Title: A Phase 3, Double-Blind, Multicenter, Randomized, Placebo-Controlled Trial With Aztreonam Lysinate for Inhalation in Cystic Fibrosis Patients With Pulmonary P. Aeruginosa Requiring Frequent Antibiotics (AIR-CF2)
Brief Summary: The purpose of this study was to evaluate the safety and efficacy of aztreonam for inhalation solution (AZLI) in patients with cystic fibrosis (CF) and lung infection due to Pseudomonas aeruginosa (PA).


Options:
A: Inclusion Criteria:

* CF as diagnosed by:

  2. Two well-characterized genetic mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene; or
  3. Abnormal nasal potential difference with accompanying symptoms characteristic of CF.

* Participants must have received three or more courses of TIS within the previous 12 months.
* Participants on chronic azithromycin must have had no change in regimen in the previous 3 months and must have had a need for TIS and/or additional antipseudomonal therapy since initiation of azithromycin.
* Forced expiratory volume in 1 second (FEV1) between (and including) 25% and 75% predicted at Screening.
* Ability to perform reproducible pulmonary function tests.
* Arterial oxygen saturation (SaO2) greater than or equal to 90% on room air at Screening.

Exclusion Criteria:

* Current use of oral corticosteroids in doses exceeding the equivalent of 10 mg prednisone a day or 20 mg prednisone every other day.
* History of sputum or throat culture swab yielding Burkholderia cepacia in the past 2 years.

* Any serious or active medical or psychiatric illness, which in the opinion of the investigator would have interfered with participant treatment, assessment, or compliance with the protocol.

* Fasting glucose levels \<126.
* Weight stable within 5% in previous 3 months.
* Free from illness for two months.
* Male and female 16 and older, who are done growing
* Willing to come in for visits every 3 months.
* Patients receiving infrequent short bursts of systemic glucocorticoids may be considered for the study inclusion if: a. they have not received systemic glucocorticoids steroids for at least one month, b. they did not receive the steroids for more than 14 consecutive days or 28 days total in six months
