Efficacy and safety of ertugliflozin in patients with type 2 diabetes mellitus and established cardiovascular disease using insulin: A VERTIS CV substudy.

AimTo assess the efficacy and safety of ertugliflozin in patients with type 2 diabetes mellitus (T2DM) and established atherosclerotic cardiovascular disease (ASCVD) inadequately controlled by insulin.Materials and methodsVERTIS CV was the cardiovascular outcome study for ertugliflozin. Patients were randomly assigned to placebo, or ertugliflozin 5 mg or 15 mg once daily. We report the results of a substudy in patients on a stable dose of insulin ≥20 units/d. The primary endpoint was glycated haemoglobin (HbA1c) change from baseline to 18 weeks. Secondary endpoints were changes in fasting plasma glucose (FPG), body weight (BW), the proportion of patients with HbA1c <53 mmol/mol (<7%), systolic blood pressure (SBP), diastolic blood pressure and insulin dose.ResultsOf 8246 patients randomized in VERTIS CV, 1065 were included in the substudy (68.2% men, mean [SD] age 64.8 [7.8] years, T2DM duration 16.7 [9.0] years, HbA1c 8.4 [1.0]%). At week 18, the least squares (LS) mean change from baseline in HbA1c was significantly greater with ertugliflozin 5 mg and 15 mg versus placebo (placebo‐adjusted LS mean change −0.58%, 95% confidence interval [CI] −0.71, −0.44 and −0.65%, 95% CI −0.78, −0.51, respectively; P < 0.001 for both). Ertugliflozin significantly reduced FPG, BW and SBP. In women, the incidence of genital mycotic infections was higher with ertugliflozin (3.5%) versus placebo (0.0%). The incidence of symptomatic hypoglycaemia was similar across treatment groups.ConclusionsErtugliflozin added to insulin improved glycaemic control, BW and SBP versus placebo at 18 weeks in patients with T2DM and ASCVD.

A randomized, placebo-controlled study to evaluate the efficacy and safety of adding omarigliptin to insulin therapy in Japanese patients with type 2 diabetes and inadequate glycaemic control.

AimTo evaluate the efficacy and safety of adding the once‐weekly oral dipeptidyl peptidase‐4 inhibitor omarigliptin to treatment of Japanese patients with type 2 diabetes and inadequate glycaemic control on insulin monotherapy.Materials and MethodsIn a 52‐week clinical trial, Japanese patients on insulin monotherapy were randomized to once‐weekly omarigliptin 25 mg (N = 123) or placebo (N = 61) for a 16‐week, double‐blind, placebo‐controlled period. After Week 16, patients continued or switched to omarigliptin for a 36‐week open‐label period.ResultsFrom a mean baseline of approximately 8.8%, the Week 16 least squares mean changes in HbA1c were −0.61% (omarigliptin) and 0.29% (placebo); the between‐group difference was −0.90% (p < .001). At Week 52, the mean change from baseline in HbA1c was −0.57% in both the group on omarigliptin for 52 weeks and the group on omarigliptin for 36 weeks (switched from placebo at Week 16). During the first 16 weeks of treatment, the incidences of adverse events (AEs), serious AEs, drug‐related AEs and discontinuation from trial medication because of an AE were similar in both groups. A slight increase in incidence of symptomatic hypoglycaemia was observed in the omarigliptin group (n = 13 [10.6%]) compared with placebo (n = 4 [6.6%]). No severe hypoglycaemia was reported during the study. No new safety signals emerged with treatment beyond Week 16 through Week 52.ConclusionThe addition of once‐weekly omarigliptin to insulin therapy for up to 52 weeks was generally well tolerated and provided clinically meaningful improvement in glycaemic control throughout the trial period.

Clinical Characteristics and Glycemic Outcomes of Patients with Type 2 Diabetes Requiring Maximum Dose Insulin Glargine/Lixisenatide Fixed-Ratio Combination or Insulin Glargine in the LixiLan-L Trial.

