Assessment of the bioactivity of adalimumab should include assessment of multiple in vitro endpoints (NFjB-dependent and NFjB-independent) and should include binding to both soluble and transmembrane TNFa. ABP 501 has been shown to be similar to adalimumab in its ability to neutralize TNFa-induced caspase activation, chemokine production, and cytotoxicity, functions inclusive of both NFjB-dependen
To mediate ADCC in vitro [9, 17, 23]. Although the contribution of ADCC activity to clinical efficacy is unclear, it is important to characterize all activities of the candidate mAb, especially those that can be affected by differences in post-translational modifications, such as glycosylation. The ability of ABP 501 to induce ADCC was assessed using MT-3 cells as target cells, and NK-92M1 cells s

Onstrated since all of the ABP 501 lots fell within the quality range established based on the adalimumab (US) lots tested. Another mechanism for inducing cell death is the induction of CDC in cells expressing mbTNFa. A comparison of the CDC activity of ABP 501 to that of adalimumab (US) and adalimumab (EU) using MT-3 cells as target cells was conducted. Mean (three independent experiments) percen
