Abstract
BACKGROUND Angiopoietin-like protein 3 (ANGPTL3) is a novel therapeutic target for hyperlipidemia. Vupanorsen, an antisense oligonucleotide targeting ANGPTL3, reduced triglycerides up to 57% in a phase 2b trial, but caused dose-dependent increases in hepatic fat fraction (HFF). OBJECTIVE To determine the degree of HFF progression with escalating doses of vupanorsen, differential HFF increases in key patient subgroups, and the correlation between changes in HFF and liver enzymes. METHODS TRANSLATE-TIMI 70 was a randomized, placebo-controlled trial testing 7 dosing regimens of vupanorsen in 286 adults with hyperlipidemia. A total of 227 patients had HFF measured at baseline and 24 weeks and were included in this analysis. RESULTS The median HFF at baseline was 8.5%. Vupanorsen led to dose-dependent relative increases in HFF of up to 76% at 24 weeks (p < 0.001), corresponding to an absolute increase of up to 7.0% at the highest dose (p < 0.001). Increases in HFF were numerically greater in patients who had elevated baseline HFF, body mass index, triglycerides, or diabetes. Vupanorsen also increased liver enzymes in a dose-dependent manner, and changes in HFF were moderately positively correlated with changes in aspartate transaminase (AST) (rho = 0.49, p < 0.001) and alanine transaminase (ALT) (rho = 0.50, p < 0.001). CONCLUSION Vupanorsen, an inhibitor of ANGPTL3 protein synthesis, caused dose-dependent increases in HFF. Increases in HFF were only moderately correlated with elevations in AST and ALT, suggesting that liver enzymes are an imperfect indicator to detect increases in hepatic fat. These results highlight the need to monitor HFF in clinical trials of therapies targeting intracellular ANGPTL3 inhibition, especially those that are targeted to the liver.

Abstract
Vupanorsen (PF-07285557) is a second-generation ligand-conjugated 2'O-methoxyethyl modified antisense oligonucleotide designed to target angiopoietin-like 3 (ANGPTL3) mRNA expressed by the liver, shown to reduce lipids and apolipoproteins in subjects with dyslipidemia. Using pooled data from two phase I studies of participants with elevated triglycerides (Western: n = 48 and Japanese: n = 12), and two phase II studies of patients with hypertriglyceridemia, diabetes, and nonalcoholic fatty liver disease (n = 105), and statin-treated patients with dyslipidemia (n = 286), we developed population pharmacokinetic (PK) and PK/pharmacodynamic (PK/PD) models. Efficacy target values were set a priori to -75%, -60%, and -35% for ANGPTL3, triglyceride (TG), and non-high-density lipoprotein-cholesterol (non-HDL-C), respectively. Covariates evaluated via a full model approach included baseline body weight, age, estimated glomerular filtration rate (eGFR), anti-drug antibody (ADA) status, sex, and race. Vupanorsen population PK was well-characterized by a two-compartment model with first-order absorption and elimination. Apparent clearance (CL/F) for ADA-positive, female, and Asian participants was estimated to be about 62% (relative standard error 12%), 18% (9%), and 30% (20%) lower than ADA-negative, male, and non-Asian participants, respectively. The associations between CL/F and Black race, age, and eGFR were negligible. The developed population PK/PD model was robust to predict the dose-response relationships. The model predicted that ANGPTL3 target reduction of 75% can be sufficiently achieved with a 320-mg monthly dose of vupanorsen, but target values for TG and non-HDL-C were not expected to be achieved at doses up to 320 mg monthly in patients with dyslipidemia.

Abstract
Vupanorsen (PF-07285557) is a second-generation tri-N-acetyl galactosamine (GalNAc3 )-antisense oligonucleotide targeted to angiopoietin-like 3 (ANGPTL3) mRNA, shown to reduce lipids and apolipoproteins in subjects with dyslipidemia. To aid bringing innovative drugs to global patients efficiently, a multi-purpose Japanese phase I study was conducted, with integrated development approaches agreed by the Pharmaceuticals and Medical Devices Agency (PMDA). This randomized, double-blind, placebo-controlled, single-ascending dose (SAD) study investigated the safety, tolerability, pharmacokinetics, and pharmacodynamics of vupanorsen administered subcutaneously to Japanese adults (20-65 years) with elevated triglycerides (TG). Participants were randomized (1:1:1) to vupanorsen (80:160 mg) or placebo (N = 4 each). Vupanorsen 160 mg was a first-in-human (FIH) dose level. Vupanorsen was well-tolerated with no treatment-related adverse events reported for either dose. Absorption into the systemic circulation was rapid with median time to maximum concentration (Tmax ) of 3.5 and 2.0 h, for vupanorsen 80 and 160 mg, respectively. Following maximum concentration (Cmax ), vupanorsen underwent multiphasic decline characterized by a relatively fast initial distribution phase followed by slower terminal elimination phase, with elimination half-life (t1/2 ) of 397 and 499 h (80, 160 mg), respectively. Area under the concentration-time curve (AUC) and Cmax increased in a greater than dose-proportional manner. Pharmacodynamic markers (ANGPTL3, TG, and other key lipids) were reduced with vupanorsen versus placebo. Vupanorsen was safe and well-tolerated in healthy Japanese participants with elevated TG. This study provided FIH data for vupanorsen 160 mg. Moreover, the SAD study in Japanese participants fulfilled PMDA bridging requirements, and with the totality of global vupanorsen data, supported the PMDA waiver for a local phase II dose-finding study. ClinicalTrials.gov: NCT04459767.

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
Importance Sodium-glucose cotransporter 2 (SGLT2) inhibitors favorably affect cardiovascular (CV) and kidney outcomes; however, the consistency of outcomes across the class remains uncertain. Objective To perform meta-analyses that assess the CV and kidney outcomes of all 4 available SGLT2 inhibitors in patients with type 2 diabetes. Data Sources A systematic literature search was conducted in PubMed from January 1, 2015, to January 31, 2020. Study Selection One hundred forty-five records were initially identified; 137 were excluded because of study design or topic of interest. As a result, a total of 6 randomized, placebo-controlled CV and kidney outcomes trials of SGLT2 inhibitors in patients with type 2 diabetes were identified, with contributory data from 9 publications. All analyses were conducted on the total patient population of these trials. Data Extraction and Synthesis Standardized data search and abstraction were performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) Statement. Data were analyzed using a fixed-effect model. Main Outcomes and Measures Outcomes included time to the first event of (1) the composite of major adverse CV events of myocardial infarction, stroke, or CV death, and each component, (2) the composite of hospitalization for heart failure (HHF) or CV death (HHF/CV death) and each component, and (3) kidney composite outcomes. For outcomes in the overall trial populations and in selected subgroups, hazard ratios (HRs) and 95% CIs were pooled and meta-analyzed across trials. Results Data from 6 trials comprised 46 969 unique patients with type 2 diabetes, including 31 116 (66.2%) with atherosclerotic CV disease. The mean (SD) age of all trial participants was 63.7 (7.9) years; 30 939 (65.9%) were men, and 36 849 (78.5%) were White. The median number of participants per trial was 8246 (range, 4401-17 160). Overall, SGLT2 inhibitors were associated with a reduced risk of major adverse CV events (HR, 0.90; 95% CI, 0.85-0.95; Q statistic, P = .27), HHF/CV death (HR, 0.78; 95% CI, 0.73-0.84; Q statistic, P = .09), and kidney outcomes (HR, 0.62; 95% CI, 0.56-0.70; Q statistic, P = .09), with no significant heterogeneity of associations with outcome. Associated risk reduction for HHF was consistent across the trials (HR, 0.68; 95% CI, 0.61-0.76; I2 = 0.0%), whereas significant heterogeneity of associations with outcome was observed for CV death (HR, 0.85; 95% CI, 0.78-0.93; Q statistic, P = .02; I2 = 64.3%). The presence or absence of atherosclerotic CV disease did not modify the association with outcomes for major adverse CV events (HR, 0.89; 95% CI, 0.84-0.95 and HR, 0.94; 95% CI, 0.83-1.07, respectively; P = .63 for interaction), with similar absence of associations with outcome modification by prevalent atherosclerotic CV disease for HHF/CV death (P = .62 for interaction), HHF (P = .26 for interaction), or kidney outcomes (P = .73 for interaction). Conclusions and Relevance In this meta-analysis, SGLT2 inhibitors were associated with a reduced risk of major adverse CV events; in addition, results suggest significant heterogeneity in associations with CV death. The largest benefit across the class was for an associated reduction in risk for HHF and kidney outcomes, with benefits for HHF risk being the most consistent observation across the trials.

