Patients with resectable stage II-IIIB EGFR (AJCC 8th edition) mutant NSCLC were enroled and received neoadjuvant sintilimab (200 mg) plus carboplatin (area under the curve 5) and nab-paclitaxel (260 mg/m2) for 3 cycles. Patients in stage II cohort received adjuvant osimertinib for up to 2 years while observation for stage I cohort...provided PD-1 regimen (sintilimab), participant compensation and insurance.

Here, we report interim results of a Simon's two-stage design, phase 2 trial using neoadjuvant sintilimab with carboplatin and nab-paclitaxel in resectable EGFR-mutant NSCLC. Informed circulating tumor DNA (ctDNA) detection in EGFR-mutant NSCLC could help identify patients nonresponsive to neoadjuvant immunochemotherapy. These findings provide supportive data for the utilization of neoadjuvant immunochemotherapy and insight into immune resistance in EGFR-mutant NSCLC.
