110-LB: Efficacy, Safety, and Appropriateness of iGlarLixi, a Fixed-Ratio Combination (FRC) in Type 2 Diabetes (T2D) in Real-World Settings: Results from the ENSURE Study

Randomized clinical trials (RCT) showed benefits of FRC of basal insulin (BI) and GLP1-RAs in terms of glycemic target, no weight gain, low risk of hypoglycemia, and gastrointestinal side effects. Real-world evidence (RWE) complements RCT to assess effectiveness and safety of drugs in clinical practice. The study evaluated the impact of iGlarLixi [once-daily FRC of basal insulin glargine 100 U/mL and GLP1-RA lixisenatide] in T2D. This was a retrospective, multicenter study, based on electronic medical records. All subjects initiating iGlarLixi in May 2018-July 2020 were analyzed. Overall, 25 centers provided data on 675 subjects with the following baseline characteristics (mean and standard deviation or proportion): age: 66.4±10.1 years, 54.2% men, T2DM duration 15.5±11.5 years, HbA1c 8.6±1.4%, and BMI 30.8±5.3 Kg/m2. Before starting iGlarLixi, 67.3% of subjects were treated with BI and 9.9% with GLP1-RA (5.5% as free combinations). Drugs associated with iGlarLixi were not only metformin and SGLT2 inhibitors, as by summary of product characteristics (SmPC); off-label combinations were found in 32.4% of patients (21.4% sulphonylureas). Effectiveness data (N=184) showed that HbA1c decreased by -0.77% [95%CI -1.00;-0.54] after 6 months and by -0.92% [95%CI -1.22;-0.62] in patients treated as by SmPC. Weight significantly decreased by 1.21 Kg. iGlarLixi dose increased by 5.14 U. Rates of blood glucose ≤70 and <54 mg/ml (N=171) were 0.26 and 0.05 events per person-month, respectively. No severe hypoglycemic events occurred. Participants discontinuing iGlarLixi within 6 months were 122 (18.1%). After discontinuation, 45.1% of patients started BI plus short acting insulin. In predominantly overweight/obese T2D people with poor metabolic control and long-lasting disease, effectiveness and safety of iGlarLixi are documented in real life, but improvements in treatment appropriateness are required.
