Resumen
Fecha de inicio: 25 de marzo de 2022
Fecha en la que se inscribió al primer participante.This study is a randomized, open, multicenter clinical study to determine whether the addition of sindilizumab to the R-CHOP regimen could improve the objective efficiency of DLBCL patients with P53 mutation with PD-L1 expression and to see if it could prolong patient survival.In this study, patients with P53 mutation with PD-L1 expressing DLBCL were selected to be randomised 1:1 into 2 groups: group A Sindilizumab + R-CHOP and group B R-CHOP. Sindilizumab was administered on day 10 after chemotherapy to avoid interference from prednisone.At the end of 6 cycles, Group A treatment effective maintenance treatment with Sindilizumab for 6 months as indicated.Each patient's tumour tissue was tested for mutations and ctDNA after allocation, and ctDNA and peripheral blood free PD-L1 levels were monitored dynamically during and after treatment.
