Trial acronym
Linked study record
This is a follow-up study of a study in children and adults evaluating the effect of erdosteine on respiratory exacerbation rate of children and adults with bronchiectasis taken twice daily for a 12 month period - a multicentre double-blind, randomised controlled trial.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Erdosteine 300mg capsules: Oral twice daily doses for 2 weeks [one capsule (300mg) per dose for children >20kg; half capsule (150mg) per dose for children 15-20kg]

Adherence will be monitored by return of bottles or capsule packaging.

In a subset of participants, we will also evaluate if inflammatory and/or microbial biomarkers will identify pathways and/or predict those at greater risk of recurrent respiratory exacerbations. These outcomes will not be reported in the trial. Participants for this component will be based on whether they consent to these additional procedures (sputum and blood). Where possible, bloods and sputum will be taken at baseline and at commencement of an exacerbation.
