Phase III Randomized Study of the Inhalation of Tobramycin in Patients With Cystic Fibrosis
OBJECTIVES: I. Determine the safety and efficacy of tobramycin in patients with cystic fibrosis who are chronically colonized with Pseudomonas aeruginosa.
II. Determine whether this treatment produces tobramycin-resistant bacteria at a frequency different from the placebo group and whether the emergence of resistance is associated with a lack of clinical response.
|Study Design:||Allocation: Randomized
Primary Purpose: Treatment
|Study Start Date:||June 1995|
|Estimated Study Completion Date:||May 1998|
PROTOCOL OUTLINE: This is a randomized, double blind, placebo controlled, multicenter study.
Patients receive tobramycin or placebo by inhalation twice daily for 28 days followed by 28 days of rest. This treatment is repeated twice, for a total of 3 courses of therapy.
Patients are followed every 2 weeks for the first 8 weeks, then every 4 weeks, and then at 4 weeks after the last treatment.
