The funding comes at a time when Series B deals are significantly down. Crunchbase shows that in Q1 of 2023, U.S. companies non-small cell lung cancerlow compared to the past nine quarters. The company is developing a brain-penetrant EGFR tyrosine kinase inhibitor (TKI) that targets EGFR-activating mutations in NSCLC. Licensed from partner Allist, furmonertinib is already approved in China. NSCLC is one of the most significant cancer types in the world, ArriVent’s CEO Bing Yao told BioSpace. About 10–25% of cases have an EGFR mutation.

Multiple EGFR TKIs are on the market already for NSCLC, including AstraZeneca’s Iressa and Boehringer-Ingelheim’s Gilotrif. However, EGFR mutations have emerged as a challenge for these initially highly effective drugs.EGFR EGFR NSCLC furmonertinib NSCLC BioSpace EGFR
