Core Viewpoint - GSK's Bepirovirsen has achieved primary endpoints in two key Phase III clinical trials for chronic hepatitis B treatment, potentially leading to the first antiviral therapy that can achieve functional cure in just six months [3][4]. Group 1: Drug Development and Market Potential - Bepirovirsen is a novel antisense oligonucleotide (ASO) therapy that directly inhibits viral replication [3]. - If approved, Bepirovirsen could generate peak annual sales exceeding £2 billion (approximately $2.7 billion), bringing GSK closer to its goal of over £40 billion in annual revenue by 2031 [3]. - Analysts believe that even a 15% to 20% functional cure rate among hepatitis B patients would significantly alter global treatment outcomes [3]. Group 2: Current Treatment Landscape - Chronic hepatitis B (CHB) affects over 250 million people globally and is a leading cause of liver cancer, with over 1 million deaths attributed to it in 2022 according to WHO estimates [4]. - Current standard treatments, primarily nucleos(t)ide analogs (NAs), can effectively suppress viral replication but do not eliminate the virus, requiring lifelong medication for patients [4]. - Data indicates that standard treatments only allow 1% to 4% of patients to clear the virus over time, and these treatments may lead to complications [4]. Group 3: Implications for Future Treatment - If new therapies like Bepirovirsen are approved, there could be a fundamental shift in hepatitis B treatment outcomes in China and globally [5]. - Other pharmaceutical giants, including Roche and Johnson & Johnson, are also actively developing related therapies, indicating a competitive landscape in hepatitis B treatment innovation [5].

Bepirovirsen是一种新型反义寡核苷酸（ASO）乙肝抗病毒疗法，可直接抑制病毒复制。GSK计划于今 年第一季度正式启动Bepirovirsen的全球监管审批申请。 近日由复旦大学附属华山医院感染科张文宏教授等专家最新编撰的《中国高危人群乙型肝炎病毒再激活 防治指南（2026年版）》中援引数据，我国一般人群乙肝表面抗原（HBsAg）流行率为6.1%，慢性 HBV感染者约8600万例。 所谓"功能性治愈"，是指患者停药后在六个月或更长时间内，乙肝表面抗原（HBsAg）持续阴性且检测 不到乙肝病毒（HBV）DNA。分析师认为，即便是15%至20%的乙肝患者实现功能性治愈，这对于改变 全球乙肝治疗结局也将具有重要意义。 目前尚无其他疗法能够在停药后实现显著的功能性治愈率。投行杰富瑞分析师迈克尔·洛伊滕（Michael Leuchten）表示："GSK公布的消息意味着Bepirovirsen有望成为重磅炸弹级药物。" 如果该药物获批，将意味着全球首个仅需6个月有限疗程治疗，便可直接实现乙肝功能性治愈的抗病毒 疗法诞生。 目前针对慢性乙肝的标准治疗方案主要是核苷（酸）类似物（NA），虽然能有效抑制病毒复制，但难 ...
