• Baseline itch NRS score ≥ 6 in anogenital area.
• Prior use of topical corticosteroid.
• Participants who agree to discontinue all agents used by the participant to treat LS from the screening visit through the final safety follow-up visit, aside from rescue therapy as specified in "Concomitant therapy" in the protocol

• Need for receiving a live vaccine right before or during treatment with the study drug.
• Planned or expected major surgical procedure during the clinical study.
• Pregnant or lactating participants or those considering pregnancy during the period of their study participation.
• Participants unwilling to refrain from using prohibited medications during the clinical study.
• Patients who have been treated with systemic medications for other dermatologic conditions or itch within the past 4 months.
• Patients that undergone had physical treatment modalities, such as CO2 laser or radiofrequency microneedling to the anogenital region.
• Body weight <30 kg.
• Current treatment or treatment within 30 days or 5 half-lives (whichever is longer) before the baseline visit with another investigational medication or current enrollment in another investigational drug protocol.
• Previous treatment with nemolizumab.

• Any serious illness or medical, physical, or psychiatric condition(s) that, in the investigator's opinion, would interfere with full participation in the study, including administration of study drug and attending required study visits; pose a significant risk to the participant; or interfere with interpretation of study data.
• Any of the following clinical laboratory test results at screening:
• Liver function tests: serum AST or ALT (>3x upper limit of normal) in conjunction with serum bilirubin (>2x upper limit of normal)
• Positive serology test results at screening for HIV antibody.
• Positive serolgy test results at screening for tuberculosis (QuantiFERON®-TB Gold).
• History of acute or chronic active hepatitis B or C virus infection.
