Neoadjuvant Comprehensive Treatment for Unresectable Esophageal Cancer
Recruiting now · Phase 2
Conditions studied: Esophagus Cancer
In brief
Patients diagnosed with locally advanced esophageal squamous cell carcinoma (ESCC) that is deemed unresectable face a bleak prognosis. Recent phase 1/2 studies have demonstrated the efficacy and safety of augmenting neoadjuvant concurrent chemoradiotherapy with immunotherapy in treating resectable ESCC. The present study is a prospective, 3-arm, randomized trial that seeks to evaluate the efficacy of diverse conversion therapy modalities in patients with unresectable ESCC. The study objectives include R0 resection rate, treatment-related adverse events, morbidity and mortality, 1-year progression-free survival (PFS), and 1-year overall survival (OS) rates. Tislelizumab is a humanized IgG4 monoclonal antibody with high affinity/specificity for programmed cell death protein 1 (PD-1). Tislelizumab was specifically engineered to minimize binding to FcɤR on macrophages, thereby abrogating antibody-dependent phagocytosis, a potential mechanism of T-cell clearance and resistance to anti-PD-1 therapy. This trial will provide valuable insights into the effectiveness of the three conversion therapy modalities and help to inform clinical decision-making for patients with unresectable locally advanced ESCC.
