WHIPPANY, N.J., Dec. 17, 2014 /PRNewswire/ -- Bayer HealthCare has submitted a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) seeking approval for BAY 81-8973, a recombinant Factor VIII (rFVIII) compound, for the treatment of hemophilia A in children and adults. The submission was based on results from the LEOPOLD (Long-Term Efficacy Open-Label Program in Severe Hemophilia A Disease) clinical trials, which evaluated BAY 81-8973 in adults and children using two- and three-times-per-week prophylaxis dosing regimens.

About Hemophilia A
"The LEOPOLD study program and the submission of BAY 81-8973 are a demonstration of Bayer's continued, longstanding commitment to the hemophilia A community," said Dario Mirski, M.D., Vice President and Head, U.S. Medical Affairs, Bayer HealthCare Pharmaceuticals.
BAY 81-8973 is an investigational agent and is not approved by the United States Food and Drug Administration (FDA), the European Medicines Agency (EMA) or other health authorities. An application for marketing authorization for BAY 81-8973 was submitted to the EMA in December 2014 for approval of the same indication in the European Union.
About LEOPOLD The LEOPOLD (Long-Term Efficacy Open-Label Program in Severe Hemophilia A Disease) Clinical Development Program consists of three multinational clinical trials designed to evaluate the pharmacokinetics, efficacy, and safety of BAY 81-8973 in subjects with severe hemophilia A (<1% FVIII:C).
LEOPOLD I is an open-label, randomized study. Part A studied the pharmacokinetics of BAY 81-8973. Part B evaluated the safety, tolerability and efficacy of prophylaxis with BAY 81-8973. Part C evaluated hemostatic outcome during major surgery. Included were male patients (ages 12-65 years) with severe hemophilia A (<1% FVIII:C). The primary endpoint of Part B was annualized number of all bleeds over 12 months.
LEOPOLD II is a randomized, cross-over, open-label trial also in male subjects aged 12 to 65 years. In this Phase II/III study, 80 subjects were randomized to receive BAY 81-8973 either as a low-dose prophylaxis regimen (20-30 IU/kg; n=28) twice-per-week, high-dose prophylaxis (30-40 IU/kg; n=31) three-times-per-week, or on-demand (n=21). The primary objective was to demonstrate the superiority of prophylaxis versus on-demand therapy, with the primary endpoint being bleeding frequency at 12 months.
LEOPOLD Kids is a two-part, open-label, non-randomized phase III study. Part A is designed to evaluate the efficacy and safety of BAY81-8973 for prophylaxis, treatment of bleeds, and surgical management in previously treated children <=12 years of age. Part B of the study, which involves previously untreated patients (PUPs), is ongoing.
About Hemophilia A Hemophilia A, also known as factor VIII deficiency or classic hemophilia, is a largely inherited bleeding disorder in which one of the proteins needed to form blood clots in the body is missing or reduced. Hemophilia A is the most common type of hemophilia and is characterized by prolonged or spontaneous bleeding, especially into the joints, muscles or internal organs.
