Brief Summary:
The ichthyoses are a group of lifelong genetic disorders which share characteristics of generalized skin thickening, scaling and underlying cutaneous inflammation. There are no therapies based on growing understanding of what causes the disease. However, there have been recent discoveries of marked elevations in expression of interleukin-17A (IL-17A) and IL-17-related cytokines in the skin of individuals with ichthyosis, which may explain the inflammation. Investigators propose that IL-17-targeting therapeutics will safely suppress the inflammation and possibly the other features of ichthyosis, improving quality of life.

Condition or disease Intervention/treatment Phase
Ichthyosis Autosomal Recessive Congenital Ichthyosis Lamellar Ichthyosis Congenital Ichthyosiform Erythroderma Epidermolytic Ichthyosis Netherton Syndrome Drug: Secukinumab Drug: Placebo Phase 2

Detailed Description:
The ichthyoses are a group of lifelong genetic disorders which share characteristics of generalized skin thickening, scaling and underlying cutaneous inflammation. The vast majority are orphan disorders and are associated with extremely poor quality of life related to social ostracism from altered appearance, associated itchiness and discomfort, and functional limitations from the skin disease. Among the most common of these orphan disorders are autosomal recessive congenital ichthyosis (ARCI) with its phenotypic subsets of lamellar ichthyosis (ARCI-LI) and congenital ichthyosiform erythroderma (ARCI-CIE), epidermolytic ichthyosis (EI) and Netherton syndrome (NS). Therapy is time-consuming for patients or parents and is supportive, focusing on clearance of the scaling. There are no therapies based on growing understanding of what causes the disease. There have been recent discoveries of marked elevations in expression of interleukin-17A (IL-17A) and IL-17-related cytokines in the skin of individuals with ichthyosis, which may explain the inflammation. Psoriasis, another inflammatory skin disorder with redness and scaling, has now been shown to result from IL-17 pathway activation and IL-17A inhibition is the most effective therapy known to treat psoriasis. Investigators propose that IL-17-targeting therapeutics will safely suppress the inflammation and possibly the other features of ichthyosis, improving quality of life. In this long-term, open-label extension, Investigators propose to treat adults with ichthyosis and at least moderate erythema with subcutaneously administered anti-IL-17 antibody (secukinumab) and to serially assess clinical response to this therapy and its safety.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Reduction at Week 16 in the Ichthyosis Area Severity Index (IASI) [ Time Frame: 16 Weeks ]
    Primary Efficacy Endpoint. The IASI score was modelled after the Eczema Area and Severity Index (EASI) and Psoriasis Area and Severity Index (PASI), commonly used in clinical trials for atopic dermatitis and psoriasis, respectively. This scale measures erythema and scaling and has a range of 0-48 (sum of a max score of 24 for erythema and 24 for scaling). A higher score means worse clinical severity. Mean difference IASI total score at Baseline was compared to IASI total score at Week 16.

  2. Total Number of Bacterial or Fungal Mucocutaneous Infections Through Week 16 [ Time Frame: 16 weeks of secukinumab/placebo double blind followed by 32 week open label treatment ]
    Primary Safety Endpoint
