Clinical Trial Summary

The overall goal of the study is to investigate the functional, biochemical, and gene expression effects of Interferon-gamma 1-b (IFN-γ) on the neutrophils of patients with Chronic Granulomatous Disease (CGD). The investigators hypothesize that the clinical effects demonstrated in patients with CGD treated with IFN-γ (decreased number and severity of infections) are the result of biochemical processes and upregulation of specific genes, which lead to enhanced functionality of this immune cell population.
