This clinical trial is focused on studying the effects of a medication called Upadacitinib on individuals with Psoriatic Arthritis. Psoriatic Arthritis is a type of arthritis that affects some people who have psoriasis, a condition that features red patches of skin topped with silvery scales. The medication being tested, Upadacitinib, is taken in the form of prolonged-release tablets, which means the medicine is released slowly into the body over time.
The purpose of this study is to understand how Upadacitinib affects pain processing in the brain of people with Psoriatic Arthritis. This is done by observing changes in brain activity using a method called fMRI, which stands for functional magnetic resonance imaging. This imaging technique helps researchers see how different parts of the brain respond to the medication over time.
Participants in the study will take Upadacitinib and have their brain activity monitored at different points during the study. The study will last for several weeks, and participants will have regular check-ups to monitor their progress and any changes in their condition. The goal is to gather information on how the medication affects pain and brain activity in the short and long term.
