certolizumab pegol is an approved drug (FDA (2008), EMA (2009))
Compound class:
Antibody
Comment: This therapeutic is a TNFα neutralising agent. Structurally it is a Fab' fragment of a TNFα-binding monoclonal antibody, which has polyethylene glycol (PEG) conjugated to a free cysteine residue in its hinge region (Cys227 of the heavy chain). Removing the Fc portion minimizes complement-dependent cytotoxicity (CDC) and antibody-dependent cell-mediated cytotoxicity (ADCC), two reactions known to cause unwanted side-effects in mAb therapies. PEGylation is used to increase the drug's half life, as Fab' fragments are normally rapidly degraded in vivo.
