Abstract
One of the key pharmacokinetic properties of most small molecule drugs is their ability to bind to serum proteins. Unbound or free drug is responsible for pharmacological activity while the balance between free and bound drug can impact drug distribution, elimination, and other safety parameters. In the hepatic impairment (HI) and renal impairment (RI) clinical studies, unbound drug concentration is often assessed; however, the relevance and impact of the protein binding (PB) results is largely limited. We analyzed published clinical safety and pharmacokinetic studies in subjects with HI or RI with PB assessment up to October 2022 and summarized the contribution of PB results on their label dose recommendations. Among drugs with HI publication, 32% (17/53) associated product labels include PB results in HI section. Of these, the majority (9/17, 53%) recommend dose adjustments consistent with observed PB change. Among drugs with RI publication, 27% (12/44) of associated product labels include PB results in RI section with the majority (7/12, 58%) recommending no dose adjustment, consistent with the reported absence of PB change. PB results were found to be consistent with a tailored dose recommendation in 53% and 58% of the approved labels for HI and RI section, respectively. We further discussed the interpretation challenges of PB results, explored treatment decision factors including total drug concentration, exposure-response relationships, and safety considerations in these case examples. Collectively, comprehending the alterations in free drug levels in HI and RI informs treatment decision through a risk-based approach.

Abstract
Sodium-glucose cotransporter 2 (SGLT2) inhibitors reduce heart failure events by direct action on the failing heart that is independent of changes in renal tubular function. In the failing heart, nutrient transport into cardiomyocytes is increased, but nutrient utilization is impaired, leading to deficient ATP production and the cytosolic accumulation of deleterious glucose and lipid by-products. These by-products trigger downregulation of cytoprotective nutrient-deprivation pathways, thereby promoting cellular stress and undermining cellular survival. SGLT2 inhibitors restore cellular homeostasis through three complementary mechanisms: they might bind directly to nutrient-deprivation and nutrient-surplus sensors to promote their cytoprotective actions; they can increase the synthesis of ATP by promoting mitochondrial health (mediated by increasing autophagic flux) and potentially by alleviating the cytosolic deficiency in ferrous iron; and they might directly inhibit glucose transporter type 1, thereby diminishing the cytosolic accumulation of toxic metabolic by-products and promoting the oxidation of long-chain fatty acids. The increase in autophagic flux mediated by SGLT2 inhibitors also promotes the clearance of harmful glucose and lipid by-products and the disposal of dysfunctional mitochondria, allowing for mitochondrial renewal through mitochondrial biogenesis. This Review describes the orchestrated interplay between nutrient transport and metabolism and nutrient-deprivation and nutrient-surplus signalling, to explain how SGLT2 inhibitors reverse the profound nutrient, metabolic and cellular abnormalities observed in heart failure, thereby restoring the myocardium to a healthy molecular and cellular phenotype.

Abstract
Diabetes drives an increasing burden of cardiovascular and renal disease worldwide, motivating the search for new hypoglycemic agents that confer cardiac and renal protective effects. Although initially developed as hypoglycemic agents, sodium-glucose co-transporter 2 (SGLT-2) inhibitors have since been studied in patients with and without diabetes for the management of heart failure and chronic kidney disease. A growing body of evidence supports the efficacy and safety of SGLT-2 inhibitors in patients with chronic kidney disease (CKD), based on complex mechanisms of action that extend far beyond glucosuria and that confer beneficial effects on cardiovascular and renal hemodynamics, fibrosis, inflammation, and end-organ protection. This review focuses on the pharmacology and pathophysiology of SGLT-2 inhibitors in patients with CKD, as well as their cardiovascular and renal effects in this population. We are focusing on the five agents that have been tested in cardiovascular outcome trials and that have been approved either in Europe or in North America: empagliflozin, dapagliflozin, canagliflozin, ertugliglozin, and sotagliflozin.

Abstract
INTRODUCTION Diabetes is the most common cause of end stage kidney disease. Therapies such as sodium-glucose co-transporter-2 inhibitors have been identified over the last decade as effective oral hypoglycemic agents that also confer additional cardio and kidney protection. Knowledge of their mechanism of action and impact on patients with diabetes and albuminuria is vital in galvanizing prescriber confidence and increasing clinical uptake. AREAS COVERED This manuscript discusses the pathophysiology of diabetic kidney disease, patho-physiological mechanisms for sodium-glucose co-transporter-2 inhibitors, and their impact on patients with Type 2 diabetes mellitus and albuminuric kidney disease. EXPERT OPINION Sodium-glucose co-transporter-2 inhibitors reduce albuminuria with consequent benefits on cardiovascular and kidney outcomes in patients with diabetes and severe albuminuria. Whilst they have been incorporated into guidelines, the uptake of these agents into clinical practice has been slow. Increasing the uptake of these agents into clinical practice is necessary to improve outcomes for the large number of patients with diabetic kidney disease globally.

