Current prophylactic therapies for hemophilia A cannot maintain Factor VIII levels for sustained periods, leading to the need for frequent, regular infusions or injections while still having a risk of ongoing, unpredictable bleeds and unavoidable, irreversible joint damage even with standard of care treatment,&#8221; said <span class=\"xn-person\">Hank Fuchs<\/span>, M.D., President of Worldwide Research and Development at BioMarin. &#8220;These data build upon the foundation for a potential transformative treatment option that addresses the root cause of severe hemophilia A.\u00a0 Later at ISTH, we look forward to sharing five years of clinical data from the ongoing Phase 1\/2 study with the longest duration of clinical experience, which complements this pivotal Phase 3 study, the largest study of a gene therapy in hemophilia A.&#8221;<\/p>\n<p>\n        <b>Valoctocogene Roxaparvovec Safety<\/b>\n      <\/p>\n<p>Overall, in the Phase 3 study, valoctocogene roxaparvovec has been well\u00a0tolerated by the 134\u00a0participants who received a single 6e13 vg\/kg dose. No participants withdrew due to adverse events.\u00a0 No participants developed inhibitors to Factor VIII, or experienced thromboembolic events.\u00a0 One participant was lost to follow-up. \u00a0Infusion reactions were defined as any AEs occurring within 48 hours post-infusion.\u00a0 The most common infusion reactions were nausea (14.2%), fatigue (7.5%), and headache (6.0%).\u00a0 Systemic hypersensitivity during or following infusion was mitigated by slowing or pausing infusion and treating with supportive medications, as indicated. \u00a0All four (3.0%) participants with an interruption due to infusion-related symptoms were able to complete their infusion.\u00a0 Twenty-two (16.4%) participants experienced a total of 43 serious adverse events (SAEs), and all SAEs resolved.\u00a0 <\/p>\n<p>Common, steroid-related side effects can occur with temporary use of corticosteroid (or alternative immunosuppressants) to manage ALT elevation. \u00a0ALT elevation was the most common AE.\u00a0 Overall, 79% of participants received corticosteroids per protocol as treatment for ALT elevation.\u00a0 The average duration of corticosteroid treatment was 33 weeks.\u00a0 Overall, 72% of participants who used any corticosteroids\u00a0reported AEs attributed to their use, most commonly acne, insomnia, cushingoid changes, and weight increased.\u00a0 Three participants reported SAEs attributed to corticosteroids.\u00a0 Other immunosuppressants were used by 29% of participants for ALT elevation due to contraindication, side effects, or poor or no response to corticosteroid treatment.\u00a0 No Grade 4 ALT elevations occurred, and no participants met Hy&#8217;s law criteria for drug-induced liver injury. <\/p>\n<p>\n        <b>GENEr8-1 Study Description<\/b>\n      <\/p>\n<p>The global Phase 3 GENEr8-1 study evaluates superiority of valoctocogene roxaparvovec at the 6e13 vg\/kg dose compared to FVIII prophylactic therapy.\u00a0 All study participants had severe hemophilia A at baseline, defined as less than or equal to 1 IU\/dL of Factor VIII activity.\u00a0 The study included 134 total participants, all of whom had a minimum of 12 months of follow-up at the time of the data cut. \u00a0The first 22 participants were directly enrolled into the Phase 3 study, 17 of whom were HIV-negative and dosed at least 2 years prior to the data cut date (referred to as the subset).\u00a0 The remaining 112 participants (rollover population) completed at least six months in a separate non-interventional study to prospectively assess bleeding episodes, Factor VIII use, and health-related quality of life while receiving Factor VIII prophylaxis prior to rolling over to receive a single infusion of valoctocogene roxaparvovec in the GENEr8-1 study.<\/p>\n<p>\n        <b>Regulatory Status<\/b>\n      <\/p>\n<p>The European Medicines Agency (EMA) validated BioMarin&#8217;s resubmission of a Marketing Authorization Application (MAA) on <span class=\"xn-chron\">July 15<\/span>, 2021.\u00a0 In <span class=\"xn-chron\">May 2021<\/span>, the EMA granted the Company&#8217;s request for accelerated assessment.