Abstract:
Sevabertinib (HYRNUO®), an oral, reversible, small molecule tyrosine kinase inhibitor (TKI) of human epidermal growth factor receptor 2 (HER2) that also shows activity against epidermal growth factor receptor (EGFR), is being developed by Bayer for the treatment of solid tumours with mutations in HER2 or EGFR genes. Sevabertinib is derived from Bayer's strategic research alliance with the Broad Institute of MIT and Harvard. In November 2025, sevabertinib was approved under accelerated approval in the USA for use in adults with locally advanced or metastatic non-squamous non-small cell lung cancer (NSCLC) whose tumours have HER2 (ERBB2) TK domain (TKD) activating mutations, as detected by an FDA-approved test, and who have received a prior systemic therapy. This article summarizes the milestones in the development of sevabertinib leading to this first approval for the treatment of locally advanced or metastatic NSCLC with HER2 (ERBB2) activating mutations.
Insights
Sevabertinib is a new targeted therapy for non-small cell lung cancer (NSCLC) with specific HER2 mutations. It received accelerated approval in the USA for adults with advanced NSCLC after prior treatment.
Area of Science:
- Oncology
- Pharmacology
- Molecular Biology
Background:
- Sevabertinib is an oral, reversible small molecule tyrosine kinase inhibitor (TKI).
- It targets human epidermal growth factor receptor 2 (HER2) and epidermal growth factor receptor (EGFR).
- Developed by Bayer, it stems from a research alliance with the Broad Institute.
Purpose of the Study:
- To summarize the development milestones of sevabertinib.
- To highlight its first approval for treating specific non-small cell lung cancer (NSCLC) cases.
Main Methods:
- Review of development history and regulatory submissions for sevabertinib.
- Analysis of its mechanism of action as a HER2/EGFR inhibitor.
Main Results:
- Sevabertinib received accelerated approval in the USA in November 2025.
- Approval is for adults with locally advanced or metastatic non-squamous NSCLC.
- Treatment is indicated for tumors with HER2 (ERBB2) TK domain activating mutations and prior systemic therapy.
Conclusions:
- Sevabertinib represents a significant advancement in targeted therapy for NSCLC.
- Its approval addresses a critical unmet need for patients with HER2-mutated NSCLC.
- This milestone facilitates personalized treatment strategies in oncology.
