Acute pancreatitis risk in type 2 diabetes patients treated with canagliflozin versus other antihyperglycemic agents: an observational claims database study.

Objective: Observational evidence suggests that patients with type 2 diabetes mellitus (T2DM) are at increased risk for acute pancreatitis (AP) versus those without T2DM. A small number of AP events were reported in clinical trials of the sodium glucose co-transporter 2 inhibitor canagliflozin, though no imbalances were observed between treatment groups. This observational study evaluated risk of AP among new users of canagliflozin compared with new users of six classes of other antihyperglycemic agents (AHAs).Methods: Three US claims databases were analyzed based on a prespecified protocol approved by the European Medicines Agency. Propensity score adjustment controlled for imbalances in baseline covariates. Cox regression models estimated the hazard ratio of AP with canagliflozin compared with other AHAs using on-treatment (primary) and intent-to-treat approaches. Sensitivity analyses assessed robustness of findings.Results: Across the three databases, there were between 12,023-80,986 new users of canagliflozin; the unadjusted incidence rates of AP (per 1000 person-years) were between 1.5-2.2 for canagliflozin and 1.1-6.6 for other AHAs. The risk of AP was generally similar for new users of canagliflozin compared with new users of glucagon-like peptide-1 receptor agonists, dipeptidyl peptidase-4 inhibitors, sulfonylureas, thiazolidinediones, insulin, and other AHAs, with no consistent between-treatment differences observed across databases. Intent-to-treat and sensitivity analysis findings were qualitatively consistent with on-treatment findings.Conclusions: In this large observational study, incidence rates of AP in patients with T2DM treated with canagliflozin or other AHAs were generally similar, with no evidence suggesting that canagliflozin is associated with increased risk of AP compared with other AHAs.

Diabetic ketoacidosis in patients with type 2 diabetes treated with sodium glucose co-transporter 2 inhibitors versus other antihyperglycemic agents: An observational study of four US administrative claims databases.

PURPOSE: To compare the incidence of diabetic ketoacidosis (DKA) among patients with type 2 diabetes mellitus (T2DM) who were new users of sodium glucose co-transporter 2 inhibitors (SGLT2i) versus other classes of antihyperglycemic agents (AHAs). METHODS: Patients were identified from four large US claims databases using broad (all T2DM patients) and narrow (intended to exclude patients with type 1 diabetes or secondary diabetes misclassified as T2DM) definitions of T2DM. New users of SGLT2i and seven groups of comparator AHAs were matched (1:1) on exposure propensity scores to adjust for imbalances in baseline covariates. Cox proportional hazards regression models, conditioned on propensity score-matched pairs, were used to estimate hazard ratios (HRs) of DKA for new users of SGLT2i versus other AHAs. When I2 <40%, a combined HR across the four databases was estimated. RESULTS: Using the broad definition of T2DM, new users of SGLT2i had an increased risk of DKA versus sulfonylureas (HR [95% CI]: 1.53 [1.31-1.79]), DPP-4i (1.28 [1.11-1.47]), GLP-1 receptor agonists (1.34 [1.12-1.60]), metformin (1.31 [1.11-1.54]), and insulinotropic AHAs (1.38 [1.15-1.66]). Using the narrow definition of T2DM, new users of SGLT2i had an increased risk of DKA versus sulfonylureas (1.43 [1.01-2.01]). New users of SGLT2i had a lower risk of DKA versus insulin and a similar risk as thiazolidinediones, regardless of T2DM definition. CONCLUSIONS: Increased risk of DKA was observed for new users of SGLT2i versus several non-SGLT2i AHAs when T2DM was defined broadly. When T2DM was defined narrowly to exclude possible misclassified patients, an increased risk of DKA with SGLT2i was observed compared with sulfonylureas.

Canagliflozin and Renal Outcomes in Type 2 Diabetes and Nephropathy.

