ParisAges 6–8 - NCT04339777RecruitingPhase 2
Bone marrow transplant for inherited immune system disorders
This trial studies how well a donor bone marrow (stem cell) transplant works for people with inherited immune system problems (called immune deficiencies). It’s for patients who haven’t improved with usual treatment or don’t have another good option.
Bethesda, MarylandAges 4–69 - NCT00895271Enrolling by invitation
Making lab cell lines from skin biopsies in immune disorders
This study creates special lab cell lines from skin (or nasal) samples from people with immune system disorders and certain family members. It’s meant to help researchers build tools to better study these conditions using patient cells.
Bethesda, MarylandAges 2–85 - NCT07284641RecruitingPhase 2
Stem cell transplant for immune disorders
This trial tests a stem cell transplant to treat common variable immunodeficiency (CVID) and other immune problems. It aims to replace a faulty immune system with a healthy one from a donor.
Pittsburgh, PennsylvaniaAges 5–40 - NCT04414046RecruitingPhase 2
Stem cell transplant using T-cell cleanup for immune and metabolism disorders
This Phase 2 study tests a specialized stem cell transplant that removes certain “T-cells” (a type of immune cell) to treat children with serious immune system or inherited metabolic problems. The goal is to improve or stabilize disease by resetting the immune system and supporting the body’s function.
St. Petersburg, FloridaAges Up to 21 years - NCT07698197Recruiting
Exercise study for immune system problems
This study tests if a moderate exercise program can help people with certain antibody deficiencies. It aims to see if exercise improves immune function in people who are not taking immunoglobulin therapy.
Milford, ConnecticutAges 18–65 - NCT07261891Recruiting
Lab study of JAK-STAT related disorders
This study looks at blood or tissue samples from people with certain genetic disorders that affect a key cell communication pathway (JAK-STAT). The goal is to learn more about these disorders and test potential treatments in the lab.
Leuven, Vlaams-BrabantAges 18 years+ - NCT07251179Recruiting
Understanding immune cells in autoimmune diseases and immune deficiencies
This study looks at immune cells in people with certain autoimmune diseases or immune deficiencies. The goal is to understand how these cells work, which may help improve future treatments.
StrasbourgAges 18–70 - NCT06839456RecruitingPhase 1/Phase 2
Stem cell addback to prevent infections after transplant
This trial tests whether adding back certain immune cells after a stem cell transplant can help prevent serious viral or fungal infections. It's for children and young adults up to age 25 who need a transplant for a blood cancer or other curable disease.
Philadelphia, PennsylvaniaAges 1 month–25 years - NCT01962415RecruitingPhase 2
Reduced-intensity stem cell transplant for non-cancer disorders
This trial tests whether a gentler (reduced-intensity) conditioning treatment before a stem cell transplant works for non-cancer diseases. It uses specific donor stem cell matches and checks heart, lung, liver, and kidney function to help lower transplant stress while still aiming for benefit.
Pittsburgh, PennsylvaniaAges 2 months–55 years - NCT04864886Recruiting
Study how immune-related conditions affect metabolism
This study collects blood and other samples to see how the immune system changes “metabolism” (how your body uses energy) in people with immune-related conditions. Your samples may also be stored for future research and could help researchers better understand immune health.
Bethesda, MarylandAges 18–75 - NCT04691622RecruitingPhase 1
Treat chronic norovirus using donor immune cells
This Phase 1 study tests whether giving immune cells made from a donor can help children and adults with long-lasting (chronic) norovirus infection. It’s aimed at people whose immune system is weakened after a stem cell transplant, solid organ transplant, or due to primary immune problems.
Washington D.C., District of ColumbiaAges 3 months–80 years - NCT04528355Recruiting
Study of hospital data after stem cell transplant for non-cancer illness
This study collects medical information from people with certain non-cancer conditions who receive a stem cell transplant. It may help doctors better understand transplant outcomes and care, since the study focuses on data collection rather than adding new treatment.
Pittsburgh, PennsylvaniaAges 2 months–60 years - NCT03422614Recruiting

Common questions
- Are there clinical trials for primary immunodeficiency?
- Yes. Clin2 currently lists 24 recruiting primary immunodeficiency 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 primary immunodeficiency 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 primary immunodeficiency 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.
