ABSTRACT
Background: The introduction of daratumumab into the treatment of multiple myeloma has improved outcomes in patients; however, community oncologists often dose more frequently than the US FDA-approved label. Materials and methods: Integra analyzed its database to elucidate daratumumab treatment patterns and the impact of increased utilization on the cost of care for multiple myeloma. Results: Following week 24, 671 (65%) of 1037 patients remained on daratumumab-containing regimens, with 330 patients continuing more frequent treatments than the expected once-every-4-weeks dosing described in the standard dosing schedule. Patients received an average of 14% more daratumumab doses than the FDA-approved label indicates, increasing the 1-year daratumumab costs by an estimated US$31,353. Conclusion: Daratumumab is utilized more frequently than the FDA-recommended dosing, leading to higher multiple myeloma treatment costs.
Lay abstract Since its first approval in 2015, daratumumab has become the backbone of many multiple myeloma treatment regimens. While its approval has improved outcomes in many patients who undergo treatment, it is expensive and has largely contributed to the increasing costs of care in multiple myeloma. In its most common treatment schedule, patients should transition from weekly and biweekly dosing to treatment once every 4 weeks. However, many providers maintain their patients on a more frequent dosing schedule, which increases Medicare 1-year costs by an estimated US$31,353 and may have unforeseen impacts on adverse events and patient outcomes.

The care of patients with HIV and Burkitt lymphoma poses a challenge to clinicians. Due to the limited treatment options that exist for relapsed/refractory Burkitt lymphoma, there is a need for the development of new therapies. This review aims to discuss evidence for current management strategies including chemotherapy and stem cell transplant, and highlight gaps in knowledge that will need to be addressed in the future.
