powder in a bottle for dissolution in water for oral administration
Experimental: Cohort 2
AT2220 high dose, regimen 1, for 11 weeks

Detailed Description:

Subjects meeting all eligibility criteria will undergo physical examination, electrocardiogram (ECG), spirometry, muscular strength test, functional muscle test, 6-minute walk test (6MWT) (when appropriate), laboratory tests, MRI and muscle (needle) biopsy. Quality of life will be assessed via SF-36 questionnaire. Functional ability and level of handicap will be assessed by Rotterdam handicap scale.

  5. Functional grade for arms and/or legs ≥2 OR sitting FVC ≥30% and <80% of predicted value, reproducible between visits 1 and 2 (± 15%)
  6. Subjects of reproductive potential agree to use reliable methods of contraception during the study
  7. Subject or legal representative is willing and able to provide written informed consent

Exclusion Criteria:

  1. Any intercurrent condition that may preclude accurate interpretation of study data
  2. Obstructive pulmonary disease
  3. Invasive ventilatory support
  4. Use of noninvasive ventilatory support >8 hours/day while awake
  5. History of QTc prolongation >450 msec for males and >470 msec for females
  6. History of allergy or sensitivity to the study drug, including any prior serious adverse reaction to iminosugars (e.g., miglustat, miglitol)
  7. Pregnancy or breast-feeding
  8. Current or recent drug or alcohol abuse
  9. Treatment with another investigational drug within 30 days of study start
  10. Use of prohibited medications ≤3 months prior to screening
  11. Otherwise unsuitable for the study in the opinion of investigator
