Submission is to expand HYMPAVZI indication to the treatment of hemophilia A or B patients 6 years and older with inhibitors, and pediatric patients (ages 6 to 11) without inhibitors 提交的目的是将HYMPAVZI的适应症扩展到治疗6岁及以上的伴有抑制剂的A型或B型血友病患者，以及不伴有抑制剂的儿科患者（6至11岁）。If approved, HYMPAVZI would become the first non-factor prophylactic treatment available for children aged 6 to 11 years with hemophilia B 如果获得批准，HYMPAVZI 将成为首个适用于 6 至 11 岁血友病 B 患儿的非因子预防性治疗药物。NEW YORK--(BUSINESS WIRE)-- 纽约--（商业资讯）--Pfizer Inc. (NYSE: PFE) 辉瑞公司（纽约证券交易所代码：PFE）today announced that the U.S. Food and Drug Administration (FDA) has accepted and granted Priority Review for the company’s supplemental Biologics License Application (sBLA) for HYMPAVZI 今天宣布，美国食品药品监督管理局（FDA）已接受并授予该公司关于HYMPAVZI的补充生物制品许可申请（sBLA）优先审查资格。® ®(marstacimab) to expand the approved indication to include the treatment of hemophilia A or B patients 6 years and older with inhibitors, and pediatric patients (ages 6 to 11) with hemophilia A or B without inhibitors. In the U.S., HYMPAVZI is currently approved for the treatment of patients 12 years of age and older with hemophilia A without factor VIII (FVIII) inhibitors, or hemophilia B without factor IX (FIX) inhibitors.. 将（marstacimab）的批准适应症扩大到包括治疗6岁及以上伴有抑制物的血友病A或B患者，以及6至11岁不伴有抑制物的血友病A或B儿科患者。在美国，HYMPAVZI目前被批准用于治疗12岁及以上不伴有凝血因子VIII（FVIII）抑制物的血友病A患者，或不伴有凝血因子IX（FIX）抑制物的血友病B患者。The FDA has set a Prescription Drug User Fee Act (PDUFA) action date in the second quarter of 2026. If approved, HYMPAVZI would offer a combination of bleed protection with a straightforward, once-weekly subcutaneous injection administration, requiring minimal preparation and no routine treatment-related lab monitoring for these difficult-to-treat patient populations.. 美国食品药品监督管理局（FDA）已将《处方药使用者费用法案》（PDUFA）的行动日期定在2026年第二季度。如果获得批准，HYMPAVZI将提供一种结合出血保护的治疗方案，通过每周一次的皮下注射给药，操作简单，几乎无需准备，且对于这些难以治疗的患者群体，不需要常规的治疗相关实验室监测。“There is a significant medical need for younger patients with hemophilia and for those who have developed inhibitors, which neutralize factor replacement therapies and render them ineffective,” said Michael Vincent, M.D., Ph.D., Chief Inflammation & Immunology Officer, Pfizer. “Based on the findings in the BASIS clinical trial program and if approved, we believe HYMPAVZI has the potential to become a transformative option for these patients that have limited or burdensome treatment options today. “年轻的血友病患者以及那些已产生抑制剂的患者存在显著的医疗需求，这些抑制剂会中和因子替代疗法并使其失效，”辉瑞公司首席炎症与免疫官迈克尔·文森特博士表示。“基于BASIS临床试验项目的结果，如果获得批准，我们相信HYMPAVZI有潜力成为这些目前治疗选择有限或负担沉重的患者的变革性选择。”We look forward to progressing discussions with regulators to make this medicine available for patients.”. 我们期待与监管机构进一步讨论，以使患者能够获得这种药物。Hemophilia is diagnosed in early childhood and impacts more than 800,000 people worldwide. 血友病在儿童早期被诊断出来，影响着全球超过80万人。1 1The inability of the blood to clot properly can increase the risk of painful bleeding, including inside the joints, which can cause joint scarring and damage. 血液无法正常凝结会增加痛苦出血的风险，包括关节内部出血，这可能导致关节瘢痕和损伤。2,3 2,3Children’s joints have growing cartilage and bone, which makes them particularly susceptible to damage caused by repeated bleeding episodes. 儿童的关节有生长中的软骨和骨骼，这使得他们特别容易受到反复出血事件造成的损害。