Evaluation of Physicochemical and Biological Stability of 36-Months-Aged SB5 (Adalimumab Biosimilar) for 4 Weeks at Room Temperature.

Abstract：

INTRODUCTION:Tumor necrosis factor (TNF-alpha) inhibitors, such as adalimumab, have shown success in treating autoimmune inflammatory diseases but are associated with substantial financial burdens to the healthcare system. Biosimilars, which are highly similar to biologic agents, offer the potential to reduce the financial burden of treatment. In the case of TNF-alpha inhibitors, they may also offer improved stability and enable prolonged use. SB5, an adalimumab biosimilar, has shown equivalent efficacy and comparable safety to its reference product in clinical trials. Currently, SB5 is approved for storage for 36 months at 2-8 °C and may be stored at room temperature (25 °C) for a maximum period of 14 days. The objective of this study was to evaluate the stability of SB5, aged to its shelf-life of 36 months, at room temperature (25 ± 2 °C) and 60 ± 5% relative humidity (RH) for a period of 4 weeks, which is longer by 14 days than that of SB5 currently approved in the European Union. METHODS:This study evaluated the stability of SB5, aged to its shelf-life of 36 months, at room temperature (25 ± 2 °C) for a period of 4 weeks. Three independent batches of 36 months-aged SB5 were stored at 25 ± 2 °C and 60 ± 5% RH for 4 weeks. Samples were tested at 0, 2, and 4 weeks. RESULTS:Color, clarity, visible particles, pH, protein concentration, and particulate matter were consistent among the batches, and all the test results met the acceptance criteria at each time point. Percent charge variance was maintained over time. Percent of high molecular weight species detected, total purity, relative binding activity by TNF-alpha, and relative potency by TNF-alpha neutralization did not change over time within each batch, and all values were within the acceptance criteria limits. CONCLUSION:SB5 aged for 36 months is physicochemically and biologically stable for 4 weeks at 25 ± 2 °C and 60 ± 5% RH, which is 2 weeks longer than the alternative storage condition as approved by the European Medicines Agency, which is at 25 °C for a period of up to 14 days.
