Ethnic disparities in cardiovascular and renal responses to canagliflozin between Asian and White patients with type 2 diabetes mellitus: A post hoc analysis of the CANVAS Program. Diabetes Obes Metab 2024; 26:878-890. [PMID: 38031821 DOI: 10.1111/dom.15380] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 10/17/2023] [Accepted: 10/25/2023] [Indexed: 12/01/2023]
Abstract
AIM To assess the potential heterogeneity in cardiovascular (CV), renal and safety outcomes of canagliflozin between Whites and Asians, as well as these outcomes in each subgroup. MATERIALS AND METHODS The CANVAS Program enrolled 10 142 patients with type 2 diabetes, comprising 78.34% Whites and 12.66% Asians. CV, renal and safety outcomes were comprehensively analysed using Cox regression models, while intermediate markers were assessed using time-varying mixed-effects models. Racial heterogeneity was evaluated by adding a treatment-race interacion term. RESULTS Canagliflozin showed no significant racial disparities in the majority of the CV, renal and safety outcomes. The heterogeneity (p = .04) was observed on all-cause mortality, with reduced risk in Whites (hazard ratio 0.84; 95% confidence interval 0.71-0.99) and a statistically non-significant increased risk in Asians (hazard ratio 1.64; 95% confidence interval 0.94-2.90). There was a significant racial difference in acute kidney injury (p = .04) and a marginally significant racial heterogeneity for the composite of hospitalization for heart failure and CV death (p = .06) and serious renal-related adverse events (p = .07). CONCLUSION Canagliflozin reduced CV and renal risks similarly in Whites and Asians; however, there was a significant racial discrepancy in all-cause mortality. This distinction may be attributed to the fact that Asian patients exhibited diminished CV protection effects and more renal adverse events with canagliflozin, potentially resulting from the smaller reductions in weight and uric acid. These findings highlight the importance of investigating the impact of race on treatment response to sodium-glucose cotransporter-2 inhibitors and provide more precise treatment strategies.

Abstract
BACKGROUND AND AIMS Scar tissue accumulation in organs is the underlying cause of many fibrotic diseases. Due to the extensive array of organs affected, the long-term nature of fibrotic processes and the large number of people who suffer from the negative impact of these diseases, they constitute a serious health problem for modern medicine and a huge economic burden on society. Sodium-glucose cotransporter-2 inhibitors (SGLT2is) are a relatively new class of anti-diabetic pharmaceuticals that offer additional benefits over and above their glucose-lowering properties; these medications modulate a variety of diseases, including fibrosis. Herein, we have collated and analyzed all available research on SGLT2is and their effects on organ fibrosis, together with providing a proposed explanation as to the underlying mechanisms. METHODS PubMed, ScienceDirect, Google Scholar and Scopus were searched spanning the period from 2012 until April 2023 to find relevant articles describing the antifibrotic effects of SGLT2is. RESULTS The majority of reports have shown that SGLT2is are protective against lung, liver, heart and kidney fibrosis as well as arterial stiffness. According to the results of clinical trials and animal studies, many SGLT2 inhibitors are promising candidates for the treatment of fibrosis. Recent studies have demonstrated that SGLT2is affect an array of cellular processes, including hypoxia, inflammation, oxidative stress, the renin-angiotensin system and metabolic activities, all of which have been linked to fibrosis. CONCLUSION Extensive evidence indicates that SGLT2is are promising treatments for fibrosis, demonstrating protective effects in various organs and influencing key cellular processes linked to fibrosis.

