Abstract

Introduction Although the interaction between tumor immune microenvironment and angiogenesis has been well established, evidence supporting the chemo-free combination of immune checkpoint inhibitors plus antiangiogenic tyrosine kinase inhibitors in treatment-naive patients with advanced NSCLC is insufficient. This report provides the efficacy and safety of sintilimab combined with anlotinib as first-line therapy for advanced NSCLC from a phase 1b trial (NCT03628521).Methods Eligible patients who were treatment-naive and had unresectable stage IIIB/C or IV NSCLC without EGFR/ALK/ROS1 mutations received sintilimab (200 mg, day 1) and anlotinib (12 mg, day 1-14) every 3 weeks till disease progression or unacceptable toxicity. Baseline programmed death-ligand 1 expression and tumor mutation burden status was assessed in all patients. The primary end points were objective response rate and safety.Results A total of 22 patients received sintilimab and anlotinib. Median follow-up was 15.8 months (range: 8.3-19.3). Sixteen patients achieved confirmed partial response with an objective response rate of 72.7% (95% confidence interval [CI]: 49.8%-89.3%) and disease control rate of 100% (95% CI: 84.6%-100%). Median progression-free survival was 15 months (95% CI: 8.3 m, not reached), and the 12-month progression-free survival rate was 71.4% (95% CI: 47.2%-86.0%). The incidence rate of grade 3 or higher treatment-related adverse events was 54.5%, and grade 3 hypertension was predominant (two of 22, 9.1%). No grade 4 treatment-related adverse events were observed, and one case of grade 5 immune-related pneumonitis occurred.Conclusions To the best of our knowledge, this is the first study that assessed an anti-programmed cell death protein 1 antibody combined with a multitarget antiangiogenic tyrosine kinase inhibitor in the frontline setting for patients with NSCLC. In view of its encouraging efficacy, durability, and safety profile, sintilimab plus anlotinib represents a novel chemotherapy-free regimen in this patient population.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