BACKGROUND: Type 2 diabetes mellitus is the leading cause of kidney failure worldwide, but few effective long-term treatments are available. In cardiovascular trials of inhibitors of sodium-glucose cotransporter 2 (SGLT2), exploratory results have suggested that such drugs may improve renal outcomes in patients with type 2 diabetes. METHODS: In this double-blind, randomized trial, we assigned patients with type 2 diabetes and albuminuric chronic kidney disease to receive canagliflozin, an oral SGLT2 inhibitor, at a dose of 100 mg daily or placebo. All the patients had an estimated glomerular filtration rate (GFR) of 30 to <90 ml per minute per 1.73 m2 of body-surface area and albuminuria (ratio of albumin [mg] to creatinine [g], >300 to 5000) and were treated with renin-angiotensin system blockade. The primary outcome was a composite of end-stage kidney disease (dialysis, transplantation, or a sustained estimated GFR of <15 ml per minute per 1.73 m2), a doubling of the serum creatinine level, or death from renal or cardiovascular causes. Prespecified secondary outcomes were tested hierarchically. RESULTS: The trial was stopped early after a planned interim analysis on the recommendation of the data and safety monitoring committee. At that time, 4401 patients had undergone randomization, with a median follow-up of 2.62 years. The relative risk of the primary outcome was 30% lower in the canagliflozin group than in the placebo group, with event rates of 43.2 and 61.2 per 1000 patient-years, respectively (hazard ratio, 0.70; 95% confidence interval [CI], 0.59 to 0.82; P = 0.00001). The relative risk of the renal-specific composite of end-stage kidney disease, a doubling of the creatinine level, or death from renal causes was lower by 34% (hazard ratio, 0.66; 95% CI, 0.53 to 0.81; P<0.001), and the relative risk of end-stage kidney disease was lower by 32% (hazard ratio, 0.68; 95% CI, 0.54 to 0.86; P = 0.002). The canagliflozin group also had a lower risk of cardiovascular death, myocardial infarction, or stroke (hazard ratio, 0.80; 95% CI, 0.67 to 0.95; P = 0.01) and hospitalization for heart failure (hazard ratio, 0.61; 95% CI, 0.47 to 0.80; P<0.001). There were no significant differences in rates of amputation or fracture. CONCLUSIONS: In patients with type 2 diabetes and kidney disease, the risk of kidney failure and cardiovascular events was lower in the canagliflozin group than in the placebo group at a median follow-up of 2.62 years.

Factors influencing longitudinal changes of circulating liver enzyme concentrations in subjects randomized to placebo in four clinical trials.

Liver enzyme concentrations are measured as safety end points in clinical trials to detect drug-related hepatotoxicity, but little is known about the epidemiology of these biomarkers in subjects without hepatic dysfunction who are enrolled in drug trials. We studied alanine and aspartate aminotransferase (ALT and AST) in subjects randomized to placebo who completed assessments over 36 mo in a cardiovascular outcome trial [the Stabilisation of Atherosclerotic Plaque by Initiation of Darapladib Therapy ("STABILITY") trial; n = 4,264; mean age: 64.2 yr] or over 12 mo in three trials that enrolled only subjects with type 2 diabetes (T2D) [the DIA trials; n = 308; mean age: 62.4 yr] to investigate time-dependent relationships and the factors that might affect ALT and AST, including body mass index (BMI), T2D, and renal function. Multivariate linear mixed models examined time-dependent relationships between liver enzyme concentrations as response variables and BMI, baseline T2D status, hemoglobin A1c levels, and renal function, as explanatory variables. At baseline, ALT was higher in individuals who were men, <65 yr old, and obese and who had glomerular filtration rate (GFR) >60 ml·min-1·1.73 m-2. ALT was not significantly associated with T2D at baseline, although it was positively associated with HbA1c. GFR had a greater impact on ALT than T2D. ALT concentrations decreased over time in subjects who lost weight but remained stable in individuals with increasing BMI. Weight change did not alter AST concentrations. We provide new insights on the influence of time, GFR, and HbA1c on ALT and AST concentrations and confirm the effect of sex, age, T2D, BMI, and BMI change in subjects receiving placebo in clinical trials. NEW & NOTEWORTHY Clinical trials provide high-quality data on liver enzyme concentrations from subjects randomized to placebo that can be used to investigate the epidemiology of these biomarkers. The adjusted models show the influence of sex, age, time, renal function, type 2 diabetes, HbA1c, and body mass index on alanine aminotransferase and aspartate aminotransferase concentrations and their relative importance. These factors need to be considered when assessing potential signals of hepatotoxicity in trials of new drugs and in clinical trials investigating subjects with nonalcoholic fatty liver disease.

Achieving the composite endpoint of HbA1c, body weight, and systolic blood pressure reduction with canagliflozin in patients with type 2 diabetes.

