Psoriatic Arthritis Clinical Trial

Official title: Efficacy of Tofacitinib in Reduction of Inflammation Detected on MRI in Patients With Psoriatic ArthritiS PresenTing With Axial InvOlvement - a Randomized, Double-Blind, Placebo-Controlled, Multicenter Trial

Status Recruiting

Clinical Trial Summary

To evaluate the efficacy of Tofacitinib in reducing inflammation in the sacroiliac joints and spine on magnetic resonance imaging (MRI) in patients with active Psoriatic Arthritis (PsA) with axial Involvement (BASDAI [Bath Ankylosing Spondylitis Disease Activity Index] ≥ 4 and total backpain ≥ 4 despite treatment with NSAIDs plus evidence of active inflammation in the sacroiliac joints or spine on MRI).

Clinical Trial Description

This study is a prospective, randomized, double-blind, placebo-controlled, multicenter study to investigate the efficacy of Tofacitinib in reducing inflammation in the sacroiliac joints and in the spine on MRI in patients with active axial PsA.

Eligible patients (n=80) will be randomized 1:1 to receive either Tofacitinib 5mg orally twice daily or placebo for a 12-week period. After week 12, all patients will receive Tofacitinib 5mg orally twice daily for another 12 weeks. The study duration will include a 6-week screening period, a 24-week treatment period and a safety follow-up period of 4 weeks. Patients will be closely monitored throughout the study on a total of 11 visits. Safety data will be collected in the form of adverse events, vital parameters, physical examinations, and laboratory parameters throughout the study.

The baseline MRI of the whole spine and sacroiliac (SI) joints will be performed within the 6-week screening period to confirm the presence of active inflammation (bone marrow edema) compatible with Spondyloarthritis (will be assessed by a central reader), at week 12 to evaluate the primary study endpoint, and at week 24 to evaluate the secondary endpoint.

The primary study endpoint will be an improvement of the total Berlin MRI score for sacroiliac joints and spine at week 12 as compared to baseline. ;
