Treatment of Crohn's disease with certolizumab pegol.
Biologic therapies have revolutionized the treatment of Crohn's disease (CD). Targeting TNF-alpha with monoclonal antibodies has changed the therapeutic landscape for tackling refractory and complicated CD. Intravenous use of infliximab, a chimeric monoclonal antibody to TNF-alpha is, however, limited by the occurrence of adverse events, infusion reactions, infectious complications, aggravation of heart failure, the occurrence of neurological demyelinating conditions and induction of rare malignancies. The incremental development of next-generation TNF-alpha antibodies and binding proteins through antibody-engineering techniques has followed, with the aim of producing efficacious drugs that are less expensive to produce, have a convenient route of administration and have fewer side effects. Certolizumab pegol (CDP870, Cimzia) is an engineered humanized anti-TNF-alpha antibody Fab fragment that minimizes the protein component and is conjugated to polyethylene glycol. Clinical studies have demonstrated efficacy in the treatment of moderate-to-severe active CD. Reported adverse events in the clinical trial program have been largely of mild-to-moderate severity, and occurred at similar frequencies in the active-treatment and placebo groups. Certolizumab pegol will be a useful addition to the armamentarium of biologic agents that can be used for the long-term treatment of CD.[1]References
