conductance regulator (CFTR) gene AND One or more clinical features consistent with CF.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary objective of this study is to evaluate the proportion of patients with PA-negative cultures at all time points during a 6-month monitoring period (through Day 196) after cessation of active treatment; microbiological cultures will be obtained at Baseline, Day 28 (end of treatment), Day 56 (1 month after
completing AZLI), Day 112 (3 months after completing AZLI), and Day 196 (6 months after completing AZLI). PA-specific antibody titers will be obtained at Baseline, Day 28, and Day 196. Safety endpoints will include adverse events, airway reactivity (study drug-induced bronchspasm), vital signs, blood biochemistry
and hematology. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Microbiological cultures will be obtained at Baseline (Day 1), Day 28 (end of treatment), Day 56 (1 month after completing AZLI), Day 112 (3 months after completing AZLI), and Day 196 (6 months after completing AZLI). PA-specific antibody titers will be obtained at Baseline, Day 28, and Day 196. Airway reactivity (study drug-induced bronchospasm) will be assessed at Baseline and Day 28. Blood biochemistry and hematology will be assessed at Screening, Baseline, Day 28 and Day 196. Adverse events and vital signs will be assessed at Screening, Baseline, Day 28, Day 56, Day 112 and Day 196. |
|
E.5.2 | Secondary end point(s) |
In patients ≥ 6 years of age:
• Change from baseline in FEV1 % predicted at Days 28, 56, 112, and 196;
• Change from baseline in CFQ-R Respiratory Symptoms Score (RSS) at Days 28, 56, 112, and 196.
In all patients:
• Proportion of patients with PA-negative cultures at Days 28, 56, 112 and 196;
• Use of additional (non-study) antipseudomonal antibiotics (as a marker for PA exacerbation);
• Change from baseline in weight, height, and body mass index (BMI) at Days 28, 56, 112, and 196;
In patients < 6 years of age:
• Pharmacokinetics: 1 peak plasma sample will be obtained 1 hour after the first dose of AZLI (Day 1); 1 trough plasma sample will be obtained immediately prior to the last dose of AZLI (Day 28 + 4 days). Plasma aztreonam concentrations at each time point will be summarized (mean, median, standard deviation [SD], minimum, maximum, and number of samples). |
