Tumor Necrosis Factors (TNF)-α Blockade for Psoriatic Arthritis

• Status: Completed
• Trial end date: 2009-03-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is:

• To elucidate the immunomodulating properties of anti-TNF-α therapy in patients with psoriatic arthritis (PsA).

• To ascertain whether magnetic resonance imaging (MRI) is a sensitive tool in measuring early response after therapy with anti-TNF-α in the PsA wrist using the Outcome Measures in Rheumatoid Arthritis Clinical Trials (OMERACT) guidelines for rheumatoid arthritis (RA).

• To assess whether the lipid and other cardiovascular risk profiles would improve after anti-TNF-α therapy in patients with PsA.

• Phase: Phase 4
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Chinese University of Hong Kong
• Treatments: Etanercept; Infliximab
