新的长效抗逆转录病毒药物为预防艾滋病毒的暴露后预防 (PEP) 提供了一种简化的"一刀切"方法. 需要进行研究,以克服评估它们对预防艾滋病毒的有效性的挑战.
科学领域:
- 生物医学艾滋病毒预防 预防
- 抗逆转录病毒药物开发
- 临床试验设计 临床试验设计
背景情况:
- 长效抗逆转录病毒药物 (ARV) 已被批准用于HIV治疗和暴露前预防 (PrEP).
- 这些新型ARV尚未被用于暴露后预防 (PEP),这是艾滋病毒预防的关键策略.
- 简化,单剂量PEP方案可以显著改善艾滋病毒风险人群的获取和覆盖.
研究的目的:
- 讨论在人体试验中评估PEP新型长效ARV的有效性所面临的挑战.
- 提出潜在的研究设计,可以产生必要的证据,用于实施单次管理的,长效的PEP的ARVs.
- 突出简化PEP的潜力,以满足未满足的艾滋病毒预防需求.
主要方法:
- 讨论人类试验中对PEP有效性的挑战,包括低艾滋病毒感染率和短时间的随访期.
- 在PEP窗口内,探索在弱势群体中获得知情同意的伦理考虑.
- 提出新的研究设计,例如证明短期疗效,集群随机试验和非随机方法.
主要成果:
- 由于艾滋病毒感染的频率不高,以及需要快速招募 (<72小时),确定PEP的有效性具有挑战性.
- 为评估结果,建议采用创新方法,如接近零的发病率目标和快速的HIV RNA测试.
- 社区和在线药房被提议作为新的招聘场所,以改善获取机会.
结论:
- 在生成PEP有效性证据方面存在的挑战并非无法克服.
- 对新的PEP产品,特别是长效ARV的进一步研究对于扩大艾滋病毒预防选择至关重要.
- 简化,单剂量PEP疗法对提高生物医学HIV预防覆盖率具有显著的前景.

Crossover Experiments
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
