Efficacy and Safety of Alogliptin in Elderly Patients With Type 2 Diabetes Mellitus

Abstract

Background: In Japan, with increasing age of the population, diabetic patients often become in need of hemodialysis due to diabetic nephropathy, and thus there is a demand for development of diabetic treatments that take into account renal effects in the elderly. No previous studies of alogliptin had focused on Japanese elderly subjects; we therefore assessed the effects of alogliptin in elderly individuals using available data.

Methods: Laboratory data were compiled for 1 year at intervals of 3 months following the start of alogliptin treatment. The subjects were divided into three groups by age: < 65 years (n = 110), 65 - 74 years (n = 87), and ? 75 years (n = 93). Laboratory values in comparison with baseline were compared within groups at various time points, and changes from baseline were compared among the different groups.

Results: Hemoglobin A1c (HbA1c) levels decreased significantly from baseline values in all groups at and after month 3: the change at month 12 was -0.741.45% for the age group < 65, -0.471.02% for the age group 65 - 74, and -0.421.11% for the age group ? 75. The 12-month change in estimated glomerular filtration rate (eGFR) was -6.5 12.0 for the age group < 65, -2.0 8.4 for the age group 65 - 74, and -1.5 10.0 for the age group ? 75; the reduction in the age group < 65 was significant, whereas the reduction in the age groups ? 65 was not.

Conclusions: Alogliptin significantly lowers HbA1c levels in the elderly and can be used without posing any safety issues, including renal effects, thus contributing to safe blood glucose control in clinical practice.
