  Purpose

The AIR-BX-2 study is for people who have been diagnosed with non-CF bronchiectasis and have gram-negative airway infection. This is a randomized study, the participants will be selected by chance (like flipping a coin) to receive one of two treatments (AZLI or Placebo). This is a double-blind study which means participants and their study doctors will not know what treatment they are assigned to receive. Participants will receive two 28 day courses of either AZLI or placebo taken 3 times a day. Each course has a 28 day off-drug period. Following the blinded courses, all participants will receive AZLI for the third 28 day course.

Based on observed safety and effectiveness of AZLI in the adult CF population, and due to the similarities in the lung disease for patients with CF and non-CF bronchiectasis, AZLI represents a potential treatment for people with non-CF bronchiectasis and infection of the airways.

Primary Outcome Measures:
  • Change in QOL-B Respiratory Symptoms Score [ Time Frame: Baseline to end of treatment course 1 (Day 28) ] [ Designated as safety issue: No ]
    Change in the Respiratory Symptoms score on the Quality of Life Questionaire-Bronchiectasis(QOL-B) from baseline to the end of the placebo-controlled course 1 treatment with AZLI or placebo (Day 28)


Secondary Outcome Measures:
  • Change in QOL-B Respiratory Symptoms and Physical Functioning Scores [ Time Frame: Baseline to end of treatment course 1 and 2. ] [ Designated as safety issue: No ]
  • Time to Exacerbation [ Time Frame: From baseline to open label treatment (4 months) ] [ Designated as safety issue: No ]
    Time to protocol defined exacerbation prior to open-label AZLI treatment.

Arms Assigned Interventions
Experimental: AZLI Drug: Aztreonam for Inhalation Solution (AZLI)
75 mg Aztreonam lysine monohydrate administered via nebulizer, three times a day for a 28 day period.
Placebo Comparator: Sugar and Saline Solution Drug: Placebo
