Recruiting studies
- NCT05405491Recruiting
DNA test to guide antibiotic use for pneumonia in ICU patients
This study tests whether using a DNA test on lung fluid can help doctors choose better antibiotics for pneumonia in ICU patients with weakened immune systems. It may lead to more effective treatment and fewer side effects.
LilleAges 18 years+ - NCT05193552RecruitingPhase 4
Spirometry study for people with CVID on IG therapy
This trial looks at how breathing tests (spirometry) can help guide treatment decisions for people with CVID and airway disease who are already on immune globulin (IG) therapy. It may help your care team better monitor lung function using a specific breathing-test pattern.
Birmingham, AlabamaAges 21 years+ - NCT05183854RecruitingPhase 2
Vaccine study for CLL patients to prevent pneumococcal infections
This trial tests a series of two pneumococcal vaccines (PCV20 and PPSV23) in people with CLL-related immune weakness. It aims to see how well the vaccines work and how safe they are for preventing serious lung infections.
Salt Lake City, UtahAges 18 years+ - NCT05027945RecruitingPhase 2
Stem cell transplant for people with VEXAS syndrome
This Phase 2 trial tests whether an allogeneic stem cell transplant (from a donor) can treat VEXAS syndrome. It may help calm the body’s overactive inflammation and improve symptoms in eligible adults.
Bethesda, MarylandAges 18–75 - NCT04943861Recruiting
Study on HIV and food insecurity support
This study is looking at food insecurity in adults living with HIV. It may help improve understanding of the barriers to healthy living and guide better support for people affected by HIV.
Winston-Salem, North CarolinaAges 18 years+ - NCT04958122RecruitingPhase 3
Antibiotic treatment trial for early syphilis
This Phase 3 study tests whether cefixime can treat primary, secondary, or early latent syphilis. It may help by offering another effective antibiotic option, including for some people who also have HIV (if well controlled).
Los Angeles, CaliforniaAges 18 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 - 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 - NCT04049084Enrolling by invitation
Follow-up study for people treated with gene therapy for ADA-SCID
This is a follow-up (no new treatment) study for people who previously received a gene therapy made from their own cells for ADA-SCID. It mainly tracks long-term safety and whether a marker showing the gene change can still be found.
Los Angeles, CaliforniaAges Any age - NCT03835312Recruiting
Transplant plan for children with genetic immune problems and diabetes
This trial tests a two-step transplant approach using immune-related stem cells and islet (pancreas insulin–making) cells in children and teens who have type 1 diabetes caused by a genetic immune problem. It aims to improve insulin control and protect other organs that are being affected by their immune system.
Shanghai, Shanghai MunicipalityAges Up to 18 years - NCT03538899RecruitingPhase 1/Phase 2
Gene therapy for children with an Artemis SCID immune problem
This early-phase study tests an “autologous” gene therapy, meaning they use the child’s own cells, adjusted with a working gene, to help restore immune function. It is for babies and children with Artemis-deficient SCID, aiming to improve T-cell immunity and reduce the need for lifelong infection risk management.
San Francisco, CaliforniaAges 2 months+ - NCT03300830Recruiting
Testing tumors linked to viruses, HIV, and immune disorders
This study collects and analyzes tumor tissue to learn what drives certain cancers and growths linked to viruses, HIV, and immune system problems. Results may help researchers understand disease causes and point to better future treatments.
Bethesda, MarylandAges 18 years+ - NCT03422614Recruiting
Study immune-system disorders in people with primary immune problems
This study looks at what is happening in the immune system for people with an inherited (primary) immune problem. It may help researchers better understand the disease and how it works.
ZurichAges Any age - NCT03478670Enrolling by invitation
Registry follow-up for ADA-SCID patients treated with Strimvelis
This study keeps track of people with ADA-SCID (a rare immune system condition) who previously received Strimvelis or a related treatment. It helps doctors understand long-term outcomes and safety after treatment.
Milan, LombardyAges Any age - NCT03206099Recruiting
Genetic testing study for people linked to other NIH research
This study collects and sequences (reads) your DNA to help researchers understand health and disease. You may be invited because you are connected to another NIH study, and you must agree to testing, sample storage, and sharing de-identified genetic data for future research.
Washington D.C., District of ColumbiaAges 1 day–100 years - NCT02356653RecruitingEarly Phase 1
Stem cell transplant help for children lacking a matching sibling
This expanded-access study offers a specific type of stem cell transplant preparation that removes certain immune cells (CD3 and CD19) from donor stem cells. It is for children who need a transplant but do not have a fully matched sibling donor and whose team cannot use the hospital’s usual matching device protocol.
Philadelphia, PennsylvaniaAges Up to 30 years - NCT01861106RecruitingPhase 2
Bone marrow transplant for GATA2 mutations
This trial tests a bone marrow transplant (called allogeneic hematopoietic stem cell transplant) as a treatment for people with GATA2 mutations or MonoMAC. The goal is to replace faulty immune cells with healthy donor cells, which may reduce infections and improve immune function.
Bethesda, MarylandAges 6–70 - NCT01666080Recruiting
Second bone marrow transplant with gentler chemotherapy
This trial studies a “reduced intensity” second transplant using donated blood-forming cells, for people whose first transplant did not fully and reliably restart blood production. It aims to improve donor blood cell growth while using a less harsh conditioning approach.
Minneapolis, MinnesotaAges Up to 55 years - NCT01890486Recruiting
Collecting information from people having a stem cell transplant
This study aims to collect, store, and share data from patients who are receiving standard intensive treatment and a stem cell transplant from either their own cells or a donor. It may help improve how future patients are treated by building a reliable record of outcomes and care patterns.
Winston-Salem, North CarolinaAges 18–120 - NCT01212055Recruiting
Apheresis for certain immune system gene problems
This trial studies whether an apheresis procedure (removing blood cells through a machine) can help people with specific inherited immune system conditions. Participants will also receive filgrastim to help move certain blood-forming cells for collection.
Bethesda, MarylandAges 18–40 - NCT00001281Recruiting

Common questions
- Are there clinical trials for immunodeficiency?
- Yes. Clin2 currently lists 123 recruiting 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 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 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.
