treatment purpose

1) Male or female patients, aged 12 years and older (weight minimum is 35 kg)
2) Confirmed diagnosis of NS (SPINK5 causative mutations) at baseline
3) At least moderate severity of erythema at baseline (IASI score morethan equal to 16 and IASI-E score morethan equal to 8) and more than equal to 3 on IGA score
4) Signed and dated written informed consent and assent in accordance with ICH-GCP and local legislation prior to admission in the trial
5) Women of childbearing potential (WOCBP) must be ready and able to use highly effective methods of birth control per ICH M3 (R2) that result in a low failure rate of less than percent per year when used consistently and correctly. A list of contraception methods meeting these criteria is provided in the CTP as well as in the patient, parent(s) (or patient's legal guardian) information.

1) Patients who have used topical corticosteroids (medium to high, US class I-V), topical retinoids, topical calcineurin inhibitors or keratolytics within 1 week prior to randomisation
2) Patients who have used emollient on the area to be biopsied in the previous 24 hours
3) Patients who have used systemic retinoids, other systemic immunosuppressants, systemic corticosteroids or phototherapy within 4 weeks prior to randomisation
4) Patients who have used systemic antibiotics within 2 weeks prior to randomisation
5) Patients who have received live vaccines within 4 weeks prior to randomisation
6) Patients who have received investigational products, biologics or immunoglobulins within 4 weeks or 5 half-lives (whichever is longer) prior to randomisation
Relevant chronic or acute infections including active tuberculosis, human immunodeficiency virus (HIV) infection or viral hepatitis at the time of randomisation. A patient can be re-screened if the patient was treated and is cured from the acute infection
