Roxadustat

SAN FRANCISCO, Dec. 15, 2025 (GLOBE NEWSWIRE) -- FibroGen, Inc. (NASDAQ: FGEN) today announced that the Office of Orphan Products Development of the U.S. Food and Drug Administration (FDA) has granted roxadustat Orphan Drug Designation for the treatment of myelodysplastic syndromes (MDS). 旧金山，2025年12月15日（环球新闻社）—— FibroGen公司（纳斯达克股票代码：FGEN）今日宣布，美国食品药品监督管理局（FDA）孤儿产品开发办公室已授予罗沙司他（roxadustat）用于治疗骨髓增生异常综合征（MDS）的孤儿药资格。“The Orphan Drug Designation granted to roxadustat for MDS underscores the significant treatment gap in this indication, and highlights patients’ need for additional convenient treatments that can provide durable response,” said Thane Wettig, Chief Executive Officer of FibroGen. “Roxadustat showed an improvement in transfusion-independence in a subset of patients with high transfusion burden in a post-hoc analysis from the Phase 3 MATTHERHORN trial, which along with its favorable tolerability profile and oral route of administration has the ability to set it apart from current second-line treatments. “罗沙司他针对MDS获得的孤儿药资格认证突显了该适应症中存在的显著治疗空白，并强调了患者对于额外便捷且能提供持久疗效的治疗方案的需求，”FibroGen首席执行官Thane Wettig表示。“在3期MATTHERHORN试验的事后分析中，罗沙司他在一部分高输血负担患者中显示出改善输血独立性的效果，加之其良好的耐受性特征和口服给药方式，使其有潜力区别于当前的二线治疗方案。”Our team is finalizing the Phase 3 protocol in this patient population for submission to the FDA in the fourth quarter of 2025.”. 我们的团队正在最终确定这一患者群体的第三阶段方案，计划于2025年第四季度提交给FDA。There are approximately 58,000 patients diagnosed with LR-MDS in the U.S. with 85% of them suffering from anemia. Anemia in patients with MDS is associated with increased risk of cardiovascular complications and the need for blood transfusions. Transfusion-dependent patients suffer higher rates of complications and decreased quality of life. 美国大约有58,000名患者被诊断为低危骨髓增生异常综合征（LR-MDS），其中85%的患者患有贫血。MDS患者的贫血与心血管并发症风险增加以及输血需求相关。依赖输血的患者并发症发生率更高，生活质量下降。Current first-line treatments lead to transfusion independence in less than 50% of patients and relief is often temporary with limited options for second line and beyond treatments. In a post-hoc analysis from the Phase 3 MATTERHORN trial, roxadustat demonstrated transfusion independence benefits compared to placebo in patients with high transfusion burden.. 当前的一线治疗使不到50%的患者脱离输血依赖，且缓解通常是暂时的，二线及后续治疗选择有限。在对3期MATTERHORN试验进行的事后分析中，罗沙司他相比安慰剂，在高输血负担的患者中显示出脱离输血依赖的益处。The FDA Orphan Drug Designation is granted to drugs intended for the treatment, diagnosis, or prevention of rare diseases that affect fewer than 200,000 people in the U.S. Benefits of the designation may include exemption from certain FDA fees, financial incentives for qualified clinical development, and seven years of market exclusivity in the U.S. FDA孤儿药资格授予用于治疗、诊断或预防美国境内少于20万人的罕见疾病的药物。该资格的好处可能包括免除某些FDA费用、合格临床开发的财政激励以及在美国七年的市场独占权。following drug approval.. 药品批准后...About Myelodysplastic Syndromes Anemia 关于骨髓增生异常综合征贫血Myelodysplastic syndromes (MDS) are a group of disorders characterized by dysfunctional progenitor blood cells and stem cells, resulting in chronic anemia in most patients. Annual incidence rates of MDS are estimated to be 4.9/100,000 adults in the U.S, of which 77% are considered lower-risk MDS. Approximately 80% of patients with MDS have anemia at the time of diagnosis, and around 60% of patients with MDS will experience severe anemia (hemoglobin <8 g/dL) at some point during the course of their disease. 骨髓增生异常综合征（MDS）是一组以造血祖细胞和干细胞功能异常为特征的疾病，大多数患者因此患有慢性贫血。据估计，美国每年每10万成年人中MDS的发病率为4.9例，其中77%被认为是低危MDS。大约80%的MDS患者在诊断时即患有贫血，约60%的MDS患者在病程中的某个阶段会出现严重贫血（血红蛋白<8 g/dL）。Anemia in patients with MDS is associated with increased risk of cardiovascular complications and the need for blood transfusion. Approximately 50% of patients with MDS require regular red blood cell transfusions. Transfusion-dependent MDS patients suffer higher rates of cardiac events, infections, and iron overload with the related complications. 骨髓增生异常综合征（MDS）患者的贫血与心血管并发症风险增加以及输血需求相关。大约50%的MDS患者需要定期进行红细胞输注。依赖输血的MDS患者发生心脏事件、感染和铁过载及相关并发症的风险更高。In addition, anemia frequently leads to significant fatigue, cognitive dysfunction, and decreased quality of life. Today, patients are routinely treated with erythropoiesis-stimulating agents (ESAs), luspatercept, imetelstat, or lenalidomide in lower-risk MDS with isolated del(5q), and hypomethylating agents (HMAs) in higher-risk disease. 此外，贫血常导致显著的疲劳、认知功能障碍和生活质量下降。目前，低危MDS伴孤立del(5q)的患者通常接受促红细胞生成剂（ESAs）、鲁沙肽、伊美司他或来那度胺治疗，而高危疾病则常用低甲基化剂（HMAs）进行治疗。Only 35-40% of patients respond to current treatments and the durability of response is short. Moreover, these treatments are challenging to dose-calibrate and can only be administered via subcutaneous injection or through IV infusion. There remains a high unmet need for the treatment of anemia associated with MDS, and new strategies that provide durable response and the convenience of oral administration are highly desired in managing patients with MDS.. 目前只有35-40%的患者对现有治疗有反应，且反应持续时间较短。此外，这些治疗方案难以进行剂量调整，只能通过皮下注射或静脉输注给药。对于与骨髓增生异常综合征（MDS）相关的贫血治疗，仍然存在高度未满足的需求，而能够提供持久反应且方便口服的新策略在管理MDS患者时备受期待。About Roxadustat 关于罗沙司他Roxadustat, an oral medication, is the first in a new class of medicines comprising HIF-PH inhibitors that promote erythropoiesis, or red blood cell production, through increased endogenous production of erythropoietin, improved iron absorption and mobilization, and downregulation of hepcidin. 罗沙司他是一种口服药物，属于新型缺氧诱导因子脯氨酰羟化酶抑制剂类药物，通过增加内源性促红细胞生成素的产生、改善铁的吸收和动员以及下调铁调素来促进红细胞的生成。Roxadustat is approved in Europe, Japan, and numerous other countries for the treatment of anemia of CKD in adult patients on dialysis (DD) and not on dialysis (NDD).