Abstract
(1) The cardio-reno-metabolic benefits of the SGLT2 inhibitors canagliflozin (cana), dapagliflozin (dapa), ertugliflozin (ertu), and empagliflozin (empa) have been demonstrated, but it remains unclear whether they exert different off-target effects influencing clinical profiles. (2) We aimed to investigate the effects of SGLT2 inhibitors on mitochondrial function, cellular glucose-uptake (GU), and metabolic pathways in human-umbilical-vein endothelial cells (HUVECs). (3) At 100 µM (supra-pharmacological concentration), cana decreased ECAR by 45% and inhibited GU (IC5o: 14 µM). At 100 µM and 10 µM (pharmacological concentration), cana increased the ADP/ATP ratio, whereas dapa and ertu (3, 10 µM, about 10× the pharmacological concentration) showed no effect. Cana (100 µM) decreased the oxygen consumption rate (OCR) by 60%, while dapa decreased it by 7%, and ertu and empa (all 100 µM) had no significant effect. Cana (100 µM) inhibited GLUT1, but did not significantly affect GLUTs’ expression levels. Cana (100 µM) treatment reduced glycolysis, elevated the amino acids supplying the tricarboxylic-acid cycle, and significantly increased purine/pyrimidine-pathway metabolites, in contrast to dapa (3 µM) and ertu (10 µM). (4) The results confirmed cana´s inhibition of mitochondrial activity and GU at supra-pharmacological and pharmacological concentrations, whereas the dapa, ertu, and empa did not show effects even at supra-pharmacological concentrations. At supra-pharmacological concentrations, cana (but not dapa or ertu) affected multiple cellular pathways and inhibited GLUT1.

The differential effects of ertugliflozin on glucosuria and natriuresis biomarkers: Prespecified analyses from VERTIS CV. Diabetes Obes Metab 2022; 24:1114-1122. [PMID: 35233908 DOI: 10.1111/dom.14677] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Revised: 02/17/2022] [Accepted: 02/28/2022] [Indexed: 11/27/2022]
Abstract
AIMS This prespecified exploratory analyses from VERTIS CV (NCT01986881) aimed to assess the effects of the sodium-glucose cotransporter-2 (SGLT2) inhibitor ertugliflozin on glucosuria-related (glycated haemoglobin [HbA1c], uric acid, body weight) and natriuresis-related (blood pressure, haemoglobin, haematocrit, serum albumin) biomarkers according to kidney function risk category. MATERIALS AND METHODS Patients with type 2 diabetes and atherosclerotic cardiovascular disease were randomized to placebo, ertugliflozin 5 mg, or ertugliflozin 15 mg (1:1:1). Analyses compared placebo (n = 2747) versus ertugliflozin (pooled; n = 5499) on glucosuria- and natriuresis-related biomarkers according to baseline estimated glomerular filtration rate (eGFR) subgroup and Kidney Disease: Improving Global Outcomes in Chronic Kidney Disease (KDIGO CKD) risk category. RESULTS Patients were classified according to KDIGO CKD low- (49%), moderate- (32%) and high-/very-high-risk categories (19%), and eGFR groups 1 (25%), 2 (53%) and 3 (19%). At Week 18, the high-/very-high-risk category had a smaller placebo-subtracted least squares mean (LSM) change from baseline (95% confidence interval) in HbA1c (-0.34 [-0.43, -0.25]) compared with the low- and moderate-risk categories (-0.54 [-0.60, -0.49] and - 0.47 [-0.54, -0.40], respectively). This pattern was maintained throughout the study (Pinteraction = 0.0001). Similar patterns based on baseline eGFR G stage were observed. Placebo-subtracted LSM changes from baseline in uric acid were lowest in the high-/very-high-risk category at Weeks 6 and 18, but the pattern was not maintained after Week 156 (Pinteraction = 0.15). Effects of ertugliflozin on body weight and natriuresis-related biomarkers did not differ across KDIGO CKD categories. CONCLUSIONS In VERTIS CV, ertugliflozin was associated with physiologically favourable changes in glucosuria- and natriuresis-related biomarkers. Glycaemic efficacy of ertugliflozin was attenuated in patients with higher chronic kidney disease (CKD) risk. Effects on other biomarkers were consistent, regardless of CKD risk stage.

Abstract
Chronic kidney disease is a prevalent complication of type 2 diabetes mellitus (T2DM). Sodium-glucose cotransporter type 2 inhibitors (SGLT2is) have a unique mode of action targeting the kidney. As their glucose-lowering potency declines with the reduction in estimated glomerular filtration rate, their clinical use in patients with T2DM with chronic kidney disease has been submitted to restriction. However, recent observations demonstrated that SGLT2is reduce the progression of renal impairment in patients with mild-to-moderate chronic kidney disease, with or without albuminuria. Furthermore, SGLT2is reduce the incidence of cardiovascular events in patients with T2DM at high cardiovascular risk, independently of baseline estimated glomerular filtration rate. Thus, recent guidelines recommend the prescription of SGLT2is in patients with T2DM with mild-to-moderate chronic kidney disease defined by an estimated glomerular filtration rate between ≥ 30 and < 90 mL/min/1.73 m2 and/or albuminuria. The present comprehensive review describes the pharmacokinetic/pharmacodynamic properties of SGLT2is commercialised worldwide and in Japan in patients with T2DM with mild, moderate and severe chronic kidney disease. Drug exposure increases when the estimated glomerular filtration rate declines but without a clear-cut relationship with the severity of chronic kidney disease and in a rather moderate amplitude that most often does not require a dose reduction in the presence of mild-to-moderate chronic kidney disease. The urinary glucose excretion steadily declines with the reduction in estimated glomerular filtration rate. This may explain a lower effect on glucose control, yet the positive effects on body weight and blood pressure still remain. The efficacy and safety of these SGLT2is are analysed among patients with stages 3a and 3b chronic kidney disease in placebo-controlled randomised clinical trials, with almost similar results in Asian and non-Asian individuals with T2DM. In summary, there is no reason not to prescribe SGLT2is in patients with T2DM with mild-to-moderate chronic kidney disease, especially if the aim is to benefit from cardiovascular and/or renal protection.

