Advances in targeted therapy for the treatment of patients with relapsed/refractory multiple myeloma

Abstract

The development of proteasome inhibitors (PIs) and immunomodulatory drugs has significantly improved outcomes for patients with relapsed/refractory multiple myeloma (RRMM); however, not all patients benefit from treatment with these agents and some patients can become drug refractory over time. Due to the largely incurable nature of multiple myeloma, the development of newer agents is ongoing and includes new oral PIs (ixazomib), immunotherapies (e.g., CD38- or SLAMF7-targeted antibodies), and small molecules. This review provides an overview of the advances in targeted therapy for patients with RRMM, including recently approved agents, with a focus on monotherapy and combined targeted therapies.
