Indication for Certolizumab pegol

Population group: only adults (18 years old or older)

Certolizumab pegol, in combination with methotrexate (MTX), is indicated for:

  • the treatment of moderate to severe, active rheumatoid arthritis (RA) in adult patients when the response to disease-modifying antirheumatic drugs (DMARDs) including MTX, has been inadequate. Certolizumab pegol can be given as monotherapy in case of intolerance to MTX or when continued treatment with MTX is inappropriate
  • the treatment of severe, active and progressive RA in adults not previously treated with MTX or other DMARDs.

Certolizumab pegol has been shown to reduce the rate of progression of joint damage as measured by X-ray and to improve physical function, when given in combination with MTX.

For this indication, competent medicine agencies globally authorize below treatments:

Active ingredient

Certolizumab pegol

Certolizumab pegol has a high affinity for human TNFα and binds with a dissociation constant (KD) of 90 pM. TNFα is a key pro-inflammatory cytokine with a central role in inflammatory processes. Certolizumab pegol was shown to neutralise membrane associated and soluble human TNFα in a dose-dependent manner. By inhibiting the action of TNFα, certolizumab pegol reduces inflammation and other symptoms in patients with rheumatoid arthritis.
