Novel agents in relapsed/refractory diffuse large B-cell lymphoma.

Patients with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL), ineligible for or relapsing after autologous stem-cell transplant or chimeric antigen-receptor T-cell therapies have poor outcomes. Several novel agents, polatuzumab vedotin, tafasitamab, loncastuximab tesirine, and selinexor, have been approved and offer new opportunities for this difficult to treat population. Studies are evaluating combination of these agents with chemotherapy and other emerging therapies. Additionally, advances in our understanding of DLBCL biology, genetics, and immune microenvironment have allowed for the identification of new therapeutic targets like Ikaros and Aiolos, IRAK4, MALT1, and CD47 with several agents in ongoing clinical trials. In this chapter we review updated data supporting the use of the approved agents and discuss other emerging novel therapies for patients with R/R DLBCL.
