Becker Muscular Dystrophy - A Natural History Study to Predict Efficacy of Exon Skipping

This study is ongoing, but not recruiting participants.

Cooperative International Neuromuscular Research Group Identifier:
First received: February 22, 2012
Last updated: January 23, 2017
Last verified: January 2017
This is a multi-center natural history study that will be conducted at participating centers in the Cooperative International Neuromuscular Research Group (CINRG). Following a baseline evaluation, participants will have three follow-up visits over a three-year period. The investigators will characterize the Becker muscular dystrophy phenotype, and correlate specific abnormal dystrophin proteins with the range of clinical outcomes.

Primary Outcome Measures:
  • Strength and function [ Time Frame: Annual ]
  • Quality of life [ Time Frame: Annual ]

    These questionnaires include:

    • Pediatric Quality of Life Inventory (PedsQL)
    • Pediatrics and Adult Neuromuscular module Quality of Life (NeuroQOL)

  • Medical history assessment - ambulation status, medication history, hospitalizations, surgeries, nutrition, fractures, and cardiac tests [ Time Frame: Annual ]

Enrollment: 85
Study Start Date: April 2012
Estimated Study Completion Date: March 2017
Estimated Primary Completion Date: March 2017 (Final data collection date for primary outcome measure)

BMD participants over 4 years of age with in-frame deletions in the dystrophin gene.

Detailed Description:
We will utilize the Cooperative International Neuromuscular Research group (CINRG) network to collect cohorts of Becker muscular dystrophy (BMD) patients with in-frame deletions in the dystrophin gene. We will collect clinical data across multiple body systems and correlate these findings to the high-resolution deletion break-point mapping performed from the tissue samples. We will investigate the observed variability to deepen our understanding of molecular mechanisms relevant to the optimization of exon skipping therapeutic approaches.

Ages Eligible for Study:   4 Years and older   (Child, Adult, Senior)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
BMD participants over 4 years of age with in-frame deletions in the dystrophin gene.

Inclusion Criteria:

  • Age 4 or older
  • Diagnosis of BMD with an in-frame deletion in the dystrophin gene, where the boundaries of the mutations are confirmed.

Exclusion Criteria:

• Investigator assessment of inability to comply with protocol
