New Data to be Presented for ROCTAVIAN from Phase 3 GENEr8-1 Study, Including Data on the Impact of ROCTAVIAN on Quality of Life and Musculoskeletal Health for Adults with Severe Hemophilia A
SAN RAFAEL, Calif., June 22, 2023 /PRNewswire/ -- BioMarin Pharmaceutical Inc. (Nasdaq: BMRN), a global biotechnology company dedicated to transforming lives through genetic discovery, today announced it will present new data from the ROCTAVIAN™ (valoctocogene roxaparvovec) gene therapy clinical trial program. These data will be shared this week in four oral presentations and two posters at the 31st Congress of the International Society on Thrombosis and Haemostasis (ISTH) in Montreal, Canada.
The U.S. Food and Drug Administration (FDA) has set a PDUFA Target Action Date of June 30, 2023, for the Company's Biologics License Application (BLA) for valoctocogene roxaparvovec gene therapy. The European Commission (EC) granted conditional marketing authorization under the brand name ROCTAVIAN on August 24, 2022.
"With our ROCTAVIAN clinical program, we are embarking on a new era in the treatment of people with severe hemophilia A," said Hank Fuchs, M.D., president of Worldwide Research and Development at BioMarin. "These data presented at ISTH will highlight the clinical impact of ROCTAVIAN for people living with severe hemophilia A more than three years post-infusion."
New data from the ongoing, global Phase 3 GENEr8-1 study – the largest to date for any hemophilia gene therapy – will highlight the impact of ROCTAVIAN on hemostatic efficacy, durability and quality of life of individuals with severe hemophilia A more than three years after infusion. Additional presentations will further explore the impact of ROCTAVIAN on the health and life experiences of people with hemophilia A after two years in the GENEr8-1 study using a tool called PROBE (Patient Reported Outcomes, Burdens and Experiences) and assess the impact of ROCTAVIAN on musculoskeletal health in people with severe hemophilia A.
Key ROCTAVIAN presentations at ISTH include:

Robust Clinical Program
BioMarin has multiple clinical studies underway in its comprehensive gene therapy program for the treatment of severe hemophilia A. In addition to the global Phase 1/2 and Phase 3 GENEr8-1 studies, the company is also conducting a single arm, open-label study to evaluate the efficacy and safety of ROCTAVIAN at a dose of 6e13 vg/kg with prophylactic corticosteroids in people with severe hemophilia A (Study 270-303). There is also an ongoing study with the 6e13 vg/kg dose of ROCTAVIAN in people with severe hemophilia A with pre-existing AAV5 antibodies (Study 270-203) and a study with the 6e13 vg/kg dose of ROCTAVIAN in people with severe hemophilia A with active or prior Factor VIII (FVIII) inhibitors (Study 270-205).
About Hemophilia A
Hemophilia A, also called FVIII deficiency or classic hemophilia, is an X-linked genetic disorder caused by missing or defective FVIII, 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.
People living with hemophilia A lack sufficient functioning FVIII 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% of the hemophilia A population. People with hemophilia A with moderate (FVIII levels 1-5%) or mild (FVIII levels 5-40%) disease show a much-reduced propensity to bleed. Individuals with severe hemophilia A are treated with a prophylactic regimen of intravenous FVIII infusions administered 2-3 times per week (100-150 infusions per year) or a bispecific monoclonal antibody that mimics the activity of FVIII administered 1-4 times per month (12-48 injections or shots 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.
