Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Subjects Achieving a Minimum 75% Improvement From Baseline in the Psoriasis Area and Severity Index (PASI-75) at End-of-treatment (EOT)
Time Frame: End of Treatment (Up to 16 Weeks)
|
The psoriasis area and severity index (PASI) combines the assessment of the severity of lesions (scaling, redness and plaque thickness) and the area affected into a single score in the range of 0.0 (no disease) to 72.0 (maximal disease). The body is divided into four sections: (1) Head and neck; (2) Upper limbs; (3) Trunk (including axillae and groin); and (4) Lower limbs (including buttocks). The PASI score can vary in increments of 0.1 and range from 0.0 to 72.0, with higher scores representing greater severity of psoriasis. The PASI-75 response rate is defined as at least 75 percent (%) reduction in PASI score at EOT (up to 16 weeks) relative to Baseline. |
End of Treatment (Up to 16 Weeks)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Subjects Achieving a Minimum 50% Improvement From Baseline in the Psoriasis Area and Severity Index (PASI-50) at EOT
Time Frame: End of Treatment (Up to 16 Weeks)
|
The PASI combines the assessment of the severity of lesions (scaling, redness and plaque thickness) and the area affected into a single score in the range of 0.0 (no disease) to 72.0 (maximal disease). The body is divided into four sections: (1) Head and neck; (2) Upper limbs; (3) Trunk (including axillae and groin); and (4) Lower limbs (including buttocks). The PASI score can vary in increments of 0.1 and range from 0.0 to 72.0, with higher scores representing greater severity of psoriasis. The PASI-50 response rate is defined as at least 50 percent (%) reduction in PASI score at EOT (up to 16 weeks) relative to Baseline. |
End of Treatment (Up to 16 Weeks)
|
Percentage of Subjects Achieving a Minimum 90% Improvement From Baseline in the Psoriasis Area and Severity Index (PASI-90) at EOT
Time Frame: End of Treatment (Up to 16 Weeks)
|
The PASI combines the assessment of the severity of lesions (scaling, redness and plaque thickness) and the area affected into a single score in the range of 0.0 (no disease) to 72.0 (maximal disease). The body is divided into four sections: (1) Head and neck; (2) Upper limbs; (3) Trunk (including axillae and groin); and (4) Lower limbs (including buttocks). The PASI score can vary in increments of 0.1 and range from 0.0 to 72.0, with higher scores representing greater severity of psoriasis. The PASI-90 response rate is defined as at least 90 percent (%) reduction in PASI score at EOT (up to 16 weeks) relative to Baseline. |
End of Treatment (Up to 16 Weeks)
|
Percent Change From Baseline in Psoriasis Area and Severity Index (PASI) Score at EOT
Time Frame: End of Treatment (Up to 16 Weeks)
|
The PASI combines the assessment of the severity of lesions (scaling, redness and plaque thickness) and the area affected into a single score in the range of 0.0 (no disease) to 72.0 (maximal disease). The body is divided into four sections: (1) Head and neck; (2) Upper limbs; (3) Trunk (including axillae and groin); and (4) Lower limbs (including buttocks). The PASI score can vary in increments of 0.1 and range from 0.0 to 72.0, with higher scores representing greater severity of psoriasis. Percent change from baseline to EOT (up to 16 weeks) in PASI score was calculated by taking the PASI score at EOT and subtracting the baseline PASI score, then dividing by the baseline PASI score and multiplying by 100. |
End of Treatment (Up to 16 Weeks)
|
Percentage of Subjects Who Achieved Static Physician's Global Assessment (sPGA) Score of 0 or 1 at EOT
Time Frame: End of Treatment (Up to 16 Weeks)
|
The sPGA of psoriasis is scored on a 5-point scale, reflecting a global consideration of the redness, thickness and scaling across all psoriatic lesions. Average redness, thickness and scaling are scored separately over the whole body according to a 5-point severity scale (0 [no symptoms] to 4 [severe symptoms]). The total score is calculated as average of the 3 severity (redness, thickness and scaling) scores and rounded to the nearest whole number score to determine the sPGA score (0=cleared; 1=minimal; 2=mild; 3=moderate; and 4=severe). For this outcome measure, at EOT (up to 16 weeks), a score of 0 means no symptoms of psoriasis and a score of 1 means minimal symptoms of psoriasis. |
