Is this trial a fit for you?

What this trial studies

This open-label, single-arm, multicenter observational study collects primary data on Breztri in routine clinical practice in Korea. It aims to characterize safety outcomes and assess real-world effectiveness over up to 24 weeks, enrolling at least 600 patients who start Breztri per approved labeling. Participation is based on physician practice patterns and informed consent, with around 30 study sites. Data will reflect how Breztri performs outside controlled trials, including any previously unrecognized adverse reactions. Concomitant medications may be used as clinically indicated, and follow-up schedules are determined by treating physicians.

Why it matters

Potential benefit: If successful, the study could provide real-world evidence of Breztri’s safety and effectiveness in Korean patients with COPD or asthma.

How similar studies have gone: Post-marketing surveillance in real-world settings has shown value in identifying safety signals and practical effectiveness in similar inhaled therapies.
