NEW YORK, NY, USA I October 11, 2024 I Pfizer Inc. (NYSE: PFE)announced today that the U.S. Food and Drug Administration (FDA) has approved HYMPAVZI™ (marstacimab-hncq) for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adults and pediatric patients 12 years of age and older with hemophilia A (congenital factor VIII deficiency) without factor VIII (FVIII) inhibitors, or hemophilia B (congenital factor IX deficiency) without factor IX (FIX) inhibitors. HYMPAVZI is the first and only anti-tissue factor pathway inhibitor (anti-TFPI) approved in the U.S. for the treatment of hemophilia A or B and the first hemophilia medicine approved in the U.S. to be administered via a pre-filled, auto-injector pen. HYMPAVZI can offer a subcutaneous treatment option with a once-weekly dosing schedule and minimal preparation required for each individual administration. “The approval of HYMPAVZI is a meaningful advancement for people living with hemophilia A or B without inhibitors for bleed prevention, with a generally manageable safety profile and a straightforward once-weekly subcutaneous administration,” said Suchitra S. Acharya, M.D., Director, Hemostasis and Thrombosis Center Northwell Health, Program Head, Bleeding Disorders and Thrombosis Program, Cohen Children’s Medical Center. “HYMPAVZI aims to reduce the current treatment burden by meeting an important need for these patients, including many who have required frequent, time-consuming intravenous treatment infusion regimens.” Hemophilia 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 “HYMPAVZI is Pfizer’s second hemophilia treatment to receive FDA approval this year and is the latest meaningful scientific advancement in our more than 40-year commitment to improve care for people living with hemophilia,” said Aamir Malik, Chief U.S. Commercial Officer and Executive Vice President, Pfizer. “We look forward to launching this latest medical breakthrough and to now offer three distinct classes of hemophilia medicines – an anti-TFPI, gene therapy, and recombinant factor treatments – that can meet the unique treatment needs of a wide range of patients.” Results from the Phase 3 BASIS trial ( NCT03938792 ) supported the approval of HYMPAVZI in the U.S. in adults and adolescents with hemophilia A or B without inhibitors. In the study, HYMPAVZI reduced the annualized bleeding rate (ABR) for treated bleeds by 35% and 92% after a 12-month active treatment period compared to routine prophylaxis (RP) and on-demand (OD) treatment, respectively, in patients with hemophilia A or B without inhibitors. The safety profile for HYMPAVZI was consistent with Phase 1/2 results. The most commonly reported adverse reactions (≥3% of patients) in the study were injection site reactions, headache, and pruritus. “The hemophilia community continually seeks advancements in care that can improve quality of life for our community members,” said Phil Gattone, President and CEO, National Bleeding Disorders Foundation. “We greatly appreciate Pfizer’s innovative efforts in developing this novel treatment option that addresses some of the ongoing challenges faced by people with hemophilia A and B. The availability of this therapy represents a powerful step forward in advancing care for more individuals and families in the bleeding disorders community.” The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion for marstacimab for the routine prophylaxis of bleeding episodes in adults and adolescents 12 years and older with severe hemophilia A without FVIII inhibitors, or severe hemophilia B without FIX inhibitors. In addition to HYMPAVZI, Pfizer recently received regulatory approvals for its hemophilia B gene therapy BEQVEZ™ (fidanacogene elaparvovec) in the U.S. , EU , and Canada, and announced positive results from a Phase 3 program investigating its hemophilia A gene therapy (giroctocogene fitelparvovec). About HYMPAVZI (marstacimab-hncq) 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. HYMPAVZI is approved in the U.S. for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adults and pediatric patients 12 years of age and older with hemophilia A (congenital factor VIII deficiency) without factor VIII inhibitors, or hemophilia B (congenital factor IX deficiency) without factor IX inhibitors. About the BASIS study The 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. The FDA approval is based on results from the BASIS study that included 116 people living with hemophilia without inhibitors who were treated with HYMPAVZI during a 12-month active treatment period (ATP) versus an RP and OD intravenous regimen with FVIII or FIX, administered as part of usual care in a six-month observational period. During the ATP, participants received prophylaxis (a 300 mg subcutaneous loading dose of HYMPAVZI, followed by 150 mg subcutaneously once weekly) with potential for dose escalation to 300 mg once