Recruiting studies
- NCT06985420Recruiting

Orange, CaliforniaAges 18 years+ - NCT05708508RecruitingPhase 3
Immune-guided vs universal medicine to prevent CMV after kidney transplant
This study compares two strategies to prevent a viral infection called CMV after kidney transplant. It tests whether an “immune-guided” approach (using your immune test results) can prevent CMV as well as or better than giving preventive antiviral medicine to everyone.
RouenAges 18–75 - NCT06708507Recruiting
Immune cells in graft-versus-host disease
This study looks at special immune cells in the body that may be involved in graft-versus-host disease (GVHD), a complication after a stem cell transplant. The goal is to better understand these cells to improve future treatments for GVHD.
Guangzhou, Other (Non U.s.)Ages 18–65 - 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.

Hydroxychloroquine plus prednisone for ANA-positive ITP
This study tests whether a combination of hydroxychloroquine (HCQ) and prednisone (a steroid) is safe and effective for treating immune thrombocytopenia (ITP) in people who have a positive ANA blood test. It may be an option for those with low platelets and bleeding risk.
Shanghai, Shanghai MunicipalityAges 15–99 - NCT07203365RecruitingPhase 3
RSV vaccine study for older adults in Sweden
This study tests a vaccine called Arexvy to see if it protects older adults from RSV, a virus that can cause serious lung infections. You must be born between 1965 and 1960 or before 1945, live in Sweden, and be medically stable.
SaltsjöbadenAges 60 years+ - NCT05584397Enrolling by invitation
Compare immune activity and HIV hidden reservoir on two treatments
This study compares how active the immune system is and how large the “hidden” HIV reservoir is in people on two different HIV treatment types. It may help researchers understand whether staying on a tenofovir-containing regimen leads to better control of HIV hiding in the body.
Seattle, WashingtonAges 18–65 - NCT06479317Recruiting
Combining hydroxychloroquine and dexamethasone for ITP with positive ANA
This trial tests if adding hydroxychloroquine (HCQ) to the steroid dexamethasone (DEX) works better than dexamethasone alone for adults with immune thrombocytopenia (ITP) who have a positive antinuclear antibody (ANA) blood test. The goal is to see if this combination can safely raise platelet counts and reduce bleeding risk.
Shanghai, Shanghai MunicipalityAges 15–75 - NCT06998264Recruiting
Immune response to flu in young children
This study looks at how children's immune systems fight the flu in the nose and throat. It aims to understand why some children get very sick and others don't, which could help create better treatments and vaccines.
GenevaAges 2–5 - NCT07430579Recruiting
Adebrelimab with chemo for esophageal cancer
This trial tests adding adebrelimab (an immunotherapy drug) to standard chemotherapy for people with a type of esophageal cancer called squamous cell carcinoma. The goal is to see if this combination helps shrink tumors before surgery.
JinanAges 18–80 - NCT07400536RecruitingPhase 3
Cadonilimab plus chemo and radiation for advanced cervical cancer
This trial tests a new immunotherapy drug, cadonilimab, combined with standard chemotherapy followed by chemoradiation for locally advanced cervical cancer. The goal is to see if this combination works better than current treatments.
Wuhan, HubeiAges 18–70 - NCT06928233Recruiting
TNF gene study in immune TTP patients
This study looks at a specific gene (TNFAIP3) in people who have had immune-mediated thrombotic thrombocytopenic purpura (iTTP). It aims to understand how this gene might be linked to the condition. Participants will provide a blood or DNA sample for genetic testing.
MilanAges 12 years+ - NCT05568212RecruitingPhase 2
Trial of immune combination versus standard care for NSCLC relapse
This Phase 2 trial studies an immune-based drug combination compared with standard care for lung cancer that has come back after chemoradiation and durvalumab. It aims to improve control of the cancer after durvalumab is no longer working.
Roma, RMAges 18 years+ - NCT07379151Recruiting
Long-term protection from a meningococcal vaccine
This study checks whether the MenFive™ vaccine still protects against meningococcal disease more than five years after vaccination. It aims to see how long the immune response lasts.
BamakoAges 7–36 - NCT07364305RecruitingPhase 2
Hepatic artery infusion + immunotherapy for advanced bile duct cancer
This trial tests combining a liver-directed chemotherapy infusion (HAIC) with immunotherapy to shrink advanced bile duct cancer that cannot be removed surgically. The goal is to slow tumor growth and improve survival.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT04908566RecruitingPhase 2
PD-1 immunotherapy plus chemotherapy before and after gastric surgery
This trial studies whether adding a PD-1 immune therapy to chemotherapy around the time of surgery can improve outcomes for people with locally advanced stomach or stomach–esophagus junction cancer. It aims to better control the cancer before and reduce the chance it comes back after surgery.

Common questions
- Are there clinical trials for immunization?
- Yes. Clin2 currently lists 1,011 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.
