Osimertinib (AZD9291) is a third-generation, potent, selective and irreversible inhibitor of the epidermal growth factor receptor (EGFR) tyrosine kinase bearing mutations which either sensitise the receptor, or cause drug resistance (eg the T790M mutation) [2]. The compound is less effective against the wild-type receptor.
This compound is included in AstaZeneca's Open Innovation Pharmacology Toolbox. There are reports of acquired resistance to osimertinib with tumours developing the C797S [5,8] and L718Q mutations [1] .

Third-generation mutant EGFR inhibitors are being developed to circumvent dose-limiting WT EGFR-driven toxicities such as gastrointestinal toxicity and rash. The progress being made in developing advanced generation EGFR inhibitors is discussed by Yu and Riely (2013) [7] and Ou and Soo (2015) [4].
