Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main aim of the study is to evaluate the effectiveness of prophylaxis with vonicog alfa (recombinant von Willebrand factor \[rVWF\]) in children. This study will enroll those participants who have been previously treated with VWF product or with a plasma-derived VWF (pdVWF) product. In this study, participants will be treated with vonicog alfa (rVWF) for 12 months.

During the study, participants will visit the study clinic 5 times after treatment initiation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cohort 1: Participants With Age >=12 to <18 years

Participants with age greater than or equal to (\>=) 12 to less than (\<) 18 years who have received on-demand (OD) therapy or prophylactic treatment with a pdVWF product will receive vonicog alfa (rVWF) with an initial dose selected within the range of 40 to 60 international units per kilogram (IU/kg) vonicog alfa (rVWF), intravenous infusions, twice-weekly for 12 months. Participants may receive vonicog alfa (rVWF) with or without ADVATE intravenous infusions, when indicated (as deemed necessary for breakthrough bleeding episode treatment and perioperative bleeding management).

Group Type EXPERIMENTAL

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Exclusion Criteria

1. The participant has been diagnosed with pseudo VWD or another hereditary or acquired coagulation disorder other than VWD (example, qualitative and quantitative platelet disorders or elevated prothrombin time/international normalized ratio 1.4).
2. The participant has a history or presence of a VWF inhibitor at screening.
3. The participant has a history or presence of an factor VIII (FVIII) inhibitor with a titer \>=0.6 Bethesda units per milliliter (/mL).
4. The participant has a known hypersensitivity to any of the components of the study drugs, such as mouse or hamster proteins.
5. The participant has a medical history of immunological disorders, excluding seasonal allergic rhinitis/conjunctivitis, mild asthma, food allergies, or animal allergies.
6. The participant has a medical history of a thromboembolic event.
7. The participant is human immunodeficiency virus (HIV)-positive with an absolute helper T cell (CD4) count \<200 per cubic millimeter or microliter (/mm\^3).
8. The participant has been diagnosed with significant liver disease per the investigator's medical assessment of the participant's current condition or medical history or as evidenced by, but not limited to, any of the following: serum alanine aminotransferase (ALT) greater than 5 times the upper limit of normal (ULN), hypoalbuminemia, portal vein hypertension (example, presence of otherwise unexplained splenomegaly, history of esophageal varices), or liver cirrhosis classified as Child-Pugh class B or C.
9. The participant has been diagnosed with renal disease, with a serum creatinine level \>=2.5 milligram per deciliter (mg/dL).
10. The participant has a platelet count \<100,000/mL at screening (because participants with type 2B VWD are considered eligible for this study, for participants with type 2B VWD, platelet count\[s\] at screening will be evaluated in consultation with the sponsor, taking into consideration historical trends in platelet counts and the investigator's medical assessment of the participants condition).
11. The participant has been treated with an immunomodulatory drug, excluding topical treatment (example, ointments, nasal sprays), within 30 days prior to signing the informed consent (or assent, if appropriate).
12. The participant is pregnant or lactating at the time of enrollment.
13. The participant has cervical or uterine conditions causing menorrhagia or metrorrhagia (including infection, dysplasia).
14. The participant has participated in another clinical study involving another 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.
15. The participant has not received OD or prophylactic treatment with a VWF product prior to this study.
16. The participant has a progressive fatal disease and/or life expectancy of less than 15 months.
17. The participant is unable to complete screening procedures and/or comply with the requirements of the protocol in the opinion of the investigator, based on the joint prescreening evaluation held between the investigator and the sponsor.
18. The participant has 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.
19. The participant is member of the study team or in a dependent relationship with one of the study team members, which includes close relatives (that is, children, partner/spouse, siblings, and parents) as well as employees.
