Brief summary

The general aim of this project is to conduct a randomized, double-blind, placebo, placebo-controlled clinical trial of azithromycin to determine whether treatment from infancy is safe and will prevent the onset of bronchiectasis. One hundred and thirty infants will be recruited from CF clinics in Australia and New Zealand and treated from 3 months to three years of age. The primary outcome will be the proportion with radiologically-defined bronchiectasis at 3 years of age. Safety and mechanistic evaluations will also be undertaken.
