Abstract
Objective: To evaluate attainment of diabetes-related quality measures with canagliflozin, a sodium glucose cotransporter 2 inhibitor, versus sitagliptin in patients with type 2 diabetes mellitus (T2DM).; Study design: This post hoc analysis included data from a 52-week, randomized, double-blind, phase 3 study comparing canagliflozin 300 mg and sitagliptin 100 mg in patients with T2DM on metformin plus sulfonylurea.; Methods: Individual and composite diabetes-related quality measures based on glycated hemoglobin (A1C), blood pressure (BP), low-density lipoprotein cholesterol (LDL-C) level, body mass index (BMI), and body weight were assessed in the overall population and a subgroup with a baseline BMI of at least 25 kg/m(2).; Results: At baseline, the proportion of patients meeting criteria for quality measures was similar between groups. At week 52, more canagliflozin-treated patients achieved quality measures of an A1C less than 8% or less than 7%, and fewer canagliflozin-treated patients had an A1C greater than 9%, compared with sitagliptin. More patients achieved BP measurement less than 140/90 mm Hg, less than 140/80 mm Hg, or less than 130/80 mm Hg with canagliflozin versus sitagliptin. The proportion of patients with an LDL-C level less than 100 mg/dL was similar between groups. More patients had a BMI of at least 25 kg/m(2) and a greater than 10 lb (4.5 kg) weight loss from baseline, and a BMI less than 30 kg/m(2) at week 52, with canagliflozin versus sitagliptin. A greater proportion of patients achieved composite end points based on A1C, BP, and LDLC level with canagliflozin versus sitagliptin. Similar results were observed in the subgroup of patients with a baseline BMI of at least 25 kg/m(2).; Conclusion: In this study involving patients with T2DM on metformin plus sulfonylurea, after 52 weeks, patients treated with canagliflozin 300 mg demonstrated better attainment of individual and composite diabetes-related quality measures compared with patients treated with sitagliptin 100 mg.
