“国产Chinese范冰冰HD”全球首例猪肝植入国产Chinese范冰冰HD人体手术获得成功

  全球国产Chinese范冰冰HD首例猪肝植入人体手术获得成功国产Chinese范冰冰HD 成都企业提供基因编辑猪

  近日,我国异种移植领域再次取得重大进展:在空军军医大学西京医院,专家团队成功将基因编辑猪的肝脏原位植入到脑死亡患者体内,在国际上首次实现基因编辑猪肝脏对人体肝脏的完全替代。用于此次手术的基因编辑器官供体猪,由成都中科奥格生物科技有限公司(以下简称“中科奥格”)创始人潘登科领衔的团队提供。

  成都商报-红星新闻记者从中科奥格了解到,本次用于移植的一头13月龄六基因编辑供体猪,来自中科奥格DPF医用供体猪培育中心(超洁净设施),去除了病原微生物感染风险,敲除了猪对人的三种主要异种抗原:-gal、Sda、Neu5Gc,转入了补体调节蛋白CD55、CD46和凝血调节蛋白TBM。此前该类型猪仅开展猪到猴的肝脏移植,及猪到人的肾脏移植亚临床研究,验证了其安全性及有效性。

  据西京医院官方微信公众号报道,本次临床研究经过学术委员会、医学伦理委员会、器官移植委员会、动物委员会论证通过,符合国际异种移植相关要求。手术历经供体猪肝切取、患者原肝切除、新肝植入、动静脉重建、止血关腹等多个阶段,历时十余个小时,成功将由中科奥格公司提国产Chinese范冰冰HD供的800余克六基因编辑猪肝脏,以原位替换的方式植入到经过医院全力抢救、多次评估均认证为脑死亡患者体内。术中开放移植猪肝血流后,肝脏血流灌注良好,随即产生胆汁。截至目前,患者循环等基础生命体征平稳,肝功能等多项指标逐步趋于平稳,标志着手术获得成功。

  据了解,我国有近4亿肝病患者,700多万肝硬化患者,每年新增30万-50万肝衰竭患者。对于肝衰竭,肝移植是唯一有效根治方式。现实中,很多人因等不到人类供肝而失去生命,而异种肝移植不受供肝数量限制,可使更多终末期肝病患者获益,未来可能替代同种肝移植。

  近年来,中科奥格在探索性临床方面取得多项国内外首创首例进展。去年7月,中科奥格宣布完成近千万A+轮融资。
