dc.description.abstract | The currently used Tumor Nectosis Factor (TNIF)-alpha blockers such as infliximab, adalimumab and etanercept have Fc regions of the human IgG1 subtype have advantages in terms of in vivo half-life, however these could raise potential concerns for unwanted effector-mediated effects, such as antibody dependent cellular cytotoxicity (ADCC) or complement-dependent cytotoxicity (CDC). To address this issue, we constructed a novel hybrid protein with decreased ADCC and CDC potentials by fusing the TNF receptor to a hybrid Fc (hyFc) containing CH2 and CH3 regions of IgG4 and highly flexible hinge regions of IgD which neither has ADCC and CDC activities. The resulting fusion protein, TNFR-hyFc, was over-expressed in CHO cells. For use as a pre-clinical material in pharmacology, PK and toxicological evaluations were carried out for biochemical characterization which was then compared with etanercept that has similarity in structure. Amino acid composition analysis and peptide mapping showed that the expressed TNFR-hyFc matched the theoretical composition derived from the DNA sequence. Matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) showed that TNFR-hyFc is 2.9 kDa larger than etanercept. MALDI-TOF after removal of N-glycans by PNGase treatment showed that TNFR-hyFc is 3.9 kDa larger than etanercept. Isoelectric focusing and monosaccharide analysis showed that TNFR-hyFc is slightly more acidic than etanercept. N-terminal amino acid sequencing showed that N-terminal heterogeneity is present in both TNFR-hyFc and etanercept, although the ratios are somewhat different. Glycan analysis showed that the main glycan form is bi-antennary, similar to etanercept. (C) 2012 Elsevier Inc. All rights reserved. | - |
