This study gathers information about healthcare workers (adults) and tracks your past COVID-19 infection and vaccination history. It may help researchers understand how COVID affects healthcare workers and how vaccines relate to infection outcomes.
DüsseldorfAges 18 years+ - NCT05584267RecruitingPhase 2
Immunotherapy plus targeted brain radiation for lung cancer
This Phase 2 trial studies whether giving immunotherapy along with a precise form of brain radiation can control brain metastases from non-small cell lung cancer. It may help by shrinking or stabilizing spots in the brain while your body’s immune system is also activated.
Changsha, HunanAges 18 years+ - NCT05586360RecruitingPhase 2
Testing how a statin may change immune markers in prostate cancer
This Phase 2 study tests whether taking simvastatin can change “immune regulation” markers in men with intermediate- to high-risk localized prostate cancer. It also looks at whether this could help lower the risk of cancer coming back after planned prostate surgery.
Atlanta, GeorgiaAges 18 years+ - NCT05591924Recruiting

London, OntarioAges 18 years+ - NCT05598879Recruiting
New heart-cancer visit registry for adults
This study is a “registry,” meaning it collects health information from adults who are getting a new heart (cardio) evaluation related to cancer. It helps doctors better understand heart risks and care needs for different cancer types and treatments.
Weston, FloridaAges 18 years+ - NCT05606341RecruitingPhase 1
Testing a diabetes-style shot to boost brain immunity in early Alzheimer’s
This Phase 1 study tests whether stimulating the immune system (through a receptor called TLR9) is safe and may affect brain changes in people with early Alzheimer’s. It mainly enrolls older adults with memory impairment confirmed by specific amyloid imaging.
New York, New YorkAges 60–85 - NCT05616546RecruitingPhase 4
Study of immune responses during and after flu infection
This study looks at how your immune system (your body’s infection-fighting system) responds during and around the time of a flu illness. It’s meant to help researchers better understand immune changes in healthy adults and may guide future flu care.

Blood-marker guided add-on treatment for major depression
This study tests whether doctors can choose the best add-on immune-related treatment for people with major depressive disorder by using inflammation blood tests. It’s meant for people whose depression has not improved enough with their current antidepressant.
Duffel, AntwerpenAges 18–65 - NCT05652608Recruiting
Psoriatic arthritis wellness survey for adults in the US
This study is looking at how people living with psoriatic arthritis (PsA) are doing through a wellness survey. If you live in the US or Puerto Rico, have PsA, and are taking prescribed PsA medicine, you may be able to share your experience through online questionnaires.
Upper Nyack, New YorkAges 19 years+ - NCT05670158Recruiting
Testing blood immune markers after cochlear implantation
This study compares blood and fluid-related immune “profiles” after cochlear implant surgery versus another ear/middle-ear surgery group. It aims to learn which immune signals may be linked to hearing outcomes and recovery after implantation.
MontpellierAges 18 years+ - NCT05694325Recruiting
Studying biologic features in adults with newly diagnosed ITP
This study looks at blood and immune system patterns in adults with primary immune thrombocytopenia (ITP) who are starting their first treatment. The goal is to better understand what’s happening in ITP, which may improve how future patients are cared for.
BolognaAges 18 years+ - NCT05711992Recruiting
Registry for rare brain embryonal tumors in children and teens
This study is an international registry (a way to collect medical information) for people with certain rare brain tumors, diagnosed since 2010. It helps researchers understand these tumors better, which can guide future treatments.
YerevanAges 1 day–25 years - NCT05715229RecruitingPhase 2
Blood test–guided treatment choice for advanced lung cancer
This Phase 2 study tests how results from blood cancer DNA tests (ctDNA) can help choose the best immune therapy approach for newly diagnosed, advanced lung cancer. It aims to improve outcomes by matching treatment decisions to a patient’s immune and blood test “profile.”
Washington D.C., District of ColumbiaAges 18 years+ - NCT05726786RecruitingPhase 3
Immunonutrition before bladder removal surgery
This study tests whether a special nutrition drink given before open bladder surgery can reduce complications and improve the body’s immune response after surgery. It’s for adults having bladder removal and is compared against standard care.
Lausanne, Canton of VaudAges 18 years+ - NCT05736419RecruitingPhase 2
Immune-suppressing treatment before stem cell transplant for blood disorders
This Phase 2 study tests an immune-suppressing treatment for people with sickle cell disease or beta-thalassemia who are preparing for a stem cell transplant from a donor. It aims to help the transplant work better by changing the immune response.
Basking Ridge, New JerseyAges 2–50 - NCT05739045RecruitingPhase 2
Nivolumab plus SOX before and around stomach cancer surgery
This Phase 2 trial tests whether adding nivolumab to standard chemotherapy (SOX) given before and around surgery can improve outcomes for people with certain stomach or stomach–esophagus junction cancers. It aims to shrink or control the cancer and make surgery more effective.
Hangzhou, ZhejiangAges 18–80 - NCT05743582Recruiting
Studying natural immunity in COPD and in healthy adults
This study looks at how the body’s “innate” (first-line) immune system works in people with COPD compared with healthy volunteers. It may help researchers understand COPD inflammation and how immune responses could be targeted in the future.
EdinburghAges 18–77 - NCT05751447Recruiting
Studying immune cells in suspected sarcoidosis
This study looks at immune cells in the lungs, lymph nodes, and blood to learn more about suspected sarcoidosis. You may benefit by helping researchers better understand the condition and by getting close medical evaluation as part of the study.
StockholmAges 18–90 - NCT05754203Recruiting
Radiation plus immunotherapy for advanced lung cancer
This trial studies whether a more intensive form of targeted radiation, combined with immunotherapy (immune checkpoint inhibitors), can work better and be safe for people with advanced non-small cell lung cancer. You may be considered if your tumor is limited in size and you’re able to receive both treatments.
Chongqing, Chongqing MunicipalityAges 18–75 - NCT05766410RecruitingPhase 2
Testing three CDK4/6 pills to change the immune response
This phase 2 trial compares ribociclib, palbociclib, and abemaciclib to see how each one affects your body’s immune response in estrogen- and/or progesterone-receptor–positive, HER2-negative early breast cancer. If you fit the stage and health requirements, joining could help doctors learn which treatment best “modulates” the immune system.
TaipeiAges 20 years+ - NCT05768035RecruitingPhase 1/Phase 2
Testing SMART101 after half-matched stem cell transplant
This trial studies a new immune treatment called SMART101 given after a half-matched (haploidentical) stem cell transplant that uses post-transplant cyclophosphamide to prevent complications. It mainly checks safety, and may also look at how well SMART101 helps people with blood cancers recover after transplant.
MarseilleAges 18 years+ - NCT05772611Recruiting
Study of immune responses in brain autoimmune and nerve syndromes
This study looks at how the immune system works in certain neurological conditions, including autoimmune encephalitis and related nerve disorders.

Common questions
- Are there clinical trials for immunization?
- Yes. Clin2 currently lists 1,069 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.
