Title Neoadjuvant sintilimab plus chemotherapy in early-stage EGFR-mutant NSCLC: phase 2 trial interim results (NEOTIDE/CTONG2104)
Organism Homo sapiens
Experiment type Expression profiling by high throughput sequencing
Summary We launched an investigator-initiated, Simon’s two-stage design trial of neoadjuvant sintilimab combined with carboplatin and nab-paclitaxel (nab-PC) in early-stage EGFR-mutant NSCLC ( number NCT05244213). Here we report the first interim results of stage 1 cohort which met the overall primary endpoint in advance, and multi-omics profiling of neoadjuvant immunotherapy combination in early-stage EGFR-mutant patients. We performed in-depth single-cell RNA/TCR sequencing (scRNA/TCR-seq) of cells derived from 11 resected tumors as well as 34 tumors from real-world cohort which were all confirmed wild-type lung adenocarcinoma (LUAD) or adeno-squamous carcinoma (ASC) and received neoadjuvant immunochemotherapy as control. By associating the tumor microenvironment (TME) and with responses, we uncovered heterogeneous mechanisms of primary resistance, providing insights into further strategic developments of combination regimens to improve the clinical outcome of EGFR-mutant NSCLC patients.
Overall design Non-erythrocytic living cells of 11 EGFR-mutant non-small cell lung cancer (NSCLC) and 34 wild-type lung adenocarcinoma (LUAD) or adeno-squamous carcinoma (ASC) that received neoadjuvant immunochemotherapy were isolated by gating 7AAD−CD235a− cells using Fluorescence-activated cell sorting (FACS), and analyzed using scRNA/TCR-seq.
