Active clinical trials for "Ichthyosis"

This prospective, randomized pilot study compares the use of a xenograft with PRP to a xenograft alone for chronic, nonhealing wounds.

Four rare genetic diseases, xeroderma pigmentosum (XP), Cockayne syndrome (CS), the XP/CS complex and trichothiodystrophy (TTD) have defective DNA excision repair although only XP has increased cancer susceptibility. We plan to perform careful clinical examination of selected patients with XP, XP/CS, CS, or TTD and follow their clinical course. We will obtain tissue (skin, blood, hair, buccal swabs) for laboratory examination of DNA repair and for genetic analysis. We hope to be able to correlate these laboratory abnormalities with the clinical features to better understand the mechanism of cancer prevention by DNA repair. Patients will be offered counseling and education for cancer control.

This study will examine microbes (e.g., bacteria, fungi, viruses) that live on human skin and how microbes contribute to health and disease. It will analyze healthy human skin and how the these microorganisms might change in patients with atopic dermatitis (AD), a skin condition also known as eczema. Healthy volunteers, as well as patients with moderate to severe eczema (AD), between 2 and 40 years of age may be eligible for this study. We also wish to enroll children and adults aged 2-40 who have been diagnosed with inherited immune disorders known as HIES (hyperimmunoglobulin-E syndrome), WAS (Wiskott-Aldrich syndrome), or DOCK8 immunodeficiency because they frequently have skin problems similar to AD. Eligible participants undergo the following tests and procedures: Medical family and medication history Skin examination Blood tests (research blood as well as serum IgE, and complete blood count) Skin samples to analyze microbes. Samples are obtained by the following methods: swabbing the skin with a cotton swab; scraping (scratching) the skin gently with a blade to remove only the outermost skin layers; and, only in adults, biopsy (surgical removal) of a small skin sample less than 1/4-inch (5 mm) in diameter. Nose swabs to analyze microbes. Patients with eczema may have photographs of their skin taken to help monitor the skin rashes. Participants may be contacted periodically for follow-up studies. Patients with atopic dermatitis may have additional skin samples collected to examine changes in the skin bacteria over time and during all of the stages of eczema. In addition, patients who have a flare of their eczema are asked to undergo a skin sample collection as soon as possible.

This will be a single-center, single-arm, non-interventional natural history study to evaluate the longitudinal clinical course, functional outcome measures, and candidate biomarkers for individuals with DNA repair disorders, including Cockayne syndrome (CS), xeroderma pigmentosum (XP), and trichothiodystrophy (TTD).

Ichthyosis is a group of genetic skin disorders that present with dry, thickened, scaly, or flaky skin. As of today, there is no cure or treatment. Doctors can only treat the dry skin with different types of emollients to soften the scale. A deeper understanding of this disease is required to develop better treatments. There are different types of cells and cell-produced signals (biomarkers) that are being studied in order to help find these new treatments. Looking at biomarkers has been successful in helping us to understand other skin disorders better. The purpose of this study is to determine which blood and skin biomarkers characterize ichthyosis. Hypothesis: We predict that the biomarkers correlating with disease activity in Netherton syndrome will be different than the biomarkers found to correlate with the lamellar and other ichthyosis phenotype.

The goal of this observational study is to conduct a prospective assessment of the individual Burden of 9 rare skin diseases to assess disability in the broadest sense of the term (psychological, social, economic and physical) for patients and/or families. Two types of indicators will be used to reach this objective : an individual burden score calculated based on a burden questionnaire created specifically, approved and designed to understand the tendency to changes in care and lifestyles. The burden questionnaire should be used by patients and/or their family themselves in self-assessment. a descriptive analysis of all resources (medical and non-medical) used by the family unit to manage the disease.

The goal of this study is to identify important biological pathways involved in a variety of ichtyosis, using transcriptomic and proteomic techniques, with the aim of guiding the development of new therapeutis.

Efficacy and Safety of imsidolimab in Participants with Ichthyosis

This is a phase 2 randomized, multi-center, double-blind, vehicle controlled, 90 day, safety, efficacy, and systemic exposure study followed by a 90 day open-label extension of trifarotene cream in adults and adolescents with autosomal recessive ichthyosis with lamellar scale.

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.
