Sunvozertinib

**Semantic type:** Pharmacologic Substance

**Definition:** An orally available, irreversible, dual kinase inhibitor of epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER2) that shows similar activity against certain activating mutations, including exon 20 insertions (exon20ins), with potential antineoplastic activity. Upon oral administration,sunvozertinib binds to and inhibits EGFR and HER2, which may result in the inhibition of tumor growth and angiogenesis, and tumor regression in EGFR/HER2-expressing tumors. EGFR and HER2 are receptor tyrosine kinases that play major roles in tumor cell proliferation and tumor vascularization. In contrast to other agents active against exon20ins mutations, sunvozertinib appears to be more selective against mutated EGFR than wild-type (wt) EGFR. This may lessen wtEGFR-related dose-limiting toxicity and may allow for the administration of the desired therapeutic dose of sunvozertinib.