OBJECTIVE: In addition to achieving glycemic control, weight loss and blood pressure (BP) reduction are important components of type 2 diabetes mellitus (T2DM) management, as many patients with T2DM are overweight/obese and/or have hypertension. Canagliflozin, an SGLT2 inhibitor, has demonstrated improvements in HbA1c, body weight (BW), and systolic BP across a broad range of patients with T2DM. This analysis evaluated achievement of composite endpoints of HbA1c, BW, and systolic BP targets with canagliflozin versus placebo. METHODS: This post hoc analysis evaluated the proportion of T2DM patients achieving the composite endpoint of HbA1c reduction ≥0.5%, BW reduction ≥3%, and systolic BP reduction ≥4mmHg with canagliflozin 100 and 300mg compared with placebo using pooled data from four 26-week, phase 3 studies (N = 2313; NCT01081834, NCT01106677, NCT01106625, NCT01106690). The proportion of patients achieving the composite endpoint of HbA1c <7.0%, BW reduction ≥3%, and BP <130/80 mmHg was also evaluated. RESULTS: At week 26, greater proportions of patients met individual HbA1c, BW, and systolic BP targets with canagliflozin versus placebo. A greater proportion of patients treated with canagliflozin 100 or 300 mg versus placebo also achieved the composite endpoint of HbA1c reduction ≥0.5%, BW reduction ≥3%, and systolic BP reduction ≥4 mmHg at week 26 (21.1%, 25.3%, and 5.7%, respectively; odds ratios [95% CI] of 4.5 [3.1, 6.5] and 5.6 [3.8, 8.2]). A greater proportion of patients also achieved the composite endpoint of HbA1c <7.0%, BW reduction ≥3%, and BP <130/80 mmHg with canagliflozin 100 and 300 mg versus placebo (14.7%, 20.9%, and 3.3%, respectively; odds ratios [95% CI] of 5.2 [3.2, 8.4] and 8.4 [5.2, 13.5]). Canagliflozin was generally well tolerated, with a safety profile similar to that seen in other phase 3 studies. CONCLUSIONS: Patients with T2DM were more likely to achieve clinically important reductions in HbA1c, BW, and systolic BP with canagliflozin versus placebo.

Rationale, design and baseline characteristics of the CANagliflozin cardioVascular Assessment Study-Renal (CANVAS-R): A randomized, placebo-controlled trial.

AIMS: The primary aim of the CANagliflozin cardioVascular Assessment Study-Renal (CANVAS-R) is to determine whether the favourable effects of inhibition of the sodium glucose co-transporter 2 (SGLT2) on blood glucose, blood pressure and body weight are accompanied by protection against adverse renal outcomes. MATERIALS AND METHODS: CANVAS-R is a prospective, randomized, double-blind, placebo-controlled trial in patients with type 2 diabetes with a history or high risk of cardiovascular events. Patients were randomly assigned to once-daily placebo or canagliflozin 100 mg (with optional uptitration to 300 mg) for a planned average of 2.5 years of follow-up. The primary outcome is kidney disease progression, defined by class change in albuminuria. The two secondary outcomes are the composite of hospitalized heart failure or cardiovascular death, and cardiovascular death alone. Effects on end-stage renal disease and a range of other outcomes will also be explored. RESULTS: A total of 5812 participants were recruited at 422 sites in 24 countries between January 2014 and May 2015. The mean baseline age was 64 years, mean duration of diabetes was 14 years, mean glycated haemoglobin level was 8.3% and mean body mass index was 32 kg/m2 . Of these participants, 37% were women, 71% had a history of cardiovascular disease, 22.3% had microalbuminuria and 8.7% had macroalbuminuria. The mean baseline estimated glomerular filtration rate was 76 mL/min/1.73 m2 . The study will have at least 90% power ( P = .05) to detect a 22% or greater reduction in the risk of progression of albuminuria. CONCLUSIONS: The trial should define the potential renoprotective effect of canagliflozin and will provide additional important new data about its effects on vascular outcomes, death and kidney failure.

Longer-term safety and tolerability of canagliflozin in patients with type 2 diabetes: a pooled analysis.

OBJECTIVE: To evaluate the longer-term safety of canagliflozin, a sodium glucose co-transporter 2 (SGLT2) inhibitor, in patients with type 2 diabetes mellitus (T2DM). METHODS: The safety/tolerability of canagliflozin 100 and 300 mg were assessed using data pooled from seven placebo- and active-controlled studies of 52-104 weeks in duration that enrolled a broad range of patients with T2DM (N = 5598). Canagliflozin 100 and 300 mg as monotherapy or in combination with various background antihyperglycemic agents (AHAs) were compared with pooled non-canagliflozin treatments (i.e. placebo, sitagliptin, glimepiride). Safety was assessed based on adverse event (AE) reports, including the incidence of AEs related to the mechanism of SGLT2 inhibition. RESULTS: Overall AE incidence was similar with canagliflozin 100 and 300 mg and non-canagliflozin (73.7%, 74.5%, and 73.7%). The incidence of AE-related discontinuations and serious AEs was low and balanced across groups. The incidence of male and female genital mycotic infections, urinary tract infections, and AEs related to osmotic diuresis or volume depletion was higher with canagliflozin versus non-canagliflozin; these AEs generally occurred early with decreased incidence over time and incidence was similar across baseline HbA1c subgroups. The incidence of fractures and diabetic ketoacidosis was low and similar across groups. Canagliflozin was associated with a low incidence of hypoglycemia when used with background AHAs that are not associated with hypoglycemia; the incidence was higher among patients on background AHAs associated with hypoglycemia (i.e. insulin, sulfonylurea, glinide). LIMITATIONS: Limitations of this analysis include its post hoc nature. While this analysis included a broad population of patients, including those with a history or risk of cardiovascular disease or chronic kidney disease, the longer-term safety in these patient populations was not specifically evaluated. Ongoing outcome studies will provide data on the long-term safety of canagliflozin in these populations. CONCLUSIONS: Longer-term exposure to canagliflozin as monotherapy or in combination with other agents was generally well tolerated in patients with T2DM.

