Brief Summary:
This is a Phase 2, multicenter, open-label study in subjects with moderate to severe plaque psoriasis aged 6 to 17 years, inclusive, intended to assess the safety, tolerability, and PK of apremilast with 2 weeks of oral apremilast treatment followed by a 48-week extension of apremilast treatment. Moderate to severe plaque psoriasis is defined as Psoriasis Area Severity Index (PASI) ≥ 12, Body Surface Area (BSA) ≥ 10%, and static Physician Global Assessment (sPGA) of ≥ 3. The total study duration for each subject will last for up to a total of 107 weeks which includes screening, treatment (including the PK portion of the study and the extension treatment period), two short-term follow-up periods and a long-term follow-up period.

Detailed Description:

Each subject will undergo a screening period of up to 5 weeks, a treatment period of 2 weeks with PK sample collection, and an extension treatment period of 48 weeks, to allow subjects access to apremilast treatment if medically appropriate (following the completion of the 2 week PK portion). Regardless of when they stop treatment, subjects should complete two post treatment follow-up visits at approximately 4 and 8 weeks after the last dose. All subjects should complete the final follow-up visit at Week 102 or at a timepoint 52 weeks after the last dose of apremilast was taken in subjects who have withdrawn at any time prior to Week 50. At least 32 subjects will be enrolled into this study to provide an adequate PK profile and safety assessment in subjects of different ages and body weight ranges. Subjects will be divided into 2 age groups (adolescents [ages 12 to 17 years, inclusive] and children [ages 6 to 11 years, inclusive]), with at least 16 subjects in each group. Apremilast treatment will start in older and heavier subjects.

Group 1 (ages 12 to 17 years, inclusive; weight ≥ 35 kg)

  • The data collected from the first 8 subjects will be reviewed by an independent data monitoring committee (DMC) to determine if it is appropriate to proceed with dosing the balance of Group 1 subjects and to proceed with dosing in the Group 2 subjects.

and an evaluation of these data by the DMC has been completed.

Group 2 (ages 6 to 11 years, inclusive; weight ≥ 15 kg)

  • The dose regimens (dose strength and/or dose frequency) for these first 8 subjects will be based upon the PK and safety assessments from the first 8 subjects in Group 1.
  • For the remaining subjects in Group 2, the dose (dose strength and/or dose frequency) will be based upon the subject weight as determined by the PK and safety assessments. The dose strength and/or dose frequency will be adjusted for any safety concerns or for unexpected changes in exposure. In the event of a dose regimen adjustment after the second PK and safety assessment, the first 8 subjects in Group 2 will return to the site for the appropriate dosing adjustment.

Arm Intervention/treatment
Experimental: Open label apremilast

Apremilast doses of 10-mg, 20-mg or 30-mg tablets have been selected to determine the dose range in adolescents and children with moderate to severe plaque psoriasis. These pediatric dosages are expected to achieve exposures similar to those achieved in adult psoriasis and psoriatic arthritis (PsA) subjects treated with apremilast 30 mg orally twice daily (BID).

A staggered, stepwise approach by age range and weight (starting with older and heavier subjects) is considered appropriate for this first-time-in-children study. Doses for younger and lower body weight subjects will be adjusted based on safety and PK data from older and heavier subjects.

Subjects will be divided into 2 age groups with at least 16 subjects in each group. Dosing within and between groups will be staggered, based on PK data collected and on a minimum of 2 weeks of safety data.

Drug: Apremilast
Other Name: CC-10004




Primary Outcome Measures :
  1. Number of Participants With Treatment Emergent Adverse Events (TEAEs) [ Time Frame: From first dose of apremilast until 28 days after the last dose; up to 29 July 2019; median treatment duration for adolescents apremilast 20 mg and 30 mg was 50.00 and 50.57 weeks respectively and for children was 50.00 weeks. ]
    A TEAE is an adverse event with a start date on or after the date of the first dose of apremilast and no later than 28 days after the last dose of apremilast. An adverse event is any noxious, unintended, or untoward medical occurrence that may appear or worsen in a subject during the course of a study. It may be a new intercurrent illness, a worsening concomitant illness, an injury, or any concomitant impairment of the subject's health, including laboratory test values, regardless of etiology. A serious AE is any untoward AE that results in death, is life threatening, requires inpatient hospitalization or prolongation of existing hospitalization or in persistent or significant disability/incapacity, results in a congenital anomaly/birth defect or constitutes an important medical event. The investigator assessment of severity/intensity of an event was defined as mild, moderate or severe.

