Clinical trials and research studies are vitally important to improving health and quality of life for people with Duchenne muscular dystrophy. Clinical trials are research studies in humans designed to study if an experimental therapy or treatment works. The importance of this research must be balanced with the need for each family to carefully decide if trial participation is right for them.

Open Label Extension

Open Label Extension Trials typically follow a placebo trial, where all participants are now on drug and can be monitored for an additional period of time. Participating in a previous trial may be a requirement for being enrolled in an Open Label Extension.

  • Combatting Fibrosis – Reducing the amount of scar tissue development that leads to muscle breakdown.
  • Improving Heart Function – Strategies aiming to protect and improve cardiac muscle in Duchenne
  • Improving Muscle Growth and Protection – Enhancing muscle growth while minimizing muscle breakdown
  • Observational – Studies that aim to strengthen our understanding of the disease, these are studies that do not typically include an investigational product such as a drug.
  • Reducing Inflammation – Lessening the chronic inflammation that is an effect of muscle degradation in Duchenne
  • Regulating Calcium Balance – Control the flow of calcium in and out of the muscle that is disrupted by the damaged muscle cells
  • Restoring or Replacing Dystrophin – Strategies that seek to address the absence of dystrophin protein in muscle.
  • Restoring the Cells Energy – Promoting healthy mitochondria cells which can enhance muscle cell functions such as muscle repair
  • Robotics – Utilization of devices to improve quality of life and assistance with activities of daily living.