IntroductioniGlarLixi is a titratable, fixed-ratio combination of insulin glargine (iGlar, 100 units/ml) and the glucagon-like peptide-1 receptor agonist lixisenatide for the treatment of patients with type 2 diabetes. This post hoc analysis of the phase 3 LixiLan-L trial (NCT02058160) investigated baseline characteristics, glycemic control, and safety outcomes in participants who received the study-specified maximum dose (60 units/day) of iGlarLixi or iGlar vs. those who received < 60 units/day.MethodsOutcomes were compared for participants receiving 60 or < 60 units/day at week 30. Endpoints analyzed included change in A1C, fasting plasma glucose (FPG), 2-h postprandial glucose (2-h PPG), body weight, proportion of participants achieving A1C < 7.0%, proportion of participants receiving rescue therapy, documented symptomatic hypoglycemia, and gastrointestinal adverse event (GI AE) incidence.ResultsBy week 30, 27% (iGlarLixi) and 31% (iGlar) of participants received the maximum dose. Participants on 60 vs. < 60 units/day were younger and had higher body weight, body mass index (BMI), FPG, and baseline insulin dose. In both dose groups, A1C change from baseline was significantly greater with iGlarLixi vs. iGlar, and more participants treated with iGlarLixi vs. iGlar achieved A1C < 7.0%. No significant differences were observed in change from baseline for A1C, FPG, 2-h PPG, or GI AE incidence between insulin dose groups, regardless of treatment. In both treatment arms, incidence of symptomatic hypoglycemia was lower in participants receiving 60 units/day vs. those receiving < 60 units/day. Participants treated with iGlarLixi (< 60 or 60 units/day) had modest weight loss over 30 weeks vs. an increase in weight compared with iGlar.ConclusionsMaximum doses of iGlarLixi were required in participants with a more insulin-resistant clinical phenotype (younger, higher BMI, FPG, and insulin doses). Benefits were observed with iGlarLixi vs. iGlar, even at 60 units/day, with more participants achieving glycemic goals, no increase in symptomatic hypoglycemia, and a modest reduction in body weight.FundingSanofi US, Inc.Electronic Supplementary MaterialThe online version of this article (10.1007/s12325-019-01033-1) contains supplementary material, which is available to authorized users.

Safety and efficacy of ertugliflozin in Asian patients with type 2 diabetes mellitus inadequately controlled with metformin monotherapy: VERTIS Asia.

AimPhase 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 methodsA 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.ResultsAt 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.ConclusionsErtugliflozin 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.

Results of VERTIS SU extension study: safety and efficacy of ertugliflozin treatment over 104 weeks compared to glimepiride in patients with type 2 diabetes mellitus inadequately controlled on metformin

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.Trial registration: ClinicalTrials.gov identifier: NCT01999218.

Incidence and risk factors associated with hypoglycemia in the first 48 hours of life in Small for Gestational Age Neonates

Background: Hypoglycemia is one of the important problems encountered in small for gestational age (SGA) neonates. The incidence and risk factors associated with hypoglycemia in the first 48 hours of life in Small for Gestational Age (SGA) Neonates was investigated in this study.Methods: Capillary Blood Glucose was screened by glucostix at 1, 2, 6, 12, 24, and 48 hours of age in 100 SGA neonates fulfilling the inclusion and exclusion criteria.Results: The overall incidence of hypoglycemia in SGA neonates in the study was 24%. The incidence of hypoglycemia was significantly higher in preterm SGA neonates (37.50%) when compared to term SGA neonates (17.65%). The incidence of symptomatic hypoglycemia was 9%. Maximum incidence of hypoglycemia was noted at 2 hours of life. Of the 24 SGA neonates with hypoglycemia, 33.33% had one episode of hypoglycemia, 45.83% had two episodes of hypoglycemia, 12.50% had three episodes of hypoglycemia, 8.33% had four episodes of hypoglycemia. None of the SGA neonate had more than four episodes of hypoglycemia. Early initiation of enteral feeding was significantly associated with decreased incidence of hypoglycemia in SGA neonates. There was no significant correlation between incidence of hypoglycemia in SGA neonates and gender of the baby, parity of mother, mode of delivery and type of IUGR.Conclusions: It is recommended to monitor all SGA neonates especially preterm SGA for hypoglycemia and ensure early initiation of enteral feeding in all SGA neonates.

Efficacy and safety of sitagliptin added to treatment of patients with type 2 diabetes inadequately controlled with premixed insulin.

To improve understanding of the safety and efficacy of adding sitagliptin to treatment of patients with type 2 diabetes taking premixed insulin, data from patients using premixed insulin ± metformin (screening HbA1c ≥7.5% and ≤11%) in either of two clinical trials in which sitagliptin 100 mg once-daily or placebo was added to various formulations of insulin treatment, were analysed. In both trials, insulin doses were to remain stable throughout the 24-week trial period. At week 24, the between-group difference (sitagliptin - placebo) in the least squares mean (95% confidence intervals) change from baseline in HbA1c in patients using premixed insulin was -0.43% (-0.58, -0.28), P <0.001. Adverse events were generally similar between the treatment groups. The incidence of symptomatic hypoglycaemia was slightly higher with sitagliptin, and the incidence of hypoglycaemia requiring medical attention was slightly higher with placebo; in both cases the difference was not statistically significant. The data from this pooled analysis confirm the utility of sitagliptin used in combination with premixed insulin in patients with type 2 diabetes.