weekly. HYMPAVZI reduced the ABR for treated bleeds by 35% and 92% after a 12-month ATP compared to RP and OD treatment, respectively, in patients with hemophilia A or B without inhibitors. In the OD group, superiority (p<0.0001) of HYMPAVZI was demonstrated across all bleeding-related secondary endpoints – spontaneous bleeds, joint bleeds, target joint bleeds, and total bleeds. In the RP group, HYMPAVZI demonstrated non-inferiority to these secondary efficacy endpoints. The safety profile for HYMPAVZI was consistent with Phase 1/2 results and treatment was generally well-tolerated. The most commonly reported adverse reactions (≥3% of patients) were injection site reactions, headache, and pruritus. The inhibitor cohort of the BASIS trial 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. About Hemophilia Hemophilia 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 For 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 In a survey of people in the U.S. receiving prophylaxis for hemophilia A or B, nearly one-third of those that receive treatment and have high compliance – defined as taking 75% or more of their prescribed infusions – stated that the time-consuming nature of prophylaxis was the most significant challenge of the regimen. 7,8 Nearly 60% of those that took less than the prescribed number of infusions reported that the time commitment was the primary reason for missing infusions. HYMPAVZI (marstacimab) U.S. Important Safety Information Important: 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. Before using HYMPAVZI, tell your healthcare provider about all of your medical conditions, including if you: Females who are able to become pregnant: Tell your healthcare provider about all the medicines you take , including prescription medicines, over‑the‑counter medicines, vitamins, and herbal supplements. What are the possible side effects of HYMPAVZI? HYMPAVZI may cause serious side effects, including: The most common side effects of HYMPAVZI are injection site reactions (itching, swelling, hardening, redness, bruising, pain at the injection site), headache, and itching. These 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.

FRIDAY, Aug. 2, 2024 -- Too many women don’t know a key warning sign of endometrial cancer, the most common cancer of the female reproductive organs, a new study shows. More than one-third (37%) of women surveyed did not know that postmenopausal bleeding is a key symptom of endometrial cancer, researchers said. Worse, 41% said they wouldn’t tell their doctor about postmenopausal bleeding if they’d only had one episode. This could be because doctors aren’t properly counseling women, the results showed. Fewer than half of the women surveyed reported that their health care professional had counseled them about postmenopausal bleeding. “There is a need for increased recognition of postmenopausal bleeding and provider counseling on postmenopausal bleeding, and educational interventions should focus on public and provider awareness of endometrial cancer risks and symptoms,” concluded the research team led by Dr. Meredith Wise , an assistant professor of obstetrics and gynecology with the University of Minnesota Medical School. Endometrial cancer occurs when cells in the inner lining of the uterus -- the endometrium -- start to grow out of control, according to the American Cancer Society (ACS). About 67,880 new cases of uterine cancer will be diagnosed this year, the ACS estimates, and 13,250 women will die from uterine cancer. There’s been a more than 2% annual increase in uterine cancer cases in the United States, partially due to increasing obesity rates among Americans, researchers said. Death rates also increased by more than 1% a year between 1999 and 2016. There’s no screening test for endometrial cancer, but the disease is frequently caught at an early stage because it has detectable symptoms like abnormal and postmenopausal bleeding, researchers said. When diagnosed at an early stage , endometrial cancer has a five-year survival rate of nearly 95%, researchers said. Meanwhile, the rate among advanced cases where the cancer has spread is less than 19%. The study involved 648 women surveyed at the Minnesota State Fair in September 2021. Of them, 145 had gone through menopause, researchers said. "This survey study highlights opportunities for improved patient counseling about abnormal and postmenopausal uterine bleeding as an early warning sign of uterine cancer. This is especially important given that the incidence and mortality rates of uterine cancer continue to increase and are notably highest in women of color," Dr. Stephanie Faubion , medical director for The Menopause Society, said in a society news release. The new study was published July 30 in the journal Menopause . Whatever your topic of interest, subscribe to our newsletters to get the best of Drugs.com in your inbox.
