Phase II Randomized, Double-Blind, Placebo-Controlled Study of Intravenous Mucoid Exopolysaccharide Pseudomonas Aeruginosa Immune Globulin for Cystic Fibrosis
Not Provided

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.

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.

  • Mucoid Pseudomonas aeruginosa colonization documented in at least 2 serial expectorated sputum cultures in the year prior to entry Screening specimen meets requirement for 1 culture
  • Documented exacerbation of respiratory tract infection At least 1 hospitalization and/or course of parenteral or nebulized antibiotic therapy in each of the 2 years prior to entry
  • At least 2 serial spirometry tests over at least 6 months prior to entry FEV1 range no more than 15% relative to maximum value
  • None of the following within 6 months prior to entry: Pseudomonas (Burholderia) cepacia or atypical mycobacteria in respiratory tract Pulmonary hemorrhage with greater than 5% drop in hematocrit Pneumothorax requiring chest tube
  • No life-threatening CF sequelae, e.g.: Severe cirrhosis with ascites or bleeding Severe distal intestinal obstruction syndrome requiring cessation of oral intake Poorly controlled insulin-dependent diabetes with acetonuria

Prior/Concurrent Therapy
