Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Participants will receive an initial dose of VONVENDI of 40 to 80 international units per kilogram (IU/kg) of body weight. If a participant's baseline factor VIII (FVIII) level is not high enough to help stop bleeding, VONVENDI will be given along with 30 to 45 IU/kg of ADVATE rFVIII.
Participants will be in the study for approximately 14 months. During the study, participants will be followed up at clinics or over telephone calls.

Study Groups

All Participants With VWD
Participants will receive a single intravenous (IV) dose of VONVENDI at baseline PK assessment. During the 12-month on-demand (OD) treatment period, any bleeding episodes requiring replacement therapy with VWF will be treated with VONVENDI with or without ADVATE. Participants may also receive VONVENDI with or without ADVATE intravenous infusions, when indicated deemed necessary for perioperative bleeding management \[major, minor and oral surgery\]. Participants will receive initial dose of VONVENDI of 40 to 80 IU/kg of body weight.
VONVENDI
VONVENDI is administered by intravenous injection.
ADVATE
ADVATE is administered by intravenous injection.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Participant has a documented diagnosis of severe VWD (baseline VWF:RCo less than \[\<\]20 international units \[IU\]deciliter \[dL\]) with a diagnosis of VWD type verified per the following recommended criteria:
* Type 1 (von Willebrand factor:Ristocetin cofactor activity \[VWF:RCo\] \<20 IU/dL and by VWF activity/VWF:antigen \[Ag\] ratio) or,
* Type 2A or type 2B (by VWF activity/VWF:Ag ratio and multimer pattern, with genetics if necessary), type 2N (FVIII:C \<10% and genetics), type 2M (by VWF activity/VWF:Ag ratio and multimer pattern) or
* Type 3 (VWF:Ag \<=3 IU/dL). Diagnosis is confirmed, when applicable, by genetic testing and/or by multimer analysis.
3. Participant is at least 18 years of age at screening.
4. Participant is ethnic Chinese and lives in China, including those from Taiwan, Hong Kong, and Macao.
5. If female of childbearing potential, participant presents with a negative pregnancy test and agrees to employ adequate birth control measures for the duration of the study.
6. Participant is willing and able to comply with the requirements of the protocol.
7. Participant has had a minimum of 3 documented bleeds that indicated the need for VWF coagulation factor replacement therapies during the previous 12 months prior to enrollment.
Exclusion Criteria
2. Participant has a history or presence of a VWF inhibitor at screening.
3. Participant has a documented history of a VWF:RCo half-life of \<6 hours.
4. Participant has a history or presence of a FVIII inhibitor with a titer greater than or equal to \[\>=\] 0.6 Bethesda units per milliliter \[BU/mL\] (by Bethesda assay or Bethesda method with Nijmegen modification).
5. Participant has a known hypersensitivity to any of the components of the study drugs, such as to mouse or hamster proteins.
6. Participant has a medical history of immunological disorders, excluding seasonal allergic rhinitis/conjunctivitis, mild asthma, food allergies or animal allergies.
7. Participant has a medical history of a thromboembolic event.
8. Participant is human immunodeficiency virus (HIV) positive with an absolute cluster of differentiation 4 (CD4) count \<200/cubic millimeter (mm\^3).
9. Participant has been treated with an immunomodulatory drug, other than antiretroviral chemotherapy eg, α-interferon, or corticosteroid agents at a dose equivalent to hydrocortisone greater than 10 milligram (mg)/day (excluding topical treatment \[eg, ointments, nasal sprays\]), within 30 days prior to signing the informed consent (or assent, if appropriate).
10. Participant is pregnant or lactating at the time informed consent is obtained.
11. 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 IP or investigational device during the course of this study.
12. Participant is diagnosed with progressive fatal disease and/or has a life expectancy of less than 15 months.
13. Participant is member of the study team conducting this study or in a dependent relationship with one of the study team members. Dependent relationships include close relatives (that is, children, partner/spouse, siblings, parents) as well as employees.
14. Participant has an acute illness (eg, influenza, flu-like syndrome, allergic rhinitis/conjunctivitis, nonseasonal asthma) at screening.
15. Participant is diagnosed with significant liver disease, as evidenced by, but not limited to, any of the following: serum alanine aminotransferase (ALT) greater than 5 times the upper limit of normal; hypoalbuminemia; portal vein hypertension (eg, presence of otherwise unexplained splenomegaly, history of esophageal varices) or liver cirrhosis classified as Child-Pugh class B or C.
16. Participant has been diagnosed with renal disease, with a serum creatinine level \>=2.5 milligram per deciliter (mg/dL).
17. Participant has a platelet count \<100,000/ milliliter (mL) at screening (except for participants with type 2B VWD, whose platelet count\[s\] at screening will be evaluated taking into consideration historical trends in platelet counts and the investigator's medical assessment of the participant's condition).
18. Participant has cervical or uterine conditions causing menorrhagia or metrorrhagia (including infection, dysplasia).
19. In the judgment of the investigator, the participant has another clinically significant concomitant condition (eg, uncontrolled hypertension) that may pose additional risks for the participant.
20. Participant is identified by the investigator as being unable or unwilling to cooperate with study procedures.
