Safety and Effectiveness of AZLI (an Inhaled Antibiotic) in Adults With Non-Cystic Fibrosis Bronchiectasis

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.

Placebo

Drug

Placebo to match AZLI administered via nebulizer three times daily

Primary outcomes

  1. Change in QOL-B Respiratory Symptoms Score at Day 28

    Time frame: Baseline 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 outcomes

  1. Change in QOL-B Respiratory Symptoms Score at Day 84

    Time frame: Baseline 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.

  2. Time to Protocol-Defined Exacerbation (PDE)

    Time frame: 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
