ListOutcomeTime frameDescription
PrimaryPercentage of Participants With Greater Than or Equal to (>=) 4 Points Improvement (Reduction) From Baseline in Worst-Itch Numeric Rating Scale (WI-NRS) Scores at Week 12Baseline, Week 12
WI-NRS is a validated measure of itch severity. Participants were asked daily to rate the intensity of their worst pruritus (itch) over the past 24 hours, using a 11-point scale ranging from 0 (no itch) to 10 (worst imaginable itch). Higher scores indicated more severity. Percentage of participants with \>=4 points improvement (reduction) from baseline in WI-NRS scores at Week 12 is reported in this outcome measure.
SecondaryPercentage of Participants With >=4 Points Improvement (Reduction) From Baseline in WI-NRS Scores at Week 24Baseline, Week 24
WI-NRS is a validated measure of itch severity. Participants were asked daily to rate the intensity of their worst pruritus (itch) over the past 24 hours, using a 11-point scale ranging from 0 (no itch) to 10 (worst imaginable itch). Higher scores indicated more severity. Percentage of participants with \>=4 points improvement (reduction) from baseline in WI-NRS scores at Week 24 is reported in this outcome measure.
SecondaryPercentage of Participants With Investigator's Global Assessment For Prurigo Nodularis-Stage (IGA PN-S) Scores of 0 or 1 at Week 24At Week 24
IGA PN-S is an instrument used to assess the overall number and thickness of PN lesions at a given time point, as determined by the investigator. It consists of a 5-point scale ranging from 0 to 4 where 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate and 4 = severe. Higher scores indicate severe prurigo nodularis. In this outcome measure, percentage of participants with IGA PN-S score of either 0 (clear) or 1 (almost clear) has been reported.
SecondaryPercentage of Participants With Both an Improvement (Reduction) in WI-NRS by >=4 Points and an IGA PN-S Score of 0 or 1 From Baseline at Week 24Baseline, Week 24
WI-NRS is a validated measure of itch severity. Participants were asked daily to rate the intensity of their worst pruritus (itch) over the past 24 hours, using a 11-point scale ranging from 0 (no itch) to 10 (worst imaginable itch), higher scores indicated more severity. IGA PN-S assess the overall number and thickness of PN lesions at a given time point, as determined by the investigator. It consists of a 5-point scale ranging from 0 to 4 where 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate and 4 = severe. Higher scores indicated greater severity. Percentage of participants with both an improvement (reduction) in WI-NRS by \>=4 Points (from Baseline) and an IGA PN-S score of 0 or 1 were reported in this outcome measure.
SecondaryPercentage of Participants With IGA PN-S Scores of 0 or 1 at Week 12At Week 12
IGA PN-S is an instrument used to assess the overall number and thickness of PN lesions at a given time point, as determined by the investigator. It consists of a 5-point scale ranging from 0 to 4 where 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate and 4 = severe. Higher scores indicate severe prurigo nodularis. In this outcome measure, percentage of participants with IGA PN-S score of either 0 (clear) or 1 (almost clear) has been reported.
SecondaryPercent Change From Baseline in WI-NRS Scores at Week 24Baseline, Week 24
WI-NRS is a validated measure of itch severity. Participants were asked daily to rate the intensity of their worst pruritus (itch) over the past 24 hours, using a 11-point scale ranging from 0 (no itch) to 10 (worst imaginable itch). Higher scores indicated more severity. Least squares (LS) means and standard error (SE) were obtained from Analysis of covariance (ANCOVA) model.
SecondaryChange From Baseline in Health-related Quality of Life (HRQoL) as Measured by Dermatology Life Quality Index (DLQI) at Week 24Baseline, Week 24
DLQI is developed to measure dermatology specific HRQoL in adult participants. It comprises of set of 10 questions assessing the impact of skin disease on participants' HRQoL over the previous week. Responses to each question were assessed on a 4-point Likert scale ranged from 0 (not at all) to 3 (very much). Scores from all 10 questions added up to give total DLQI scores ranged from 0 (not at all) to 30 (very much), higher scores indicated more impact on quality of life. LS means and SE were obtained from ANCOVA model.
SecondaryChange From Baseline in Skin Pain-NRS at Week 24Baseline, Week 24
Skin Pain-NRS was used to measure skin pain intensity. Participants were asked daily to rate the intensity of their worst skin pain over the past 24 hours, using a 11-point scale ranging from 0 ("No pain") to 10 ("Worst possible pain"). Higher scores indicated more severity. LS means and SE were obtained from ANCOVA model.
SecondaryChange From Baseline in Sleep-NRS at Week 24Baseline, Week 24
Sleep-NRS was used to measure sleep intensity. Participants were asked to rate their sleep quality on their past night upon awakening, using a 11-point NRS ranging from 0 to 10, where 0 = worst possible sleep and 10 = best possible sleep. Higher scores indicated less severity. LS means and SE were obtained from ANCOVA model.
SecondaryChange From Baseline in Hospital Anxiety and Depression Scale (HADS) Total Score at Week 24Baseline, Week 24
HADS is a 14-item self-administered questionnaire that consists of 2 scales, one measuring anxiety (HADS-A), and the other measuring depression (HADS-D). Each subscale comprised of 7 items with a scoring range from 0 (less severity of anxiety and depression) to 21 (greater severity of anxiety and depression symptoms) for each subscale. The total HADS score ranges from 0 (less severity) to 42 (more severity), with a high score indicative of a severe anxiety and/or depression level. LS means and SE were obtained from ANCOVA model.
