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.

Detailed Description

Treatment will be assigned by weight with subjects 20 kg to \< 50 kg receiving apremilast 20 mg BID or placebo BID and subjects ≥ 50 kg receiving apremilast 30 mg BID or placebo BID. Total study duration is up to 71 weeks. Subjects completing all 52 weeks of the treatment and extension phase will be able to enter the Long-term study. Subjects not entering the Long-term study will return for 3 observational follow-up visits, 4, 8 and 14 weeks after last dose of study drug.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With a Static Physician Global Assessment (sPGA) Response at Week 16Baseline to Week 16

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.

Secondary Outcome Measures
NameTimeMethod
Percentage Change From Baseline in Body Surface Area (BSA) Affected by Psoriasis at Week 16Baseline and Week 16

BSA is a measurement of involved skin of the whole body affected by psoriasis, which ranges from 0% to 100%. Positive percentage change from baseline indicates that a greater BSA was affected by psoriasis. A negative percentage change from baseline indicates that a lesser BSA was affected by psoriasis.

Percentage Change From Baseline in Total PASI Score at Week 16Baseline and Week 16

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. Positive percentage change from baseline scores indicate a worsening of disease severity, and negative percentage change from baseline scores indicate an improvement in disease severity.

Number of Participants Who Experienced a TEAE During the Apremilast Exposure Period52 weeks

An AE was defined as any noxious, unintended, or untoward medical occurrence that may appear or worsen in a participant during the course of the study. A TEAE is any AE that occurred after first dose of the investigational product.

Number of Participants Who Experienced a TRAE During the Apremilast Exposure Period52 weeks

A TREAE is any AE that is determined by the Investigator to have a possibly causal relationship to the investigational product.

Percentage of Participants Who Achieved At Least 75% Reduction in Psoriasis Area Severity Index (PASI-75) From Baseline at Week 16Baseline and Week 16

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.

Percentage of Participants Who Achieved At Least 50% Reduction in Psoriasis Area Severity Index (PASI-50) From Baseline at Week 16Baseline and Week 16

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.

Percentage of Participants Who Achieved a Children's Dermatology Life Quality Index (CDLQI) Score of 0 or 1 at Week 16Week 16

The CDLQI is designed to measure the impact of skin disease on children's quality of life. 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.

Change From Baseline in CDLQI Score at Week 16Baseline and Week 16

The CDLQI is designed to measure the impact of skin disease on children's quality of life. 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). A positive change from baseline score indicates that a participant's quality of life has worsened. A negative change from baseline score indicates that a participant's quality of life has improved.

Number of Participants Who Experienced a Treatment-emergent Adverse Event (TEAE) During the Placebo-controlled Phase16 weeks

An adverse event (AE) was defined as any noxious, unintended, or untoward medical occurrence that may appear or worsen in a participant during the course of the study. A TEAE is any AE that occurred after first dose of the investigational product.
