Treatment boosted ADAs: defined as participants with a positive ADA assay response at baseline and with at least a 4-fold increase in titer compared to baseline during the TE period (time from the first IMP administration to the last IMP administration + 14 weeks). Titer values were defined as low titer (< 1,000); moderate (1,000 <= titer <= 10,000) and high titer (> 10,000).

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. Probability of participants with an improvement (reduction) in WI-NRS at Week 24 was based on Kaplan-Meier estimates and was reported in this outcome measure.

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.

Change From Baseline in HRQoL, as Measured by DLQI at Week 12
Description
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.

Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious Adverse Events (TESAEs)
Description
An adverse event (AE) was defined as any untoward medical occurrence in a participant who received study drug and did not necessarily have to have a causal relationship with the treatment. Serious adverse events (SAEs) was defined as any untoward medical occurrence that at any dose: resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, was a medically important event. TEAEs were defined as AEs that developed, worsened or became serious during the treatment-emergent (TE) period (time from the first investigational medicinal product [IMP] administration to the last IMP administration + 14 weeks).
Time Frame
From the first IMP administration to the last IMP administration + 14 weeks (i.e., up to 36 weeks)
Title
Number of Participants With Treatment-emergent and Treatment Boosted Antidrug Antibodies (ADA)
Description
ADA response was categorized as: Treatment emergent and Treatment-boosted. Treatment emergent ADAs were defined as a participant with no positive assay response at baseline but with a positive assay response during the entire TEAE period. Treatment boosted ADAs: defined as participants with a positive ADA assay response at baseline and with at least a 4-fold increase in titer compared to baseline during the TE period (time from the first IMP administration to the last IMP administration + 14 weeks). Titer values were defined as low titer (< 1,000); moderate (1,000 <= titer <= 10,000) and high titer (> 10,000).
Time Frame
From the first IMP administration to the last IMP administration + 14 weeks (i.e., up to 36 weeks)

Participants must have a minimum of 20 PN lesions in total on both legs, and/or both arms and/or trunk, at Screening visit and Day 1 History of failing a 2-week course of medium-to-superpotent topical corticosteroids (TCS) or when TCS are not medically advisable Have applied a stable dose of topical emollient (moisturizer) once or twice daily for at least 5 out of the 7 consecutive days immediately before Day 1. Must be willing and able to complete a daily symptom eDiary for the duration of the study. Exclusion criteria: Participants were excluded from the study if any of the following criteria apply: Presence of skin morbidities other than PN and mild atopic dermatitis that may interfere with the assessment of the study outcomes. PN secondary to medications. PN secondary to medical conditions such as neuropathy or psychiatric disease. Within 6 months before the screening visit, or documented diagnosis of moderate to severe atopic dermatitis from screening visit to randomization visit. Severe concomitant illness(es) under poor control that, in the investigator's judgment, would adversely affect the participant's participation in the study. Severe renal conditions (eg, participants with uremia and/or on dialysis). Participants with uncontrolled thyroid disease. Active tuberculosis or non-tuberculous mycobacterial infection, or a history of incompletely treated tuberculosis unless documented adequately treated. Diagnosed active endoparasitic infections; suspected or high risk of endoparasitic infection, unless clinical and (if necessary) laboratory assessment have ruled out active infection before randomization. Active chronic or acute infection (except HIV) requiring treatment with systemic antibiotics, antivirals, antiprotozoals, or antifungals within 2 weeks before the screening visit and during the screening period. Known or suspected immunodeficiency. Active malignancy or history of malignancy within 5 years before the Baseline visit, except completely treated in situ carcinoma of the cervix, completely treated and resolved non-metastatic squamous or basal cell carcinoma of the skin.