Abstract
Ertugliflozin, a selective inhibitor of sodium-glucose cotransporter 2 (SGLT2), is approved in the US, EU, and other regions for the treatment of adults with type 2 diabetes mellitus (T2DM). This review summarizes the ertugliflozin pharmacokinetic (PK) and pharmacodynamic data obtained during phase I clinical development, which supported the registration and labeling of this drug. The PK of ertugliflozin was similar in healthy subjects and patients with T2DM. Oral absorption was rapid, with time to peak plasma concentrations (Tmax) occurring at 1 h (fasted) and 2 h (fed) postdose. The terminal phase half-life ranged from 11 to 18 h and steady-state concentrations were achieved by 6 days after initiating once-daily dosing. Ertugliflozin exposure increased in a dose-proportional manner over the tested dose range of 0.5–300 mg. Ertugliflozin is categorized as a Biopharmaceutical Classification System Class I drug with an absolute bioavailability of ~ 100% under fasted conditions. Administration of the ertugliflozin 15 mg commercial tablet with food resulted in no meaningful effect on ertugliflozin area under the plasma concentration–time curve (AUC), but decreased peak concentrations (Cmax) by 29%. The effect on Cmax is not clinically relevant and ertugliflozin can be administered without regard to food. Mild, moderate, and severe renal impairment were associated with a ≤ 70% increase in ertugliflozin exposure relative to subjects with normal renal function, and no dose adjustment in renal impairment patients is needed based on PK results. Consistent with the mechanism of action of SGLT2 inhibitors, 24-h urinary glucose excretion decreased with worsening renal function. In subjects with moderate hepatic impairment, a decrease in AUC (13%) relative to subjects with normal hepatic function was observed and not considered clinically relevant. Concomitant administration of metformin, sitagliptin, glimepiride, or simvastatin with ertugliflozin did not have clinically meaningful effects on the PK of ertugliflozin or the coadministered medications. Coadministration of rifampin decreased ertugliflozin AUC and Cmax by 39% and 15%, respectively, and is not expected to affect efficacy in a clinically meaningful manner. This comprehensive evaluation supports administration to patients with T2DM without regard to prandial status and with no dose adjustments for coadministration with commonly prescribed drugs, or in patients with renal impairment or mild-to-moderate hepatic impairment based on ertugliflozin PK.

Abstract
Ertugliflozin, a sodium‐glucose cotransporter 2 inhibitor, is approved for treatment of type 2 diabetes. Two population pharmacokinetic (PK) analyses were conducted, using data from up to 17 phase 1 to 3 studies, to characterize ertugliflozin PK parameters in select ethnic subgroups: (1) East/Southeast (E/SE) Asian vs non‐E/SE Asian subjects; (2) Asian subjects from mainland China vs Asian subjects from the rest of the world and non‐Asian subjects. A 2‐compartment model with first‐order absorption, lag time, and first‐order elimination was fitted to the observed data. For the E/SE Asian vs non‐E/SE Asian analysis (13 692 PK observations from 2276 subjects), E/SE Asian subjects exhibited a 17% increase in apparent clearance (CL/F) and 148% increase in apparent central volume of distribution (Vc/F) vs non‐E/SE Asian subjects. However, individual post hoc CL/F values were similar between groups when body weight differences were considered. For the second analysis (16 018 PK observations from 2620 subjects), compared with non‐Asian subjects, CL/F was similar while Vc/F increased by 44% in Asian subjects from mainland China and both CL/F and Vc/F increased in Asian subjects from the rest of the world (8% and 115%, respectively) vs non‐Asian subjects. Increases in Vc/F would decrease the ertugliflozin maximum concentration but would not impact area under the concentration‐time curve. Therefore, the differences in CL/F (area under the concentration‐time curve) and Vc/F were not considered clinically relevant or likely to result in meaningful ethnic differences in the PK of ertugliflozin.

Abstract
Ertugliflozin, a sodium‐glucose cotransporter 2 inhibitor, is primarily metabolized via glucuronidation by the uridine 5′‐diphospho‐glucuronosyltransferase (UGT) isoform UGT1A9. This noncompartmental meta‐analysis of ertugliflozin pharmacokinetics evaluated the relationship between ertugliflozin exposure and dose, and the effect of UGT1A9 genotype on ertugliflozin exposure. Pharmacokinetic data from 25 phase 1 studies were pooled. Structural models for dose proportionality described the relationship between ertugliflozin area under the plasma concentration‐time curve (AUC) or maximum observed plasma concentration (Cmax) and dose. A structural model for the UGT1A9 genotype described the relationship between ertugliflozin AUC and dose, with genotype information on 3 UGT1A9 polymorphisms (UGT1A9‐2152, UGT1A9*3, UGT1A9*1b) evaluated as covariates from the full model. Ertugliflozin AUC and Cmax increased in a dose‐proportional manner over the dose range of 0.5‐300 mg, and population‐predicted AUC and Cmax values for the 5‐ and 15‐mg ertugliflozin tablets administered in the fasted state demonstrated good agreement with the observed data. The largest change in ertugliflozin AUC was in subjects carrying the UGT1A9*3 heterozygous variant, with population‐predicted AUC (90% confidence interval) values of 485 ng·h/mL (458 to 510 ng·h/mL) and 1560 ng·h/mL (1480 to 1630 ng·h/mL) for ertugliflozin 5 and 15 mg, respectively, compared with 436 ng·h/mL (418 to 455 ng·h/mL) and 1410 ng·h/mL (1350 to 1480 ng·h/mL), respectively, in wild‐type subjects. Overall, the mean effects of the selected UGT1A9 variants on ertugliflozin AUC were within ±10% of the wild type. UGT1A9 genotype did not have any clinically meaningful effects on ertugliflozin exposure in healthy subjects. No ertugliflozin dose adjustment would be required in patients with the UGT1A9 variants assessed in this study.

