WI-NRS4 Response at Week 12
Tidsram: Baseline; Week 12

WI-NRS4 was defined as the percentage of participants achieving a ≥4-point improvement (reduction) in Worst-Itch Numeric Rating Scale (WI-NRS) score from baseline. The WI-NRS is a patient-reported outcome comprised of a single item rated on a scale from 0 ("no itch") to 10 ("worst imaginable itch"). Participants assessed their worst level of prurigo nodularis-related itch during the past 24 hours on a scale of 0 to 10. The WI-NRS score for baseline was determined by averaging the 7 daily WI-NRS scores before Day 1 (i.e., Days -7 to -1). The by-visit WI-NRS score for post-baseline visits was determined by averaging the 7 daily WI-NRS scores before the visit day. Participants with missing Week 12 data for any reason, including treatment discontinuation (due to development of atopic dermatitis lesions or any other cause), were defined as nonresponders.

The extent and severity of prurigo nodularis was assessed via the PAS (version 1.2). The first 3 items are descriptive of the type, predominant type, distribution, and quantity of pruriginous lesions. The remaining 2 items of the PAS assess disease activity in terms of percentage (i.e., 0%, 1%-25%, 26%-50%, 51%-75%, and 76%-100%) of pruriginous lesions with excoriations/crusts on top (to reflect active scratching) and the percentage (i.e., 100%, 76%-99%, 51%-75%, 26%-50%, and 0%-25%) of healed pruriginous lesions in order to quantify change of prurigo nodularis skin lesions.

DBVC Period: Change From Baseline in the Dermatology Life Quality Index (DLQI) Total Score at Each Post-baseline Visit
Tidsram: Baseline; up to Week 12

The DLQI is a simple, 10-question, validated questionnaire to measure how much the skin problem has affected the participant over the previous 7 days. Each question was scored as: 3 (very much), 2 (a lot), 1 (a little), 0 (not at all or not relevant). The DLQI total score was calculated by summing the score of each question, resulting in a maximum of 30 and a minimum of 0. The higher the score, the more the quality of life was impaired. Total DLQI scores were categorized as follows: 0 to 1 (no effect), 2 to 5 (small effect), 6 to 10 (moderate effect), 11 to 20 (very large effect), and 21 to 30 (extremely large effect). Change from Baseline was calculated as the post-baseline visit minus the baseline visit.

DBVC Period: Change From Baseline in European Quality of Life 5 Dimensions 5 Level Version (EQ-5D-5L) Visual Analog Scale (VAS) Score at Each Postbaseline Visit
Tidsram: Baseline; up to Week 12

The EQ-5D-5L is a standardized instrument for use as a measure of health outcome. The EQ-5D-5L consists of 2 sections: the EQ-5D descriptive system and the EQ VAS. The descriptive system comprises 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 5 response levels, which are coded by single-digit numbers: 1 = no problems, 2 = slight problems, 3 = moderate problems, 4 = severe problems, 5 = unable to/extreme problems. The EQ VAS records the participant's self-rated health on a vertical VAS (0-100), on which the endpoints are labeled "the best health you can imagine" (100 score) and "the worst health you can imagine" (0 score). Change from Baseline was calculated as the post-baseline value minus the baseline value.

DBVC Period: Number of Participants With Any Treatment-emergent Adverse Event (TEAE)
Tidsram: up to Week 12

An adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not it is considered drug related. An AE can therefore have been any unfavorable or unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study cream. A TEAE was defined as any AE reported for the first time or the worsening of a pre-existing event after the first application of study drug.

DBVC Period: Number of Participants With Any ≥Grade 3 TEAE
Tidsram: up to Week 12

An AE was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not it is considered drug related. An AE can therefore have been any unfavorable or unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study cream. A TEAE was defined as any AE reported for the first time or the worsening of a pre-existing event after the first application of study drug. The severity of TEAEs was assessed using Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 Grades 1 through 5. The investigator made an assessment of intensity for each TEAE and assigned it to one of the following categories: Grade 1, mild; Grade 2, moderate; Grade 3, severe or medically significant but not immediately life threatening; Grade 4, life-threatening consequences; Grade 5, fatal.
