Abstract
INTRODUCTION: Low disease activity (LDA)/remission is the target of treatment in patients with psoriatic arthritis (PsA). We assessed the proportions of patients with PsA receiving upadacitinib who achieved LDA/remission over 1 year.
METHODS: This was a post hoc analysis of the double-blind, placebo-controlled SELECT-PsA 1 (also adalimumab-controlled) and SELECT-PsA 2 trials. Treatment targets assessed included LDA/remission defined by Disease Activity in Psoriatic Arthritis (≤ 14/ ≤ 4) and Psoriatic Arthritis Disease Activity Scores (≤ 3.2/ ≤ 1.9), as well as minimal disease activity (MDA)/very low disease activity (VLDA) states (5/7 and 7/7 components, respectively, of MDA criteria). Targets were assessed at 24 and 56 weeks. For binary outcomes, non-responder imputation was used for missing data. Data from patients receiving upadacitinib 30 mg was not included in the analysis.
RESULTS: Overall, 1386 patients were analyzed. Disease control (i.e., LDA/MDA) was achieved at 24 weeks in upadacitinib 15 mg-treated patients across both studies: LDA/MDA was achieved by 25-48% of patients receiving upadacitinib 15 mg versus 2-16% of patients receiving placebo, and remission/VLDA rates were 7-14% with upadacitinib 15 mg versus 0-4% with placebo. The proportions of patients achieving treatment targets were numerically similar to upadacitinib 15 mg and adalimumab. All responses were sustained at 56 weeks.
CONCLUSIONS: Remission and LDA are feasible targets with upadacitinib treatment in patients with PsA.
