No Inhibitors in Previously Treated Patients (PTPs)
with Hemophilia A Treated with wilate®1

Immune system antibody response immunogenicity was assessed in a pooled analysis that selected from 136 previously treated patients (PTPs) across 5 clinical studies. 83 subjects fulfilled study criteria:

  • At least 150 exposure days at the time of enrollment in clinical study
  • Treated for at least 50 exposure days and 6 months

Development of inhibitors in the immune system can block the effectiveness of many medications. No patient developed inhibitors to wilate®.

Rate of inhibitor development was 0% (95% CI, 0-4.35%)

No Serious Systemic Adverse Drug Reactions Were Reported1

  • 136 previously treated patients (PTPs) with hemophilia A (aged 11 to 66 years) received wilate® in 5 clinical studies that involved prophylactic (preventive) use, on-demand treatment, surgery and/or pharmacokinetics (the processing of drugs within the body).
  • Subjects received over 19 million units of wilate® during 9,001 exposure days.
  • The most common adverse reaction was pyrexia (fever) (2 subjects; 1.5%). Other adverse reactions included pruritus (itchy skin), headache and sleeping disorder. The most serious adverse reactions to treatment with wilate® are hypersensitivity reactions (immune system reactions such as allergies and autoimmunity).
  • Two subjects in the pivotal study had transient (short-lived) worsening of pre-existing thrombocytosis (elevated platelet count) while on the study, that remains unexplained.

Indications and Important Safety Information for wilate® [von Willebrand Factor/Coagulation Factor VIII Complex (Human)].

Please see wilate® full Prescribing Information.

Indication

wilate® is a von Willebrand Factor/Coagulation Factor VIII Complex (Human) indicated in adult and pediatric patients with von Willebrand disease for on-demand treatment and control of bleeding episodes; for perioperative management of bleeding; and for routine prophylaxis to reduce the frequency of bleeding episodes. wilate® is also indicated in adult and pediatric patients 12 years of age and older with hemophilia A for on-demand treatment and control of bleeding episodes; and for routine prophylaxis to reduce the frequency of bleeding episodes.

Contraindications

Do not use in patients with known hypersensitivity reactions, including anaphylactic or severe systemic reaction, to human plasma-derived products, any ingredient in the formulation, or components of the container.

Warnings and Precautions

  • Anaphylaxis and severe hypersensitivity reactions are possible
  • Thromboembolic events may occur. Monitor plasma levels of FVIII activity
  • Neutralizing antibodies (inhibitors) to VWF and Factor VIII have occurred following administration of wilate®. Test for neutralizing antibodies if plasma VWF and/or Factor VIII level fail to increase as expected or if bleeding is not controlled after wilate® administration
  • wilate® is made from human plasma and carries the risk of transmitting infectious agents

Adverse Reactions

The most common adverse reactions (≥ 1%) in clinical trials on VWD were hypersensitivity reactions, urticaria, chest discomfort, and dizziness. The most common adverse reaction (≥ 1%) in clinical trials in hemophilia A was pyrexia (fever).
