Effects of Vildagliptin Add-on Insulin Therapy on Nocturnal Glycemic Variations in Uncontrolled Type 2 Diabetes.

ABSTRACT:

Introduction

To investigate whether vildagliptin add-on insulin therapy improves glycemic variations in patients with uncontrolled type 2 diabetes (T2D) compared to patients with placebo therapy.

Methods

This was a 24-week, single-center, double-blind, placebo-controlled trial. Inadequately controlled T2D patients treated with insulin therapy were recruited between June 2012 and April 2013. The trial included a 2-week screening period and a 24-week randomized period. Subjects were randomly assigned to a vildagliptin add-on insulin therapy group (n = 17) or a matched placebo group (n = 16). Scheduled visits occurred at weeks 4, 8, 12, 16, 20, and 24. Continuous glucose monitoring (CGM) was performed before and at the endpoint of the study.

Results

A total of 33 subjects were admitted, with 1 patient withdrawing from the placebo group. After 24 weeks of therapy, HbA1c values were significantly reduced at the endpoint in the vildagliptin add-on group. CGM data showed that patients with vildagliptin add-on therapy had a significantly lower 24-h mean glucose concentration and mean amplitude of glycemic excursion (MAGE). At the endpoint of the study, patients in the vildagliptin add-on group had a significantly lower MAGE and standard deviation compared to the control patients during the nocturnal period (0000-0600). A severe hypoglycemic episode was not observed in either group.

Conclusion

Vildagliptin add-on therapy to insulin has the ability to improve glycemic variations, especially during the nocturnal time period, in patients with uncontrolled T2D.

Project description:INTRODUCTION:DUAL II Japan (NCT02911948) was a 26-week, phase 3a randomized, treat-to-target trial which compared the efficacy and safety of IDegLira with degludec in 210 Japanese patients with type 2 diabetes (T2D) uncontrolled on premixed or basal insulin therapy. The DUAL II Japan trial presented the opportunity for a post hoc analysis to examine the safety and efficacy of switching patients from a premixed regimen (containing both basal and bolus insulin components) to IDegLira. METHODS:Patients from DUAL II Japan were stratified according to prior insulin regimen (premixed or basal insulin). The following endpoints were assessed in this post hoc analysis by pre-trial insulin regimen: change in HbA1c, body weight, daily total insulin dose, nine-point self-measured blood glucose, and severe or blood glucose-confirmed hypoglycemia (defined as severe or plasma glucose less than 56 mg/dL). RESULTS:This post hoc analysis included 39 patients who switched from premixed insulin to IDegLira. The treatment effect in this population was independent of insulin type at baseline (premixed or basal; interaction test, P = 0.2535). In patients switching from premixed insulin to IDegLira, mean [standard deviation (SD)] HbA1c was 8.26% (0.73) at baseline and 6.68% (0.93) at week 26. Mean (SD) body weight was reduced by 1.5 (2.9) kg. At week 26, daily insulin dose was 34.2 dose steps. After 26 weeks, the mean prandial increment was smaller at all meals with IDegLira irrespective of pre-trial insulin regimen. Rate of hypoglycemic events was 2.59 events/patient-year of exposure over the 26 weeks. CONCLUSION:This post hoc study is the first to evaluate the switch from premixed insulin to IDegLira in patients with uncontrolled T2D. IDegLira initiation resulted in improved HbA1c and weight loss. This study offers insight into the effectiveness and safety of switching patients from premixed insulin therapy to IDegLira, and provides support for further investigation.

Project description:IntroductionENDURE (ClinicalTrials.gov identifier, NCT00856284), a multicenter, double-blind, active-controlled study of 2639 patients with uncontrolled type 2 diabetes mellitus (T2DM), found that metformin in combination with alogliptin (12.5 and 25 mg doses), when compared to standard add-on therapy (sulfonylurea, SU), exerted sustained antihyperglycemic effects over 2 years. This economic analysis of ENDURE aimed to quantify the relationship between increased glycemic durability and cost-effectiveness of alogliptin in the UK clinical setting, and communicate its sustained glycemic benefit in economic terms.MethodsUsing baseline characteristics and treatment effects from the ENDURE trial population, between-group cost-effectiveness analyses compared the combined use of metformin and alogliptin (MET + ALO12.5/25) in patients with inadequately controlled T2DM, as an alternative to metformin and SU (MET + SU). In scenario analyses, an intragroup cost-effectiveness analysis compared MET + ALO12.5/25 with MET + SU; a between-group cost-effectiveness analysis also compared MET + ALO12.5/25 versus MET + SU within a subpopulation of patients who achieved HbA1c control (<7.5%) at 2 years on study drug.ResultsCompared with baseline profiles of patients, combination therapies with alogliptin or SU were associated with improvements in length and quality of life and were cost-effective at established norms. Despite increased drug acquisition costs, alogliptin at 12.5 mg and 25 mg doses resulted in greater predicted lifetime quality-adjusted life year (QALY) gains with associated incremental cost-effectiveness ratios (ICERs) of £10,959/QALY and £7217/QALY compared to SU, respectively.ConclusionThe ENDURE trial and the present cost-effectiveness analysis found that the glycemic durability of alogliptin therapy was associated with improved long-term patient outcomes, QALY gains, and ICERs that were cost-effective when evaluated against standard threshold values. Alogliptin therefore represents a cost-effective treatment alternative to SU as add-on therapy to metformin in patients with poorly managed T2DM.FundingTakeda Development Centre Europe Ltd.
