Us Cost Burden Of Relapsed Refractory Multiple Myeloma During Third And Later Lines Of Treatment

Background: Several novel therapies for multiple myeloma (MM) have been approved in recent years. While these therapies have demonstrated improvement in real-world tumor responses and progression-free survival, the cost burden of late-line relapsed refractory MM is not well understood. The objective of this retrospective cohort analysis of US claims data was to examine total, MM-related, and adverse event (AE)-related healthcare costs for patients with MM at different lines of treatment (LOTs), with a focus on patients at third (3L) or later (4L+) LOT.
