Certolizumab pegol, sold under the brand name Cimzia, is a medication used to treat Crohn's disease, rheumatoid arthritis, psoriatic arthritis, plaque psoriasis, and ankylosing spondylitis.[1] It is given by injection under the skin.[3]

Common side effects include infections such as abscesses, low white blood cells, nausea, headache, numbness, high blood pressure, liver inflammation, rash, and pain at the site of injection.[2] Other side effects may include cancer, heart failure, and angioedema.[3] It is a fragment of a monoclonal antibody that binds to tumor necrosis factor alpha (TNF-α).[3]

Certolizumab pegol was approved for medical use in the United States in 2008 and Europe in 2009.[1][2] It is on the World Health Organization's List of Essential Medicines as an alternative to adalimumab.[4] In the United Kingdom 400 mg costs the NHS about £715 as of 2021.[5] This amount in the United States costs about 4,700 USD.[6]

Medical uses

Crohn's Disease: It is used for the treatment of Crohn's disease in people who did not respond sufficiently or adequately to standard therapy.[7][8][9]

Rheumatoid arthritis[1]

Psoriatic arthritis[1]


The initial dose is generally 400 mg followed by 400 mg at 2 and 4 weeks.[1] Doses may than be given every 4 weeks.[1]

Side effects

Significant side effects occur in 2% of people.[10]

Method of action

Three certolizumab molecules (blue) binding a homotrimer of TNF-alpha (tan). Certolizumab can block TNF in both its soluble form (freely circulating in the bloodstream) and its transmembrane form (bound to the membrane of a cell). From PDB: 5WUX​.[11]

Certolizumab pegol is a monoclonal antibody directed against tumor necrosis factor alpha. More precisely, it is a PEGylated Fab' fragment of a humanized TNF inhibitor monoclonal antibody.[12]


Crohn's disease
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.[13][14][12][15][16]
Axial spondyloarthritis
In 2013, a phase 3 double blind randomized placebo-controlled study found significantly positive results in patient self-reported questionnaires, with rapid improvement of function and pain reduction, in patients with axial spondyloarthritis.[17]
Rheumatoid arthritis
Certolizumab appears beneficial in those with rheumatoid arthritis.[10]
