What this trial studies

This observational study aims to evaluate the control and management of asthma patients in Hong Kong who are receiving step 4 and 5 treatment according to the Global Initiative for Asthma (GINA) guidelines. Over a two-year period, the study will monitor these patients for exacerbations and assess those on biologic therapies for their suitability and outcomes. The goal is to generate local data that can inform healthcare planning for severe asthma and to establish a biologic registry to enhance local physicians' experience with these advanced treatments.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who are on GINA step 4 or 5 asthma treatment.

Not a fit: Patients with other significant respiratory diseases or those who are pregnant may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the management and outcomes for patients with difficult-to-treat and severe asthma.

How similar studies have performed: While there have been studies on asthma management, this specific approach focusing on severe asthma in Hong Kong is novel and aims to fill a local data gap.