\u00a0 Accelerated assessment potentially reduces the time frame for the EMA Committee for Medicinal Products for Human Use (CHMP) and Committee for Advanced Therapies (CAT) to review a MAA for an Advanced Therapy Medicinal Product (ATMP), although an application initially designated for accelerated assessment can revert to the standard procedure during the review for a variety of reasons.\u00a0The decision to grant accelerated assessment has no impact on the eventual CHMP and CAT opinion on whether a marketing authorization should be granted.\u00a0 A CHMP and CAT opinion is anticipated in the first half of 2022.\u00a0 <\/p>\n<p>The MAA submission includes safety and efficacy data from the 134 subjects enrolled in the Phase 3 GENEr8-1 study, all of whom have been followed for at least one year after treatment with valoctocogene roxaparvovec, as well as four and three years of follow-up from the 6e13 vg\/kg and 4e13 vg\/kg dose cohorts, respectively, in the ongoing Phase 1\/2 dose escalation study. <\/p>\n<p>In <span class=\"xn-location\">the United States<\/span>, BioMarin intends to submit two-year follow-up safety and efficacy data on all study participants from the Phase 3 GENEr8-1 study to support the benefit\/risk assessment of valoctocogene roxaparvovec, as previously requested by the Food and Drug Administration (FDA). BioMarin is targeting a Biologics License Application (BLA) resubmission in the second quarter of 2022, assuming favorable study results, followed by an expected six-month review by the FDA. <\/p>\n<p>The FDA granted Regenerative Medicine Advanced Therapy (RMAT) designation to valoctocogene roxaparvovec in\u00a0March 2021. RMAT is an expedited program intended to facilitate development and review of regenerative medicine therapies, such as valoctocogene roxaparvovec, that are intended to address an unmet medical need in patients with serious conditions. The RMAT designation is complementary to Breakthrough Therapy Designation, which the Company received in 2017.\u00a0<\/p>\n<p>In addition to the RMAT Designation and Breakthrough Therapy Designation, BioMarin&#8217;s valoctocogene roxaparvovec also has received orphan drug designation from the FDA and EMA for the treatment of severe hemophilia A.\u00a0The Orphan Drug Designation program is intended to advance the evaluation and development of products that demonstrate promise for the diagnosis and\/or treatment of rare diseases or conditions.\u00a0<\/p>\n<p>\n        <b>Robust Clinical Program<\/b>\n      <\/p>\n<p>BioMarin has multiple clinical studies underway in its comprehensive gene therapy program for the treatment of hemophilia A.\u00a0 In addition to the global Phase 3 study GENEr8-1 and the ongoing Phase 1\/2 dose escalation study, the Company is actively enrolling participants in a Phase <span class=\"xn-money\">3b<\/span>, single arm, open-label study to evaluate the efficacy and safety of valoctocogene roxaparvovec at a dose of 6e13 vg\/kg with prophylactic corticosteroids in people with hemophilia A.\u00a0 The Company is also running a Phase 1\/2 Study with the 6e13 vg\/kg dose of valoctocogene roxaparvovec in people with hemophilia A with pre-existing AAV5 antibodies, as well as another Phase 1\/2 Study with the 6e13 vg\/kg dose of valoctocogene roxaparvovec in people with hemophilia A with active or prior FVIII inhibitors.\u00a0 <\/p>\n<p>\n        <b>About Hemophilia A<\/b>\n      <\/p>\n<p>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 &lt;1%) often experience painful, spontaneous bleeds into their muscles or joints.\u00a0 Individuals with the most severe form of hemophilia A make up approximately 45 to 50 percent of the hemophilia A population.\u00a0 People with hemophilia A with moderate (FVIII 1-5%) or mild (FVIII 5-40%) disease show a much-reduced propensity to bleed.\u00a0 The standard of care for adults 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.\u00a0 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. <\/p>\n<p>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.<\/p>\n<p>\n        <b>About ISTH<\/b>\n      <\/p>\n<p>Founded in 1969, the ISTH is the leading worldwide not-for-profit organization dedicated to advancing the understanding, prevention, diagnosis and treatment of thrombotic and bleeding disorders.
