Glofitamab in relapsed/refractory diffuse large B cell lymphoma: Real world data

Abstract

Abstract INTRODUCT ̇ION Glofitamab is a T-cell-engaging bispecific antibody connecting CD20 on B cells and CD3 on T cells. Although, most of the patients with B-cell non-Hodgkin lymphoma (BNHL) achieve complete response (CR) following firstline treatment with rituximab and chemotherapy, about 40% of patients with diffuse large B-cell lymphoma (DLBCL) is refractory or relapse (R/R). Autologous stem-cell transplantation (ASCT) can cure some of these patients but many patients cannot undergo this procedure. CAR-T therapies are a significant advance but not available in many countries like Turkey. In Phase II expansion study, the overall response rate (ORR) was 51.6% and complete remission (CR) rate was 39.4% in R/R DLBCL patients (Dickinson er al. JCO 2022). In this retrospective study, we aimed to report the outcomes of patients who used glofitamab via compessionate use in Turkey.
