Surufatinib

Based on the preclinical rationale for combining surufatinib with immunotherapy, and the clinical efficacy observed with surufatinib in extensive-stage small cell lung cancer (ES-SCLC), the investigators hypothesize that incorporating surufatinib into the ADRIATIC regimen could further enhance survival in LS-SCLC. To evaluate this approach, the investigators plan to conduct a single-arm Phase II study to explore the safety and efficacy of concurrent chemoradiotherapy combined with toripalimab and surufatinib in treating LS-SCLC.

The combination of surufatinib with neoadjuvant chemo-immunotherapy and definitive concurrent chemoradiotherapy represents a promising new therapeutic strategy that may further improve the prognosis of patients with unresectable locally advanced esophageal squamous cell carcinoma (ESCC). Therefore, we propose to conduct a prospective, single-arm, phase II clinical trial to evaluate the efficacy and safety of this regimen in patients with unresectable, locally advanced ESCC.

This is a prospective, single-arm, phase II clinical study designed to evaluate the efficacy and safety of surufatinib and tislelizumab in combination with concurrent chemoradiotherapy, followed by consolidation therapy with tislelizumab plus surufatinib, in patients with unresectable, locally advanced stage III non-small cell lung cancer (NSCLC).
