Overview
Brief Summary
The purpose of this study is to evaluate the efficacy and safety of Sintilimab in combination with Pegaspargase and anlotinib in the treatment of stage IV NK/T-cell lymphoma patients unfit for high-dose chemotherapy.
Detailed Description
Stage IV NK/T-cell lymphoma has a poor prognosis, and autologous hematopoietic stem cell transplantation can improve the prognosis of patients who have achieved remission after chemotherapy. The median survival time for patients who were not suitable for transplantation was about 1 year. Asparaginase is the backbone drug for the treatment of NK/T-cell lymphoma. PD-1 antibody is effective for relapsed/refractory NK/T-cell lymphoma. Our previous study found that anlotinib is active in relapsed/refractory NK/T Cell lymphoma. This study is aimed to investigate the efficacy and safety of Sintilimab, a PD-1 antibody approved in China, in combination with Pegaspargase and anlotinib in the treatment of stage IV NK/T-cell lymphoma patients unfit for high-dose chemotherapy.
