Clinical diagnosis of PN for at least 6 months with: • Pruriginous nodular lesions on upper limbs, trunk, and/or lower limbs; • At least 20 nodules on the entire body with a bilateral distribution 3. IGA score = 3 (based on the IGA scale ranging from 0 to 4, in which 3 is moderate and 4 is severe) at both the screening and baseline visits; 4. Severe pruritus defined as follows on the PP NRS: • At the screening visit (Visit 1): PP NRS score is = 7.0 for the 24-hour period immediately preceding the screening visit; • At the baseline visit (Visit 2): Mean of the daily intensity of the PP NRS score is = 7.0 over the previous week; 5. Female subjects of childbearing potential must agree to use at least 1 adequate and approved method of contraception throughout the study and for 12 weeks after the last study drug injection. Adequate and approved methods of contraception applicable for the subject and/or her partner are defined below: • True abstinence, when in line with the preferred and usual lifestyle of the subject. Periodic abstinence (eg, calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception; • Progestogen-only oral hormonal contraception; • Combination of male condom with cap, diaphragm, or sponge with spermicide (double barrier methods); • Combined (estrogen- and progestogen-containing) oral, intravaginal, or transdermal hormonal contraception; • Injectable or implanted hormonal contraception; • Intrauterine devices; • Bilateral tubal ligation or tube insert (such as the Essure system) at least 3 months before the study; • Vasectomy of male partner at least 3 months before the study 6. Female subjects of non-childbearing potential must meet 1 of the following criteria: • Absence of menstrual bleeding for 1 year prior to screening without any other medical reason; • Documented hysterectomy or bilateral oophorectomy at least 3 months before the study; 7. Subject is willing and able to comply with all of the time commitments and procedural requirements of the clinical study protocol, including daily diary recordings by the subject using an electronic handheld device provided for this study. 8. Read, understood and signed an informed consent form (ICF) before any investigational procedure(s) are performed. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 198 F.1.3 Elderly (>=65 years) no F.1.3.1 Number of subjects for this age range 42
