Efficacy and safety of ertugliflozin across racial groups in patients with type 2 diabetes mellitus.

Objective: To assess the efficacy and safety of the sodium-glucose cotransporter 2 inhibitor ertugliflozin across racial groups in patients with type 2 diabetes mellitus (T2DM). Methods: Pooled analysis of data from randomized, double-blind studies in the ertugliflozin phase III development program. Seven placebo- and comparator-controlled studies were used to assess safety (N = 4859) and three placebo-controlled studies were used to assess efficacy (N = 1544). Least-squares (LS) mean change from baseline was calculated for glycated hemoglobin (HbA1c), body weight and systolic blood pressure (SBP). Safety evaluation included overall and prespecified adverse events (AEs). Results: At Week 26, ertugliflozin provided a greater reduction in HbA1c, body weight and SBP versus placebo in all racial subgroups. The placebo-adjusted LS mean change (95% confidence interval) from baseline in HbA1c was -0.8% (-1.0, -0.7) and -1.0% (-1.1, -0.8) with ertugliflozin 5 mg and 15 mg, respectively, in the White subgroup, -0.7% (-1.2, -0.2) and -0.8% (-1.3, -0.3) in the Black subgroup, and -0.8% (-1.1, -0.5) and -1.0% (-1.3, -0.8) in the Asian subgroup. The incidences of overall AEs, serious AEs and AEs leading to discontinuation from study medication were similar between the ertugliflozin 5 mg, 15 mg and non-ertugliflozin groups within each racial subgroup. The incidence of female genital mycotic infection (GMI) was higher with ertugliflozin than non-ertugliflozin across all racial subgroups. The incidence of male GMI was higher with ertugliflozin than non-ertugliflozin in the White sub-group; however, there were few male GMI events in the non-White subgroups. Conclusions: In patients with T2DM, treatment with ertugliflozin improved HbA1c, body weight and SBP across all racial subgroups. Ertugliflozin had a generally similar safety profile across racial subgroups and was generally well tolerated.
