ATCC and the Broad Institute report the development of engineered isogenic cancer models designed to replicate resistance to targeted therapies, beginning with osimertinib, the latest-generation epidermal growth factor receptor (EGFR) inhibitor used to treat non-small cell lung cancer (NSCLC) with EGFR mutations.
According to the researchers, the work addresses a critical challenge in oncology—treatment resistance that emerges over time. EGFR-mutant lung cancer was among the first subsets of a major epithelial cancer where directly targeting an oncogene was associated with marked clinical benefit. While targeted therapies have significantly improved overall survival, resistance inevitably develops.
Developing resistant models directly from patient tumors can take years due to the scarcity of samples. In contrast,…
