Spondyloarthritis & psoriatic arthritis

Upadacitinib in active non-radiographic axial spondyloarthritis: 2-year data from the phase 3 SELECT-AXIS 2 study

Arthritis Res TherPublished Randomised controlled trial with open-label extension

Authors' conclusion

Treatment with upadacitinib demonstrated consistent improvement and maintenance of treatment effect across efficacy endpoints through 2 years; no new safety signals were identified with additional exposure.