Abstract
In the treatment of type 2 diabetes mellitus (T2DM), comprehensive management of multiple risk factors, such as blood glucose, body weight, and lipids, is important to prevent disease progression. Although the combination of dipeptidyl peptidase-4 (DPP-4) inhibitor and sodium-glucose co-transporter 2 (SGLT2) inhibitor is often used clinically, the effects of this combination, other than glucose metabolism, have yet to be thoroughly investigated. In this study, we evaluated the effects of combined treatment with a DPP-4 inhibitor, teneligliptin, and an SGLT2 inhibitor, canagliflozin, on the body weight and lipid metabolism in high-fat diet (HFD)-induced obese mice. We found that monotherapy with teneligliptin or canagliflozin showed suppressive effects on high-fat diet-induced body weight gain and reduced inguinal white adipose tissue (iWAT) mass, and combined treatment additively reduced body weight gain and iWAT mass. Teneligliptin significantly increased oxygen consumption during the light phase, and this effect was preserved in the combined treatment. The combined treatment did not alter the mRNA expression levels of thermogenesis-related genes in adipose tissue but showed the tendency to additively induce mRNA of fatty acid oxidation-related genes in brown adipose tissue and tended to additively decrease mRNA of fatty acid synthesis-related genes in iWAT and liver tissues. These results suggest that combined treatment with teneligliptin and canagliflozin additively suppresses HFD-induced body weight gain with increasing oxygen consumption and modulating the expression of lipid metabolism-related genes. This combination therapy may provide effective body weight management for patients with T2DM and obesity.

Abstract
The prevalence of type 2 diabetes mellitus continues to increase in many Asian countries, with possible contributing factors, such as younger-onset disease, diabetes development at lower body mass index, higher visceral fat accumulation and poorer β-cell function, among Asian populations. Sodium-glucose cotransporter 2 inhibitors have been shown to confer favorable effects in type 2 diabetes mellitus patients, such as improved glycemic control, weight and blood pressure reduction, and importantly, cardiorenal benefits. Sodium-glucose cotransporter 2 inhibitors are generally well-tolerated, and have a well-defined safety profile based on evidence from numerous clinical trials and post-marketing pharmacovigilance reporting. To our knowledge, this review is the first to provide a comprehensive coverage of the adverse events of sodium-glucose cotransporter 2 inhibitors, as well as their management and counseling aspects for Asian type 2 diabetes mellitus populations.

Real-World Evidence of Treatment with Teneligliptin/Canagliflozin Combination Tablets for Type 2 Diabetes Mellitus: A Post-Marketing Surveillance in Japan. Adv Ther 2022; 39:1642-1658. [PMID: 35138572 PMCID: PMC8989929 DOI: 10.1007/s12325-021-02038-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Accepted: 12/23/2021] [Indexed: 11/21/2022]
Abstract
Introduction Teneligliptin/canagliflozin combination tablets, which combine a dipeptidyl peptidase-4 (DPP-4) inhibitor (teneligliptin) and a sodium-glucose cotransporter 2 (SGLT2) inhibitor (canagliflozin), are a treatment option for type 2 diabetes mellitus (T2DM) in Japan. This post-marketing surveillance evaluated the real-world safety and effectiveness of teneligliptin/canagliflozin combination tablets, and changes in self-reported adherence to oral antihyperglycaemic agents. Methods Japanese patients with T2DM who were prescribed the combination tablets for the first time between December 2017 and June 2018 were registered and followed up for 12 months. Safety and effectiveness were assessed in terms of adverse drug reactions (ADRs) and the changes in haemoglobin A1c (HbA1c) and body weight from baseline to 12 months with the last observation carried forward, respectively. Adherence was assessed using the Morisky Medication Adherence Scale 8. Results Overall, 821 patients were eligible for the analyses, including 733 who were prescribed the combination tablets for 12 months. ADRs and serious ADRs were reported in 4.38% and 0.85% of patients, respectively. Gastrointestinal disorders (0.97%) were the most common class of ADRs. No new safety concerns were identified beyond those described in the Japanese package insert. The changes in HbA1c and body weight from baseline to 12 months were − 0.43 ± 0.93% and − 1.29 ± 5.57 kg, respectively. The reductions in HbA1c at 12 months tended to be greater among patients who switched from either DPP-4 inhibitors (− 0.71 ± 0.89%) or SGLT2 inhibitors (− 0.51 ± 1.00%) relative to patients who switched from both (− 0.22 ± 0.88%). The decrease in body weight was greatest among patients who switched from DPP-4 inhibitors. An improvement in self-reported adherence to oral antihyperglycaemic agents occurred after switching to the combination tablets. Conclusion Teneligliptin/canagliflozin combination tablets were effective and associated with an improvement in adherence without new safety concerns in Japanese patients with T2DM in real-world clinical practice. Trial Registration JapicCTI-173778. Supplementary Information The online version contains supplementary material available at 10.1007/s12325-021-02038-5. Teneligliptin/canagliflozin combination tablets are used as an option for the treatment of type 2 diabetes mellitus in Japan. We performed this surveillance to obtain data on the frequency of side effects (adverse drug reactions) and effectiveness (in terms of changes in haemoglobin A1c and body weight) in Japanese patients treated with teneligliptin/canagliflozin combination tablets in real-world clinical practice. We also asked patients to evaluate their adherence to oral antihyperglycaemic agents as part of their prescribed therapies. We collected data for up to 12 months. We detected no new safety concerns, other than those already described in the Japanese package insert for the combination tablets. In terms of effectiveness, we observed improvements in both haemoglobin A1c and body weight over 12 months of treatment. Furthermore, self-reported adherence to oral antihyperglycaemic agents improved after treatment with the combination tablets.

