Abstract

BACKGROUND:

Two basal insulin analogues, insulin glargine once daily and insulin detemir once or twice daily, are marketed in Canada.

OBJECTIVE:

To estimate the long-term costs of insulin glargine once daily (QD) versus insulin detemir once or twice daily (QD or BID) for type 1 (T1DM) and type 2 (T2DM) diabetes mellitus from a Canadian provincial government's perspective.

METHODS:

A cost-minimization analysis comparing insulin glargine (IGlarg) to insulin detemir (IDet) was conducted using a validated computer simulation model, the CORE Diabetes Model. Lifetime direct medical costs including costs of insulin treatment and diabetes complications were projected. T1DM and T2DM patients' daily insulin dose (T1DM: IGlarg QD 26.2 IU; IDet BID 33.6 IU; T2DM: IGlarg QD 47.2 IU; IDet QD 65.7 IU or IDet BID 80.4 IU) was derived from a meta-analysis of randomized trials. All patients were assumed to stay on the same treatment for life. Costs were discounted at 5% per annum and reported in 2010 Canadian Dollars.

RESULTS:

The meta-analysis showed T1DM and T2DM patients had similar HbA(1c) change from baseline when receiving IGlarg compared to IDet (T1DM: 0.002%-points; p = 0.97; T2DM: -0.05%-points; p = 0.28). Treatment of T1DM patients with IGlarg versus IDet BID resulted in lifetime cost savings of $4231 per patient. Treatment of T2DM patients with IGlarg resulted in lifetime cost savings of $4659 per patient versus IDet QD and cost savings of $8709 per patient versus IDet BID.

CONCLUSIONS:

Similar HbA(1c) change from baseline can be achieved with a lower IGlarg than IDet dose. From the perspective of a Canadian provincial government, treatment of T1DM and T2DM patients with IGlarg instead of IDet can generate long-term cost savings. Main limitations include trial data were derived from multi-country studies rather than the Canadian population and self-monitoring blood glucose costs were not included.
