Real-world Clinical Outcomes Among Patients With Type 2 Diabetes Receiving Canagliflozin at a Specialty Diabetes Clinic: Subgroup Analysis by Baseline HbA 1c and Age.

PURPOSE: Canagliflozin, a sodium glucose co-transporter 2 inhibitor developed for the treatment of type 2 diabetes mellitus (T2DM), has demonstrated effectiveness in patients with T2DM receiving care at a specialty diabetes clinic. We report the outcomes in these patients in subgroups classified by baseline hemoglobin A1c (HbA1c ) and age.

METHODS: This subgroup analysis was based on a review of data from the electronic health records of adults with T2DM who were prescribed canagliflozin at a specialty diabetes clinic and who returned for ≥1 follow-up office visit. Mean changes from baseline to the first and second follow-up office visits in HbA1c , body weight, and systolic and diastolic blood pressure (BP) were calculated in each subgroup classified by baseline HbA1c (≥7.0%, ≥8.0%, and >9.0%) and age (<65 and ≥65 years).

FINDINGS: Of the 462 patients included in the study, 430, 305, and 169 patients had baseline HbA1c ≥7.0%, ≥8.0%, and >9.0%, respectively; 396 and 66 patients were aged <65 and ≥65 years, respectively. With canagliflozin use, patients across subgroups classified by baseline HbA1c and age experienced clinically and statistically significant reductions from baseline in HbA1c , body weight, and systolic BP that were sustained over 2 office visits; diastolic BP was also reduced across baseline HbA1c and age subgroups. Greater reductions in HbA1c were seen among the canagliflozin-treated patients with higher baseline HbA1c and among younger versus older patients.

IMPLICATION: These findings from clinical practice demonstrate real-world effectiveness of canagliflozin in lowering HbA1c , body weight, and systolic BP among patients with T2DM, regardless of baseline HbA1c levels or age.
