Primary | Percent Change From Baseline in Weekly Average of the Peak Pruritus Numeric Rating Scale (NRS) Score at Week 4 Using Last Observation Carried Forward (LOCF) Approach | Pruritus NRS is a scale used by the participants to report the intensity of their pruritus (itch) during the last 24 hours. Participants completed the assessment once daily at home in the evening. Participants were asked the following questions in their local language: 1) For average itch intensity: "on a scale of 0 to 10, with 0 being 'no itch' and 10 being 'worst itch imaginable', how would you rate your itch overall during the previous 24 hours?"; 2) For maximum itch intensity: "on a scale of 0 to 10, with 0 being 'no itch' and 10 being 'worst itch imaginable', how would you rate your itch at the worst moment during the previous 24 hours?". Where, higher score indicated worst imaginable itch. Missing values including those who took rescue medication were replaced by LOCF approach. | Baseline, Week 4 | |
Primary | Percent Change From Baseline in Weekly Average of the Peak Pruritus Numeric Rating Scale Score at Week 4 Using Multiple Imputation (MI) Method | Pruritus NRS is a scale used by the participants to report the intensity of their pruritus (itch) during the last 24. Participants completed the assessment once daily at home in the evening. Participants were asked the following questions in their local language: 1) For average itch intensity: "on a scale of 0 to 10, with 0 being 'no itch' and 10 being 'worst itch imaginable', how would you rate your itch overall during the previous 24 hours?"; 2) For maximum itch intensity: "on a scale of 0 to 10, with 0 being 'no itch' and 10 being 'worst itch imaginable', how would you rate your itch at the worst moment during the previous 24 hours?". Where, higher score indicated worst imaginable itch. Multiple imputation generated twenty-five sets of data with missing values imputed from observed data using linear regression. | Baseline, Week 4 | |

The scale ranges from 0 (strongly worsened pruritus) to 8 ([almost] no pruritus anymore), including intermediate marks for slightly improved/worsened, moderately improved/worsened, and rather improved/worsened. Participants recorded their DPS score in their local language, and completed the assessment 24, 48 and 72 hours after the first injection at baseline and at week 4 before the second injection. | After 24, 48, 72 hours of first Injection and before second injection (Week 4) | |

Secondary | Investigator Global Assessment (IGA) Score at Each Visit | IGA is a 5-point scale used by the investigator or trained designee to evaluate the severity of the disease ranging from 0 to 4 where, 0 = clear, 1= almost clear, 2 = mild, 3 = moderate and 4 severe. IGA corresponds to the overall assessment of the severity of prurigo including presence of crust and nodules or skin bleeding. Higher score indicated greater severity of disease. | Day 1 (Baseline), Weeks 4, 8, 12 and 18 | |
Secondary | Percentage of Participants Achieving Investigator Global Assessment Success (Defined as IGA= 0 [Clear] or IGA = 1 [Almost Clear] With Two-point Improvement From Baseline) at Week 12 | IGA is a 5-point scale used by the investigator or trained designee to evaluate the severity of the disease ranging from 0 to 4 where, 0 = clear, 1= almost clear, 2 = mild, 3 = moderate and 4 severe. IGA corresponds to the overall assessment of the severity of prurigo including presence of crust and nodules or skin bleeding. Higher score indicated greater severity of disease. | Week 12 |
