Surufatinib (HMPL-012, previously named sulfatinib) is a small-molecule inhibitor targeting vascular endothelial growth factor receptors, fibroblast growth factor receptor 1 and colony-stimulating factor 1 receptor. A multi-center , opened, Phase II study have identified the efficacy and safety of Surufatinib in advanced medullary thyroid Carcinoma ( MTC) and iodine-refractory differentiated thyroid carcinoma (DTC).Toripalimab is a humanized immunoglobulin (Ig) G4 monoclonal antibody directed against the negative immunoregulatory human cell surface receptor programmed cell death 1 (programmed death-1; PD-1), with potential immune checkpoint inhibitory and antineoplastic activities. In the present study, we design a single-arm, single center Phase II trial to evaluate the efficacy and safety of the combination of Surufatinib wiht Toripalimab in locally advanced differentiated thyroid cancer as neoadjuvant therapy.
This study is designed to evaluate the efficacy and safety of the combination of Toripalimab and Surufatinib for Locally Advanced Thyroid Cancer.
