Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Apremilast

Arm Description

After a 5-day titration, participants received 30 mg apremilast tablets orally twice daily (BID) for up to 32 weeks in addition to their existing topical therapy. At week 16 participants were permitted to decrease their use of topical therapy at their own discretion under the direction of their physician.

Outcomes

Primary Outcome Measures

Percentage of Participants Who Achieved an sPGA Score of Clear (0) or Almost Clear (1) at Week 16
The sPGA is an assessment by the Investigator of the overall disease severity at the time of evaluation. Erythema (E), induration (I), and desquamation (D) are scored on a 5-point scale, ranging from 0 (clear) to 4 (severe). The National Psoriasis Foundation Psoriasis Score version of a static PGA is calculated by averaging the total body erythema, induration, and desquamation scores. The overall scores are as follows: 0 = Clear; = Almost Clear; = Mild; = Moderate; = Severe. The percentage of participants with a sPGA response was estimated using a multiple imputation method from 100 imputed data sets.

Secondary Outcome Measures

Percentage of Participants Who Achieved an sPGA Score of Clear (0) or Almost Clear (1) at Week 32
The sPGA is an assessment by the Investigator of the overall disease severity at the time of evaluation. Erythema (E), induration (I), and desquamation (D) are scored on a 5-point scale, ranging from 0 (clear) to 4 (severe). The National Psoriasis Foundation Psoriasis Score version of a static PGA is calculated by averaging the total body erythema, induration, and desquamation scores. The overall scores are as follows: 0 = Clear; = Almost Clear; = Mild; = Moderate; = Severe.
Percentage of Participants Who Achieved a Scalp Physicians Global Assessment (ScPGA) Score of Clear (0) or Almost Clear (1) at Weeks 16 and 32
The ScPGA assesses scalp involvement of psoriasis based on scalp plaque elevation, scaling, and erythema. The 5-point ScPGA scale ranges from 0 (clear), 1 (almost clear), 2 (mild), 3 (moderate), to 4 (severe).
Change From Baseline in Percentage of BSA Affected by Psoriasis at Weeks 16 and 32
The overall body surface area affected by psoriasis was estimated based on the palm area of the participant's hand, which equates to approximately 1% of total body surface area. BSA affected by psoriasis is expressed as a percentage of total body surface area. A negative change from baseline indicates improvement.
Percent Change From Baseline in Pruritus Visual Analog Scale (VAS) at Weeks 2, 16, and 32
Participants were asked to indicate how much itch they have had due to psoriasis in the past week by placing a vertical stroke on a 100 mm line on which the left-hand boundary (0 mm) represented no itch, and the right-hand boundary (100 mm) represented worst itch imaginable. The distance from the mark to the left-hand boundary was recorded. A negative change from baseline indicates improvement.
Mean Change From Baseline in Shiratori's Pruritus Severity Score at Weeks 2, 16, and 32
Shiratori's Pruritus Severity Score is a pruritus (itchiness) severity assessment tool used in Japan. Daytime and nighttime pruritus were evaluated and scored separately. Daytime pruritus was rated on a five-grade scale: 0 (absent), 1 (endurable without scratching; minimal), 2 (subsides with slight scratching; mild), 3 (subsides with considerable scratching; moderate), or 4 (not subsiding with scratching, which prompts repeated scratching; severe). Nighttime pruritus was rated on a five-grade scale: 0 (absent), 1 (slight itching at bedtime but not causing intentional scratching; no difficulty sleeping because of pruritus), 2 (slight itching that subsides with scratching; no difficulty sleeping because of pruritus), 3 (difficulty sleeping because of pruritus that resolves with scratching; unconscious scratching occurs during sleep), or 4 (severe difficulty sleeping due to pruritus; frequent scratching that worsens pruritus). A negative change from baseline indicates improvement.
Percentage of Participants Who Achieved a ≥ 50% Reduction From Baseline in NAPSI Score (NAPSI-50) at Weeks 16 and 32 Among Participants With NAPSI ≥ 1 at Baseline
One target thumb nail or fingernail representing the worst nail psoriasis involvement was selected for assessment at Baseline. The nail matrix was assessed for presence of any of the nail matrix features (pitting, leukonychia red spots in the lunula, crumbling) graded on a scale of 0 (none) to 4 (present in all 4 quadrants). The nail bed was assessed for the presence of any nail bed features (onycholysis, splinter hemorrhages, subungual hyperkeratosis, "oil drop" (salmon patch dyschroma) on a scale from 0 (none) to 4 (present in all quadrants). The sum of the nail matrix and nail bed scores is the total score and ranges from 0 to 8 (worst).
Change From Baseline in Dermatology Life Quality Index (DLQI) at Weeks 16 and 32
