Stem cell transplant to rebuild immunity in genetic immune disorders
This Phase 2 trial tests a stem cell (bone marrow) transplant approach to restore bone marrow function and immune function in people with certain inherited immune problems. If you have one of these conditions and a suitable donor, the study may offer a path to rebuild blood and immune systems.
Baltimore, MarylandAges 4 months–50 years - NCT07844616Recruiting
Eggs, gut health, and metabolism study
This study looks at how eating whole eggs versus egg whites affects your gut bacteria, metabolism, and immune system. It aims to understand how eggs may influence health markers in people of different weight ranges.
Storrs, ConnecticutAges 18–50 - NCT07799207Recruiting
Daily yogurt and immune health in healthy adults
This study tests whether eating yogurt every day can help your immune system work better and make you feel healthier overall. You would eat a provided yogurt daily for the study period and attend a few check-ins.
Chicago, IllinoisAges 18–65 - NCT07735221Recruiting
Peanuts for stress and heart health
This trial tests whether eating peanuts every day can reduce stress, improve immune function, and lower inflammation in people who feel stressed. If you are stressed and generally healthy, you may qualify.
Davis, CaliforniaAges 18–65 - NCT00128973Recruiting
Study immune system problems in people with unusual infections
This study looks at how the immune system works in people who have abnormal immune function, often shown by unusual or repeated infections or long-lasting inflammation. It may involve tests using blood samples and storage of blood for future research.
Bethesda, MarylandAges Any age - NCT06737224Recruiting
Fasting and exercise effects on immune health
This study looks at how a 48-hour fast, alone or combined with exercise, affects your immune system and blood sugar control. It may help explain how short-term fasting can improve health in active young adults.
Kelowna, British ColumbiaAges 19–35 - NCT06203249Recruiting
Exploring lung health and immune system in a rare muscle disease
This trial looks at how the immune system and tiny organisms in the lungs may affect a rare condition called anti-MDA5 positive dermatomyositis, which can cause serious lung disease. It may help doctors understand why some patients get worse quickly and how to better treat them.
Beijing, Beijing MunicipalityAges 18–100 - NCT03240328RecruitingPhase 1
CAR-T therapy study for rebuilding HIV immune defenses
This early-stage study tests whether CAR-T cells can help rebuild the immune system’s ability to fight HIV. You may be a candidate if your HIV is well controlled on standard treatment and you don’t have certain serious infections or organ problems.
Guangzhou, GuangdongAges 18–60 - NCT06528977Recruiting

Common questions
- Are there clinical trials for immune function?
- Yes. Clin2 currently lists 48 recruiting immune function 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 immune function 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 immune function 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.