The current status of treatment-related severe hypoglycemia in Japanese patients with diabetes mellitus: A report from the committee on a survey of severe hypoglycemia in the Japan Diabetes Society.

Despite great strides in pharmacotherapy for diabetes, there is increasing concern over the risk of hypoglycemia in patients with diabetes receiving pharmacotherapy as they become increasingly older. This has prompted the Japan Diabetes Society (JDS) to initiate a survey on the current status of severe hypoglycemia in clinical settings. In July 2015, following approval from the JDS Scientific Survey/Research Ethics Committee, the JDS extended an invitation to executive educators, who represented a total of 631 healthcare facilities accredited by the JDS for diabetes education, to participate in the proposed survey. Of these, those who expressed their willingness to participate in the survey were sent an application form required for obtaining ethical approval at these healthcare facilities and were then asked, following approval, to enter relevant clinical data on an unlinked, anonymous basis in a web‐based registry. The current survey was fully funded by the JDS Scientific Survey/Research Committee. A case registry (clinical case database) was launched after facility‐specific information (healthcare facility database) was collected from all participating facilities and after informed consent was obtained from all participating patients. With severe hypoglycemia defined as the “presence of hypoglycemic symptoms requiring assistance from another person to treat and preferably venous plasma glucose levels at onset/diagnosis of disease or at presentation clearly less than 60 mg/dL (capillary whole blood glucose, less than 50 mg/dL)”, the current survey was conducted between April 1, 2014 and March 31, 2015, during which facility‐specific information was collected from a total of 193 facilities with a total of 798 case reports collected from 113 facilities. Of the 193 respondent facilities, 149 reported having an emergency department as well, with the median number of patients who required emergency transportation services to reach these facilities totaling 4,962 annually, of which those with severe hypoglycemia accounted for 0.34% (17). The respondent facilities accommodated a total of 2,237 patients with severe hypoglycemia annually, with the number of patients thus accommodated being 6.5 patients per site. A total of 1,171 patients were admitted for severe hypoglycemia, with the number of patients thus admitted being 4.0 per site, who accounted for 52.3% of all patients visiting annually for severe hypoglycemia. A review of the 798 case reports collected during the survey revealed that 240, 480 and 78 patients had type 1 diabetes, type 2 diabetes, and other types of diabetes, respectively; those with type 2 diabetes were shown to be significantly older (median [interquartile range], 77.0 [68.0–83.0]) than those with type 1 diabetes (54.0 [41.0–67.0]) (P < 0.001); and the BMI was shown to be significantly higher for those with type 2 diabetes (22.0 [19.5–24.8] kg/m2) than for those with type 1 diabetes (21.3 [18.9–24.0] kg/m2) (P = 0.003). It was also found that the median estimated glomerular filtration rate (eGFR) was significantly lower among those with type 2 diabetes (50.6 mL [31.8–71.1]/min/1.73 m2) than among those with type 1 diabetes (73.3 [53.5–91.1] mL/min/1.73 m2) (P < 0.001). Again, the median HbA1c value at onset of severe hypoglycemia was shown to be 7.0 (6.3–8.1)% among all patients examined, 7.5 (6.9–8.6)% among those with type 1 diabetes, and 6.8 (6.1–7.6)% among those with type 2 diabetes, with the HbA1c value at onset of hypoglycemia being significantly lower among those with type 2 diabetes (P < 0.001). Antecedent symptoms of severe hypoglycemia were shown to be present, absent and unknown in 35.5, 35.6, and 28.9% of all patients, respectively, with the incidence of symptomatic hypoglycemia being significantly lower among those with type 1 diabetes (41.0%) than among those with type 2 diabetes (56.9%). The antidiabetic agents used in those with type 2 diabetes were insulin preparations (292 patients including 29 receiving concomitant sulfonylureas [SUs]) (60.8%), SUs (159 insulin‐naïve patients) (33.1%), and no insulin preparations or SUs (29 patients) (6.0%). Of the 798 patients surveyed, 296 patients (37.2%) were shown to have required emergency transportation services for severe hypoglycemia before. Thus, the survey revealed, for the first time, the current status of treatment‐related severe hypoglycemia in Japan and clearly highlights the acute need for implementing preventive measures against hypoglycemia not only through education on hypoglycemia but through optimization of antidiabetic therapy for those at high risk of severe hypoglycemia or those with a history of severe hypoglycemia.

