Exclusion criteria
Exclusion criteria: 1. Age of onset of disease =25 years 2. Left ventricular ejection fraction (LVEF) 480 msec in 3 consecutive ECG recordings taken at least 5 minutes apart. 4. Known intolerance to pioglitazone or other thiazolidinediones. 5. Subjects who are taking or have taken pioglitazone, or other thiazolidinediones, within the past 6 months prior to Screening. 6. Currently participating in or having participated in another interventional clinical study within 2 months prior to Screening. 7. Requiring other prohibited concomitant medication (see Table 4). Note: use of idebenone, coenzyme Q10, antioxidants, riboflavin, thiamine, vitamins C and E is permitted provided the dose has been constant for =3 months before Screening and is kept constant during the entire study. 8. Previous or current history of vesical polyps, bladder cell hyperplasia, or bladder cancer. 9. Previous or current history of other cancer, unless surgically resected and without evidence of recurrence for a minimum of 5 years. 10. Clinically significant anemia (i.e. hemoglobin below 110 g/L). 11. Glycated hemoglobin (HbA1c) levels >6.4% and fasting blood glucose levels = 0.9 times the lower limit of normal and = 1.1 times the upper limit of normal. 12. NT-proB-type natriuretic peptide level (NTproBNP) >125 pg/mL 13. Abnormal liver enzyme tests for aspartate aminotransferase or alanine aminotransferase of >2 times the upper limit of normal or total bilirubin >1.5 times the upper limit of normal (unless due to Gilbert’s syndrome). 14. A positive result on laboratory tests for hepatitis B surface antigen, hepatitis C antibody and human immunodeficiency virus antibody at screening. 15. Moderate or severe hepatic impairment (groups B and C according to the revised Child-Pugh classification; (Pugh, Murray-Lyon et al. 1973). 16. Chronic kidney disease (CKD) stages 3a or higher (according to CKD staging by Renal Association with an estimated glomerular filtration rate of <60 ml/min/1.73m2). 17. Contraindications for MRS/MRI procedure such as subjects with ferromagnetic materials in the body, such as dental braces, spinal rods, aneurysm clips, pacemakers, intraocular metal or cochlear implants. 18. Drug or alcohol abuse in the past 2 years by subject history and/or investigator assessment. 19. Conditions which could modify the absorption of the study drug, such as inflammatory bowel diseases, or stomach or intestinal resection. 20. Inability or unwillingness of the subject or subjects’ parents/caregivers to comply with the study procedures. 21. Other medical, neurological, psychiatric, or social conditions that in the investigator’s opinion are likely to confound the assessment of safety or efficacy, interfere with study conduct, or unfavorably alter the risk-benefit of subject participation. 22. Pregnant women as confirmed by a positive blood pregnancy test. 23. Female patients intending to breast feed a child while taking study drug or have taken study drug within 30 days after administration of the last dose.

Optional assessment (explorat objective) -Various biochemical parameters in plasma, & CSF. Optional assessment. (explorat objective) -Safety & tolerability of MIN-102 ;Primary end point(s): Change from baseline in spinal cord area cervical segment C2-C3 [mm2] ;Timepoint(s) of evaluation of this end point: Baseline, week 24 and week 48 | — |
