NeoSCORE II: three vs four cycles of neoadjuvant sintilimab + chemotherapy for squamous non-small-cell lung cancer.

Immune checkpoint inhibitors (ICIs) plus chemotherapy has demonstrated efficacy in resectable non-small-cell lung cancer (NSCLC), yet the optimal period of neoadjuvant immunochemotherapy is undetermined. In a phase II study (neoSCORE, NCT04459611), more neoadjuvant therapy cycles appeared to provide greater pathological remission, and patients with squamous NSCLC had a better major pathological response rate than those with nonsquamous NSCLC. Sintilimab, a monoclonal anti-PD-1 antibody, has shown encouraging antitumor activity and safety in multiple cancers, including NSCLC. Here, we describe the study design of neoSCORE II (NCT05429463), a randomized, open-label, multicenter phase III trial comparing the efficacy and safety of three cycles with four cycles of neoadjuvant sintilimab plus platinum-based chemotherapy in resectable stage IIA–IIIB squamous NSCLC.
