Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Percent of Subjects Who Achieve a Physician Global Assessment (PGA) Score of Clear (0) or Almost Clear (1) With a Minimum 2-grade Improvement From Baseline at Week 12. Analyses Were Done Using Multiple Imputation | Baseline to Week 12 | The PGA is a clinical tool for assessing the current state/severity of a subject's psoriasis at a given timepoint. A static 5-point scale is used to grade lesions on the clinical characteristics of erythema, scaling, and plaque thickness/elevation. The PGA ranges from 0 to 4, and is calculated as Clear (0), Almost clear (1), Mild (2), Moderate (3), and Severe (4). Higher PGA scores represent more severe disease. Analyses were done using multiple imputation |
| Secondary | Percent of Subjects With ≥ 75% Improvement in Psoriasis Area and Severity Index (PASI) From Baseline at Week 12. Analyses Were Done Using Multiple Imputation. | Baseline to Week 12 | The Psoriasis Area and Severity Index (PASI) scoring system combines the assessment of lesion severity and extent of affected area into a single score: 0 (no disease) to 72 (maximal disease). The body is divided into 4 areas for scoring (head, arms, trunk, and legs). Each area is assessed for 3 signs: erythema (redness), induration (plaque thickness), and scale. The severity of each sign in each body area is assessed and scored independently using a 5-point scale, where 0=none, 1=slight, 2=mild, 3=moderate, 4=severe. Each area is also assessed for percent of skin involved: 0 = (0%), 1 = (1-\<10%), 2 = (10-\<30%), 3 = (30-\<50%), 4 = (50 -\<70%), 5 = (70-\<90%), 6 = (90-100%). The individual scores are multiplied by a weighted factor for each body region; the sum of these scores gives the overall PASI score. Higher scores indicate more severe disease. PASI is a static assessment made without reference to previous scores. Analyses were done using multiple imputation. |
| Secondary | Percent of Subjects With a PGA Score of 0 or 1 at Week 12. Analyses Were Done Using Multiple Imputation. | Baseline to Week 12 | The PGA is a clinical tool for assessing the current state/severity of a subject's psoriasis at a given timepoint. A static 5-point scale is used to grade lesions on the clinical characteristics of erythema, scaling, and plaque thickness/elevation. The PGA ranges from 0 to 4, and is calculated as Clear (0), Almost clear (1), Mild (2), Moderate (3), and Severe (4). Higher PGA scores represent more severe disease. Analyses were done using multiple imputation. |
| Secondary | Mean Change in Percent of Total Body Surface Area (%BSA) Affected From Baseline to Week 12 | Baseline to Week 12 | Assessment of BSA with psoriasis was estimated by means of the handprint method, where the full palmar hand of the participant (fully extended palm, fingers and thumb together) represented approximately 1% of the total BSA. Body regions are assigned specific number of handprints with percentage \[Head and neck = 10% (10 handprints), upper extremities = 20% (20 handprints), Trunk (including axillae and groin) = 30% (30 handprints), lower extremities (including buttocks) = 40% (40 handprints)\]. Estimates of the % involvement in each body region will be multiplied by the fraction of total body area to obtain the total %BSA involved by region and overall. |
| Secondary | Percent of Subjects With ≥90% Improvement in PASI Score From Baseline to Week 12. Analyses Were Done Using Multiple Imputation. | Baseline to Week 12 | The Psoriasis Area and Severity Index (PASI) scoring system combines the assessment of lesion severity and extent of affected area into a single score: 0 (no disease) to 72 (maximal disease). The body is divided into 4 areas for scoring (head, arms, trunk, and legs). Each area is assessed for 3 signs: erythema (redness), induration (plaque thickness), and scale.