Effects of ertugliflozin on kidney composite outcomes, renal function and albuminuria in patients with type 2 diabetes mellitus: an analysis from the randomised VERTIS CV trial. Diabetologia 2021; 64:1256-1267. [PMID: 33665685 PMCID: PMC8099851 DOI: 10.1007/s00125-021-05407-5] [Citation(s) in RCA: 88] [Impact Index Per Article: 29.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Accepted: 12/11/2020] [Indexed: 01/03/2023]
Abstract
AIMS/HYPOTHESIS In previous work, we reported the HR for the risk (95% CI) of the secondary kidney composite endpoint (time to first event of doubling of serum creatinine from baseline, renal dialysis/transplant or renal death) with ertugliflozin compared with placebo as 0.81 (0.63, 1.04). The effect of ertugliflozin on exploratory kidney-related outcomes was evaluated using data from the eValuation of ERTugliflozin effIcacy and Safety CardioVascular outcomes (VERTIS CV) trial (NCT01986881). METHODS Individuals with type 2 diabetes mellitus and established atherosclerotic CVD were randomised to receive ertugliflozin 5 mg or 15 mg (observations from both doses were pooled), or matching placebo, added on to existing treatment. The kidney composite outcome in VERTIS CV (reported previously) was time to first event of doubling of serum creatinine from baseline, renal dialysis/transplant or renal death. The pre-specified exploratory composite outcome replaced doubling of serum creatinine with sustained 40% decrease from baseline in eGFR. In addition, the impact of ertugliflozin on urinary albumin/creatinine ratio (UACR) and eGFR over time was assessed. RESULTS A total of 8246 individuals were randomised and followed for a mean of 3.5 years. The exploratory kidney composite outcome of sustained 40% reduction from baseline in eGFR, chronic kidney dialysis/transplant or renal death occurred at a lower event rate (events per 1000 person-years) in the ertugliflozin group than with the placebo group (6.0 vs 9.0); the HR (95% CI) was 0.66 (0.50, 0.88). At 60 months, in the ertugliflozin group, placebo-corrected changes from baseline (95% CIs) in UACR and eGFR were -16.2% (-23.9, -7.6) and 2.6 ml min-1 [1.73 m]-2 (1.5, 3.6), respectively. Ertugliflozin was associated with a consistent decrease in UACR and attenuation of eGFR decline across subgroups, with a suggested larger effect observed in the macroalbuminuria and Kidney Disease: Improving Global Outcomes in Chronic Kidney Disease (KDIGO CKD) high/very high-risk subgroups. CONCLUSIONS/INTERPRETATION Among individuals with type 2 diabetes and atherosclerotic CVD, ertugliflozin reduced the risk for the pre-specified exploratory composite renal endpoint and was associated with preservation of eGFR and reduced UACR.

Abstract
Model-informed drug development (MIDD) is critical in all stages of the drug-development process and almost all regulatory submissions for new agents incorporate some form of modeling and simulation. This review describes the MIDD approaches used in the end-to-end development of ertugliflozin, a sodium-glucose cotransporter 2 inhibitor approved for the treatment of adults with type 2 diabetes mellitus. Approaches included (1) quantitative systems pharmacology modeling to predict dose-response relationships, (2) dose-response modeling and model-based meta-analysis for dose selection and efficacy comparisons, (3) population pharmacokinetics (PKs) modeling to characterize PKs and quantify population variability in PK parameters, (4) regression modeling to evaluate ertugliflozin dose-proportionality and the impact of uridine 5'-diphospho-glucuronosyltransferase (UGT) 1A9 genotype on ertugliflozin PKs, and (5) physiologically-based PK modeling to assess the risk of UGT-mediated drug-drug interactions. These end-to-end MIDD approaches for ertugliflozin facilitated decision making, resulted in time/cost savings, and supported registration and labeling.

Abstract
Patients with Type 2 Diabetes (T2D) are at risk of developing macrovascular (cardiac, cerebrovascular, peripheral arterial disease) and microvascular (nephropathy, neuropathy, retinopathy) complications. Glycemic control improves only microvascular outcomes. However, some SGLT-2 inhibitors and GLP1-R agonists have proven beneficial in macrovascular conditions. Canagliflozin is an SGLT2 inhibitor that provides sustained reductions in HbA1c, blood pressure and weight. Remarkably, as CANVAS program and CREDENCE trial demonstrated, canagliflozin promotes significant reductions in the frequency of atherosclerotic cardiovascular events, hospitalizations for heart failure and renal outcomes. In addition, real-world studies have confirmed the results of clinical trials in clinical practice. Therefore, canagliflozin should be considered a first-line therapy in the management of T2D patients in order to reduce both micro- and macrovascular complications.

Abstract
Ertugliflozin, a sodium-glucose cotransporter 2 inhibitor, is approved for treatment of type 2 diabetes. This randomized, double-blind (sponsor-open) study in healthy Japanese subjects and open-label study in Western subjects assessed ertugliflozin pharmacokinetics and pharmacodynamics. Cohort A received 3 ascending single doses of ertugliflozin (1, 5, and 25 mg; n = 6 Japanese, n = 6 Western) or placebo (n = 3 Japanese) under fasted conditions. Cohort B received multiple once-daily doses of ertugliflozin 25 mg (n = 6 Japanese) or placebo (n = 3 Japanese) for 7 days under fed conditions. For Japanese subjects in Cohort A, maximum plasma concentrations (Cmax ) were observed 1 to 1.5 hours after dosing, and apparent mean terminal half-life was 12.4 to 13.6 hours. The ratios of the geometric means (Japanese/Western) for ertugliflozin 1-, 5-, and 25-mg single doses were 95.94%, 99.66%, and 90.32%, respectively, for area under the plasma concentration-time curve and 107.59%, 97.47%, and 80.04%, respectively, for Cmax . Area under the plasma concentration-time curve and Cmax increased in a dose-proportional manner. For Cohort B, Cmax was observed 2.5 hours after dosing (days 1 and 7), and steady state was reached by day 4. The 24-hour urinary glucose excretion was dose dependent. Ertugliflozin was generally well tolerated. There were no meaningful differences in exposure, urinary glucose excretion, and safety between Japanese and Western subjects.

