Brief Summary:

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.

Condition or disease Intervention/treatment Phase
Cystic Fibrosis Bacterial Infections Drug: mucoid exopolysaccharide P. aeruginosa immune globulin IV Phase 2

Detailed Description:

PROTOCOL OUTLINE: This is a randomized, double-blind study. Patients are stratified by participating institution.

Patients are randomly assigned to 1 of 3 groups: low-dose intravenous mucoid exopolysaccharide Pseudomonas aeruginosa immune globulin (MEP IVIG), high-dose MEP IVIG, or placebo. Therapy is administered every 28 days for 12 months. Treatment is not initiated in the presence of an acute asthmatic attack.

Concurrent chronic suppressive antibiotics are permitted.

Study Type : Interventional  (Clinical Trial)
Enrollment : 170 participants
Allocation: Randomized
Masking: Double
Primary Purpose: Treatment
Study Start Date : July 1995
