Becotatug Vedotin Plus Tislelizumab and Low-Dose Lenvatinib for Advanced Esophageal Squamous Cell Carcinoma, Phase II

Summary

Immunotherapy combined with chemotherapy has become the first-line standard of care for advanced esophageal squamous cell carcinoma (ESCC), significantly improving patient survival. However, with the widespread adoption of first-line immunotherapy, most patients eventually develop immune resistance. After first-line treatment failure, there is currently no established standard effective therapy for second-line ESCC. Therefore, more effective and safer treatment options are urgently needed for second-line advanced ESCC. This is a prospective, single-arm, single-center, open-label, Phase II clinical study aiming to evaluate the efficacy and safety of Becotatug Vedotin combined with Tislelizumab and low-dose Lenvatinib in patients with advanced ESCC who have failed first-line therapy. Eligible patients will receive Becotatug Vedotin combined with Tislelizumab and low-dose Lenvatinib. The primary endpoint is objective response rate (ORR) assessed per RECIST v1.1. Secondary endpoints include progression-free survival (PFS), disease control rate (DCR), duration of response (DOR), overall survival (OS), and safety.
