| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | WI-NRS4 Response at Week 12 | 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. |
| Secondary | WI-NRS4 Response at Week 4 | Baseline; Week 4 | WI-NRS4 was defined as the percentage of participants achieving a ≥4-point improvement (reduction) in 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. |
| Secondary | Percentage of Participants With Overall-Treatment Success at Week 12 | Baseline; Week 12 | Overall-Treatment Success was defined as both a WI-NRS4 response and Investigator's Global Assessment for Stage of Chronic Prurigo Treatment Success (IGA-CPG-S-TS). IGA-CPG-S-TS was defined as an IGA-CPG-S score of 0 or 1 with a ≥2 grade improvement from baseline. The IGA-CPG-S is an overall severity rating of chronic prurigo on a scale of 0 to 4: 0, clear (no pruriginous lesions); 1, almost clear (rare palpable pruriginous lesions \[approximately 1-5 lesions\]); 2, mild (few palpable pruriginous lesions \[approximately 6-19 lesions\]); 3, moderate (many palpable pruriginous lesions \[approximately 20-100 lesions\]); 4, severe (abundant palpable pruriginous lesions \[over 100 lesions\]). |
| Secondary | Percentage of Participants With IGA-CPG-S-TS at Week 12 | Baseline; Week 12 | IGA-CPG-S-TS was defined as an IGA-CPG-S score of 0 or 1 with a ≥2 grade improvement from baseline. The IGA-CPG-S is an overall severity rating of chronic prurigo on a scale of 0 to 4: 0, clear (no lesions); 1, almost clear (rare palpable pruriginous lesions \[approximately 1-5 lesions\]); 2, mild (few palpable pruriginous lesions \[approximately 6-19 lesions\]); 3, moderate (many palpable pruriginous lesions \[approximately 20-100 lesions\]); 4, severe (abundant palpable pruriginous lesions \[over 100 lesions\]). |
| Secondary | WI-NRS4 Response at Day 7 | Baseline; Day 7 | WI-NRS4 was defined as the percentage of participants achieving a ≥4-point improvement (reduction) in 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. |
| Secondary | WI-NRS4 Response at Each Post-baseline Visit | Baseline; up to Week 52 | WI-NRS4 was defined as the percentage of participants achieving a ≥4-point improvement (reduction) in 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. |
| Secondary | DBVC Period: Change From Baseline in WI-NRS Score at Each Post-baseline Visit | Baseline; up to Week 12 | 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. |
| Secondary | OLE Period: Change From Baseline in WI-NRS Score at Each Post-baseline Visit | Baseline; up to Week 52 | 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. |
| Secondary | Time to ≥2-point Improvement From Baseline in WI-NRS Score | Baseline; up to Week 12 | 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.
