The epidermal growth factor receptor (EGFR) is a frequent driver of malignancy in the lung and as such, a target for EGFR inhibitors such as erlotinib (Tarceva, Roche) or gefitinib (Iressa, Astra Zeneca); unfortunately, tumors initially responsive to these agents quickly develop mutations which make them resistant. Osimertinib (Tagrisso, Astra Zeneca) was designed to overcome the most common resistance mutations and has been approved as rescue therapy for cancers that progress under… Read More
