    <description>PP NRS is an 11-point scale (0 to10) where 0 is &quot;no itch&quot; and 10 is the &quot;worst itch imaginable&quot;.</description>

    <time_frame>Week 16</time_frame>
    <description>IGA is a 5-point scale used by the investigator or trained designee to evaluate the global severity of PN. The Investigator will review the participant's skin and give a score of 0 (Clear), 1 (Almost clear), 2 (Mild), 3 (Moderate), or 4 (Severe).</description>

    <description>An AE is defined as any untoward medical occurrence in a clinical study participant administered a medicinal product which does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not it is related to the medicinal (investigational) product.</description>

    <description>PAS will include a count of the number of lesions in a representative area and a calculated staging (stage 0 to stage 4) based on the percentage of lesions with excoriations/crusts and healed lesions compared to all lesions. PAS item 5a reflects the current itch/scratch activity. It is used to estimate what percentage of the pruriginous legions show excoriations/crusts. 100 percent (%) = All pruriginous lesions have excoriations/crusts.</description>

    <description>HADS is a 14-question validated questionnaire completed by the participant for each subscale (i.e. depression and anxiety). Question has a multiple choice answer which is scored between 0 and 3. Questions are identified as relating to anxiety (A) or depression (D) and a summation for each area is performed leading to a total score of 0 to 21 for each area. Scores of 0 to 7 are considered normal, 8 to 10 are borderline, and &gt;= 11 indicates clinical effects.</description>

measure: Change from Baseline in Wakefulness After Sleep Onset (WASO) Through Week 24
time frame: Baseline, through Week 24
description: Change from baseline in WASO, defined as the duration of wakefulness from the onset of persistent sleep. WASO is assessed with 3 questions: 1) How many times did you wake up due to the symptoms of prurigo nodularis (for example itching, burning), not counting the final time you woke up for the day? 2) In total, how long did the awakenings related to the symptoms of prurigo nodularis (for example itching, burning) last and 3) In total, how long did these awakenings related to other things last (for example to drink water, to go to the bathroom).
measure: Change from Baseline in Total Awake and Sleep Time Through Week 24
time frame: Baseline, through Week 24
measure: Change from Baseline in Sleep Efficiency Through Week 24
time frame: Baseline, through Week 24
description: The Sleep Efficiency is the ratio of total sleep time to time in bed. This shall be assessed by responses from the following questions from participant's sleep diary: 1) What time did you get into bed? 2) What time did you try to go to sleep? 3) How long did it take you to fall asleep? 4) What time did you wake up for the day? 5) What time did you get out of bed for the day?

time frame: Through Week 24
description: The DLQI is a validated 10-item questionnaire covering domains including symptoms/feelings, daily activities, leisure, work/school, personal relationships, and treatment. The participant will rate each question ranging from 0 (not at all) to 3 (very much) and score ranges from 0 to 30. A higher total score indicates a poorer quality of life (QoL).
