A 52-week, Randomised, Double-blind, Double-dummy, Parallel Group, Multi-centre, Non-inferiority Study Assessing Exacerbation Rate, Additional Measures of Asthma Control and Safety in Adult and Adolescent Severe Asthmatic Participants With an Eosinophilic Phenotype Treated With GSK3511294 Compared With Mepolizumab or Benralizumab

GlaxoSmithKline·interventional·Posted Jan 22, 2021·Updated May 18, 2026

In Brief

A Phase 3 clinical trial evaluating GSK3511294 (Depemokimab), Mepolizumab, and 4 other interventions for Asthma. Completed, enrolled 1,717 participants across 397 sites in 21 countries.

Detailed Summary

This study will assess whether switching participants who have benefitted from mepolizumab or benralizumab to GSK3511294 (Depemokimab) is non-inferior to maintaining current treatment on the annualized rate of clinically significant exacerbations in participants with severe asthma with an eosinophilic phenotype. Throughout the study, all participants will continue their non-biologic Baseline standard of care (SoC) asthma treatment.
