Welcome to the participants area for the OPACE trial.

About OPACE

Azithromycin is a valuable antibiotic. In chronic obstructive pulmonary disease (COPD), it is often used as a prevention treatment rather than to treat active infection. We want to prescribe azithromycin where it has benefit, but avoid unnecessary side effects and reduce the chances of bacteria becoming resistant to it.

Currently, there isn’t much evidence to show what happens when azithromycin is stopped either completely, or just temporarily over the summer in people with COPD. This trial aims to establish the effects of stopping azithromycin prevention in people whose COPD is more stable, who have been taking azithromycin for at least 3 months.

We will compare:

i) Continuing azithromycin, with

li) Stopping azithromycin either completely, or

iii) Stopping over the summer only and continuing azithromycin over the winter.

We will compare effects of these three interventions (trial arms) on your COPD flare-ups, symptoms and quality of life and also find out what factors may affect how individual participants respond.
