          -  Abnormal nasal transepithelial potential difference test OR

          -  Two well-characterized, disease-causing genetic mutations in the CF transmembrane
             conductance regulator (CFTR) gene AND

          -  One or more clinical features consistent with CF

          -  Documented new onset of positive lower respiratory tract culture (e.g., throat swab,
             sputum, or BAL) for PA within 30 days of study entry (prior to screening visit)
             defined as either first lifetime documented PA-positive culture OR PA recovered after
             at least a 2 year history of PA-negative respiratory cultures (at least 2 cultures per
             year)

          -  Forced expiratory volume in 1 second (FEV1) ≥ 80% predicted at screening visit
             (subjects ≥ 6 years of age)

          -  Clinically stable with no evidence of significant respiratory symptoms or, if obtained
             for clinical evaluation, no chest radiograph findings at screening that would have
             required administration of IV antipseudomonal antibiotics, oxygen supplementation, or
             hospitalization.

          -  All sexually active females who were of childbearing potential must agree to use a
             highly effective method of contraception during heterosexual intercourse throughout

             have used the same method for at least 3 months prior to study drug dosing.

          -  Males must agree to use barrier contraception (condom with spermicide) during
             heterosexual intercourse from screening through to study completion and for 90 days
             from the last dose of study investigational medicinal product

          -  Participants and/or parent/guardian must be able to give written informed consent
             prior to any study related procedure

        Exclusion Criteria:

          -  Use of IV or inhaled antipseudomonal antibiotics within 2 years of study entry
             (screening visit)

          -  Use of oral antipseudomonal antibiotics within 30 days of study entry (screening
             visit)

          -  History of sputum or throat swab culture yielding Burkholderia spp. within 2 years
             prior to screening visit

          -  History of local or systemic hypersensitivity to monobactam antibiotics

          -  History of intolerance to inhaled short acting beta 2 agonists

          -  History of lung transplantation

          -  History of AZLI (or Cayston®) administration

          -  Administration of any investigational drug or device within 28 days prior to screening
             visit or within 6 half-lives of the investigational drug (whichever is longer)

          -  Current use of oral corticosteroids in doses exceeding the equivalent of 10 mg
             prednisone per day or 20 mg prednisone every other day

          -  Current requirement for daily continuous oxygen supplementation or requirement of more
             than 2 L/minute at night

          -  Hospitalization for pulmonary-related illness within 28 days prior to screening visit

          -  Changes in or initiation of chronic azithromycin treatment within 28 days prior to
             screening visit

          -  Changes in antimicrobial, bronchodilator (BD), corticosteroid, dornase alfa, or
             hypertonic saline medications within 7 days prior to screening visit; for participants
             on a stable regimen of hypertonic saline (28 days on/28 days off), beginning or ending
             a cycle of hypertonic saline is allowed

          -  Changes in physiotherapy technique or schedule within 7 days prior to screening visit

             months, defined as:

          -  Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) > 5 times upper
             limit of normal (ULN), or

          -  Serum creatinine > 2 times ULN for age

          -  Pregnant or lactating females; a negative urine pregnancy test is required for all
             females of childbearing potential (unless surgically sterile), and confirmatory serum
