Upadacitinib for psoriatic arthritis refractory to biologics : SELECT-PsA 2

Background: Upadacitinib is a Janus kinase inhibitor under evaluation for the treatment of psoriatic arthritis (PsA). We evaluated upadacitinib in patients with PsA and prior inadequate response or intolerance to at least one biologic disease-modifying antirheumatic drug (DMARD). Methods: In this 24-week randomised, placebo-controlled, double-blind, phase 3 trial, 642 patients were randomised (2:2:1:1) to once per day upadacitinib 15 mg or 30 mg, placebo followed by upadacitinib 15 mg or placebo followed by upadacitinib 30 mg at week 24. The primary endpoint was the proportion of patients achieving American College of Rheumatology (ACR) 20 response at week 12. Achievement of minimal disease activity (MDA) was assessed at week 24. Treatment-emergent adverse events are reported for all patients who received at least one dose of trial drug. Results: At week 12, significantly more patients receiving upadacitinib 15 mg and 30 mg versus placebo achieved ACR20 (56.9% and 63.8% vs 24.1%; p<0.001 for both comparisons). At week 24, MDA was achieved by more upadacitinib 15 mg-treated (25.1%) and 30 mg-treated patients (28.9%) versus placebo (2.8%; p<0.001 for both comparisons). Generally, the rates of treatment-emergent adverse events were similar with placebo and upadacitinib 15 mg and higher with upadacitinib 30 mg at week 24. Rates of serious infections were 0.5%, 0.5% and 2.8% with placebo, upadacitinib 15 mg and upadacitinib 30 mg, respectively. Conclusion: In this trial of patients with active PsA who had inadequate response or intolerance to at least one biologic DMARD, upadacitinib 15 mg and 30 mg was more effective than placebo over 24 weeks in improving signs and symptoms of PsA

Upadacitinib in Patients with Psoriatic Arthritis and Inadequate Response to Biologics: 56-Week Data from the Randomized Controlled Phase 3 SELECT-PsA 2 Study.

INTRODUCTION: Upadacitinib is a Janus kinase inhibitor under investigation in patients with psoriatic arthritis (PsA). This study assessed the 56-week efficacy and safety of upadacitinib in patients with PsA and an inadequate response or intolerance to biologic therapy. METHODS: In the phase 3 SELECT-PsA 2 study, patients were randomized to 56 weeks of blinded treatment with oral upadacitinib 15 or 30 mg once daily, or placebo switched to upadacitinib 15 or 30 mg once daily at week 24. Efficacy endpoints included the proportion of patients achieving 20/50/70% improvement in American College of Rheumatology criteria (ACR20/50/70), 75/90/100% improvement in Psoriasis Area and Severity Index (PASI75/90/100), and minimal disease activity. Safety was assessed throughout the study. RESULTS: Of 641 patients who received ≥ 1 dose of study drug, 479 (74.7%) completed 56 weeks of treatment. Improvements in the proportion of patients achieving ACR20/50/70, PASI75/90/100, and minimal disease activity were maintained with both doses of upadacitinib through 56 weeks. Week 56 results for patients who switched from placebo to upadacitinib at week 24 were similar to those for patients originally randomized to the upadacitinib groups. The exposure-adjusted event rate for serious infections was 2.6 and 6.1 events/100 patient-years in the upadacitinib 15 and 30 mg groups, respectively. Herpes zoster occurred more frequently with upadacitinib 30 versus 15 mg; most cases were non-serious. CONCLUSION: In patients with PsA who had an inadequate response or intolerance to biologic therapy, the efficacy of upadacitinib was maintained over 56 weeks with no new significant safety signals observed.
