- Type 3 ( Von Willebrand factor antigen (VWF:Ag) ≤ 3 IU/dL) or,
- Severe Von Willebrand disease (VWD) with a history of requiring substitution therapy with von Willebrand factor concentrate to control bleeding
- Participant, who participates in the treatment for bleeding episodes, has had a minimum of 1 documented bleed (medical history) requiring VWF coagulation factor replacement therapy during the previous 12 months prior to enrollment.
- Participant has a Karnofsky score ≥ 60%
- Participant is at least 18 and not older than 65 years of age at enrollment
- If female of childbearing potential, participant presents with a negative pregnancy test

- Participant is willing and able to comply with the requirements of the protocol
Exclusion

- Participant has a documented history of a VWF:RCo half-life of \<6 hours.
- Participant has a history or presence of a VWF inhibitor at screening.
- Participant has a history or presence of a factor VIII (FVIII) inhibitor with a titer ≥0.4 BU (by Nijmegen assay) or ≥ 0.6 BU (by Bethesda assay).

- Participant has been diagnosed with renal disease, with a serum creatinine level ≥2 mg/dL.
- In the judgment of the investigator, the participant has another clinically significant concomitant disease (eg, uncontrolled hypertension) that may pose additional risks for the participant.
- Participant has been treated with an immunomodulatory drug, excluding topical treatment (eg, ointments, nasal sprays), within 30 days prior to enrollment
- Participant is pregnant or lactating at the time of enrollment.
- Participant has participated in another clinical study involving an IP or investigational device within 30 days prior to enrollment or is scheduled to participate in another clinical study involving an investigational product or investigational device during the course of this study.
- Participant has a history of drug or alcohol abuse within the 2 years prior to enrollment.
- Participant has a progressive fatal disease and/or life expectancy of less than 3 months.
- Participant is identified by the investigator as being unable or unwilling to cooperate with study procedures.
- Participant 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.
