(NYSE: PFE) announced today that the European Commission (EC) has granted marketing authorization for HYMPAVZI™ (marstacimab) for the routine prophylaxis of bleeding episodes in patients 12 years of age and older weighing at least 35 kg with severe hemophilia A (congenital factor VIII [FVIII] deficiency, FVIII <1%) without FVIII inhibitors or severe hemophilia B (congenital factor IX [FIX] deficiency, FIX <1%) without FIX inhibitors.\nHYMPAVZI is the first and only anti-tissue factor pathway inhibitor (anti-TFPI) approved in the European Union (EU) for the treatment of hemophilia A or B and the first hemophilia medicine approved in the EU to be administered via a pre-filled, auto-injector pen. HYMPAVZI offers a subcutaneous treatment option with a once-weekly dosing schedule and minimal preparation required for each individual administration.\n\"There is a considerable treatment burden associated with the standard-of-care options for hemophilia A and B, including time-consuming preparation and administration of infusions and injections potentially causing missed doses and an increased risk of bleeding,\" said Dr. Laurent Frenzel, Head of the Hemophilia Treatment and Research Center at the Necker-Enfants malades Hospital (Paris Cité). \"HYMPAVZI is a significant advancement for eligible patients in that it may provide bleed prevention as well as once-weekly subcutaneous administration via a pre-filled pen.\"\nHemophilia is a family of rare genetic blood diseases caused by a clotting factor deficiency (FVIII in hemophilia A, FIX in hemophilia B), impacting more than 800,000 people globally.1 Diagnosed in early childhood, hemophilia inhibits the blood’s ability to clot properly, increasing the risk of repeated bleeding inside the joints, which can lead to permanent joint damage.2,3 Despite significant progress in hemophilia treatment in recent years, many people living with the disease continue to experience bleeding episodes and manage their condition with frequent intravenous infusions that may need to be administered multiple times a week.4\n\"HYMPAVZI offers a first-in-class treatment option for people living with hemophilia, a disease that often leads to recurring joint bleeds and can impact daily activities as simple as climbing stairs,\" said Alexandre de Germay, Chief International Commercial Officer and Executive Vice President, Pfizer. \"This approval builds on Pfizer’s more than four-decade commitment to improve the standard of care in hemophilia, and we look forward to delivering this medicine that reduced bleeds as compared to factor prophylaxis and, importantly, requires limited preparation, meeting a key need for eligible patients.\"\nThe marketing authorization is based on results from the pivotal Phase 3 BASIS study (NCT03938792) that evaluated the efficacy and safety of marstacimab in adults and adolescents 12 years and older with severe hemophilia A or B without inhibitors. In the study, HYMPAVZI significantly reduced the annualized bleeding rate (ABR) for treated bleeds by 35% (ABR of 5.08 vs. 7.85, p-value 0.0376) during the 12-month active treatment period, demonstrating non-inferiority and superiority compared to routine prophylaxis (RP) with FVIII or FIX administered as part of usual care. The safety profile for HYMPAVZI was consistent with Phase 1/2 results, and the most commonly reported adverse events in the study were injection site reactions, headache, pruritus, and hypertension.\nThis marketing authorization is valid in all 27 EU member states, as well as in Iceland, Liechtenstein, and Norway. The EC approval follows the regulatory approval of HYMPAVZI in the United States in October.\nPfizer’s more than 40-year effort to advance hemophilia treatment began with the introduction of recombinant treatments and has extended to the introduction of newer, advanced treatment modalities. In addition to recent regulatory approvals for HYMPAVZI, Pfizer reported positive results from a Phase 3 program investigating a gene therapy candidate in hemophilia A (giroctocogene fitelparvovec) in July and received regulatory approvals in Europe and the U.S. for its hemophilia B gene therapy BEQVEZ™ (fidanacogene elaparvovec).\nAbout HYMPAVZI (marstacimab)Discovered by Pfizer scientists, HYMPAVZI is a rebalancing agent that targets the Kunitz 2 domain of tissue factor pathway inhibitor (TFPI), a natural anticoagulation protein that functions to prevent the formation of blood clots and restore hemostasis.\nHYMPAVZI is approved by the EC for the routine prophylaxis of bleeding episodes in patients aged 12 years and older weighing at least 35 kg with severe hemophilia A (congenital factor VIII [FVIII] deficiency, FVIII <1%) without FVIII inhibitors or severe hemophilia B (congenital factor IX [FIX] deficiency, FIX <1%) without FIX inhibitors.\nAbout the BASIS studyThe pivotal BASIS study is a global Phase 3, open-label, multicenter study to evaluate the efficacy and safety of HYMPAVZI in adolescent and adult participants ages 12 to <75 years with severe hemophilia A (defined as FVIII <1%) or moderately severe to severe hemophilia B (defined as FIX activity ≤2%) with or without inhibitors.\nThe marketing authorization is based on data from 116 people living with severe hemophilia without inhibitors who were treated with marstacimab during a 12-month active treatment period (ATP) versus a RP regimen with FVIII or FIX, administered as part of usual care in a 6-month observational period. During the ATP, participants received prophylaxis (a 300 mg subcutaneous loading dose of marstacimab, followed by 150 mg subcutaneously once weekly) with potential for dose escalation to 300 mg once weekly in patients weighing ≥ 50 kg when control of bleeding events is judged to be inadequate by the healthcare professional.