Pharmacokinetic, Safety and Tolerability Study of Recombinant Von Willebrand Factor / Recombinant Factor VIII Complex in Type 3 Von Willebrand Disease

The objectives of this study are to evaluate the immediate tolerability and safety of rVWF:rFVIII in subjects with Type 3 Von Willebrand Disease after administration of various dosages of VWF:RCo.


Eligibility Criteria:
Inclusion Criteria:

* Subject has voluntarily given written informed consent (before conduct of any study-related procedures)

* The subject has a medical history of at least 25 exposure days to VWF/FVIII coagulation factor concentrates
* The subject has a Karnofsky score \>= 70%
* The subject is between 18 to 60 years of age (on the day of signing the informed consent)
* NOT APPLICABLE IN ITALY: Female subjects of child-bearing potential must have a negative pregnancy test and agree to practice contraception using a method of proven reliability from the day of screening until the study completion visit
* APPLICABLE ONLY IN ITALY: Female subjects of child-bearing potential must have a negative pregnancy test and agree to practice non-hormonal-based contraception using a method of proven reliability (IUD acceptable) from the day of screening until 96 hours after the last investigational drug infusion
* NOT APPLICABLE IN ITALY: The subject must agree not to be on any therapy (hormone-based contraception acceptable) interfering with coagulation factor pharmacokinetics until 96 hours after the last investigational drug infusion
* APPLICABLE ONLY IN ITALY: The subject must agree not to be on any therapy interfering with coagulation factor pharmacokinetics until 96 hours after the last investigational drug infusion

Exclusion Criteria:

* The subject has been diagnosed with a hereditary or acquired coagulation disorder other than VWD (including qualitative and quantitative platelet disorders and/or an international normalized ratio (INR) \> 1.4)
* The subject has been diagnosed with an ADAMTS13 deficiency with less than 10% ADAMTS13 activity
* The subject has a history or presence of VWF inhibitor
* The subject has a history or presence of FVIII inhibitor with a titer \>= 0.4 BU (by Nijmegen assay) or \>= 0.6 BU (by Bethesda assay)
* The subject has a known hypersensitivity to mouse or hamster proteins
* The subject has a medical history of immunological disorders, excluding seasonal allergic rhinitis/conjunctivitis, food allergies or animal allergies

* In the judgment of the investigator, the subject has another clinically significant concomitant disease (e.g. uncontrolled hypertension, diabetes type II) that may pose additional risks for the subject

* The subject is receiving or anticipates receiving another investigational and/or interventional drug within 30 days before enrollment
* The subject is a lactating female
* The subject has a history of drug or alcohol abuse within the last 5 years
* The subject has a progressive fatal disease and/or life expectancy of less than 3 months
* The subject is identified by the investigator as being unable or unwilling to cooperate with study procedures
* The subject suffers from a mental condition rendering him/her unable to understand the nature, scope and possible consequences of the study and/or evidence of an uncooperative attitude
* Subject is in prison or compulsory detention by regulatory and/or juridical order
