Summary
The aim of this study is to evaluate concordance of T790M mutation plasma testing between the Cobas test and each of other platforms: Super-ARMS, digital PCR or NGS. And to assess the efficacy of AZD9291 monotherapy by assessment of PFS in adult patients with advanced or metastatic NSCLC, who have received prior EGFR-tyrosine kinase inhibitor (TKI) therapy and are T790M mutation positive detected by any one of the four plasma testing platforms: Cobas/Super-ARMS/ digital PCR/NGS.
