Phase 3
Completed
Conditions
Bronchiectasis
Interventions
Drug: Placebo
Registration Number
NCT01314716
Lead Sponsor
Gilead Sciences
Brief Summary

The AIR-BX2 study enrolled people with non-cystic fibrosis (non-CF) bronchiectasis and gram-negative airway infection. Participants received two 28-day courses of either Aztreonam for Inhalation Solution (AZLI) or placebo taken 3 times a day. Each course was followed by a 28-day off-drug period. Following the two blinded courses, all participants received a 28-day course of open-label AZLI then were followed for an additional 56 days.

AZLI-AZLIAZLIParticipants were randomized to receive blinded AZLI for 2 cycles of 28 days on treatment with each cycle followed by 28 days off treatment, followed by open-label AZLI for 28 days plus 56 days of treatment-free follow-up.
Placebo-AZLIAZLIParticipants were randomized to receive blinded placebo to match AZLI for 2 cycles of 28 days on treatment with each cycle followed by 28 days off treatment, followed by open-label AZLI for 28 days plus 56 days of treatment-free follow-up.

Primary Outcome Measures
NameTimeMethod
Change in QOL-B Respiratory Symptoms Score at Day 28Baseline to Day 28

The mean (SD) change in the Respiratory Symptoms score on the Quality of Life Questionnaire-Bronchiectasis (QOL-B) was measured from baseline to the end of Course 1 (Day 28). The QOL-B respiratory symptoms score was transformed onto a scale of 0-100, with higher scores representing a better quality of life.

Secondary Outcome Measures
NameTimeMethod
Change in QOL-B Respiratory Symptoms Score at Day 84Baseline to Day 84

The mean (SD) change in the Respiratory Symptoms score on the QOL-B was measured from baseline to the end of Course 2 (Day 84). The QOL-B respiratory symptoms score was transformed onto a scale of 0-100, with higher scores representing a better quality of life.

Time to Protocol-Defined Exacerbation (PDE)Baseline to Day 112

Protocol-defined exacerbation was defined as an acute worsening of respiratory disease that triggered the initiation of a non-study antibiotic meeting at least 3 major criteria, or 2 major and at least 2 minor criteria.

* Major Criteria: increased sputum production; increased discoloration of sputum; increased dyspnea; increased cough

* Minor Criteria: fever (\> 38º C) measured during clinic visit; increased malaise or fatigue; forced expiratory volume in 1 second (FEV1) (L) or forced vital capacity (FVC) decreased \> 10% from baseline; new or increased hemoptysis
