Certolizumab pegol  (CDP870, tradename Cimzia) is a therapeutic monoclonal antibody to tumor necrosis factor alpha (TNF-α), for the treatment of Crohn's disease and rheumatoid arthritis, manufactured by UCB.
Method of action
Polyethylene glycol does not cross the placenta, so it should be safe in pregnancy.
Positive results have been demonstrated in two phase III trials (PRECiSE 1 and 2) of certolizumab pegol versus placebo in moderate to severe active Crohn's disease. In addition, data from both trials suggest it is well tolerated. As yet its efficacy has not been directly compared to other anti-TNF-α agents.
In 2013, a phase 3 double blind randomized placebo-controlled study found significantly positive result in patient self-reported questionnaires, with rapid improvement of function and pain reduction. 
On April 22, 2008, the U.S. Food and Drug Administration (FDA) approved Cimzia for use in the United States for the treatment of Crohn's disease in people who did not respond sufficiently or adequately to standard therapy.
On June 26, 2009, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMEA) issued a positive opinion recommending that the European Commission grant a marketing authorisation for Cimzia for the treatment of rheumatoid arthritis only - the CHMP refused approval for the treatment of Crohn's disease. The marketing authorisation was granted to UCB Pharma SA on October 1, 2009.
