Safety and Efficacy Study of Aztreonam for Inhalation Solution (AZLI) in Cystic Fibrosis Patients With P. Aeruginosa — AIR-CF2  

Cystic Fibrosis Clinical Trial

Official 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)

Clinical Trial 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).

Clinical Trial Description

Patients with CF often have lung infections that occur repeatedly or worsen over time. The lung infections are often caused by a bacteria called 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 aztreonam for inhalation solution (AZLI), an investigational formulation of the antibiotic administered using the eFlow® Electronic Nebulizer by PARI GmbH, in CF patients with PA.

In this study, participants were screened for eligibility at Visit 1 (Day -42) and returned to the center for Visit 2 after a 14-day evaluation period. At Visit 2 (Day -28), participants began a 28-day course of open-label Tobramycin Inhalation Solution (TIS). At Visit 3 (Day 0), following completion of the 28-day course of TIS, participants began randomized, blinded treatment with either AZLI twice a day (BID) or three times a day (TID) or placebo BID or TID, and continued treatment for a total of 28 days, with a clinic visit at Day 14 (Visit 4) and at the end of treatment (Visit 5 [Day 28]). Participants returned for visits every 2 weeks for 8 weeks after the end of the blinded treatment (Visits 6 to 9 [Days 42 to 84]).

Two hundred and forty-seven participants were treated in the TIS phase of this study. Two hundred and eleven subjects completed the TIS phase and were treated in the placebo-controlled phase with study drug (AZLI or placebo). ;
