澳大利亚的科学家们发现了一种针对乙型肝炎病毒(HBV)感染的潜在治愈方法,在临床前模型中这种有前景的新疗法100%成功消除了感染。

现在澳大利亚的一些患者在墨尔本、珀斯和阿德莱德开展的1/2a期临床实验中,成为了世界上首批接受这种潜在疗法治疗的人群。

来自墨尔本沃尔特伊莉莎研究所(Walter and Eliza Hall Institute)的科学家们开发出了一种组合疗法——将一种抗病毒药物与美国制药公司TetraLogic Pharmaceuticals研发的抗癌药物birinapant组合到了一起。乙型肝炎是当前无法治愈的一种慢性病毒性疾病。

Marc Pellegrini博士、Greg Ebert博士和同事们开发出的这一疗法,是建立在他们对感染细胞中乙肝病毒行为的研究基础之上。两篇相关论文发布在美国国家科学院院刊(PNAS)杂志中。

Pellegrini博士说,这一疗法在临床前模型中成功治愈了乙肝病毒感染,由此促成了2014年12月启动的一项人类试验。“在临床前模型的数百次测试中我们都100%成功治愈HBV感染。”

“Birinapant在破坏乙肝病毒感染肝细胞的同时不会损伤正常细胞。而令人兴奋地是,当联合给予birinapant及当前的抗病毒药物恩替卡韦(entecavir)时,以birinapant单独给药两倍的速度清除了感染。我们希望这些有希望的结果将会在现正在墨尔本、珀斯和阿德莱德开展的人类临床实验中取得成功。”

沃尔特伊莉莎研究所和TetraLogic Pharmaceuticals公司合作开发的这种联合疗法,靶向了乙型肝炎病毒利用来让宿主肝细胞存活下去的一些细胞信号通路。

Pellegrini说,乙型肝炎病毒生存于宿主细胞之中,使得它们能够数月或数年持续存留在身体内。

“通常情况下,肝细胞会响应感染开启信号,告诉细胞‘为了更大的利益’毁灭自身,阻止进一步的感染。然而我们的研究证实,乙肝病毒强占了肝细胞的内部通讯,告诉细胞忽略感染、存活下去。Birinapant扳动了被病毒利用的细胞存活‘开关’,引起了感染细胞死亡。”
 
全球有20多亿人感染乙型肝炎病毒,大约4亿人罹患慢性HBV感染。这种病毒可以感染肝细胞,导致肝硬化和肝癌等并发症,每年造成78万人死亡。

Pellegrini说,一些疗法并非靶向病毒自身,而是让宿主细胞排除病毒,这阻止了耐药HBV病毒株的出现。“生物体要适应一种药物相对较容易,要适应宿主细胞的改变则非常困难。乙肝病毒依赖宿主的这些生存机制,因此如果无法利用它们,乙肝病毒就会死亡。病毒环境这样巨大的改变或许将成为其适应的一个大障碍。”
 
Pellegrini博士和同事们还将调查相同的策略是否适用于其他的慢性感染疾病。“一些病原体感染并驻留在宿主细胞中,其中包括诸如HIV、单纯疱疹和登革热等一些病毒疾病和结核病等细菌感染,都有可能以一种类似的方式获得治愈。”

现在墨尔本Alfred医院的核心网络、珀斯Sir Charles Gardiner医院的线性临床研究,以及阿德莱德皇家阿德莱德医院IDT CMAX,都在为临床试验招募患者。

福音:FDA批准功能性治愈乙肝新药ARC-520的临床研究

在医学界流行着这样的一句话,自有人类以来,还没有谁能够解救了全球几亿病患者(乙肝患者);因此谁发明了治愈乙肝的药,谁就应得诺贝尔奖和中国最高科技奖或人类文明进步特等奖。 在全球范围内,有多达3.5-4亿乙肝患者,该病可导致肝硬化,是全球80%原发性肝癌的直接病因。中国是乙肝大国,据保守估计,全国13亿人口中有1亿慢性乙型肝炎病毒(HBV)感染者,约占全球乙肝携带者的1/3,而且我国乙肝发病率

Hepatology:乙肝肝硬化失代偿抗病毒治疗的远期效果

为了明确乙肝失代偿期肝硬化抗病毒治疗后的远期效果,来自韩国的一家研究机构进行了一项全国多中心、前瞻性、起始队列研究。 方法 研究共纳入了707例乙肝肝硬化失代偿期患者,其中包括了284例未抗病毒治疗患者和424例经过抗病毒治疗的患者(其中58例在发生失代偿期前就开始抗病毒治疗,253例在失代偿期早期开始,112例在晚期开始)。主要终点事件为5年肝移植后生存率,次要终点事件包括病毒学/血清学应答

JAMA:预防淋巴瘤化疗患者乙肝复发,恩替卡韦or拉米夫定?

尽管接受了拉米夫定预防性治疗,乙肝病毒复发仍然是淋巴瘤患者接受利妥昔单抗在内的化疗后出现的非常严重的并发症。在选择预防性抗病毒方案的选择上仍没有定论。 比较恩替卡韦和拉米夫定在预防乙肝表面抗原阳性患者接受R-CHOP化疗方案(包括利妥昔单抗、环磷酰胺、阿霉素、长春新碱、强的松)后乙肝病毒复发的疗效。 我们进行了一项随机、开放、3期试验,数据来自全国2008年2月至2012年12月共10家医疗中

Arrowhead治疗乙肝RNA药物ARC-520临床二期研究再遇阻碍

总部位于加利福尼亚州帕萨迪纳市的生物技术公司Arrowhead是一家以开发RNAi疗法为核心的生物医药公司。众所周知,RNAi被很多人认为是充满不确定性因素的研究领域,机遇与挑战并存。Arrowhead公司现有三种RNAi药物正处于研发过程,其中ARC-520是走的最远的一个项目。此外Arrowhead公司还有治疗癌症的小分子非RNA药物Cyclosert也正处于临床二期研究过程中。然而,最近

Gut:口服抗病毒药物治疗慢乙肝患者较非活动性肝炎患者发展为肝癌的风险更大

众所周知,口服抗病毒药物治疗能够减少慢性乙型病毒性肝炎(chronic hepatitis B ,CHB)患者发展为肝细胞癌(hepatocellular carcinoma ,HCC)的风险。虽然口服核苷(酸)类似物(nucleos(t)ide analogues ,NUCs)可能使患者达到CHB的非活动状态,但是使用NUCs治疗的CHB患者相比较于非活动性CHB患者患HCC的远期风险尚未可知。
