Primære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Percent change from baseline in weekly average Peak Pruritus Numeric Rating Scale (PP-NRS) at week 24
Tidsramme: Baseline; Week 24
The PP-NRS is a single-item measure assessing itch on a scale from 0 ("no itch") to 10 ("worst imaginable itch"). Participants will complete the PP-NRS daily, rating their worst level of itch during the past 24 hours.
Baseline; Week 24
Percentage of patients achieving an Investigator Global Assessment for Prurigo Nodularis Stage (IGA PN-S) score of 0 or 1
Tidsramme: Baseline; Week 24
The percentage of patients achieving an IGA PN-S score of 0 or 1 with a ≥2-point reduction from baseline to Week 24. The IGA PN-S is a rating completed by the investigator during visits assessing the severity of the disease from 0 (Clear) to 4 (Severe)
Baseline; Week 24

Tidsramme
Percentage of subjects achieving at least a 4-point reduction from baseline in weekly average PP-NRS at Week 24
Tidsramme: Baseline; Week 24
The PP-NRS is a single-item measure assessing itch on a scale from 0 ("no itch") to 10 ("worst imaginable itch"). Participants will complete the PP-NRS daily, rating their worst level of itch during the past 24 hours.
Baseline; Week 24
Percent change from baseline in Dermatology Life Quality Index (DLQI) scores at week 24
Tidsramme: Baseline; Week 24
The DLQI is a 10-item questionnaire used to assess the impact of skin disease on the quality of life of the affected person. The 10 questions are scored from 0 to 3, giving a possible total score range from 0 (meaning no impact of skin disease on quality of life) to 30 (meaning maximum impact on quality of life). Completed by participants during study visits specified in the protocol.
Baseline; Week 24
Percent change from baseline in The Sleep Disturbance Numerical Rating Scale (SD-NRS) at week 24
Tidsramme: Baseline; Week 24
The SD-NRS is a single-item measure assessing sleep disturbance on a scale from 0 ("no sleep disturbance") to 10 ("worst possible sleep disruption"). Participants will complete the SD-NRS daily, rating their sleep quality.
Baseline; Week 24
Percent change from baseline in 5D-Pruritus Scale at week 24
Tidsramme: Baseline; Week 24
5-D pruritus' scale is a questionnaire assessing duration, degree, direction, disability, and distribution of the affected person's itch. Completed by participants during study visits specified in the protocol.
Baseline; Week 24
Percent change from baseline in Prurigo Activity Score (PAS) at week 24
Tidsramme: Baseline; Week 24
The PAS is a 7-item assessment completed by the investigator. The items of the PAS evaluate the type, number, distribution, size, and activity of skin lesions.
Baseline; Week 24
Percent change from baseline in HADS anxiety and depression scale at week 24
Tidsramme: Baseline; Week 24
The Hospital Anxiety and Depression Survey is a questionnaire that evaluates and monitors mental health in adults. Completed by participants during study visits specified in the protocol.
Baseline; Week 24
Percent change from baseline in Patient Global Impression of Change (PGIC) at week 24
Tidsramme: Baseline; Week 24
The PGIC is a questionnaire assessing overall satisfaction and perceived change due to treatment, ranging from "very much improved" to "very much worse". Completed by participants during study visits specified in the protocol.