Abstract
INTRODUCTION This long-term post-marketing surveillance (SAPPHIRE) collected information on the safety and effectiveness of canagliflozin (approved dose 100 mg) prescribed to patients with type 2 diabetes mellitus (T2DM) in real-world practice in Japan. METHODS Patients with T2DM who were prescribed canagliflozin between December 2014 and September 2016 were registered and observed for up to 3 years. Safety was evaluated in terms of adverse drug reactions (ADRs). Effectiveness was assessed in terms of glycaemic control. Data were also analysed across age subgroups (< 65, ≥ 65 to < 75, and ≥ 75 years old) and the estimated glomerular filtration rate (eGFR) categories for chronic kidney disease (G1-G5 based on eGFR) at baseline. RESULTS A total of 12,227 patients were included in the safety analyses and 11,675 in effectiveness analyses. Overall, 7104 patients were treated with canagliflozin for ≥ 3 years. The mean age, haemoglobin A1c (HbA1c), and eGFR at baseline were 58.4 ± 12.5 years, 8.01 ± 1.49%, and 80.04 ± 21.85 mL/min/1.73 m2, respectively. There were 1836 ADRs in 1312 patients (10.73%) and 268 serious ADRs in 225 patients (1.84%). The most common ADRs were those related to volume depletion (1.39%), genital infection (1.34%), polyuria/pollakiuria (1.23%), and urinary tract infection (1.19%). The frequencies of ADRs tended to increase with age and stage of chronic kidney disease. The reductions in mean HbA1c after starting canagliflozin were maintained for up to 3 years with a mean change of - 0.68% (n = 6345 at 3 years). Maintained reductions in mean HbA1c were observed in each age subgroup and in patients with G1-G3b renal function. CONCLUSION This surveillance in real-world clinical practice showed that canagliflozin provides sustained glucose-lowering effects in patients with T2DM, including elderly patients and patients with moderate renal impairment, without new safety concerns beyond those already described in the Japanese package insert.

