How to Integrate Elotuzumab and Daratumumab Into Therapy for Multiple Myeloma

Purpose Treatment options and outcomes for patients with multiple myeloma have dramatically improved over the past decade with new agents and drug targets for patients at all stages of disease. Incorporation of newly approved monoclonal antibodies is a clinical challenge because the trials used to gain approval are relatively limited in scope and may be less helpful for patients treated in the United States. This article will review data on the use of elotuzumab and daratumumab and provide a foundation for their use in current clinical practice. Methods We performed a review of current published articles and abstract data from clinical trials as well as data on managing adverse events. Results Single-agent activity was seen when using daratumumab in refractory myeloma, and trials for both elotuzumab and daratumumab have demonstrated significant activity when combined with proteasome inhibitors and immunomodulatory agents. Unique antibody-related adverse events and challenges are reviewed and discussed. Conclusion These antibodies already have had and will continue to have a dramatic impact on myeloma treatment. Combination therapy likely represents the best approach for their use, and trials that evaluate optimal timing and duration of therapy are in progress as part of induction, salvage, and maintenance therapy.
