5 Clinical Trials for Various Conditions
The ichthyoses are a family of genetic skin diseases characterized by dry, thickened, scaling skin. Dermatologists estimate that there are over twenty varieties of ichthyosis, with a wide range of severity and associated symptoms. This registry is designed to identify people in the United States with the ichthyoses and other related disorders and to collect information about their skin ailment and how it has affected them. The database is available for review by approved research applicants. The registry is confidential and provides investigators a way to share information about studies and trials with potential participants while maintaining participants' privacy. Although the Registry is closed to new enrollment, it is still maintained in order to provide information related to understanding the diagnosis, pathophysiology, and treatment of ichthyoses. Support for studies continues and inquiries from investigators are welcomed.
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.
The purpose of this study is to identify the genes responsible for certain scaling disorders and other inherited skin diseases and to learn about the medical problems they cause. In some cases, these may include problems affecting organs other than the skin, such as the eyes, teeth and bones. Patients with inherited skin disorders, including Darier's disease (keratosis follicularis), lamellar ichthyosis, epidermolysis bullosa, cystic acne, and others, and their relatives may be eligible for this study. Patients will have a medical history, physical examination with particular emphasis on the skin, and routine blood tests. Additional procedures for patients and unaffected relatives may include: 1. Blood sample collection 2. Dental exam with X-ray of the jaw 3. Eye examination 4. X-rays of the skull, ribs, chest, hands, feet, spine, arms, or legs 5. Bone density scan 6. Photographs of the skin 7. Skin biopsies (removal of a small tissue sample under local anesthetic) 8. Buccal sample (gentle brushing inside the cheek to collect a cell sample) for gene studies Patients who request the results of their gene testing will be provided this information.
Congenital ichthyosis (CI) is a large, heterogeneous family of inherited skin disorders of cornification resulting from an abnormality of skin keratinization, such as scaling and thickening of the skin. Treatment options include keratolytic agents, which can abruptly lead to extensive shedding or peeling of scales. PAT-001 primarily acts as a keratolytic agent; thus, making it a potential drug candidate for the treatment of skin disorders associated with hyperkeratinization, such as CI. The current study intends to evaluate the safety and tolerability of PAT-001 in patients with CI of either the Lamellar or X-Linked subtypes.
