Psoriatic Arthritis

Psoriatic arthritis is a type of arthritis that often occurs with psoriasis of the skin. Psoriasis is a common, chronic skin condition that causes red patches on the body. About 1 in 20 people with psoriasis will develop arthritis with the skin condition. In most cases, psoriasis comes before the arthritis.

Research + Clinical Trials


A Phase 3, Randomized, Double-Blind, Study Comparing Upadacitinib (ABT-494) to Placebo and to Adalimumab in Subjects with Active Psoriatic Arthritis Who Have a History of Inadequate Response to at Least One Non-Biologic Disease Modifying Anti-Rheumatic Drug (DMARD) – SELECT – PsA 1

This study evaluates the safety and efficacy of the study drug ABT-494 as compared to a current FDA-approved drug, adalimumab, as well as a placebo. ABT-494 aims to inhibit the JAK1, which is partially responsible for inflammation associated with psoriatic arthritis. Although ABT-494 is not FDA approved, it has seen success in the first 2 phases of trials.
