Abstract
Purpose of Review

Current treatments for chronic hepatitis B (CHB) are associated with low rates of cure. Functional cure has been accepted as a viable treatment end point in CHB. There have been substantial advances in the field of RNA interference (RNAi) therapeutics across a wide range of specialties, and the clinical pipeline now encompasses CHB. This review will highlight some of the challenges in therapeutic development, the data for RNAi in CHB, and future directions for the field.
Recent Findings

Early phase clinical trials have reported good safety data for RNAi therapies in CHB and demonstrated significant reductions in quantitative HBsAg levels (qHBsAg). Animal models however suggest that in HBeAg-negative individuals, HBsAg may be derived from hepatitis B DNA integrated into the host genome, which cannot be targeted by current RNAi therapies, and may prove to be a limitation. Preliminary data is being presented from combination therapy, which may result in more robust reductions in qHBsAg; however, trials are in the early stages of recruitment.
Summary

Despite promising data that RNAi may be an effective therapeutic strategy in CHB, it is unlikely to be in the form of monotherapy. The goal for the community will be to find the right combination of RNAi therapy with other antiviral or immunomodulatory agents, to achieve functional cure with a cessation of therapy. Early phase clinical trials are continuing to recruit, and data from combination studies will provide a “pivot point” in determining whether RNAi therapies can provide a backbone to finite duration and curative CHB regimens.

抽象
审查目的

目前对慢性乙型肝炎(CHB)的治疗与治愈率低有关。功能性治疗已被认为是CHB可行的治疗终点。在广泛的专业领域中,RNA干扰(RNAi)治疗领域已取得了实质性进展,并且临床流程现已涵盖CHB。这篇综述将重点介绍治疗发展中的一些挑战,CHB中RNAi的数据以及该领域的未来方向。
最近的发现

早期临床试验报告了CHB中RNAi治疗的良好安全性数据,并证明定量HBsAg水平(qHBsAg)明显降低。但是动物模型表明,在HBeAg阴性个体中,HBsAg可能源自整合到宿主基因组中的乙型肝炎DNA,目前的RNAi治疗无法将其靶向,并且可能被证明是一种限制。目前正在提供联合治疗的初步数据,这可能会导致qHBsAg的降低更为有效。但是,试验还处于招募初期。
概要

尽管有希望的数据表明RNAi可能是CHB的有效治疗策略,但不太可能采用单一疗法的形式。社区的目标是找到RNAi治疗与其他抗病毒或免疫调节剂的正确组合,以在停止治疗的情况下实现功能性治愈。早期临床试验仍在继续进行中,组合研究的数据将为确定RNAi治疗是否可以为有限的持续时间和治愈性CHB方案提供基础提供“枢轴”。

vir公司七月开展RANi+干挠素试验,半年期。明年就会官宣,等待结果吧。敌视和仇恨干挠素的人就不要考虑了,主要是针对亲干挠素人设计的治疗方案
