Episode notes
Tezepelumab's Upstream Mechanism
- Tezepelumab targets TSLP, an upstream mediator affecting both T2 and non-T2 inflammatory asthma pathways.
- This may benefit patients with non-allergic or non-eosinophilic asthma phenotypes not helped by current biologics.
Key Trial Outcomes Defined
- The primary outcome was annualized asthma exacerbation rate, providing a meaningful clinical endpoint.
- Secondary outcomes included changes in lung function, symptoms, and quality of life with predefined clinical significance.
Thorough Subgroup & Statistical Design
- Subgroup analyses by eosinophil count, exhaled nitric oxide, and allergen sensitivity were used to assess tezepelumab's broad efficacy.
- Hierarchical testing minimized type 1 error due to multiple statistical comparisons.
