To determine the pk profile after single administration of two doses of BAY 79-4980 (high and low: 35 IU FVIII/Kg reconstituted in 22 mg and 13 mg of liposomes/kg, respectively) compared to rFVIII-FS (35 IU/Kg reconstituted in 2.5 mL WFI/1000 IU) in PTPs [ Time Frame: 6 weeks ] [ Designated as safety issue: Yes ]

  • To determine the infusion tolerability of both BAY 79-4980 doses, by evaluation of vital signs and adverse events [ Time Frame: 6 weeks ] [ Designated as safety issue: Yes ]
  • To determine the safety of both BAY 79-4980 doses by measuring the effects on laboratory parameters - especially the lipid profile and adverse events [ Time Frame: 6 weeks ] [ Designated as safety issue: Yes ]
  • To determine the pk characteristics of liposomes - esp body clearance by measuring the major liposome component 1-palmitoyl-2-oleoyl-sn-glycerol-3-phosphocholine (POPC) and the non-biological liposome component, MPEG 2000 DSPE, as surrogate marker [ Time Frame: 6 weeks ] [ Designated as safety issue: Yes ]
  • To determine the activity of rFVIII over time (as determined by thrombin generation assay and the rotation thromboelastography [RoTEG] assay) for both doses of BAY 79-4980 compared to rFVIII-FS [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • Additional analyses of the number and timing of spontaneous bleeds after each study treatment will be assessed [ Time Frame: 6 weeks ] [ Designated as safety issue: Yes ]

Pharmacokinetics and Safety of a Single Intravenous Infusion of BAY 79-4980
A Randomized, Double-blind, Cross-over Study to Determine the Pharmacokinetics and Safety of a Single Intravenous Infusion of BAY 79-4980 in Previously Treated Patients With Severe Hemophilia A

The primary objective of this study is to determine the pharmacokinetic profile after single administration of two doses of BAY 79-4980 (high and low: 35 IU FVIII/Kg reconstituted in 22 mg and 13 mg of liposomes/Kg, respectively) compared to rFVIII-FS (35 IU/Kg reconstituted in 2.5 mL WFI/1000 IU) in PTPs aged 12 to 60 years with severe hemophilia A.

Inclusion Criteria:

  • Males aged 12 to 60 years
  • Hemophilia A with plasma FVIII level less than 1% (severe hemophilia)
  • No history of FVIII inhibitor antibody formation and no current evidence of inhibitor antibody measured using the Nijmegen modified Bethesda assay (< 0.6 Nijmegen Bethesda Units [N.B.U.]/mL)
  • No signs or symptoms of an acute bleeding episode on the day of infusion
  • Four or more days without treatment with FVIII prior to the day of infusion
  • Subject (or the subject's legal representative) must provide written informed consent and authorization of use and disclosure of Protected Health Information (PHI)
  • Subjects must have been previously treated with FVIII concentrate for a total of at least 200 exposure days, including 20 exposure days in the previous 12 months. Previous treatment can have been with any type of rFVIII or plasma-derived FVIII concentrate

Exclusion Criteria:

  • Individuals with abnormal renal function (serum creatinine concentrations greater than 1.3 mg/dL) or active hepatic disease (persistent aspartate aminotransferase [AST] or alanine aminotransferase [ALT] increases to greater than five times the upper limit of normal).
  • Individuals with anemia, as defined by hemoglobin level less than 12 g/dL
  • Any individual with a past history of severe reaction(s) to FVIII products
  • Any individual on interferon treatment or who has received interferon within the previous 3 months
  • Any individual with thrombocytopenia (platelets greater than or equal to 100,000 cells/mm3) or known hematologic/bleeding problems other than hemophilia A

  • Any individual who requires pre-medication for FVIII infusions (e.g., antihistamines)
  • Any individual with high blood pressure (defined as diastolic blood pressure great than or equal to 100 mm/Hg)
  • Any patient who cannot forego FVIII treatment for at least 4 days prior to study entry or between study infusions due to a need for more frequent prophylactic treatment because of a pre-existing medical condition
  • Any patient with known allergy or severe reactions to liposomes or PEG
