EFFICACY AND SAFETY OF IDEGLIRA IN OLDER PATIENTS WITH TYPE 2 DIABETES.

OBJECTIVE: The efficacy and safety of insulin degludec/liraglutide (IDegLira) in older patients has not yet been reported. This analysis aimed to evaluate the efficacy and safety of IDegLira in patients aged ≥65 years. METHODS: A post hoc analysis compared results of patients aged ≥65 versus <65 years from DUAL II, III, and V. These were 26-week, phase 3, randomized, twoarm parallel, treat-to-target trials in patients already taking injectable glucose-lowering agents. We evaluated 311 patients aged <65 and 87 patients aged ≥65 years from DUAL II, 326 patients <65 years and 112 patients ≥65 years from DUAL III, and 412 patients <65 years and 145 patients ≥65 years from DUAL V. Patients were randomized to IDegLira or insulin degludec (DUAL II), IDegLira or unchanged glucagon-like peptide 1-receptor agonist (GLP-1RA) (DUAL III), or IDegLira or IGlar U100 (DUAL V). RESULTS: In patients ≥65 years, hemoglobin A1C decreased to a greater extent with IDegLira than with comparators (estimated treatment differences, -1.0% [-1.5; -0.6]95% confidence interval [CI], -0.8% [-1.0; -0.5]95% CI, and -0.9% [-1.3; -0.6]95%CI) for DUAL II, V, and III, respectively; all P<.001). These mirrored results of patients <65 years of age. Hypoglycemia rates were lower with IDegLira versus basal insulin and higher versus unchanged GLP-1RA (estimated rate ratios, 0.5 [0.2; 1.6]95% CI [ P = .242]; 0.3 [0.1; 0.5]95% CI [ P<.001], and 11.8 [3.3; 42.8]95% CI [ P<.001] for DUAL II, V, and III, respectively). CONCLUSION: Patients aged ≥65 years on basal insulin or GLP-1RA can improve glycemic control with IDegLira, and it is well tolerated overall.
