2025年，AAV基因治疗行业正处于"冰点期"与技术突破的交织点——跨国药企相继退出，却有产品持续商业化加速。 本文梳理全球已上市AAV产品企业的销售表现、管线战略及临床进展，为行业观察者提供全景视角。 Novartis：Zolgensma的重磅与安全挑战 Novartis的Zolgensma（脊髓性肌萎缩症SMA治疗）曾创造年销超10亿美元的"重磅炸弹"奇迹，但2022年因2名患儿急性肝衰竭死亡被加黑框警告。 尽管面临安全挑战，Novartis对AAV管线仍持积极态度：其SMA扩展适应症仍在III期临床推进，显示公司对AAV在神经肌肉疾病领域的长期信心。 CSL Behring/uniQure：HEMGENIX的高价博弈 HEMGENIX（血友病B治疗）以350万美元/剂成为"全球最贵药物"，2023年上市后市场接纳度加速，但美国初期渗透因支付审批复杂、患者筛选严格慢于预期。 uniQure负责生产，CSL推动商业化——两者均未放弃AAV管线：uniQure的技术平台仍支持新载体开发，CSL则持续优化支付模式以提升市场渗透。 Roche/Spark：Luxturna的销售滑坡与战略收缩 Roche旗下Spark的Luxturna（视网膜疾病）2023年销售额暴跌59%，从5000万美元降至2000万美元。 这导致Roche对Spark启动"根本性重组"，商誉减值24亿美元。 Roche的态度反映其对AAV管线的谨慎：可能将资源转向更成熟的眼科小分子或生物药领域。 BioMarin：ROCTAVIAN的血友病A突破 BioMarin的ROCTAVIAN（血友病A）2023年获FDA批准、EMA有条件批准。 截至2025年，其III期试验仍是全球AAV血友病管线的关键注册研究。 BioMarin持续加码AAV在血液疾病的应用，将其视为"一次性治愈"血友病的核心技术路径。 PTC Therapeutics：Upstaza的安全优势与管线扩展 PTC的Upstaza（芳香族L-氨基酸脱羧酶缺乏症）免疫原性数据优异：多数患者体内抗AAV2抗体与严重不良事件无明确关联。 PTC对AAV管线持开放态度，除Upstaza外，还在推进Sepiapterin（苯丙酮尿症PKU）、Vatiquinone（弗里德里希共济失调FA）等罕见病疗法，部分依赖AAV载体技术。 国内企业：锦篮、天泽云泰的临床突破 国内企业正成为AAV赛道的新势力： 锦篮基因的GC101（SMA）是国内首个进入III期临床的鞘内给药AAV疗法，潜在受益人群较Zolgensma扩大2.3倍； 天泽云泰的VGB-R04（血友病B）获CDE临床试验批准。 这些进展显示国内企业在AAV领域的快速崛起，正从罕见病向常见病（如代谢性肝病）拓展。 总结：冰点期的曙光与破局方向 AAV行业虽处"冰点期"，但技术突破（新型衣壳设计、免疫规避如外泌体包装）与资本重新布局（如Kriya Therapeutics获3.2亿美元融资）仍带来曙光。 上市企业中，Novartis、BioMarin、PTC及国内企业保持积极投入，而Roche、Sarepta则收缩调整。 未来，AAV的商业化成功将依赖三大方向： 安全性提升：降低肝毒性、免疫原性（如锦篮GC101的鞘内给药减少肝脏暴露）； 成本控制：通过CDMO（如药明生基的TESSA™技术）降低生产费用； 适应症扩展：从罕见病向糖尿病、心衰等常见病跨越。 AAV的"冰与火之歌"仍在继续，唯有技术与商业的双重突破，才能让"一次性治愈"的梦想惠及更多患者。 （注：本文数据来自2025年公开报告，详细临床进展可参考等搜索来源。） 精彩内容推荐： 风暴眼中的“奇迹”：追踪售价320万美元基因药Elevidys的致死事件Zolgensma：基因疗法的里程碑，如何重塑脊髓性肌萎缩症治疗格局？最近AAV领域有哪些负面消息，包括但不限于AAV给药后患者死亡或发生严重不良事件，停止或裁撤AAV相关产品等全球首例跨血脑屏障基因疗法暂停！儿童死亡敲响警钟从"救命神药"到4例死亡：基因疗法明星AT132的陨落与警示