Abstract
AIM To assess the efficacy and safety of ertugliflozin in older patients with type 2 diabetes (T2D). MATERIALS AND METHODS This is a post hoc analysis of patients with T2D aged less than 65 years and those aged 65 years or older who participated in randomized, double-blind, phase III studies of ertugliflozin. Efficacy was evaluated in a pooled analysis of three placebo-controlled studies (ertugliflozin monotherapy and add-on therapy). Safety was evaluated in a pooled analysis of seven placebo- and active-controlled studies (including those used for efficacy). Least-squares mean change from baseline was calculated for HbA1c, fasting plasma glucose (FPG), body weight (BW) and systolic blood pressure (SBP). Safety evaluation included overall and prespecified adverse events (AEs). RESULTS In participants aged less than 65 years, the placebo-adjusted mean changes from baseline in HbA1c, BW and SBP with ertugliflozin 5 and 15 mg at week 26 were -0.9% and -1.0%, -1.9 and -1.8 kg, and -3.7 and -3.6 mmHg, respectively; in participants aged 65 years or older they were -0.6% and -0.8%, -1.9 and -2.2 kg, and -2.7 and -3.4 mmHg, respectively. The incidences of AEs, serious AEs, discontinuations and deaths in participants aged less than 65 years and those aged 65 years or older were generally similar across the treatment groups. In patients aged 65 years or older the incidences of volume depletion AEs and genital mycotic infection were higher with ertugliflozin than with non-ertugliflozin. CONCLUSIONS Ertugliflozin improved glycaemic control, BW and SBP in younger and older individuals with T2D and was generally well tolerated in both groups.

Abstract
BACKGROUND The cardiovascular effects of ertugliflozin, an inhibitor of sodium-glucose cotransporter 2, have not been established. METHODS In a multicenter, double-blind trial, we randomly assigned patients with type 2 diabetes and atherosclerotic cardiovascular disease to receive 5 mg or 15 mg of ertugliflozin or placebo once daily. With the data from the two ertugliflozin dose groups pooled for analysis, the primary objective was to show the noninferiority of ertugliflozin to placebo with respect to the primary outcome, major adverse cardiovascular events (a composite of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke). The noninferiority margin was 1.3 (upper boundary of a 95.6% confidence interval for the hazard ratio [ertugliflozin vs. placebo] for major adverse cardiovascular events). The first key secondary outcome was a composite of death from cardiovascular causes or hospitalization for heart failure. RESULTS A total of 8246 patients underwent randomization and were followed for a mean of 3.5 years. Among 8238 patients who received at least one dose of ertugliflozin or placebo, a major adverse cardiovascular event occurred in 653 of 5493 patients (11.9%) in the ertugliflozin group and in 327 of 2745 patients (11.9%) in the placebo group (hazard ratio, 0.97; 95.6% confidence interval [CI], 0.85 to 1.11; P<0.001 for noninferiority). Death from cardiovascular causes or hospitalization for heart failure occurred in 444 of 5499 patients (8.1%) in the ertugliflozin group and in 250 of 2747 patients (9.1%) in the placebo group (hazard ratio, 0.88; 95.8% CI, 0.75 to 1.03; P = 0.11 for superiority). The hazard ratio for death from cardiovascular causes was 0.92 (95.8% CI, 0.77 to 1.11), and the hazard ratio for death from renal causes, renal replacement therapy, or doubling of the serum creatinine level was 0.81 (95.8% CI, 0.63 to 1.04). Amputations were performed in 54 patients (2.0%) who received the 5-mg dose of ertugliflozin and in 57 patients (2.1%) who received the 15-mg dose, as compared with 45 patients (1.6%) who received placebo. CONCLUSIONS Among patients with type 2 diabetes and atherosclerotic cardiovascular disease, ertugliflozin was noninferior to placebo with respect to major adverse cardiovascular events.

Abstract
Supplemental Digital Content is available in the text. Background: In patients with type 2 diabetes mellitus, sodium-glucose cotransporter 2 inhibitors reduce the risk of hospitalization for heart failure (HHF). We assessed the effect of ertugliflozin on HHF and related outcomes. Methods: VERTIS CV (Evaluation of Ertugliflozin Efficacy and Safety Cardiovascular Outcomes Trial), a double-blind, placebo-controlled trial, randomly assigned patients with type 2 diabetes mellitus and atherosclerotic cardiovascular (CV) disease to once-daily ertugliflozin 5 mg, 15 mg, or placebo. Prespecified secondary analyses compared ertugliflozin (pooled doses) versus placebo on time to first event of HHF and composite of HHF/CV death, overall and stratified by prespecified characteristics. Cox proportional hazards modeling was used with the Fine and Gray method to account for competing mortality risk, and Andersen-Gill modeling to analyze total (first+recurrent) HHF and total HHF/CV death events. Results: A total of 8246 patients were randomly assigned to ertugliflozin (n=5499) or placebo (n=2747); n=1958 (23.7%) had a history of heart failure (HF) and n=5006 (60.7%) had pretrial ejection fraction (EF) available, including n=959 with EF ≤45%. Ertugliflozin did not significantly reduce first HHF/CV death (hazard ratio [HR], 0.88 [95% CI, 0.75–1.03]). Overall, ertugliflozin reduced risk for first HHF (HR, 0.70 [95% CI, 0.54–0.90]; P=0.006). Previous HF did not modify this effect (HF: HR, 0.63 [95% CI, 0.44–0.90]; no HF: HR, 0.79 [95% CI, 0.54–1.15]; P interaction=0.40). In patients with HF, the risk reduction for first HHF was similar for those with reduced EF ≤45% versus preserved EF >45% or unknown. However, in the overall population, the risk reduction tended to be greater for those with EF ≤45% (HR, 0.48 [95% CI, 0.30–0.76]) versus EF >45% (HR, 0.86 [95% CI, 0.58–1.29]). Effect on risk for first HHF was consistent across most subgroups, but greater benefit of ertugliflozin was observed in 3 populations: baseline estimated glomerular filtration rate <60 mL·min–1·1.73 m–2, albuminuria, and diuretic use (each P interaction <0.05). Ertugliflozin reduced total events of HHF (rate ratio, 0.70 [95% CI, 0.56–0.87]) and total HHF/CV death (rate ratio, 0.83 [95% CI, 0.72–0.96]). Conclusions: In patients with type 2 diabetes mellitus, ertugliflozin reduced the risk for first and total HHF and total HHF/CV death, adding further support for the use of sodium-glucose cotransporter 2 inhibitors in primary and secondary prevention of HHF.

Abstract
INTRODUCTION This post hoc exploratory analysis examined the effects of ertugliflozin on liver enzymes in patients with type 2 diabetes mellitus (T2DM). METHODS Data were pooled from seven randomized, double-blind VERTIS phase 3 trials that evaluated ertugliflozin (5 mg and 15 mg) versus non-ertugliflozin (placebo, glimepiride, or sitagliptin) treatment in patients with T2DM. Change from baseline at week 52 of treatment in alanine and aspartate aminotransferase (ALT and AST, respectively) serum levels (overall and categorized into tertiles by baseline ALT and AST), Fibrosis-4 Index (FIB-4), glycated hemoglobin (HbA1c), and body weight were evaluated, along with the association between changes in ALT and AST and changes in HbA1c and body weight by treatment. RESULTS Baseline characteristics were balanced across treatment groups (ertugliflozin 5 mg, n = 1716; ertugliflozin 15 mg, n = 1693; non-ertugliflozin, n = 1450). At week 52 of treatment, serum levels of ALT and AST were reduced in patients in the ertugliflozin treatment groups (5 and 15 mg, respectively) compared with those in the non-ertugliflozin group. The comparator-adjusted mean (95% confidence interval [CI]) difference in change from baseline at week 52 for ALT was - 3.35 (- 4.40, - 2.31) IU/L for ertugliflozin 5 mg and - 4.08 (- 5.13, - 3.03) IU/L for ertugliflozin 15 mg; for AST, the respective values were - 1.81 (- 2.50, - 1.11) IU/L and - 2.12 (- 2.82, - 1.42) IU/L. The effects of ertugliflozin were detected across all baseline ALT and AST tertiles, with the highest tertile showing the greatest treatment differences. No meaningful differences were observed between treatment groups for FIB-4. Changes in ALT and AST showed a weak but statistically significant association with changes in HbA1c and body weight in all treatment groups. CONCLUSIONS Treatment with ertugliflozin resulted in a reduction in the levels of hepatic transaminases compared with the non-ertugliflozin group after 52 weeks of treatment. Changes in body weight and HbA1c contributed at least in part to the effects of ertugliflozin on liver enzymes.

