Title: The Microbiologic Efficacy and Safety of Two Treatment Regimens of Inhaled Tobramycin Nebuliser Solution (TNS) for the Treatment of Early Onset Pseudomonas Aeruginosa Lower Respiratory Tract Infection in Subjects With Cystic Fibrosis
Brief Summary: This study assessed time to recurrence of infection with Pseudomonas aeruginosa following treatment of the initial infection with tobramycin nebuliser solution. The safety profile of the initial tobramycin treatment was assessed during the first 3 months of the study and patients were followed until the end of the study, month 27.


Options:
A: Inclusion criteria:

* Male or female patients ≥ 6 months old
* Diagnosis of cystic fibrosis (CF) based upon the following historical criteria performed prior to study participation:

  1. confirmed sweat chloride \> 60 mEq/L by quantitative pilocarpine iontophoresis (at least 2 tests), OR
  2. genotype with two identifiable mutations consistent with CF.
* First or early lower respiratory tract infection with Pseudomonas (P.) aeruginosa documented by either of the following:

  1. first infection defined by the first P. aeruginosa isolated from sputum or deep throat cough swab culture, OR
  2. P. aeruginosa from sputum or deep throat cough swab culture following at least 1 year of negative cultures (documented with at least 4 negative cultures during this year and no positive cultures) and no anti-pseudomonal treatment during this 1-year period, OR
  3. P. aeruginosa from sputum or deep throat cough swab culture following at least 2 years of negative cultures (documented with at least 2 negative cultures per year and no positive cultures) and no anti-pseudomonal treatment during this 2-year period.
* Written informed consent by the patient and/or parent/legal guardian according to local country regulations.

Exclusion criteria:

* History of aminoglycoside hypersensitivity or adverse reaction to inhaled aminoglycoside.

* Positive urine pregnancy test at Day 1 (Baseline) for all female patients who have reached menarche.
* Use of macrolide antibiotics as a maintenance therapy for 12 or more days during the 28 days prior to Baseline.
