This study will evaluate the clinical efficacy, the patients quality of life, and safety of oral apremilast 30 mg twice daily (BID) compared to placebo, in adult patients with moderate plaque psoriasis during the 16 week Placebo controlled Phase and then upto 1 year in the Extension Phase of the trial.
This is a Phase 4, multicenter, randomized, placebo-controlled, double-blind study of the efficacy and safety of apremilast in subjects with moderate plaque psoriasis. 221 participants were randomized 2 (apremilast):1 (placebo) at approximately 25 sites in the United States. Those randomized to the apremilast treatment group received apremilast 30 mg tablets orally twice daily for 52 weeks. Those randomized to the placebo treatment group received placebo tablets (identical in appearance to the apremilast 30 mg tablets) orally twice daily (BID) for 16 weeks. Beginning Week 16, those initially randomized to placebo were switched to receive apremilast 30 mg BID for an additional 36 weeks (52 weeks total).
Study enrolled adult patients with stable moderate plaque psoriasis, who are naïve to systemic psoriasis treatments.

| Mean Percentage Change From Baseline in the Product of BSA (%) and the sPGA Which is Considered as the Total Psoriasis Severity Index at Week 16 | BSA is a measurement of involved skin. The overall BSA affected by psoriasis is estimated based on the palm area of the participant's hand (entire palmar surface or "handprint" including the fingers), which equates to approximately 1% of total body surface area. The sPGA is a 6-point scale ranging from 0 (clear), 1 (almost clear), 2 (mild), 3 (moderate), to 4 (severe), 5 (very severe) incorporating a separate assessment of the severity of the three primary signs of the plaques of all involved areas: erythema, scaling and plaque elevation with an overall sPGA calculated as (E + I + D)/3. Scores for each assessment are rounded to the nearest whole number to result in the final score. The range of BSA*sPGA mean percentage change from baseline to week 16 (end of phase) were -100 to 344.4 and -100 to 100 for the placebo and apremilast groups respectively.

| Mean Change From Baseline in the Dermatology Life Quality Index (DLQI) Total Score at Week 16 | DLQI is a simple, compact, and practical questionnaire for use in a dermatology clinical setting to assess limitations related to the impact of skin disease. The instrument contains ten items dealing with the participant's skin. With the exception of Item Number 7, the participant responds on a four-point scale, ranging from "Very Much" (score 3) to "Not at All" or "Not relevant" (score 0). Item Number 7 is a multi-part item, the first part of which ascertains whether the participant's skin prevented them from working or studying (Yes or No, scores 3 or 0 respectively), and if "No," then the participant is asked how much of a problem the skin has been at work or study over the past week, with response alternatives being "A lot," "A little," or "Not at all" (scores 2, 1, or 0 respectively). The DLQI total score is derived by summing all item scores, which has a possible range of 0 to 30, with 30 corresponding to the worst quality of life, and 0 corresponding to the best. |

| Secondary | Mean Percentage Change From Baseline in the Product of BSA (%) x sPGA at Week 52 | BSA is a measurement of involved skin. The overall BSA affected by psoriasis is estimated based on the palm area of the participant's hand (entire palmar surface or "handprint" including the fingers), which equates to approximately 1% of total body surface area. The sPGA is a 6-point scale ranging from 0 (clear), 1 (almost clear), 2 (mild), 3 (moderate), to 4 (severe), 5 (very severe) incorporating a separate assessment of the severity of the three primary signs of the plaques of all involved areas: erythema, scaling and plaque elevation with an overall sPGA calculated as (E + I + D)/3. Scores for each assessment are rounded to the nearest whole number to result in the final score. | Apremilast participants who entered and were treated in the apremilast extension phase. | Posted | Mean | Standard Deviation | percentage change | Baseline to Week 52 |
