Blood cell collection study for immune system disorders
Treatments studied
Part of Blood & lymphatic, Immune system & allergy clinical trials.
This study collects blood-forming cells from people with low CD4 counts and healthy volunteers to learn how the immune system works. It may help researchers better understand and treat conditions like idiopathic CD4 lymphocytopenia.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 65 years old.
- You weigh at least 110 pounds but less than 368 pounds, and your body weight is under 175% of the ideal for your height.
- You have a diagnosis of idiopathic CD4 lymphocytopenia (low CD4 cells) or a similar immune problem, or you are a healthy volunteer.
- Your blood counts (like hemoglobin) meet minimum levels as determined by tests.
- You are willing to have blood samples stored for future research and to undergo genetic testing.
- You can commit to follow-up visits and agree to use birth control during the study if you are able to have children.

This study looks for what causes and how idiopathic low CD4 cells happen over time, using blood and tissue samples. It may help doctors learn why this occurs and how to better track people with it.
This study collects blood cells and bone marrow from people with immune system or blood disorders, and from healthy volunteers. Researchers will study these cells and may convert them into special stem cells (iPS cells) to better understand diseases and develop treatments.
This Phase 1/2 study tests a long-acting IL-7 medicine to raise low CD4 immune cells in people with idiopathic CD4 lymphopenia. Because this is a dose-escalation study, the goal is to check safety and see if the treatment affects immune cell levels.
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.
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.
This trial tests a new gene therapy that uses a person's own blood stem cells and T cells, which are corrected with a gene-editing tool called base editing. It is designed for people with a specific CD40L gene mutation who also have liver problems and portal hypertension. The goal is to see if this treatment can improve their immune system and liver health.
