The FDA has required updates to the boxed warnings in the labeling of the Janus kinase (JAK) inhibitors tofacitinib (Xeljanz, Xeljanz XR), baricitinib (Olumiant), and upadacitinib (Rinvoq) describing increased risks of major adverse cardiovascular events, malignancy, thrombosis, and death with their use. The new warnings were prompted by the results of a postmarketing safety trial with tofacitinib and were added to the labels of baricitinib and upadacitinib based on the presumption of a class effect.

Ulcerative colitis (UC) and Crohn's disease (CD), referred to collectively as inflammatory bowel disease (IBD), are chronic immune-mediated inflammatory conditions. Guidelines for treatment of UC and CD have been updated in recent years

The FDA has approved the oral Janus kinase (JAK) inhibitor upadacitinib (Rinvoq – Abbvie) for treatment of moderately to severely active ulcerative colitis in adults who have had an inadequate response to or cannot tolerate one or more tumor necrosis factor (TNF) inhibitors. Upadacitinib is the second JAK inhibitor to be approved for this indication; tofacitinib (Xeljanz) was the first. Upadacitinib is also approved for treatment of rheumatoid arthritis, psoriatic arthritis, atopic dermatitis, and ankylosing spondylitis.
