In Vitro Biological Characterization of Recombinant Insulin Aspart from Biogenomics and Originator Insulin Aspart.
Background: Bioassays are used to identify the pharmacological activity of new or chemically unknown compounds, as well as their undesirable effect, including toxicity. Biological assays are also required to ensure the quality, safety, and efficacy of recombinant biologics to confirm its biosimilarity to its originator. In the present study, analytical similarity between the biosimilar and its innovator is established by in vitro bioassays.
Objective: The objective of this study was to show the comparative in vitro characterization of the recombinant insulin aspart from BioGenomics with its originator insulin aspart, using relevant biological assays.
Methods: In vitro assays such as receptor binding, receptor autophosphorylation, glucose uptake, and mitogenic potential were analyzed for biological characterization of BioGenomics recombinant insulin aspart (BGL-ASP) manufactured by BioGenomics Limited and NovoRapid® as the reference medicinal product (RMP) manufactured by Novo Nordisk. Insulin receptor binding was studied by a state-of-the-art method, surface plasmon resonance (SPR) for biomolecular interactions. The receptor autophosphorylation assay measures the phosphorylated insulin receptor in cell lysates. The glucose uptake assay measures the uptake of glucose by 3T3-L1 cells in the presence of insulin. Lipogenesis was studied in treated 3T3-L1 cells by detecting the accumulation of lipid droplets in the cells. Mitogenic effect was studied by cell proliferation assay using MCF-7 cells. A rabbit bioidentity test was performed by measuring the sudden decrease in blood glucose in the presence of insulin.
Results: The binding studies showed that the affinity of BGL-ASP was highly comparable to NovoRapid®. Insulin receptor autophosphorylation, glucose uptake, and lipogenesis demonstrated high similarity to the RMP. The mitogenic assay for BGL-ASP did not show any proliferative effect and was comparable to the RMP. The in vivo bioidentity test showed that the BGL-ASP is highly similar to the innovator, NovoRapid®.
Conclusion: The biological characterization studies of BGL-ASP demonstrated high binding and functional similarity to NovoRapid®.
