Number of patients with available data at baseline and week 26; placebo, CANA 100 mg, and CANA 300 mg: Hispanic/Latino, 160, 199, and 198; non-Hispanic/Latino, 418, 582, and 562. d. and SBP were Rabbit Polyclonal to Sodium Channel-pan 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. Conclusions 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. strong class=”kwd-title” Keywords: Canagliflozin, Glucose Co-transporter Inhibitor, Type 2 Diabetes Mellitus, Hispanic, Latino, Efficacy, Safety Introduction Individuals of Hispanic/Latino ethnicity are at increased risk of developing type 2 diabetes mellitus (T2DM) compared with people of non-Hispanic origin.1 American Hispanics/Latinos have a 1.7-times greater risk of diabetes2 compared with non-Hispanic Whites, and face one of the highest lifetime risks to be diagnosed with diabetes, exceeding 50%.3 According to a recent survey, nearly 1 in 5 (19%) Hispanics/Latinos in the US reported that diabetes is the largest health problem facing their families,4 which accentuates the impact of diabetes in this population. The management and treatment of diabetes in the Hispanic/Latino population represents a significant health care challenge. In the United States, patients of Hispanic/Latino ethnicity have higher rates of severely elevated HbA1c, have more diabetes-related chronic complications, and are more unaware of their glycemic status compared with patients of non-Hispanic/Latino origin.5-9 The reasons for this ethnic disparity can be partially explained by a higher level of insulin resistance, which has been shown to correlate with ethnicity after adjusting for body mass index, age, and presence of T2DM.10 Insulin resistance has been reported to account for a large and significant proportion of the excess diabetes risk.11 Additionally, many Hispanic/Latino patients with T2DM are reluctant to initiate insulin therapy or increase insulin dosage in order to achieve glycemic control, mostly due to socioeconomic (eg, costs, lack of health insurance), educational (eg, lack of English language, literacy), and cultural issues.12 Differences in metabolic responses to glucose-lowering agents (eg, insulin, metformin, dipeptidyl peptidase-4 inhibitors) have been observed across racial and ethnic groups.13-15 Most currently available therapies for T2DM have an insulin-dependent mode of action. Sodium glucose co-transporter 2 (SGLT2) inhibitors are a novel class of drugs that treat T2DM through an insulin-independent mechanism.16 SGLT2 is found in the proximal renal tubules and is responsible for the majority of renal glucose reabsorption. SGLT2 inhibitors lower the renal threshold for glucose, resulting in enhanced urinary glucose excretion.17 This effect is independent of beta-cell function and insulin sensitivity.18 Therefore, the mechanism of action of SGLT2 inhibitors is complementary to that of other classes of antihyperglycemic agents (AHAs) including insulin, and may be particularly beneficial for Hispanic/Latino patients. SGLT2 inhibitors were recently included in the American Diabetes Association (ADA) Standards of Medical Care as an additional treatment option for T2DM to be used as second- or third-line therapy.19 SGLT2 inhibitors have been shown to improve glycemic control, reduce body weight (BW), and lower systolic blood pressure (SBP), with a low risk of hypoglycemia when?used alone or combined with antihyperglycemic therapies not associated with hypoglycemia.16 Our analysis evaluated the efficacy and safety of the SGLT2 inhibitor canagliflozin in Hispanic/Latino patients with T2DM, one of the larger populations with T2DM. Methods Study Design and Population A post hoc analysis was conducted using data from four randomized, double-blind, placebo-controlled phase 3 clinical studies of canagliflozin in the general T2DM patient population (ClinicalTrials.gov identifiers: “type”:”clinical-trial”,”attrs”:”text”:”NCT01081834″,”term_id”:”NCT01081834″NCT01081834, “type”:”clinical-trial”,”attrs”:”text”:”NCT01106677″,”term_id”:”NCT01106677″NCT01106677, “type”:”clinical-trial”,”attrs”:”text”:”NCT01106625″,”term_id”:”NCT01106625″NCT01106625, Tenacissoside H “type”:”clinical-trial”,”attrs”:”text”:”NCT01106690″,”term_id”:”NCT01106690″NCT01106690).20-23 All studies had a similar study design and differed mainly in their use of background AHAs. Briefly, adult patients with T2DM inadequately controlled with diet and exercise,20 metformin,21 metformin, and a sulfonylurea (SU),22 or metformin and pioglitazone,23 were included. Enrolled patients were randomly assigned to receive daily oral doses of canagliflozin 100 mg or 300 mg, or placebo (1:1:1 randomization ratio);20,22,23 or canagliflozin 100 mg or 300 mg, sitagliptin 100 mg, or placebo (2:2:2:1).21 To allow robust data comparisons, canagliflozin and placebo data from the 26-week core treatment periods of each study were included in this pooled analysis; data from patients in the high glycemic subset (HbA1c 10.0% and 12.0%) of the monotherapy study,19 which was not placebo controlled, and patients in the sitagliptin arm of the add-on to metformin study (predefined comparison.The incidence of severe hypoglycemia was low and limited to 1 patient with canagliflozin 100 mg (Hispanic/Latino cohort) and 1 patient with canagliflozin 300 mg (non-Hispanic/Latino cohort). 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.
