Clinical Trial Summary

This is a multicenter, longitudinal, prospective observational natural history study of subjects with a molecularly confirmed diagnosis of CMT4J. The study will enroll 20 subjects of any age into a uniform protocol for follow-up and evaluations. Subject visits will occur every 12 months + 4 weeks for up to 2 years.


Description:

This is a multicenter, longitudinal, prospective observational natural history study of subjects with a molecularly confirmed diagnosis of CMT4J. The study will enroll 20 subjects of any age into a uniform protocol for follow-up and evaluations. The study will obtain demographic and medical history information. Natural history data will be collected prospectively on an annual basis and may include physical/neurological exams, standard laboratory tests, CMT outcome and disability measures, neuropsychological tests, nerve conduction studies (NCS), and imaging studies (muscle MRI). Pulmonary function test (PFT) and scoliosis series x-ray Subject visits will occur every 12 months + 4 weeks for up to 2 years. Subjects who terminate from the study prior to Visit 3 will undergo an early termination/end of study visit (EOS) if possible. The early termination/end of study visit is comprised of the Visit 3 assessments. If needed, the Investigator may conduct unscheduled visits with Sponsor's approval. No investigational product will be used during the study.

Eligibility Inclusion Criteria: 1. Male or female, all ages 2. A molecularly-confirmed diagnosis of CMT4J (confirmed by a CLIA certified, CE-marked, or equivalent lab): Genomic DNA mutation analysis demonstrating 1) bi-allelic pathogenic and/or likely pathogenic variants (by ACMG criteria) in the FIG4 gene, or 2) bi-allelic variants with one pathogenic and/or likely pathogenic variant in trans with a variant of uncertain significance if laboratory evidence and expert consensus exits in support of loss of FIG4 function exists. 3. Informed consent from patients 18 years or older who are able to provide consent and from caregivers; parent(s)/guardian(s) providing consent for subjects younger than 18 years at Screening and patients older than 18 years unable to provide informed consent 4.

Able and willing to comply with the study protocol, including travel to Study Center, procedures, measurements and visits Exclusion Criteria: 1. Any known genetic abnormality, including chromosomal aberrations that confound the clinical phenotype 2. Current participation in an interventional or therapeutic study 3. Receiving an investigational drug within 90 days of the Baseline Visit 4. Prior or current treatment with gene or stem cell therapy 5. Any other diseases which may significantly interfere with the assessment of CMT4J 6. Have any other conditions, which, in the opinion of the Investigator or Sponsor would make the subject unsuitable for inclusion or could interfere with the subject participating in or completing the study
