入选标准

  • 1. Adults males, = 18 years of age;
  • 2. Confirmed diagnosis of HB defined as one of the following: Documented severe FIX deficiency with plasma FIX activity of <1% of normal or moderately severe FIX deficiency with plasma FIX activity level between =1% and =2% and a severe bleeding phenotype defined by one of the following:
  • (a) On prophylaxis for a history of bleeding, or
  • (b) On demand therapy with a history of 4 or more bleeding episodes/year on average over the past 3 years, or
  • (c) Evidence of chronic haemophilic arthropathy (pain, joint destruction, and loss of range of motion).
  • 3. Able to give full informed consent and able to comply with all requirements of the trial including 15-year long-term follow-up;
  • 4. Willing to practice barrier contraception until at least three consecutive semen samples after vector administration are negative for vector sequences;
  • 5. Lack of neutralising anti-AAV-S3 antibodies using an in-vivo transduction inhibition assay within 4 weeks of vector administration.
  • 6. At least 150 exposure days to FIX concentrates.
  • 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 16
  • F.1.3 Elderly (>=65 years) yes
  • F.1.3.1 Number of subjects for this age range 8

排除标准

  • 1. Presence of neutralising anti-human FIX antibodies (inhibitor, determined by the Bethesda inhibitor assay) at the time of enrolment or a previous history of FIX inhibitor;
  • 2. Patients at high risk of thromboembolic events (high risk patients would include those with a history of arterial or venous thromboembolism (e.g. deep vein thrombosis, pulmonary embolism, non-haemorrhagic stroke, arterial embolus) and those with acquired thrombophilia including conditions such as atrial fibrilation).
  • 3. Use of investigational therapy for haemophilia within 30 days before enrolment;
  • 4. Patients with active hepatitis B or C, and HBsAg or HCV RNA viral load positivity, respectively, or currently on antiviral therapy for hepatitis B or C. (Negative viral assays in 2 samples, collected at least 5 months apart, will be required to be considered negative. Both natural clearers and those who have cleared HCV on antiviral therapy are eligible.);
  • 5. Serological evidence of HIV-1;
  • 6. Evidence of liver dysfunction (persistently elevated alanine aminotransferase, aspartate aminotransferase, bilirubin >1.5 x upper limit of normal).
  • 7. Platelet count <50x109/L;
  • 8. Uncontrolled glaucoma, diabetes mellitus, or hypertension;
  • 9. Malignancy requiring treatment;
  • 10. Patients with uncontrolled cardiac failure, unstable angina or myocardial infarction in the past 6 months.
  • 11. Poor performance status (World Health Organization score >1);
  • 12. Prior treatment with any gene transfer medicinal product;
  • 13. Known or suspected intolerance, hypersensitivity or contrainidication to the investigational product and non-investigational medicinal products or their excipients;
  • 14.Planned major elective surgery prior to the end of trial.
  • 15. Current or relevant history of a physical or psychiatric illness or any medical condition that in the opinion of the investigator could affect the patients safety or interfere with the study assessments.
  • 16. CMV IgG positive patients who are CMV PCR positive at screening.
