简要总结
This study is designed to assess the efficacy and safety of QLC5508 in patients with unresectable advanced or metastatic esophageal squamous cell carcinoma (ESCC) who have experienced disease progression following treatment with a platinum-based systemic therapy and an immune checkpoint inhibitor (ICI) compared with investigator's choice of chemotherapy (ICC).
