  5. History of incremental recovery of Factor VIII <1.35% per IU/kg infused

  13. Liver disease (alanine aminotransferase [ALT], aspartate aminotransferase [ AST] > 3x the ULN)
  14. History of diabetes or other metabolic disease
  15. History of hypersensitivity or serious adverse reaction to recombinant or plasma-derived FVIII concentrate

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
ACTIVE_COMPARATOR: PK substudy
A cohort of 13-18 subjects will be included in the pharmacokinetic (PK) evaluation of GreenGene™ F and an approved recombinant Factor VIII product (Refacto AF); a minimum of 13 of these subjects will be re-evaluated at study end (50 exposure day).

Other Names:
  • GreenGeneF
  • GreenGene F
EXPERIMENTAL: Prophylaxis safety and efficacy substudy
Hemostatic efficacy of GreenGene™ F will be assessed by its effectiveness in controlling spontaneous or traumatic bleeding episodes and by the rate of breakthrough bleeding during prophylaxis over ≥ 50 exposure days.
intra-venous infusion, 30 ± 5 IU/kg infusions 3 times per week with dose escalation to 45 ± 5 IU/kg if appropriate, for 50 exposure days
Other Names:
