RESUMEN
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.
RESUMEN
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.
