Study summary

Following 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.

Read the detailed description

The Phase 1 study will enroll two cohorts of 3 XLHED-affected adults each, for a total of 6 subjects. The size and scope of the study design are consistent with a drug development program in an ultra-rare disease and supported by the absence of safety concerns in a GLP non-human primate toxicology study. All subjects must meet entry criteria including documentation of an EDA mutation. Mirroring the conditions of use anticipated for the XLHED-affected newborn study, the adult cohort study incorporates a multiple-dose regimen associated with maximal efficacy in the newborn canine model. Primary outcome measures will be safety, tolerability, immunogenicity and pharmacokinetics (PK). While current data does not support a likelihood of clinical benefit for the XLHED-affected adult subjects, assays of pharmacodynamic/biologic activity are incorporated into the study design as exploratory objectives.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Males and females of child-bearing age, age 18-40 years
  2. Weight between 45 and 90 kg and a (BMI) from 18 to 29 kg/m2 (calculated using the following formula: weight in kilograms/(height in meters)2)
  3. Both males and females must be documented (via genetic testing) to carry an EDA mutation associated with XLHED; or have the clinical signs and symptoms associated with HED and/or a family history of HED and provide a blood sample to be sent for genetic testing that confirms an EDA mutation associated with XLHED
  4. No major medical issues that the investigator considers to be a of participation
  5. No scalp shaving in the month prior to first dose (males only)
  6. Women must use a "highly effective" method of throughout the trial. Highly effective methods of birth control are defined as those, alone or in combination, which result in a low failure rate (i.e. less than 1% per year) when used consistently and correctly. These methods include implants, injectables, oral contraceptives, some intrauterine contraceptive devices, sexual abstinence, tubal ligation or a vasectomized partner.
  7. No treatment with an drug within the last three months
  8. Signed written

Exclusion criteria

Exclusion Criteria:

  1. Women who are pregnant (confirmed via urine pregnancy test) or breastfeeding at screening or planning to become pregnant at any time during the study period
  2. Known history of surface antigen (HBsAg) or (HCV) antibody
  3. Known history of infection
  4. Known to pilocarpine or pilocarpine-like muscarinic agonists
  5. Known hypersensitivity to lidocaine or lidocaine-like agents
  6. Presence of pacemakers
  7. Subjects who are not able or are not willing to comply with the procedures of this protocol
  8. Subject has a condition which in the opinion of the investigator would not allow for safe conduct of the study
Terms in these criteria, in plain language(9)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
