Upadacitinib (Rinvoq) has been approved by the Food and Drug Administration for treatment of adults with moderately to severely active RA, according to a release from its developer. The indication specifies that patients must have shown inadequate response or intolerance to methotrexate.
The approval is based on the SELECT program, which included 4,400 patients across five studies that tested the oral Janus kinase inhibitor in various settings, such as alone or with methotrexate. All primary and secondary endpoints were met in these trials. For example, among patients with inadequate response to methotrexate in one study, 68% of those treated with 15-mg upadacitinib monotherapy achieved 20% improvement in American College of Rheumatology response criteria (ACR20) at week 14 versus 41% of those who had continued on methotrexate. In another study of patients with in adequate response to methotrexate, 71% of those treated with upadacitinib/methotrexate combination therapy achieved ACR20 at week 12 versus 36% of those receiving placebo and methotrexate. Compared with other treatments, better rates of clinical remission and radiographic inhibition were seen with upadacitinib-based therapies, too.
Upadacitinib carries a boxed warning – the most serious warning the FDA issues – for risks of serious infection, malignancy, and thrombosis; these serious risks should be weighed against treatment benefits in any patients with increased risk for these problems or currently experiencing any of them. Concomitant use with other JAK inhibitors, biologic DMARDs, or with potent immunosuppressants is not recommended; its use also is not recommended for patients with severe hepatic impairment. The most common adverse reactions are upper respiratory tract infection, nausea, cough, and pyrexia. Live vaccines should be avoided with patients taking this drug, and patients who are breastfeeding should be advised against use of it.
More prescribing information can be found in the drug’s label, which can be found on the FDA’s website.
Upadacitinib is also being evaluated for treatment of other immune-mediated diseases.
