Pre-Assignment Details

Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Participants who received Ixekizumab (ixe) and classified as responder (Resp, sPGA 0/1) in Induction (IND) were re-randomized to receive 80 mg ixe Q4W, Q12W or placebo (PBO) in Maintenance (MAIN) [Primary Population (Pop)]. Non-responders (Non-Resp, sPGA >1) in IND received 80 mg ixe Q4W, PBO Resp received PBO in MAIN (Secondary Pop).

^[1]	The sPGA is the physician's determination of the participant's Ps lesions overall at a given time point. Lesions were categorized by descriptions for induration, erythema, and scaling. Participants Ps were assessed as 0 (clear), 1 (minimal), 2 (mild), 3 (moderate), 4 (severe), or 5 (very severe).

WPAI-PSO is a self-administered, 6-item instrument used to assess the impact of Ps on productivity impairment within the past 7 days. WPAI-PSO has 4 domains: absenteeism, presenteeism (reduced productivity at work), an overall work impairment score and impairment in daily activities performed outside work. Four scores are derived as percentages: absenteeism, presenteeism (reduced productivity while at work), overall work impairment (absenteeism and presenteeism), and impairment in activities performed outside of work. Percentage = each score * 100. Greater scores indicate greater impairment.

The SF-36 is a self-reported instrument that measures the participant's health status during the previous 7 days. 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. The 8 domains are regrouped in the PCS and MCS scores. Scores range from 0 to 100, with higher scores indicating better levels of function and/or better health.
