Lenalidomide maintenance post-transplantation in newly diagnosed multiple myeloma: real-world outcomes and costs.

Abstract

Aim: To compare real-world outcomes and costs among patients with newly diagnosed multiple myeloma receiving lenalidomide-only maintenance (Len-Mt) versus no maintenance after autologous hematopoietic stem cell transplantation. Patients & methods: Time to next treatment (TTNT) was evaluated; costs were calculated for 0-12, 12-24 and 24-36 months postindex date. Results: Len-Mt cohort had longer TTNT (HR: 0.43; p < 0.0001). Per-patient per-month costs during months 0-12 were higher among patients, receiving Len-Mt (USD 13,095 vs USD 8910; p < 0.0001), due to higher pharmacy costs - outpatient costs were lower. During months 12-24 and 24-36, outpatient costs were similar in both cohorts; total and pharmacy costs remained elevated for patients receiving Len-Mt. Conclusion: Len-Mt improved TTNT, initially reduced outpatient costs, but resulted in higher overall and pharmacy costs.
