Clinical study of repaglinide efficacy and safety in type 2 diabetes mellitus patients with blood glucose levels inadequately controlled by sitagliptin.

ABSTRACT:

Aims/introduction

The aim of the present study was to evaluate the long-term efficacy and safety of adding repaglinide in patients with type 2 diabetes mellitus whose blood glucose levels were not sufficiently controlled by treatment with a dipeptidyl peptidase-4 inhibitor, sitagliptin, in addition to diet and exercise therapies.

Materials and methods

This was a multicenter, uncontrolled, dose-titration study with a treatment period of 52 weeks. The primary end-point was the change in glycated hemoglobin levels from baseline.

Results

The glycated hemoglobin level was 7.43 ± 0.57% (mean ± standard deviation) at baseline, and decreased to 6.93 ± 0.91% at the end of the study. The mean changes in glycated hemoglobin levels at 4 weeks and at the end of the study were -0.44 ± 0.28% and -0.50 ± 0.82%, respectively. The glycated hemoglobin-lowering effect was maintained for 52 weeks. The rate of adverse events was 86.0% (86/100), and there were 352 adverse events. The rate of adverse drug reactions was 21.0% (21/100). Hypoglycemia was reported in 5.0% (5/100) of patients, but there was no incidence of 'major hypoglycemia'.

Conclusions

Combination therapy with repaglinide and sitagliptin was considered effective for a long term without clinical safety problems in patients with type 2 diabetes mellitus.

Project description:IntroductionThe efficacy and safety of taspoglutide, a long-acting human glucagon-like peptide-1 analog, were compared with sitagliptin or placebo, as adjunct to metformin, in patients with inadequately controlled type 2 diabetes.MethodsIn this randomized, double-blind, double-dummy, parallel-group trial, patients were randomized to taspoglutide 10 mg once weekly (QW), 20 mg QW, 100 mg sitagliptin once daily (QD), or placebo for 24 weeks, followed by 28-week short-term and 104-week long-term extension periods. The primary endpoint was change in glycosylated hemoglobin (HbA(1c)) after 24 weeks.ResultsIn this study, 666 patients (baseline HbA(1c), 7.96% [SD, 0.87]; fasting plasma glucose, 9.61 mmol/L [2.56]; body weight, 92.4 kg [19.3]) were randomized to taspoglutide 10 mg QW (n = 190), 20 mg QW (n = 198), 100 mg sitagliptin QD (n = 185), or placebo (n = 93) for 24 weeks. After 24 weeks, least squares mean (SE) HbA(1c) reductions were greater with taspoglutide 10 mg (-1.23% [0.06]) and 20 mg (-1.30% [0.06]) versus sitagliptin (-0.89% [0.06]) or placebo (-0.10% [0.08]). Mean treatment differences with taspoglutide 10 mg and 20 mg were -0.34 (95% confidence intervals [CI]: -0.49, -0.19) and -0.41 (-0.56, -0.26) versus sitagliptin; and -1.13 (-1.31, -0.95) and -1.20 (-1.38, -1.02) versus placebo. Weight loss was greater with taspoglutide 10 mg (-1.8 kg [0.3]) and 20 mg (-2.6 kg [0.3]) than sitagliptin (-0.9 kg [0.3]) or placebo (-0.5 kg [0.4]). Effects on HbA(1c) and weight loss continued through 52 weeks of treatment. No cases of severe hypoglycemia occurred with any active treatment. Gastrointestinal adverse events, and allergic and injection-site reactions were higher in the taspoglutide groups, causing higher discontinuation rates. Anti-taspoglutide antibodies were confirmed in 46% of patients.ConclusionTaspoglutide demonstrated better efficacy on glycemic control and weight loss than sitagliptin, but a high incidence of adverse events led to high discontinuation rates. The safety profile of taspoglutide in this trial was similar to other trials in the clinical program, and led to the discontinuation of dosing.

Project description:IntroductionSulfonylureas (SU) are commonly used antihyperglycemic agents. VERTIS CV was the cardiovascular outcome study for the sodium-glucose cotransporter 2 inhibitor ertugliflozin. Enrollment of patients in VERTIS CV occurred in two sequential cohorts (Cohort 1 and Cohort 2).MethodsThis substudy assessed the efficacy and safety of adding ertugliflozin to SU monotherapy. The primary endpoint was the change in HbA1c from baseline at 18 weeks.ResultsAmong the 8246 patients who were randomized in VERTIS CV, 157 patients in Cohort 1 and 135 patients in Cohort 2 were on SU monotherapy at baseline. In the prespecified analysis (Cohort 1 only), the least squares (LS) mean HbA1c change from baseline for placebo, ertugliflozin 5 mg, and ertugliflozin 15 mg was - 0.56%, - 0.91%, and - 0.78%, respectively (placebo-adjusted LS mean [95% CI] change: - 0.35% [- 0.72%, 0.02%]; - 0.22% [- 0.60%, 0.16%] for ertugliflozin 5 and 15 mg, respectively; p > 0.05 for both). In a post-hoc analysis that included Cohorts 1 and 2 (N = 292), the LS mean HbA1c change from baseline at week 18 for placebo, ertugliflozin 5 mg, and ertugliflozin 15 mg was - 0.31%, - 0.77%, and - 0.68%, respectively (placebo-adjusted change: - 0.46% [- 0.73%, - 0.18%]; - 0.37% [- 0.66%, - 0.09%]; p = 0.001 and 0.01 for ertugliflozin 5 and 15 mg, respectively). In Cohort 1, adverse events were reported in 45.8%, 47.3%, and 25.9% of patients with placebo, ertugliflozin 5 mg, and ertugliflozin 15 mg. The incidence rates of symptomatic hypoglycemia were 0.0%, 5.5%, and 3.7%, respectively, with no cases of severe hypoglycemia. The safety profile was similar for Cohorts 1 and 2 combined.ConclusionThe addition of ertugliflozin to SU monotherapy reduced HbA1c but did not result in significant placebo-adjusted reductions from baseline according to the prespecified primary analysis (n = 157); however, in a post-hoc analysis with a larger patient population (n = 292), significant and clinically relevant HbA1c reductions were observed. Ertugliflozin was generally well tolerated.Trial registrationClinicalTrials.gov identifier: NCT01986881.
