Background: IDegLira, a fixed-ratio combination of a basal insulin (BI), insulin degludec, and liraglutide, a glucagon-like peptide-1 receptor agonist (GLP-1), was approved by the FDA in Q4 2016 for the treatment of type 2 diabetes Mellitus (T2DM). This study describes characteristics of adult patients (pts) who initiated IDegLira in a real-world setting.
Methods: Demographic and clinical data for pts prescribed IDegLira between May and November 2017 were extracted from the Practice Fusion ambulatory care database. Pt characteristics were described for the 6-months prior to initiation. Pts were grouped by most recent antidiabetic therapy regimen in the prior 6-months.
Results: Pts prescribed IDegLira (n=388) received one of five prior therapy regimens: BI as only injectable (BI-INJ, N=88), GLP-1 as only injectable (GLP-INJ, N=47), GLP-1+insulin (GLP-INS, N=65), multiple daily insulin injections (MDI, N=35), and no injectable therapy (N-INJ, N=153). On average, IDegLira pts were 58 years old (SD 11.5); the majority (66%) between 40 and 64 years of age. Pts’ mean BMI was 35 (7.6). Mean A1C was 9.0 (1.82), with 12% below <7%, 19% between 7-7.9%, 25% between 8-8.9%, and 44% >9%. The N-INJ group had the highest mean A1C prior to initiating IDegLira (9.6), BI-INJ and GLP-INJ had intermediate means (both 9.0), and the GLP-INS and MDI groups had the lowest (8.4, 8.3). IDegLira patients previously treated with GLP-INS, MDI, and N-INJ had higher Charlson Comorbidity and Diabetes Complication Severity scores compared to patients previously treated with BI-INJ or GLP-INJ. Most prescriptions were written by PCPs (53%).
Conclusion: This analysis shows that initial use of IDegLira has been across a range of practices and clinical profiles. Most IDegLira prescribing occurred among pts on a previous injectable therapy, with those on single injectable therapy having higher A1Cs than those on multiple injectable therapies. Pts prescribed IDegLira with no injectable therapy in the prior 6 months had the highest A1C values.