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
Objective: To assess the efficacy and safety of ertugliflozin in Hispanic/Latino patients with type 2 diabetes (T2DM).Methods: Analysis of data from Hispanic/Latino patients who participated in randomized, double-blind phase III studies. Ertugliflozin efficacy was evaluated when initiated as a single agent (as monotherapy or add-on therapy) and when initiated in combination with sitagliptin. Least-squares mean change from baseline was calculated for glycated hemoglobin (HbA1c), body weight (BW), and systolic blood pressure (SBP). Safety evaluation included overall and prespecified adverse events (AEs).Results: Analyses included 1178 Hispanic/Latino patients. In a pooled analysis of three placebo-controlled studies where ertugliflozin was initiated as a single agent, the placebo-corrected change from baseline in HbA1c at week 26 for ertugliflozin 5 and 15 mg was -0.8 and -1.0%, respectively. In an active-comparator study, when initiated as a single agent, the change from baseline in HbA1c at week 52 was -0.5, -0.7, and -0.5% for ertugliflozin 5 mg, ertugliflozin 15 mg, and glimepiride, respectively. In a placebo-controlled study, when initiated in combination with sitagliptin, the placebo-corrected change from baseline in HbA1c at week 26 for ertugliflozin 5 mg/sitagliptin and ertugliflozin 15 mg/sitagliptin was -1.3 and -1.6%, respectively. In an active-comparator study, when initiated in combination with sitagliptin, the change from baseline in HbA1c at week 26 was -1.4, -1.6, and -0.9 for ertugliflozin 5 mg/sitagliptin, ertugliflozin 15 mg/sitagliptin, and sitagliptin alone, respectively. Reductions in BW and SBP were observed with ertugliflozin as a single agent or combined with sitagliptin. The incidences of overall and prespecified AEs in Hispanic/Latino patients were generally consistent with the known safety profile of ertugliflozin.Conclusion: Ertugliflozin, administered as a single agent or as a combination with sitagliptin, improved HbA1c, BW, and SBP. Ertugliflozin was generally well-tolerated in Hispanic/Latino patients with T2DM.

Abstract
AIMS/HYPOTHESIS This study aimed to evaluate the effect of ertugliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor, on eGFR and albuminuria (urine albumin/creatinine ratio [UACR]) vs glimepiride or placebo/glimepiride (non-ertugliflozin) over 104 weeks of treatment in participants with type 2 diabetes mellitus, using pooled data from two randomised controlled, active comparator studies from the eValuation of ERTugliflozin effIcacy and Safety (VERTIS) programme (Clinicaltrials.gov NCT01999218 [VERTIS SU] and NCT02033889 [VERTIS MET]). In the VERTIS SU study, ertugliflozin was evaluated vs glimepiride over 104 weeks. In the VERTIS MET study, ertugliflozin was evaluated vs placebo over 26 weeks; eligible participants were switched from placebo to blinded glimepiride from week 26 to week 104. The glycaemic efficacy of ertugliflozin vs non-ertugliflozin was also assessed in the pooled population. METHODS Post hoc, exploratory analysis was used to investigate mean changes from baseline in eGFR and UACR over 104 weeks. RESULTS Overall, mean (SD) baseline eGFR was 88.2 (18.8) ml min-1 (1.73 m)-2 and geometric mean (95% CI) of baseline UACR was 1.31 mg/mmol (1.23, 1.38). At week 6, the changes in eGFR from baseline were -2.3, -2.7 and -0.7 ml min-1 (1.73 m)-2 for the ertugliflozin 5 mg, ertugliflozin 15 mg and non-ertugliflozin groups, respectively. Mean eGFR in the ertugliflozin groups increased over time thereafter, while it decreased in the non-ertugliflozin group. Week 104 changes in eGFR from baseline were -0.2, 0.1 and -2.0 ml min-1 (1.73 m)-2 for the ertugliflozin 5 mg, ertugliflozin 15 mg and non-ertugliflozin groups, respectively. Among 415 patients (21.4% of the cohort) with albuminuria at baseline, the ertugliflozin groups had greater reductions in UACR at all measured time points up to week 104. At week 104, the non-ertugliflozin-corrected difference in UACR (95% CI) was -29.5% (-44.8, -9.8; p < 0.01) for ertugliflozin 5 mg and -37.6% (-51.8, -19.2; p < 0.001) for ertugliflozin 15 mg. Least squares mean changes from baseline in HbA1c (mmol/mol [95% CI]) at week 104 were similar between treatment groups: -6.84 (-7.64, -6.03), -7.74 (-8.54, -6.94) and -6.84 (-7.65, -6.03) in the ertugliflozin 5 mg, ertugliflozin 15 mg and non-ertugliflozin groups, respectively. Least squares mean changes from baseline in HbA1c (% [95% CI]) at week 104 were: -0.63 (-0.70, -0.55), -0.71 (-0.78, -0.64) and -0.63 (-0.70, -0.55) in the ertugliflozin 5 mg, ertugliflozin 15 mg and non-ertugliflozin groups, respectively. CONCLUSIONS/INTERPRETATION Ertugliflozin reduced eGFR at week 6, consistent with the known pharmacodynamic effects of SGLT2 inhibitors on renal function. Over 104 weeks, eGFR values returned to baseline and were higher with ertugliflozin compared with non-ertugliflozin treatment, even though changes in HbA1c did not differ between the groups. Ertugliflozin reduced UACR in patients with baseline albuminuria. TRIAL REGISTRATION clinicaltrials.gov NCT01999218 and NCT02033889.

Abstract
INTRODUCTION The sodium-glucose cotransporter 2 (SGLT2) inhibitor ertugliflozin is approved for the treatment of adults with type 2 diabetes mellitus (T2DM). This analysis was conducted on safety data pooled from phase 3 studies using ertugliflozin 5 mg or 15 mg versus placebo or an active comparator. METHODS The placebo pool (n = 1544) comprised data from three similarly designed 26-week placebo-controlled studies. The broad pool (n = 4849) comprised these three placebo-controlled studies plus four placebo- or active-controlled studies with treatment durations of up to 104 weeks. RESULTS In the placebo pool, there were no notable differences across groups in the incidence of adverse events (AEs), serious AEs, or AEs resulting in discontinuation from study medication, while associations were observed with genital mycotic infection in both females (3.0%, 9.1%, and 12.2% in the placebo, ertugliflozin 5 mg, and ertugliflozin 15 mg groups, respectively) and males (0.4%, 3.7%, 4.2%), thirst (0.2%, 1.3%, 1.0%), and increased urination (1.0%, 2.7%, 2.4%). In the broad pool, volume depletion was increased with ertugliflozin in patients with estimated glomerular filtration rate < 60 ml/min/1.73 m2, aged ≥ 65 years, or who were taking diuretics. Ertugliflozin was not associated with increased urinary tract infection, fracture, hypoglycemia, pancreatitis, renal or hepatic injury, hypersensitivity, malignancy, or venous thromboembolism. Small numbers of patients were reported with lower limb amputation [0.1% (non-ertugliflozin group), 0.2% (ertugliflozin 5 mg), 0.5% (ertugliflozin 15 mg)]. There were three cases of ketoacidosis (all ertugliflozin 15 mg) and no cases of Fournier's gangrene. CONCLUSION This pooled analysis showed that ertugliflozin was generally well tolerated in a large population of patients with T2DM with and without moderate renal impairment who were taking a range of background diabetes medications including insulin and insulin secretagogs, with results that are generally consistent with those for other SGLT2 inhibitors.