Clinical Benefit of Basal Insulin Analogue Treatment in Persons with Type 2 Diabetes Inadequately Controlled on Prior Insulin Therapy: A Prospective, Noninterventional, Multicenter Study.

IntroductionBasal insulin analogues offer persons with type 2 diabetes mellitus (T2DM) adequate glycemic control combined with a favorable safety profile. BASAL-BALI—a prospective, noninterventional, multicenter disease registry—assessed the effectiveness and safety of basal insulin analogues in adult Serbians with T2DM previously inadequately controlled on other insulin types.MethodsThe primary objective was to assess the reduction in glycated hemoglobin (HbA1c) from basal insulin analogue initiation to the end of a 6-month observation period. Data collection was performed at three study visits: baseline, 3 months, and 6 months. All treatments and procedures were performed at the physicians’ discretion.ResultsIn total, 460 subjects were included. Mean diabetes duration was 11.6 ± 6.6 years. Late complications of diabetes were present in 67% of subjects and comorbidities in 85%. After 6 months, the mean reduction in HbA1c was 1.8% (p < 0.01 vs. baseline); body weight (mean reduction of 0.9 kg, p < 0.01), waist circumference (1.5 cm, p < 0.01), and BMI (0.2 kg/m2, p < 0.01) were also reduced. A total of 49.1% of subjects reached their individualized HbA1c treatment target, and 42.0% met the composite HbA1c and fasting plasma glucose (FPG) target. The incidence of symptomatic hypoglycemia was reduced from 96.3% in the 6 months prior to initiating basal insulin analogues to 15.4% over the 6-month treatment period.ConclusionIntroducing basal insulin analogues in persons with T2DM previously inadequately controlled on other insulin types can significantly improve glycemic control and reduce the risk of hypoglycemia, without adversely affecting body weight.FundingSanofi, Serbia.Electronic supplementary materialThe online version of this article (10.1007/s13300-018-0378-4) contains supplementary material, which is available to authorized users.

Ertugliflozin Compared with Glimepiride in Patients with Type 2 Diabetes Mellitus Inadequately Controlled on Metformin: The VERTIS SU Randomized Study.

IntroductionThis 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.MethodsThis 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%).ResultsMean 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.ConclusionsErtugliflozin 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 RegistrationClinicaltrials.gov NCT01999218.Electronic supplementary materialThe online version of this article (10.1007/s13300-017-0354-4) contains supplementary material, which is available to authorized users.

A randomized, placebo-controlled clinical trial evaluating the safety and efficacy of the once-weekly DPP-4 inhibitor omarigliptin in patients with type 2 diabetes mellitus inadequately controlled by glimepiride and metformin

BackgroundType 2 diabetes (T2D) is a progressive disease that often requires a patient to use multiple antihyperglycemic agents to achieve glycemic control with disease progression. Omarigliptin is a once-weekly dipeptidyl peptidase-4 inhibitor. The purpose of this trial was to assess the efficacy and safety of adding omarigliptin to the treatment regimen of patients with T2D inadequately controlled by dual therapy with metformin and glimepiride.MethodsPatients with T2D and HbA1c ≥7.5% and ≤10.5% while on metformin (≥1500 mg/day) and glimepiride (≥4 mg/day) were randomized to omarigliptin 25 mg once-weekly (N = 154) or placebo (N = 153) for 24 weeks. The primary objective was to assess whether omarigliptin was superior to placebo in reducing HbA1c at Week 24. Secondary objectives were to assess the effects of omarigliptin vs. placebo on FPG and the proportion of subjects attaining HbA1c goals of <7% and <6.5%.ResultsFrom a mean baseline HbA1c of 8.5% (omarigliptin) and 8.6% (placebo), the least squares (LS) mean change from baseline in HbA1c at Week 24 was −0.67% in the omarigliptin group and −0.06% in the placebo group, with a between-group difference (95% CI) of −0.61% (−0.85, −0.38). Treatment with omarigliptin resulted in a significantly greater reduction in FPG relative to placebo (LS mean difference [95% CI] -0.9 mmol/L [−1.4, −0.4]; p < 0.001). The proportion of patients achieving glycemic goals of <7.0% and <6.5% was higher in the omarigliptin group relative to the placebo group. The overall incidences of adverse events (AEs), serious AEs, drug-related AEs and discontinuations were generally similar between treatment groups. The incidence of symptomatic hypoglycemia was 10.5% in the omarigliptin group and 8.5% in the placebo group. Relative to baseline, omarigliptin and placebo treatments were associated with LS mean changes in body weight of −0.1 kg and −0.9 kg, respectively.ConclusionIn patients with T2D and inadequate glycemic control on dual therapy with metformin and glimepiride, compared with placebo, once-weekly omarigliptin provided greater improvement in glycemic control and was generally well tolerated.Trial registrationClinicalTrials.gov: NCT01704261, EudraCT Number: 2012-002612-10.