Canagliflozin Slows Progression of Renal Function Decline Independently of Glycemic Effects.

Sodium-glucose cotransporter 2 inhibition with canagliflozin decreases HbA1c, body weight, BP, and albuminuria, implying that canagliflozin confers renoprotection. We determined whether canagliflozin decreases albuminuria and reduces renal function decline independently of its glycemic effects in a secondary analysis of a clinical trial in 1450 patients with type 2 diabetes receiving metformin and randomly assigned to either once-daily canagliflozin 100 mg, canagliflozin 300 mg, or glimepiride uptitrated to 6-8 mg. End points were annual change in eGFR and albuminuria over 2 years of follow-up. Glimepiride, canagliflozin 100 mg, and canagliflozin 300 mg groups had eGFR declines of 3.3 ml/min per 1.73 m2 per year (95% confidence interval [95% CI], 2.8 to 3.8), 0.5 ml/min per 1.73 m2 per year (95% CI, 0.0 to 1.0), and 0.9 ml/min per 1.73 m2 per year (95% CI, 0.4 to 1.4), respectively (P<0.01 for each canagliflozin group versus glimepiride). In the subgroup of patients with baseline urinary albumin-to-creatinine ratio ≥30 mg/g, urinary albumin-to-creatinine ratio decreased more with canagliflozin 100 mg (31.7%; 95% CI, 8.6% to 48.9%; P=0.01) or canagliflozin 300 mg (49.3%; 95% CI, 31.9% to 62.2%; P<0.001) than with glimepiride. Patients receiving glimepiride, canagliflozin 100 mg, or canagliflozin 300 mg had reductions in HbA1c of 0.81%, 0.82%, and 0.93%, respectively, at 1 year and 0.55%, 0.65%, and 0.74%, respectively, at 2 years. In conclusion, canagliflozin 100 or 300 mg/d, compared with glimepiride, slowed the progression of renal disease over 2 years in patients with type 2 diabetes, and canagliflozin may confer renoprotective effects independently of its glycemic effects.

Canagliflozin: Efficacy and Safety in Combination with Metformin Alone or with Other Antihyperglycemic Agents in Type 2 Diabetes.

Metformin is typically the first pharmacologic treatment recommended for type 2 diabetes mellitus (T2DM), but many patients do not achieve glycemic control with metformin alone and eventually require combination therapy with other agents. Canagliflozin, a sodium glucose co-transporter 2 (SGLT2) inhibitor, was assessed in a comprehensive Phase 3 clinical development program consisting of ~10,000 participants, of which ~80% were on background therapy that consisted of metformin alone or in combination with other antihyperglycemic agents (AHAs; e.g., pioglitazone, sulfonylurea, and insulin). In addition, the efficacy and safety of canagliflozin and metformin as the initial combination therapy and canagliflozin monotherapy were assessed versus metformin in treatment-naïve patients with T2DM. Across studies in patients with T2DM who were on metformin alone or in combination with other AHAs, canagliflozin 100 and 300 mg provided improvements in glycated hemoglobin for up to 104 weeks. Canagliflozin was also associated with reductions in body weight and systolic blood pressure when added to background therapy consisting of metformin alone or with other AHAs. Canagliflozin was generally well tolerated, with increased incidence of adverse events (AEs) related to the mechanism of SGLT2 inhibition (i.e., genital mycotic infections, urinary tract infections, and osmotic diuresis-related AEs). Consistent with its insulin-independent mechanism of action, canagliflozin was associated with low rates of hypoglycemia when background therapy did not include sulfonylurea or insulin. Due to its favorable efficacy and safety profile, these results suggest that adding canagliflozin to a background regimen consisting of metformin or implementing treatment with a fixed-dose regimen of canagliflozin and metformin would provide an effective and safe treatment regimen for T2DM management.

A post-hoc analysis of the comparative efficacy of canagliflozin and glimepiride in the attainment of type 2 diabetes-related quality measures.