Abstract
OBJECTIVE This study aimed to evaluate ertugliflozin in patients with overweight and obesity with type 2 diabetes mellitus. METHODS Data from three placebo-controlled, randomized, Phase 3 studies were pooled. Patients with baseline BMI ≥ 25 (1,377/1,544; 89%) were assessed with a stratification by BMI subgroup. RESULTS At week 26, reductions from baseline in glycated hemoglobin A1c (HbA1c), fasting plasma glucose, body weight (BW), and systolic blood pressure (SBP) were greater with ertugliflozin versus placebo. For placebo, ertugliflozin 5 mg, and ertugliflozin 15 mg, respectively, least squares mean change was 0.1%, -0.8%, and -0.9% for HbA1c and -1.2 kg, -3.1 kg, and -3.2 kg for BW. HbA1c reductions were consistent across BMI subgroups. For ertugliflozin 5 mg and 15 mg, least squares mean change (placebo adjusted) in absolute BW was -1.4 kg and -1.2 kg for BMI 25 to < 30, -1.8 kg and -1.9 kg for BMI 30 to < 35, and -2.5 kg and -2.9 kg for BMI ≥ 35. Percent BW changes were similar across BMI subgroups. Incidence of adverse events was 52.5%, 44.6%, and 50.1% with placebo, ertugliflozin 5 mg, and ertugliflozin 15 mg, respectively. CONCLUSIONS Meaningful reductions in HbA1c, fasting plasma glucose, BW, and SBP were observed with ertugliflozin in patients with overweight and obesity with type 2 diabetes mellitus. Ertugliflozin improved HbA1c and SBP and reduced BW across BMI subgroups. Ertugliflozin was generally well tolerated.

Abstract
AIM Post-hoc analysis of the efficacy and safety of ertugliflozin in East/Southeast (E/SE) Asian patients with type 2 diabetes mellitus (T2DM). MATERIALS AND METHODS Efficacy evaluations used data from randomized, double-blind, phase 3 studies: a pool of two 26-week placebo-controlled studies and one 52-week active-comparator (glimepiride) study. Least squares mean change from baseline was calculated for HbA1c, fasting plasma glucose (FPG), body weight (BW) and systolic blood pressure (SBP). Safety evaluation included overall and prespecified adverse events based on pooled data (broad pool) from seven phase 3 studies (including studies in the efficacy analysis). RESULTS Among 161 E/SE Asian patients in the placebo pool (ertugliflozin, n = 106), ertugliflozin reduced HbA1c, FPG, BW and SBP from baseline at week 26. The placebo-adjusted changes from baseline for ertugliflozin 5 and 15 mg were: HbA1c, -0.9% and -1.0%; BW, -2.1 and -1.9 kg; and SBP, -3.3 and -3.5 mmHg, respectively. Among 174 E/SE Asian patients in the active-comparator study (ertugliflozin, n = 118), HbA1c changes from baseline at week 52 were -0.6%, -0.6% and -0.7% for ertugliflozin 5 mg, 15 mg and glimepiride, respectively. Ertugliflozin 5 and 15 mg reduced BW from baseline by -4.3 and -4.1 kg, respectively, and SBP by -7.4 and -9.3 mmHg, respectively, compared with glimepiride. Safety findings were generally consistent with overall ertugliflozin safety data published to date. CONCLUSIONS Treatment with ertugliflozin was associated with reductions in HbA1c, FPG, BW and SBP, and was generally well tolerated in E/SE Asian patients with T2DM.

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
BACKGROUND This pooled analysis assessed the efficacy of ertugliflozin versus placebo as monotherapy or with other antihyperglycaemic agents across patient subgroups defined by demographic and disease characteristics. METHODS Data from three phase III randomised, placebo-controlled, double-blind studies (NCT01958671, NCT02033889 and NCT02036515) with similar designs and populations were pooled (N = 1544). RESULTS At Week 26, placebo-adjusted least squares mean changes from baseline in glycated haemoglobin with ertugliflozin 5 and 15 mg were -0.8% (95% confidence interval: -0.9, -0.7) and -0.9% (-1.0, -0.8), respectively. Reductions were consistent across subgroups. Placebo-adjusted least squares mean changes in body weight were -1.8 kg (-2.2, -1.4) for both ertugliflozin doses; for systolic blood pressure, these were -3.4 mmHg (-4.8, -2.0) and -3.5 mmHg (-4.9, -2.0) for ertugliflozin 5 and 15 mg, respectively. Higher proportions of patients receiving ertugliflozin had glycated haemoglobin <7.0%, weight loss ⩾5% and systolic blood pressure <130 mmHg versus placebo. Ertugliflozin and placebo safety profiles were similar, including incidences of hypoglycaemia, urinary tract infection and hypovolaemia. Genital mycotic infection and adverse events related to osmotic diuresis were more common with ertugliflozin. CONCLUSION Ertugliflozin demonstrated efficacy as monotherapy or with other antihyperglycaemic agents in patients with different demographic and disease characteristics and was generally well tolerated.

Abstract
Objective: To assess the safety and efficacy of ertugliflozin over 104 weeks in patients with type 2 diabetes mellitus (T2DM) inadequately controlled on metformin. Methods: In this double-blind, multicenter, randomized, phase III study (VERTIS SU; NCT01999218), adults with T2DM and glycated hemoglobin (HbA1c) 7.0-9.0% on metformin ≥1500 mg/day received ertugliflozin 5 mg or 15 mg, or glimepiride. The primary efficacy time point was Week 52; double-blinded treatment continued until Week 104. Results: Baseline characteristics of randomized, treated patients (n = 1315) were similar across groups (mean age 58.2 years, HbA1c 7.8%); 76.4% completed the study; 61.6% completed on study medication. Mean glimepiride dose at 104 weeks was 3.5 mg/day. At Week 104, least squares mean change from baseline in HbA1c (95% confidence intervals) were -0.3% (-0.4, -0.2), -0.4% (-0.5, -0.3) and -0.4% (-0.5, -0.3) for ertugliflozin 5 mg, 15 mg, and glimepiride, respectively. Ertugliflozin provided sustained reductions in body weight and systolic blood pressure (SBP) over 104 weeks. The incidence of adverse events (AEs) and serious AEs was similar across groups. The incidence of symptomatic hypoglycemia was 3.8%, 6.4% and 22.1% in the ertugliflozin 5 mg, 15 mg, and glimepiride groups, respectively. Genital mycotic infections were reported in 5.3%, 2.6% and 0% of men, respectively, and 9.2%, 12.3% and 1.4% of women, respectively. The incidence of urinary tract infection and hypovolemia AEs was similar across groups. Conclusions: Ertugliflozin was well tolerated and provided clinically meaningful glycemic control and durable reductions in body weight and SBP over 104 weeks.

Abstract
A fixed‐dose combination (FDC) of ertugliflozin, a selective sodium‐glucose cotransporter 2 inhibitor, and immediate‐release metformin is approved for the treatment of type 2 diabetes mellitus in the United States and European Union. Four open‐label, randomized, 2‐period, single‐dose, crossover studies were conducted under fasted conditions in healthy subjects to demonstrate bioequivalence of the ertugliflozin/metformin FDC tablets and coadministration of the individual components at respective strengths. In each study, 32 or 34 subjects received an ertugliflozin/metformin FDC tablet (2.5 mg/500 mg, 7.5 mg/850 mg, or 7.5 mg/1000 mg) and the respective doses of individual components (ertugliflozin with US‐ or EU‐sourced metformin [Glucophage]). Plasma samples for ertugliflozin and metformin concentrations were collected for 72 hours in each period. For both ertugliflozin and metformin, the 90% confidence intervals for the adjusted geometric mean ratio (FDC : coadministration) for area under the plasma concentration–time profile from time zero extrapolated to infinity and maximum observed plasma concentration were within acceptance criteria for bioequivalence. The majority of adverse events were mild in intensity. The studies demonstrated that each strength of FDC tablet is bioequivalent to respective doses of coadministered individual components, supporting that safety and efficacy can be bridged to the individual components used in phase 3 studies evaluating ertugliflozin in combination with metformin.

