CF patients often have lung infections that occur repeatedly or worsen over time. The lung infections are often caused by a bacteria called Pseudomonas aeruginosa (PA). Treatment with antibiotics can stop or slow down the growth of the bacteria. The antibiotics may be given by mouth, intravenously (IV), or by inhalation as a mist. The purpose of this study was to evaluate the safety and efficacy of AZLI, an investigational formulation of the antibiotic aztreonam and administered TID using the PARI eFlow® electronic nebulizer, in CF patients with PA.
In this study, participant eligibility was assessed at a screening visit 7 to 14 days prior to the baseline visit (Day 0). Those participants who continued to meet eligibility criteria at Day 0 were randomized and began a 28-day course of blinded study treatment (AZLI TID or placebo TID). Participants returned for clinic visits at Day 14, an end of treatment visit at Day 28, and a follow-up visit 14 days after the last dose of study drug (Day 42).

- Change in CFQ-R Respiratory Symptoms Scale (RSS) Score [ Time Frame: Day 0 to Day 28 ]The CFQ-R was administered at baseline and every visit thereafter. The endpoint was change in respiratory symptoms from baseline, assessed with the CFQ-R respiratory symptoms scale (RSS; range of scores: 0-100; higher scores indicate fewer symptoms).
- Change in CFQ-R RSS Score [ Time Frame: Day 0 to Day 14 ]The CFQ-R was administered at baseline and every visit thereafter. The endpoint was change in respiratory symptoms from baseline, assessed with the CFQ-R RSS (range of scores: 0-100; higher scores indicate fewer symptoms).
- Change in CFQ-R RSS Score [ Time Frame: Day 0 to Day 42 ]The CFQ-R was administered at baseline and every visit thereafter. The endpoint was change in respiratory symptoms from baseline, assessed with the CFQ-R RSS (range of scores: 0-100; higher scores indicate fewer symptoms).
- Percent Change in FEV1 (L) [ Time Frame: Day 0 to Day 28 ]Spirometry was performed according to American Thoracic Society (ATS) guidelines at each visit. The percent change from baseline in forced expiratory volume (liters) in one second (FEV1) was determined at Day 28.
- Change From Baseline in Pseudomonas Aeruginosa (PA) Log10 Colony Forming Units (CFU) Per Gram of Sputum [ Time Frame: Day 0 to Day 28 ]Sputum samples were collected at all participant visits of the study for analysis of microbiology endpoints. Sputum samples were processed for qualitative and quantitative culture of PA (each morphotype). Due to the skewness of the distribution of CFU data, the data were transformed using the base 10 logarithm, in an attempt to normalize the data and allow for parametric tests, before calculating changes. To account for zero values, 1 was added to each CFU measurement before being transformed. Any CFU data values where PA was not isolated from a valid culture were set to zero.
- Number of Participants Receiving Intravenous (IV) or Inhaled Antipseudomonal Antibiotics Other Than Trial Drug [ Time Frame: Day 0 to Day 42 ]Use of IV and inhaled antipseudomonal antibiotics was compiled from data recorded on the Concomitant Medications eCRF.
- Number of Participants Hospitalized at Least Once Between Day 0 and Day 42 [ Time Frame: Day 0 to Day 42 ]Details of all hospitalizations, including the dates of admission and discharge, were recorded on the SAE eCRF.
