Change From Baseline in Body Surface Area (BSA) Affected With Psoriasis at Week 16
Change from baseline in BSA affected with psoriasis at Week 16 will be reported. The BSA is a measurement of involved skin over the whole body. The overall BSA affected by psoriasis is estimated based on the participant's handprint (defined as the entire palmar surface of the hand including fingers).
Change From Baseline in Total Psoriasis Area and Severity Index (PASI) Score at Week 16
Change from baseline in PASI score at Week 16 will be reported. The PASI is a system used for assessing and grading the severity of psoriatic lesions and their response to therapy. In the PASI system, the body is divided into 4 regions: the head, trunk, upper extremities, and lower extremities. Each of these areas is assessed separately for erythema, induration and scaling, which are each rated on a scale of 0 to 4 that is none to maximum severity. The PASI produces a numeric score that can range from 0 to 72. A higher score indicates more severe disease.
Percentage of Participants who Achieve an Investigator's Global Assessment (IGA) Score of Cleared (0) at Week 16
Percentage of participants who achieve an IGA score of cleared (0) at Week 16 will be reported. The IGA documents the investigator's assessment of the participant's psoriasis. Overall lesions are graded for induration, erythema, and scaling. The participant's psoriasis is assessed as cleared (0), minimal (1), mild (2), moderate (3), or severe (4).
Percentage of Participants who Achieve a PASI 90 Response at Week 16

The PASI produces a numeric score that can range from 0 to 72. A higher score indicates more severe disease. A PASI 100 response is defined as 100% improvement in PASI score from baseline.
Percentage of Participants who Achieve a Scalp-Specific Investigator Global Assessment (ss-IGA) Score of Absence of Disease (0) or Very Mild Disease (1) at Week 16 Among Participants With an ss-IGA Score >=3 at Baseline
Percentage of participants who achieve a ss-IGA score of absence of disease (0) or very mild disease (1) at Week 16 among participants with an ss-IGA score >=3 at baseline will be reported. The ss-IGA instrument is used to evaluate the disease severity of scalp psoriasis. Scalp lesions are graded for induration, erythema, and scaling. The participant's scalp psoriasis is assessed as absence of disease (0), very mild disease (1), mild disease (2), moderate disease (3), or severe disease (4).
Percentage of Participants who Achieve a Static Physician's Global Assessment of Genitalia (sPGA-G) Score of Clear (0) or Minimal (1) at Week 16 Among Participants With a sPGA-G Score >=3 at Baseline
Percentage of participants who achieve a sPGA-G score of clear (0) or minimal (1) at Week 16 among participants with a sPGA-G score >=3 at baseline will be reported. The sPGA-G is used to evaluate the disease severity of genital psoriasis. Severity of genital psoriasis is determined by a combination of 3 plaque characteristics: erythema, elevation, and scale. The participant's severity of genital psoriasis is assessed as clear (0), minimal (1), mild (2), moderate (3), severe (4), and very severe (5).
Percentage of Participants who Achieve an Intertriginous IGA (i-IGA) Score of Clear (0) or Minimal (1) at Week 16 Among Participants With an i-IGA Score >=3 at Baseline
Percentage of participants who achieve an i-IGA score of clear (0) or minimal (1) at Week 16 among participants with an i-IGA score >=3 at baseline will be reported. The IGA used for the full body assessment has been adapted with descriptions of disease features that are more consistent with intertriginous psoriasis presentation. The intertriginous areas affected to be scored include the axillary, sub-mammary, abdominal fold, inguinal, and intergluteal cleft/peri-anal region (distinct from genital/perineum involvement). The participant's intertriginous areas affected are assessed as clear (0), minimal (1), mild (2), moderate (3), and severe (4).
Percentage of Participants who Achieve a Facial IGA (f-IGA) Score of Clear (0) or Minimal (1) at Week 16 Among Participants With an f-IGA Score >=3 at Baseline
Percentage of participants who achieve a f-IGA score of clear (0) or minimal (1) at Week 16 among participants with an f-IGA score >=3 at baseline will be reported. The IGA used for the full body assessment will be adapted for use, but only the face will be scored. The participant's facial psoriasis is assessed as clear (0), minimal (1), mild (2), moderate (3), and severe (4).
Change From Baseline in Psoriasis Symptom and Sign Diary (PSSD) Total Symptom Score at Week 16
Change from baseline in PSSD total symptom score at Week 16 will be reported. The PSSD includes patient-reported outcome (PRO) questionnaire designed to measure the severity of psoriasis symptoms and signs for the assessment of treatment benefit. The PSSD is a patient-reported outcome instrument that includes 11 items covering symptoms (itch, pain, stinging, burning and skin tightness) and participant observable signs (skin dryness, cracking, scaling, shedding or flaking, redness and bleeding) using 0 to 10 numerical rating scales for severity. Two sub scores are derived each ranging from 0 to 100: the psoriasis symptom score and the psoriasis sign score. A higher score indicates more severe disease.
