Maintenance Dosing Period: Number of Participants Who Achieved Static Physician Global Assessment (sPGA) of (0, 1)Week 20The sPGA is a physician's determination of the participant's psoriasis lesions overall at a given time point categorized by descriptions for induration, erythema, and scaling. For the analysis of responses, the participant's psoriasis is assessed as clear (0), minimal (1), mild (2), moderate (3), severe (4), or very severe (5). An sPGA assessed as either 0 or 1 represents a clinically meaningful response of minimal plaque severity or complete resolution of psoriasis.
Maintenance Dosing Period: Number of Participants Who Achieved at Least a 75% Improvement From Baseline in Psoriasis Area and Severity Index (PASI) Score (PASI 75) Improvement From Baseline in Psoriasis Area and Severity Index (PASI) Score (PASI 75)Week 20PASI combines assessments of the extent of body surface involvement in 4 regions (head & neck(h), trunk(t), arms(u), legs(l)) & severity of scaling (S), redness (R), & plaque induration/infiltration (thickness, T) in each region. Severity is rated for each index (R, S, T) on a 0-4 scale (0 for no involvement up to 4 for severe involvement): 0 = none, 1 = slight, 2 = mild, 3 = moderate, 4 = severe Fraction of total body surface area (BSA) affected is graded on a 0-6 scale (0 for no involvement to 6 for 90% - 100% involvement): 0 = 0% (clear), 1 = \>0% to \<10%, 2 = 10% to \<30%, 3 = 30% to \<50%, 4 = 50% to \<70%, 5 = 70% to 90%, 6 = 90% to 100%. Overall score ranges from 0 (no psoriasis) to 72 (most severe disease).

Maintenance Dosing Period: Change From Baseline in Percent of Body Surface Area (BSA) Involvement of Psoriasis Body Surface Area (BSA) Involvement of PsoriasisBaseline, Week 20Percentage involvement of psoriasis on each participants body surface area was assessed by the investigator on a continuous scale from 0% (no involvement) to 100% (full involvement), in which 1% corresponds to the size of the participant's hand (including palm, fingers and thumb).
Maintenance Dosing Period: Change From Baseline in Dermatology Life Quality Index (DLQI) Total ScoreBaseline, Week 20The DLQI is a simple, patient-administered, 10-question, validated, quality-of-life questionnaire that covers 6 domains, including symptoms and feelings, daily activities, leisure, work and school, personal relationships, and treatment. Response categories include not at all, a little,a lot, and very much, with corresponding scores of 0, 1, 2, and 3, respectively, and unanswered (not relevant) responses scored as 0. Totals range from 0 to 30 (the higher the score, the more quality of life is impaired) and a 5-point change from baseline is considered clinically relevant (Basra et al. 2008).

Generalized Pustular Psoriasis (GPP) Only: Change From Baseline on Generalized Pustular Psoriasis Severity IndexBaseline, Week 20GPP Severity Index was evaluated only for participants with pustular psoriasis at screening and at baseline. This is a composite score derived from the sum of scores for assessment of dermal symptoms, systemic symptoms, and laboratory findings (range, 0 to 17, with 17 representing severe symptoms). Skin symptoms were assessed by the score with the area of erythema (on a 0 to 3 scale), area of confluent pustules (on a 0 to 3 scale), and are of skin edema (on a 0 to 3 scale). The total score will be assessed (range, 0 to 9, with 9 representing severe symptoms). Systemic symptoms and laboratory findings were assessed by the score with fever (on a 0 to 2 scale), white blood cell (on a 0 to -2 scale), C-reactive protein (on a 0 to 2 scale) and Albumin (on a 0 to 2 scale). The total score will be assessed (range, 0 to 8, with 8 representing severe symptoms).
Maintenance Dosing Period: Change From Baseline in Psoriasis Scalp Severity Index (PSSI) in Participants With Scalp Involvement at BaselineBaseline, Week 20The scalp was assessed for erythema (redness), induration (hardness), and desquamation (shedding of skin) and percentage of area affected as follows: Erythema, Induration and Desquamation: 0 = Absent 1. = Slight 2. = Moderate 3. = Severe 4. = Severest Possible Percent of Scalp Involved: 1. = \<10% 2. = 10% - 29% 3. = 30% - 49% 4. = 50% - 69% 5. = 70% - 89% 6. = 90% - 100% The PSSI score is a composite score derived from the sum of the scores for erythema, induration and desquamation multiplied by the score for the extent of scalp area involved (percent of scalp involved). The range is 0 (no psoriasis) to 72 (Most severe Disease).
