Upadacitinib efficacy proves to be greater than placebo, and non-inferior to adalimumab, in treating patients with psoriatic arthritis (PsA). Already approved for the treatment of rheumatoid arthritis, McInnes, et al. studied oral upadacitinib at a dose of 15 mg or 30 mg, alongside placebo or adalimumab, in this 24-week, Phase III trial, in over 1700 patients with PsA. At the primary endpoint (Week 12), ACR20 response was greater with upadacitinib than placebo, and non-inferior to adalimumab; ...

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. Despite the availability of bDMARDs in PsA, only a small proportion of patients achieve the recommended target of minimal disease activity; as such, additional treatment options are needed. Upadacitinib is under evaluation for PsA. This paper reports the 24-week data...

Arthritis Rheumatol DOI 10.1002/art.40054. Accepted article.

In this Phase 2b study in patients with moderate to severe RA, once-daily peficitinib in combination with limited csDMARDs reduced the symptoms of RA, demonstrated a dose-dependent ACR20 response rate over 12 weeks, and showed acceptable tolerability. This 12-week study included patients who had an inadequate response or intolerance to csDMARDs (N=289). Patients were randomised 1:1:1:1:1 to peficitinib 25-, 50-, 100, 150 mg or matching placebo. Statistically significant differences in the AC...

This Phase 2b study of peficitinib (ASP015K), an orally administered once-daily JAK inhibitor, plus MTX, demonstrated efficacy across multiple secondary endpoints with higher peficitinib doses. Peficitinib in combination with MTX was well tolerated with a safety profile that was consistent with previous studies. A high placebo response rate was seen in both Latin and North America, when patient data were stratified. This high placebo rate is problematic for the accurate interpretation of pefic...
