Abstract This randomized, open-label, multi-center phase 2 study (ClinicalTrials.gov, number NCT03116152) assessed sintilimab, a PD-1 inhibitor, versus chemo in patients with advanced esophageal squamous cell carcinoma (ESCC) refractory to first-line (1L) chemotherapy. The primary endpoint was overall survival (OS), while exploratory endpoint was the association of biomarkers with treatment efficacy. The median OS in the sintilimab group was significantly prolonged compared with that of the chemotherapy group, (objective response rates 12.6% and 6.3 %, respectively). Incidence of treatment-related adverse events of grade 3–5 was lower with sintilimab than with chemotherapy (20.2 vs. 39.1 %). Patients with high TCR clonality and low mTBI showed the longest median OS (15.0 mo), while patients with low NLR at 6 wk post-treatment had a significantly prolonged median OS compared with those with high NLR. High expression of T-follicular helper cells or activated B-cell signature was significantly associated with longer progression-free survival in the sintilimab group.
