Tofacitinib is an oral, Janus kinase (JAK) molecule, which selectively inhibits Janus-associated tyrosine kinases JAK1 and JAK3. It has already shown efficacy in the treatment of rheumatoid arthritis and the prevention of organ allograft rejection in kidney transplantation. Two separate phase III placebo-controlled trials, assessing 8-week efficacy of tofacitinib induction for ulcerative colitis (UC), demonstrated superiority when compared with placebo. Tofacitinib also demonstrated robust efficacy versus placebo in the 52-week maintenance component of the same study. Tofacitinib has been recommended by the National Institute for Health and Care Excellence as an effective treatment option for adult patients with moderate to severe UC when conventional therapy or a biological agent cannot be tolerated or the disease has responded inadequately or lost response to treatment. We review the guidelines and provide brief commentary on the post hoc analysis related to lipid increases and thromboembolism risk, which have lead to changes in current therapeutic guidance.
