Official title
Study of Immune Responses and Safety of Recombinant CD40 Ligand in Patients With X-Linked Hyper IgM Syndrome
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The primary goal of this Phase I/II study is to assess the immune response and safety of recombinant human CD40 ligand (rhuCD40L) in patients with X-linked hyper IgM syndrome (XHIM). XHIM is a rare genetic disease caused by mutations in the gene encoding CD40 ligand. Individuals with this syndrome fail to make gamma immune globulin, frequently suffer from opportunistic infections, and are at an increased risk of developing cancer. Despite treatment with gamma globulin replacement therapy, the expected survival of patients with XHIM is less than 20 percent by the age of 25. In a mouse model of this syndrome, treatment with man-made CD40 ligand protein protected the mouse from opportunistic infections, restored the mouse's ability to make gamma globulin, and improved survival. We want to determine if a similar approach can work in humans with XHIM. The study will be conducted at the Clinical Center of the National Institutes of Health in Bethesda, Maryland. For most patients, rhuCD40L will be administered by injection under the skin over a period of six months and follow-up exams are required at 2-month intervals for an additional 6 months. During the study, patients will be maintained on intravenous gamma globulin, antibiotics to protect against opportunistic infection, and, if needed, growth factors to control neutropenia. The immune response to rhuCD40Lwill be measured by routine methods such as measuring a patient's ability to synthesize gamma globulin when challenged with immunizations to keyhole limpet hemocyanin (KLH) and Bacteriophage Phi-X 174 (Phi-X 174). Our long-term goal is to define a therapeutic regimen that will provide effective immunological reconstitution to patients with XHIM and improve their life expectancy.
