Intraamniotic Administrations of ER004 to Male Subjects With X-linked Hypohidrotic Ectodermal Dysplasia...
X-Linked Hypohidrotic Ectodermal Dysplasia (XLHED)This is an open-label, prospective, genotype-match controlled for primary estimand, non randomized, multicenter, international Phase 2 clinical trial designed to investigate the efficacy and safety of ER004 administered intraamniotically as a treatment for unborn XLHED male subjects.
Impact of Dysregulation of Core Body Temperature on Sleep in Patients With Hypohidrotic Ectodermal...
Hypohidrotic Ectodermal DysplasiaThe aim of the study is to compare sleep efficiency by means of actigraphy in patients with hypohidrotic ectodermal dysplasia with healthy controls. Sleep efficiency, assessed on actigraphy, sleep architecture assessed on on polysomnography, body temperature and urine melatonin levels will be compared between the patients with hypohidrotic ectodermal dysplasia with healthy controls.
Extension Study of XLHED-Affected Male Subjects Treated With EDI200 in Protocol ECP-002
X-linked Hypohidrotic Ectodermal DysplasiaThe goal of the ECP-002e extension study is to continue the evaluation of all EDI200-treated ECP-002 subjects up to age 10 yrs. No additional study drug administration is planned. The efficacy evaluations will incorporate growth and development parameters, frequency of infections and hospitalizations, and age-appropriate assessments of ectoderm-derived organ function. The safety evaluations will include physical examinations, adverse events and concomitant medication documentation, and laboratory testing. Funding Source - FDA OOPD
Phase 2 Study to Evaluate Safety, Pharmacokinetics, Immunogenicity and Pharmacodynamics/Efficacy...
X-Linked Hypohidrotic Ectodermal DysplasiaThis Phase 2 first-in-neonate EDI200 study will enroll treatment-naïve, XLHED-affected male newborns in the first two weeks of life. All subjects will meet entry criteria including documentation of an Ectodysplasin (EDA) mutation associated with XLHED. Following Baseline evaluations, EDI200 dosing will be initiated between day-of-life 2 and 14, with each study subject receiving 2 doses/week for a total of 5 doses. The study will enroll subjects in two cohorts with subjects in cohort 1 dosed at 3 mg/kg/dose, associated with partial efficacy, and cohort 2 dosed at 10 mg/kg/dose where enhanced efficacy was demonstrated in the most relevant preclinical model. Given the challenge of identifying families where the subject is yet to be born, it is expected that cohort size and time for recruitment will be variable.
A Phase 1, Open-label, Multicenter, Safety and Pharmacokinetic Study of EDI200
X-linked Hypohidrotic Ectodermal DysplasiaFollowing discussions with the FDA, a Phase 1 safety study is being initiated in X-Linked Hypohidrotic Ectodermal Dysplasia (XLHED)-affected adults to develop safety and exposure data for EDI200 in anticipation of dosing XLHED-affected neonates. Selecting XLHED-affected adults for this study provides a genetic match and biologic relevance to XLHED-affected neonates. Both males and females will be enrolled, providing safety experience with EDI200 that will inform the planned neonate study as well as supportive data for potential future trials of antenatal EDI200 administration.
Phenotypic Properties in Individuals Affected With XLHED
X Linked Hypohidrotic Ectodermal DysplasiaThe current study design incorporates two previously developed, non-invasive approaches to characterize the phenotype of individuals affected with XLHED.
Short Term Effects and Risks of Physical Exercise in Subjects With Hypohidrotic Ectodermal Dysplasia...
X-Linked Hypohidrotic Ectodermal DysplasiaExercise-induced Rise of Body TemperatureBecause of their lack of sweat glands individuals with hypohidrotic ectodermal dysplasia (HED) are at particular risk of life-threatening hyperthermia during exercise in a warm environment. In this study, the effects of physical exercise are investigated in boys and male adolescents with X-chromosomally inherited HED as well as age-matched controls, who undergo standardized exertion on a bicycle ergometer at ambient temperatures of 25°C and 30°C. Body core temperature during and after ergometry, heart rate, performance, and serum lactate as a marker of metabolic stress are measured. Subjects with HED are expected to show an endangering rise of body temperature in connection with physical exercise. To clarify, whether novel cooling devices may reduce the likelihood of overheating, the effects of such devices are evaluated at 30°C.
Evaluation of Phenotypic and Genetic Properties in Male Subjects Affected By Hypohidrotic Ectodermal...
X-linked Hypohidrotic Ectodermal DysplasiaHypohidrotic Ectodermal DysplasiaThe study proposes to enroll male subjects affected by Hypohidrotic Ectodermal Dysplasia (XLHED). The sweat duct images will be acquired with a CE marked skin-imaging device and the sweat rate will be measured using a CE marked pilocarpine iontophoresis and collection system. The technologies for both imaging of sweat ducts and the measurement of maximal sweat rate have been used safely and without adverse events in our prior studies involving HED/XLHED subjects. Furthermore, this study will assess the feasibility of developing a non-invasive screening tool that will enable detection of clinical signs of XLHED based on an analysis of a two dimensional frontal photograph.
Natural History and Outcomes in X-Linked Hypohidrotic Ectodermal Dysplasia
X-Linked Hypohidrotic Ectodermal DysplasiaThe proposed natural history study will enroll male and female patients, ages 36 months and younger, who have a diagnosis of XLHED based on genetic testing and who have not received an investigational study drug. The study protocol will include collection of all relevant medical history and documentation of clinical outcomes using age-appropriate, minimally invasive technologies. Data will be collected both retrospectively, back to pregnancy assessments that may be available, and prospectively through age 5 yrs.
Medical Record Review of Hypohidrotic Ectodermal Dysplasia Clinical Phenotype
Hypohidrotic Ectodermal DysplasiaX-Linked Hypohidrotic Ectodermal DysplasiaThis study is being done to collect information about people who have or may have Hypohidrotic Ectodermal Dysplasia (HED) or X-linked Hypohidrotic Ectodermal Dysplasia (XLHED). This study will allow Edimer Pharmaceuticals to know more about HED/XLHED so that hopefully the investigators can develop a drug to treat this condition. In this study Edimer will retrospectively review and abstract (summarize) medical records of people that have or may have HED/XLHED in order to further understand the natural history and disease characteristics.