4 4Inhibitors, or antibodies, develop in approximately 20% of people with hemophilia A and 3% of people with hemophilia B. People living with inhibitors to FVIII and FIX are unable to continue taking factor replacement therapies as they no longer prevent or stop bleeding episodes, particularly in individuals who are refractory to immune tolerance induction therapy.. 在大约 20% 的 A 型血友病患者和 3% 的 B 型血友病患者中会产生抑制剂或抗体。对于 FVIII 和 FIX 有抑制剂的患者，他们无法继续接受凝血因子替代疗法，因为这些疗法不能再预防或阻止出血事件，尤其是对免疫耐受诱导治疗无反应的个体。1,5,6 1，5，6“For children living with hemophilia A or B between ages 6 and 11, treatment approaches that prevent bleeds are particularly important to protect growing joints,” said Guy Young, M.D., Director, Hemostasis and Thrombosis Center at Children's Hospital, Los Angeles. “HYMPAVZI would address a critical unmet medical need for these patients and those with inhibitors if approved, particularly patients ages 6 to 11 with hemophilia B who do not have non-factor treatment options available today.”. “对于6至11岁之间患有A型或B型血友病的儿童，预防出血的治疗方案对保护正在生长的关节尤为重要，”洛杉矶儿童医院止血与血栓中心主任Guy Young博士表示。“如果获得批准，HYMPAVZI将满足这些患者以及伴有抑制物患者的迫切未满足医疗需求，特别是目前没有非因子治疗选择的6至11岁B型血友病患者。”The FDA grants Priority Review to medicines that may offer significant advances in treatment or may provide a treatment where no adequate therapy exists. Priority Review designation by the FDA shortens the standard sBLA review period by four months. FDA授予优先审查资格给那些可能在治疗方面提供重大进展或在没有适当疗法的情况下提供治疗的药物。FDA的优先审查资格将标准的sBLA审查期缩短了四个月。The FDA also granted HYMPAVZI Breakthrough Therapy Designation for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in younger pediatric (≥6 to <12 years of age) patients with hemophilia B with and without inhibitors. The FDA’s Breakthrough Therapy Designation is intended to expedite the development and review of medicines with the potential to treat a serious or life-threatening disease, when preliminary clinical evidence indicates the medicine may demonstrate substantial improvement over existing therapies.. 美国食品药品监督管理局（FDA）还授予HYMPAVZI突破性疗法认定，用于预防或减少患有B型血友病（无论是否伴有抑制物）的较年轻儿科患者（≥6至<12岁）出血事件的常规预防治疗。FDA的突破性疗法认定旨在加速开发和审查那些在初步临床证据显示可能比现有疗法有显著改进、用于治疗严重或危及生命疾病的药物。The submission for HYMPAVZI in adults and adolescents is based on efficacy and safety data from the inhibitor cohort of the Phase 3 BASIS trial ( HYMPAVZI 在成人和青少年中的提交基于第 3 阶段 BASIS 试验的抑制剂队列的有效性和安全性数据 (NCT03938792 NCT03938792). The submission for HYMPAVZI in children aged 6 to 11 years with or without inhibitors is supported by efficacy and safety data from the Phase 3 BASIS KIDS trial ( ). 在6至11岁有或没有抑制剂的儿童中，HYMPAVZI的提交得到了3期BASIS KIDS试验的有效性和安全性数据的支持 (NCT05611801 NCT05611801). ）。 The use of HYMPAVZI for the treatment of patients 12 years and older living with hemophilia A or B with inhibitors is also under review by the European Medicines Agency. 欧洲药品管理局也在审查使用HYMPAVZI治疗12岁及以上患有A型或B型血友病伴抑制剂的患者。About HYMPAVZI 关于HYMPAVZIDiscovered by Pfizer scientists, HYMPAVZI has a unique mechanism of action that is differentiated from FVIII and FIX replacement treatments. Instead of replacing missing or insufficient clotting factors, HYMPAVZI is intentionally designed to target tissue factor pathway inhibitor (TFPI), one of the body’s natural mechanisms that inhibits the initiation of blood clotting. 