Diabetes Metab Syndr Obes 2020; 13:2765-2779. [PMID: 32821142 PMCID: PMC7417649 DOI: 10.2147/dmso.s193528] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/17/2020] [Accepted: 07/08/2020] [Indexed: 12/13/2022] Open
Abstract
Metformin remains the first pharmacological choice for treating hyperglycemia in type 2 diabetes (T2DM) in most international guidelines. Sodium-glucose cotransporter type 2 inhibitors (SGLT2is) are increasingly used as add-on therapy. T2DM pathophysiology is different in Asian and non-Asian (mainly Caucasian) patients. The aim of this systematic review is to compare the efficacy of SGLT2is vs placebo added to metformin in randomized controlled trials (RCTs: range 12-52 weeks) in Asian versus non-Asian patients with T2DM. The primary endpoint is the reduction in glycated hemoglobin (HbA1c) from baseline and key secondary endpoints are reductions in fasting plasma glucose (FPG), body weight (BW) and systolic blood pressure (SBP). Systematic literature search collected 7 RCTs (3 with 2 doses) in Asian patients (10 analyses, n=1164, iSGLT2: canagliflozin, dapagliflozin, ertugliflozin, ipragliflozin, tofogliflozin)) and 10 RCTs (6 with two doses) in non-Asian patients (16 analyses, n=2482, iSGLT2: canagliflozin, dapagliflozin, empagliflozin, ertugliflozin, ipragliflozin). Baseline values of HbA1c (7.98±0.19 vs 7.89±0.27%), FPG (8.80 ±0.46 vs 9.11±0.49 mmol/l) and SBP (128.4±1.6 vs 130.2±3.1 mmHg) were not significantly different in Asian vs non-Asian patients, but BW was lower in Asian patients (71.6±4.8 vs 88.0±2.5 kg, p<0.001). The placebo-adjusted weighed mean differences (WMD, 95% CI) were similar in Asian versus non-Asian patients regarding the reductions in HbA1c -0.60 (-0.68, -0.53) % versus -0.54 (-0.59, -0.49) % (p=0.568), FPG -1.37 (-1.53, -1.22) mmol/l vs -1.37 (-1.47, -1.27) mmol/l (p=0.627), BW when expressed in percentage of baseline BW -2.23 (-2.55, -1.90) % vs -2.16 (-2.37, -1.96) % (p=0.324), and SBP -4.53 (-5.53, -3.53) mmHg vs -4.06 (-4.83, -3.29) mmHg) (p=0.223). In conclusion, clinical efficacy of SGLT2i, as an add-on treatment to metformin monotherapy in patients with T2DM, is similar in Asian versus non-Asian patients, despite known ethnic differences in phenotype and pathophysiology of T2DM.

Abstract
Background: Sodium/glucose cotransporter-2 (SGLT2) inhibitors improve glycemic control and reduce body weight by increasing glycosuria. Although a compensatory increase of food intake has been reported, the long-term effect of SGLT2 inhibitors on food intake remains unclear. This study investigated the influence of canagliflozin on calorie and nutrient intake over 1 year. Materials and Methods: Patients with type 2 diabetes (n = 107) were enrolled and followed prospectively while receiving canagliflozin at 100 mg/day for 12 months. Intake of nutrients was investigated by using the food frequency questionnaire. Hemoglobin A1c, body weight, and satisfaction with diabetes treatment (assessed by the Diabetes Treatment Satisfaction Questionnaire: DTSQ) were also investigated. Results: The baseline total energy intake was 1723 ± 525 kcal/day and it showed a persistent increase during treatment with canagliflozin, being 132 kcal higher at 6 months (P = 0.0058) and 113 kcal higher at 12 months (P = 0.0516). Intake of all three macronutrients (carbohydrate, protein, and fat) was significantly increased after 6 months of canagliflozin treatment (P = 0.0129, P = 0.0160, and P = 0.0314, respectively), but their ratio was unchanged. The DTSQ score improved significantly and both hemoglobin A1c and body weight showed a significant decrease throughout treatment (all P < 0.0001). Conclusions: After patients with type 2 diabetes commenced canagliflozin, their calorie intake increased without changing the ratio of the three macronutrients. Despite elevation of the calorie intake, glycemic control improved and weight loss was achieved. Satisfaction with treatment of diabetes also increased.

