Comparison of acarbose and voglibose in diabetes patients who are inadequately controlled with basal insulin treatment: randomized, parallel, open-label, active-controlled study.

ABSTRACT: We studied the efficacy and safety of acarbose in comparison with voglibose in type 2 diabetes patients whose blood glucose levels were inadequately controlled with basal insulin alone or in combination with metformin (or a sulfonylurea). This study was a 24-week prospective, open-label, randomized, active-controlled multi-center study. Participants were randomized to receive either acarbose (n=59, 300 mg/day) or voglibose (n=62, 0.9 mg/day). The mean HbA1c at week 24 was significantly decreased approximately 0.7% from baseline in both acarbose (from 8.43% ± 0.71% to 7.71% ± 0.93%) and voglibose groups (from 8.38% ± 0.73% to 7.68% ± 0.94%). The mean fasting plasma glucose level and self-monitoring of blood glucose data from 1 hr before and after each meal were significantly decreased at week 24 in comparison to baseline in both groups. The levels 1 hr after dinner at week 24 were significantly decreased in the acarbose group (from 233.54 ± 69.38 to 176.80 ± 46.63 mg/dL) compared with the voglibose group (from 224.18 ± 70.07 to 193.01 ± 55.39 mg/dL). In conclusion, both acarbose and voglibose are efficacious and safe in patients with type 2 diabetes who are inadequately controlled with basal insulin. (ClinicalTrials.gov number, NCT00970528).

Project description:Aims/introductionThe present study was to compare the efficacy and safety of subject-driven and investigator-driven titration of biphasic insulin aspart 30 (BIAsp 30) twice daily (BID).Materials and methodsIn this 20-week, randomized, open-label, two-group parallel, multicenter trial, Chinese patients with type 2 diabetes inadequately controlled by premixed/self-mixed human insulin were randomized 1:1 to subject-driven or investigator-driven titration of BIAsp 30 BID, in combination with metformin and/or α-glucosidase inhibitors. Dose adjustment was decided by patients in the subject-driven group after training, and by investigators in the investigator-driven group.ResultsEligible adults (n = 344) were randomized in the study. The estimated glycated hemoglobin (HbA1c) reduction was 14.5 mmol/mol (1.33%) in the subject-driven group and 14.3 mmol/mol (1.31%) in the investigator-driven group. Non-inferiority of subject-titration vs investigator-titration in reducing HbA1c was confirmed, with estimated treatment difference -0.26 mmol/mol (95% confidence interval -2.05, 1.53) (-0.02%, 95% confidence interval -0.19, 0.14). Fasting plasma glucose, postprandial glucose increment and self-measured plasma glucose were improved in both groups without statistically significant differences. One severe hypoglycemic event was experienced by one subject in each group. A similar rate of nocturnal hypoglycemia (events/patient-year) was reported in the subject-driven (1.10) and investigator-driven (1.32) groups. There were 64.5 and 58.1% patients achieving HbA1c <53.0 mmol/mol (7.0%), and 51.2 and 45.9% patients achieving the HbA1c target without confirmed hypoglycemia throughout the trial in the subject-driven and investigator-driven groups, respectively.ConclusionsSubject-titration of BIAsp 30 BID was as efficacious and well-tolerated as investigator-titration. The present study supported patients to self-titrate BIAsp 30 BID under physicians' supervision.

Project description:IntroductionIDegLira is a once-daily combination of insulin degludec (IDeg) and liraglutide. Trials directly comparing IDegLira with alternative strategies for intensifying basal insulin are ongoing. While awaiting results, this analysis compared indirectly how different strategies affected glycated hemoglobin (HbA1c) and other outcomes.MethodsA pooled analysis of five completed Novo Nordisk randomized clinical trials in patients with type 2 diabetes inadequately controlled on basal insulin was used to compare indirectly IDegLira (N = 199) with: addition of liraglutide to basal insulin (N = 225) [glucagon-like peptide-1 receptor agonist (GLP-1RA) add-on strategy]; basal-bolus (BB) insulin [insulin glargine (IGlar) + insulin aspart] (N = 56); or up-titration of IGlar (N = 329). A supplementary analysis was performed with the BB arm including patients who received IGlar or IDeg as basal insulin in the relevant trial (N = 210). All trials had comparable inclusion/exclusion criteria and baseline characteristics. Individual patient-level data were analyzed using multivariable statistical models with potential baseline heterogeneity accounted for using explanatory variables.ResultsAt end of study, differences between IDegLira and BB or up-titrated IGlar, respectively, were as follows: reduction in HbA1c -0.30%, 95% confidence interval (-0.58; -0.01) and -0.65% (-0.83; -0.47); change in body weight -6.89 kg (-7.92; -5.86) and -4.04 kg (-4.69; -3.40) all in favor of IDegLira. Confirmed hypoglycemia rate was 122.8 (90.7; 166.1), 1060.8 (680.2; 1654.4), and 286.1 (231.1; 354.1) events/100 patient-years for IDegLira, BB, and up-titrated IGlar, respectively. Odds ratios for achieving HbA1c <7.0%, <7.0% without hypoglycemia, and <7.0% without hypoglycemia and no weight gain were greater with IDegLira versus up-titrated IGlar. The supplementary analysis yielded similar results to the main analysis. Results with IDegLira were similar to those for the 'GLP-1RA add-on' arm.ConclusionThese results suggest that IDegLira may be more effective, with lower hypoglycemia rates and less weight gain, than up-titrated basal insulin or BB in patients uncontrolled on basal insulin.

