Neoadjuvant chemotherapy (nCT) has been the recommended treatment for locally advanced esophageal squamous cell carcinoma (ESCC). The addition of programmed cell death protein 1 (PD-1) inhibitor to nCT may improve oncologic outcome and survival. However, high-level evidence of neoadjuvant immunotherapy (nIT) combined with nCT in locally advanced resectable ESCC patients are still lacking. Hence, we describe this randomized controlled trial in order to assess the efficacy and safety of neoadjuvant nivolumab in combination with chemotherapy for locally advanced (stage II-III) ESCC patients.This prospective, randomized, multicenter phase II trial aims to enroll 90 locally advanced (stage II-III) ESCC patients who will undergo nivolumab or placebo plus chemotherapy followed by surgery. Patients will be 2:1 randomized to nivolumab/chemo and placebo/chemo group by method of stratified randomization. In both arms, patients who have not achieved complete pathological complete response (pCR) will be administered with adjuvant nivolumab for up to 1 year. The primary endpoint is pCR rate and secondary endpoints include event-free survival (EFS), R0 resection rate, and adverse events (AEs). The safety will be evaluated by AEs, grading by Common Terminology Criteria for Adverse Events (CTCAE) 5.0 classifications. The double-blind will be maintained between subjects and investigators until the final unblinding process.This protocol has been reviewed and approved by the Ethics Committee of Zhongshan Hospital (B2022-004R). This is the first prospective, multicenter, randomized controlled trial to compare the combination of immunotherapy and chemotherapy with standard chemotherapy in neoadjuvant treatment for ESCC, also to explore whether adjuvant immunotherapy offers additional benefit in non-pCR patients after nCT with/without immunotherapy and R0 resection. We hypothesize that the pCR rate, R0 resection rate, EFS and OS of the study group (nivolumab/chemo) is significantly better than those of control group.ClinicalTrial.gov: NCT05213312.2023 Journal of Thoracic Disease.
