Trial summary

This study in affected Hypohidrotic Ectodermal Dysplasia (HED) males and unaffected male controls, age 1 year and up, will use minimally invasive devices to image sweat ducts in intact skin, to measure stimulated sweat rate, and in a subset of subjects to collect clipped scalp hair samples for RNA analysis.

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 1 year and older
  • Men only
  • Healthy volunteers accepted
  • Child, Adult, Older adult

Study population: Attendees of the National Foundation for Ectodermal Dysplasia's (NFED) 2011 Annual Family Conference

Who may be able to join

  • Registered and attending the 2011 NFED Family Conference;
  • One year of age or greater;
  • Conform to one of the following requirements for providing informed consent/assent:
  • if more than 18 years of age, subjects must provide signed informed consent;
  • if less than 18 years of age and it is determined that the subject is capable of providing assent, both the assent of the subject and consent of the parent(s) or guardian of that subject must be granted. Under this condition, both parents of the subject should give their permission, unless 1 parent is deceased, unknown, incompetent, or not available;

  • As described in Section 3.2 above, subjects must meet one of the following criteria:
  • Male subjects with the clinical characteristics of HED, including at least a history of decreased sweating and either abnormal teeth (fewer permanent teeth, teeth are smaller than average and often have conical crowns), and/or sparseness of scalp and body hair (Male HED subjects with an affected sibling also enrolling in the study will be given priority to be in the study);
  • Healthy male controls, i.e. either unaffected male family members or unaffected male volunteers.

Who cannot join

  • Known hypersensitivity to pilocarpine or pilocarpine-like muscarinic agonists;
  • Known hypersensitivity to lidocaine or lidocaine like agents;

About this study

Official title: Evaluation of Phenotypic and Genetic Properties in Male Subjects Affected By Hypohidrotic Ectodermal Dysplasia: Intrafamilial Variation

This study in affected Hypohidrotic Ectodermal Dysplasia (HED) males and unaffected male controls, age 1 year and up, will use minimally invasive devices to image sweat ducts in intact skin, to measure stimulated sweat rate, and in a subset of subjects to collect clipped scalp hair samples for RNA analysis. This study is descriptive in nature and is intended to assess the ability to use innovative approaches to generate data from subjects over a wide age spectrum, with particular emphasis on phenotype variability between male siblings (same mutation).

Read the detailed description

This pilot study in affected HED males and unaffected male controls, age 1 year and up, will use minimally invasive devices to image sweat ducts in intact skin, to measure stimulated sweat rate, and in a subset of subjects to collect clipped scalp hair samples for RNA analysis. This study is descriptive in nature and is intended to assess the ability to use innovative approaches to generate data from subjects over a wide age spectrum, with particular emphasis on phenotype variability between male siblings (same mutation). To this end, priority will be given to families that contain multiple affected siblings (i.e. two brothers). Summary data will be generated for the various groups tested, but no power calculations are involved.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Use skin assessment techniques to characterize skin properties in male subjects affected by HED compared with healthy controls, including determination of the number of sweat ducts and the rate of sweating

    Day 1

    Measured: Day of study conduct

Secondary outcomes (4)
  1. Collecting demographic and clinical status information in male subjects affected by HED using a medical questionnaire

    Study Day 1

    Measured: Day of study conduct

  2. Assessment of intrafamilial phenotypic variability in families with multiple HED-affected male siblings

    Study Day 1 - Comparison of sweat duct counts, sweat rate and hair analysis among HED-affected male siblings

    Measured: Day of study conduct

  3. Evaluation of hair RNA profiles in samples from HED and unaffected male controls

    Study Day 1 -This is a novel use of the RNASeq technology and will follow the protocol provided by an expert in the field, Dr. Benjamin Yu. The hairs will be cut not plucked from the occipital scalp, with 10-20 collected hairs placed in a regular mailing envelope. The hair-containing envelopes will be shipped to Dr. Yu's laboratory for processing and analysis.

    Measured: Day of study conduct

  4. Confirming the presence of ectodysplasin A (EDA) gene mutations in HED subjects enrolled in this study

    Study Day 1

    Measured: Day of study conduct

Questions about this trial

What is this clinical trial studying?

An observational study of Hypohidrotic Ectodermal Dysplasia, run by Edimer Pharmaceuticals at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 Jun 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Use skin assessment techniques to characterize skin properties in male subjects affected by HED compared with healthy controls, including determination of the number of sweat ducts and the rate of sweating (time frame: Day of study conduct). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Jun 2012.