BACKGROUND: The randomized, double-blind CANTATA-SU (CANagliflozin Treatment And Trial Analysis Sulfonyl Urea) clinical trial compared the use of canagliflozin (100 mg or 300 mg) and maximally tolerated glimepiride (6-8 mg) over 104 weeks as add-on therapy for patients with type 2 diabetes mellitus (T2DM) inadequately controlled with metformin. Compared with glimepiride, canagliflozin use was associated with durable reductions in glycated hemoglobin (A1C), blood pressure (BP), and body weight. The aim of this post-hoc analysis of the CANTATA-SU trial was to assess the comparative efficacy of canagliflozin and glimepiride in the attainment of recently updated diabetes-related quality measures (QMs) for up to 104 weeks of treatment. METHODS: This post-hoc analysis evaluated the proportions of patients achieving individual diabetes-related QMs using data from the randomized, double-blind, Phase 3 CANTATA-SU trial. Change in A1C from baseline, and proportions of the study population achieving QMs: A1C <7.0 %, <8.0 %, and >9.0 % were assessed. Secondary endpoints included change in BP from baseline, and the proportions of the study population achieving QMs related to BP and body weight. RESULTS: The proportions of patients in the canagliflozin 100 mg, canagliflozin 300 mg, and glimepiride groups meeting criteria for all QMs were similar at baseline. At 52 and 104 weeks of treatment, canagliflozin 100 mg and canagliflozin 300 mg provided better or similar reductions in A1C from baseline and achievement of glycemic control QMs compared with glimepiride. At 52 and 104 weeks of treatment, the attainment of QMs related to reductions in body weight and BP all favored canagliflozin compared with glimepiride. Canagliflozin was associated with lower incidence of documented hypoglycemia and severe hypoglycemia compared with glimepiride. CONCLUSIONS: Using the recently adjusted and currently accepted diabetes-related QMs, this analysis observed superior glycemic control with canagliflozin compared with maximally tolerated glimepiride in patients with T2DM who were previously poorly controlled on metformin monotherapy. Compared with maximally tolerated glimepiride, canagliflozin resulted in better achievement of diabetes-related QMs related to weight loss and BP, and was associated with lower incidences of hypoglycemic events.

Efficacy and safety of canagliflozin in patients with type 2 diabetes mellitus from India.

BACKGROUND: This post hoc analysis evaluated the efficacy and safety of canagliflozin, a sodium glucose co-transporter 2 inhibitor, in patients with type 2 diabetes mellitus (T2DM) from India. METHODS: Changes from baseline in HbA1c, fasting plasma glucose (FPG), body weight, and blood pressure (BP) with canagliflozin 100 and 300 mg were evaluated in a subgroup of patients from India (n = 124) from 4 randomized, double-blind, placebo- and active-controlled, Phase 3 studies (N = 2313; Population 1). Safety was assessed based on adverse event (AE) reports in these patients and in a broader subgroup of patients from India (n = 1038) from 8 randomized, double-blind, placebo- and active-controlled, Phase 3 studies (N = 9439; Population 2). RESULTS: Reductions in HbA1c with canagliflozin 100 and 300 mg were -0.74% and -0.88%, respectively, in patients from India, and -0.81% and -1.00%, respectively, in the 4 pooled Phase 3 studies. In the Indian subgroup, both canagliflozin doses provided reductions in FPG, body weight, and BP that were consistent with findings in the overall population. The incidence of overall AEs in patients from India was generally similar with canagliflozin 100 and 300 mg and noncanagliflozin. The AE profile in patients from India was generally similar to the overall population, with higher rates of genital mycotic infections and osmotic diuresis-related and volume depletion-related AEs with canagliflozin versus noncanagliflozin. CONCLUSION: Canagliflozin provided glycemic control, body weight reduction, and was generally well tolerated in patients with T2DM from India.

Impact of Age and Estimated Glomerular Filtration Rate on the Glycemic Efficacy and Safety of Canagliflozin: A Pooled Analysis of Clinical Studies.

