Response to Tofacitinib in Patients with Psoriatic Arthritis and Probable Anxiety/Depressive Disorder: A Post Hoc Analysis of Phase 3 Trials
摘要
Mental health status potentially influences treatment responses. The effect of probable anxiety and/or depressive disorder (pADD) on tofacitinib efficacy, patient-reported outcomes (PROs), and safety in psoriatic arthritis (PsA) was assessed.
MethodsThis was a post hoc analysis of two phase 3 trials in patients with PsA receiving tofacitinib, adalimumab, or placebo, and an open-label extension study. Outcomes were stratified by presence/absence of baseline pADD (Short Form-36 Health Survey [SF-36] Mental Component Summary score ≤ 38/ > 38). American College of Rheumatology ≥ 20%, ≥ 50%, and ≥ 70% (ACR20/50/70) responses, remission and/or low disease activity based on Psoriatic Arthritis Disease Activity Score and Disease Activity Index for Psoriatic Arthritis score, minimal disease activity, and PROs (pain/Health Assessment Questionnaire-Disability Index/fatigue) were assessed through month 36. Safety was assessed through month 12.
ResultsOverall, 323/706 (45.8%) patients had baseline pADD; of these, a higher proportion were female versus male (61.9% vs. 38.1%). Numerically higher proportions achieved efficacy/PRO responses with tofacitinib versus placebo, regardless of baseline pADD (month 3). Responses with tofacitinib were generally similar in patients with versus without baseline pADD (e.g., month 3 ACR20 responses: 54.0% vs. 58.5%); some differences were observed at later time points (e.g., month 9 minimal disease activity: 25.0% vs. 43.8%; p < 0.05). Baseline pADD did not appear to affect the incidence of treatment-emergent adverse events.
ConclusionsBaseline pADD was frequent in patients with PsA initiating tofacitinib and was higher in female patients. Tofacitinib-treated patients had generally similar efficacy/safety outcomes, regardless of baseline pADD. Some differences in efficacy outcomes were noted in the longer term (9–12 months). Limitations of this study include small numbers in some analyses and use of SF-36 as pADD proxy.