Abstract
AIM Phase III, randomized, double-blind study evaluating the efficacy and safety of ertugliflozin in Asian patients with type 2 diabetes mellitus (T2DM) inadequately controlled on metformin, including evaluation in the China subpopulation. MATERIALS AND METHODS A 26-week, double-blind study of 506 Asian patients (80.2% from mainland China), randomized 1:1:1 to placebo, ertugliflozin 5- or 15 mg, was performed. Primary endpoint was change from baseline in HbA1c at week 26. Secondary endpoints were change from baseline at week 26 in fasting plasma glucose (FPG), body weight (BW), systolic/diastolic blood pressure (SBP/DBP), and proportion of patients with HbA1c <7.0%. Hypotheses for the primary endpoint and FPG and BW secondary endpoints were tested in the China subpopulation. RESULTS At week 26, least squares mean (95% CI) change from baseline HbA1c was significantly greater with ertugliflozin 5- and 15 mg versus placebo: -1.0% (-1.1, -0.9), -0.9% (-1.0, -0.8), -0.2% (-0.3, -0.1), respectively. Ertugliflozin significantly reduced FPG, BW and SBP. Reductions in DBP with ertugliflozin were not significant. At week 26, 16.2%, 38.2% and 40.8% of patients had HbA1c <7.0% with placebo, ertugliflozin 5- and 15 mg, respectively. 59.3%, 56.5% and 53.3% of patients experienced adverse events with placebo, ertugliflozin 5- and 15 mg, respectively. Incidence of symptomatic hypoglycaemia was higher for ertugliflozin 15 mg vs placebo. Results in the China subpopulation were consistent. CONCLUSIONS Ertugliflozin significantly improved glycaemic control and reduced BW and SBP in Asian patients with T2DM. Ertugliflozin was generally well-tolerated. Results in the China subpopulation were consistent with the overall population. ClinicalTrials.gov: NCT02630706.

Abstract
AIM To evaluate the long-term efficacy and safety of ertugliflozin in adults with type 2 diabetes mellitus inadequately controlled on metformin. MATERIALS AND METHODS A 104-week Phase III, randomized double-blind study with a 26-week placebo-controlled period (Phase A) and a 78-week period (Phase B) where blinded glimepiride was added to non-rescued placebo participants with fasting fingerstick glucose ≥6.1 mmol/L. Results through week 104 are reported. RESULTS Mean (standard error) change in HbA1c from baseline was -0.7% (0.07) and -1.0% (0.07) at week 52; -0.6% (0.08) and -0.9% (0.08) at week 104 for ertugliflozin 5 and 15 mg. At week 52, 34.8% and 36.6% participants had HbA1c <7.0%, and 24.6% and 33.7% at week 104, for ertugliflozin 5 and 15 mg. Ertugliflozin reduced fasting plasma glucose (FPG), body weight and systolic blood pressure (SBP) from baseline through week 104. The incidence of female genital mycotic infections (GMIs) was higher with ertugliflozin, and symptomatic hypoglycaemia was lower for ertugliflozin versus placebo/glimepiride. Minimal bone mineral density (BMD) changes were observed, similar to placebo/glimepiride, except at total hip where reduction in BMD was greater with ertugliflozin 15 mg versus placebo/glimepiride: difference in least squares means (95% CI) -0.50% (-0.95, -0.04) at week 52 and -0.84% (-1.44, -0.24) at week 104. CONCLUSIONS Ertugliflozin maintained improvements from baseline in HbA1c, FPG, body weight and SBP through week 104. Ertugliflozin was well tolerated, with non-clinically relevant changes in BMD. Compared with placebo/glimepiride, ertugliflozin increased female GMIs, but reduced the incidence of symptomatic hypoglycaemia. ClinicalTrials.gov Identifier: NCT02033889.

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
Ertugliflozin, an inhibitor of sodium‐glucose cotransporter 2, is approved in the United States and European Union for the treatment of type 2 diabetes in adults, both as monotherapy and as part of fixed‐dose combination (FDC) therapies with either sitagliptin or immediate‐release metformin. The effect of a standard, high‐fat breakfast on the pharmacokinetics of the highest strengths of ertugliflozin monotherapy (15 mg), ertugliflozin/sitagliptin FDC (15‐/100‐mg), and ertugliflozin/metformin FDC (7.5‐/1000‐mg) tablets was evaluated. In 3 separate open‐label, 2‐period, 2‐sequence, single‐dose, crossover studies, 14 healthy subjects per study were randomized to receive either ertugliflozin monotherapy or FDC tablets comprising ertugliflozin and sitagliptin or ertugliflozin and metformin under fasted and fed (or vice versa) conditions. Food did not meaningfully affect the pharmacokinetics of ertugliflozin, sitagliptin, or metformin. For FDCs, the effect of food was consistent with that described for individual components. All treatments were well tolerated. Ertugliflozin and ertugliflozin/sitagliptin FDC tablets can be administered without regard to meals. As metformin is administered with meals because of its gastrointestinal side effects, the ertugliflozin/metformin FDC should also be administered with meals.

Abstract
AIM This phase III, multicentre, randomized study (ClinicalTrials.gov; NCT01958671) evaluated the efficacy and safety of ertugliflozin monotherapy in adults with inadequately controlled type 2 diabetes (glycated haemoglobin [HbA1c], 7.0% to 10.5% [53-91 mmol/mol]) despite diet and exercise. MATERIALS AND METHODS The 52-week study comprised a 26-week, double-blind, placebo-controlled period (Phase A) during which 461 participants received placebo, ertugliflozin 5 mg/d or ertugliflozin 15 mg/d. This was followed by a 26-week active-controlled period (Phase B) during which participants in the placebo group who had not received glycaemic rescue therapy had blinded metformin added. Results to Week 52 are reported. Because of the use of metformin in Phase B, no statistical comparisons of efficacy were made between the ertugliflozin and placebo/metformin groups at Week 52. RESULTS The mean (standard error) change from baseline to Week 52 in HbA1c was -0.9% (0.1) and -1.0% (0.1) in the ertugliflozin 5 and 15 mg groups, respectively. The proportions of participants with HbA1c <7.0% at Week 52 were 25.6% and 28.5%, respectively. Ertugliflozin reduced fasting plasma glucose, body weight and systolic blood pressure (SBP). The incidence of genital mycotic infections (GMIs) in females was significantly higher in both ertugliflozin groups (5 mg, 26.9%; 15 mg, 29.0%) vs the placebo/metformin group (9.9%), and in males was significantly higher in the 15 mg group (7.8%) vs the placebo/metformin group (1.2%). Ertugliflozin was not associated with increased incidence of urinary tract infections, symptomatic hypoglycaemia or hypovolaemia adverse events compared with placebo/metformin. CONCLUSIONS Ertugliflozin treatment over 52 weeks improved glycaemic control and reduced body weight and SBP, but increased GMIs.

Abstract
AIM To evaluate the efficacy and safety of ertugliflozin and sitagliptin co-administration vs the individual agents in patients with type 2 diabetes who are inadequately controlled with metformin. METHODS In this study (Clinicaltrials.gov NCT02099110), patients with glycated haemoglobin (HbA1c) ≥7.5% and ≤11.0% (≥58 and ≤97 mmol/mol) with metformin ≥1500 mg/d (n = 1233) were randomized to ertugliflozin 5 (E5) or 15 (E15) mg/d, sitagliptin 100 mg/d (S100) or to co-administration of E5/S100 or E15/S100. The primary endpoint was change from baseline in HbA1c at Week 26. RESULTS At Week 26, least squares mean HbA1c reductions from baseline were greater with E5/S100 (-1.5%) and E15/S100 (-1.5%) than with individual agents (-1.0%, -1.1% and -1.1% for E5, E15 and S100, respectively; P < .001 for all comparisons). HbA1c <7.0% (<53 mmol/mol) was achieved by 26.4%, 31.9%, 32.8%, 52.3% and 49.2% of patients in the E5, E15, S100, E5/S100 and E15/S100 groups, respectively. Fasting plasma glucose reductions were significantly greater with E5/S100 and E15/S100 compared with individual agents. Body weight and systolic blood pressure (SBP) significantly decreased with E5/S100 and E15/S100 vs S100 alone. Glycaemic control, body weight and SBP effects of ertugliflozin were maintained to Week 52. Genital mycotic infections were more common among ertugliflozin-treated patients compared with those treated with S100. Incidences of symptomatic hypoglycaemia and adverse events related to hypovolaemia or urinary tract infection were similar among groups. CONCLUSIONS In patients with uncontrolled type 2 diabetes while using metformin, co-administration of ertugliflozin and sitagliptin provided more effective glycaemic control through 52 weeks compared with the individual agents.

