ABSTRACT
INTRODUCTION: Multiple daily injection insulin regimen (MDI) represents the most intensive insulin regimen used in the management of people with type 2 diabetes (PwT2D). Its efficacy regarding glycaemic control is counterbalanced by the increased risk of hypoglycaemia, frequently observed tendency to weight gain and necessity for frequent glucose monitoring. Recent introduction of novel antidiabetic medications with pleiotropic effects reaching far beyond the reduction of glycaemia (HbA1c), such as the glucagon-like peptide 1 receptor agonist (GLP-1 RA), has significantly widened the therapeutic options available for management of T2D. Consequently, there is currently a substantial number of PwT2D for whom the MDI regimen was initiated at a time when no other options were available. Yet, in present times, these individuals could benefit from simplified insulin regimens ideally taking advantage of the beneficial effects of the novel classes of antidiabetic medications. iGlarLixi (Suliqua®) is a once-daily fixed-ratio combination of basal insulin analogue glargine 100 U/ml and a GLP-1 RA lixisenatide. METHODS: Insulin therapy DE-intensificAtion with iglarLixi (IDEAL) is a six-centre, open-label, parallel-group, active comparator, phase IV randomised controlled trial with a 24-week active treatment period examining the efficacy and safety of MDI regimen de-intensification with once-daily administration of iGlarLixi versus MDI regimen continuation in PwT2D on a backgroud therapy with metformin ± sodium-glucose cotransporter 2 inhibitor. PLANNED OUTCOMES: The primary objective is to compare the effects of MDI therapy de-intensification with iGlarLixi versus MDI regimen continuation regarding glycaemic control (HbA1c). Secondary objectives include detailed evaluation of the effects of MDI regimen de-intensification with iGlarLixi on glycaemic control using standardised continuous glucose monitoring (CGM) metrics and self-monitoring of plasma glucose. Furthermore, body weight and body composition analysis, quality of life and safety profile are evaluated. TRIAL REGISTRATION: ClinicalTrials.gov, identifier NCT04945070.
ABSTRACT
INTRODUCTION: This study aimed to investigate the sustained safety and efficacy of insulin treatment simplification with IDegLira in patients with type 2 diabetes and an HbA1c ≤ 7.5% (58 mmol/mol) during a 12-month follow-up. METHODS: Seventy-two adults with type 2 diabetes and an HbA1c ≤ 7.5% (58 mmol/mol) treated with multiple daily insulin injections (MDI) participated in the trial (age 63.8 ± 9.5 years, HbA1c 6.4 ± 0.7%, [46 ± 8 mmol/mol] body weight 92.95 ± 18.83 kg, total daily insulin dose: 43.21 ± 10.80 units; mean ± SD). Previous insulins were stopped, and once daily IDegLira was started. IDegLira was titrated by the patients to achieve a self-measured prebreakfast plasma glucose concentration of ≥5 mmol/L to ≤6 mmol/L. RESULTS: After 12 months, good glycaemic control was maintained, while body weight decreased significantly. Mean HbA1c changed to 6.2 ± 0.8% (44 ± 9 mmol/mol) (p = .109) and body weight changed by -3.89 kg to 89.06 ± 18.61 kg (p < .0001). The simplified treatment was safe and well-tolerated. Percentage of patients experiencing at least one episode of hypoglycaemia was 49% during the month before simplification and 17% during the last 3 months of the follow-up. CONCLUSIONS: Insulin treatment simplification with IDegLira in selected patients with type 2 diabetes is safe, maintains adequate glycaemic control and is associated with weight loss over 12 months.

INTRODUCTION: Type 2 diabetic patients suffering from severe hyperglycemia are often assigned a regimen involving multiple daily injections (MDI) of insulin. If the glucose toxicity resolves, the regimen can potentially be simplified, but there are no guidelines for this, and many patients are left on the MDI regimen. We aimed to prospectively examine the safety and efficacy of switching from MDI to once-daily IDegLira, a fixed-ratio combination of insulin degludec and liraglutide, in relatively well controlled (HbA1c ≤ 7.5%) subjects with type 2 diabetes on a low total daily insulin dose (TDD). METHODS: 62 adults with type 2 diabetes (baseline age 64.06 ± 10.24 years, HbA1c 6.42 ± 0.68%, BMI 33.53 ± 6.90 kg/m2, body weight 93.81 ± 19.26 kg, TDD 43.31 ± 10.99 IU/day, insulin requirement 0.47 ± 0.13 IU/kg, duration of diabetes 10.84 ± 7.50 years, mean ± SD) treated with MDI ± metformin were enrolled in our study. Previous insulins were stopped and once-daily IDegLira was started. IDegLira was titrated by the patients to achieve a self-measured pre-breakfast blood glucose concentration of < 6 mmol/L. RESULTS: After a mean follow-up period of 99.2 days, mean HbA1c had decreased by 0.30% to 6.12 ± 0.65% (p < 0.0001), body weight had decreased by 3.11 kg to 90.70 ± 19.12 kg (p < 0.0001), and BMI had reduced to 32.39 ± 6.71 kg/m2 (p < 0.0001). After 3 months of treatment, the mean dose of IDegLira was 20.76 ± 6.60 units and the mean insulin requirement had decreased to 0.23 ± 0.08 IU/kg. IDegLira ± metformin combination therapy was found to be safe and generally well tolerated. During the month before the baseline visit, 28 patients (45%) had at least one episode of documented or symptomatic hypoglycemia, while only 6 (9.67%) patients reported a total of 13 documented episodes during the follow-up. CONCLUSION: In everyday clinical practice, switching from low-dose MDI to IDegLira in patients with well-controlled type 2 diabetes is safe, may result in weight loss and similar or better glycemic control, and substantially reduces the insulin requirement. Simplifying complex treatment regimens decreases treatment burden and may improve adherence to therapy. CLINICAL TRIAL NUMBER: NCT04020445.