End of Treatment (Up to 16 Weeks)
|
Change From Baseline in Static Physician's Global Assessment (sPGA) Score at EOT
Time Frame: End of Treatment (Up to 16 Weeks)
|
The sPGA of psoriasis is scored on a 5-point scale, reflecting a global consideration of the redness, thickness and scaling across all psoriatic lesions. Average redness, thickness and scaling are scored separately over the whole body according to a 5-point severity scale (0 [no symptoms] to 4 [severe symptoms]). The total score is calculated as average of the 3 severity (redness, thickness and scaling) scores and rounded to the nearest whole number score to determine the sPGA score (0=cleared; 1=minimal; 2=mild; 3=moderate; and 4=severe). Change from baseline to EOT (up to 16 weeks) in sPGA score was calculated by taking the sPGA score at EOT and subtracting the baseline sPGA score. |
End of Treatment (Up to 16 Weeks)
|
Percent Change From Baseline in Psoriasis Body Surface Area (BSA) at EOT
Time Frame: End of Treatment (Up to 16 Weeks)
|
The total body surface area (BSA) affected by plaque-type psoriasis was obtained from the percentages of areas affected, including head, trunk, upper limbs and lower limbs. Each reported percentage was multiplied by its respective body region corresponding factor (head=0.1, upper limbs=0.2, trunk=0.3, lower limbs=0.4) and the resulting 4 values were added up to obtain the total psoriasis BSA (Range: 0 to 100). BSA (%)=0.1Sh+0.2Su+0.3St+0.4Sl, where S=body region surface area with psoriasis: h=head; u=upper limbs; t=trunk; l=lower limbs. Percent change from baseline to EOT (up to 16 weeks) in BSA was calculated by taking the EOT BSA and subtracting the baseline BSA, then dividing by the baseline BSA and multiplying by 100. A negative change from baseline at EOT indicates a reduction in the Psoriasis BSA compared to the baseline. |
End of Treatment (Up to 16 Weeks)
|
Change From Baseline in the Skindex-16 Overall Score at EOT
Time Frame: End of Treatment (Up to 16 Weeks)
|
Skindex-16 questionnaire contains 16 questions related to quality of life in subjects with skin disease. It consists of a short 16-item assessment completed by the subject, with each item rated on a 7-point Likert scale (0=never bothered to 6=always bothered). Each raw score is multiplied by 16.667 to transform all responses to a linear scale from 0 (no effect) to 100 (effect experienced all the time). Responses to the Skindex-16 are categorized into 3 subscales: symptom, emotional & functional; their respective scores are expressed in a linear scale from 0 to 100. Overall scale score is an average of 16 items expressed in a linear scale from 0 to 100. Change from baseline to EOT (up to 16 weeks) in the Skindex-16 Overall Score was calculated by taking the EOT Skindex-16 Overall Score and subtracting the baseline Skindex-16 Overall Score. A negative change from baseline at EOT indicates an improvement in the subject's condition compared to the baseline. |

A negative change from baseline at EOT indicates an improvement in the subject's condition compared to the baseline. |
End of Treatment (Up to 16 Weeks)
|
Change From Baseline in Itch Numeric Rating Scale (NRS) at EOT
Time Frame: End of Treatment (Up to 16 Weeks)
|
The Itch NRS is a validated, self-reported, instrument for measurement of itch intensity and subjects were asked to rate the intensity of their itch on an 11-point scale ranging from 0 (no itch) to 10 (worst itch imaginable); higher scores indicated greater itch intensity. The Itch NRS scores were recorded by the subject using the e-diary once daily from screening through the last visit. Change from baseline to EOT (up to 16 weeks) in the Itch NRS Score was calculated by taking the Itch NRS Score (weekly average) at EOT and subtracting the baseline Itch NRS Score (weekly average). |
