入选标准

  • 1. Confirmed diagnosis of LGMD 2C including:
  • 1.1. Molecular analysis proving del525T mutation on ?-sarcoglycan gene (chromosome 13) at homozygous state
  • 1.2. Muscle biopsy with immunohistochemical and/or Western blot analysis showing marked decrease or absence of ?-sarcoglycan staining in muscle, as well as a fibrosis assessment should be available. If not, an initial muscular biopsy may be performed during the pre-enrolment period
  • 2. Minimum age of 15 years
  • 3. Males and females may be equally enrolled
  • 4. Adequate carpi radialis muscle bulk for muscle biopsy as assessed by examination
  • 5. Subjects should be able to communicate with the investigation staff
  • 6. Subjects should be able to understand, to comply with and to perform all needed evaluations during the trial period including muscle strength tests
  • 7. Forearm muscle strength should be of at least 3+ as assessed through the British Medical Research Council (MRC) Manual Muscle Testing (MMT) scale
  • 8. Subjects should also have already lost ambulation
  • 9. Subjects should be able and willing to return for follow up
  • 10. Subjects should be able and willing to give signed informed consent
  • 11. For minor subjects, a signed informed consent will be given by a legally authorised representative
  • 12. Eligible subjects belonging to a multiplex family should not be enrolled in the same cohort

排除标准

  • 1. Severity of disease and presence of ill-prognosis complications:
  • 1.1. Severe respiratory dysfunction such as subjects with tracheostomy or forced vital capacity (FVC) < 1000ml and/or < 30%
  • 1.2. Uncompensated heart failure
  • 1.3. An ejection fraction (EF) < 30% as measured on either echocardiography or scintigraphy
  • 1.4. Severe rhythm disturbances and/or high degree conduction defect in the absence of a pacemaker insertion
  • 2. Underlying conditions, diseases or active viral infections likely to increase risk of complications or to interfere with the investigational treatment:
  • 2.1. Contraindications for injections and muscle biopsies
  • 2.2. Platelet count < 100,000/mm3
  • 2.3. Total bilirubin > 10 mg/l (> 17 µmol/l)
  • 2.4. Serum creatinine > 110 µmol/l
  • 2.5. Lymphocytes CD4+ < 250/mm3 (< 15%)
  • 2.6. History of diabetes mellitus
  • 2.7. Current infectious diseases, including known positive human immunodeficiency virus (HIV) serology, hepatitis B and C
  • 2.8. Abnormal profile on protein immunoelectrophoresis
  • 2.9. Immunisations of any kind within the past month
  • 2.10. Receipt of another investigational agent within 4 weeks of study enrolment
  • 2.11. History of or current steroid medication for indications other than muscular dystrophy, chemotherapy, radiotherapy or other immunosuppressive therapy
  • 2.12. Steroid medication, if any, should be discontinued at least 3 months before entering the protocol and not received during the study
  • 2.13. Pregnant or lactating women
  • 2.14. Females or males of childbearing age must be willing to employ adequate contraception, that is to use condoms during the 3 months following the administration of the product
  • 2.15. Pre-injection neutralising anti-AAV1 antibodies titer (on pre-enrolment / D-30 visit) superior or equal to 1/800