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
AIMS To assess ertugliflozin in patients with type 2 diabetes who are inadequately controlled by metformin and sitagliptin. MATERIALS AND METHODS In this double-blind randomized study (Clinicaltrials.gov NCT02036515), patients (glycated haemoglobin [HbA1c] 7.0% to 10.5% [53-91 mmol/mol] receiving metformin ≥1500 mg/d and sitagliptin 100 mg/d; estimated glomerular filtration rate [eGFR] ≥60 mL/min/1.73 m2 ) were randomized to ertugliflozin 5 mg once-daily, 15 mg once-daily or placebo. The primary efficacy endpoint was change from baseline in HbA1c at Week 26; treatment was continued until Week 52. RESULTS A total of 464 patients were randomized (mean baseline HbA1c, 8.0% [64.3 mmol/mol]; eGFR, 87.9 mL/min/1.73 m2 ). After 26 weeks, placebo-adjusted least squares (LS) mean changes in HbA1c from baseline were -0.7% (-7.5 mmol/mol) and -0.8% (-8.3 mmol/mol) for ertugliflozin 5 and 15 mg, respectively (both P < .001); 17.0%, 32.1% and 39.9% of patients receiving placebo, ertugliflozin 5 mg or ertugliflozin 15 mg, respectively, had HbA1c <7.0% (53 mmol/mol). Significant reductions in fasting plasma glucose, body weight (BW) and systolic blood pressure (SBP) were observed with ertugliflozin relative to placebo. The positive effects of ertugliflozin on glycaemic control, BW and SBP were maintained through Week 52. A higher incidence of genital mycotic infections was observed in male and female patients receiving ertugliflozin (3.7%-14.1%) vs placebo (0%-1.9%) through Week 52. The incidence of urinary tract infections, symptomatic hypoglycaemia and hypovolaemia adverse events were not meaningfully different across groups. CONCLUSIONS Ertugliflozin added to metformin and sitagliptin was well-tolerated, and provided clinically meaningful, durable glycaemic control, BW and SBP reductions vs placebo over 52 weeks.

Abstract
AIM We evaluated the efficacy and safety of ertugliflozin, an SGLT2 inhibitor, in type 2 diabetes mellitus (T2DM) inadequately controlled (HbA1c, 7.0%-10.5%) with metformin monotherapy (≥1500 mg/d for ≥8 weeks). METHODS This was a double-blind, 26-week, multicentre study with ongoing 78-week extension (ClinicalTrials.gov identifier: NCT02033889). A total of 621 participants were randomized 1:1:1 to placebo, or ertugliflozin 5 or 15 mg/d. The primary endpoint was change from baseline at week 26 in HbA1c. Secondary efficacy endpoints were change from baseline at week 26 in fasting plasma glucose (FPG), body weight, systolic/diastolic blood pressure (SBP/DBP) and number of participants with HbA1c <7.0% (53 mmol/mol). Pre-specified adverse events (AEs) of special interest and percent change from baseline in bone mineral density (BMD) were also assessed at week 26. RESULTS At week 26, the placebo-adjusted least-squares mean change from baseline HbA1c (8.1%) was -0.7% and -0.9% for ertugliflozin 5 and 15 mg, respectively (both P < .001), to final means of 7.3% and 7.2%, respectively. The odds of HbA1c <7.0% were significantly greater in both ertugliflozin groups vs placebo. Ertugliflozin significantly reduced FPG, body weight, SBP and DBP vs placebo. The incidence of genital mycotic infections was higher in the ertugliflozin groups (female subjects: placebo, 0.9%; ertugliflozin 5 mg, 5.5%; ertugliflozin 15 mg, 6.3% [P = .032]; male subjects: 0%; 3.1%; 3.2%, respectively), as was the incidence of urinary tract infections and symptomatic hypoglycaemia. The incidence of hypovolaemia AEs was similar across groups. Ertugliflozin had no adverse impact on BMD at week 26. CONCLUSIONS Ertugliflozin added to metformin in patients with inadequately controlled T2DM improved glycaemic control, reduced body weight and BP, but increased the incidence of genital mycotic infections.

Abstract
INTRODUCTION This study assessed the safety and efficacy of ertugliflozin (an oral sodium-glucose cotransporter 2 inhibitor) vs. glimepiride in patients with type 2 diabetes mellitus (T2DM) inadequately controlled on metformin. METHODS This phase III, double-blind, non-inferiority study (NCT01999218) randomized patients with HbA1c ≥ 7.0% and ≤ 9.0% on stable metformin ≥ 1500 mg/day 1:1:1 to ertugliflozin 15 or 5 mg once-daily (QD), or glimepiride (titrated from 1 mg QD). The primary hypothesis was that ertugliflozin 15 mg was non-inferior to glimepiride on HbA1c (non-inferiority criterion: upper bound of the 95% confidence interval [CI] about the treatment difference < 0.3%). RESULTS Mean baseline HbA1c of randomized patients (N = 1326) was 7.8%. Mean and median doses of glimepiride were 3.0 mg/day throughout the study. At week 52, the least squares mean change (95% CI) from baseline in HbA1c was - 0.6% (- 0.7, - 0.5), - 0.6% (- 0.6, - 0.5), and - 0.7% (- 0.8, - 0.7) in the ertugliflozin 15 mg, ertugliflozin 5 mg, and glimepiride groups, respectively. The between-group difference for ertugliflozin 15 mg and glimepiride of 0.1% (- 0.0, 0.2) met the pre-specified non-inferiority criterion. Relative to glimepiride, greater body weight and systolic blood pressure (SBP) reductions were observed with ertugliflozin. The overall incidence of adverse events (AEs) was similar across groups. The incidence of symptomatic hypoglycemia and genital mycotic infection (GMI) were, respectively, lower and higher with ertugliflozin relative to glimepiride. The incidences of urinary tract infection and hypovolemia AEs were not meaningfully different among the groups. CONCLUSIONS Ertugliflozin 15 mg was non-inferior to glimepiride in reducing HbA1c when added to metformin in patients with T2DM. Ertugliflozin had an acceptable safety profile and resulted in less hypoglycemia and more GMIs than glimepiride. CLINICAL TRIAL REGISTRATION Clinicaltrials.gov NCT01999218.

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.

Abstract
INTRODUCTION Ertugliflozin is an oral sodium-glucose cotransporter 2 inhibitor that is being developed to treat type 2 diabetes mellitus (T2DM). This study assessed the efficacy and safety of co-initiation of ertugliflozin and sitagliptin compared with placebo in patients with T2DM inadequately controlled on diet and exercise. METHODS In this phase III, randomized, double-blind, multicenter, placebo-controlled 26-week study (NCT02226003), patients with T2DM and glycated hemoglobin (HbA1c) 8.0-10.5% on diet/exercise were randomized 1:1:1 to ertugliflozin 5 mg once daily (QD) and sitagliptin 100 mg QD (E5/S100), ertugliflozin 15 mg QD and sitagliptin 100 mg QD (E15/S100), or placebo. The primary efficacy endpoint was the change from baseline in HbA1c at week 26. RESULTS The mean baseline HbA1c of the randomized patients (n = 291) was 8.9%. At week 26, both ertugliflozin/sitagliptin treatments provided significant reductions from baseline in HbA1c compared with placebo [least squares mean HbA1c change (95% confidence intervals) from baseline was - 0.4% (- 0.7, - 0.2), - 1.6% (- 1.8, - 1.4), and - 1.7% (- 1.9, - 1.5) for placebo, E5/S100, and E15/S100, respectively]. At week 26, 8.3%, 35.7%, and 31.3% of patients receiving placebo, E5/S100, and E15/S100, respectively, had HbA1c < 7.0%. Significant reductions in fasting plasma glucose, 2-h post-prandial glucose, body weight, and systolic blood pressure were observed with both ertugliflozin/sitagliptin groups compared with placebo. The incidence of adverse events (AEs) was similar across the groups. The incidences of the pre-specified AEs of urinary tract infection, genital mycotic infection, symptomatic hypoglycemia, and hypovolemia were low and not meaningfully different across groups. CONCLUSION Co-initiation of ertugliflozin with sitagliptin in patients with T2DM inadequately controlled on diet and exercise provided a clinically meaningful improvement in glycemic control over 26 weeks.

