Phase 2 Study to Evaluate Safety, Pharmacokinetics, Immunogenicity and Pharmacodynamics/Efficacy of EDI200 in Male Infants With X-Linked Hypohidrotic Ectodermal Dysplasia (XLHED) — ECP-002

X-Linked Hypohidrotic Ectodermal Dysplasia Clinical Trial

Official title:
A Phase 2 Open-label, Dose-escalation Study to Evaluate the Safety, Pharmacokinetics, Immunogenicity and Pharmacodynamics/Efficacy of EDI200, an EDA-A1 Replacement Protein, Administered to Male Infants With X-Linked Hypohidrotic Ectodermal Dysplasia (XLHED)

Status Completed

Clinical Trial Summary

This 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.

Clinical Trial Description

This 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 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. This dosing regimen mirrors that used to enhance efficacy in the dog XLHED model, considered to be most relevant to the clinical study design. 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. The sponsor anticipates enrollment and dosing of 6-10 subjects over a 12-18 month period, 3-5 subjects per cohort. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
