Brief Summary:

This is an open-label, multi-center study in pediatric patients age 3 months to less than 18 years with cystic fibrosis (CF) and newly detected Pseudomonas aeruginosa (PA) pulmonary colonization/infection. All eligible participants will be treated with a 28-day course of Aztreonam for Inhalation Solution (AZLI) 75 mg 3 times daily. After completion of study drug, subjects will be followed up through Day 196 for safety and recurrence of PA.

The primary objective is to evaluate the proportion of participants with PA-negative cultures at all time points during a 6-month monitoring period (through Day 196) after cessation of AZLI treatment. Microbiological cultures will be obtained at Baseline, Day 28 (end of AZLI treatment), Day 56 (1 month after completing AZLI treatment), Day 112 (3 months after completing AZLI treatment), and Day 196 (6 months after completing AZLI treatment).

Outcome Measures

Primary Outcome Measures :
  1. Percentage of Participants With PA-negative Cultures at All Time Points After Cessation of Active Treatment (Evaluable Analysis Set) [ Time Frame: Day 28 to Day 196 ]
    The percentage of participants with PA-negative cultures at all time points after cessation of active treatment at Day 28 (assessed at Days 56, 112, and 196) was summarized for the Evaluable Analysis Set.

  2. Percentage of Participants With PA-negative Cultures at All Time Points After Cessation of Active Treatment (Sensitivity Analysis Set) [ Time Frame: Day 28 to Day 196 ]
    The percentage of participants with PA-negative cultures at all time points after cessation of active treatment at Day 28 (assessed at Days 56, 112, and 196) was summarized for the Sensitivity Analysis Set.


Secondary Outcome Measures :
  1. Change From Baseline in FEV1% Predicted [ Time Frame: Baseline to Days 28, 56, 112, and 196 ]
    Spirometry assessments were performed only in participants ≥ 6 years of age. Forced expiratory volume in 1 second (FEV1) % predicted was defined as FEV1 of the participant divided by the average FEV1 in the population for any person of similar age, sex and body composition.

  2. Change From Baseline in CFQ-R RSS Score [ Time Frame: Baseline to Days 28, 56, 112, and 196 ]
    Respiratory symptoms (eg, coughing, congestion, wheezing) were assessed with the Cystic Fibrosis Questionnaire - Revised (CFQ-R) Respiratory Symptoms Scale (RSS) only in participants ≥ 6 years of age. The range of scores (units) is 0 to 100 with higher scores indicating fewer symptoms.

  3. Percentage of Participants With PA-negative Cultures [ Time Frame: Days 28, 56, 112, and 196 ]
    The percentage of participants with a PA-negative culture was summarized at each visit.

  4. Use of Additional (Non-study) Antipseudomonal Antibiotics [ Time Frame: Baseline to Day 196 ]
    The percentage of participants who used additional (non-study) antipseudomonal antibiotics (an indication of PA exacerbation) while on treatment and posttreatment was summarized.

  5. Change From Baseline in Weight [ Time Frame: Baseline to Days 28, 56, 112, and 196 ]
  6. Change From Baseline in Height [ Time Frame: Baseline to Days 28, 56, 112, and 196 ]
  7. Change From Baseline in Body Mass Index (BMI) [ Time Frame: Baseline to Days 28, 56, 112, and 196 ]
  8. Pharmacokinetics (PK) Peak and Trough Plasma Concentrations of Aztreonam [ Time Frame: Day 1 (1 hour postdose) and Day 28 (immediately prior to dosing) ]
    The plasma concentration of aztreonam for participants < 6 years of age was obtained 1 hour after the first dose of AZLI on Day 1 and immediately prior to the last dose of AZLI on Day 28.

Criteria

Inclusion Criteria:

  • Males or females age 3 months to less than 18 years

  • Documented sweat chloride ≥ 60 mEq/L by quantitative pilocarpine iontophoresis test OR
  • 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)

  • Changes in physiotherapy technique or schedule within 7 days prior to screening visit
  • Abnormal renal or hepatic function results at most recent test within the previous 12 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 pregnancy test in the event of an initial positive urine test result
  • Any serious or active medical or psychiatric illness (including drug or alcohol abuse), which in the opinion of the investigator, would interfere with treatment, assessment, or compliance with the protocol
  • Presence of a condition or abnormality that would compromise the patient's safety or the quality of study data, in the opinion of the investigator
