RESUMO
AIM: To evaluate whether sodium-glucose cotransporter 2 inhibitor (SGLT2i) therapy is associated with a reduction of renal events compared with other glucose-lowering drugs (oGLDs) among Japanese people with type 2 diabetes (T2D) and grade 3 (G3) chronic kidney disease (CKD) in a real-world clinical practice setting. MATERIALS AND METHODS: People with T2D who were newly prescribed an SGLT2i or an oGLD from April 2014 to November 2021 (without prior use of index drugs for ≥ 1 year prior to index date) and G3 CKD (estimated glomerular filtration rate [eGFR] ≥ 30 to < 60 mL/min/1.73 m2) were selected from the Medical Data Vision database (MDV-DB) and the Real-World Data database (RWD-DB). SGLT2i and oGLD users were matched (1:1) using propensity score on patient background characteristics. The primary endpoint was a composite of the development of end-stage kidney disease or a sustained decline in eGFR of 50% or more. Hazard ratios (HRs) were estimated using the Cox proportional hazards model. RESULTS: Overall, 3190 (1595 per group) patients in the MDV-DB and 2572 (1286 per group) patients in the RWD-DB were included in the analyses. The composite outcome was significantly lower in the SGLT2i group than in the oGLD group in the MDV-DB (HR 0.49, 95% confidence interval [CI] 0.33 to 0.74, P < 0.001) and in the RWD-DB (HR 0.57, 95% CI 0.37 to 0.88, P = 0.011). CONCLUSIONS: Japanese people with T2D and G3 CKD initiating an SGLT2i had a lower risk of renal events than people initiating an oGLD.

Sodium-dependent glucose transporter (SGLT) 2 is specifically expressed in the kidney, while SGLT1 is present in the kidneys and small intestine. SGLT2 inhibitors are a class of oral antidiabetic drugs that lower elevated plasma glucose levels by promoting the urinary excretion of excess glucose through the inhibition of renal glucose reuptake. The inhibition selectivity for SGLT2 over SGLT1 (SGLT2/1 selectivity) of marketed SGLT2 inhibitors is diverse, while SGLT2/1 selectivity of canagliflozin is relatively low. Although canagliflozin suppresses postprandial glucose levels, the degree of contribution for SGLT1 inhibition to this effect remains unproven. To analyze the effect of SGLT2 inhibitors on postprandial glucose level, we constructed a novel quantitative systems pharmacology (QSP) model, called human systemic glucose dynamics (HSGD) model, integrating intestinal absorption, metabolism, and renal reabsorption of glucose. This HSGD model reproduced the postprandial plasma glucose concentration-time profiles during a meal tolerance test under different clinical trial conditions. Simulations after canagliflozin administration showed a dose-dependent delay of time (Tmax,glc ) to reach maximum concentration of glucose (Cmax,glc ), and the delay of Tmax,glc disappeared when inhibition of SGLT1 was negated. In addition, contribution ratio of intestinal SGLT1 inhibition to the decrease in Cmax,glc was estimated to be 23%-28%, when 100 and 300 mg of canagliflozin are administered. This HSGD model enabled us to provide the partial contribution of intestinal SGLT1 inhibition to the improvement of postprandial hyperglycemia as well as to quantitatively describe the plasma glucose dynamics following SGLT2 inhibitors.

