What is Wilate?

Wilate is an injection medication containing antihemophilic and von Willebrand factors is used for prevention of excessive bleeding during and after minor and major surgery in adult and pediatric von Willebrand disease (VWD) patients. VWD is a complex congenital bleeding disorder that affects one to two percent of the general population or approximately 3 million people in the United States.

The newly approved product label expands the FDA license for WILATE, which formerly included only the treatment of spontaneous and trauma-induced bleeding episodes in patients with severe VWD, as well as patients with mild or moderate VWD in whom the use of desmopressin is known or suspected to be ineffective or contraindicated. Octapharma USA is a subsidiary of global human protein products manufacturer Octapharma AG, which develops and manufactures high-purity coagulation factor concentrates for patients with bleeding disorders.

“Preventing excessive intra- and post-operative bleeding in pediatric and adult VWD patients is a continuing challenge,” said Octapharma USA President Flemming Nielsen. “We are extremely pleased that WILATE is now available for medical providers managing this important issue. Octapharma is committed to providing lifesaving and enhancing therapeutic options for the bleeding disorders community.”

The overall efficacy rate of WILATE treatment for surgical procedures was 96.7% in a global, prospective, open-label, single-arm, uncontrolled, multi-center Phase III clinical study, which included nine U.S. hemophilia treatment centers. The clinical trial observed 28 patients with Type 1, Type 2 and Type 3 VWD from 24 centers in eight countries who underwent 30 surgeries and 280 infusions. WILATE treatment was successful in 100% of minor surgeries and 95.2% of major surgeries. The study reported a 100% success rate in surgical procedures for Type 3 patients, the most serious form of VWD.

Also its better to know that WILATE is a plasma-derived, highly purified concentrate of freeze-dried human von Willebrand factor (VWF) and coagulation factor VIII (FVIII). Two well-established virus inactivation steps are incorporated into the manufacturing process of WILATE specifically a solvent/detergent (S/D) and terminal dry-heat (TDH) treatment.

WILATE is also indicated for the perioperative management of bleeding. WILATE is not indicated for the treatment of hemophilia A.
