Phase:
PHASE2
Brief Summary
In some patients with Duchenne muscular dystrophy (DMD), the disease is caused by a nonsense mutation (premature stop codon) in the gene that makes the dystrophin protein. PTC124 has been shown to par...
Detailed Description
In this study, patients with DMD due to a nonsense mutation will be treated with a new investigational drug called PTC124. To determine if a patient qualifies for the study evaluation procedures will ...
Eligibility Criteria
Inclusion
- Diagnosis of DMD based on a clinical phenotype presenting by age 5, with increased serum CK and decrease of dystrophin on a muscle biopsy
- Presence of a nonsense mutation in the dystrophin gene
- Physical examination or radiographic imaging documenting the presence of EDB or TA muscles in both legs
- Ability to ambulate, or if non-ambulatory, then not requiring ventilator support

Exclusion
- Prior or ongoing medical condition (e.g., concomitant illness, psychiatric condition, alcoholism, drug abuse), medical history, physical findings, ECG findings, or laboratory abnormality that, in the investigator's opinion, could adversely affect the safety of the subject, makes it unlikely that the course of treatment or follow-up would be completed, or could impair the assessment of study results
- Clinical symptoms and signs of congestive cardiac failure
- Positive hepatitis B surface antigen, hepatitis C antibody test, or human immunodeficiency virus (HIV) test
- Hemoglobin \<10 g/dL
- Serum albumin \<2.5 g/dL
- Abnormal GGT or total bilirubin (\>laboratory's upper limit of normal)
- Abnormal renal function (serum creatinine \>1.5 times laboratory's upper limit of normal)
- History of solid organ or hematological transplantation
- Ongoing immunosuppressive therapy (other than corticosteroids)
- Exposure to another investigational drug within 28 days prior to start of study treatment
- Ongoing participation in any other therapeutic clinical trial
- Ongoing use of thiazolidinedione peroxisome proliferator-activated receptor gamma (PPAR γ) agonists, e.g., rosiglitazone (Avandia® or equivalent) or pioglitazone (Actos® or equivalent)
- Change in systemic corticosteroid therapy (e.g., initiation of treatment; cessation of treatment; change in dose, schedule, or type of steroid) within 3 months prior to start of study treatment.
- Treatment with systemic aminoglycoside antibiotics within 4 weeks prior to start of study treatment
