Anti-tumour necrosis factor alphas (anti-TNFs) such as infliximab (e.g., Remicade©) are biologics that are proven effective against autoimmune inflammatory diseases. Biologics are large, protein-based agents used to block inflammation for a variety of serious diseases. Infliximab can be used for a variety of chronic inflammatory conditions including rheumatoid arthritis (RA), ankylosing spondylitis (AS), inflammatory bowel disease (IBD) including ulcerative colitis (UC) and Crohn’s disease (CD), psoriatic arthritis (PA), and plaque psoriasis (PP).
