Golimumab; Uses, Dosage, Side Effects, Interactions

Golimumab is a human monoclonal antibody which is used as an immunosuppressive drug. Golimumab targets tumor necrosis factor alpha (TNF-alpha), a pro-inflammatory molecule and hence is a TNF inhibitor. Profound reduction in C-reactive protein (CRP) levels, interleukin (IL)-6, intercellular adhesion molecules (ICAM)-1, matrix metalloproteinase (MMP)-3, and vascular endothelial growth factor(VEGF) demonstrates golimumab as an effective modulator of inflammatory markers and bone metabolism.

Golimumab is a human IgG1қ monoclonal antibody derived from immunizing genetically engineered mice with human TNFα. Golimumab binds and inhibits soluble and transmembrane human TNFα. Increased TNFα is associated with chronic inflammation. Thus golimumab is indicated for use in adults (i) as an adjunct to methotrexate treatment in patients with moderate to severe active rheumatoid arthritis (RA), (ii) alone or as an adjunct to methotrexate treatment in patients with active psoriatic arthritis (PsA), (iii) as a single agent in patients with active ankylosing spondylitis (AS), and (iv) as a single agent in patients with moderate to severe ulcerative colitis (UC) who require chronic steroids or have experienced intolerance or only a partial response to previous medications.

Mechanism of Action of Golimumab

As a human monoclonal antibody, golimumab binds and inhibits soluble and transmembrane human TNFα. Inhibition of TNFα prevents it binding to its receptors, which prevents both leukocyte infiltration through prevention of cell adhesion proteins such as E-selectin, ICAM-1 and VCAM-1, and pro-inflammatory cytokine secretion such as IL-6, IL-8, G-CSF, and GM-CSF in vitro. Consequently, in patients with chronic inflammatory conditions, decreases in ICAM-1 and IL-6 as well as C-reactive protein (CRP), matrix metalloproteinase 3 (MMP-3), and vascular endothelial growth factor (VEGF) were observed.
