↵* Data as observed. Based on patients randomized to apremilast: placebo/apremilast 20 mg BID and placebo/apremilast 30 mg BID groups include patients who were randomized to placebo at baseline and re-randomized to apremilast 20 mg BID and apremilast 30 mg BID, respectively, at Weeks 16 or 24; apremilast 20 mg BID and apremilast 30 mg BID groups include patients randomized to the respective regimen at baseline.
↵§ Increase indicates improvement.