辉瑞公司的科学家们发现，HYMPAVZI 具有一种独特的作用机制，与FVIII和FIX替代疗法有所不同。HYMPAVZI 并非替代缺失或不足的凝血因子，而是有意设计用于靶向组织因子途径抑制剂 (TFPI)，这是人体内抑制凝血启动的一种天然机制。By targeting the Kunitz 2 domain of TFPI, HYMPAVZI may help re-establish balance between bleeding and blood clot formation with the goal of offering a combination of bleed protection and straightforward administration.. 通过靶向TFPI的Kunitz 2域，HYMPAVZI可能有助于重新建立出血和血栓形成之间的平衡，目标是提供出血保护和简单管理的组合。HYMPAVZI is a hemophilia treatment that has received regulatory approvals in more than 40 countries for eligible patients living with hemophilia A without factor VIII inhibitors, or hemophilia B without factor IX inhibitors. HYMPAVZI was the first anti-TFPI approved in the U.S. and EU for the treatment of hemophilia A or B and the first hemophilia medicine approved in the U.S. HYMPAVZI 是一种血友病治疗药物，已在 40 多个国家获得监管批准，适用于不伴有 VIII 因子抑制物的 A 型血友病患者或不伴有 IX 因子抑制物的 B 型血友病患者。HYMPAVZI 是美国和欧盟批准的首个抗 TFPI 药物，用于治疗 A 型或 B 型血友病，同时也是美国批准的首个血友病药物。and EU to be administered via a pre-filled, auto-injector pen. For eligible people living with hemophilia B, it is the first once-weekly subcutaneous prophylactic treatment. HYMPAVZI is a subcutaneous treatment option with a once-weekly dosing schedule and minimal preparation required for each individual administration.. 并通过预填充的自动注射笔进行管理。对于符合资格的B型血友病患者，这是首个每周一次的皮下预防治疗方案。HYMPAVZI是一种每周一次的皮下治疗选择，每次使用所需的准备工作最少。About the BASIS Clinical Trial 关于BASIS临床试验The pivotal BASIS study is a global, Phase 3, open-label, multicenter study to evaluate the efficacy data and safety profile 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. BASIS 关键研究是一项全球性、III 期、开放标签、多中心研究，旨在评估 HYMPAVZI 在 12 至 <75 岁的重度 A 型血友病（定义为 FVIII <1%）或中重度至重度 B 型血友病（定义为 FIX 活性 ≤2%）青少年和成人患者中的疗效数据和安全性，无论是否伴有抑制物。The with inhibitor cohort included 48 people living with hemophilia with inhibitors who were treated with HYMPAVZI during a 12-month active treatment period (ATP) versus an on-demand intravenous regimen with bypassing agents, 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. 伴有抑制剂的队列包括48名在12个月的积极治疗期（ATP）内接受HYMPAVZI治疗的血友病伴抑制剂患者，对照组为按需静脉注射旁路制剂，作为常规护理的一部分，在六个月的观察期内进行。在ATP期间，参与者接受了预防性治疗（300毫克皮下负荷剂量的HYMPAVZI，随后每周一次150毫克皮下注射），并有可能将剂量增加至每周一次300毫克。An additional three patients in the inhibitor cohort were on routine prophylactic treatment prior to the study and not included in the primary efficacy analysis. The primary endpoint measures the treated ABR (annualized bleeding rate) during the 12-month ATP with HYMPAVZI compared to treated ABR on prior on-demand bypass therapy. 在抑制剂队列中，另有三名患者在研究开始前已接受常规预防治疗，因此未纳入主要疗效分析。主要终点是比较HYMPAVZI在12个月治疗期间的年化出血率（ABR）与之前按需旁路治疗的年化出血率。For further information, visit . 欲了解更多信息，请访问 。clinicaltrials.gov 临床试验.gov. 。About the BASIS KIDS Clinical Trial 关于BASIS KIDS临床试验 The BASIS KIDS study is a global, Phase 3, open-label study investigating the safety and efficacy of HYMPAVZI in children 1 to <18 years of age with severe hemophilia A or moderately severe to severe hemophilia B with or without inhibitors. There were 68 patients aged 6 to 11 years treated with HYMPAVZI during a 12-month ATP versus routine prophylaxis with factor replacement therapy (without inhibitor), or routine prophylaxis or on-demand treatment with bypassing agents (with inhibitor), administered as part of usual care in a 12-month period prior to enrollment. BASIS KIDS研究是一项全球性、III期、开放标签研究，旨在调查HYMPAVZI在1至未满18岁患有重度A型血友病或中重度至重度B型血友病（无论是否伴有抑制物）的儿童中的安全性和有效性。