Study of Adebrelimab Combined With Thymalfasin and Chemotherapy for Neoadjuvant Treatment of Esophageal Cancer

This is a prospective, single-arm, multicenter clinical study conducted in China. Patients with pathologically or cytologically confirmed resectable esophageal squamous cell carcinoma will be enrolled to explore the efficacy and safety of adebrelimab combined with thymalfasin and chemotherapy as neoadjuvant therapy for resectable esophageal squamous cell carcinoma. The study consists of a screening period (from the signing of informed consent by subjects to the first study drug administration, no more than 21 days), a treatment period (including neoadjuvant therapy and surgery), and a follow-up period (comprising safety follow-up and survival follow-up). During neoadjuvant therapy, patients will receive 2 to 3 cycles of adebrelimab combined with thymalfasin and chemotherapy, followed by surgical resection.
