The TICOPA trial is designed as a randomised, controlled, parallel group, open label, multi-centre clinical trial of 206 patients with recent onset psoriatic arthritis. Patients will be randomised on a 1:1 basis to receive either standard care (12 weekly review) or tight control (4 weekly review) for a period of 48 weeks. The hypothesis is that tight control of inflammation will lead to a better outcome in terms of joint inflammation, joint damage, pain and quality of life for people with PsA. This imaging undertaken within the study will provide a further measure of joint inflammation and damage and will improve understanding of the relationships between inflammation, damage and bony proliferation in psoriatic arthritis.
