简要总结
The primary goal is to evaluate the efficacy of osimertinib (AZD9291), in terms of the objective response rate in patients with advanced non-squamous NSCLC with EGFR mutations and the EGFR T790M mutation at diagnosis as defined by RECIST 1.1 criteria.
Safety and efficacy will also be measured.
详细描述
Naïve patients ≥ 18 years of age with histological confirmation of locally advanced or metastatic, non-squamous non-small cell lung cancer (NSCLC) with an activating EGFR mutation and concomitant T790M mutation. Evidence of measurable or evaluable metastatic disease is required.
Primary objective:
- To evaluate the efficacy of osimertinib (AZD9291), in terms of the objective response rate in patients with advanced non-squamous NSCLC with EGFR mutations and the EGFR T790M mutation at diagnosis as defined by RECIST 1.1 criteria.
Secondary objectives:
- To determine the safety and tolerability profile of osimertinib (AZD9291), measured using the number and severity of AEs entered into the Case Report Form (CRF); chemistry, blood count, vital signs, physical examination, weight, ECG and performance status (S).
- To determine other efficacy parameters such as progression-free survival (PFS), overall survival (OS), time to treatment failure (TTF), duration of response (DOR), disease control rate (DCR), and tumor shrinkage (TS).
- To correlate the parameters of clinical response efficacy documented with the EGFR mutational status.
- To carry out a longitudinal analysis of EGFR mutations (including the T790M mutation) in plasma and serum.
- To determine levels of BIM mRNA as well as mRNA levels of other biomarkers related to EGFR TKI response and determine whether they are predictors of treatment response.
- To identify mechanisms of acquired resistance to osimertinib (AZD9291); mutations at the site of covalent binding to the drug (C797) or other mutations in tissue or blood.

排除标准
