Study Endpoints

Primary Endpoints

Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)
Up to 14 months

A TEAE is defined as an adverse event with an onset that occurs after receiving study drug. An SAE is any untoward medical occurrence that at any dose: results in death, life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent, significant disability/incapacity, a congenital abnormality/birth defect, an important medical event in the opinion of the healthcare provider, may jeopardize the participant or may require intervention to prevent one of the other outcomes listed in the definition above. TEAEs consist of both serious and non-serious adverse events.

Number of Participants With TEAEs by Severity
Up to 14 months

Number of participants with severity of TEAE will be reported.

Number of Participants With TEAEs and SAEs by Causality
Up to 14 months

Number of participants with causality related TEAEs and SAEs will be reported.

Number of Participants With Thromboembolic Events and Severe Hypersensitivity Reactions
Up to 14 months

Number of participants with thromboembolic events and severe hypersensitivity reactions will be reported.

Number of Participants Who Develop Neutralizing (Inhibitory) Antibodies to VWF and FVIII
Up to 14 months

Number of participants who develop neutralizing antibodies to VWF and FVIII will be reported.

Number of Participants Who Develop Binding Antibodies to VWF and FVIII
Up to 14 months

Number of participants who develop total binding antibodies to VWF and FVIII will be reported.

Number of Participants With Clinically Significant Abnormalities in Laboratory Parameters
Up to 14 months

Number of participants with clinically significant abnormalities from baseline values in laboratory parameters per investigator assessment will be reported.

Number of Participants With Clinically Significant Abnormalities in 12-lead Electrocardiogram (ECG)
Up to 14 months

Number of participants with clinically significant abnormalities from baseline values in ECG per investigator assessment will be reported.

Number of Participants With Clinically Significant Abnormalities in Vital Signs Parameters

Number of participants with clinically significant abnormalities from baseline values in vital sign parameters per investigator assessment will be reported.

Annualized Bleeding Rate (ABR) for Spontaneous or Traumatic Bleeding Episodes as Assessed by Investigator During Prophylactic Treatment With Vonicog Alfa (rVWF)
12 months

ABR during the study compared to historical ABR for each participant for both spontaneous and traumatic bleeding episodes as classified by the investigator during prophylactic treatment with vonicog alfa (rVWF) will be reported.

Spontaneous Annualized Bleeding Rate (sABR)
Up to 12 months

sABR was derived as \[number of treated bleeds\] / \[duration in years\]. Bleeds with unknown causality were considered as spontaneous. Bleeds were categorized based on the investigator assessment of cause. sABR during the first 12 months of prophylactic treatment with rVWF (vonicog alfa) was reported.

Hemostatic Efficacy
Within 24 hours after the last infusion of study drug following the onset of the bleeding episode (if/when the severity and/or duration of the bleeding requires the infusion of the study drug)

Treatment success for vonicog alfa-treated nonsurgical bleeding episodes (using a 4-point scale: Excellent, Good, Moderate, None).

Secondary Endpoints

Number of Infusions of VONVENDI With or Without ADVATE per Bleeding Episode
Up to 12 months
Number of Infusions of ADVATE per Bleeding Episode
Up to 12 months
Weight-adjusted Consumption of VONVENDI and ADVATE per Bleeding Episode
Up to 12 months

Treatment Arms

ArmTypeDescription
All Participants With VWDEXPERIMENTALParticipants 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.
Cohort 1: Participants With Age >=12 to <18 yearsEXPERIMENTALParticipants 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).
Cohort 2: Participants With Age >=6 to <12 yearsEXPERIMENTALParticipants with age \>=6 to \<12 years who have received OD therapy of VWF product or prophylactic treatment with a pdVWF product will receive vonicog alfa (rVWF) with an initial dose selected within the range of 40 to 60 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).
Cohort 3: Participants With Age <6 yearsEXPERIMENTALParticipants with age \<6 years who have received OD therapy of VWF product or prophylactic treatment with a pdVWF product will receive vonicog alfa (rVWF) with an initial dose selected within the range of 40 to 60 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).
On-DemandEXPERIMENTALParticipants will receive recombinant von Willebrand factor (rVWF) (with or without ADVATE).
ProphylaxisEXPERIMENTALParticipants will receive recombinant von Willebrand factor (rVWF).
On-demand TreatmentEXPERIMENTALParticipants will receive vonicog alfa (recombinant von Willebrand factor \[rVWF\]) treatment for non-surgical bleeding episodes over a 12 to 18-month period.
Elective SurgeryEXPERIMENTAL12-24 hours prior to surgery and within 3 hours of surgery. Minor surgery: infuse every 12-24 hours for at least 48 hours based on post-operative dosing. Oral Surgery: infuse at least once within first 8-12 hours post-surgery based on post-operative dosing. Major Surgery: infuse every 12-24 hours for at least first 96 hours post-surgery based on post-operative dosing.
Emergency SurgeryEXPERIMENTALWithin 3 hours prior to surgery. Minor surgery: infuse every 12-24 hours for at least 48 hours based on post-operative dosing. Oral Surgery: infuse at least once within first 8-12 hours post-surgery based on post-operative dosing. Major Surgery: infuse every 12-24 hours for at least first 96 hours post-surgery based on post-operative dosing.

Frequently asked questions about Vonvendi

What is Vonvendi used for?

Vonvendi is used to treat von Willebrand disease, a bleeding disorder caused by a deficiency or defect in von Willebrand factor. It is a recombinant von Willebrand factor therapy given to control and prevent bleeding episodes in patients with this condition.

Who makes Vonvendi?

Vonvendi is developed by Takeda Pharmaceutical Company Limited, which trades under the ticker TAK. Takeda is the company responsible for the clinical development program for this recombinant von Willebrand factor product.

What phase is Vonvendi in?

Vonvendi is in Phase 3 clinical development. Three trials are listed for the program, with two currently recruiting and one completed. The completed trial enrolled 47 participants, and the two active studies together plan to enroll 44 more.

What clinical trials is Vonvendi in?

Vonvendi is being studied in NCT07129343, a Phase 3 trial in Chinese participants with von Willebrand disease that is recruiting 20 patients, and NCT05582993, a Phase 3 trial in children with severe von Willebrand disease recruiting 24 patients across the United States, France, Ireland, Italy, Japan, and the United Kingdom. A completed Phase 3 trial, NCT02932618, studied recombinant von Willebrand factor with or without ADVATE in 47 children.

Is Vonvendi the same as vonicog alfa?

Yes, Vonvendi is the brand name for vonicog alfa, also written as vonicog alfa. People searching for either name are looking at the same recombinant von Willebrand factor product developed by Takeda for von Willebrand disease.
