Azithromycin for Acute Exacerbations Requiring Hospitalization (BACE)
Belgian Trial With Azithromycin During Acute COPD Exacerbations
This project (funded by the IWT-TBM program) will organize a randomized placebo-controlled multicenter intervention trial in 500 COPD patients to study the effectiveness and safety of azithromycin therapy in the acute setting of COPD exacerbations requiring hospital admission. Although long-term use of azithromycin is proven effective to prevent exacerbations, inherent risks outweigh the benefits. By reducing the dose and duration of the azithromycin treatment and by restricting the treatment to acute periods with highest risk for treatment failure, benefits may counterbalance potential side effects, which may result in a new treatment strategy for these acute events.
The present study is designed by the services of respiratory medicine of the Leuven and Ghent University hospitals but will run in total in 17 different large hospitals in Belgium, of which 12 are located in Flanders.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Time to clinical failure
Time Frame: Will be assessed between day 1 (from 1 hour after first drug intake) till day 90 (24 hours after last study drug intake)
|
Clinical failure is a composite endpoint as multiple clinical interventions may indicate that an initiated therapy is failing. Clinical failure is defined as the composite of death, treatment intensification (additional dose of systemic steroids, switch antibiotics for respiratory reasons or new course of systemic steroids and/or antibiotics) and step up in hospital care for respiratory reasons (from ward to ICU during index event, or from home to ward or ICU (new admission) after discharge). Primary outcome measure will also be analysed in following subgroups as an exploratory analysis:
|
Will be assessed between day 1 (from 1 hour after first drug intake) till day 90 (24 hours after last study drug intake)