Abstract
The sodium-glucose cotransporter 2 inhibitor ertugliflozin is metabolized by the uridine 5'-diphospho-glucuronosyltransferase (UGT) isozymes UGT1A9 and UGT2B4/2B7. This analysis evaluated the drug-drug interaction (DDI) following co-administration of ertugliflozin with the UGT inhibitor mefenamic acid (MFA) using physiologically-based pharmacokinetic (PBPK) modeling. The ertugliflozin modeling assumptions and parameters were verified using clinical data from single-dose and multiple-dose studies of ertugliflozin in healthy volunteers, and the PBPK fraction metabolized assignments were consistent with human absorption, distribution, metabolism, and excretion results. The model for MFA was developed using clinical data, and in vivo UGT inhibitory constant values were estimated using the results from a clinical DDI study with MFA and dapagliflozin, a UGT1A9 and UGT2B4/2B7 substrate in the same chemical class as ertugliflozin. Using the verified compound files, PBPK modeling predicted an ertugliflozin ratio of area under the plasma concentration-time curves (AUCR ) of 1.51 when co-administered with MFA.

Abstract
More than 422 million people worldwide have diabetes, with 90–95% having type 2 diabetes (T2D). Glycemic control of T2D has demonstrated reductions in microvascular complications but recent data have demonstrated improvements in macrovascular outcomes with sodium–glucose cotransporter 2 (SGLT2) inhibitors. Ertugliflozin is the most recent SGLT2 inhibitor approved in the USA and Europe for the treatment of T2D. This narrative review aims to present and discuss the efficacy, safety, cardiovascular (CV), and renal outcomes related to the use of ertugliflozin in T2D. Ertugliflozin has been evaluated in eight clinical trials (n=5248) with a focus on glycemic control. These trials have demonstrated improvement in glycosylated hemoglobin (0.6–1%), fasting plasma glucose (30–50 mg/dL), 2-hour postprandial glucose (60–70 mg/dL), decreased body weight (2–3 kg), and lowering of blood pressure (3–5 mmHg) in patients with T2D when ertugliflozin is used as monotherapy or in addition to metformin, sitagliptin, insulin, and/or sulfonylureas. The findings from the VERTIS-CV trial (n=8246) were recently published and demonstrated that ertugliflozin use in patients with T2D and atherosclerotic CV disease is safe but did not demonstrate superiority in the lowering of major CV events compared to placebo. Other SGLT2 inhibitors, such as empagliflozin and canagliflozin, have demonstrated this benefit. The VERTIS-CV trial demonstrated that the use of ertugliflozin led to a decrease in the number of hospitalizations for heart failure and this lends further support that this benefit is a class effect of SGLT2 inhibitors.

Abstract
Ertugliflozin is a selective sodium‐glucose cotransporter 2 inhibitor approved as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus (T2DM). A population pharmacokinetic (popPK) model was developed to characterize the pharmacokinetics (PK) of ertugliflozin and quantify the influence of intrinsic (eg, body weight, age, sex, race, estimated glomerular filtration rate [eGFR], T2DM) and extrinsic (eg, food) covariates on the PK parameters of ertugliflozin. The analysis was conducted using data from 15 clinical studies (phases 1‐3) enrolling healthy subjects and patients with T2DM, which included 13,691 PK observations from 2276 subjects and was performed using nonlinear mixed‐effects modeling. A 2‐compartment popPK model with first‐order absorption and a lag time and first‐order elimination, described the plasma concentration–time profile of ertugliflozin after single and multiple dosing in healthy subjects and in patients with T2DM. Apparent clearance increased with increasing body weight and eGFR, was slightly lower in patients with T2DM and females, and was slightly higher in Asians. Apparent central volume of distribution increased with increasing body weight and was higher in females and Asians. Administration of ertugliflozin with food decreased the absorption rate constant (ka) and relative bioavailability (F1) compared with fasted. When ertugliflozin was administered without regard to food, estimates of ka and F1 were similar to those for administration with food. The popPK model successfully characterized ertugliflozin exposure in healthy subjects and patients with T2DM. None of the covariates evaluated had a clinically relevant effect on ertugliflozin PK.

Abstract
A fixed‐dose combination (FDC) product of a selective sodium‐glucose cotransporter 2 inhibitor ertugliflozin and immediate‐release metformin is approved for type 2 diabetes mellitus in the United States, European Union countries, Canada, and other countries. Two studies were conducted to assess the bioequivalence of metformin in the ertugliflozin/metformin FDC tablets to the corresponding doses of Canadian‐sourced metformin (Glucophage) coadministered with ertugliflozin. Both studies were phase 1 randomized, open‐label, 2‐period, single‐dose crossover studies (n = 32) in which healthy subjects received an ertugliflozin/metformin FDC tablet (2.5/500 mg or 7.5/850 mg) and the respective doses of the individual components (ertugliflozin coadministered with Canadian‐sourced metformin) under fasted (n = 18) or fed (n = 14) conditions. Blood samples were collected 72 hours postdose to determine metformin concentrations. The 90% confidence intervals were within the bioequivalence acceptance criteria for the adjusted geometric mean ratios (FDC:coadministered) for metformin area under the plasma concentration‐time curve from time zero to time t, where t is the last point with a measurable concentration and peak observed plasma concentration for both dose strengths under fasted and fed conditions. All study medications were well tolerated. Bioequivalence was demonstrated for the metformin component of the ertugliflozin/metformin FDC tablets and the corresponding doses of the Canadian‐sourced metformin coadministered with ertugliflozin.

