Rabies vaccine safety trial for ages 10 to 60
This trial tests a freeze-dried rabies vaccine to see how safe it is when given on different schedules. It may be an option for people who need protection from rabies.
Xuzhou, JiangsuAges 10–60 - NCT05995015RecruitingPhase 1
CD19-targeting T cells for B cell cancers
This trial tests a new type of immune cell therapy (4SCAR19U T cells) designed to attack B-cell cancers. It may be an option if your cancer has the CD19 protein and you haven't had a prior CAR-T treatment that failed.
Shenzhen, GuangdongAges 6 months–75 years - NCT06279104Recruiting
Comparing treatments for ovarian clear cell carcinoma
This study compares different ways to treat ovarian clear cell carcinoma, a rare type of ovarian cancer. It is for women whose cancer has come back or not gone away after platinum chemotherapy, or those newly diagnosed.
Wuhan, HubeiAges 18–75 - NCT05545371Enrolling by invitationPhase 3
Rabies prevention vaccine shots for ages 10 to 60
This trial tests whether giving four rabies vaccine doses can prevent rabies infection. You may be able to join if you’re in the right age range and have no history of rabies vaccine or certain immune system conditions.
Changchun, JilinAges 10–60 - NCT05915442RecruitingPhase 2
Adenosine blocker plus immunotherapy for limited prostate spread
This Phase 2 study tests a medicine that affects “adenosine” signaling along with an immune checkpoint inhibitor (immunotherapy) in men with hormone-sensitive prostate cancer that has spread in only a small, limited way. It aims to stop or slow that limited spread by helping the immune system work better.
New York, New YorkAges 18–99 - NCT05101070RecruitingPhase 1/Phase 2
Study of an anti-cancer drug alone or with immunotherapy
This Phase 1/2 study tests a new cancer drug (S-531011) in people with advanced or metastatic solid tumors, either by itself or combined with an immunotherapy drug. It may help shrink tumors and learn how the treatment works, but it also requires extra procedures like repeat tumor biopsies and frequent monitoring.
Los Angeles, CaliforniaAges 18 years+ - NCT07011238Recruiting
Memory B cells and anti-HLA antibodies in kidney transplant patients
This study looks at how memory B cells (a type of immune cell) relate to antibodies against HLA in people waiting for a kidney transplant. It aims to better understand immune responses, which could help improve transplant matching and outcomes.
RouenAges 18 years+ - NCT06779201Recruiting
Fasting and its effects on metabolism and immunity
This study looks at how fasting affects your body's metabolism and immune system. It may help researchers understand if planned periods of not eating can improve health.
BeijingAges 18–65 - NCT06745102Recruiting

Long-term safety and effectiveness of leniolisib for immune problems
This study tests the long-term safety and effectiveness of the drug leniolisib for people with certain immune system disorders. It is for people who have already been in a previous study of this drug and may benefit from continuing treatment.

Common questions
- Are there clinical trials for immunization?
- Yes. Clin2 currently lists 1,022 recruiting immunization 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 immunization 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 immunization 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.
