9. Abstention from use of all pill-form dietary supplements and non-prescribed medications (except as allowed by the investigator)

10. Abstention from foods or beverages or bars fortified with Coenzyme Q10, vitamin E, super-fortified "functional" foods or beverages

11. Abstention from use of idebenone

12. Clinically staged with a Mitochondrial Disease Scale such as the Newcastle Score

Exclusion criteria:

1. Allergy to EPI-743, vitamin E or sesame oil

2. Clinical history of bleeding or abnormal prothrombin time (PT)/partial thromboplastin time (PTT) (excluding anticoagulation Rx)

3. Hepatic insufficiency with liver function tests (LFTs) greater than two times normal

4. Renal insufficiency requiring dialysis

5. Fat malabsorption syndromes precluding drug absorption

6. Any other concurrent inborn errors of metabolism
