Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This is a prospective, open label, multi-centre single arm phase II study assessing the efficacy and safety of AZD9291 monotherapy in patients with stage IIIB or IV harboring sensitising EGFR mutation (exon 19 deletions or exon 21 L858R substitution mutations) and T790M who have progressed following prior treatment with an approved EGFR TKI. Approximately 106 subjects will be enrolled.
All patients must have documented radiological progression on EGFR-TKI treatment and on the last treatment administered prior to enrolling in the study.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
AZD9291 is an oral, potent, irreversible EGFR-TKI selective for sensitizing (EGFRm) and T790M resistance mutation with a significant selectivity margin against wild-type EGFR. As a result, AZD9291 can effectively block EGFR signaling both in EGFR single mutant cells with activating EGFR mutations and in double mutant cells bearing the resistance T790M mutation.
This is a prospective, open label, multi-centre single arm phase II study assessing the efficacy and safety of AZD9291 monotherapy in patients with stage IIIB or IV harboring sensitising EGFR mutation (exon 19 deletions and exon 21 L858R substitution mutations) and T790M who have progressed following prior treatment with an approved EGFR TKI. Approximately 108 subjects will be enrolled.
All patients must have documented radiological progression on EGFR-TKI treatment and on the last treatment administered prior to enrolling in the study.
Target patient population:
Patients will be \> 18 years of age, with a diagnosis of locally advanced/metastatic NSCLC not amenable to curative surgery or radiotherapy with documented activating EGFR mutations (exon 19 deletions and exon 21 L858R substitution mutations) at the time of initial diagnosis, have radiological disease progression following either 1st line EGFR TKI treatment OR following prior therapy with an EGFR TKI and a platinum-based doublet chemotherapy. Plasma sample must harbour an EGFR mutation known to be associated with EGFR TKI sensitivity (exon 19 deletion, L858R as well as presence of T790M by central lab testing from a plasma sample taken after confirmation of disease progression on the most recent treatment regimen. Patients must have normal organ and bone marrow function and ECOG PS 0-2.
Treatment and regimens:
Patient will be treated with AZD9291 at a starting dose of 80mg once a day until the patient completes the study, withdraws from the study or closure of the study. A cycle of treatment is defined as 28 days of once daily AZD9291 treatment. Patients may continue to receive AZD9291 until objective disease progression (determined by RECIST 1.1) or if the subject is no longer receiving clinical benefit in the Investigator's opinion.
