About this trial
This is an interventional treatment trial for Limb-Girdle Muscular Dystrophy, Type 2E focused on measuring limb girdle muscular dystrophy, LGMD2E, beta-sarcoglycan, gene transfer, adeno-associated virus, LGMDR4
Eligibility Criteria
INCLUSION CRITERIA
- Males or females of any ethnic group
- β-SG deoxyribonucleic acid (DNA) gene mutations at both alleles
- Weakness demonstrated based on history of difficulty in running, jumping and climbing stairs
- A 100 meter walk/run (MWR) test result: ≥40 % of predicted for age-, height-, gender-, and weight-matched healthy controls at the screening visit
EXCLUSION CRITERIA
- Active viral infection based on clinical observations
- Cardiac magnetic resonance imaging (MRI) determined left ventricular ejection fraction (LVEF) <40%
- Serological evidence of human immunodeficiency virus (HIV), hepatitis B, or hepatitis C infection
- Diagnosis of (or ongoing treatment for) an autoimmune disease
- Abnormal laboratory values considered clinically significant
- Concomitant illness or requirement for chronic drug treatment that, in the opinion of the Principal Investigator, creates unnecessary risks for gene transfer.
Other inclusion/exclusion criteria apply.
