Research Activities

Dr. Cowan is currently a principal investigator for a clinical trial for the feasibility and safety of immunoglobulin treatment in hospitalized COPD patients with frequent exacerbations. The trial is meant to evaluate immunoglobulin treatment in patients with frequent acute exacerbation of COPD, which could be due to antibody deficiency state. In this study, the goal is to determine if this treatment is feasible, safe, tolerable, and potentially effective in reducing the frequency of acute exacerbation of COPD. The concept of antibody deficiency in COPD patients with frequent exacerbations is new. Our group is considered the first group introducing this concept.
