In this study, the structural and functional similarity of biosimilars of insulin glargine were evaluated. The results showed that some biosimilars had higher levels of high molecular weight species and related substances, as well as higher rates of impurity generation. The aggregation at 14 days was found to be correlated with the aggregation at 0 day and the number of months from expiry. Overall, insulin glargine biosimilars demonstrated similarity to the innovator product, but certain biosimilars exhibited low amounts of product-related variants that impacted product stability. The order of biosimilarity was Lantus((R)) > Biosimilar 2 > Biosimilar 4 > Biosimilar 1 > Biosimilar 3.
Background: A biosimilar product is expected to exhibit similar safety, efficacy, and quality as that of the approved reference product. Only a few reports of thorough evaluation of the quality of insulin glargine biosimilars are available in literature. Here, we examine the structural and functional similarity of biosimilars of insulin glargine, the first basal long-acting insulin analogue with respect to its innovator product (Lantus((R)) from Sanofi Aventis). Methods: Structural similarity was established using mass spectrometry, chromatographic, and spectroscopic techniques. Stability was compared by performing accelerated thermal stress studies. Functional similarity was established via in vitro assay. Results: Biosimilar 4 exhibited greater content of high molecular weight species (HMWs) (0.80%) and related substances (RS) (0.45 +/- 0.06%) vs others (HMWs of 0.04% and RS of 0.17%). Biosimilars 1 and 3 exhibited higher rate of impurity generation (0.78% and 0.73% per week, respectively), as compared with other drug products (0.02% to 0.43% per week). Furthermore, %aggregation at 14 days was found to statistically correlate (R-2= 0.99, root mean square error (RMSE) = 0.095) with %aggregation at 0 day (linearly) and the number of months from expiry (nonlinearly), highlighting the overpowering impact of the latter. Conclusions: While an overall structural and functional similarity was observed across insulin glargine biosimilars with respect to the innovator product, low amounts of product-related variants were seen in some biosimilars and these impact product stability. The %aggregation at 14 days exhibits statistical correlation with %aggregation at 0 day and the number of months from expiry. The order of biosimilarity was denoted as Lantus((R))> Biosimilar 2 > Biosimilar 4 > Biosimilar 1 > Biosimilar 3.