A randomized, double-blind, non-inferiority trial evaluating the efficacy and safety of omarigliptin, a once-weekly DPP-4 inhibitor, or glimepiride in patients with type 2 diabetes inadequately controlled on metformin monotherapy

Objective: To evaluate the efficacy and safety of adding the once-weekly DPP-4 inhibitor omarigliptin or the sulfonylurea glimepiride to the treatment regimen of patients with type 2 diabetes (T2DM) and inadequate glycemic control on metformin monotherapy.Methods: Patients with T2DM and HbA1c ≥6.5% to ≤9.0% while on a stable dose of metformin (≥1500 mg/day) were randomized to omarigliptin 25 mg once-weekly (n = 376) or glimepiride up to 6 mg once daily (n = 375) for 54 weeks. The primary hypothesis was that omarigliptin is non-inferior to glimepiride in reducing HbA1c at week 54.Results: The mean baseline HbA1c was 7.5% in the omarigliptin group and 7.4% in the glimepiride group. After 54 weeks, the least squares (LS) mean change from baseline in HbA1c was –0.30% in the omarigliptin group and –0.48% in the glimepiride group, with a between-group difference (95% CI) of 0.18% (0.06, 0.30), which met the pre-specified criterion for declaring non-inferiority. The incidence of symptomatic hypoglycemia was 5.3% in the omarigliptin group and 26.7% in the glimepiride group. With the exception of hypoglycemia, the incidences of adverse events and discontinuations were similar between treatment groups. Relative to baseline, omarigliptin was associated with a mean weight loss (−0.4 kg) and glimepiride a mean weight gain (+1.5 kg).Conclusions: After 54 weeks, as add-on therapy to metformin, once-weekly omarigliptin was generally well tolerated and non-inferior to glimepiride in improving glycemic control, with a lower incidence of hypoglycemia and with weight loss vs weight gain.

Efficacy and safety of coadministration of sitagliptin with insulin glargine in type 2 diabetes.

The aim of the randomized present study was to compare the therapeutic efficacy and safety of a combination of sitagliptin, a dipeptidyl peptidase (DPP)-4 inhibitor, plus insulin glargine (GL + sita) with that of premixed insulin aspart 30 (NOV) for type 2 diabetes (T2D) patients controlled with oral hypoglycemic drugs (HbA1c 7%-9%). Sixty-five patients were randomized (1: 1) to the GL + sita (n = 33) and NOV (n = 32) groups and were treated with the combination regimen or premixed insulin twice a day for 16 weeks. The primary endpoint was mean change in HbA1c. Secondary endpoints included fasting blood glucose, blood glucose profiles (seven time points), rate of achieving target HbA1c (<7% or ≤6.5%), insulin dose, incidence of hypoglycemia, and body weight. After 16 weeks, there was no significant difference in HbA1c between the two groups, although more patients achieved HbA1c <7.0% in the GL + sita group. There was a significant difference in body weight changes between the GL + sita and NOV groups (-0.45 vs 1.52 kg, respectively; P <0.001). Mean plasma glucose and the mean amplitude of glycemic excursion were significantly lower in the GL + sita than NOV group (P <0.005), as was the incidence of symptomatic hypoglycemia (2.85% vs. 13.3%, respectively; P <0.001). The combination of GL + sita greatly improved HbA1c in T2D patients (HbA1c 7%-9%) with an efficacy that was equal to that of premixed insulin. Thus, GL + sita treatment is a viable option for patients who fail to achieve glycemic control using oral hypoglycemic drugs.

Randomized clinical trial of the safety and efficacy of sitagliptin and metformin co-administered to Chinese patients with type 2 diabetes mellitus.

