Introduction: Significant proportion of patients with diffuse large B-cell lymphoma (DLBCL) is refractory or relapse (R/R) after the treatment. The prognosis of this patient cohort remains poor. Novel strategies mainly based on immunotherapy and targeted agents are currently being studied. Glofitamab is novel T-cell-engaging bispecific antibody possessing a 2:1 structure with bivalent CD20 binding. Its safety and efficacy in R/R B-cell non-Hodgkin lymphoma including DLBCL were evaluated in phase I-II NP30179 trial.
Areas covered: The article summarizes the milestones and latest reports on glofitamab development in the field of B-cell lymphoma treatment.
Expert opinion: Recently, phase II part of the NP30179 study and several other reports were published proving glofitamab potential in R/R DLBCL patients. Based on the published data, glofitamab was approved by regulatory authorities worldwide for the monotherapy of R/R DLBCL in conventional time-limited manner. It is readily accessible in case of rapidly progressing disease, and it compares well with other novel treatment options. Its side effects are similar to those of other T-cell-engaging agents and can be mitigated by pretreatment with obinutuzumab or step-up dosing. Its safety profile with manageable toxicities heads the clinical development toward combination strategies and its use in earlier therapeutic phases.
