E.4 | Principal exclusion criteria |
1.

Any uncontrolled medical or neurological/neurodegenerative condition (other than Friedreich ataxia). 3. Clinically significant psychiatric illness (e.g., uncontrolled major depression, schizophrenia, bipolar affective disorder) within 6 months prior to screening. 4. Patients with significant clinical dysphagia. 5. Hypersensitivity to nicotinamide. 6. Patients known to be positive for human immunodeficiency virus (HIV). 7. Patients with a significant history of substance abuse (e.g. alcohol or drug abuse) within the previous six months before enrolment. 8. Patients with a history of severe allergies to medications. 9. Indication of impaired liver function as shown by an abnormal liver function profile at screening (e.g., repeated values of aspartate aminotransferase [AST], alanine aminotransferase [ALT] and bilirubin ≥3 × the upper limit of normal). 10. History of malignancy or carcinoma. The following exceptions may be made after discussion with the Sponsor: • Subjects with cancers in remission more than 5 years prior to screening. • Subjects with a history of excised or treated basal cell or squamous carcinoma. • Subjects with prostate cancer in situ. 11. History or evidence of an autoimmune disorder considered clinically significant by the Investigator or requiring chronic use of systemic corticosteroids or other immunosuppressants. 12. History of clinically significant cardiac disease (ejection fraction < 40% (normal range 50-70%), cardiac insufficiency defined as New York Heart Association (NYHA) Class >2; clinically significant congenital or acquired valvular disease; symptomatic coronary disease such as prior myocardial infarction or angina, B-type natriuretic peptide (BNP) level increase more than 2 x of the normal age- and gender dependent range; history of unstable arrhythmias, history of atrial fibrillation). 13. The subject received an investigational drug within 30 days prior to inclusion into this study. 14. Patients taking sodium valproate or any other known histone deacetylase inhibitor. 15. Use of vitamin B1 (thiamine), withdrawal should be at least 3 months prior Screening. 16. Use of vitamin B3 (nicotinamide), withdrawal should be at least 3 months prior Screening. 17. If patients are taking idebenone or coenzyme Q10 (CoQ), this should be stable over the last three months and not changed during the study. 18. The subject is unwilling or unable to provide written informed consent and to follow the procedures outlined in the protocol. 19. For subjects who will undergo an MRI: Any contraindications to MRI such as, but not limited to cardiac pacemaker, implanted cardiac defibrillator, aneurysm clips, carotid artery vascular clamp, neurostimulator, implanted drug infusion devices, metal fragments or foreign objects in the eyes, skin or body, bone growth/fusion stimulator, cochlear, otologic implant, severe claustrophobia or any condition that would counterindicate an MRI scan. 20. Patients participating in another interventional clinical trial, excluding natural history/observational studies, at start of the study or within the last 30 days before study start. 21. The subject is mentally or legally incapacitated. 22. Pregnant females as determined by positive [serum or urine] hCG test at Screening or prior to dosing. Participants of child-bearing age should use adequate contraception as defined in the study protocol. 23. Lactating females.
