Compares treatment options for Asthma
Official title A Study of Efficacy and Safety of Depemokimab Compared With Placebo in Adults and Adolescents With at Risk Type 2 Asthma
ClinicalTrials.gov ID: NCT07456033
What this study is testing
What is Depemokimab?
Depemokimab is an investigational medicine, being studied as a potential treatment for asthma.
Also referred to as GSK3511294.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The aim of this study is to evaluate the efficacy of depemokimab administered as an adjunctive therapy, in participants with Type 2 asthma at risk of exacerbations compared to the guideline recommended standard of care (SoC).
- Phase 3: a large, late-stage study
- You might receive a placebo (an inactive treatment) instead of the study drug.