研究中有68名6至11岁的患者在12个月的ATP治疗期内接受了HYMPAVZI治疗，与之对比的是常规因子替代疗法预防治疗（无抑制物），或使用旁路制剂进行常规预防或按需治疗（有抑制物），这些对照治疗是在入组前12个月内作为常规护理的一部分进行的。During the ATP in this age group, participants received prophylaxis (a 150 mg subcutaneous loading dose of HYMPAVZI, followed by 75 mg subcutaneous once weekly) with the potential for dose escalation to 150 mg once weekly. The primary endpoint measures treated ABR during the 12-month ATP with HYMPAVZI compared to ABR on prior routine prophylaxis with factor replacement therapy, or routine prophylaxis or on-demand treatment with bypassing agents. 在此年龄段的ATP期间，参与者接受了预防治疗（150毫克皮下负荷剂量的HYMPAVZI，随后每周一次75毫克皮下注射），有可能剂量递增至每周一次150毫克。主要终点指标是比较使用HYMPAVZI在12个月ATP期间的治疗后ABR与之前常规因子替代疗法预防治疗、常规预防治疗或按需使用旁路制剂的ABR。For further information, visit . 欲了解更多信息，请访问。clinicaltrials.gov 临床试验.gov. 。About Hemophilia 关于血友病 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. 血友病是一组罕见的遗传性血液疾病，由凝血因子缺乏（A型血友病中的FVIII，B型血友病中的FIX）引起，导致无法正常凝血。血友病在儿童早期即可诊断，全球有超过80万人受到影响。1 1The inability of the blood to clot properly can increase the risk of painful bleeding, including inside the joints, which can cause joint scarring and damage. People living with hemophilia can suffer permanent joint damage following repeated bleeding episodes. 血液无法正常凝固会增加痛苦出血的风险，包括关节内出血，这可能导致关节瘢痕和损伤。血友病患者在反复出血后可能会遭受永久性关节损伤。2,3 2,3Children’s joints have growing cartilage and bone, which makes them particularly susceptible to damage caused by repeated bleeding episodes. 儿童的关节有生长中的软骨和骨骼，这使得他们特别容易受到反复出血事件造成的损害。4 4For decades, the most common treatment approach for hemophilia A and B has been factor replacement therapy, which replaces the missing clotting factors. 几十年来，血友病 A 和 B 最常见的治疗方法是因子替代疗法，该疗法补充了缺失的凝血因子。2,7 2,7Factor replacement therapies increase the amount of clotting factor in the body to levels that improve clotting, resulting in less bleeding. 因子替代疗法增加体内凝血因子的含量，使其达到改善凝血的水平，从而减少出血。2,3 2,3The 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. 静脉输液的负担被认为是部分血友病患者治疗依从性的障碍，这部分是由于不便、时间限制和静脉通路不佳所致。8,9 8,9Approximately 20% of people with hemophilia A and 3% of people with hemophilia B are unable to continue taking factor replacement therapies because they develop inhibitors to FVIII and FIX, respectively. 大约20%的A型血友病患者和3%的B型血友病患者因为分别对FVIII和FIX产生抑制剂而无法继续接受因子替代疗法。1,6,7 1,6,7These patients often have higher treatment burden, including potential complications from bleeding such as hospitalization and death, as well as higher treatment-related costs. 这些患者通常面临更高的治疗负担，包括因出血可能导致的并发症（如住院和死亡）以及更高的治疗相关费用。10,11,12 10，11，12HYMPAVZI (marstacimab-hncq) U.S. Important Safety Information HYMPAVZI（马斯塔西单抗-hncq）美国重要安全信息 Important: Before you start using HYMPAVZI, it is very important to talk to your healthcare provider about using factor VIII and factor IX products 重要提示：在您开始使用HYMPAVZI之前，非常有必要与您的医疗保健提供者讨论使用凝血因子VIII和凝血因子IX产品的事宜。(products that help blood clot but work in a different way than HYMPAVZI).
