Certolizumab pegol is a tumor necrosis factor (TNF) blocker used to treat a variety of autoimmune and autoinflammatory conditions like Crohn's disease, rheumatoid arthritis, active psoriatic arthritis, ankylosing spondylitis, axial spondyloarthritis, and plaque psoriasis.
Certolizumab pegol is a tumor necrosis factor (TNF) blocker used to treat a variety of autoimmune and autoinflammatory conditions like Crohn's disease, rheumatoid arthritis, active psoriatic arthritis, ankylosing spondylitis, axial spondyloarthritis, and plaque psoriasis.
Certolizumab targets the activation of TNF-alpha with high affinity (KD 90 pM and IC90 0.004 mcg/ml) which inhibits the downstream inflammatory process. It acts by binding and neutralizing the soluble and membrane portions of TNF-alpha without inducing complement or antibody-dependent cytotoxicity due to the lack of the Fc region. The inhibition of TNF-alpha is achieved in a dose-dependent manner and it does not present activity against lymphotoxin alpha (TNF-beta). One additional feature od certolizumab pegol is that, due to the presence of the PEGylation, it is more significantly distributed into inflamed tissues when compared to other TNF-alpha inhibitors such as infliximab and adalimumab.
Certolizumab pegol has been approved for several different conditions listed below: In Canada, certolizumab pegol is additionally approved in combination with methotrexate for the symptomatic treatment, including major clinical response, and for the reduction of joint damage in adult patients with moderately to severely active rheumatoid arthritis and psoriatic arthritis. Inflammation is a biological response against a potential threat. This response can be normal but in certain conditions, the immune system can attack the body's normal cells or tissues which causes an abnormal inflammation. TNF-alpha has been identified as a key regulator of the inflammatory response. The signaling cascades of this inflammatory mediator can produce a wide range of reactions including cell death, survival, differentiation, proliferation and migration.
