EU CTIS ID: 2023-507415-35-00

What this study is testing

To evaluate the efficacy of tildrakizumab compared to placebo in anti-TNF experienced subjects with active psoriatic arthritis (PsA) as measured by the proportion of subjects achieving a 20% reduction from Baseline in American College of Rheumatology response criteria [ACR20] at week 24. To assess the safety and tolerability of tildrakizumab in subjects with active PsA at Week 24.

Subjects may not be receiving both leflunomide and MTX concomitantly.
  • For subjects receiving oral corticosteroids: the subject must be on a stable dose (not to exceed the equivalent of 10 mg of prednisone per day) for ≥ 4 weeks prior to initiation of IMP, and be expected to maintain a stable dose for the first 24 weeks of the study.
  • Subject has a negative evaluation for tuberculosis (TB) within 4 weeks before initiating IMP, defined as a negative QuantiFERON test.
