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.

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.

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.
