Titratable fixed-ratio combination of basal insulin plus a glucagon-like peptide-1 receptor agonist: A novel, simplified alternative to premix insulin for type 2 diabetes.

ABSTRACT: Despite novel therapeutic options, many people with type 2 diabetes (T2D) do not achieve their HbA1c targets. Given the progressive nature of T2D, many individuals not controlled with oral therapy will require advancement to injectable therapy using either a glucagon-like peptide-1 receptor agonist (GLP-1 RA), recently recommended as a first option, or traditionally a basal insulin. However, premix insulins remain frequently used, either as initial injectable therapy or as intensification from basal insulin. Premix insulin injections can potentially provide significant glycaemic improvements to basal insulin but at the expense of increased hypoglycaemia and weight gain and the need for multiple daily doses, which may affect treatment adherence. Real-world evidence suggests that glycaemic control often remains suboptimal with premix insulins. Fixed-ratio combinations (FRCs) of basal insulin and GLP-1 RAs provide a novel alternative to premix insulin for therapy intensification. While no direct comparisons between premix insulins and FRCs are available, results from meta-analyses suggest that FRCs may offer better HbA1c reductions, a lower risk of hypoglycaemia and less weight gain compared with premix insulin in a simplified treatment regimen. A head-to-head trial of T2D treatment intensification with premix insulin and a FRC of basal insulin plus a GLP-1 RA is currently in progress, which should help to clarify the outcomes for each treatment option. This review discusses the unmet needs of people with T2D treated with premix insulin and provides evidence supporting FRCs of basal insulin and GLP-1 RAs as an alternative treatment option.

Project description:ObjectiveThis study assessed the efficacy and safety of LixiLan, a fixed-ratio, titratable, combination of 2 units insulin glargine (Gla-100) and 1 μg lixisenatide administered once daily via a single pen, versus Gla-100 in insulin-naïve type 2 diabetes on metformin.Research design and methodsParticipants were randomized to once-daily LixiLan (n = 161) or Gla-100 (n = 162) for 24 weeks, while continuing metformin. LixiLan and Gla-100 were started at 10 units/5 μg and 10 units, respectively, and titrated based on the Gla-100 requirement according to fasting plasma glucose levels. The primary objective was to test noninferiority (upper bound of the 95% CI ≤0.4%) of LixiLan in reducing HbA1c; if met, statistical superiority was tested. Secondary objectives included body weight changes, hypoglycemia, and safety.ResultsBaseline characteristics (mean age 57 years, diabetes duration 6-7 years, BMI 32 kg/m(2)) were similar between groups. At week 24, mean HbA1c was reduced from 8.0% (64 mmol/mol) at baseline to 6.3% (45 mmol/mol) and 6.5% (48 mmol/mol) with LixiLan and Gla-100, respectively, establishing statistical noninferiority and superiority of LixiLan (least-squared mean [95% CI] difference: -0.17% [-0.31, -0.04] {-1.9 mmol/mol [-3.4, -0.4]}; P = 0.01). HbA1c <7.0% (<53 mmol/mol) was achieved in 84% and 78% of participants (nonsignificant), respectively. LixiLan improved 2-h postmeal plasma glucose versus Gla-100 (least-squared mean difference: -3.17 mmol/L [-57 mg/dL]; P < 0.0001). Body weight was reduced with LixiLan (-1 kg) and increased with Gla-100 (+0.5 kg; P < 0.0001), with no increase in hypoglycemic events (∼25% in each group). The incidence of nausea (7.5%) and vomiting (2.5%) was low with LixiLan.ConclusionsLixiLan achieved statistically significant reductions to near-normal HbA1c levels with weight loss and no increased hypoglycemic risk, compared with insulin glargine alone, and a low incidence of gastrointestinal adverse events in type 2 diabetes inadequately controlled on metformin.

Project description:IntroductionTo date, there have been few head-to-head comparisons between semaglutide once-weekly (OW) and short-acting meal-time insulin in participants with type 2 diabetes (T2D) treated with basal insulin and requiring treatment intensification. This indirect comparison evaluated the effects of these regimens on glycated haemoglobin (HbA1c), body weight, hypoglycaemia, and other clinically relevant outcomes.MethodsA post-hoc, unanchored, individual participant data meta-analysis was conducted on the basis of data from single treatment arms in the SUSTAIN 5 and DUAL 7 trials. Semaglutide 0.5 mg OW and 1.0 mg OW plus basal insulin were compared with an optimised (treat-to-target) basal-bolus regimen of insulin glargine and insulin aspart over 26 weeks, using regression adjustment to account for baseline differences between the trials.ResultsOver 26 weeks, semaglutide 1.0 mg OW plus basal insulin reduced mean HbA1c by significantly more than the basal-bolus regimen (treatment difference: - 0.36%; p = 0.003), while semaglutide 0.5 mg OW plus basal insulin was comparable with basal-bolus insulin (treatment difference: 0.08%, p = 0.53). Both doses of semaglutide were associated with significant weight loss relative to insulin intensification (treatment differences: 6.8-9.4 kg; p < 0.001). At both doses, semaglutide intensification required less basal insulin per day than bolus intensification, and more participants on semaglutide met HbA1c targets of < 7.0% and ≤ 6.5% without hypoglycaemia or weight gain (odds ratio [OR] for < 7.0%, 21.9; OR for ≤ 6.5%, 16.2; both p < 0.001).ConclusionsIn T2D uncontrolled by basal insulin, intensification with semaglutide 1.0 mg OW was associated with better glycaemic control, weight loss, and reduced hypoglycaemia versus a basal-bolus regimen, while limiting the treatment burden associated with frequent injections. Clinicians could consider treatment intensification with semaglutide when T2D is uncontrolled by basal insulin, especially when weight management is a priority. Effective glycaemic control coupled with weight management can alleviate the burden of diabetes-associated complications.