The DLQI questionnaire asks participants to evaluate the degree that psoriasis has affected their quality of life in the last week, and includes the following parameters: symptoms and feelings, daily activities, leisure activities, work or school activities, personal relationships and treatment related feelings. Participants answer 10 questions on a scale from 0 (not at all) to 3 (very much), except for Question 7, which first asks whether the participant's skin prevented them from working or studying (Yes (score = 3) or No (score = 0), then If "No", the participant is asked how much their skin was a problem at work or studying over the last week, with responses from 0 (not at all), 1 (a little), or 2 (a lot). The DLQI total score ranges from 0 to 30, with 30 corresponding to the worst quality of life, and 0 corresponding to the best. A negative change from baseline indicates improvement.
Percent Change From Baseline in Psoriasis Area and Severity Index (PASI) Score at Weeks 16 and 32
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. A negative change from baseline indicates improvement.
Percentage of Participants Who Achieved ≥ 75% Reduction From Baseline in PASI Score (PASI-75)
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.
Percentage of Participants Who Achieved ≥ 50% Reduction From Baseline in PASI Score (PASI-50)
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.
Treatment Satisfaction Questionnaire for Medication (TSQM) Sub-domain Scores
The Treatment Satisfaction Questionnaire for Medication (TSQM) version II is a self-administered instrument to understand a participant's satisfaction on current therapy. The TSQM comprises 11 items across 4 domains focusing on effectiveness (Item 1 and 2), side effects (Item 4 to 6), convenience (Item 7 to 9), and global satisfaction (Item 10 and 11). With the exception of Item 3 (experience any side effects; yes or no), all items have five or seven responses. Item scores are summed to give four domain scores, which are in turn transformed to a scale from 0 (extremely dissatisfied) to 100 (extremely satisfied).
Percentage of Participants Who Achieved a Patient Benefit Index (PBI) Score ≥ 1 at Weeks 16 and 32
The Patient Benefit Index (PBI) is used to assess patient-relevant benefits of psoriasis treatment as a function of the most important needs identified by the participant before the start of treatment. Participants were asked to assess the benefits of treatment by completing the Patient Benefit Questionnaire (PBQ), which consists of 25 treatment goal statements scored from 0 (not at all) to 4 (very). The PBI is calculated for each participant by weighing the achievement values of each statement by their importance to the individual patient as assessed prior to the start of treatment. The PBI ranges from 0 (no benefit) to 4 (maximum benefit).
Number of Participants With Treatment-emergent Adverse Events (TEAEs)
The Investigator assessed the severity/intensity of each adverse event as: Mild (asymptomatic or mild symptoms; intervention not indicated; activities of daily life (ADLs) minimally or not affected); Moderate (symptom(s) cause moderate discomfort; local or noninvasive intervention indicated; more than minimal interference with ADLs but able to carry out daily social and functional activities; drug therapy may be required); Severe (symptoms causing severe discomfort/pain; symptoms requiring medical/surgical attention/intervention; interference with ADLs including inability to perform daily social and functional activities; drug therapy required). A serious adverse event is any AE occurring at any dose that: Resulted in death; Was life-threatening; Required inpatient hospitalization or prolongation of existing hospitalization; Resulted in persistent or significant disability/incapacity; Was a congenital anomaly/birth defect; Constituted an important medical event.

12. IPD Sharing Statement

Plan to Share IPD
Yes
IPD Sharing Plan Description
De-identified individual patient data for variables necessary to address the specific research question in an approved data sharing request
IPD Sharing Time Frame
Data sharing requests relating to this study will be considered beginning 18 months after the study has ended and either 1) the product and indication have been granted marketing authorization in both the US and Europe or 2) clinical development for the product and/or indication discontinues and the data will not be submitted to regulatory authorities. There is no end date for eligibility to submit a data sharing request for this study.
IPD Sharing Access Criteria
Qualified researchers may submit a request containing the research objectives, the Amgen product(s) and Amgen study/studies in scope, endpoints/outcomes of interest, statistical analysis plan, data requirements, publication plan, and qualifications of the researcher(s). In general, Amgen does not grant external requests for individual patient data for the purpose of re-evaluating safety and efficacy issues already addressed in the product labelling. Requests are reviewed by a committee of internal advisors. If not approved, a Data Sharing Independent Review Panel will arbitrate and make the final decision. Upon approval, information necessary to address the research question will be provided under the terms of a data sharing agreement. This may include anonymized individual patient data and/or available supporting documents, containing fragments of analysis code where provided in analysis specifications.