\nHYMPAVZI reduced the ABR for treated bleeds by 35% after a 12-month ATP compared to RP treatment in patients with hemophilia A or B without inhibitors. In an interim analysis of the long-term extension study, a consistent reduction in mean ABR for treated bleeds of 2.79 (95% CI 1.90-4.09) was observed in up to an additional 16 months of follow-up (n=87). HYMPAVZI demonstrated non-inferiority across all bleeding-related secondary endpoints: spontaneous bleeds, joint bleeds, target joint bleeds, and total bleeds.\nThe safety profile for HYMPAVZI was consistent with Phase 1/2 results and treatment was generally well-tolerated. The most commonly reported adverse events were injection site reactions, headache, pruritus, and hypertension.\nThe inhibitor cohort of the BASIS study is ongoing, with results expected in the third quarter of 2025. Pfizer is also conducting BASIS KIDS, an open-label study investigating the safety and efficacy of marstacimab in children 1 to <18 years of age with severe hemophilia A or moderately severe to severe hemophilia B with or without inhibitors.\nAbout HemophiliaHemophilia is a family of rare genetic blood diseases caused by a clotting factor deficiency (FVIII in hemophilia A, FIX in hemophilia B), which prevents normal blood clotting. Hemophilia is diagnosed in early childhood and impacts more than 800,000 people worldwide.1 The inability of the blood to clot properly can increase the risk of painful bleeding inside the joints, which can cause joint scarring and damage. People living with hemophilia can suffer permanent joint damage following repeated bleeding episodes.2,3\nFor decades, the most common treatment approach for hemophilia A and B has been factor replacement therapy, which replaces the missing clotting factors. Factor replacement therapies increase the amount of clotting factor in the body to levels that improve clotting, resulting in less bleeding.5,6\nThe burden of intravenous infusions is believed to be a barrier to treatment adherence for some people living with hemophilia due in part to inconvenience, time constraints, and poor venous access.7,8,9,10 In a patient/physician/specialist nurse survey across six European countries, lack of time for treatment and convenience were among the leading reasons for not using the prescribed amount of clotting factor or skipping treatment administration.7\nHYMPAVZI (marstacimab) U.S. Important Safety Information\nImportant: Before you start using HYMPAVZI, it is very important to talk to your healthcare provider about using factor VIII and factor IX products (products that help blood clot but work in a different way than HYMPAVZI). You may need to use factor VIII or factor IX medicines to treat episodes of breakthrough bleeding during treatment with HYMPAVZI. Carefully follow your healthcare provider’s instructions regarding when to use factor VIII or factor IX medicines and the prescribed dose during your treatment with HYMPAVZI.\nBefore using HYMPAVZI, tell your healthcare provider about all of your medical conditions, including if you:\n\nhave a planned surgery. Your healthcare provider may stop treatment with HYMPAVZI before your surgery. Talk to your healthcare provider about when to stop using HYMPAVZI and when to start it again if you have a planned surgery.\nhave a severe short-term (acute) illness such as an infection or injury.\nare pregnant or plan to become pregnant. HYMPAVZI may harm your unborn baby.Females who are able to become pregnant:\n\n\nYour healthcare provider will do a pregnancy test before you start your treatment with HYMPAVZI.\nYou should use effective birth control (contraception) during treatment with HYMPAVZI and for at least 2 months after the last dose of HYMPAVZI.\nTell your healthcare provider right away if you become pregnant or think that you may be pregnant during treatment with HYMPAVZI.\n\n\nare breastfeeding or plan to breastfeed. It is not known if HYMPAVZI passes into your breast milk.\n\nTell your healthcare provider about all the medicines you take, including prescription medicines, over‑the‑counter medicines, vitamins, and herbal supplements.\nWhat are the possible side effects of HYMPAVZI?\nHYMPAVZI may cause serious side effects, including:\n\nblood clots (thromboembolic events). HYMPAVZI may increase the risk for your blood to clot. Blood clots may form in blood vessels in your arm, leg, lung, or head and can be life‑threatening. Get medical help right away if you develop any of these signs or symptoms of blood clots:\n  \nswelling or pain in arms or legs\nredness or discoloration in your arms or legs\nshortness of breath\npain in chest or upper back\nfast heart rate\ncough up blood\nfeel faint\nheadache\nnumbness in your face\neye pain or swelling\ntrouble seeing\n\nallergic reactions. Allergic reactions, including rash and itching have happened in people treated with HYMPAVZI. Stop using HYMPAVZI and get medical help right away if you develop any of the following symptoms of a severe allergic reaction:\n  \nswelling of your face, lips, mouth, or tongue\ntrouble breathing\nwheezing\ndizziness or fainting\nfast heartbeat or pounding in your chest\nsweating\n\n\nThe most common side effects of HYMPAVZI are injection site reactions (itching, swelling, hardening, redness, bruising, pain at the injection site), headache, and itching.\nThese are not all the possible side effects of HYMPAVZI. Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.\nThe full Prescribing Information can be found here.\nAbout Pfizer: Breakthroughs That Change Patients’ LivesAt Pfizer, we apply science and our global resources to bring therapies to people that extend and significantly improve their lives.
