Brief Summary
This is a Phase 3, multicenter, randomized, placebo-controlled, double-blind study of the efficacy and safety of apremilast (CC-10004) in pediatric subjects with moderate to severe plaque psoriasis.
At least 230 pediatric subjects (ages 6 through 17 years) will be randomized 2:1 to receive either apremilast or placebo for the first 16 weeks and then all subjects will receive apremilast during the 36 week Extension Phase for a total of 52 weeks. Randomization to apremilast arm or placebo arm will be stratified by age group (6 to 11 years or 12 to 17 years). Subjects will receive apremilast treatment of either 20 mg twice daily (BID) or 30 mg BID, depending on weight. This Phase 3 study is being conducted to evaluate the safety and efficacy of apremilast in the treatment of pediatric subjects.

A PHASE 3, MULTI-CENTER, RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED STUDY TO ASSESS THE EFFICACY AND SAFETY OF APREMILAST (CC-10004) IN PEDIATRIC SUBJECTS FROM 6 THROUGH 17 YEARS WITH MODERATE TO SEVERE PLAQUE PSORIASIS
Primary Outcomes
Outcome Description
The sPGA is the assessment by the Investigator of the overall disease severity of plaque psoriasis at the time of evaluation. The sPGA is a 5-point scale ranging from 0 (clear) to 4 (severe), incorporating an assessment of the severity of the three primary signs of the disease: erythema, scaling and plaque elevation. The results presented are for the percentage of participants with a sPGA response. An sPGA response was defined as a score of clear (0) or almost clear (1) with at least a 2-point reduction from baseline at Week 16.
Outcome Measure
Percentage of Participants With a Static Physician Global Assessment (sPGA) Response at Week 16

Secondary Outcomes
Outcome Description
The Psoriasis Area Severity Index (PASI) is a measure of psoriatic disease severity taking into account qualitative lesion characteristics (erythema, thickness, and scaling) and degree of skin surface area involvement on defined anatomical regions. The PASI scores range from 0 to 72, with higher scores reflecting greater disease severity. The results presented are for the percentage of participants with PASI-75. PASI-75 was defined as at least a 75% reduction in PASI score from baseline.

The PASI is a measure of psoriatic disease severity taking into account qualitative lesion characteristics (erythema, thickness, and scaling) and degree of skin surface area involvement on defined anatomical regions. The PASI scores range from 0 to 72, with higher scores reflecting greater disease severity. The results presented are for the percentage of participants with PASI-50. PASI-50 was defined as at least a 50% reduction in PASI score from baseline.

The CDLQI measures how much the participant's psoriasis has affected them over the last week, and includes 10 questions with possible answers ranging from not at all (score of 0) to very much (score of 3). The CDLQI total score ranged from 0 (no effect on the participant's life) to 30 (extremely large effect on the participant's life). The results presented are for the percentage of participants who achieved a total CDLQI score of 0 or 1 at Week 16.
