E.5 End points |
E.5.1 | Primary end point(s) |
Progression-free survival (PFS) using Investigator assessment as defined by RECIST 1.1.
Progression-free survival (PFS) is defined as the time from randomization until the date of objective disease progression or death (by any cause in the absence of progression), regardless of whether the patient withdraws from randomized therapy or receives another anti-cancer therapy prior to progression. Patients who have not progressed or died at the time of analysis will be censored at the time of the latest date of assessment from their last evaluable RECIST assessment.
The primary efficacy analysis of progression-free survival will be performed by investigator assessment (RECIST 1.1). An additional sensitivity analysis will be performed for PFS by BICR assessment. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The primary analysis of PFS based on investigator assessment will occur when approximately 280 progression events have been observed in the 556 globally randomized patients (approximately 50% maturity). |
|
E.5.2 | Secondary end point(s) |
1. OS; Landmark OS at 1, 2, and 3 years; ORR, DoR; depth of response; DCR by Investigator
2. PFS2; TFST; TSST
3. Change from baseline in EORTC QLQ-C30; Change from baseline in EORTC QLQ-LC13
4. Steady-state plasma concentrations and appropriate PK parameters (CLss/F, Cmax,ss Cmin,ss and AUCss) of osimertinib and its metabolite, AZ5104 will be summarized.
5. Concordance of EGFR mutation status between the local EGFR mutation test and the central cobas® EGFR Mutation Test v2 results from tumor samples with evaluable results.
6. PFS by Investigator by plasma EGFR mutation status. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
OS will be tested at the PFS analysis and when the OS data are approximately 60% mature (approximately 334 death events across both arms). |
