Outcome Measures
Primary Outcome Measures
- Number of Participants Achieving Static Physician Global Assessment (sPGA) of Genitalia (0,1) [Week 12]
sPGA of Genitalia score is based on a combination of erythema and the secondary features (plaque elevation and/or scale). For the analysis of responses, the participant's psoriasis was assessed as follows: 0 = clear,1 = minimal, 2 = mild, 3 = moderate, 4 = severe, 5 = very severe. sPGA of Genitalia (0,1) : A sPGA of Genitalia assessed as either 0 or 1.
Secondary Outcome Measures
- Number of Participants Achieving Overall sPGA (0,1) [Week 12]
The overall sPGA is the physician's global assessment of the participant's psoriasis (Ps) lesions at a given time point. Plaques were assessed for induration, erythema, and scaling, and an overall rating of psoriasis severity was given using the anchors of 0 = clear, 1 = minimal, 2 = mild, 3 = moderate, 4 = severe, 5 = very severe. Overall sPGA (0,1) : An overall sPGA assessed as either 0 or 1.
- Number of Participants With at Least a 3 Point Improvement in Genital Psoriasis Itch Numeric Rating Scale (NRS) Item Within the Genital Psoriasis Symptom Scale (GPSS) [Week 12]
GPSS is a participant-administered assessment of 8 symptoms: itch, pain, discomfort, stinging, burning, redness, scaling, and cracking. Each respondent was asked to answer the questions based on the psoriasis symptoms in his or her genital area. The overall severity for each individual genital psoriasis symptom is indicated by selecting the number from an Numeric Rating Scale (NRS) of 0 to 10 that best describes the worst level of each symptom in the genital area in the past 24 hours, where 0 (= no severity) and 10 (worst imaginable severity).
- Number of Participants Whose Frequency of Sexual Activity is Never or Rarely Limited by Genital Psoriasis, Utilizing the Genital Psoriasis Sexual Frequency Questionnaire (SFQ) Item 2 [Week 12]
The SFQ is a participant reported outcome measure to evaluate the impact of genital psoriasis symptoms on sexual frequency. It consists of 2 items that assess the impact of genital psoriasis symptoms on the frequency of sexual activity. Respondents were asked to answer the questions based on their psoriasis symptoms in the genital area. Item 2 assesses how often genital psoriasis symptoms limited the frequency of sexual activity with the following response options: 0 = never, 1 = rarely, 2 = sometimes, 3 = often, 4 = always. *The SFQ is also referred to as the GenPs-SFQ (genital psoriasis sexual frequency questionnaire).
- Number of Participants Whose Frequency of Avoiding Sexual Activity is Either Never or Rarely Limited by Genital Psoriasis in the Sexual Activity Avoidance Subscale Score of the Genital Psoriasis Sexual Impact Scale (GPSIS) [Week 12]
GPSIS is a participant reported outcome measure to evaluate the impact of genital psoriasis symptoms on sexual activity. The GPSIS Sexual Activity Avoidance Subscale includes 2 items: Item 1 asks whether the participant has been sexually active in the past week. (No due to other reasons = 1, No due to genital Ps = 5) Item 2 asks how often the participant avoided sexual activity in the past week due to Genital Psoriasis. (Never = 1, rarely = 2, Sometimes = 3, Often = 4)
- Change From Baseline in Dermatology Life Quality Index (DLQI) Total Score [Baseline, Week 12]
DLQI is a simple, participant-administered, 10 question, validated, quality-of-life questionnaire that covers 6 domains: 1) Symptoms and feelings 2) Daily activities 3) Leisure 4) Work and school 5) Personal relationships 6) Treatment. Response categories include: 0 = not at all; 1 = a little; 2 = a lot; 3 = very much; "not relevant" responses scored as "0" and total score range of 0 to 30; higher scores indicate poor quality of life. Least Square (LS) Mean was calculated using Mixed Model Repeated Measures (MMRM) model with treatment, baseline body surface area (BSA) category, baseline value, visit, treatment-by-visit, and baseline value-by-visit interactions as fixed effects.
