Description
Summary:Introduction: Multiple myeloma (MM) is an incurable hematologic condition that is associated with high Tx costs. Resource consumption is driven by hospitalization and medical utilization, which is highest during periods of uncontrolled disease, such as after diagnosis and during relapses (De Portu 2013). In the pivotal phase 3 FIRST trial, continuous Tx with lenalidomide plus low-dose dexamethasone (Rd) was compared with fixed-duration Rd (Rd18) or fixed-duration combination Tx with melphalan, prednisone, and thalidomide (MPT), each for 18 months (mos), in NDMM pts who were ineligible for stem cell transplantation. Continuous Rd extended progression-free survival (PFS) and overall survival (interim analysis) vs. MPT. However, it is still unclear whether extending Tx duration with Rd adversely affects healthcare resource utilization. This analysis quantifies the rates of hospitalizations and medical utilization with continuous Rd over time based on data collected in the FIRST trial. Methods: The FIRST trial (N = 1,623) was a pivotal multinational, randomized, open-label study with a median follow up of 37 mos. Non-protocol-driven resource-use data was collected until subjects discontinued study Tx. To assess whether continuous Rd increases healthcare resource utilization over time, the rates of resource utilization for subjects treated with continuous Rd (N = 535) were plotted for up to 48 mos. In addition, hospitalization and medical utilization rates during the Tx period (18 mos) were estimated and compared between the 2 fixed-duration Tx arms. Results: Resource utilization amongst pts treated with continuous Rd declined over time (Figure). The annualized hospitalization rate in the first 3 mos was 3.2 times higher than the average rate for the remaining 45 mos of follow-up (2.02 vs. 0.62), and 4.2 times higher for medical utilization (5.66 vs. 1.34). After 4 years (yrs) of continuous Rd Tx, hospitalization and medical utilization rates were estimated to be 83% and 84% lower than those observed in the first 3 mos of Tx, reflecting the long-term disease control observed with continuous Rd in the FIRST trial. The highest hospitalization rates were associated with infections (0.20 per patient year), cardiovascular disorders (0.06), and respiratory and thoracic disorders (0.05). The mean (standard deviation) length of stay per admission was 14.08 (21.19) days. The highest medical utilization rates were associated with blood transfusions (0.76 interventions pe
