Commitment to Advancing Care for People with Hemophilia A Demonstrated with Largest and Longest, Ongoing Clinical Development Program for any Gene Therapy in Hemophilia A
European Commission Approval for Valoctocogene Roxaparvovec Expected Q3 2022
SAN RAFAEL, Calif., July 11, 2022 /PRNewswire/ -- BioMarin Pharmaceutical Inc. (NASDAQ: BMRN) today announced that it presented four oral presentations and two poster presentations on valoctocogene roxaparvovec, an investigational gene therapy for the treatment of adults with severe hemophilia A, at the International Society on Thrombosis and Haemostasis (ISTH) 2022 World Congress from July 9-12 in London.
"With each passing year, the breadth of data supporting valoctocogene roxaparvovec increasingly demonstrate the positive impact gene therapy treatment may provide people with severe hemophilia A. These presentations at ISTH offer supportive evidence of long-term hemostatic efficacy, consistent safety results in clinical studies, efficacy from our pivotal study that is consistent with propensity scoring, the clearance of the vector, and on health-related quality of life over six years," said Hank Fuchs, M.D., President of Worldwide Research and Development at BioMarin. "We look forward to an anticipated approval of valoctocogene roxaparvovec in Europe and providing a therapy that could represent an important and valuable treatment choice for patients with severe Hemophilia A by offering the potential to reduce both the burden of the disease as well as the burden of treatment."
"BioMarin continues to increase and share important data about investigational valoctocogene roxaparvovec that may be useful for patients and physicians to evaluate therapeutic options based on an individual's unique circumstances," said one of the presenters Professor Johnny Mahlangu, a study investigator and Professor in Haematology and Head of School of Pathology in the Faculty of Health Sciences of the University of the Witwatersrand in Johannesburg, South Africa.
Presentation of these data at ISTH follows the Committee for Medicinal Products for Human Use (CHMP) adopting a positive opinion recommending conditional marketing authorization (CMA) for valoctocogene roxaparvovec for adults with severe hemophilia A. Valoctocogene roxaparvovec is the first gene therapy to be recommended for approval in Europe for hemophilia A. A final approval decision, typically consistent with the CHMP recommendation, is expected from the European Commission in Q3 2022.

About Hemophilia A
People living with hemophilia A lack sufficient functioning Factor VIII protein to help their blood clot and are at risk for painful and/or potentially life-threatening bleeds from even modest injuries. Additionally, people with the most severe form of hemophilia A (FVIII levels <1%) often experience painful, spontaneous bleeds into their muscles or joints. Individuals with the most severe form of hemophilia A make up approximately 50 percent of the hemophilia A population. People with hemophilia A with moderate (FVIII 1-5%) or mild (FVIII 5-40%) disease show a much-reduced propensity to bleed. The standard of care for individuals with severe hemophilia A is a prophylactic regimen of replacement Factor VIII infusions administered intravenously up to two to three times per week or 100 to 150 infusions per year. Despite these regimens, many people continue to experience breakthrough bleeds, resulting in progressive and debilitating joint damage, which can have a major impact on their quality of life.
Hemophilia A, also called Factor VIII deficiency or classic hemophilia, is an X-linked genetic disorder caused by missing or defective Factor VIII, a clotting protein. Although it is passed down from parents to children, about 1/3 of cases are caused by a spontaneous mutation, a new mutation that was not inherited. Approximately 1 in 10,000 people have Hemophilia A.
