  • Muscle Function [ Time Frame: 8 weeks ]
  • Muscle Stength [ Time Frame: 8 weeks ]
Efficacy Primary Endpoint: Evaluation of (-)-epicatechin on blood and muscle tissue markers of mitochondrial biogenesis and muscle regeneration in adults with Becker muscular dystrophy. [ Time Frame: 8 weeks ]
Treatment with 8 weeks of (-)- epicatechin 100mg daily will induce mitochondrial biogenesis, muscle regeneration, and improved histological appearance in sarcomere morphology.

-(-)Epicatechin Pharmacokinetics [ Time Frame: 8 Weeks ]
Standard clinical safety panel including: hematologic, hepatologic, renal and metabolic profiles
  • Efficacy Secondary Endpoints: Evaluation of the effects of (-)-epicatechin on exercise capacity in adults with Becker muscular dystrophy. [ Time Frame: 8 Weeks ]
    Individuals with Becker muscular dystrophy who receive 100mg/day of (-)-epicatechin will demonstrate improved exercise performance and strength that is associated with increases in mitochondrial biogenesis and muscle regeneration.
  • Safety Secondary Endpoints: Evaluation of safety and pharmacokinetic profiles of (-)-epicatechin in adults with Becker muscular dystrophy. [ Time Frame: 8 Weeks ]
    Assessments of safety will include a standard clinical safety panel including hematologic, hepatologic, renal and metabolic profiles. Pharmacokinetic studies will include repeat assessments of trough, 2 hour-post (peak) and 4-hour post dose (-)-epicatechin levels.
Normalization of Muscle Stucture [ Time Frame: 8 weeks ]
Evaluation by histology, Western Blot, immunostain and electron microscopy
Pilot Biomarker Endpoints: Pilot evaluation of disease- and epicatechin-specific circulating mRNA and miRNA blood profiles as pilot biomarkers for monitoring treatment efficacy. [ Time Frame: 8 weeks ]
Epicatechin stimulates follistatin expression in tissue and blood. In addition to its effects on muscle regeneration, follistatin is known to exert anti-inflammatory and anti-fibrotic effects via antagonism of activin and myostatin.
 
Use of (-)-Epicatechin in the Treatment of Becker Muscular Dystrophy (Pilot Study)
An Open-label Pilot Study of Purified Tea-derived Epicatechin to Improve Mitochondrial Function, Strength and Skeletal Muscle Exercise Response in Becker Muscular Dystrophy.
(-)-Epicatechin will be evaluated for the treatment of progressive muscle loss and impaired skeletal muscle function in Becker Muscular Dystrophy (BMD) patients.

This is a proof-of-concept phase 1/2a pilot and endpoint development study that is designed to provide initial evidence of biological activity of (-)-epicatechin. Primary endpoints include initial assessment of tissue-specific evidence of efficacy from muscle biopsy samples. Secondary endpoints include measures of strength and physical function, and safety and adverse event data. Pilot endpoints include assessment of mRNA and miRNA peripheral blood profiles and validation of non-invasive near-infrared spectroscopy (NIRS) muscle perfusion studies during exercise and a recumbent cycle exercise test that may be employed as endpoints in future clinical trials.

This single center open-label pilot study will enroll 10 adults with genetically-confirmed Becker muscular dystrophy, who will receive the purified nutritional extract (-)-epicatechin 100mg/day orally for 8 weeks. After screening visits, participants will be enrolled in the study if they meet all inclusion criteria. They will be evaluated at baseline and at screening, day 1, and weeks 1, 2, 4 and 8.

Inclusion Criteria:

  • Male
  • Age 18 years to 60 years
  • Average to low daily physical activity
  • Ability to ambulate for 75 meters without assistive devices
  • Diagnosis of BMD confirmed by at least one the following:

    • Dystrophin immunofluorescence and/or immunoblot showing partial dystrophin deficiency, and clinical picture consistent with typical BMD, or
    • Gene deletions test positive (missing one or more exons) of the dystrophin gene, where reading frame can be predicted as 'in-frame', and clinical picture consistent with typical BMD, or
    • Complete dystrophin gene sequencing showing an alteration (point mutation, duplication, or other mutation resulting in a stop codon mutation) that can be definitely associated with BMD, with a typical clinical picture of BMD, or
    • Positive family history of BMD confirmed by one of the criteria listed above in a sibling or maternal uncle, and clinical picture typical of BMD.
