This a phase III, Multi Centre, Open Label, Randomized, Study to Assess the Efficacy and Safety of AZD9291 (80 mg, orally, once daily) in Combination with MEDI4736 (10 mg/kg (IV) infusion q2w) versus AZD9291 Monotherapy (80 mg, orally, once daily) in patients with a confirmed diagnosis of Epidermal Growth Factor Receptor (EGFR) T790M mutation positive NSCLC, who have progressed following prior therapy with an approved Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor (EGFR-TKI) agent. The randomization will be stratified by previous lines of treatment (2nd or 3rd+) and ethnicity (Asian or Non-Asian). A mandatory biopsy will be needed for central testing of T790M mutation status following confirmed disease progression on the most recent treatment regimen. The primary objective of the study is To investigate the safety and tolerability profile of AZD9291 in combination with MEDI4736.~350 patients were originally planned to be evaluated across the two below populations. The recruitment was stopped due to new information on safety of the combination, received from another trial in similar patient population~2nd line: patients who have progressed following an approved first-line EGFR-TKI treatment but who have not received further treatment.~3rd line or higher: patients who have progressed following prior therapy with an approved EGFR-TKI and an additional anti-cancer treatment. Patients may have also received additional lines of treatment.
A Phase III, Multi-Centre, Open Label, Randomized Study to Assess the Efficacy and Safety of AZD9291 in Combination with MEDI4736 versus AZD9291 Monotherapy in patients with Locally Advanced or Metastatic Epidermal Growth Factor Receptor T790M mutation-positive Non-Small Cell Lung Cancer who have received Prior Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor Therapy
