Current management and emerging treatment strategies for multiple myeloma.

Abstract

Multiple myeloma is a malignant plasma cell neoplasm that is incurable despite significant progress in treatment over the past several decades. The incorporation of novel agents and combinations into the MM treatment paradigm has resulted in improved survival and tolerability, as well as deeper responses including achieving a minimal residual disease negative state. The addition of new treatment options and combinations has added complexity in treatment selection for myeloma patients. The current strategy for newly diagnosed myeloma involves induction, consolidation, and maintenance therapy. However, nearly all myeloma patients will develop refractory disease. This highlights the need for more effective therapies targeting the myeloma cells and their microenvironment. In this article, we summarize current management of transplant eligible and ineligible newly diagnosed patients in both the upfront and relapsed refractory setting, highlighting risk adapted strategies. We also summarize emerging therapies, such as immune and targeted approaches, as well as drugs with novel mechanisms of action. Emerging strategies offer individualized treatment options and may ultimately offer the possibility of a cure for myeloma patients.