Abstract
Ertugliflozin is a highly selective and potent inhibitor of the sodium-glucose cotransporter 2 in development for the treatment of type 2 diabetes mellitus. The glycemic efficacy of sodium-glucose cotransporter 2 inhibitors such as ertugliflozin depends on glucose filtration through the kidney. This phase 1, open-label study evaluated the effect of renal impairment on the pharmacokinetics, pharmacodynamics, and tolerability of ertugliflozin (15 mg) in type 2 diabetes mellitus and healthy subjects with normal renal function (estimated glomerular filtration rate not normalized for body surface area ≥90 mL/min) and type 2 diabetes mellitus subjects with mild (60-89 mL/min), moderate (30-59 mL/min), or severe (<30 mL/min) renal impairment (n = 36). Blood and urine samples were collected predose and over 96 hours postdose for pharmacokinetic evaluation and measurement of urinary glucose excretion over 24 hours. Log-linear regression analyses indicated predicted mean area under the concentration-time curve values for mild, moderate, and severe renal function groups that were ≤70% higher relative to subjects with normal renal function. Generally consistent results were obtained with categorical analysis based on analysis of variance. The increase in ertugliflozin exposure in subjects with renal impairment is not expected to be clinically meaningful. Regression analysis of change from baseline in urinary glucose excretion over 24 hours vs estimated glomerular filtration rate showed a decrease in urinary glucose excretion with declining renal function. A single 15-mg dose of ertugliflozin was well tolerated in all groups.

Abstract
AIMS To conduct a phase III study to evaluate the efficacy and safety of ertugliflozin monotherapy in people with type 2 diabetes. MATERIALS AND METHODS This was a 52-week, double-blind, multicentre, randomized, parallel-group study with a 26-week, placebo-controlled treatment period (phase A), followed by a 26-week active-controlled treatment period (phase B) in 461 men and women, aged ≥18 years with inadequate glycaemic control (glycated haemoglobin [HbA1c] concentration 7.0% to 10.5% [53-91 mmol/mol], inclusive) despite diet and exercise. Results from phase A are reported in the present paper. The primary endpoint was the change in HbA1c from baseline to week 26. RESULTS At week 26, the placebo-adjusted least squares mean HbA1c changes from baseline were -0.99% and -1.16% for the ertugliflozin 5 and 15 mg doses, respectively ( P < .001 for both doses). The odds of having HbA1c <7.0% (53 mmol/mol) were significantly greater in the ertugliflozin 5 and 15 mg groups compared with the placebo group. Both doses of ertugliflozin significantly lowered fasting plasma glucose and 2-hour postprandial glucose levels and body weight. The placebo-adjusted differences in changes from baseline in systolic blood pressure were not statistically significant. A higher incidence of genital mycotic infections occurred in men and women treated with ertugliflozin compared with placebo. There was no significant difference between treatments in the proportion of participants with symptomatic hypoglycaemia or adverse events associated with urinary tract infection or hypovolaemia. CONCLUSIONS Ertugliflozin 5 and 15 mg treatment for 26 weeks provides effective glycaemic control, reduces body weight and is generally well tolerated, when used as monotherapy.

Abstract
The propensity for CYP3A4 induction by 2-(6-(5-chloro-2-methoxyphenyl)-4-oxo-2-thioxo-3,4-dihydropyrimidin-1(2H)-yl)acetamide (PF-06282999), an irreversible inactivator of myeloperoxidase, was examined in the present study. Studies using human hepatocytes revealed moderate increases in CYP3A4 mRNA and midazolam-1'-hydroxylase activity in a PF-06282999 dose-dependent fashion. At the highest tested concentration of 300 μM, PF-06282999 caused maximal induction in CYP3A4 mRNA and enzyme activity ranging from 56% to 86% and 47% t0 72%, respectively, of rifampicin response across the three hepatocyte donor pools. In a clinical drug-drug interaction (DDI) study, the mean midazolam Cmax and area under the curve (AUC) values following 14-day treatment with PF-06282999 decreased in a dose-dependent fashion with a maximum decrease in midazolam AUC0-inf and Cmax of ∼57.2% and 41.1% observed at the 500 mg twice daily dose. The moderate impact on midazolam pharmacokinetics at the 500 mg twice daily dose of PF-06282999 was also reflected in statistically significant changes in plasma 4β-hydroxycholesterol/cholesterol and urinary 6β-hydroxycortisol/cortisol ratios. Changes in plasma and urinary CYP3A4 biomarkers did not reach statistical significance at the 125 mg three times daily dose of PF-06282999, despite a modest decrease in midazolam systemic exposure. Predicted DDI magnitude based on the in vitro induction parameters and simulated pharmacokinetics of perpetrator (PF-06282999) and victim (midazolam) using the Simcyp (Simcyp Ltd., Sheffield, United Kingdom) population-based simulator were in reasonable agreement with the observed clinical data. Since the magnitude of the 4β-hydroxycholesterol or 6β-hydroxycortisol ratio change was generally smaller than the magnitude of the midazolam AUC change with PF-06282999, a pharmacokinetic interaction study with midazolam ultimately proved important for assessment of DDI via CYP3A4 induction.

Abstract
AIMS PF-734200 is a potent and selective oral dipeptidyl peptidase-4 (DPP-4) inhibitor. This study assessed the efficacy and safety of PF-734200 at dose rates of 20 and 30 mg/day in subjects with Type 2 diabetes mellitus inadequately controlled on metformin monotherapy. METHODS This was a placebo-controlled, double-blind, randomized, multicentre, 12 week study. Subjects with Type 2 diabetes mellitus were eligible if screening glycosylated haemoglobin (HbA(1c) ) was 7-11% (53.0-96.7 mmol/mol) and they had been receiving metformin monotherapy for ≥2 months. Subjects receiving metformin and an insulin secretagogue or metformin and thiazolidinedione needed to have a screening HbA(1c) of 6.5-9.5% (47.5-80.3 mmol/mol), measured prior to discontinuing the insulin secretagogue or thiazolidinedione. The primary end-point of the study was a change from baseline to week 12 in HbA(1c) levels. RESULTS Baseline characteristics for 289 subjects randomized to PF-734200 or placebo groups were similar (mean age 56.5 years, mean body mass index 32.2 kg/m(2) and mean HbA(1c) 8.2%, 66.1 mmol/mol). In the predefined per protocol data set, least-squares mean HbA(1c) at week 12 was reduced by 0.79 (8.6 mmol/mol 95% confidence interval -1.10 to -0.49, -12.0 to -5.4 mmol/mol) and 0.92% (10.1 mmol/mol; -1.23 to -0.61, -13.4 to -6.7 mmol/mol) in the 20 and 30 mg groups, respectively, compared with placebo. Differences from placebo were statistically significant (P<0.0001), but the differences between the 20 and 30 mg groups were not. The intent-to-treat analysis yielded similar findings. CONCLUSIONS The HbA(1c) was significantly and meaningfully reduced by both doses of PF-734200, but 20 mg appears to be the more appropriate therapeutic dose for Type 2 diabetes mellitus, contingent upon confirmation by long-term controlled studies.

Abstract
AIMS PF-734200 is a potent, selective inhibitor of DPP-IV. This two-part study evaluated the pharmacokinetics (PK) of oral 20mg PF-734200 in subjects with varying degrees of renal insufficiency or with end-stage renal disease (ESRD) requiring chronic haemodialysis (HD). The study also assessed the HD clearance of PF-734200 in ESRD. METHODS Part 1 included subjects with normal renal function or renal insufficiency but not on HD. Subjects received a single dose of 20mg PF-734200 while fasting and serum and urine samples were collected. In part 2, period 1, 1h after HD, a single 20-mg dose was given to subjects with ESRD and serum samples were collected. After a 7-day washout, subjects received another dose followed by collection of serum samples (period 2), during which HD was initiated 4h after dosing. Dialysate samples were collected to quantify amount of drug removed, from which HD clearance was calculated. The fraction of drug dialysed was calculated using an AUC-based method. RESULTS Systemic exposures of PF-734200 increased approximately 1.5-, 2.2-, 2.1- and 2.8-fold in subjects with mild, moderate, or severe renal insufficiency or ESRD, respectively, compared with subjects with normal renal function. The terminal half-life increased from 16.2h in subjects with normal renal function to 36.6h in subjects with ESRD. Approximately, 29% of PF-734200 in the body after a single-dose administration was dialysed by 4h HD. CONCLUSIONS Systemic exposure of PF-734200 increases with decreasing renal function. The effect of HD on drug removal is modest.