INTRODUCTION: Drugs often show differing pharmacokinetic (PK) profiles, such as higher plasma concentrations, in older people than in younger people owing to age-related decreases in physiological functions. However, it is difficult to evaluate the PK in older populations. Therefore, we simulated the plasma age-related changes in the PK of teneligliptin, a dipeptidyl peptidase-4 inhibitor, using physiologically based PK (PBPK) models. METHODS: The previously developed PBPK model was revalidated by comparison between simulated data and clinical study data that included older subjects (up to 75 years old). We then simulated the plasma concentration-time profiles for teneligliptin at a dose of 20 mg (single and multiple doses) in virtual Japanese (20-70 years old) and European descent (20-98 years old) subjects. PK parameters were calculated by race and age group. RESULTS: We confirmed the validity of the previous PBPK model by comparison between simulated data and clinical study data. In the evaluation of age-related changes in PK after single and multiple doses using the PBPK model, the area under the plasma concentration-time curve (AUC) of teneligliptin tended to increase slightly with age in both populations up to 70 years old. However, no clear age-related change in the maximum plasma concentration (Cmax) of teneligliptin was observed. In the European descent subjects aged ≥ 70 years, the AUC tended to increase but the ratio of the change in Cmax was smaller than that in AUC. In both populations, there were positive correlations between AUC and age, but not between Cmax and age. CONCLUSION: The simulation using a PBPK model showed a tendency for the AUC of teneligliptin to increase with age, whereas Cmax was less affected by age than AUC.
RESUMO
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. TRIAL REGISTRATION: JapicCTI-153048.
Canagliflozin is a sodiumglucose cotransporter 2 (SGLT2) inhibitor that lowers blood glucose levels by increasing urinary glucose excretion. It was approved for the management of blood glucose levels in patients with type 2 diabetes mellitus following clinical trials. However, clinical trials may not fully represent the safety or effectiveness of a drug in real-world clinical practice. Therefore, a 3-year post-marketing surveillance was performed in Japan to obtain safety and effectiveness data for a large group of 12,227 patients with type 2 diabetes mellitus and various demographic/clinical characteristics. Safety and effectiveness data were collected for up to 3 years while patients were treated with canagliflozin. Adverse drug reactions occurred in 10.73% of patients. The most common types of adverse drug reactions were those related to volume depletion (body fluid decreased), followed by genital infection, polyuria/pollakiuria (increased urination), and urinary tract infection. Adverse drug reactions tended to be more common in elderly patients and in patients with renal impairment. As expected, canagliflozin was associated with improvements in haemoglobin A1c, a marker of blood glucose control, in patients with type 2 diabetes, including in elderly patients and patients with moderate renal impairment. In this surveillance in real-world clinical practice, long-term treatment with canagliflozin raised no new safety concerns beyond the information already included in the Japanese package insert. Canagliflozin provides sustained glucose-lowering effects.

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.
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.

AIMS/INTRODUCTION: The sodium-glucose cotransporter 2 inhibitor, canagliflozin, reduced kidney failure and cardiovascular events in the Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial. We carried out a post-hoc analysis to evaluate the efficacy and safety of canagliflozin in a subgroup of participants in East and South-East Asian (EA) countries who are at high risk of renal complications. MATERIALS AND METHODS: Participants with an estimated glomerular filtration rate of 30 to <90 mL/min/1.73 m2 and urinary albumin-to-creatinine ratio of >300-5,000 mg/g were randomized to 100 mg of canagliflozin or a placebo. The effects of canagliflozin treatment on pre-specified efficacy and safety outcomes were examined using Cox proportional hazards regression between participants from EA countries (China, Japan, Malaysia, the Philippines, South Korea and Taiwan) and the remaining participants. RESULTS: Of 4,401 participants, 604 (13.7%) were from EA countries; 301 and 303 were assigned to the canagliflozin and placebo groups, respectively. Canagliflozin lowered the risk of primary outcome (composite of end-stage kidney disease, doubling of serum creatinine level, or renal or cardiovascular death) in EA participants (hazard ratio 0.54, 95% confidence interval 0.35-0.84). The effects of canagliflozin on renal and cardiovascular outcomes in EA participants were generally similar to those of the remaining participants. Safety outcomes were similar between the EA and non-EA participants. CONCLUSIONS: In the CREDENCE trial, the risk of renal and cardiovascular events was safely reduced in participants from EA countries at high risk of renal events.

AIMS/INTRODUCTION: The Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial has shown the effects of canagliflozin on preventing clinically important kidney outcomes in patients with type 2 diabetes mellitus and chronic kidney disease; however, not many Japanese patients were included in the trial. The present study evaluated the efficacy and safety of canagliflozin in Japanese chronic kidney disease patients with type 2 diabetes mellitus. MATERIALS AND METHODS: In this multicenter, randomized, double-blind, placebo-controlled, parallel-group, phase III study, chronic kidney disease patients with type 2 diabetes mellitus were randomly assigned to receive either 100 mg canagliflozin or a matching placebo once daily for 104 weeks. The primary efficacy end-point was the incidence of a 30% decline in estimated glomerular filtration rate. RESULTS: Overall, 308 patients were randomized to the canagliflozin (n = 154) and placebo (n = 154) groups. The incidence of a 30% decline in estimated glomerular filtration rate at week 104 was 18.2% and 29.5%, respectively, and the point estimate of the intergroup difference (placebo - canagliflozin) was 11.3% (95% confidence interval 1.2-21.5, P = 0.029), which was significant. The overall incidence of adverse events was similar in the two groups. CONCLUSIONS: This study suggests that canagliflozin safely reduces the risk of end-stage renal disease in Japanese chronic kidney disease patients with type 2 diabetes mellitus.
