抽象的

背景/目的:需要新的抗乙型肝炎病毒 (HBV) 药物来提高 HBsAg 血清学清除率或称为“功能性治愈”率。 Inarigivir(视黄酸诱导基因 I 激动剂)对 HBV 具有免疫调节和直接抗病毒作用。我们旨在确定 Inarigivir 治疗 HBV 感染的安全性和有效性。

患者/方法:80 名初治患者被随机分配到 4 个递增剂量队列中,以 4:1 的比例接受为期 12 周的 Inarigivir 25、50、100、200 mg 或安慰剂。然后所有患者都接受了替诺福韦治疗 12 周。

结果: HBV DNA 从基线的最小二乘 (LS) 平均减少随着 Inarigivir 剂量的增加而增加(25 mg 组为 0.6116,200 mg 组为 1.5774,安慰剂组为 0.0352)(95% CI 分别为 0.9518-0.2011 和 1.921-1.1634 )。在 Inarigivir 治疗组和安慰剂组中, HBV RNA 和 HBsAg 从基线的 LS 平均变化范围分别为 -0.3856 至 -0.5794 和 -0.1474 和 -0.0956 至 -0.1818 和 +0.0026。在替诺福韦治疗期间,Inarigivir 治疗组的 LS 平均 HBsAg 降低范围为 0.1709 至 0.3529,而安慰剂组为 0.1984。 Inarigivir 治疗组显示 ALT 从基线平均降低 23.3 至 33.8 U/L,而安慰剂组为 0.7 U/L。与 Inarigivir 和安慰剂相关的治疗中出现的不良事件分别发生在 4.7% 和 6.3% 的患者中。

结论:长达 200 mg 剂量的 12 周 Inarigivir 与 HBV DNA、HBV RNA 和抗原水平的降低有关。 Inarigivir 预处理患者在改用替诺福韦后观察到 HBsAg 降低的趋势。

Abstract

Background/aims: Novel agents acting against hepatitis B virus (HBV) are needed to improve HBsAg seroclearance or termed as "functional cure" rate. Inarigivir (retinoic acid-inducible gene I agonist) has immunomodulatory and direct antiviral actions against HBV. We aimed to determine the safety and efficacy of Inarigivir for the treatment of HBV infection.

Patients/methods: 80 treatment-naïve patients were randomized in 4 ascending dose cohorts to receive 12-week of Inarigivir 25, 50, 100, 200 mg or placebo in a ratio of 4:1. All patients were then given tenofovir for another 12 weeks.

Results: Least squares (LS) mean reductions in HBV DNA from baseline increased with higher doses of Inarigivir (0.6116 in 25 mg and 1.5774 in 200 mg groups vs. 0.0352 in placebo group)(95% CI 0.9518-0.2011 and 1.921-1.1634 respectively). LS mean changes in HBV RNA and HBsAg from baseline ranged from -0.3856 to -0.5794 vs. -0.1474 and -0.0956 to -0.1818 vs. +0.0026 in Inarigivir-treated vs. placebo groups respectively. During the tenofovir-treated period, LS mean reductions in HBsAg in the Inarigivir-treated groups ranged from 0.1709 to 0.3529 vs. 0.1984 in placebo group. Inarigivir-treated groups showed mean reductions in ALT from baseline between 23.3 and 33.8 U/L vs. 0.7 U/L in placebo group. Treatment-emergent adverse events related to Inarigivir and placebo occurred in 4.7% and 6.3% patient respectively.

Conclusions: 12-week Inarigivir up to 200 mg dose was associated with reduction of HBV DNA, HBV RNA and antigen levels. A trend for greater HBsAg reduction was observed in Inarigivir pre-treated patients after switching to tenofovir.

Keywords: HBV DNA suppression; HBsAg level; Inarigivir; retinoic acid-inducible gene 1; tenofovir.
