EMBOLD data to serve as basis of efficacy and safety following discussion with the FDA 与FDA讨论后,EMBOLD数据将作为有效性和安全性的依据BOSTON, Dec. 11, 2025 (GLOBE NEWSWIRE) -- 波士顿,2025年12月11日(环球新闻社)--Praxis Precision Medicines 实践精准医药 , Inc. (NASDAQ: PRAX), a clinical-stage biopharmaceutical company translating genetic insights into the development of therapies for central nervous system (CNS) disorders characterized by neuronal excitation-inhibition imbalance, today announced the successful completion of the planned discussion with the FDA leading to the confirmation to file a New Drug Application (NDA) for relutrigine in early 2026.. 公司(纳斯达克股票代码:PRAX)是一家临床阶段的生物制药公司,致力于将基因洞察转化为针对中枢神经系统(CNS)疾病特征性神经元兴奋-抑制失衡的疗法开发,今天宣布成功完成了与FDA的计划讨论,确认将于2026年初提交瑞鲁曲汀的新药申请(NDA)。“We are very pleased with the collaborative discussions we've had with the FDA, which support our path toward an NDA submission in early 2026,” said Marcio Souza, president and chief executive officer. “Building on the unprecedented and compelling results from the EMBOLD study, where relutrigine demonstrated statistically significant and clinically meaningful improvements, we are advancing toward delivering a much-needed therapy for children living with these devastating diseases.”. “我们与FDA进行的富有成效的合作对话令我们非常满意,这为我们在2026年初提交新药申请(NDA)提供了支持,”总裁兼首席执行官马西奥·苏扎表示。“基于EMBOLD研究中前所未有的、令人信服的结果,其中relutrigine展现了统计学上显著且具有临床意义的改善,我们正朝着为患有这些毁灭性疾病的儿童提供亟需的治疗迈进。”About Relutrigine (PRAX-562) 关于Relutrigine(PRAX-562)Relutrigine is a first-in-class small molecule in development for the treatment of developmental and epileptic encephalopathies (DEEs) as a preferential inhibitor of persistent sodium current, shown to be a key driver of seizure symptoms in severe DEEs. Relutrigine’s mechanism of precision sodium channel (NaV) modulation is consistent with superior selectivity for disease-state NaV channel hyperexcitability. Relutrigine是一种首创的小分子化合物,正在开发用于治疗发育性和癫痫性脑病(DEEs),作为持久钠电流的优先抑制剂,已被证明是严重DEEs中癫痫症状的关键驱动因素。Relutrigine的精确钠通道(NaV)调节机制与对疾病状态下的NaV通道过度兴奋性的优越选择性一致。In vivo studies of relutrigine have demonstrated dose-dependent inhibition of seizures up to complete control of seizure activity in SCN2A, SCN8A and other DEE mouse models. Relutrigine has been generally well-tolerated in three Phase 1 studies and has demonstrated biomarker changes indicative of NaV channel modulation. Relutrigine的体内研究已经表明,在SCN2A、SCN8A和其他DEE小鼠模型中,该药物能够剂量依赖性地抑制癫痫发作,直至完全控制癫痫活动。Relutrigine在三项一期研究中通常具有良好的耐受性,并显示出指示NaV通道调节的生物标志物变化。Data from the Phase 2 EMBOLD study demonstrated a well-tolerated safety profile with robust, short- and long-term improvement in motor seizures in a heavily pre-treated population, alongside maintained seizure freedom in some patients with SCN2A- and SCN8A-DEE. Relutrigine has received Orphan Drug Designation (ODD) and Rare Pediatric Disease Designation from the FDA for the treatment of SCN2A-DEE, SCN8A-DEE and Dravet syndrome; as well as Breakthrough Therapy Designation (BTD), and ODD from the European Medicines Agency for the treatment of SCN2A-DEE and SCN8A-DEE. 第二阶段EMBOLD研究的数据表明,在经过大量预处理的人群中,Relutrigine具有良好的耐受性安全性,并在运动性癫痫发作方面表现出强劲的短期和长期改善,同时部分SCN2A和SCN8A发育性癫痫性脑病(DEE)患者保持无癫痫发作。Relutrigine已获得美国食品药品监督管理局(FDA)授予的孤儿药资格(ODD)和罕见儿科疾病资格,用于治疗SCN2A发育性癫痫性脑病(DEE)、SCN8A发育性癫痫性脑病(DEE)和Dravet综合征;同时还获得了欧洲药品管理局(EMA)授予的突破性疗法资格(BTD)以及用于治疗SCN2A和SCN8A发育性癫痫性脑病(DEE)的孤儿药资格。To learn more about the EMERALD and EMBOLD studies, please visit . 要了解有关 EMERALD 和 EMBOLD 研究的更多信息,请访问 。ResilienceStudies.com 韧性研究.com. 。About Praxis 关于实践Praxis Precision Medicines is a clinical-stage biopharmaceutical company translating insights from genetic epilepsies into the development of therapies for CNS disorders characterized by neuronal excitation-inhibition imbalance.
