NORTH CHICAGO, Ill., Nov. 9, 2021 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced results from new post-hoc analyses from the Phase 3 SELECT-PsA 1 and SELECT-PsA 2 trials assessing the efficacy of upadacitinib (RINVOQ®) on axial symptoms in adult patients with active psoriatic arthritis (PsA) and axial involvement. The analysis showed that patients with active PsA demonstrated numerically greater clinical responses related to their axial involvement with upadacitinib (15 mg, once daily) compared to placebo at week 24 across both studies and consistently numerically higher responses compared to HUMIRA® (adalimumab) at week 24 in SELECT-PsA 1.1
Axial involvement was defined by investigator assessment and patient-reported-outcome-based criteria (Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) ≥4 and BASDAI Question 2 ≥4 at baseline).1 These results will be featured at the American College of Rheumatology (ACR) Convergence 2021, in an oral presentation on Tuesday, Nov. 9, from 3:30-3:45 p.m. CT (Abstract #1945).
"These data further add to the body of evidence that support the potential of upadacitinib to be an important treatment option that helps reduce the impact of the many disease manifestations of psoriatic arthritis," said Thomas Hudson, M.D., senior vice president, research and development, chief scientific officer, AbbVie. "We remain committed to advancing research across our portfolio of therapies to help improve care for more people living with rheumatic diseases, including psoriatic arthritis."
At week 24, upadacitinib showed numerically greater responses than adalimumab across all BASDAI and Ankylosing Spondylitis Disease Activity Score (ASDAS) endpoints in SELECT-PsA 1.1 The proportion of patients achieving ASDAS clinically important improvement (CII) at week 24 was greater with upadacitinib (69.8%) versus adalimumab (54.1%, nominal P
