Deferasirox dominatesdeferoxamine for iron control

Deferasirox represents a "cost-effective use ofresources" in the UK for iron control in patients with ironoverload resulting from frequent blood transfusions, sayresearchers from that region.

They built an economic model using data obtainedfrom clinical trials to assess the cost effectiveness of oraldeferasirox ≥ 20 mg/kg/day versus standard ironchelation therapy with an equivalent dose ofSC deferoxamine (≥ 35 mg/kg/day) in paediatric andadult patients with chronic iron overload due to frequentblood transfusions.* A time horizon of 1 year wasadopted, and costs were calculated from the perspectiveof the UK NHS.

The drug dose and cost was patient-weight related,and in the reference case considering patients with amean weight of 42kg, deferasirox would dominatedeferoxamine, being both less costly and resulting inmore QALYs gained (difference of 0.176 QALYs).Deferasirox would also dominate among patientsweighing a mean of 52kg. For patients weighing meansof 62kg and 72kg, deferasirox would cost £7775 perQALY gained and £16 720 per QALY gained,respectively, compared with deferoxamine.

Sensitivity analysis incorporating joint uncertainty inadministration cost and other variables estimated thatdeferasirox would have an 80% probability of beingcost effective at a willingness-to-pay value of £20 000/QALY gained.* Financial sponsorship from Novartis was received for this study.
