Patients with early stage non-small cell lung cancer (NSCLC) require new adjuvant therapeutic strategies to optimize their prognosis after complete surgical resection. The aim of the study was to evaluate the effect between adjuvant atilizumab therapy and optimal supportive therapy in patients following platinum-based adjuvant chemotherapy. IMpower010 is a randomized, globally multicenter, open-label Phase III study completed at 227 sites in 22 countries and territories. Eligible patients were stage IB (tumor ≥4 cm) to IIIA NSCLC aged 18 years or older and completely resectable according to the staging system (7th edition) of the International Cancer Federation and the American Joint Committee on Cancer. A total of 1 280 patients were enrolled after complete tumor resection between October 7, 2015 and September 19, 2018. 1 269 patients received adjuvant chemotherapy, of which 1 005 patients were eligible to receive randomized atilizumab (n=507) or the best supportive treatment (n=498); 495 patients in each group were treated. Patients were randomized (1:1) by permutation block method (4 blocks) to receive atilizumab adjuvant (1 200 mg every 21 days; 16 cycles or 1 year) or optimal supportive therapy (observation and periodic scanning for disease recurrence) after platinum-based chemotherapy adjuvant (1 to 4 cycles). The primary endpoint was the investigator's assessment of disease-free survival, and the grading test was performed first in the subgroup of stages II to IIIA population [≥1% tumor cells express PD-L1 (SP263))] in order, followed by all patients in stages II to IIIA, and finally the intent-to-treat (ITT) population (stages IB to IIIA). Safety was assessed in all patients randomized to receive atilizumab or optimal supportive therapy. After a median follow-up of 32.2 months (quartile interval: 27.4 to 38.3) in stage Ⅱ to ⅢA patients, atilizumab treatment increased PD-L1 expression by ≥1% of tumor cells compared with best supportive treatment in stage Ⅱ to ⅢA patients (HR=0.66; 95%CI:0.50~0.88;P=0.003 9), and all stage II to IIIA patients (0.79; 0.64 to 0.96;P=0.020) of disease-free survival. In the ITT population, disease-free survivalHR0.81 (0.67-0.99;P=0.040)。 In terms of adverse events, 53 (11%) of 495 patients experienced atilizumab-related grade 3 and 4 adverse events and 4 (1%) experienced atilizumab-related grade 5 adverse events.
