BACKGROUND: Acute leukemias (ALs), including acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL), are heterogeneous diseases characterized by different phenotypic, genetic, and molecular alterations that can guide treatment decisions. ALs harboring lysine methyltransferase 2A gene translocation (KMT2t), previously known as mixed-lineage leukemia, are associated with high rates of relapsed or refractory (R/R) disease. Revumenib, a first-in-class oral menin inhibitor, has shown improved clinical outcomes in patients with R/R KMT2At ALs.
OBJECTIVE: To estimate, using a budget impact model (BIM), the financial impact of introducing revumenib for the treatment of adult patients with R/R KMT2At ALs on the formulary of a hypothetical US 1-million-member commercial health plan.
METHODS: The BIM compared scenarios with or without revumenib and the resulting impact on commercial US third-party payers over a 3-year time horizon. Although no other therapies specifically targeted for R/R KMT2At ALs were approved during BIM development, 11 additional pharmacotherapies for R/R ALs (5 for AML and 6 for ALL, not including revumenib) were included as treatment options in the model. Clinical data included adverse event (AE) rates, duration of treatment, time to subsequent treatment, and survival outcomes. Cost inputs (USD 2024) included in the model comprised drug acquisition and administration, grade 3 or greater AEs, treatment-related supportive care and monitoring, subsequent treatment, and end-of-life costs. The differential cost per member per month (PMPM) was estimated. One-way sensitivity analyses varying the costs of drug acquisition and toxicity by ±20% and scenario analyses varying uptake of revumenib and epidemiology inputs, as well as excluding costs related to supportive care and posttreatment discontinuation, were performed.
RESULTS: An estimated 1.7 adult patients (AML, 1.1; ALL, 0.6) were treatment eligible annually. Estimated 3-year total plan costs without and with revumenib were $2,146,564 and $2,126,919, respectively, for savings of -$19,646. Including revumenib was estimated to yield a differential PMPM cost of -$0.0005 over 3 years. The total number of grade 3 or greater AEs was lower over 3 years (10.82 vs 10.99, respectively) in the plan with revumenib vs without. Sensitivity and scenario analyses validated the robustness of the model.
CONCLUSIONS: The BIM demonstrated that including revumenib in a formulary for adult patients with R/R KMT2At ALs was approximately cost neutral, offering patients access to a targeted treatment with potential for improved clinical outcomes.
