Cost-effectiveness analysis for midostaurin versus standard of care in acute myeloid leukemia in the United Kingdom

AIMS: Midostaurin (MIDO) has been proposed for the treatment of newly-diagnosed adult patients with FMS-like tyrosine kinase 3 mutation-positive (FLT3+) acute myeloid leukemia (AML) in combination with standard chemotherapy. The cost-effectiveness of MIDO and standard of care (SOC) followed by MIDO...

Sumario:AIMS: Midostaurin (MIDO) has been proposed for the treatment of newly-diagnosed adult patients with FMS-like tyrosine kinase 3 mutation-positive (FLT3+) acute myeloid leukemia (AML) in combination with standard chemotherapy. The cost-effectiveness of MIDO and standard of care (SOC) followed by MIDO monotherapy was compared to SOC alone for newly-diagnosed FLT3+ AML in the UK. METHODS: A partitioned survival model was developed from a UK public healthcare system perspective to compare the cost-effectiveness of MIDO plus SOC and SOC over a lifetime horizon. The model included the following health states/partitions: induction, consolidation, monotherapy, complete remission (CR), relapse, stem cell transplantation (SCT), SCT recovery, and post-SCT recovery. Data on CR, overall survival, and adverse events were obtained from a Phase III clinical trial. Overall survival was extrapolated beyond the trial horizon using a ‘cure model’ approach and data from the Office for National Statistics. Utilities were identified via a systematic review. Routine care utilization was obtained from the National Institute for Health and Care Excellence single technology appraisal for azacitidine in AML (TA399). The costs of drugs and administration, adverse events, hospitalizations, physician visits, and end-of-life care were incorporated. RESULTS: Incremental life years (LYs) and quality-adjusted life years (QALYs) gained by patients on MIDO and SOC versus SOC were 1.67 and 1.47, respectively. At an incremental cost of £54,072 over a lifetime horizon, the ICER was £32,465 per LY and £36,826 per QALY. Sensitivity analyses were generally consistent with the base case findings. CONCLUSIONS: With limited treatments in FLT3+ AML, MIDO represents a clinically significant advance in the management of newly-diagnosed AML. Using a threshold of £50,000 per QALY for end-of-life treatment, MIDO was shown to be a cost-effective option for newly-diagnosed FLT3+ AML.
