NCT05856526

Brief Summary

This study is open to people with a skin disease called Netherton syndrome (NS). People can join the study if they are 12 years or older. The purpose of this study is to find out whether a medicine called spesolimab helps people with NS. Participants are divided into a spesolimab and a placebo group. Placebo injections look like spesolimab injections but do not contain any medicine. Every participant has a 2 in 3 chance of being in the spesolimab group. In the beginning, participants get the study medicine as an injection into a vein. Afterwards, they get it as an injection under the skin every month. After 4 months, participants in the placebo group switch to spesolimab treatment. Participants are in the study for up to 3 years. During this time, they visit the study site up to 42 times. The doctors regularly check participants' NS symptoms. The results are compared between the groups to see whether spesolimab works. The doctors also regularly check participants' general health and take note of any unwanted effects.

Outcome Measures

Primary Outcomes (1)

  • IASI Response, Defined as a Decrease of at Least 50% Absolute Change in IASI Score From Baseline at Week 16 (Yes/No)

    Proportion of participants with an Ichthyosis Area Severity Index (IASI) response at Week 16 is reported. IASI response was defined as a decrease of at least 50% absolute change in IASI score from baseline at Week 16. Proportions were rounded to 3 decimal places. IASI is a composite score based on the global Congenital Ichthyosis Severity Instrument (CISI) score that captures differences in severity in different body regions as a function of their body surface area, and also standardizes the number of choices within the Likert scales for erythema and scaling. The score ranges from 0-48 (sum of a max score of 24 for erythema and 24 for scaling). A higher score means worse clinical severity. 95% confidence intervals (CI) are calculated using the method of Wilson.

    At baseline and at Week 16.

Secondary Outcomes (11)

  • Key Secondary Endpoint: IGA Response, Defined as a Decrease of at Least 1-grade Absolute Change in IGA Score From Baseline at Week 16 (Yes/No)

    Baseline and at Week 16 after start of study treatment administration.

  • IGA Score of 0 or 1 at Weeks 4, 8, 12 and 16 (Yes/No)

    At Week 4, at Week 8, at Week 12, at Week 16 after start of study treatment administration.

  • IASI Response, Defined as a Decrease of at Least 50% Absolute Change in IASI Score From Baseline at Weeks 4, 8, and 12 (Yes/No)

    At baseline and at Week 4, at Week 8, at Week 12 after start of study treatment administration.

  • IASI-E Subscore Response, Defined as a Decrease of at Least 50% Absolute Change in IASI-E Subscore at Weeks 4, 8, 12, and 16 (Yes/No)

    At baseline and at Week 4, at Week 8, at Week 12, at Week 16 after start of study treatment administration.

  • IASI-S Subscore Response, Defined as a Decrease of at Least 50% Absolute Change in IASI-S Subscore From Baseline at Weeks 4, 8, 12, and 16 (Yes/No)

    At baseline and at Week 4, at Week 8, at Week 12, at Week 16 after start of study treatment administration.

Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female patients, aged 12 years and older (weight minimum is 35kg).
  • Confirmed diagnosis of Netherton syndrome (NS) (causative SPINK5 mutations) at baseline (Visit 2).
  • At least moderate severity of erythema at baseline (visit 2) (Ichthyosis Area Severity Index (IASI) score ≥ 16 and IASI-Erythema (E) score ≥8) and ≥ 3 on Investigator Global Assessment (IGA) score.

  • Patients who have used systemic antibiotics within 2 weeks prior to randomisation
  • Patients who have received live vaccines within 4 weeks prior to randomisation
  • Patients who have received investigational products, biologics or immunoglobulins within 4 weeks or 5 half-lives (whichever is longer) prior to randomisation
  • Severe, progressive, or uncontrolled hepatic disease, defined as \>3-fold Upper Limit of Normal (ULN) elevation in Aspartate Aminotransferase (AST) or Alanine Aminotransferase (ALT) or alkaline phosphatase, or \>2-fold ULN elevation in total bilirubin

Data Sharing

IPD Sharing
Will not share

Clinical studies sponsored by Boehringer Ingelheim, phases I to IV, interventional and non-interventional, are in scope for sharing of the raw clinical study data and clinical study documents. Exceptions might apply, e.g. studies in products where Boehringer Ingelheim is not the license holder; studies regarding pharmaceutical formulations and associated analytical methods, and studies pertinent to pharmacokinetics using human biomaterials; studies conducted in a single center or targeting rare diseases (in case of low number of patients and therefore limitations with anonymization).
