Efficacy and Safety Study of Apremilast (CC-10004) in Pediatric Subjects From 6 Through 17 Years of Age With Moderate to Severe Plaque Psoriasis
- Registration Number
- NCT03701763
- Lead Sponsor
- Amgen
- 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
Name Time Method Percentage of Participants With a Static Physician Global Assessment (sPGA) Response at Week 16 Baseline 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
Name Time Method Percentage Change From Baseline in Body Surface Area (BSA) Affected by Psoriasis at Week 16 Baseline 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 16 Baseline 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 Period 52 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 Period 52 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 16 Baseline 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 16 Baseline 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 16 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). 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 16 Baseline 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 With Diarrhea During the Apremilast Exposure Period Day 1 up to approximately 365 days Diarrhea was defined as having 3 or more liquid or watery stools in a day. Participants and their parent/guardian were supplied with diaries (either paper or electronic) that were filled out daily to record and describe any diarrhea and associated symptoms.
Number of Participants Who Experienced a Treatment-emergent Adverse Event (TEAE) During the Placebo-controlled Phase 16 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.

Number of Female Participants at Stage I-V of Sexual Development Per Tanner Staging of Sexual Development Week 52 The Tanner Staging of sexual development is a scale of physical development as children transition into adolescence and then adulthood. The scale defines physical measurements of development based on characteristics, such as the size of the breasts, genitals, testicular volume, and growth of pubic hair. The scale ranges from stage I (pre-adolescent) to stage V (adult development). The results presented are for the number of participants at stage I-V of development.
