What Is Zegfrovy (Sunvozertinib)?
Zegfrovy is an oral EGFR tyrosine kinase inhibitor (TKI) specifically designed for NSCLC with EGFR exon 20 insertions—a mutation resistant to standard EGFR inhibitors like osimertinib (Tagrisso).
Table of Contents
FDA Approval & Clinical Trial Data
- Accelerated approval granted based on response rate & durability.
- 46% overall response rate (ORR) in clinical trials.
- Median duration of response: 11+ months.
How Does Zegfrovy Work?
Zegfrovy blocks EGFR mutations, preventing cancer cell growth. Unlike older TKIs, it specifically targets exon 20 insertions, making it a breakthrough for resistant NSCLC.
Mechanism of Action
- Binds to EGFR protein on cancer cells.
- Blocks signaling that promotes tumor growth.
- Slows or stops cancer progression.
Zegfrovy Benefits for NSCLC Patients
- Higher response rate than traditional chemo.
- Oral medication (easier than IV treatments).
- Targets resistant mutations (exon 20 insertions).
Zegfrovy Side Effects
Common Side Effects
- Diarrhea (manage with hydration & anti-diarrheals)
- Skin rash & nail infections
- Fatigue & muscle pain
- Nausea & vomiting
Serious Side Effects
Lung inflammation (ILD/pneumonitis) – Seek help for shortness of breath, cough, fever.
Severe diarrhea – Can lead to dehydration.
Eye problems – Blurred vision, dry eyes.
