Phase II Randomized, Double-Blind, Placebo-Controlled Study of Intravenous Mucoid Exopolysaccharide Pseudomonas Aeruginosa Immune Globulin for Cystic Fibrosis

OBJECTIVES: I. Assess the efficacy of monthly intravenous mucoid exopolysaccharide Pseudomonas aeruginosa immune globulin (MEP IGIV) given over 1 year in reducing the frequency of acute pulmonary exacerbation in patients with cystic fibrosis, mild to moderate pulmonary disease, and mucoid P. aeruginosa colonization. II. Assess the effect of MEP IGIV on FEV1, sputum density of mucoid P. aeruginosa, and the quality of life in these patients. III. Assess the safety of monthly MEP IGIV. IV. Assess population-based MEP IGIV pharmacokinetics during chronic therapy.
