SPIRIT: Assessing Clinical Parameters Associated with Using IDegLira in Patients with Type 2 Diabetes in a Real-World Setting in Colombia

Introduction: Insulin degludec/liraglutide (IDegLira) is a fixed-ratio combination of insulin degludec (a basal insulin) and liraglutide (a glucagon-like peptide-1 receptor agonist [GLP-1RA]). This study aimed to investigate clinical outcomes in people with type 2 diabetes mellitus (T2DM) after initiating IDegLira treatment in a real-world setting in Colombia. Methods: SPIRIT is a non-interventional, single-arm, retrospective chart review study to assess clinical outcomes in people with T2DM. Participating patients were switched from a treatment regimen of basal insulin (with or without oral antidiabetics [OADs]) and started on treatment with IDegLira a minimum of 26 ± 6 weeks before the data collection start date. Data were collected from the medical records of 175 patients in ten clinical centers across Colombia. Results: Compared with baseline, there was a significant reduction in glycated hemoglobin (HbA1c) (1.3%; 95% confidence interval [CI] − 1.6 to − 1.0; p < 0.0001) after 26 ± 6 weeks of follow-up. The mean HbA1c at baseline and at the end of the study was 9.1% and 7.8%, respectively. In addition, IDegLira significantly reduced absolute body weight by 1 kg (95% CI − 1.5 to − 0.5; p < 0.0001), from a mean of 76.1 kg at baseline to 75.1 kg after follow-up. The mean IDegLira dose at the end of the study was 21.3 U, and no severe hypoglycemic events were observed during the follow-up period. Conclusion: In real-world practice, initiating IDegLira in patients with T2DM previously treated with basal insulin (± OAD) was associated with improved glycemic control, reduced body weight and reduced risk of hypoglycemia.
