Glycemic Control Among Patients Newly Prescribed IDegLira Across Prior Therapy Group in US Real-World Practice.

Abstract

IntroductionIDegLira is a fixed-ratio combination of insulin degludec and liraglutide indicated for the treatment of type 2 diabetes (T2D). We report the first real-world study describing change in glycated hemoglobin (HbA1c) among US patients who initiated IDegLira. The aim of the study was to observe and describe changes in glycemic control and weight in patients initiating IDegLira in real-world clinical practice.MethodsPatients in the Practice Fusion electronic medical record database who initiated treatment with IDegLira between March 2017 and June 2018 were identified (n = 1384). To be included in the analyses, the study population needed to meet age, time in database pre- and post-initiation, and availability of HbA1c data at baseline and follow-up requirements. Data were analyzed according to baseline therapy subgroups and whether patients were intensifying (primary analysis group) or simplifying (secondary analysis group) their diabetes treatment. Changes in clinical outcomes from baseline were evaluated by paired t tests and linear regression.ResultsThe overall study population comprised 296 patients, of whom 206 were included in the primary analysis group and 90 were included in the secondary analysis group. In the adjusted analyses, there was a reduction in HbA1c of – 1.1% in the primary analysis group, with the HbA1c reduction in all prior therapy groups ranging from – 0.8% for those previously on basal insulin to – 1.0% for those previously on non-injectable therapy (p < 0.0001 for all). In a similar adjusted analysis, there was a statistically significant but small (1.0 lb/0.45 kg) change in weight in the primary analysis group. In the secondary analysis, patients previously on more than one injection daily switched to a more simplified therapy without compromising on glycemic control (HbA1c change of − 0.16%).ConclusionConsistent with previous real-world studies, IDegLira lowered HbA1c across different background prior glucose-lowering therapies, with minimal impact on weight.
