Octapharma USA announced on August 13, 2015 that the U.S. Food and Drug Administration (FDA) has approved revised product labeling for WILATE庐 [von Willebrand Factor/Coagulation Factor VIII Complex (Human)] to include 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庐, 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.

鈥淧reventing excessive intra- and post-operative bleeding in pediatric and adult VWD patients is a continuing challenge,鈥 said Octapharma USA President Flemming Nielsen. 鈥淲e are extremely pleased that WILATE庐 is now available for medical providers managing this important issue. Octapharma is committed to providing life saving and enhancing therapeutic options for the bleeding disorders community.鈥

The overall efficacy rate of WILATE庐 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庐 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.1


WILATE庐 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庐, specifically a solvent/detergent (S/D) and terminal dry-heat (TDH) treatment.

锟硷考锟硷考锟硷考锟硷考锟硷考锟硷考锟硷考锟硷考WILATE庐 is a von Willebrand Factor/Coagulation Factor VIII Complex (Human) indicated for the on-demand treatment and control of bleeding episodes. WILATE庐 is also indicated for the perioperative management of bleeding. WILATE庐 is not indicated for the treatment of hemophilia A.

Important Safety Information

WILATE庐 is contraindicated for patients who have known hypersensitivity reactions, including anaphylactic or severe systemic reaction, to human plasma-derived products, any ingredient in the formulation, or components of the container. Thromboembolic events have been reported in VWD patients receiving coagulation factor replacement therapies. FVIII activity should be monitored to avoid sustained excessive FVIII levels. Development of neutralizing antibodies to FVIII and to VWF, especially in VWD Type 3 patients, may occur. WILATE庐 is made from human plasma. The risk of infectious agents, including viruses and, theoretically, the Creutzfeldt-Jacob disease agent, cannot be completely eliminated. The most common adverse reactions to treatment with WILATE庐 in patients with VWD were hypersensitivity reactions, urticaria, and dizziness. Seroconversions for antibodies to parvovirus B19 not accompanied by clinical signs of disease have been observed. The most serious adverse reactions to treatment with WILATE庐 in patients with VWD were hypersensitivity reactions.
