Efficacy and Safety of Canagliflozin in Patients With Type 2 Diabetes Mellitus of Different Ethnicity

<p><strong>Objective</strong>: To assess the efficacy and safety of the sodium glucose co-transporter 2 (SGLT2) inhibitor canagliflozin in patients of different ethnicities.</p><p><strong>Design, Setting, and Patients:</strong> Post hoc analysis of data pooled from four randomized, placebo-controlled, phase 3 studies of adults with inadequately controlled type 2 diabetes mellitus (T2DM).</p><p><strong>Interventions:</strong> Once daily oral canagliflozin 100 mg or 300 mg, or placebo.</p><p><strong>Main Outcome Measures:</strong> Efficacy endpoints included change from baseline in HbA1c, body weight (BW), systolic blood pressure (SBP), and lipids at week 26; safety and tolerability were assessed by adverse event reports.</p><p><strong>Results:</strong> Of the 2,313 patients included in this pooled analysis, 609 self-identified as Hispanic/Latino. Hispanic/Latino patients had a mean age of 54 years, mean duration of T2DM of 7 years, mean HbA1c of 8.1%, mean body mass index of 31.2 kg/m2, and mean SBP of 126.1 mm Hg. There were more women in the non-Hispanic/Latino cohort (63%) compared with the Hispanic/ Latino cohort. Placebo-subtracted changes in HbA1c were −.82% with canagliflozin 100 mg and −.94% with canagliflozin 300 mg in the Hispanic/Latino cohort, which were similar to reductions observed in the non-Hispanic/Latino cohort. Significantly greater dose-related reductions in HbA1c, BW, and SBP were observed with both canagliflozin doses compared with placebo. Canagliflozin was generally well-tolerated. Genital mycotic infections were less frequent in Hispanic/Latino women than in non-Hispanic/Latino women.</p><p><strong>Conclusions:</strong> The SGLT2 inhibitor canagliflozin was generally well-tolerated and was associated with clinically meaningful reductions in HbA1c, BW, and SBP in both Hispanic/Latino and non-Hispanic/ Latino patients with T2DM. <em>Ethn Dis.</em> 2016;26(1):221-228; doi:10.18865/ ed.26.2.221</p>
