## TL;DR

AstraZeneca's EGFR×c-MET bispecific ADC, the most advanced in the most crowded next-generation ADC target pair.

## Summary

Tilatamig samrotecan is AstraZeneca's bispecific antibody-drug conjugate that binds both EGFR and c-MET and delivers the topoisomerase I inhibitor AZ14170133 through a cleavable linker. Its low-affinity EGFR arm and high-affinity c-MET arm mean avidity biases delivery toward tumour cells co-expressing both receptors and spares normal tissue that expresses EGFR alone. It is in phase 2 in EGFR-mutant NSCLC after osimertinib and in EGFR-wild-type NSCLC, per AstraZeneca's 2026 pipeline, and is also being explored in head and neck cancer. Stomatitis, nausea, fatigue and neutropenia are the reported toxicities, and dose optimisation on an every-3-weeks schedule is under way. It is the most advanced of roughly 24 c-MET×EGFR ADC candidates, so its results will shape a crowded field. It is a two-address ADC meant to hit lung cancers carrying both EGFR and c-MET while sparing normal cells.
