Clinical Trial Summary

Psoriasis (PsO) is a chronic disease characterized by marked inflammation of the skin that results in thick, red, scaly plaques. This study will assess how safe and effective risankizumab is in adult participants with moderate to severe genital psoriasis or moderate to severe scalp psoriasis. Adverse events and change in disease signs and symptoms will be monitored. Risankizumab (Skyrizi) is a drug being studied for the treatment of moderate to severe genital psoriasis or moderate to severe scalp psoriasis. Approximately 200 participants with moderate to severe genital psoriasis or moderate to severe scalp psoriasis will be enrolled across approximately 45 sites globally. The study will be broken up into 2 sub-studies by disease location, participants with moderate to severe genital psoriasis (Study G) and moderate to severe scalp psoriasis (Study S). In both sub-studies participants will receive subcutaneous (SC) injections of risankizumab during the 52 week treatment period, or SC injections of placebo risankizumab during the 16 week treatment period followed by SC injections of risankizumab during the 36 week treatment period, with an 8-week follow-up period after the 52 week treatment period. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Study-G: Percentage of Participants with Achievement of static Physician Global Assessment of Genitalia (sPGA-G) of 0 or 1	The sPGA-G is a 5-point score ranging from 0 to 4, with a larger score indicating greater severity, based on the physician's assessment of the average thickness, erythema, and scaling of psoriatic genital lesions.	Week 16
Primary	Study-S: Percentage of Participants with Achievement of Scalp Investigator Global Assessment (IGA) of 0 or 1	The scalp IGA is a measurement of overall scalp involvement by the investigator at the time of evaluation. The scalp IGA is a 5-point scale ranging from 0 (clear) to 4 (severe) incorporating an assessment of the severity of the 3 primary signs of the disease: erythema, scaling, and plaque elevation.	Week 16
Secondary	Study-G: Percentage of Participants with Achievement of static Physician Global Assessment of Genitalia (sPGA-G) of 0	The sPGA-G is a 5-point score ranging from 0 to 4, with a larger score indicating greater severity, based on the physician's assessment of the average thickness, erythema, and scaling of all psoriatic lesions.	Week 16
Secondary	Study-G: Percentage of Participants with Achievement of Dermatology Life Quality Index (DLQI) of 0 or 1	The DLQI is a self-administered, 10-question questionnaire covering 6 domains (symptoms and feelings, daily activities, leisure, work and school, personal relationships, treatment) and has a 1-week recall period. The response options range from 0 (not affected at all) to 3 (very much affected). This gives an overall range of 0 to 30 where lower scores mean better quality of life.	Week 16
Secondary	Study-G: Percentage of Participants with Achievement of Clinically Meaningful (>= 4-point) Improvement from Baseline on the Genital Psoriasis Itch Numerical Rating Scale (NRS) [Among Participants with a Baseline Score >= 4]	The scalp Itch NRS is a self-administered NRS that asks the patients to assess their scalp itch on a scale from 0 to 10 where 0 represents no itch and 10 represents worst imaginable itch.	Week 16
Secondary	Study-G: Percentage of Participants with Achievement of Genital Psoriasis Sexual Frequency Questionnaire (GenPs-SFQ) Item 2 score of 0 or 1 Among Participants with a Baseline score >= 2	The GenPs-SFQ is a patient-reported outcome(s) [PRO] measure to evaluate the impact of genital psoriasis symptoms on sexual frequency, using a 1-week recall period. It consists of 2 items that assess the impact of genital psoriasis symptoms on the frequency of sexual activity. Each item uses a Likert scale. Respondents are asked to answer the questions based on their psoriasis symptoms in the genital area. Genital area is defined as the labia majora (outer lip), labia minora (inner lip), and perineum (area between vagina and anus) for females; penis, scrotum, and perineum (area between the penis and anus) for males.	Week 16
Secondary	Study-S: Percentage of Participants with Achievement of Psoriasis Scalp Severity Index (PSSI 90)	PPSI 90 is defined as >= 90% improvement from baseline in PSSI. The physician will assess the severity of scalp psoriasis using the PSSI, which consists of an assessment of erythema, induration, and desquamation on a scale from 0 (none) to 4 (very severe) and the percentage of scalp involved on a scale from 0 (<10% of scalp involved) to 6 (90 to 100% of scalp involved). The composite score is calculated as the sum of the scores for erythema, induration and desquamation multiplied by the score recorded for the extent of scalp area involved. The PSSI ranges from 0 to 72.	Week 16
Secondary	Study-S: Percentage of Participants with Achievement of PSSI 75	PPSI 75 is defined as >= 75% improvement from baseline in PSSI. The physician will assess the severity of scalp psoriasis using the PSSI, which consists of an assessment of erythema, induration, and desquamation on a scale from 0 (none) to 4 (very severe) and the percentage of scalp involved on a scale from 0 (<10% of scalp involved) to 6 (90 to 100% of scalp involved). The composite score is calculated as the sum of the scores for erythema, induration and desquamation multiplied by the score recorded for the extent of scalp area involved. The PSSI ranges from 0 to 72.	Week 16
Secondary	Study-S: Change from Baseline in Psoriasis Symptom Scale (PSS)	The PSS is a 4-item PRO instrument that assesses the severity of psoriasis symptoms in patients with moderate to severe psoriasis, using a recall period of 1 day. The symptoms include pain, redness, itching and burning from psoriasis. Current symptom severity is assessed using a 5-point Likert-type scale ranging from 0 (none) to 4 (very severe).	Week 16
Secondary	Study-S: Percentage of Participants with Achievement of PSSI 100	PPSI 100 is defined as >= 100% improvement from baseline in PSSI. The physician will assess the severity of scalp psoriasis using the PSSI, which consists of an assessment of erythema, induration, and desquamation on a scale from 0 (none) to 4 (very severe) and the percentage of scalp involved on a scale from 0 (<10% of scalp involved) to 6 (90 to 100% of scalp involved). The composite score is calculated as the sum of the scores for erythema, induration and desquamation multiplied by the score recorded for the extent of scalp area involved. The PSSI ranges from 0 to 72.	Week 16
Secondary	Study-S: Percentage of Participants with Achievement of PSS of 0	The PSS is a 4-item PRO instrument that assesses the severity of psoriasis symptoms in patients with moderate to severe psoriasis, using a recall period of 1 day. The symptoms include pain, redness, itching and burning from psoriasis. Current symptom severity is assessed using a 5-point Likert-type scale ranging from 0 (none) to 4 (very severe).	Week 16