IntroductionThe results of a clinical trial to evaluate the efficacy and safety of initial combination therapy with sitagliptin and metformin in Chinese patients with type 2 diabetes and inadequate glycemic control are reported here.Materials and MethodsThis was a multicenter, randomized, double‐blind, placebo‐controlled, parallel group, 24‐week clinical trial carried out in China. Patients (n = 744) with type 2 diabetes and inadequate glycemic control (glycated hemoglobin ≥7.5 and ≤11.0%) who were either drug‐naïve or washed out of previous therapy were randomized in equal ratios to sitagliptin 100 mg once daily (q.d.; S100), metformin 500 mg twice daily (b.i.d.; M1000), metformin 850 mg b.i.d. (M1700), sitagliptin 50 mg b.i.d. plus metformin 500 mg b.i.d. (S100/M1000), sitagliptin 50 mg b.i.d. plus metformin 850 mg b.i.d. (S100/M1700), or placebo.ResultsThe mean baseline glycated hemoglobin in randomized patients was 8.7%. Least squares mean changes from baseline in glycated hemoglobin were −0.59% (placebo), −0.99% (S100), −1.29% (M1000), −1.56% (M1700), −1.67% (S100/M1000) and −1.83% (S100/M1700) (P < 0.05 for each active group vs placebo, for S100/M1700 and S100/M1000 vs S100, and for S100/M1000 vs M1000). All treatments were generally well‐tolerated. The overall incidence of hypoglycemia (symptomatic or asymptomatic) was higher in the two co‐administration groups (S100/M1700 and S100/M1000) compared with the placebo. The incidence of symptomatic hypoglycemia was low, and similar, across all treatment groups. The incidences of gastrointestinal adverse events were generally higher in high‐dose metformin groups than in the placebo group.ConclusionsIn Chinese patients with type 2 diabetes, initial combination therapy with sitagliptin and metformin was generally well‐tolerated, and provided improvement in glycemic control.

Efficacy and Safety of Lixisenatide in Japanese Patients with Type 2 Diabetes Insufficiently Controlled with Basal Insulin±Sulfonylurea: A Subanalysis of the GetGoal-L-Asia Study.

The aim of the study was to evaluate the efficacy and safety of once-daily lixisenatide 20 μg as add-on to basal insulin with or without sulfonylurea in Asian patients with type 2 diabetes mellitus. The study as a subanalysis of the 159 Japanese patients from the 24-week double-blind GetGoal-L-Asia study (NCT00866658) who received once-daily lixisenatide or placebo. The primary endpoint was change from baseline in HbA1c evaluated using analysis of covariance. Once-daily lixisenatide significantly reduced mean HbA1c [least squares mean difference vs. placebo - 1.1% (- 12 mmol/mol); p<0.0001]. Significantly more patients in the lixisenatide group reached HbA1c targets of < 7% (53 mmol/mol; 31.4 vs. 2.3% for placebo; p<0.0001) and ≤ 6.5% (48 mmol/mol; 12.9 vs. 1.2% for placebo; p=0.0028). Lixisenatide significantly reduced 2-h postprandial plasma glucose (least squares mean difference vs. placebo-8.64 mmol/l; p<0.0001), glucose excursion (least squares mean difference vs. placebo - 7.80 mmol/l; p<0.0001) and fasting plasma glucose (least squares mean difference vs. placebo - 0.96 mmol/l; p=0.0126). Body weight was reduced with lixisenatide but with no significant difference vs. placebo. Gastrointestinal adverse events were more frequent with lixisenatide (61.1 vs. 11.5% for placebo) but were generally transient and mild-to-moderate in intensity. The incidence of symptomatic hypoglycemia was 39.0 vs. 13.5% in patients receiving sulfonylureas and 32.3 vs. 22.9% in those not receiving sulfonylureas, for lixisenatide and placebo, respectively. In Japanese patients with type 2 diabetes mellitus, once-daily lixisenatide was well tolerated and led to significant and clinically relevant improvement in glycemic control, with a pronounced effect on postprandial plasma glucose.

Efficacy and Tolerability of Sitagliptin Compared with Glimepiride in Elderly Patients with Type 2 Diabetes Mellitus and Inadequate Glycemic Control: A Randomized, Double-Blind, Non-Inferiority Trial.

The aim of this study was to evaluate the efficacy and tolerability of sitagliptin compared with glimepiride in elderly patients with type 2 diabetes mellitus (T2DM) and inadequate glycemic control with diet and exercise alone. This was a randomized, parallel-group, multinational, non-inferiority clinical trial with an active-controlled, double-blind treatment period in which patients ≥ 65 and ≤ 85 years of age with T2DM were screened at 85 sites. Patients were randomized to once-daily sitagliptin (100 or 50 mg, depending on renal function) or glimepiride (in titrated doses) for 30 weeks. The main outcome measures were change from baseline in glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), and body weight; and the incidence of symptomatic hypoglycemia. The mean baseline HbA1c was 7.8% in both the sitagliptin group (n = 197) and the glimepiride group (n = 191). After 30 weeks, the least squares (LS) mean change in HbA1c baseline was -0.32% with sitagliptin and -0.51 % with glimepiride, for a between-group difference (95% CI) of 0.19% (0.03-0.34). This result met the pre-specified criterion for declaring non-inferiority, which required that the upper 95% confidence limit lie below 0.4%. The LS mean change in FPG from baseline was -14.5 mg/dL with sitagliptin and -21.2 mg/dL with glimepiride, for a between-group difference (95% CI) of 6.7 mg/dL (0.7-12.7). The percentages of patients with adverse events of symptomatic hypoglycemia were 0.8% in the sitagliptin group and 4.7% in the glimepiride group (between-treatment difference = -3.9%, p = 0.009). The LS mean change in body weight from baseline was 0.4 kg with sitagliptin and 1.1 kg with glimepiride, for a between-group difference of -0.7 kg (p = 0.011). In elderly patients with T2DM and inadequate glycemic control with diet and exercise alone, sitagliptin provided non-inferior glycemic control after 30 weeks of treatment compared with glimepiride. Compared with glimepiride, sitagliptin had a lower risk of hypoglycemia. Sitagliptin was weight-neutral; while the between-group difference in change from baseline in body weight was statistically significant, the modest difference may not be clinically meaningful.