Project description:INTRODUCTION:This study aimed to determine, in close to real-life conditions, the efficacy and safety of switching from any basal insulin to insulin glargine 300 U/mL (Gla-300) in patients with uncontrolled type 2 diabetes (T2D). METHODS:This was an interventional, multicenter, single-arm, prospective study with a 24-week treatment phase. Adult patients with T2D treated with basal insulin with or without other antidiabetics, HbA1c > 7.5%, and fasting self-monitored blood glucose (F-SMBG) > 130 mg/dL (mean of three measures) at baseline were included. Insulin dose was titrated to reach F-SMBG 90-130 mg/dL. Efficacy and safety were assessed at 12 weeks (W12) and 24 weeks (W24). The main outcome parameter was HbA1c change between baseline and W24. Safety parameters included self-reported hypoglycemia (any type). Patients' satisfaction with the treatment was assessed by the Diabetes Treatment Satisfaction Questionnaire (DTSQ). RESULTS:A total of 140 patients were included and 137 were treated. Mean HbA1c decreased from 8.64% at baseline to 8.14% at W12 (mean difference [95% CI] - 0.51% [- 0.64; - 0.38]) and 8.01% at W24 (- 0.64% [- 0.81; - 0.46]). Target F-SMBG was reached in 35.0% of the patients at W12 and 38.4% at W24. The percentages of patients reaching HbA1c levels < 7.0%, < 7.5%, and < 8.0% at W24 were 11.4%, 29.5%, and 50.8%, respectively, while only 31.6% had an HbA1c value < 8.0% at baseline. HbA1c reduction was greater in patients with higher baseline levels. During the treatment phase, 46.0% of the participants had at least one hypoglycemia event; 31.4% documented symptomatic hypoglycemia, 2.2% severe hypoglycemia, and 12.2% nocturnal hypoglycemia. Treatment satisfaction increased by 20% between baseline and W24. CONCLUSION:These data, derived from close to real-life practice in France, confirm the reassuring results of randomized trials on the efficacy and safety of Gla-300.

Project description:IntroductionWe comprehensively evaluated the effects of combination therapy with insulin glargine and the incretin-based drugs lixisenatide or vildagliptin in Japanese patients with type 2 diabetes.MethodsIn this 12-week, randomized, open-label, parallel-group, multicenter study (GLP-ONE Kobe), the incretin-based drug sitagliptin was randomly switched to lixisenatide (20 μg/day, n = 18) or vildagliptin (100 mg/day, n = 20) in patients with inadequate glycemic control despite combination therapy with insulin glargine and sitagliptin. The dose of insulin glargine was titrated after the switch to maintain fasting blood glucose at approximately 110 mg/dL. The primary end points of the study were the change in glycosylated hemoglobin (HbA1c) level between before and 12 weeks after the treatment switch, the proportion of patients achieving an HbA1c level below 7.0%, and the postprandial increase in glucose concentration as assessed by self-monitoring of blood glucose.ResultsThe change in HbA1c level from baseline to 12 weeks did not differ significantly between the lixisenatide and vildagliptin groups (- 0.6 ± 0.7% and - 0.6 ± 1.2%, respectively, P = 0.920). Neither the proportion of patients achieving an HbA1c level below 7.0% nor the postprandial increase in glucose concentration was different between two groups. Body weight and serum low density lipoprotein (LDL) cholesterol level decreased significantly in the lixisenatide and vildagliptin groups, respectively. Both drugs were associated with mild gastrointestinal symptoms but not with severe hypoglycemia. Vildagliptin was associated with elevation of serum aspartate transaminase. Treatment satisfaction as assessed with the Diabetes Treatment Satisfaction Questionnaire did not differ significantly between the two groups.ConclusionThe combinations of basal insulin and either lixisenatide or vildagliptin have similar efficacies with regard to improvement of glycemic control.Trial registrationThis trial has been registered with UMIN (No. 000010769).
