Upadacitinib tartrateProduct ingredient for Upadacitinib

Upadacitinib is an oral Janus kinase (JAK)1-selective inhibitor and a disease-modifying antirheumatic drug (DMARD) used in the treatment of rheumatoid arthritis to slow down disease progression. Rheumatoid arthritis is a chronic autoimmune inflammatory disease affecting the peripheral joints. It is characterized by synovial inflammation and hyperplasia, autoantibody production, cartilage damage and bone destruction, leading to co-morbidities.⁴ Despite a variety of therapeutic agents available for treatment, up to 40% of the patients do not respond to current therapies, including biological therapies.⁶ The etiology of the disease is mostly unknown; however, the role of JAK as a driver of immune-mediated conditions was discovered, leading to the use of JAK as therapeutic targets for rheumatoid arthritis.⁵ To reduce dose-related toxicity (as seen with some pan-JAK inhibitors) without significantly affecting efficacy, more selective JAK1 inhibitors, upadacitinib and filgotinib, were developed.⁴

The FDA approved upadacitinib in August 2019 and it is used for the treatment of active rheumatoid arthritis, psoriatic arthritis, atopic dermatitis, ulcerative colitis, and ankylosing spondylitis.⁹ In December 2019, it was additionally approved by the European Commission and Health Canada.^10,15 Upadacitinib is marketed under the brand name RINVOQ for oral administration.⁹
