Experimental Drug Being Tested in Mitochondrial and Metabolic Disorders, FA

Update (Feb. 13, 2013):In February 2013, study coordinator Lynne Wolfe at the National Institutes of Health said the NIH study of EPI-743 in metabolic and mitochondrial disordersis seeking children with undiagnosed, suspected disorders of energy metabolism. Children who have a gentically confirmed metabolic or mitochondrial disorder will not be accepted into this study.

Edison Pharmaceuticals has announced it is conducting a clinical trial of its experimental drug EPI-743 in children with the mitochondrial myopathyLeigh syndrome, and is planning a trial of this compound in Friedreich's ataxia (FA).

EPI-743 is a small-molecule, oral drug that is designed to enter the central nervous system and synchronize (improve) energy generation in mitochondria, the energy-producing subunits in cells. It is being developed by Edison, which is located in Mountain View, Calif., and Utrecht, Netherlands.

The U.S. National Institutes of Health (NIH) also is testing this molecule in a broader range of disorders, including all metabolic diseases of muscle and mitochondrial myopathies.

Edison's Leigh syndrome trial now open

The Leigh syndrome trial is expected to enroll 30 children ages 1 to 12 at four U.S. sites. The sites are in Palo Alto, Calif.; Akron, Ohio; Houston, Texas; and Seattle, Washington.

Prospective participants must:

  • have a confirmed genetic mutation associated with Leigh syndrome;
  • show moderate disease severity, with documented evidence of disease progression within the previous year;
  • must not take coenzyme Q10, vitamins C or E, lipoic acid or idebenone; and
  • meet other study criteria.

FA trial planned, access program closed

Edison also is planning a trial to test the effect of EPI-743 on visual function in people with FA. Study sites are likely to include the University of South Florida in Tampa, Children's Hospital of Philadelphia, and the University of California, Los Angeles.

More information on this trial will be reported as it becomes available.

An earlier Edison study, which allowed access to EPI-743 for patients with a mitochondrial myopathy or FA who were judged to be within 90 days of end-of-life care, is now closed to new participants.

NIH trial opens in metabolic, mitochondrial disorders

The U.S. National Institutes of Health (NIH) in Bethesda, Md., is conducting a trial of approximately 20 children ages 2 to 11 who have a metabolic disease of muscle or a mitochondrial myopathy.

Metabolic muscle diseases in MDA's program include:

Mitochondrial myopathies in MDA's program include:

Prospective participants must:

  • have clinical findings of a neuromuscular disease with impaired energy production (typical symptoms include poor muscle tone, abnormal muscle tone or seizures);
  • have a disorder that is untreatable or poorly treatable;
  • be willing to abstain from initiating dietary supplements or nonprescribed medications and from specially fortified foods or beverages; and
  • meet other study criteria.

For details, see EPI-743 for Metabolism or Mitochondrial Disorders; or enter NCT01642056 in the search box at ClinicalTrials.gov.

About Clinical Trials

About Clinical Trials

A clinical trial is a test, in humans, of an experimental treatment. Although it's possible that benefit may be derived from participating in a clinical trial, it's also possible that no benefit, or even harm, may occur.

MDA has no ability to influence who is chosen to participate in a clinical trial.