Abstract
BACKGROUND Matrix metalloproteinase (MMP)-9, a member of the MMP superfamily is consistently implicated in the pathophysiology of atherosclerosis and plaque rupture, the most common mechanism responsible for acute coronary syndrome (ACS). AIM To summarize the role of MMP-9 in atherosclerosis and its potential implications in assessment and treatment of coronary artery disease (CAD). METHODS We reviewed the PubMed database for relevant data regarding the role of MMP-9 in the pathophysiology of atherosclerosis. In the light of these data, we postulate potential implications of MMP-9 in the management and treatment of CAD. RESULTS AND CONCLUSIONS Existing data strongly support the role of MMP-9 in plaque destabilization and rupture. Based on the current knowledge, MMP-9 can potentially serve as a diagnostic biomarker in ACS and a prognostic biomarker in ACS and chronic CAD patients. MMP-9 is reduced by therapies that are associated with favourable outcome in atherosclerosis and thus may serve as a surrogate biomarker of treatment efficacy. However, large morbidity and mortality trials are still required to confirm that MMP-9 reduction is associated with improved outcome independent of the traditional risk factors (i.e. low-density lipoprotein cholesterol). Given its role in plaque rupture, inhibition of MMP-9 may promote plaque stabilization and consequently reduce cardiovascular events. Yet, the efficacy and safety of MMPs inhibitors should be first studied in preclinical models of atherosclerosis.

Abstract
BACKGROUND Biomarkers of atherosclerosis are emerging as a potential tool for assessment of coronary artery disease (CAD) patients. As acute coronary syndrome (ACS), and stable CAD are distinguished in their pathophysiology it is conceivable that they are also characterized by different biomarkers of atherosclerosis. METHODS We systematically reviewed the literature for clinical studies of several non-traditional biomarkers of atherosclerosis reflecting various pathophysiological processes, namely macrophage-activity, oxidative-stress, tissue remodeling, and thrombosis in ACS and stable CAD to determine whether circulating biomarkers are differently expressed/predict outcome in these two clinical conditions. RESULTS Macrophage-activity (monocyte chemoattractant protein-1, neopterin), tissue-remodeling (matrix metalloproteinase-9) and thrombosis (tissue-factor) related biomarkers were consistently elevated in ACS compared to stable CAD, in accordance with the pathophysiological role of these mediators in plaque rupture, characterizing ACS. Thus, these biomarkers may be applicable for diagnosis of ACS. Additionally, neopterin was consistently shown to predict outcome in both stable and ACS patients and myeloperoxidase was strongly shown to predict outcome in ACS, implying for their potential role in risk stratification of these patients. CONCLUSIONS As ACS and stable CAD are characterized by different pathophysiological processes, it appears that the biomarkers that are associated with them are differently expressed in these two clinical conditions

Abstract
OBJECTIVES The Arg389Gly polymorphism (Arg389Gly) in the beta1-adrenergic receptor gene (ADRB1) has been associated with improvement in left-ventricular remodeling with beta-blocker treatment. One study of risk for heart failure suggested a synergistic effect of ADRB1 Arg389Gly with the insertion/deletion polymorphism in the alpha2C-adrenergic receptor gene (ADRA2C). We tested whether the ADRA2C insertion/deletion polymorphism was associated with beta-blocker response in heart failure, either alone or in combination with the ADRB1Arg389Gly polymorphism. METHODS Fifty-four beta-blocker naive heart failure patients underwent echocardiography before and after 5-6 months of metoprolol CR/XL therapy. Multivariant linear regression modeling was performed to assess the impact of genotypes and other variables on changes in left-ventricular function in response to metoprolol therapy. RESULTS Deletion carriers had a significantly greater negative chronotropic response. Predictors of the end of study ejection fraction were baseline ejection fraction, deletion carrier status and Arg389Arg genotype. Patients with Arg389Arg/Del-carrier status showed the greatest ejection fraction increase with metoprolol CR/XL. Adjusting for baseline ejection fraction, final S-metoprolol plasma concentration and race, final ejection fraction in patients with this genotype combination was significantly higher than all other genotype combination groups. CONCLUSION ADRB1 and ADRA2C polymorphisms synergistically influence the ejection fraction response to beta-blocker therapy of heart failure patients.

Abstract
BACKGROUND The purpose of this study was to compare the effects of immediate-release (IR) metoprolol and extended-release (XL) metoprolol on measures of heart rate variability in chronic systolic heart failure patients. METHODS AND RESULTS Thirteen metoprolol-treated heart failure patients were randomized to a 2-way crossover study of equal daily doses of metoprolol IR and metoprolol XL, each administered for 3 weeks. After each 3-week interval, patients underwent 24-hour Holter and ambulatory blood pressure monitoring. Over the entire 24-hour period, the ratio of high to total variability (normalized measure of parasympathetic activity) was significantly greater (P < .05), the ratio of low to total variability (normalized measure of sympathetic activity) was significantly lower (P < .05), and the ratio of high to low variability (index of parasympathetic to sympathetic balance) was greater (P < .08) for metoprolol XL compared with metoprolol IR. Over the entire 24-hour period, both systolic and diastolic blood pressure were significantly lower for metoprolol XL compared with metoprolol IR (P < .0001, and .0005, respectively). CONCLUSION These data suggest that with twice daily dosing, metoprolol IR is inferior to metoprolol XL in its effects on heart rate variability, autonomic balance, and blood pressure in patients with heart failure.

Abstract
OBJECTIVES The beta-adrenergic receptor (betaAR) genes are candidate genes for obesity because of their roles in energy homeostasis and promotion of lipolysis in human adipose tissue. Objective is to determine the association between obesity and polymorphisms in genes of the beta(1)AR (ADRB1), beta(2)AR (ADRB2), beta(3)AR (ADRB3), Gs protein alpha (GNAS1), to which all three beta-receptors couple and the G protein beta3 subunit (GNB3), to which beta(3)ARs couple. DESIGN A case-control genetic association study. SUBJECTS A total of 643 black or white women enrolled in Women's Ischemia Syndrome Evaluation (WISE) study. MEASUREMENTS Genotypes were determined by PCR with single primer extension. Associations between genotype and body mass index (BMI), waist-to-hip ratio (WHR), waist circumference, and obesity were made. RESULTS Polymorphisms in the three betaAR genes, GNAS1, and GNB3 were not associated with BMI, WHR, waist circumference, or obesity. Linear and logistic regression analyses found no contribution of either genotype or haplotype with anthropometric measurements or obesity. CONCLUSIONS Our study suggests that among American women with suspected coronary heart disease, polymorphisms in the betaARs and their G-protein-coupled receptors do not contribute to increased BMI, WHR, waist circumference, or obesity. Given that 50% of all women die from coronary heart disease, and a higher percentage have heart disease during their lifetime, our results are likely generalizable to many American women.

Abstract
OBJECTIVE Large variability exists in the improvement in left ventricular (LV) function from beta-blocker treatment. We hypothesized that polymorphisms at codon 389 (Arg389Gly) and 49 (Ser49Gly) in the beta1-adrenergic receptor (AR) gene were associated with LV reverse remodeling changes in response to beta-blocker therapy among heart failure patients. METHODS We prospectively enrolled 61 beta-blocker naive patients with systolic heart failure. Patients underwent baseline echocardiography followed by metoprolol CR/XL. The dose was doubled on a biweekly basis up to 200 mg/day or attainment of maximum tolerated dose. Echocardiography was repeated after the patient received the target or highest tolerated dose for 3 months. RESULTS Among patients with the Arg389Arg genotype, ejection fraction (EF) increased from 23+/-5 to 29+/-10 (P=0.008). Gly389 carriers did not demonstrate any significant change in EF (22+/-9 to 23+/-11; P=0.45). There was a significant between-group difference in EF by genotype (P=0.04). The Arg389Arg genotype was also associated with significantly greater reductions in LV end-diastolic and end-systolic diameters compared to Gly389 carriers. Patients with the Gly49 variant also had a significantly greater reduction in LV end-diastolic diameter compared to Ser49 homozygotes. Multiple regression analysis modeling revealed that the codon 389 polymorphism was a significant predictor of an improvement in EF and both codon 49 and 389 polymorphisms were significant predictors of final LV end-diastolic diameter. CONCLUSIONS Heart failure patients with the Arg389Arg genotype and Gly49 carriers had greater improvements in LV remodeling from beta-blocker treatment.
