Effect of apremilast on hand and whole-body MRI assessments of inflammation in patients with psoriatic arthritis (MOSAIC): a phase 4, multicentre, single-arm, open-label study

Østergaard et al. conducted a phase 4 multicentre, single-arm, open-label study to evaluate the effect of apremilast on MRI-assessed inflammation in PsA patients using PsAMRIS and MRI-WIPE. The study demonstrated that apremilast reduced inflammation in joints and entheses with no structural damage progression. The study also supports the use of MRI as an objective tool in PsA trials.
