  • b) Moderately-severe (=1% - =2% FVIII activity) receiving FVIII prophylaxis
  • 3. Greater than 150 exposure days to treatment with FVIII products
  • 4. Fertile males (not surgically sterilized) who have sexual partners that are women of childbearing potential must be willing to use a barrier method of contraception (e.g. condoms) for at least 90 days post-SIG-001 administration
  • 5. Normal levels of von Willebrand factor (VWF) antigen (=50 IU/dL)
  • 6. Able and willing to provide informed consent
  • 7. Willing to withdraw from FVIII prophylaxis during specified periods in the study
  • 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 2

排除标准

  • 1. Morbid obesity defined as body mass index (BMI) =35
  • 2. Current FVIII inhibitors (>0.6 NBU/mL) or prior Immune Tolerance Induction (ITI)
  • Note: Patients with a history of low and/or transient inhibitors require Sponsor review and approval.
  • 3. History of allergic reaction or anaphylaxis to recombinant FVIII products, alginate (including seaweed and algae), or barium and barium products (including barium contrast agents)
  • 4. Evidence of any bleeding disorder in addition to haemophilia A
  • 5. Abnormal laboratory values, as follows:
  • a) Platelet count <100 × 109/L
  • b) Creatinine =1.5 mg/dL
  • c) Haemoglobin <11 g/dL
  • d) Elevated levels (i.e. greater than 2 × upper limit of normal (ULN) of aspartate aminotransferase (AST), alanine aminotransferase (ALT), or total bilirubin
  • Note: Patients with a known history of Gilbert’s disease and bilirubin levels above ULN are not excluded.
  • 6. Active infection with Hepatitis B or Hepatitis C virus, defined as a positive HBsAg, HBeAg, HBV DNA, or HCV RNA results, or currently managed with antiviral medications for Hepatitis B or C
  • 7. Uncontrolled HIV infection, defined as CD4+ counts =200/µL or by a viral load of >200 copies/mL
  • 8. Active alcoholism or drug addiction during the 12 months before the screening visit
  • 9. Active malignancy or history of malignancy in the 5 years prior to study entry, exclusive of surgically removed non-melanoma skin cancer
  • 10. Participation in another investigational medicine or device study within 90 days of screening or 5 investigational product half-lives, whichever is longer
  • 11. Prior administration of a gene therapy product
  • 12. Treatment with emicizumab less than 6 months prior to screening.
  • Note: Patients with emicizumab exposure may be eligible before 6 months of prior exposure if FVIII activity assessed by one stage assay is back to pre-emicizumab treatment levels.
  • 13. Unable to tolerate general anaesthesia required for the laparoscopic procedure
  • 14. History of:
  • a) Abdominal adhesions due to prior large, median laparotomy(ies)
  • Note: Uncomplicated prior laparoscopic procedures are not exclusionary (e.g. cholecystectomy, laparoscopic appendectomy or diagnostic laparoscopy).
  • b) Septic peritonitis
  • c) Intraperitoneal mesh
  • d) Inflammatory Bowel Disease (IBD), including ulcerative colitis or Crohn’s disease
  • 15. Other comorbidities that in the opinion of the Investigator increase the risk of abdominal adhesions
  • 16. Any disease or medical condition that in the Investigator’s opinion is a contraindication for anaesthesia or the laparoscopic procedure (e.g. prior significant cardiovascular events)
  • 17. In the Investigator’s judgment, the patient is unlikely to complete all protocol-required study visits, procedures, or comply with the study requirements for participation