  2. Maximum Observed Plasma Concentration (Cmax) of Apremilast [ Time Frame: For adolescents, a pre-dose sample prior to morning dose and on Day 14 as well as at hours 1, 2, 3, 5, 8 and 12 post dose; for the children, samples were collected 2 hours at predose (prior to morning dose) and at 2, 5 and 12 hours post morning dose. ]
    Maximum observed plasma concentration (Cmax) of apremilast. PK parameters were calculated using non-compartmental methods, plasma concentrations and actual blood sampling times from the intensive sampling schedule.

  3. Time to Maximum Plasma Concentration (Tmax) of Apremilast [ Time Frame: For adolescents, a pre-dose sample prior to morning dose and on Day 14 as well as at hours 1, 2, 3, 5, 8 and 12 post dose; for the children, samples were collected 2 hours at predose (prior to morning dose) and at 2, 5 and 12 hours post morning dose. ]
    Time to maximum observed plasma concentration obtained directly from the observed concentration versus time data. PK parameters were calculated using non-compartmental methods, plasma concentrations and actual blood sampling times from the intensive sampling schedule.

  4. Area Under the Plasma Concentration-time Curve From Time Zero to 12 Hours Post Dose of Apremilast (AUC0-12) [ Time Frame: For adolescents, a pre-dose sample prior to morning dose and on Day 14 as well as at hours 1, 2, 3, 5, 8 and 12 post dose; for the children, samples were collected 2 hours at predose (prior to morning dose) and at 2, 5 and 12 hours post morning dose. ]
    Area under the plasma concentration-time curve from time zero to the 12 hours post dose was calculated using non-compartmental methods, plasma concentrations and actual blood sampling times from the intensive sampling schedule.

  5. Area Under the Plasma Concentration-time Curve From Time Zero to the Last Measurable Concentration of Apremilast (AUC0-t) [ Time Frame: For adolescents, a pre-dose sample prior to morning dose and on Day 14 as well as at hours 1, 2, 3, 5, 8 and 12 post dose; for the children, samples were collected 2 hours at predose (prior to morning dose) and at 2, 5 and 12 hours post morning dose. ]
    Area under the plasma concentration-time curve from time zero to the last quantifiable time point and was calculated using non-compartmental methods, plasma concentrations and actual blood sampling times from the intensive sampling schedule.

  6. Apparent Total Plasma Clearance When Dosed Orally (CL/F) for Apremilast [ Time Frame: For adolescents, a pre-dose sample prior to morning dose and on Day 14 as well as at hours 1, 2, 3, 5, 8 and 12 post dose; for the children, samples were collected 2 hours at predose (prior to morning dose) and at 2, 5 and 12 hours post morning dose. ]
    Apparent total plasma clearance (CL/F) of apremilast was calculated using non-compartmental methods, plasma concentrations and actual blood sampling times from the intensive sampling schedule.

  7. Apparent Total Volume of Distribution When Dosed Orally, Based on Study-State (Vss/F) or in the Terminal Phase (Vz/F) [ Time Frame: For adolescents, a pre-dose sample prior to morning dose and on Day 14 as well as at hours 1, 2, 3, 5, 8 and 12 post dose; for the children, samples were collected 2 hours at predose (prior to morning dose) and at 2, 5 and 12 hours post morning dose. ]
    Apparent total volume of distribution when dosed orally, based on study-state (Vss/F) or in the terminal phase (Vz/F). Pharmacokinetic parameters were calculated using non-compartmental methods, plasma concentrations and actual blood sampling times from the intensive sampling schedule.

  8. Terminal Phase Elimination Half-Life [ Time Frame: For adolescents, a pre-dose sample prior to morning dose and on Day 14 as well as at hours 1, 2, 3, 5, 8 and 12 post dose; for the children, samples were collected 2 hours at predose (prior to morning dose) and at 2, 5 and 12 hours post morning dose. ]
    Terminal-phase elimination half-life (t ½). PK parameters were calculated using non-compartmental methods, plasma concentrations and actual blood sampling times from the intensive sampling schedule.


Secondary Outcome Measures :
  1. Taste and Acceptability of Apremilast Tablets Using the Faces Likert Scale [ Time Frame: Day 1 ]
    Taste and acceptability of the apremilast tablet was assessed using a faces Likert Scale on Day 1, initial dosing. The scale consists of options from 1 (dislike very much, illustrated by a frowning face) to 5 (like very much, illustrated by a smiling face).