OBJECTIVE: Reduced efficacy has been reported in the elderly; it may be a consequence of an age-dependent decline in estimated glomerular filtration rate (eGFR) rather than ageing per se. We sought to determine the impact of these 2 parameters, as well as sex and baseline body mass index (BMI), on the efficacy and safety of canagliflozin, a sodium glucose co-transporter 2 inhibitor, in people with type 2 diabetes. METHODS: Data were pooled from 6 randomized, double-blind, placebo-controlled studies (18 or 26 weeks; N=4053). Changes in glycated hemoglobin (A1C) and systolic blood pressure (BP) from baseline with canagliflozin 100 mg and 300 mg and placebo were evaluated in subgroups by sex, baseline BMI, baseline age and baseline eGFR. Safety was assessed by reports of adverse events. RESULTS: Placebo-subtracted reductions in A1C with canagliflozin 100 mg and 300 mg were similar in men and women. A1C reductions with canagliflozin were seen across BMI subgroups and in participants aged <65 years and ≥65 years. Significantly greater placebo-subtracted reductions in A1C were seen with both canagliflozin doses in participants with higher baseline eGFR (≥90 mL/min/1.73 m(2)). Reductions in systolic BP were seen with canagliflozin across subgroups of sex, BMI, age and eGFR. A1C reductions with canagliflozin were similar for participants aged <65 or ≥65 years who had baseline eGFR ≥60 mL/min/1.73 m(2) and were smaller in older than in younger participants with baseline eGFR 45 to <60 mL/min/1.73 m(2). The overall incidence of adverse events was similar across treatment groups regardless of sex, baseline BMI, baseline age or baseline eGFR. CONCLUSIONS: Canagliflozin improved glycemic control, reduced BP and was generally well tolerated in people with type 2 diabetes across a range of ages, BMIs and renal functions.

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

OBJECTIVE: To assess the efficacy and safety of the sodium glucose co-transporter 2 (SGLT2) inhibitor canagliflozin in patients of different ethnicities. DESIGN SETTING AND PATIENTS: Post hoc analysis of data pooled from four randomized, placebo-controlled, phase 3 studies of adults with inadequately controlled type 2 diabetes mellitus (T2DM). INTERVENTIONS: Once daily oral canagliflozin 100 mg or 300 mg, or placebo. MAIN OUTCOME MEASURES: 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. RESULTS: 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/m(2), 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. 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.

Effects of canagliflozin on body weight and body composition in patients with type 2 diabetes over 104 weeks.

OBJECTIVES: Canagliflozin, a sodium glucose co-transporter 2 (SGLT2) inhibitor, has been associated with weight loss in a broad range of patients with type 2 diabetes mellitus (T2DM). This analysis further evaluated changes in body weight and composition with canagliflozin in two 104-week, Phase 3 studies. METHODS: In Study 1, patients aged 18-80 years (N = 1,450) received canagliflozin 100 or 300 mg or glimepiride as add-on to metformin for a 52-week core treatment period, followed by a 52-week extension period. In Study 2, patients aged 55-80 years (N = 714) received canagliflozin 100 or 300 mg or placebo added to stable background antihyperglycemic agents for a 26-week core treatment period, followed by a 78-week extension period. Percent change from baseline in body weight; proportion of patients with any weight loss, ≥5% weight loss, and ≥10% weight loss; change in body mass index (BMI) and waist circumference; change in body weight across weight-loss quartiles; and changes in body composition were evaluated in both studies. RESULTS: Canagliflozin 100 and 300 mg provided sustained weight loss versus either glimepiride or placebo over 104 weeks. More patients experienced any weight loss and ≥5% weight loss with canagliflozin versus comparator. Across the 3 highest weight-loss quartiles, canagliflozin provided greater weight loss versus glimepiride or placebo. BMI and waist circumference reductions were observed with canagliflozin 100 and 300 mg versus either glimepiride or placebo over 104 weeks; more patients had BMI or waist circumference reductions with canagliflozin versus comparator. Body composition analysis indicated that the majority of weight loss was due to loss of fat mass. Canagliflozin was generally well tolerated, with increased incidence of adverse events related to the SGLT2 inhibition mechanism. CONCLUSIONS: Canagliflozin 100 and 300 mg provided sustained reductions in body weight, BMI, and waist circumference in a greater proportion of patients with T2DM versus glimepiride or placebo over 104 weeks.

Efficacy and Safety of Canagliflozin in Individuals Aged 75 and Older with Type 2 Diabetes Mellitus: A Pooled Analysis.

