The main aim of this study is to assess real-world effectiveness of nemolizumab in Prurigo nodularis (PN) as measured by investigator and patient reported outcome (PRO) in clinical practice at Month 6.
Participants who, according to the treating physician's decision and in line with the local package label, are newly initiated on nemolizumab (Nemluvio®) for the treatment of PN.
Participants greater than or equal to (>=) 18 years of age.
Participants who signed the written informed consent form (ICF).
Have contraindication(s) for the use of nemolizumab (Nemluvio®) according to the local package label;
Participants who received treatment with a drug under clinical development/ investigation within 3 months prior to baseline.
Participants who received nemolizumab previously.
Participants who are mentally, physically, or linguistically unable to understand the content of the ICF and/or to complete the study questionnaires.
The clinical decision for treatment with nemolizumab has to be made by the physicians independently of the participation in this NIS and prior to the informed consent process. Participants greater than or equal to (\>=) 18 years of age will be eligible for the trial.

Investigator Global Assessment-chronic Prurigo (IGA-CPG stage) at Month 6
The IGA-CPG stage is an instrument used to assess the overall number and thickness of chronic prurigo lesions at a given time point, as determined by the physician. In this scale, nodules, papules, plaques, and other PN lesions are defined as pruriginous lesions or chronic prurigo lesions. A single score will be determined by the physician as follows: 0 (clear), 1 (almost clear), 2 (mild), 3 (moderate), or 4 (severe). A higher score indicates severe chronic prurigo.
Peak Pruritus Numerical Rating Scale (PP NRS) at Month 6
The PP NRS is a single-question validated PRO assessment that participants will use to report the maximum intensity of their pruritus (itch). The PP NRS consists of the following question: "On a scale of 0 to 10, with 0 being 'no itch' and 10 being the 'worst itch imaginable', how would you rate your itch at the worst moment during the previous 24 hours?". Here, a lower score indicates a better outcome.
Investigator Global Assessment-chronic Prurigo (IGA-CPG stage) Up to Month 12
The IGA-CPG stage is an instrument used to assess the overall number and thickness of chronic prurigo lesions at a given time point, as determined by the physician. In this scale, nodules, papules, plaques, and other PN lesions are defined as pruriginous lesions or chronic prurigo lesions. A single score will be determined by the physician as follows: 0 (clear), 1 (almost clear), 2 (mild), 3 (moderate), or 4 (severe). A higher score indicates severe chronic prurigo.
Prurigo Activity Score (PAS) Up to Month 12
The PAS is a physician-assessed tool to monitor the distribution and activity of chronic prurigo lesions. This includes a count of the number of lesions in a representative area and a calculated staging (stage 0 to stage 4) based on the percentage of lesions with excoriations/crusts and healed lesions compared to all lesions. A higher score indicates higher level of activity.
Peak Pruritus Numerical Rating Scale (PP NRS) Up to Month 12
The PP NRS is a single-question validated PRO assessment that participants will use to report the maximum intensity of their pruritus (itch). The PP NRS consists of the following question: "On a scale of 0 to 10, with 0 being 'no itch' and 10 being the 'worst itch imaginable', how would you rate your itch at the worst moment during the previous 24 hours?". Here, a lower score indicates a better outcome.
Sleep Disturbance Numerical Rating Scale (SD NRS) Up to Month 12
The SD NRS is a single-item PRO for quantifying sleep disturbance that has been validated in PN participants. The SD NRS consists of the following question: "On a scale of 0 to 10, with 0 being 'no sleep loss related to the symptoms of my skin disease (prurigo nodularis)' and 10 being 'I did not sleep at all due to the symptoms of my skin disease (prurigo nodularis)', how would you rate your sleep last night". Here, a lower score indicates a better outcome.
