Discovered and developed by AbbVie scientists, upatinib is an oral once-daily, selective and reversible JAK inhibitor. In August 2019, it was approved by the US FDA for the treatment of adults with moderate-to-severe active rheumatoid arthritis who have an insufficient response to or intolerance to methotrexate. The JAK family of proteins mediates the signaling of various inflammatory factors. Upatinib has shown positive results in phase 3 clinical trials for a variety of inflammatory diseases, including rheumatoid arthritis, atopic dermatitis, Crohn's disease, and psoriatic arthritis.