Abstract
PURPOSE Sodium-glucose co-transporter-2 (SGLT2) inhibitors have various pleiotropic effects, including body weight reduction, and therefore have the potential to be used in various applications. However, such effects have not been fully investigated; thus, non-clinical studies using animal models are needed. In animal experiments, SGLT2 inhibitors are usually administered by oral or dietary methods. However, the detailed characteristics of these dosing methods, especially to induce their pleiotropic effects, have not been reported. Therefore, we compared the preventive effects of canagliflozin, an SGLT2 inhibitor, on body weight gain following oral gavage and dietary administration methods in a mouse model of diet-induced obesity. METHODS Canagliflozin was dosed by oral gavage or dietary administration for 9 weeks to 6-week-old C57BL/6N mice fed a high-fat diet, and parameters related to obesity were evaluated. RESULTS The suppression of body weight gain, fat mass, and hepatic lipid content was observed following both dosing methods, whereas the effect on body weight tended to be stronger in the dietary administration group. In adipose tissue, fatty acid synthase expression was significantly decreased in the dietary administration group, and its expression was significantly correlated with fat mass. However, the expression of genes related to fatty acid oxidation was unchanged, indicating that the preventive effect on body weight gain was mediated mainly through the suppression of lipid synthesis rather than the promotion of lipid oxidation. CONCLUSION Canagliflozin prevented body weight gain through the suppression of lipid synthesis via both dosing methods, although there were some differences in the efficacy. The findings of our study can help to identify new mechanisms of action of SGLT2 inhibitors and potential applications.

Investigation of the Effect of Canagliflozin on the Disposition Index, a Marker of Pancreatic Beta Cell Function, in Patients with Type 2 Diabetes. Diabetes Metab Syndr Obes 2020; 13:4457-4468. [PMID: 33244248 PMCID: PMC7683829 DOI: 10.2147/dmso.s273396] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Accepted: 09/25/2020] [Indexed: 11/29/2022] Open
Abstract
AIM Our aim was to investigate the effects of add-on canagliflozin with glimepiride dose adjustment or glimepiride dose adjustment on pancreatic beta cell function in patients with type 2 diabetes mellitus and inadequate glycemic control despite stable triple therapy (metformin, teneligliptin, and glimepiride) plus diet/exercise therapy. METHODS Forty patients on stable triple therapy were randomized to glimepiride dose adjustment without (glimepiride group) or with add-on canagliflozin 100 mg (canagliflozin group) for 24 weeks. The glimepiride dose was adjusted every 4 weeks based on continuous glucose monitoring over the previous 2 weeks according to a prespecified algorithm. After the 24-week treatment period, the patients returned to the pre-intervention regimen for 1 week (wash-out period). Patients underwent 75 g OGTTs at the start of the run-in period and at the end of the wash-out period. The primary endpoint was the change in disposition index (DI). RESULTS Thirty-nine patients completed the study (canagliflozin, n = 19; glimepiride, n = 20). The change in DI was +5.1% and -11.0% in the canagliflozin and glimepiride groups, respectively, with a between-group difference ratio of 18.0% (P = 0.330). HbA1c, fasting plasma glucose, body weight, and daily-life continuous glucose monitoring-derived parameters improved in the canagliflozin group. Hypoglycemia occurred in 60% (44 episodes) and 70% (79 episodes) of patients in the canagliflozin and glimepiride groups, respectively. The change in DI was significantly correlated with the changes in glycemic control and variability in overall cohort. CONCLUSION Adding canagliflozin to the triple therapy improved beta cell function by 18%, but it did not reach statistical significance. This study also demonstrated a correlation between the change in DI and glycemic control. As canagliflozin improved both glucose level and variability with relatively lower risk of hypoglycemia compared with glimepiride dose adjustment, adding canagliflozin to the triple therapy may be clinically beneficial. TRIAL REGISTRATION UMIN000030208/jRCTs051180036.