Comparison of treatment with sitagliptin or sulfonylurea in patients with type 2 diabetes mellitus and mild renal impairment: a post hoc analysis of clinical trials.

IntroductionImpaired renal function is a major complication of type 2 diabetes mellitus (T2DM). Mild renal impairment is present in 38% of patients with T2DM and may impact choice of antihyperglycemic agent. Sulfonylureas and dipeptidyl peptidase-4 (DPP-4) inhibitors are commonly used to treat hyperglycemia in patients with T2DM and renal impairment. Although in general sulfonylurea use is associated with an increased risk of hypoglycemia and weight gain, while DPP-4 inhibitor use is associated with a low risk of hypoglycemia, and is weight neutral, the relative efficacy and tolerability of these agents in patients with mild renal impairment has not been evaluated.MethodsIn a post hoc analysis, data from 1,211 subjects with T2DM and mild renal impairment (estimated glomerular filtration rates of 60 to <90 mL/min/1.73 m2), who completed 25 or 30 weeks of one of three double-blind clinical trials comparing the DPP-4 inhibitor sitagliptin 100 mg/day with sulfonylureas in titrated doses, were pooled. The analysis compared change from baseline in glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), body weight, incidence of symptomatic hypoglycemia and the percentages of subjects meeting a composite endpoint of HbA1c decrease >0.5% without symptomatic hypoglycemia or body weight gain between sitagliptin and sulfonylurea treatment groups.ResultsHbA1c and FPG decreased similarly with sitagliptin or sulfonylurea. A lower incidence of hypoglycemia was observed with sitagliptin. Body weight decreased with sitagliptin but increased with sulfonylurea. A greater percentage of subjects treated with sitagliptin (41.1%) than treated with sulfonylurea (16.9%) achieved the composite endpoint of >0.5% HbA1c reduction with no symptomatic hypoglycemia or body weight gain.ConclusionIn this analysis of subjects with T2DM and mild renal impairment, treatment with sitagliptin provided glycemic efficacy similar to sulfonylurea, with less hypoglycemia and with body weight loss compared to body weight gain seen with sulfonylurea.

Lixisenatide treatment improves glycaemic control in Asian patients with type 2 diabetes mellitus inadequately controlled on metformin with or without sulfonylurea: a randomized, double‐blind, placebo‐controlled, 24‐week trial (GetGoal‐M‐Asia)

This study assessed the efficacy and safety of the once-daily glucagon-like peptide-1 receptor agonist, lixisenatide, in Asian patients with type 2 diabetes mellitus inadequately controlled on metformin ± sulfonylurea. In this 24-week, double-blind, placebo-controlled, multinational study, patients were randomized to lixisenatide 20 µg once daily or placebo. The primary endpoint was absolute change in glycated haemoglobin (HbA1c ) from baseline to week 24. A total of 391 patients were randomized. Lixisenatide significantly reduced HbA1c levels compared with placebo (LS mean difference: -0.36%, p = 0.0004). A significantly higher proportion of lixisenatide-treated patients achieved HbA1c targets of <7% (p = 0.003) and ≤6.5% (p = 0.001) versus placebo. Lixisenatide was associated with a statistically significant reduction in 2-h postprandial plasma glucose after a standardized breakfast versus placebo (LS mean difference: -4.28 mmol/L, p < 0.0001) and a significant reduction in fasting plasma glucose (p = 0.0109). There was no difference in weight loss versus placebo, with a modest reduction in body weight reported for both groups (lixisenatide: -1.50 kg, placebo: -1.24 kg; p = 0.296). The incidence of treatment-emergent adverse events (TEAEs) was 64.3% with lixisenatide versus 47.4% with placebo, with serious TEAEs reported in 1.5% versus 2.1% of patients, respectively. The most common TEAE in the lixisenatide group was nausea (16.3% vs 2.6% with placebo). The incidence of symptomatic hypoglycaemia was 5.6% with lixisenatide treatment and 2.6% with placebo (p = 0.1321), with no severe symptomatic hypoglycaemia events reported. In Asian patients with type 2 diabetes mellitus insufficiently controlled on metformin ± sulfonylurea, lixisenatide significantly improved glycaemic control and was well tolerated during the 24-week study.