Abstract
Sodium-glucose cotransporter 2 (SGLT2) inhibitors are a major advance in the fields of diabetology, nephrology, and cardiology. The cardiovascular and renal benefits of SGLT2 inhibitors are likely largely independent of their glycaemic effects, and this understanding is central to the use of these agents in the high-risk population of people with type 2 diabetes and chronic kidney disease. There are a number of potential safety issues associated with the use of SGLT2 inhibitors. These include the rare but serious risks of diabetic ketoacidosis and necrotising fasciitis of the perineum. The data regarding a possibly increased risk of lower limb amputation and fracture with SGLT2 inhibitor therapy are conflicting. This article aims to explore the potential safety issues associated with the use of SGLT2 inhibitors, with a particular focus on the safety of these drugs in people with type 2 diabetes and chronic kidney disease. We discuss strategies that clinicians can implement to minimise the risk of adverse effects including diabetic ketoacidosis and volume depletion. Risk mitigation strategies with respect to SGLT2 inhibitor-associated diabetic ketoacidosis are of particular importance during the current coronavirus disease 2019 (COVID-19) pandemic.

Abstract
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.

Abstract
A fixed-dose combination (FDC) tablet of ertugliflozin, a selective inhibitor of sodium-glucose cotransporter 2, and sitagliptin, a dipeptidyl peptidase-4 inhibitor, was developed for the treatment of patients with type 2 diabetes mellitus. Four studies were conducted under fasted conditions to demonstrate bioequivalence of ertugliflozin/sitagliptin FDC tablets and individual components at respective strengths when coadministered in healthy subjects. All studies had open-label, randomized, 2-period, 2-sequence, single-dose crossover designs. In each study 18 or 19 subjects were enrolled and received an ertugliflozin/sitagliptin FDC tablet (5 mg/50 mg, 5 mg/100 mg, 15 mg/50 mg, or 15 mg/100 mg) and corresponding strengths of ertugliflozin and sitagliptin coadministered as individual components. For both ertugliflozin and sitagliptin, the 90%CIs for the ratio (FDC:coadministration) of geometric means for area under the plasma concentration-time profile from time 0 extrapolated to infinite time, and maximum observed plasma concentration, were within acceptance criteria for bioequivalence (80% to 125%). All adverse events were mild in intensity. The 4 studies demonstrated that each strength of FDC tablet is bioequivalent to the respective dose of coadministered individual components. This indicates that the known efficacy and tolerability of ertugliflozin and sitagliptin when coadministered can be translated to the use of a FDC formulation.

Abstract
PURPOSE Sodium-glucose cotransporter 2 (SGLT2) inhibitors have important cardiovascular and renal benefits in adults with type 2 diabetes who have or are at high risk of cardiovascular and renal disease. These benefits are seen in patients with impaired renal function where the glucose-lowering effects are not observed. Here, we review the pharmacokinetics and pharmacology of SGLT2 inhibitors in relation to cardiovascular and renal outcomes in patients with chronic kidney disease (CKD). METHODS We searched PubMed and EMBASE for original research, meta-analyses and review articles relevant to the pharmacokinetics, and cardiac and renal outcomes of SGLT2 inhibitors published up until June 2019. Specialist society guidelines and publications were also consulted. RESULTS Renal impairment is currently a contraindication to SGLT2 inhibitor use largely due to limited anti-hyperglycaemic efficacy. However, in cardiovascular outcome trials, and a dedicated renal outcome trial, cardiovascular and renal benefits were seen in participants with CKD suggesting that mechanisms underlying the cardiovascular and renal benefits of SGLT2 inhibitors are likely largely independent of the glucose-lowering action of these agents. CONCLUSIONS Despite minimal glycaemic benefits in patients with type 2 diabetes and stage 3 CKD, the cardiovascular and renal benefits of these agents are preserved in this group of patients. Whether these agents have cardiovascular and renal benefits in patients with stage 4 CKD and patients with non-diabetic CKD needs further research.

A PK/PD study comparing twice-daily to once-daily dosing regimens of ertugliflozin in healthy subjects
. Int J Clin Pharmacol Ther 2019; 57:207-216. [PMID: 30802200 PMCID: PMC6528385 DOI: 10.5414/cp203343] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/20/2019] [Indexed: 12/18/2022] Open
Abstract
OBJECTIVE Ertugliflozin is approved in the US and European Union as a stand-alone product for adults with type 2 diabetes mellitus as once daily (QD) dosing. The approved fixed-dose combination (FDC) of ertugliflozin and immediate-release metformin is dosed twice daily (BID). This study assessed steady-state pharmacokinetics (PK; area under the concentration-time curve over 24 hours (AUC24)) and pharmacodynamics (PD; urinary glucose excretion over 24 hours (UGE24)) for ertugliflozin 5 and 15 mg total daily doses administered BID or QD. MATERIALS AND METHODS In this open-label, two-cohort, randomized, multiple-dose, crossover study, healthy subjects received ertugliflozin 2.5 mg BID and 5 mg QD (n = 28) or ertugliflozin 7.5 mg BID and 15 mg QD (n = 22) for 6 days. Plasma and urine samples were collected for 24 hour post morning dose on day 6 in each period. RESULTS The geometric mean ratio (GMR) (90% CI) of ertugliflozin AUC24 was 100.8% (98.8%, 102.8%) for 2.5 mg BID vs. 5 mg QD, and 99.7% (97.1%, 102.5%) for 7.5 mg BID vs. 15 mg QD. GMR (90% CI) of UGE24 for BID vs. QD administration was 110.2% (103.0%, 117.9%) at a total daily dose of 5 mg, and 102.8% (97.7%, 108.1%) at 15 mg. The 90% CIs of the GMR of AUC24 and UGE24 for BID vs. QD dosing were within the acceptance range for equivalence (80 - 125%) and the prespecified criterion for similarity (70 - 143%), respectively. All treatments were well tolerated. CONCLUSION There are no clinically meaningful differences in steady-state PK or PD between ertugliflozin BID and QD regimens at total daily doses of 5 and 15 mg, supporting BID administration of ertugliflozin as a component of the ertugliflozin/metformin (immediate-release) FDC.