Abstract
Teneligliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor that was approved for the treatment of type 2 diabetes mellitus (T2DM) in Japan and Korea and is being researched in several countries. Teneligliptin is a potent, selective, and long-lasting DPP-4 inhibitor with a t½ of approximately 24 h and unique pharmacokinetic properties: it is metabolized by cytochrome P450 (CYP) 3A4 and flavin-containing monooxygenase 3 (FMO3), or excreted from the kidney in an unchanged form. Because of its multiple elimination pathways, dose adjustment is not needed in patients with hepatic or renal impairment, and it is considered to have a low potential for drug–drug interactions. Clinical studies and postmarketing surveillance show that teneligliptin, administered as monotherapy and/or in combination with antihyperglycemic agents, is effective and well tolerated in T2DM patients, including in elderly patients and those with renal impairment. Furthermore, teneligliptin has antioxidative properties, which induce the antioxidant cascade, as well as ·OH scavenging properties. In addition, it has shown endothelial protective effects in several non-clinical and clinical studies. From its unique profile and clinical data, teneligliptin represents a potential therapeutic option in a wide variety of patients, including elderly diabetic patients and those with renal impairment. The fixed-dose combination (FDC) tablet of teneligliptin and canagliflozin has been approved in Japan; this is the first FDC tablet of a DPP-4 inhibitor and sodium glucose co-transporter 2 inhibitor in Japan, and the third globally. The FDC tablet may also provide additional prescribing and adherence benefits.

Abstract
AIMS/INTRODUCTION Specified Drug Use Results Survey of Ipragliflozin Treatment in Type 2 Diabetic Patients: Long-term Use is an ongoing postmarketing study of ipragliflozin for long-term use in Japanese patients with type 2 diabetes mellitus. A subgroup analysis of data from the study was carried out to investigate the impact of obesity on the efficacy and safety of ipragliflozin in this population. MATERIALS AND METHODS Patients were divided into the following subgroups according to their body mass index (BMI): <22.0, 22.0 to <25.0, 25.0 to <30.0 and ≥30.0 kg/m2 . Changes in bodyweight and glycemic parameters up to 3 months were evaluated, as well as adverse drug reactions (ADRs) that occurred during ipragliflozin treatment. RESULTS In the efficacy analysis set (8,633 patients), glycemic control and bodyweight statistically significantly improved from baseline to 3 months in all BMI subgroups (all P < 0.05). No strong correlations were identified between changes in bodyweight and changes in hemoglobin A1c, waist circumference or BMI in any of the subgroups. The incidence of adverse drug reactions was 6.29, 8.44, 11.18 and 11.74% in the <22.0, 22.0 to <25.0, 25.0 to <30.0 and ≥30.0 kg/m2 groups, respectively (P = 0.001), in the safety analysis set (n = 11,053 patients). CONCLUSIONS In Japanese patients with type 2 diabetes mellitus, ipragliflozin improved glycemic control and reduced bodyweight, regardless of BMI. Adverse drug reactions were more common in patients with higher BMI than in those with lower BMI.

Abstract
PURPOSE Agents that inhibit sodium glucose co-transporter 2 (SGLT2), including canagliflozin and dapagliflozin, become available for the treatment of Chinese patients with type 2 diabetes mellitus (T2DM). This study assessed the economic outcomes of canagliflozin 100 mg versus dapagliflozin 10 mg in patients with T2DM inadequately controlled with metformin in the Chinese context. MATERIALS AND METHODS Economic outcomes were projected by using the validated Chinese Outcomes Model for T2DM (COMT). Efficacy and safety, medical expenditure, and utility data were derived from the literature, which were assigned to model variables for estimating the quality-adjusted life-years (QALYs) and costs as well as incremental cost-effectiveness ratios (ICERs). The analysis was conducted from the perspective of Chinese healthcare service providers. One-way and probabilistic sensitivity analyses were performed. Health outcomes and costs were discounted at 5%. RESULTS Relative to dapagliflozin 10 mg, treatment with canagliflozin 100 mg was associated with additional 0.015 expected life years per patients treated and 0.013 QALYs gained, which was driven by the reduced risk of macrovascular and microvascular complications over lifetime horizon. The incremental cost of canagliflozin 100 mg versus dapagliflozin 10 mg was US $-129, which indicated the canagliflozin 100 mg strategy was a dominant option. The univariate sensitivity analyses indicated that the results were sensitive to several model inputs. CONCLUSION These results suggested that canagliflozin was a cost-saving treatment option compared with dapagliflozin from the perspective of Chinese health care services providers for Chinese patients with T2DM who are inadequately controlled on metformin monotherapy.

Abstract
AIMS Information on the clinical efficacy of SGLT2 inhibitors in the Japanese population is limited. The aim of this single-arm, single-center, open-label study was to confirm the body weight- and fat mass-lowering effects of canagliflozin (CANA) and the accompanying improvement in insulin resistance in Japanese patients with Type 2 diabetes mellitus (T2DM). METHODS Thirty-eight patients were enrolled and administered 100 mg CANA once daily for 24 weeks. Blood and anthropometric parameters were examined before and after treatment. In a subset of patients, insulin sensitivity was assessed based on the glucose infusion rate (GIR) during a hyperinsulinemic euglycemic clamp test. RESULTS CANA treatment significantly decreased hemoglobin A1c, fasting plasma glucose, and plasma liver enzyme levels, and increased plasma adiponectin levels. In addition, a significant reduction in body weight, visceral and subcutaneous fat area, fat and lean mass, and liver steatosis was also observed. The change in plasma adiponectin levels significantly correlated with the changes in both body fat mass and visceral fat area. GIR increased from 3.25 ± 1.53 to 4.11 ± 1.30 mg/kg/min (P < 0.05). CONCLUSIONS CANA improved insulin resistance and decreased visceral fat mass in Japanese patients with T2DM.

Abstract
AIM Nonalcoholic fatty liver disease (NAFLD), including nonalcoholic steatohepatitis (NASH), is known to be associated with type 2 diabetes mellitus (T2DM) in high rate. The improvement in hepatic function due to sodium-glucose co-transporter 2 (SGLT2) inhibitors has been reported in T2DM patients with and without NAFLD. However, only a few studies have attempted to evaluate the role of SGLT2 inhibitors in T2DM patients with biopsy-proven NASH, and no detailed prospective studies including the individual hepatic fibrosis stage have been reported. Therefore, we investigated the effect of canagliflozin on hepatic function in T2DM patients with biopsy-confirmed NASH. METHODS T2DM patients with NASH (hepatic fibrosis stage 1-3 confirmed via liver biopsy, n=10) were enrolled and received canagliflozin (100 mg) once a day for 12 weeks. The primary end point was change in serum alanine aminotransferase (ALT) levels from baseline to week 12. Secondary end points were liver function/fibrosis markers, metabolic parameters, and safety. RESULTS The change in ALT from baseline to week 12 was -23.9 U/L (95% CI -48.1 to 0.3, P=0.0526). Significant improvements in several hepatic function/fibrosis markers, such as aspartate aminotransferase, fibrosis-4 index, and FM-fibro index, and metabolic parameters including hemoglobin A1c and body weight were found. No serious or liver-related adverse events were reported. Regarding individual patients, different trends in ALT-lowering effects between stage 1 and stage 2/3 subjects were observed; the degree of ALT-lowering effect tended to be greater in the stage 1 group than in the stage 2/3 group. CONCLUSION Our results suggest that canagliflozin is effective and well-tolerated in patients with T2DM and NASH. Canagliflozin may be useful for the treatment of T2DM patients with NASH, especially those in early stages of NASH.
