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 more common "orphan" forms of ichthyosis are autosomal recessive congenital ichthyosis (ARCI; includes lamellar ichthyosis/LI and congenital ichthyosiform erythroderma/CIE), Netherton syndrome (NS) and epidermolytic ichthyosis (EI). However, there are dozens of other syndromic and non-syndromic ichthyotic disorders as well. Therapy is time-consuming for patients or parents and is supportive, focusing on clearance of the scaling. There are no therapies based on our growing understanding of what causes the disease. We have recently found marked elevations in Th17/IL-23 pathway cytokines and chemokines in the skin of individuals with ichthyosis, most similar to the inflammatory pattern of psoriasis. While the significance of the high expression of Th17/IL-23 pathway genes across all forms of ichthyosis studied to date is unknown, the high expression of genes of the Th17/IL-23 pathway in psoriasis is thought to be causative for the disease manifestations. We propose that IL-12/IL-23 -targeting therapeutics will safely suppress the inflammation and possibly the other features of ichthyosis, improving quality of life. As a proof-of-concept study, we propose to treat children (6 years of age and higher) and adults with ichthyotic disorders with ustekinumab in an open-label trial to serially assess clinical response to and safety of ustekinumab for this group of disorders.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'minimumAge': '6 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Subject has provided informed consent; parental consent for patients under 18 years of age (plus assent for subjects age ≥ 12 and \\< 18).\n* Subjects are at least 6 years of age or older at the time of screening.\n* Before screening visit, females must be:\n\n * Postmenopausal, defined as\n\n ≥ 45 years of age with amenorrhea for at least 18 months, OR\n * ≥ 45 years of age with amenorrhea for at least 6 months and a serum FSH level \\> 40 IU/mL OR\n * Of childbearing potential, in which case she must satisfy at least one of the below:\n\nSurgically sterile (has had a hysterectomy or bilateral oophorectomy, tubal ligation, or otherwise be incapable of pregnancy), or\n\nIf heterosexually active, practicing a highly effective method of birth control, including hormonal prescription oral contraceptives, contraceptive injections, contraceptive patch, intrauterine device, double-barrier method (e.g., condoms, diaphragm, or cervical cap, with spermicidal foam, cream, film, gel or suppository), or male partner sterilization, consistent with local regulations regarding use of birth control methods for subjects participating in clinical trials, for a period of 16 weeks after the last administration of study agent,\n\nOR\n\nNot heterosexually active.
