Outcomes

Primary Outcome Measures

Rate of Protocol-defined Exacerbations (PDE) From Baseline Through Week 24
PDEs were characterized by a change or worsening from baseline of 1 or more documented signs or symptoms (decreased exercise tolerance, increased cough, increased sputum or chest congestion, decreased appetite, or other signs or symptoms) associated with the use of non-study IV or inhaled antibiotics and be verified by a blinded independent adjudication committee.

Secondary Outcome Measures

Average Actual Change From Baseline in FEV1 % Predicted Across All Courses of AZLI/Placebo Treatment (Weeks 4, 12 and 20)
FEV1 % predicted is defined as FEV1 of the patient divided by the average FEV1 in the population for any person of similar age, sex and body composition. The adjusted mean is from a mixed-effect model repeated measures (MMRM) analysis. The model includes terms for baseline value, previous exacerbations (1, 2, ≥ 3), treatment, visit (categorical), and treatment by visit interaction.
Percentage of Participants Who Used Non-study IV or Inhaled Antibiotics for PDEs
Time to First Protocol-defined Pulmonary Exacerbation
The time to first protocol-defined pulmonary exacerbation was calculated using the Kaplan-Meier method.
Rate of Hospitalizations for a Respiratory Event
The rate of hospitalizations for a respiratory event per participant year was calculated using negative binomial regression analysis.
Average Change From Baseline in the CFQ-R Respiratory Symptom Scale (RSS) Score Across All Courses of AZLI/Placebo Treatment (Weeks 4, 12 and 20)
Respiratory symptoms (eg, coughing, congestion, wheezing) were assessed with the Cystic Fibrosis Questionnaire - Revised (CFQ-R) Respiratory Symptoms Scale (RSS). The range of scores (units) was 0 to 100 with higher scores indicating fewer symptoms. The adjusted mean is from a mixed-effect model repeated measures (MMRM) analysis. The model includes terms for baseline value, previous exacerbations (1, 2, ≥ 3), treatment, visit (categorical), and treatment by visit interaction.

5. Study Description

Brief Summary
The primary objective of this study is to evaluate the safety and efficacy of a CAT regimen with aztreonam for inhalation solution (AZLI) and tobramycin inhalation solution (TIS) in adult and pediatric subjects with cystic fibrosis (CF) and pulmonary Pseudomonas aeruginosa (PA) infection. Participants will be enrolled in a 28 day TIS run-in phase, and will be eligible for randomization in the comparative phase if they have not received non-study oral antibiotics for a respiratory event, or IV or inhaled antibiotics for any indication between Visits 2 and 3, have not developed a condition requiring hospitalization or other change in clinical status which, in the opinion of the investigator would preclude their ability to continue in the study, and have demonstrated at least 50% TIS compliance. Participants enrolled in the comparative phase will be randomized to receive 3 cycles of treatment, each cycle consisting alternating regimens: AZLI or placebo for 28 days followed by TIS for 28 days.