Efficacy and safety of lixisenatide in Japanese patients with type2 diabetes mellitus inadequately controlled by sulfonylurea with or without metformin: Subanalysis of GetGoal-S.

Aims/IntroductionThis was a subanalysis of Japanese patients included in the glucagon-like peptide-1 receptor agonist AVE0010 in patients with type 2 diabetes mellitus for glycemic control and safety evaluation (GetGoal-S) study – a 24-week, randomized, placebo-controlled study of lixisenatide in patients with type 2 diabetes mellitus inadequately controlled by sulfonylurea with or without metformin.Materials and MethodsIn GetGoal-S, 127 Japanese patients received the once-daily prandial glucagon-like peptide-1 receptor agonist lixisenatide 20 μg/day or a matching placebo. The primary outcome was change in glycated hemoglobin.ResultsAt week 24, lixisenatide significantly reduced mean glycated hemoglobin (least squares mean difference vs the placebo −1.1% [12 mmol/mol, P < 0.0001]), and significantly more lixisenatide patients reached glycated hemoglobin targets of <7% (53 mmol/mol) and ≤6.5% (48 mmol/mol) vs the placebo. Lixisenatide produced statistically significant reductions in 2-h postprandial plasma glucose (least squares mean difference vs the placebo −8.51 mmol/L, P < 0.0001) and glucose excursion vs the placebo, and significantly reduced fasting plasma glucose (least squares mean difference vs the placebo −0.65 mmol/L, P = 0.0454). Bodyweight decreased with both lixisenatide and the placebo (least squares mean change −1.12 kg for lixisenatide, −1.02 kg for placebo). The overall incidence of adverse events was similar for lixisenatide and the placebo (84.2 and 82.4%, respectively), the most frequent being gastrointestinal disorders (52.6% for lixisenatide vs 29.4% for placebo). The incidence of symptomatic hypoglycemia was higher with lixisenatide vs the placebo (17.1 and 9.8%, respectively), with no cases of severe symptomatic hypoglycemia in either group.ConclusionsIn the Japanese subpopulation of the GetGoal-S study, lixisenatide produced a significant and clinically relevant improvement in glycated hemoglobin, with a pronounced improvement in postprandial plasma glucose, and a good safety and tolerability profile.

Efficacy and safety of lixisenatide in elderly (≥65 years old) and very elderly (≥75 years old) patients with type 2 diabetes: an analysis from the GetGoal phase III programme.

The objective of this article is to evaluate the pharmacokinetics, efficacy and safety of lixisenatide (subcutaneous injection) in elderly (≥65 years old) and very elderly (≥75 years old) patients with type 2 diabetes mellitus. We conducted a phase I, single-centre, open-label study to evaluate the safety and pharmacokinetics of a single lixisenatide 20 µg dose and a pooled analysis of six randomized, placebo-controlled, phase III studies (12-month or 24-month duration) that evaluated glycaemic parameters and safety in patients receiving lixisenatide 20 µg once daily or placebo. The pharmacokinetics study included 36 healthy subjects, including 18 elderly healthy subjects (≥65 years old) and 18 matched young healthy subjects (18-45 years old). The pooled analysis included 3188 patients, including 2565 patients <65 years old and 623 patients ≥65 years old (including 79 patients ≥75 years old). Mean exposure with lixisenatide 20 µg was ~30% higher in elderly than in young subjects, and the terminal half-life was prolonged by ~1.6 times. Maximum concentration (C(max)) and time to C(max) (t(max)) were comparable in both groups. Equal numbers of elderly and young subjects reported treatment-emergent adverse events, the majority of which were gastrointestinal disorders. In the pooled analysis, lixisenatide 20 µg once daily provided significant reductions in HbA1c versus placebo for all age groups. There was a similar incidence of treatment-emergent adverse events across all age groups (range: 69-73%). The incidence of symptomatic hypoglycaemia was generally comparable between lixisenatide-treated and placebo-treated patients. These data suggest that lixisenatide is effective and well tolerated in elderly and very elderly patients with type 2 diabetes mellitus.
