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

Een shown to be similar to adalimumab with respect to binding to a panel of Fc receptors, including FccRIa, FccRIIa, FccRIIIa (158V) (with and without TNFa), and FccRIIIa (158F). Importantly, effector function activation (ADCC and CDC) was also demonstrated to be similar between ABP 501 and adalimumab using highly sensitive methods. The ADCC and CDC methods have been demonstrated to be sensitive t

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
N of the mAb were shown to be able to discriminate a thermally degraded sample (data not shown), demonstrating that the utilized assays are sensitive to detect differences in activity, if they did exist. It is well established that IgG1 mAbs are efficient mediators of effector function, and are able to bind to many of the known FccRs. A sensitive comparison of these Fcdependent activities is impor
