Charcot-Marie-Tooth Disease (CMT) Infant Scale (INC-6611)

November 29, 2016 updated by: Joshua Burns, Sydney Children's Hospitals Network

Development of the Charcot-Marie-Tooth Disease Infant Scale (CMTInfS) for Infants With CMT

The purpose of this study is to develop and validate a clinical outcome measure to evaluate disability and disease progression of children 3 years of age and younger (infants and toddlers) with various types of Charcot-Marie-Tooth disease (CMT).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Most forms of CMT begin in childhood and progress throughout a person's lifetime. Current research suggests that treatment to slow disease progression may be most effective if introduced early in a patient's life before muscle weakness and sensation loss develop, as it may be easier to slow disease progression than to reverse disability that is already in place. Clinical outcome measures have been developed for adults (CMT Neuropathy Score) and for children 3 years of age and older (CMT Pediatric Scale). However, no CMT-specific clinical outcome measure currently exists to measure disease severity or progression in children from birth to 3 years of age. It is the goal of this study to develop and validate the CMT Infant Scale (CMTInfS) to meet this need.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

No older than 4 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients who are 4 years of age and under who are also enrolled in the 6601 study and have performed all tasks to complete the CMTInfant Scale will be recruited for participation. Participation entails allow the information collected in the 6601 study be used for validation in the current study.

Description

Inclusion Criteria (patients with CMT):

  • Patient is ≤4 years of age
  • Parent(s) or guardians have agreed for the child to take part in the study and have signed an informed consent form.
  • Patient has known or probable inherited neuropathy
  • Patient participates in the INC Natural History Study (INC 6601)

Inclusion Criteria (controls):

  • Participant is ≤4 years of age
  • Parent(s) or guardians have agreed for the child to take part in the study and have signed an informed consent form.
  • Participant does NOT have an inherited neuropathy as determined by the investigator
  • Participant is an unaffected friend or family member of a patient with CMT (patient does not have to be included in the study)

Exclusion Criteria (patients with CMT):

  • Patient has a known condition of acquired neuropathy including toxic (e.g. medication related), metabolic (e.g. diabetic), immune mediated or inflammatory (AIDP or CIDP) neuropathies, a neuropathy related to leukodystrophy, or a congenital muscular dystrophy.
  • Patient has a severe general medical condition, as determined by the site Principal Investigator.
  • Patient has known normal nerve conductions of upper and lower limbs. This will be considered as exclusion criteria because it documents that the child does not have a large-fibre neuropathy. However, patients will not be required to have nerve conduction studies (NCS) or electromyography (EMG).

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Patients with CMT
Two groups of patients will be included: Group 1 (Definitive): Children with known CMT where genetic testing confirms the diagnosis, or children with a clinical diagnosis including electrophysiology confirming the presence of CMT and a corresponding family history where a first or second degree relative has a genetic diagnosis; or Group 2 (At risk): A clinical diagnosis of CMT awaiting genetic testing or confirmatory electrophysiology and evidence of a genetic diagnosis in a first or second degree relative; or individuals identified as being at risk of a CMT diagnosis (prodromal patients), without the onset of signs or symptoms.
Other: No intervention involved
Controls
Healthy controls will be included from unaffected family members or friends accompanying patients at INC sites. Healthy controls are defined as boys and girls aged 0-≤4 years without a diagnosis of CMT or any of the other study exclusion criteria.
Other: No intervention involved

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
CMT Infant Scale Part 1
Time Frame: 1 year
The CMT Infant Scale physical assessment
1 year
The CMT Infant Scale Part 2
Time Frame: 1 year
The CMT Infant Scale lower limb and gross motor items
1 year
The CMT Infant Scale Part 3
Time Frame: 1 year
The CMT Infant Scale upper limb and fine motor items
1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description

Evaluate CMT Infant Scale (CMTInfS) in CMT natural history study
Time Frame: 6 months - 1 year
The sections of the CMT Infant Scale which are found to be clinically/functionally useful after one year of analysis will be carried forward for all infant patients every 6 months to one year.
