How does certolizumab pegol work?
Certolizumab pegol is a type of biologic medicine called an anti-tumor necrosis factor (anti-TNF). This type of drug blocks proteins called tumor necrosis factor alpha (TNF-alpha). TNF-alpha proteins trigger inflammation in the body. People with IBD, including Crohn’s disease, may have too much inflammation in their digestive tract. This inflammation causes their symptoms.1-3
By targeting TNF-alpha and affecting the way it causes inflammation, certolizumab pegol can help to reduce inflammation. For many people with moderate or severe Crohn’s disease, certolizumab pegol can help reduce symptoms and lengthen periods of remission.1,2