OBJECTIVES: To compare the efficacy and safety of canagliflozin, a sodium glucose co-transporter 2 inhibitor developed to treat type 2 diabetes mellitus (T2DM), in individuals younger than 75 and those aged 75 and older. DESIGN: Randomized Phase 3 studies. SETTING: International study centers. PARTICIPANTS: Adults with T2DM. MEASUREMENTS: Changes from baseline in glycosylated hemoglobin (HbA1c ), fasting plasma glucose (FPG), blood pressure (BP), and body weight were measured. Efficacy was evaluated using pooled data from six randomized, double-blind, placebo-controlled studies (N = 4,158; n = 3,975 aged <75, n = 183 aged ≥75). Safety was assessed based on adverse event (AE) reports from eight randomized, double-blind, placebo- and active-controlled studies (N = 9,439; n = 8,949 aged <75, n = 490 aged ≥75). RESULTS: Canagliflozin 100 and 300 mg were associated with placebo-subtracted mean reductions in HbA1c in participants younger than 75 (-0.69% and -0.85%, respectively) and aged 75 and older (-0.65% and -0.55%, respectively). Dose-related reductions in FPG, body weight, and BP were seen with canagliflozin 100 and 300 mg in participants in both age groups. Overall AE incidence was 67.1% with canagliflozin 100 mg, 68.6% with canagliflozin 300 mg, and 65.9% with non-canagliflozin (pooled group of comparators in all studies) in participants younger than 75, and 72.4%, 79.1%, and 72.3%, respectively, in those aged 75 and older, with a similar safety profile in both groups. The incidence of volume depletion-related AEs was 2.2%, 3.1%, and 1.4% in participants younger than 75 with canagliflozin 100 and 300 mg and non-canagliflozin, respectively, and 4.9%, 8.7%, and 2.6%, respectively, in those aged 75 and older. CONCLUSION: Canagliflozin improved glycemic control, body weight, and BP in participants aged 75 and older. The overall incidence of AEs was high across treatment groups in participants aged 75 and older and higher than in those younger than 75. The safety profile of canagliflozin was generally similar in both age groups, with a higher incidence of AEs related to volume depletion observed with canagliflozin in participants aged 75 and older than in those younger than 75. These findings support canagliflozin, starting with the 100-mg dose, as an effective therapeutic option for older adults with T2DM.

Effects of Canagliflozin on Fracture Risk in Patients With Type 2 Diabetes Mellitus.

CONTEXT: Canagliflozin is a sodium glucose cotransporter 2 inhibitor developed to treat type 2 diabetes mellitus (T2DM). OBJECTIVE: The purpose of this study was to describe the effects of canagliflozin on bone fracture risk. DESIGN AND SETTING: This was a randomized phase 3 study in patients with T2DM. PATIENTS AND INTERVENTIONS: Canagliflozin doses of 100 and 300 mg were evaluated in the overall population of patients from 9 placebo- and active-controlled studies (N = 10 194), as well as in separate analyses of a single trial enriched with patients with a prior history/risk of cardiovascular disease (ie, the CANagliflozin cardioVascular Assessment Study [CANVAS]; N = 4327) and a pooled population of 8 non-CANVAS studies (N = 5867). OUTCOME MEASURES: The incidence of adjudicated fracture adverse events (AEs), fall-related AEs, and volume depletion-related AEs was assessed. RESULTS: The incidence of fractures was similar with canagliflozin (1.7%) and noncanagliflozin (1.5%) in the pooled non-CANVAS studies. In CANVAS, a significant increase in fractures was seen with canagliflozin (4.0%) vs placebo (2.6%) that was balanced between the upper and lower limbs. The incidence of fractures was higher with canagliflozin (2.7%) vs noncanagliflozin (1.9%) in the overall population, which was driven by the increase of fractures in CANVAS. The incidence of reported fall-related AEs was low, but significantly higher with canagliflozin in CANVAS, potentially related to volume depletion-related AEs, but not significantly different in the pooled non-CANVAS studies and the overall population. CONCLUSIONS: Fracture risk was increased with canagliflozin treatment, driven by CANVAS patients, who were older, with a prior history/risk of cardiovascular disease, and with lower baseline estimated glomerular filtration rate and higher baseline diuretic use. The increase in fractures may be mediated by falls; however, the cause of increased fracture risk with canagliflozin is unknown.

Renal effects of canagliflozin in type 2 diabetes mellitus.

BACKGROUND: Chronic kidney disease is commonly associated with type 2 diabetes mellitus (T2DM) and may impact the efficacy and safety of glucose-lowering therapies. Canagliflozin, a sodium glucose co-transporter 2 inhibitor, reduces blood glucose levels in patients with T2DM by lowering the renal threshold for glucose, thereby promoting urinary glucose excretion. This review describes the pharmacology, efficacy and safety of canagliflozin according to kidney function in participants with T2DM. METHODS: Published articles that reported efficacy, safety and pharmacokinetics/pharmacodynamics data for canagliflozin in patients with T2DM and impaired renal function, and renal safety data with canagliflozin in various populations of patients with T2DM through May 2015 were included. RESULTS: Early transient reductions in estimated glomerular filtration rate were observed with canagliflozin; these changes generally stabilized or attenuated over time and reversed after discontinuation, suggesting no renal (glomerular or tubular) damage with canagliflozin treatment. Urinary albumin-to-creatinine ratios were reduced with canagliflozin. Canagliflozin was generally well tolerated in patients with normal or mild to moderately impaired renal function, with a modestly higher incidence of renal-related adverse events and volume depletion-related adverse events in patients with moderate renal impairment. Adverse events related to potassium elevations were infrequent with canagliflozin 100 mg regardless of kidney function status; however, patients with moderately impaired kidney function experienced hyperkalemia more frequently with canagliflozin 300 mg compared with patients treated with either canagliflozin 100 mg or placebo. Canagliflozin was not associated with increased cardiovascular risk across studies; however, relatively few events among patients with impaired renal function meant that the analysis was not adequately powered to examine this outcome, and results from separate trials are awaited. CONCLUSIONS: Overall, canagliflozin is associated with small, transient changes in kidney function, and is well tolerated in patients with T2DM with varying kidney function status.

