Autism Treatment Using Stem Cells, Gut Microbiome, and Diet
This study tests whether a combination of stem cell therapy, gut microbiome restoration (using specially prepared stool), and dietary changes can improve autism symptoms, communication, social behavior, and digestive issues. Researchers believe gut health and immune system problems may contribute to autism, and this trial explores whether treating these areas helps.

New immune cells to help stem cell transplant success
This trial tests whether a special type of immune cell (called CD8 regulatory precursors) can help prevent the body from rejecting a stem cell transplant from a donor. It is for patients receiving a stem cell transplant from a related donor.
Beijing, Beijing MunicipalityAges 18–60 - NCT06746077Enrolling by invitation
Lung disease study in children: new ways to understand infections
This study explores how the immune system and lung microbes affect children with lung disease. It uses extra fluid collected during a standard lung exam to look for new treatment targets.
Aarhus NAges birth–17 years - NCT06646263Enrolling by invitation
Immune response study for triple-negative breast cancer
This study looks at how your immune system responds to triple-negative breast cancer. It will test your blood or tissue to learn more about your body's natural defenses against the cancer.
Thessaloniki, ThessalonikiAges Any age - NCT06540027Enrolling by invitation
Minimally invasive surgery for rectal cancer inflammation
This study looks at how different types of surgery (open, laparoscopic, or robotic) affect inflammation throughout the body in people with rectal cancer. It may help doctors understand which approach is gentler on your immune system.
IstanbulAges Any age - NCT06495593Enrolling by invitationPhase 4
Ocrelizumab's effect on immune cells in lymph nodes in MS
This study tests how ocrelizumab, a medication for MS, affects immune cells in your lymph nodes. It may help doctors understand how the drug works and why it helps some people more than others.
San Francisco, CaliforniaAges 18–65 - NCT06484686Enrolling by invitationPhase 4
Long-term immunity study of chickenpox vaccine booster
This study follows up people who were in a previous phase 3 chickenpox vaccine trial. It checks how long protection from a booster dose lasts, by taking a blood sample.
Zhengzhou, HenanAges 8–16 - NCT06401720Enrolling by invitation
Flu immune response study by age
This study looks at how the immune system reacts to the flu in people of different ages. If you have flu symptoms and don't have cancer or take immune-suppressing drugs, you may be able to join.
SödertäljeAges 18 years+ - NCT06332131Enrolling by invitation
Heart blood vessel effects of immunotherapy in breast and lung cancer
This trial studies whether immunotherapy drugs (called immune checkpoint inhibitors) affect the small blood vessels of the heart. If you have breast cancer or lung cancer and are starting a specific treatment plan, you may be asked to have a special heart scan before and during therapy.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06133530Enrolling by invitation
Human milk sugars for gut health in Antarctica
This study tests whether natural sugars found in human milk (called HMOs) can improve gut health and the immune system. Researchers are looking for healthy adults who are willing to travel to Antarctica for the study.
ErfurtAges 18–65 - NCT05654883Enrolling by invitation
Study of mpox immunity in people who were vaccinated or infected
This observational study looks at how your body’s defenses work against mpox (monkeypox), based on blood and health information. You may be eligible if you recently got an mpox vaccine or have had mpox infection and are now out of isolation.

Immune study in MS and healthy adults using a special tube
This study compares immune (defense system) “profiles” between people with multiple sclerosis (MS) and healthy volunteers. It involves a thoracic duct cannulation procedure and several MRIs to see how immune cells behave and whether a specific immune pattern is different in MS.
Philadelphia, PennsylvaniaAges 18–40 - NCT05131594Enrolling by invitation

Study tracks lasting protection from a live chickenpox vaccine
This trial follows people who previously took a chickenpox (varicella) vaccine to see how long their immune protection lasts. It may help explain who stays protected over time and for how long.

Rituximab for OCD or psychosis linked to immune inflammation
This trial tests rituximab (an immune system medicine) to see if it can reduce OCD symptoms and/or psychosis when there are signs the immune system may be involved. You may be considered if other standard psychiatric treatments have not helped enough and your illness seems relatively recent with possible inflammation clues.

Common questions
- Are there clinical trials for immunization?
- Yes. Clin2 currently lists 1,057 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.
