Background and Aims: Chronic hepatitis B (CHB) patients with a low viral load (LVL) are currently not eligible for antiviral
treatment. However, they comprise the largest group of hepatitis B virus-infected patients and are still at risk to develop
cirrhosis or hepatocellular carcinoma. Here we present the week 48 results of a randomized trial comparing combination
treatment of peginterferon alfa-2a (Peg-IFN) and a nucleotide analogue versus no treatment for CHB patients with LVL.
Methods: 134 CHB patients (HBeAg-negative, HBV-DNA <20,000 IU/mL) were randomized 1:1:1 to receive Peg-
IFN+adefovir (arm I; n=46), Peg-IFN+tenofovir (arm II; n=45) or no treatment (arm III; n=43) for 48 weeks (ITT
population). Randomization was stratified by HBV genotype A (22%), non-A (B 7%, C 4%, D 26%, E/F/G 20%), or
indeterminate (21%). The median age was 43 years, 57% were male. Twelve patients discontinued the study before
week 48 (5 in arm I, 6 in arm II, 1 in arm III). HBsAg loss (AxSYM <0.05 IU/mL) and quantitative HBsAg level (Architect)
was determined at regular intervals, and were compared using Fisher’s, Mann-Whitney U or Wilcoxon test.
Results: At week 48, 4 patients receiving combination therapy had achieved HBsAg loss, compared to none of the
untreated patients (ITT 4.4% vs 0.0%, p=0.31). Patients with HBsAg loss were treated in arm I (n=1) and arm II (n=3),
and had HBV genotype A (n=1), B (n=1), or indeterminate (n=2). Baseline HBsAg levels were comparable between study
arms (median 3.34 log IU/mL ). In a per-protocol analysis, HBsAg level had declined significantly in all arms at week 48; -
0.33 (p<0.001), -0.22 (p<0.001), and -0.07 (p=0.02) median log reduction for arms I, II, and III, respectively. No difference
in HBsAg decline was observed between treatment arms. However, HBsAg declined more in treatment arms I (p<0.001)
and II (p=0.002) compared to the control arm III. A strong HBsAg decline of >1.0 log IU/mL was observed in 17 treated
patients (21%), but in none of the untreated patients (p<0.001). No unexpected adverse events were observed in the
treatment arms.
Conclusions: In CHB patients with a low viral load, 48 weeks of combination treatment with Peg-IFN and adefovir or
tenofovir resulted in 4.4% HBsAg loss, compared to 0.0% in the untreated control group. The significant decline in HBsAg
at week 48 may indicate a further increase in the rate of HBsAg loss during treatment-free follow-up. Week 72 results are
expected in March 2015.

背景和目的:慢性乙型肝炎(CHB)患者的病毒载量低(LVL)目前不符合抗病毒
治疗。然而,它们包括乙肝病毒感染患者的最大组和仍处于风险发展
肝硬化或肝细胞癌。在这里,我们提出了48周结果的随机试验对比组合
治疗聚乙二醇干扰素α-2a干扰素(PEG-IFN)和核苷类似物与不治疗的慢性乙肝患者的单板层积材。
方法:134 CHB患者(HBeAg阴性,HBV-DNA <20000 IU /毫升),随机1:1:1到接收PEG-
干扰素+阿德福韦(臂我; N = 46),聚乙二醇干扰素+替诺福韦(ARM II; N = 45)或不治疗(手臂III; N = 43),48周(ITT
人口)。随机进行分层HBV基因型A(22%),非A(B 7%,C 4%,D 26%,E / F / G 20%),或
不确定的(21%)。平均年龄为43岁,57%为男性。十二名病人停止了研究前
48周(在我手臂5,6臂II,1手臂III)。 HBsAg消失(AXSYM <0.05 IU / mL)和定量的HBsAg水平(建筑师)
是定期确定,并且采用Fisher,曼 - 惠特尼U或Wilcoxon检验进行比较。
结果:在48周,4例患者接受联合治疗取得了HBsAg消失,相比之下,没有一个
未经治疗的患者(ITT 4.4%比0.0%,p值= 0.31)。患者HBsAg消失在手臂治疗I(N = 1)和ARM II(N = 3),
并有HBV基因型A(N = 1),B(N = 1),或不确定(N = 2)。基线HBsAg水平是相当的研究之间
臂(中位数3.34日志IU /毫升)。在按方案分析,乙肝表面抗原水平已经在所有的武器在48周显著下降; -
0.33(P <0.001),-0.22 I,II和III,分别为(P <0.001),和-0.07(P = 0.02),平均对数减少武器。没有不同
在HBsAg的下降是治疗组之间变化。然而,更多的乙肝表面抗原在治疗组拒绝我(P <0.001)
和二(p值= 0.002)相比,控制臂三。中> 1.0强大的HBsAg下降登录IU / mL的患者中,17处理
例(21%),但在没有任何未经治疗的患者(P <0.001)的。不出意外的不良事件的观察
治疗武器。
结论:在慢性乙肝患者病毒载量低的48周联合治疗与聚乙二醇干扰素和阿德福韦或
替诺福韦导致4.4%HBsAg消失,而在未处理的对照组0.0%。在乙肝表面抗原的显著下降
在48周可指示在治疗期间无后续在HBsAg消失率的进一步增加。第72周的结果
预计在2015年三月。