Achievement of treatment goals with canagliflozin in patients with type 2 diabetes mellitus: a pooled analysis of randomized controlled trials.

OBJECTIVE: To evaluate attainment of diabetes-related treatment goals with canagliflozin, a sodium glucose co-transporter 2 inhibitor, versus placebo in patients with type 2 diabetes mellitus (T2DM). RESEARCH DESIGN AND METHODS: Data were pooled from four 26-week, placebo-controlled, Phase 3 studies of patients with T2DM (N = 2313). Goal attainment with canagliflozin 100 and 300 mg versus placebo was evaluated in the overall population, and in subgroups based on age and sex, at baseline and Week 26. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov NCT01081834, NCT01106677, NCT01106625, NCT01106690. MAIN OUTCOME MEASURES: Proportion of patients achieving hemoglobin A1C (A1C) < 7.0% and ≤ 6.5%, systolic blood pressure (SBP) < 140 and < 130 mmHg, diastolic blood pressure (DBP) < 90 and < 80 mmHg, low-density lipoprotein cholesterol (LDL-C) < 100 mg/dL (2.6 mmol/L), high-density lipoprotein cholesterol (HDL-C) ≥ 40 mg/dL (1.0 mmol/L), and the composite endpoint of A1C < 7.0%, BP < 130/80 mmHg, and LDL-C <100 mg/dL (2.6 mmol/L) at baseline and Week 26, and proportion with body weight reduction ≥ 5% at Week 26. RESULTS: At baseline, similar proportions of patients met diabetes-related treatment goals across groups. At Week 26, a greater proportion of patients achieved A1C, SBP, DBP, and HDL-C goals with canagliflozin 100 and 300 mg compared with placebo. More patients achieved body weight reduction of ≥ 5% with canagliflozin 100 and 300 mg versus placebo at Week 26. Fewer patients had LDL-C < 100 mg/dL (2.6 mmol/L) at Week 26 with canagliflozin 100 and 300 mg versus placebo. Canagliflozin 100 and 300 mg also provided better attainment of the composite endpoint of A1C <7.0%, BP < 130/80 mmHg, and LDL-C < 100 mg/dL (2.6 mmol/L) compared with placebo. Attainment of diabetes-related treatment goals was generally similar regardless of age and sex. Key limitations of this analysis include the selection of specific treatment targets that may not be reflective of all patient experiences, the non-prespecified, post hoc nature of the analysis, and the short duration of studies included in the pooled population. CONCLUSION: Canagliflozin was associated with better attainment of diabetes-related treatment goals compared with placebo, and was generally well tolerated at 26 weeks.

Canagliflozin: a sodium glucose co-transporter 2 inhibitor for the treatment of type 2 diabetes mellitus.

The sodium glucose co-transporter 2 (SGLT2) inhibitor canagliflozin is a novel treatment option for adults with type 2 diabetes mellitus (T2DM). In patients with hyperglycemia, SGLT2 inhibition lowers plasma glucose levels by reducing the renal threshold for glucose (RTG ) and increasing urinary glucose excretion (UGE). Increased UGE is also associated with a mild osmotic diuresis and net caloric loss, which can lead to reductions in body weight and blood pressure (BP). After promising results from preclinical and phase I/II studies, the efficacy and safety of canagliflozin was evaluated in a comprehensive phase III development program in over 10,000 patients with T2DM on various background therapies. Canagliflozin improved glycemic control and provided reductions in body weight and BP versus placebo and active comparators in studies of up to 2 years' duration. Canagliflozin was generally well tolerated, with higher incidences of adverse events (AEs) related to the mechanism of action, including genital mycotic infections and AEs related to osmotic diuresis. Results from the preclinical and clinical studies led canagliflozin to be the first-in-class SGLT2 inhibitor approved in the United States, and support canagliflozin as a safe and effective therapeutic option across a broad range of patients with T2DM.
