Abstract
Introduction: Improved understanding of the pathogenesis of rheumatoid arthritis (RA), and subsequent development of targeted therapies, have greatly advanced the management of this chronic inflammatory disease. The aim of treatment is a state of clinical remission. Certolizumab pegol (CZP) is a novel pegylated TNF alpha inhibitor (TNFi) therapy and is the focus of this review.Areas covered: CZP is different from other TNFi as it contains a polyethylene glycol (PEG) moiety, and lacks the constant fragment (Fc) of immunoglobulin; therefore it does not activate complement. In this review in addition to clinical efficacy of CZP, effects on radiographic and patient-reported outcomes, are discussed. Adverse event data from clinical trials and extension studies are also reviewed.Expert opinion: The addition of novel TNFi therapies to treat RA is welcomed. As well as displaying clinical efficacy, there is evidence to suggest that CZP has unique characteristics, including reduced transfer across the placenta and reduced frequency of injection site reactions. Furthermore, randomised controlled trials (RCTs) of CZP have demonstrated rapid improvements in workplace and home productivity in patients contributing to reducing the significant socioeconomic burden of RA.
