Aim: To examine real-world treatment patterns, survival, healthcare resource use and costs in elderly Medicare beneficiaries with diffuse large B-cell lymphoma (DLBCL). Methods: 11,880 Medicare patients aged ≥66 years with DLBCL between 1 October 2015 and 31 December 2018 were followed for ≥12 months after initiating front-line treatment. Results: Two-thirds (61.2%) of the patients received standard-of-care R-CHOP as first-line treatment. Hospitalization was common (57%) in the 12-months after initiation of 1L treatment; the mean DLCBL-related total costs were US$84,416 during the same period. Over a median follow-up of 2.1 years, 17.8% received at least 2L treatment. Overall survival was lower among later lines of treatment (median overall survival from initiation of 1L: not reached; 2L: 19.9 months; 3L: 9.8 months; 4L: 5.5 months). Conclusion: A large unmet need exists for more efficacious and well-tolerated therapies for older adults with DLBCL. Diffuse large B-cell lymphoma (DLBCL) is the most common form of Non-Hodgkin lymphoma, and it becomes more common with age. While researchers continue to develop newer, more effective treatments for DLBCL, it is important to understand how patients use existing treatments and the associated costs, particularly among the elderly. In our real-world analysis of nearly 12,000 older patients with DLBCL, we found high rates of hospitalization and hospice use, short length of life in later lines of therapy and substantial healthcare costs. Our findings suggest a large current unmet need for more effective and well-tolerated therapies for older adults with DLBCL in both the front-line and relapse/refractory settings. A real-world analysis of nearly 12,000 elderly patients with DLBCL observed high rates of hospitalization and hospice use, poor overall survival in later lines of therapy and substantial healthcare costs, suggesting a large unmet need.

Background: The first‐generation BTK inhibitor ibrutinib is a standard‐of‐care therapy in the treatment of chronic lymphocytic leukemia (CLL) despite potential side effects that often lead to discontinuation. Methods: This study used 2013–2019 claims data to describe the incidence rate of adverse events (AEs) among elderly Medicare beneficiaries newly initiating ibrutinib for CLL. Results: The final sample contained 11,870 Medicare beneficiaries with CLL (mean age 77.2) newly initiating ibrutinib, of whom 65.2% discontinued over mean follow‐up of 2.3 years. The overall incidence rate of AEs was 62.5 per 1000 patient‐months for all discontinuers and 32.9 per 1000 patient‐months for non‐discontinuers. Discontinuers had a higher incidence rate of AEs per 1000 patient‐months compared with non‐discontinuers for all AEs examined, including infection (22.8 vs. 14.5), atrial fibrillation (15.1 vs. 7.0), anemia (21.9 vs. 14.5), and arthralgia/myalgia (19.5 vs. 13.6). Conclusion: In this first real‐world study of a national sample of elderly US patients treated with ibrutinib, we found a clear unmet need for improved management of ibrutinib‐related AEs and/or new treatments to improve real‐world outcomes in patients with CLL.
