Expert Consensus on the Incorporation of Anti-CD38 Monoclonal Antibody Therapy Into the Management of Newly Diagnosed Multiple Myeloma

Multiple myeloma is a hematologic malignancy that is typically associated with recurrent relapses. There are numerous frontline treatment regimens that are highly effective for individual patients. The introduction of anti-CD38 monoclonal antibody therapy has shifted treatment decision-making in this setting, with many centers now considering the use of daratumumab as part of initial therapy regardless of patient eligibility for autologous stem cell transplantation (ASCT). Daratumumab has demonstrated clinical efficacy and acceptable toxicity in the first and later lines of therapy, increasing complexity in treatment selection and sequencing. Although daratumumab-containing regimens may not be appropriate for every patient, it is increasingly recognized that the most effective regimens should be used upfront, as high rates of attrition mean that many patients in real-world practice may see a limited number of lines of therapy.A panel of experts in multiple myeloma was convened to consider current evidence and treatment practices to inform a series of consensus statements on the optimal management of newly diagnosed multiple myeloma, including not only treatment selection, but the need for infection prophylaxis, route of administration, and mitigation of potential infusion-related reactions, among other clinical challenges.The goal of the present review article is to encapsulate these consensus statements and the rationale for their development, which altogether may help inform treatment selection and clinical decision-making in the front line.
