| Percentage of Participants Achieving a Static Physician's Global Assessment (sPGA) of Clear (0) or Almost Clear (1) With a ≥2-Point Decrease from Baseline at Week 16 | The sPGA is a 5-point scale of an average assessment of all psoriatic lesions based on erythema, scaling, and induration. The average of the 3 scales, rounded to the nearest whole number, is the final sPGA score. The sPGA score ranges from 0 to 4 (0 = Clear; 1 = Almost clear; 2 = Mild; 3 = Moderate; 4 = Severe). Higher scores indicate more severe disease activity. 'Clear' and 'Almost clear' will include all participants who score a 0 or 1. | Baseline, Week 16 |
| Percentage of Participants Achieving ≥75% Improvement from Baseline in Psoriasis Area and Severity Index (PASI) Score at Week 16 | PASI is a measure of the average redness, thickness, and scaliness of psoriatic skin lesions (each graded on a 0 to 4 scale; 0 = none to 4 = very severe), weighted by the area of involvement (head, upper extremities, trunk, and lower extremities). The PASI produces a numeric score that can range from 0 to 72, with higher PASI scores denoting more severe disease activity. Percentage of participants showing at least 75% improvement in PASI score relative to baseline PASI score will be reported. | Baseline, Week 16 |

| Change from Baseline in Nail Psoriasis Severity Index (NAPSI) at Week 16 and Week 52 Among Participants with Nail Involvement at Baseline | The NAPSI quantifies severity of nail psoriasis by evaluating the presence or absence of psoriatic manifestations on the nail matrix (pitting, leukonychia, red spots on lunula, crumbling) and nail bed (onycholysis, splinter hemorrhages, subungual hyperkeratosis, oil drop [salmon patch dyschromia]). Each nail will be scored for both nail matrix and nail bed psoriasis for each quadrant (ranging from 0 [absence of psoriasis] to 4 [presence of psoriasis in all 4 quadrants]). The total NAPSI score equals the sum of scores for all of the finger nails evaluated and ranges from 0 to 80. Higher scores indicate more severe psoriasis. | Baseline, Week 16 and Week 52 |
| Change from Baseline in Body Surface Area (BSA) Affected by Psoriasis at Week 16 and Week 52 | Psoriasis BSA will be assessed by means of the handprint method, where the surface of the palm and 5 digits of the participant's hand represents 1% BSA. The sum of handprints equates to the total surface area of involvement. | Baseline, Week 16 and Week 52 |
| Percentage of Participants with Generalized Pustular Psoriasis Who Achieve a Generalized Pustular Psoriasis Global Assessment (GPPGA) Pustulation Subscore of No Visible Pustules (0) at Week 16 and Week 52 | GPPGA is common endpoints in clinical studies of Generalized Pustular Psoriasis (GPP), and is skin-based scoring systems. The GPPGA is a clinician assessment of overall GPP severity based on a modified PGA, and the severity of pustules, erythema, and scaling of GPP lesions will be assessed. The five grades of severity for erythema, scaling, and pustulation correspond to 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate, and 4 = severe. The GPPGA score is based on averaging the individual scores for erythema, scaling, and pustulation ranging from 0 to 4. Higher scores indicate more severe GPP. | Week 16 and Week 52 |

The GPPGA is a clinician assessment of overall GPP severity based on a modified PGA, and the severity of pustules, erythema, and scaling of GPP lesions will be assessed. The five grades of severity for erythema, scaling, and pustulation correspond to 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate, and 4 = severe. The GPPGA score is based on averaging the individual scores for erythema, scaling, and pustulation ranging from 0 to 4. Higher scores indicate more severe GPP. | Week 16 and Week 52 |
| Percentage of Participants with Generalized Pustular Psoriasis Who Achieve a GPPGA of Clear (0) at Week 16 and Week 52 | GPPGA is common endpoints in clinical studies of Generalized Pustular Psoriasis (GPP), and is skin-based scoring systems. The GPPGA is a clinician assessment of overall GPP severity based on a modified PGA, and the severity of pustules, erythema, and scaling of GPP lesions will be assessed. The five grades of severity for erythema, scaling, and pustulation correspond to 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate, and 4 = severe. The GPPGA score is based on averaging the individual scores for erythema, scaling, and pustulation ranging from 0 to 4. Higher scores indicate more severe GPP. | Week 16 and Week 52 |
| Percentage of Participants with Generalized Pustular Psoriasis Who Achieve ≥75% Improvement from Baseline in Generalized Pustular Psoriasis Area and Severity Index (GPPASI) Score at Week 16 and Week 52 | GPPASI is common endpoints in clinical studies of GPP and is skin-based scoring systems. GPPASI is a modified composite index and an adaptation of the PASI score. The induration component has been substituted with a pustule component, with an overall score range from 0 (least severe) to 72 (most severe). Higher scores indicate more severe GPP. The five grades of severity for erythema, scaling, and pustulation correspond to 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate, and 4 = severe. The score for each body region is calculated (the product of the sum of severity scores and its corresponding BSA score for erythema, scaling, and pustulation, multiplied by a weighting factor for each body region) and then the total GPPASI score determined (the sum of the individual scores from all body regions. | Weeks 16 and Week 52 |
| Change from Baseline in Japanese Dermatological Association Severity Index (JDASI) Score at Week 16 and Week 52 for Participants with Generalized Pustular Psoriasis | The Japanese Dermatological Association severity index (JDASI) assesses the systemic symptoms by laboratory changes. With the JDASI the skin is evaluated using three criteria (1) erythema area (overall), (2) erythema area with pustules and (3) oedema area. Scoring ranges from 3 to 0 (severe, moderate, mild, none) with a maximum of nine points. For systemic involvement pyrexia, white blood cell count, C reactive protein (CRP) and serum albumin with scores ranging from 2 to 0 (maximum 8 points) are assessed. The total JDASI score of GPP is the sum of both categories and categorizes as severe (17-11 points), moderate (10-7 points) or mild (0-6 points). Higher scores indicate more severe GPP. | Week 16 and Week 52 |
