Phase III Randomized Study of the Inhalation of Tobramycin in Patients With Cystic Fibrosis

March 24, 2015 updated by: FDA Office of Orphan Products Development

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.
