药用药理学
1. 作用机制
这种药物通过体内二酯水解代谢为替诺福韦, 3在体内进一步代谢为细胞中的替诺福韦二磷酸替诺福韦)。替诺福韦二磷酸抑制HBV-DNA聚合酶与脱氧腺苷5 '-三磷酸酯具有竞争力, 是一种天然底物, 在被纳入 DNA后, 抑制HBV-DNA复制作为链式终止剂。二磷酸替诺福韦对哺乳动物DNA聚合酶α、β和线粒体DNA聚合酶γ的抑制作用较弱。
2. 抗病毒活性
替诺福韦与HBV HepG2 2.2.15细胞表达, 在0.14 ~ 1.5μm 的 ic 50下表现出抗乙肝病毒活性。另一方面, CC50对人体细胞的细胞毒性作用超过100微米。此外, HBV-DNA聚合酶抑制剂的恩替卡韦体外, 层压素和替比夫定 (国产未释放), 以及抗HIV-1逆转录酶抑制剂三西他滨抗乙肝病毒活性, 观察到显示加性效应的拮抗作用。
3. 阻力
在海外临床试验(gs-us-174-0102、0103、0106、0108和0121检测)中, 每年最后检查 (或在治疗停止时)病毒血液疾病(hbv-dna*400 c:400 copese/ ML)检查结果检测患者 HBV 的替诺福韦敏感性最多240周, 表明没有观察到对该制剂的耐药性的特定基因突变。
4. 交叉阻力
(1) 体外检测
替诺福韦的体外敏感性、灯剂和替比布丁耐药突变 (rtV173L、RtV173L 和 rtm204iv) 降低了HBV中野生型的0.7至3.4倍, 其中乙肝病毒 (Rt180m+rtm204iv)降低3.4倍。 HBV 中的Entecavir抗突变(rtL180M、Rt184g、rtL180M i、RtL180M & rtM250V) 已减少到06倍至6.9倍于野型, 乙肝病毒耐阿登霍韦突变(rtA181V 和 RtA181V)在乙肝病毒中减少到2.9至10倍。另外, 在治疗制剂时, rtA181T突变乙肝病毒表达的替诺福韦敏感性是野生类型的0.9倍至1.5倍。
(2) 活体试验(临床试验结果)
在国内临床试验 (LOC115912 试验) 中, 29例b型慢性肝病患者在给药开始时承认已知的与耐药性相关的HBV突变到核酸模拟制剂[adenhovir耐药相关突变(Rta181t v、rtN236T 或rta181t2/V+rtN236T): 1例, lambuzine n耐药相关突变 (Rtm204i±Rtl180m): 5例, lambuzine ine和adenhovir 耐药相关突变: 1例, 恩替卡韦耐药相关突变 (rtN236T-f2, rtN236T/G或rtm250vl):20例, 兰布定, 安登韦韦和恩替卡韦耐药相关突变: 2例], 接受了兰布辛或恩替卡韦和制剂的联合给药, 最长48周。因此, 在48周内获得了持续 HBV-DNA 的病毒效应(小于2.1 log10 copisl) 的患者, 5例患者中有4例承认与乙肝病毒耐药相关的卡玛拉嗪耐药突变, 20例中12例承认恩替卡韦耐药相关突变HBV和l初丁, 2例承认adenhovir和entecavir 耐药相关突变HBV。此外, 一个例子承认adenhovir耐药相关突变HBV, 在一个案例中, 承认Lambu季和adenhovir耐药相关突变 HBV, 负HBV-DNA被观察到48周。
在海外临床试验(GS-US-174-0102、0103、0106、0108和0121测试)中, 已知的耐药相关突变HBV在给药152例b型慢性肝病患者开始[adenhovir耐药相关突变(Rta181ss/tw, RtN236T或Rta181s/+rtN236T):14例, 灯剂耐药相关突变 (rtm204isv): 135例, adenhovir和lambuzine耐药相关突变: 3例]给予本剂。在治疗该制剂长达240周, 11例在14例患者中承认adenhovir耐药相关突变HBV, 124例在135例患者中确认了丙胺耐药相关突变HBV, 并在2例中确认HBV的2例患者中确认了腺苷和单丁胺耐药相关突变, 以持续HBV-DNA阴性(小于400copiesml)为指标的病毒效应。在5例确认Rta181st和rtN236T的HBV突变的3例患者中, 观察到HBV-DNA阴性。
适应症
随着乙肝病毒的增殖，在确认肝功能异常的乙肝慢性肝病中抑制乙肝病毒的增殖
