Study to assess the effect of AZD9291 on the blood levels of Rosuvastatin, in patients with EGFRm+ non-small cell lung cancer

This is a Phase I, open-label, 2-part study in patients with a confirmed diagnosis of epidermal growth factor receptor (EGFR) mutation positive (EGFRm+) non-small cell lung cancer (NSCLC), who have progressed following prior therapy with an approved EGFR tyrosine kinase inhibitor (TKI) agent. Part A will assess the effect of AZD9291 on the pharmacokinetic (PK) parameters of rosuvastatin, following multiple oral dosing of AZD9291 in the fasted state. Part B will allow patients further access to AZD9291 after the PK phase (Part A) and will provide for additional safety data collection. All patients from Part A who completed treatment may continue to receive AZD9291 80 mg once daily as a single agent until: disease progression; they are no longer deriving clinical benefit; or any other reason.
