR pediatric heart pump. It’s meant for children who need a heart pump as a bridge to heart transplantation, to help the pump work more safely and effectively.
Los Angeles, CaliforniaAges Up to 21 years - NCT05915299Recruiting
Heart surgery donor heart monitoring registry
This is a registry that collects information about how donated hearts are handled using a portable machine that keeps the heart healthy outside the body. It may help researchers improve future care, but it usually does not test a new medication.
La Jolla, CaliforniaAges Any age - NCT03292861Enrolling by invitationPhase 2
Thymoglobulin after first heart transplant: safety and effect
This trial tests whether Thymoglobulin® is safe and how well it works in people getting their first heart transplant. It may help doctors fine-tune medicines used to prevent the body from rejecting the new heart.
Los Angeles, CaliforniaAges 18–70 - NCT02670408Recruiting
Microarrays test in heart transplant care
This study checks how special lab tests on heart tissue samples can help guide diagnosis and treatment for people with a heart transplant. You may be eligible if you already need a heart tissue biopsy for a clinical reason and can provide consent.
Los Angeles, 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+ - NCT05933083Recruiting
In-person vs telehealth heart rehab comparison study
This study compares whether heart rehabilitation done in person or by telehealth (video/phone) works as well for people with certain heart conditions. It may help you and others choose the safest and most effective way to receive cardiac rehab.
San Francisco, CaliforniaAges 18 years+ - 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 - NCT06948097RecruitingPhase 1
Testing fostamatinib for lung transplant patients with new donor-specific antibodies
This trial tests a drug called fostamatinib to see if it is safe and tolerable for lung transplant patients who develop new antibodies against their donor lung. It aims to prevent rejection without harming the new lung.
Stanford, CaliforniaAges 18–99 - NCT03383419RecruitingPhase 2
Hepatitis C–safe antiviral plan for heart transplant recipients
This Phase 2 trial tests giving newer hepatitis C medicines in a careful way to people getting a heart transplant who currently do not have hepatitis C in their blood. The goal is to lower hepatitis C infection risk from donated organs while keeping transplant outcomes safe.
Los Angeles, CaliforniaAges 18–90

What taking part in a heart 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.

Common questions
- Are there heart transplant clinical trials in California?
- Yes. We're currently tracking 15 recruiting heart transplant 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 heart transplant 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 heart transplant 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.
Not the right time?
New heart transplant studies open in California regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
