MeasureTime frameDescription
Change From Baseline in the Peak-Pruritus Numerical Rating Scale (PP-NRS) Score at Day 2 (24-hour Recall Period After First Application)Baseline; Day 2The intensity of pruritus (itch) was recorded daily using the PP-NRS (24-hour recall period). Participants were asked to assign a numerical score representing their itch at the worst moment during the previous 24 hours on a scale of 0 to 10, with 0 being no itch and 10 being the worst itch imaginable. Change from Baseline was calculated as the post-Baseline value minus the Baseline value. Baseline was defined as the average of all non-missing PP-NRS scores reported during the 7-day run-in period.

Change From Baseline in the Peak-Pruritus Numerical Rating Scale (PP-NRS) Score at Day 2 (24-hour Recall Period After First Application)

The intensity of pruritus (itch) was recorded daily using the PP-NRS (24-hour recall period). Participants were asked to assign a numerical score representing their itch at the worst moment during the previous 24 hours on a scale of 0 to 10, with 0 being no itch and 10 being the worst itch imaginable. Change from Baseline was calculated as the post-Baseline value minus the Baseline value. Baseline was defined as the average of all non-missing PP-NRS scores reported during the 7-day run-in period.

Time frame: Baseline; Day 2

Population: Modified Intent-to Treat (mITT) Population: all participants who had both a Baseline and at least 1 post-Baseline PP-NRS or modified PP-NRS (mPP-NRS) assessment within the treatment period. Only participants with available data were analyzed.

On Day 1, participants were asked to evaluate the current intensity of their itch at the time of assessment (i.e., prior to the morning study drug application, and 15 and 30 minutes and 1, 2, 4, 6, and 12 hours after the morning study drug application; the 12-hour evaluation occurred prior to the second daily study drug application) on a scale from 0 to 10, with 0 indicating no itch and 10 indicating the worst imaginable itch. Baseline was defined as the last non-missing assessment before or on Day 1 and prior to the first application of study drug (including unscheduled assessments). Confidence intervals were calculated using the Clopper-Pearson method.

Percentage of Participants Achieving at Least a 1-grade Decrease From Baseline in the PP-NRS Score From Day 2 Through Day 29

The intensity of pruritus (itch) was recorded daily using the PP-NRS (24-hour recall period). Participants were asked to assign a numerical score representing their itch at the worst moment during the previous 24 hours on a scale of 0 to 10, with 0 being no itch and 10 being the worst itch imaginable. Baseline was defined as the average of all non-missing PP-NRS scores reported during the 7-day run-in period.

The IGA-TS is defined as an IGA score of 0 or 1 with a ≥2-grade reduction from Baseline. The IGA of the current state of the disease is a 5-point morphological assessment of overall disease severity. 0, clear: no erythema or induration/papulation, no oozing/crusting; there may be minor residual discoloration. 1, almost clear: there may be trace faint pink erythema with almost no induration/papulation and no oozing/crusting. 2, mild: there may be faint pink erythema with mild induration/papulation and no oozing/crusting. 3, moderate: there may be pink-red erythema with moderate induration/papulation, and there may be some oozing/crusting. 4, severe: there may be deep or bright red erythema with severe induration/papulation and with oozing/crusting.