Preparation of a nanoscale dihydromyricetin-phospholipid complex to improve the bioavailability: in vitro and in vivo evaluations. Eur J Pharm Sci 2019; 138:104994.

Abstract
Dihydromyricetin (DMY), a flavanonol compound found as the most abundant and bioactive constituent in Ampelopsis grossedentata (Hand-Mazz) W.T. Wang, possesses numerous pharmacological activities, such as antioxidant, anti-inflammation, anticancer, anti-microbial, hypoglycemic and hypolipidemic effects, and so on. Recently, DMY shows a promising potential to develop as an agent for the prevention and treatment of Type 2 diabetes mellitus (T2DM). However, the low oral bioavailability of DMY was one of the special concerns to be resolved for its clinical applications. In this study, DMY phospholipid complex (DMY-HSPC COM) was prepared by the solvent evaporation technique and optimized with DMY combination ratio. Scanning electron microscopy (SEM), X-ray powder diffraction (XRPD), differential scanning calorimetry (DSC), and Fourier transform infrared spectrophotometry (FT-IR) were carried to characterize the formation of DMY-HSPC COM. The particle size, zeta potential, drug loading and solubility of DMY-HSPC COM were further investigated. The phospholipid complex technology could significantly improve the solubility of DMY. Pharmacokinetic study results of DMY-HSPC COM in healthy SD rats and T2DM rats demonstrated that the oral bioavailability was significantly increased when compared with pure DMY as well, which could be attributed to the improvement of the aqueous solubility of the complex, absorption promotion and a probable decrease in intestinal and hepatic metabolism. In addition, when compared with healthy SD rats, pharmacokinetic parameters of pure DMY and DMY-HSPC COM showed significant difference in T2DM rats. Thus, phospholipid complex technology holds a promising potential for increasing the oral bioavailability of DMY.

Abstract
Ertugliflozin (ERTU) is a novel, potent, and highly selective sodium glucose cotransporter 2 inhibitor that has been recently approved for the treatment of type 2 diabetes mellitus. We describe a novel bioanalytical method using high-performance liquid chromatography (HPLC) coupled with fluorescence detection for quantitative determination of ERTU in rat plasma. Acetonitrile-based protein precipitation method was used for sample preparation, and chromatographic separation was performed on a Kinetex® C18 column with an isocratic mobile phase comprising acetonitrile and 10 mM potassium phosphate buffer (pH 6.0). The eluent was monitored by a fluorescence detector at an optimized excitation/emission wavelength pair of 277/320 nm. The method was validated to demonstrate the selectivity, linearity (ranging from 4 to 2000 ng/mL), precision, accuracy, recovery, matrix effect, and stability in line with the current FDA guidelines. The newly developed method was successfully applied to investigate the pharmacokinetic interactions of ERTU with mefenamic acid (MEF) and ketoconazole (KET). The findings of the present study revealed that the pharmacokinetics of ERTU may be altered by concurrent administration of MEF and KET in rats. To our knowledge, the present study is the first to develop a validated bioanalytical method for quantification of ERTU using HPLC coupled with fluorescence detection and to assess the drug interaction potential of ERTU with non-steroidal anti-inflammatory (MEF) and azole antifungal (KET) drugs.

Abstract
Ertugliflozin, a sodium-glucose cotransporter 2 inhibitor for the treatment of type 2 diabetes mellitus, prevents renal glucose reabsorption resulting in urinary glucose excretion. This open-label, parallel cohort, randomized study conducted in healthy Chinese adults residing in China assessed the pharmacokinetics, tolerability, and safety of 5 mg and 15 mg of ertugliflozin following single (fasted condition) and multiple-dose (fed condition) administration. Sixteen subjects were randomized and completed the study. Ertugliflozin absorption was rapid, with maximum plasma concentrations observed 1 hour after dosing under fasted conditions and 2 to 4 hours after dosing under fed conditions. Following single- and multiple-dose administration, ertugliflozin exhibited dose-proportional exposures with an apparent mean terminal half-life of approximately 9.5 to 11.9 hours. Steady state was reached after 4 once-daily doses. The accumulation ratio based on the area under the plasma concentration-time curve after multiple-dose administration was approximately 1.3 and 1.2 for ertugliflozin 5 mg and 15 mg, respectively. Ertugliflozin was generally well tolerated following administration of single and multiple oral doses of 5 mg and 15 mg in healthy Chinese subjects. Pharmacokinetic comparison with non-Asian subjects indicated that there are no clinically meaningful racial differences and no dose modification of ertugliflozin is required based on race or body weight.

