• Status: NOT_YET_RECRUITING
• Trial end date: 2026-09-30

Summary

This is a single-center, single-arm, phase II study, aiming to preliminarily explore the efficacy and safety of JS004 combined with toripalimab and chemotherapy for perioperative treatment of locally advanced thoracic esophageal squamous cell carcinoma that is resectable. The plan is to enroll 20 patients with locally advanced resectable thoracic esophageal cancer. In the neoadjuvant treatment phase, patients will receive JS004 + toripalimab + chemotherapy (paclitaxel + cisplatin) for 2 cycles. This will be followed by the surgical phase: surgery will be performed 3-8 weeks after the last dose of neoadjuvant treatment. In the postoperative maintenance treatment phase, maintenance treatment will start 4 weeks ± 7 days after surgery, but no later than 10 weeks after surgery. For patients with R0 resection confirmed by postoperative pathology, they will receive maintenance treatment with JS004 + toripalimab for up to 15 cycles. For patients with non-R0 resection, they will receive maintenance treatment with JS004 + toripalimab combined with standard radiation or chemotherapy (selected by the investigator based on esophageal cancer guidelines). During the study, the maximum number of cycles of JS004 combined with toripalimab is 17 cycles (approximately 1 year).