- Change From Baseline in Modified Genital Psoriasis Area and Severity Index (mGPASI) Score [Baseline, Week 12]
mGPASI determines participants psoriasis severity in the genital region at a given time point yielding an overall score of 0 for no psoriasis to 72 for the most severe disease. scoring index incorporates the degree of erythema (or redness), induration (or thickness), and scaling) of the genital plaques as well as erosion, fissure, and/or ulcer as a product of the genital area involved. LS Mean was calculated using MMRM model with treatment, baseline BSA category, baseline value, visit, treatment-by-visit, and baseline value-by-visit interactions as fixed effects.
- Number of Participants With at Least a 2-Point Change in Patient's Global Assessment of Genital Psoriasis (PatGA-Genital) [Week 12]
Patient's Global Assessment of Genital Psoriasis (PatGA-Genital) is a participant-administered, single-item scale on which participants are asked to rank the severity of their genital psoriasis "today" by circling a number on a 0 to 5 NRS, as follows: from 0 (clear), no genital psoriasis; to 5 (severe).
- Change From Baseline on the Short-Form Health Survey (SF-36) Physical Component Summary (PCS) [Baseline, Week 12]
SF-36 is a participant-reported outcome measure evaluating a participant's health status. It comprises 36 items covering 8 domains: physical functioning, role physical, role emotional, bodily pain, vitality, social functioning, mental health, and general health. Items are answered on Likert scales of varying lengths. Items from 8 domains contribute to the PCS. The summary scores range from 0 to 100, with higher scores indicating better levels of function and/or better health. Least Squares Mean (LS Mean) was calculated using Analysis of covariance (ANCOVA) model with treatment, baseline BSA category, & baseline value and modified baseline observation carried forward (mBOCF) imputation method.
- Change From Baseline on the Short-Form Health Survey (SF-36) Mental Component Summary (MCS) [Baseline, Week 12]
SF-36 is a participant-reported outcome measure evaluating a participant's health status. It comprises 36 items covering 8 domains: physical functioning, role physical, role emotional, bodily pain, vitality, social functioning, mental health, and general health. Items are answered on Likert scales of varying lengths. Items from 8 domains contribute to the MCS. The summary scores range from 0 to 100, with higher scores indicating better levels of function and/or better health. Least Squares Mean (LS Mean) was calculated using Analysis of covariance (ANCOVA) model with treatment, baseline BSA category, & baseline value and modified baseline observation carried forward (mBOCF) imputation method.
- Change From Baseline in Genital Psoriasis Symptom Scale (GPSS) Total Score and Individual Items [Baseline, Week 12]
GPSS is a participant's-administered assessment of 8 symptoms: itch, pain, discomfort, stinging, burning, redness, scaling, and cracking. Each respondent was asked to answer the questions based on the psoriasis symptoms in his or her genital area. The overall severity for each individual genital psoriasis symptom is indicated by selecting the number from an Numeric Rating Scale (NRS) of 0 to 10 that best describes the worst level of each symptom in the genital area in the past 24 hours, where 0 (no severity) and 10 (worst imaginable severity). total score ranges from 0 (no severity) - 80 (worst imaginable severity) LS Mean was calculated using MMRM model with treatment, baseline BSA category, baseline value, visit, treatment-by-visit, and baseline value-by-visit interactions as fixed effects.
- Number of Participants Achieving sPGA of Genitalia (0,1) at Week 12 by Treatment-Emergent Anti-Drug Antibody (TE-ADA) Status and by Neutralizing Antibody (NAb) Status [Week 12]
sPGA of Genitalia score is based on a combination of erythema and the secondary features (plaque elevation and/or scale). For the analysis of responses, the participant's psoriasis was assessed as follows: 0 = clear,1 = minimal, 2 = mild, 3 = moderate, 4 = severe, 5 = very severe. sPGA of Genitalia (0,1) : A sPGA of Genitalia assessed as either 0 or 1.
