Condition: Idiopathic CD4 Lymphopenia · Sponsor: National Institute of Allergy and Infectious Diseases (NIAID)
Background: Idiopathic CD4 lymphopenia (ICL) is a syndrome characterized by low levels of certain immune cells called CD4 T cells. The low CD4 T cells renders people with ICL prone to many types of severe infections, autoimmune diseases, and cancers. Although these infections and diseases can be treated whenever occur, there is currently no treatment that targeting the underlying deficiency of CD4 T cells can provide a definitive treatment for people with ICL. Objective: To test a new drug (NT-17) in people with ICL which can increase the number of CD4 T cells Eligibility: People aged 18 to 75 years with ICL who are also enrolled in NIH protocol 09-I-0102. Design: Participants will be screened. They will have a physical exam and blood tests. Some participants with high suspicion of central nervous system infection or history of such infections may also undergo a lumbar puncture. A thin needle will be inserted into their lower back to draw out a sample of the fluid around their spinal cord. Participants will receive 3 doses of NT-17, each about 12 weeks apart. NT-17 is injected into the muscle of the upper arm, thigh, or buttock. They will visit the clinic 5 days before each dose and again 2 and 4 weeks after each dose. Blood will be drawn at all visits. Participants will undergo leukapheresis 3 times. Blood will be drawn from a needle in one arm. The blood will pass through a machine that separates out the white blood cells. The remaining blood will be given back thr…
