The patients were randomly assigned, in a 1:1 ratio, to receive sac-TMT monotherapy or pemetrexed plus platinum-based chemotherapy. The primary end point was progression-free survival as assessed by blinded independent review. Overall survival was a hierarchically tested key secondary end point. In the interim analysis of progression-free survival as assessed by blinded independent review, sac-TMT monotherapy met the prespecified criterion for significance (two-sided P<0.0001); we report here the prespecified final analysis of progression-free survival and the preplanned interim analysis of overall survival.\n\nResults: Overall, 376 patients underwent randomization, with 188 assigned to each group. After a median follow-up of 18.9 months, the median progression-free survival was 8.3 months in the sac-TMT group and 4.3 months in the chemotherapy group (hazard ratio for disease progression or death, 0.49; 95% confidence interval [CI], 0.39 to 0.62). Overall survival was significantly longer with sac-TMT than with chemotherapy (hazard ratio for death, 0.60; 95% CI, 0.44 to 0.82; two-sided P = 0.001); 18-month overall survival was 65.8% and 48.0%, respectively. Treatment-related adverse events of grade 3 or higher occurred in 58.0% of patients receiving sac-TMT and in 53.8% of those receiving chemotherapy, with the most common being a decreased neutrophil count (39.9% vs. 33.0%); treatment-related serious adverse events occurred in 9.0% and 17.6%, respectively.\n\nConclusions: In patients with EGFR -mutated advanced or metastatic NSCLC that had progressed after previous EGFR-TKI therapy, progression-free survival and overall survival outcomes were significantly better with sac-TMT than with platinum-based chemotherapy.
