Paller et al. evaluated the long-term efficacy and safety of apremilast in paediatric patients with moderate-to-severe plaque psoriasis through the 52-week Phase III SPROUT trial. The study assessed whether clinical responses were sustained after the placebo-controlled period and whether outcomes differed between treatment sequences.

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.
