英国牛津大学John Frater联合伦敦帝国理工大学Sarah Fidler课题组近日取得一项新成果。他们的最新研究比较了抗逆转录病毒疗法单独与联合踢杀法治疗新近感染艾滋病患者的效果。2020年2月18日出版的《柳叶刀》发表了这项成果。




治疗16和18周后,仅ART组中每106个CD4+ T细胞的平均总HIV DNA为3.02 log10 拷贝,ART+V+V组为3.06 log10 拷贝,组间差异不显著。未发生治疗相关的严重不良事件。

Abstract: BackgroundAntiretroviral therapy (ART) cannot cure HIV infection because of a persistent reservoir of latently infected cells. Approaches that force HIV transcription from these cells, making them susceptible to killing—termed kick and kill regimens—have been explored as a strategy towards an HIV cure. RIVER is the first randomised trial to determine the effect of ART-only versus ART plus kick and kill on markers of the HIV reservoir.MethodsThis phase 2, open-label, multicentre, randomised, controlled trial was undertaken at six clinical sites in the UK. Patients aged 18–60 years who were confirmed as HIV-positive within a maximum of the past 6 months and started ART within 1 month from confirmed diagnosis were randomly assigned by a computer generated randomisation list to receive ART-only (control) or ART plus the histone deacetylase inhibitor vorinostat (the kick) and replication-deficient viral vector T-cell inducing vaccines encoding conserved HIV sequences ChAdV63. HIVconsv-prime and MVA.HIVconsv-boost (the kill; ART+V+V; intervention). The primary endpoint was total HIV DNA isolated from peripheral blood CD4 + T-cells at weeks 16 and 18 after randomisation. Analysis was by intention to treat. This trial is registered with, NCT02336074.FindingsBetween June 14, 2015 and Jul 11, 2017, 60 men with HIV were randomly assigned to receive either an ART-only (n=30) or an ART+V+V (n=30) regimen; all 60 participants completed the study, with no loss-to-follow-up. Mean total HIV DNA at weeks 16 and 18 after randomisation was 3·02 log 10 copies HIV DNA per 10 6 CD4 + T-cells in the ART-only group versus 3·06 log 10 copies HIV DNA per 10 6 CD4 + T-cells in ART+V+V group, with no statistically significant difference between the two groups (mean difference of 0·04 log 10 copies HIV DNA per 10 6 CD4 + T-cells [95% CI 0·03 to 0·11; p=0·26]). There were no intervention-related serious adverse events.InterpretationThis kick and kill approach conferred no significant benefit compared with ART alone on measures of the HIV reservoir. Although this does not disprove the efficacy kick and kill strategy, for future trials enhancement of both kick and kill agents will be required.
