Lung infections are a chronic problem for patients with cystic fibrosis (CF). Some patients with CF may have a type of bacteria called Pseudomonas aeruginosa in their lungs that can cause infections or make their symptoms worse. Tobramycin inhalation solution (TOBI) is an approved antibiotic, which is inhaled directly into the lungs, and can be used to manage these infections. Tobramycin inhalation powder (TIP) is a new, experimental powder formulation of tobramycin that is inhaled directly into the lungs using a T-326 inhaler. The purpose of this research study is to determine if TIP is safe and effective when compared to placebo (a powder with no medicine) treatment.

Further study details as provided by Novartis:

Primary Outcome Measures:
  • Forced expiratory volume in 1 second (FEV1) measured at week 1 and week 5.

Secondary Outcome Measures:
  • Time until first antipseudomonal antibiotic (an antibiotic used to treat bacteria of a certain type [the genus pseudomonas]) is used
  • Relative changes in FEV1 % predicted for patients who received TIP starting at visit 1 and for patients who received placebo starting at week 9, compared to all subsequent visits.
  • Relative change in FEV1 % predicted for patients who received placebo from week 5 to week 13
  • Relative change in FEV1 % predicted for patients who received placebo (from the average of four assessments [weeks 1, 2, 5, and 9] to week 13)
  • Change from baseline in susceptibility of pseudomonas to the antibiotic during the study measured at weeks 5, 9, 13, 17, 21, and 25, and change from baseline in quantity of pseudomonas found in sputum during the study measured at weeks 5, 9, 13, 17, 21,
