入选标准
- •1. Adult males, = 18 years of age with classic Fabry disease.
- •2. Confirmed diagnosis of classic Fabry disease (including historical documentation of a classic pathological GLA mutation).
- •3. Plasma and/or leucocyte alpha galactosidase activity at screening (measured by central laboratory activity assay at trough) less than 5% of normal according to the central laboratory reference ranges.
- •4. One or more of the characteristic features of classic Fabry disease: neuropathic pain, corneal verticillata, clustered skin angiokeratoma.
- •5. Plasma LysoGb3 levels > 83ng/ml at screening (Part 2 only)
- •6. Estimated glomerular filtration rate (eGFR) =60mL/min/1.73m2.
- •7. <1gm/24 hours of urinary protein, determined by urine spot analysis and 24-hour urine analysis (required if urine spot analysis >500mg of urinary protein) at screening.
- •8. Able to give full informed consent and able to comply with all requirements of the trial including 5-year long-term follow-up.
- •9. Willing to practice barrier contraception until at least 2 consecutive semen samples (as specified in the study schedule of assessments) after vector administration are negative for vector sequences.
- •10. Lack of neutralising anti-AAVS3 antibodies using an in vitro transduction inhibition assay within 6 weeks prior to vector administration.
- •Are the trial subjects under 18? no
- •Number of subjects for this age range:
- •F.1.2 Adults (18-64 years) yes
- •F.1.2.1 Number of subjects for this age range 10
- •F.1.3 Elderly (>=65 years) yes
- •F.1.3.1 Number of subjects for this age range 2
排除标准
- •1. Presence of either R118C, A143T, or other GLA mutations leading to non-classical Fabry disease manifestation and any mutations that have not yet been classified.
- •2. Presence of antibodies to aGLA, Replagal, or Fabrazyme as defined by a positive result in the screening assay.
- •3. Patients with chronic kidney disease, stages 3-5 Kidney Disease: Improving Global Outcomes (KDIGO 2012 classification).
- •4. Patients with severe myocardial fibrosis (=3 segments) identified by magnetic resonance imaging (MRI).
- •5. Use of investigational therapy for Fabry disease within 60 days before enrolment.
- •6. Evidence of liver dysfunction (persistently elevated ALT, aspartate aminotransferase (AST), bilirubin >1.5 x upper limit of normal).
- •7. Platelet count < 50 x 109/L.
- •8. Patients receiving warfarin or other anticoagulants interfering with the ability to perform renal or skin biopsies, or patients with a clinically significant bleeding disorder.
- •9. Either history of, or a positive serology test at screening for hepatitis B surface antigen (HBsAg), hepatitis C antibody (HCAb), or human immunodeficiency virus (HIV).
- •10. Uncontrolled glaucoma, diabetes mellitus, or hypertension.
- •11. Malignancy requiring treatment.
- •12. Patients with uncontrolled cardiac failure, unstable angina, or myocardial infarction in the past 6 months.
- •13. Prior treatment with any gene transfer medicinal product.
- •14. Known or suspected intolerance, hypersensitivity or contraindication to the investigational medicinal product (IMP) and non-investigational medicinal products (NIMPs) or their excipients.
- •15. Patients who are assessed as having any contraindications to MRI. Including patients with ferromagnetic metallic implants, including pacing and defibrillator devices, nerve stimulators and cochlear implants.
- •16. Patients who have had a renal transplant.
