Immunogenicity, efficacy, and safety of biosimilar insulin glargine (Gan & Lee glargine) compared with originator insulin glargine (Lantus?) in patients with type 2 diabetes after 26 weeks' treatment: A randomized open label study
Diabetes, Obesity and Metabolism(2024)
摘要
AimTo evaluate the equivalence of immunogenicity, safety and efficacy of Gan & Lee (GL) Glargine (Basalin (R); Gan & Lee Pharmaceutical) with that of the reference product (Lantus (R)) in adult participants with type 2 diabetes mellitus.MethodsThis was a phase 3, multicenter, open-label, equivalence trial conducted across 57 sites. In total, 567 participants with type 2 diabetes mellitus were randomized in a 1:1 ratio to undergo treatment with either GL Glargine or Lantus (R) for 26 weeks. The primary endpoint was the proportion of participants in each treatment arm who manifested treatment-induced anti-insulin antibodies (AIA). Secondary endpoints included efficacy and safety metrics, changes in glycated haemoglobin levels, and a comparative assessment of adverse events. Results were analysed using an equivalence test comparing the limits of the 90% confidence interval (CI) for treatment-induced AIA development to the prespecified margins.ResultsThe percentages of participants positive for treatment-induced glycated haemoglobin by week 26 were similar between the GL Glargine (19.2%) and Lantus (R) (21.3%) treatment groups, with a treatment difference of -2.1 percentage points and a 90% CI (-7.6%, 3.5%) (predefined similarity margins: -10.7%, 10.7%). The difference in glycated haemoglobin was -0.08% (90% CI, -0.23, 0.06). The overall percentage of participants with any treatment-emergent adverse events was similar between the GL Glargine (80.1%) and Lantus (R) (81.6%) treatment groups.ConclusionsGL Glargine was similar to Lantus (R) in terms of immunogenicity, efficacy, and safety, based on the current study.
