This is a phase III, randomized, multicenter, double-blind, placebo-controlled, parallel-group study to examine the safety and efficacy of AeroVanc in the treatment of persistent MRSA lung infection in patients diagnosed with CF. After the Screening period to confirm study eligibility, participants are randomly assigned in a blinded fashion to receive either AeroVanc 30 mg twice daily (BID), or placebo BID (1:1 active to placebo) by inhalation for 24 weeks or 3 dosing cycles (Period 1). Upon completion of Period 1, participants receive open-label AeroVanc 30 mg BID for an additional 24 weeks or 3 dosing cycles (Period 2), to evaluate long-term safety of AeroVanc. A dosing cycle is defined as 28 days of treatment followed by 28 days of observation.~Participants on a 28-day cyclical on/off anti-Pseudomonal antibiotic regimen enter the Screening period at a time such that the Baseline visit coincide with the end of their anti-Pseudomonas antibiotic cycle. Study drug is thereby administered during the off-cycle, and participants can then resume anti-Pseudomonal therapy during the 28-day observation period. Participants continuing alternating anti-Pseudomonal therapy can continue their treatment during the study drug administration, and observation period.~The primary and secondary analyses are conducted in participants ≤21 years old. Subjects >21 years old are analyzed separately as supportive analyses.
This is a multi-center, randomized phase III study to evaluate the clinical effectiveness of AeroVanc in persistent methicillin-resistant Staphylococcus aureus (MRSA) infection in patients with cystic fibrosis (CF).
