Evaluation of direct cost in case of insulin GLA-100rgine-100 switching to insulin GLA-100rgine-300 in diabetes mellitus in real clinical practice
Abstract
Insulin Glargine-300 (GLA-300) is an innovative basal analogue of insulin that has been released into the market in our country and is prescribed to patients with diabetes mellitus (DM). In the real-life practice, GLA-300 is oft en a replacement for the drug of the previous generation - Insulin Glargine-100 (GLA-100) that has been prescribed for more than 10 years and has proved its effi cacy and safety. Government pays for insulins in auctions and tenders, the cost aspects regarding the implementation of GLA-300 in practice are a current problem. According to the aggregated data on patients transferred from GL-100 to GL-300 obtained from the Federal Register of DM of the Russian Federation, the direct costs (DC) for the both types of DM were determined, considering age, complications, and achievement of the target levels of glycated hemoglobin (HbA1c). Th e drugs prices were determined on the basis of the State Register of the Price Ceiling on those medications which are included in the list of the vital and essential medicines (VED). It was found that in case of type 1 diabetes (580 patients), the transfer from GLA-100 to GLA-300 was not accompanied by the transfer from prandial insulin and changes in the total daily dosage of insulins, or HbA1c (59.19 U/day and 59.85 U/day, and HbA1c level was 7.86 % and 7.71 %, respectively). Aft er transferring to GLA-300, the cost of one day of insulin therapy was less by 5.3 %, mainly due to the lower cost of GLA-300 compared to GLA-100 (11.7 % per unit). As for the prandial insulins, insulin aspart (37.4 %) and insulin glulisine (25.5% of prescriptions) were most oft en used. When using GLA-300 + glulisine and GLA-300 + aspart, the levels of HbA1c were similar: 7.71 ± 0.44 % and 7.64 ± 0.48 %, respectively (p60 years (73.1 %). Th e costs of using GLA-300 in this population were 5.2% lower than those when using GLA-100. In a subgroup of patients with complications who reached the target level of HbA1c (153 patients), the dosage of GLA-300 was higher by 1.58 U/day, but the costs for using GLA-300 were 7.2 % lower than those for the therapy with GLA-100. Th e costs for using basal + and basal-bolus schemes in type 2 diabetes decreased by 7.1% aft er the transfer, mainly due to the lower cost of GLA-300 with practically equal dosages of insulins before and aft er the transfer. Conclusion: Th e transfer from GLA-100 to GLA-300 in patients with both types of DM in real-life practice of prescribing these drugs does not require increased dosages, is not accompanied by any changes in HbA1c level, and reduces the direct costs on insulin therapy.
