What competitors treat the same condition as GSK’s mepolizumab?
Mepolizumab (GSK) targets IL‑5 and is used for severe eosinophilic asthma. The main competitors are other biologics that treat eosinophilic asthma by blocking IL‑5, the IL‑5 receptor, or related pathways:
- Benralizumab (AstraZeneca): anti–IL‑5 receptor alpha (targets the receptor on eosinophils).
- Reslizumab (formerly Teva): anti–IL‑5 (another approach to the IL‑5 pathway).
- Dupilumab (Sanofi/Regeneron): anti‑IL‑4Rα (targets IL‑4/IL‑13 signaling, used for type 2 inflammation including some severe asthma patients).
- Omalizumab (Novartis): anti‑IgE (for allergic asthma phenotypes).
- Tezepelumab (Amgen/AstraZeneca): anti‑TSLP (works more broadly across asthma phenotypes, not limited to eosinophils).
If you mean a different mepolizumab indication (for example, eosinophilic granulomatosis with polyangiitis), tell me and I’ll narrow the competitor list to that specific use.
Is benralizumab the closest “like-for-like” alternative?
Yes for mechanism and target biology. Benralizumab also controls eosinophilic inflammation, but it binds the IL‑5 receptor alpha rather than IL‑5 itself. That makes it a common direct comparator to mepolizumab in severe eosinophilic asthma treatment discussions.
Are there competitors beyond biologics (tablets/inhalers)?
For severe eosinophilic asthma, mepolizumab’s closest competitors in practice are other biologics listed above. There are also non-biologic controller options (like inhaled corticosteroids plus long-acting bronchodilators), but they aren’t IL‑5–pathway competitors in the same way.

Quick clarifying question
Do you want competitors for severe eosinophilic asthma specifically, or for another mepolizumab indication (like EGPA)?