Abstract
Ertugliflozin, a sodium-glucose cotransporter 2 inhibitor for the treatment of adults with type 2 diabetes mellitus, is expected to be coadministered with sitagliptin, metformin, glimepiride, and/or simvastatin. Four separate open-label, randomized, single-dose, crossover studies were conducted in healthy adults to assess the potential pharmacokinetic interactions between ertugliflozin 15 mg and sitagliptin 100 mg (n = 12), metformin 1000 mg (n = 18), glimepiride 1 mg (n = 18), or simvastatin 40 mg (n = 18). Noncompartmental pharmacokinetic parameters derived from plasma concentration-time data were analyzed using mixed-effects models to assess interactions. Coadministration of sitagliptin, metformin, glimepiride, or simvastatin with ertugliflozin had no effect on area under the plasma concentration-time profile from time 0 to infinity (AUCinf ) or maximum observed plasma concentration (Cmax ) of ertugliflozin (per standard bioequivalence boundaries, 80% to 125%). Similarly, ertugliflozin did not have any impact on AUCinf or Cmax of sitagliptin, metformin, or glimepiride. AUCinf for simvastatin (24%) and simvastatin acid (30%) increased slightly after coadministration with ertugliflozin and was not considered clinically relevant. All treatments were well tolerated. The lack of clinically meaningful pharmacokinetic interactions demonstrates that ertugliflozin can be coadministered safely with sitagliptin, metformin, glimepiride, or simvastatin without any need for dose adjustment.

Abstract
INTRODUCTION Type 2 diabetes mellitus (T2DM) is a growing and serious global health problem. Inhibition of the sodium--glucosecotransporter-2 (SGLT2) can increase urinary glucose excretion and decrease plasma glucose levels in an insulin-independent manner. Ertugliflozin is a highly selective inhibitor of SGLT2, and was approved in the US for the treatment of adults with T2DM. Areas covered: In this paper, the mechanism of action, pharmacokinetics, clinical efficacy, safety, etc., of ertugliflozin have been introduced. Expert commentary: Ertugliflozin offers a novel, therapeutic approach to T2DM. Advantages of ertugliflozin include reduction in glycated hemoglobin, weight loss and blood pressure lowering with a low risk of hypoglycemia. The main adverse effects likely to be seen are genital fungal infections. Studies show that there is no increased risk of cardiovascular disease, but studies focusing on longer duration outcome are still essential.

Abstract
Ertugliflozin, a sodium glucose cotransporter‐2 inhibitor, is approved in the United States for treatment of type 2 diabetes mellitus. A novel two‐period study design with 14C microtracer dosing in each period was used to determine absolute oral bioavailability (F) and fraction absorbed (Fa) of ertugliflozin. Eight healthy adult men received 100‐μg i.v. 14C‐ertugliflozin (400 nCi) dose 1 h after a 15‐mg oral unlabeled ertugliflozin dose (period 1), followed by 100 μg 14C‐ertugliflozin orally along with 15 mg oral unlabeled ertugliflozin (period 2). Unlabeled ertugliflozin plasma concentrations were determined using high‐performance liquid‐chromatography tandem mass spectrometry (HPLC‐MS/MS). 14C‐ertugliflozin plasma concentrations were determined using HPLC‐accelerator mass spectrometry (AMS) and 14C urine concentrations were determined using AMS. F ((area under the curve (AUC)p.o./14C‐AUCi.v.)*(14C‐Dosei.v./Dosep.o.)) and Fa ((14C_Total_Urinep.o./14C_Total_Urinei.v.)* (14C‐Dosei.v./14C‐Dosep.o.)) were estimated. Estimates of F and Fa were 105% and 111%, respectively. Oral absorption of ertugliflozin was complete under fasted conditions and F was ∼100%. Ertugliflozin was well tolerated.

Abstract
INTRODUCTION Ertugliflozin is a sodium-glucose cotransporter 2 inhibitor in development for type 2 diabetes mellitus (T2DM). The safety and efficacy of ertugliflozin were evaluated over 52 weeks in patients with chronic kidney disease (CKD). METHODS In this double-blind randomized study (NCT01986855), patients with glycated hemoglobin (A1C) 7.0-10.5% and stage 3 CKD [estimated glomerular filtration rate (eGFR) ≥ 30 to < 60 mL/min/1.73 m2] who were undergoing treatment with standard diabetes therapy (or therapies) including insulin and/or sulfonylureas were randomized to once-daily ertugliflozin 5 mg, 15 mg, or placebo. Patients on metformin underwent a pre-randomization ≥ 10-week wash-off period. The primary endpoint was change from baseline in A1C at week 26 in the overall cohort. Secondary efficacy endpoints were assessed in the stage 3A CKD cohort (eGFR ≥ 45 to < 60 mL/min/1.73 m2) at weeks 26 and 52. Safety was assessed in the overall cohort. RESULTS 468 patients were randomized (baseline mean A1C 8.2%). At week 26, reductions from baseline in A1C were observed across groups in the overall cohort [least squares mean changes (95% confidence interval) - 0.3% (- 0.4, - 0.1), - 0.3% (- 0.4, - 0.1), and - 0.4% (- 0.6, - 0.3) for placebo and for ertugliflozin 5 mg and 15 mg, respectively]. Prohibited use of metformin was identified in ~ 17% of patients and impacted evaluation of the primary endpoint. Greater reductions from baseline in body weight, fasting plasma glucose, and systolic blood pressure were observed with ertugliflozin versus placebo at week 26 (stage 3A CKD cohort). The incidences of urinary tract infections, genital mycotic infections, and hypoglycemia adverse events were not meaningfully different between groups. The incidence of hypovolemia-related adverse events was higher with ertugliflozin relative to placebo. CONCLUSION Although surreptitious metformin use impacted the primary analysis, reductions in blood glucose and body weight were observed with ertugliflozin in patients with T2DM and stage 3 CKD; ertugliflozin had an acceptable safety profile.
