Abstract Dihydroartemisinin-piperaquine (DP), an artemisinin-based combination therapy, is one of the most important drugs for the treatment of uncomplicated malaria, yet fundamental questions remain for assuring its optimal use in our most vulnerable populations, especially for children, and in the context of interacting antiretroviral therapies. Dolutegravir (DTG), now a first-line HIV treatment option per the updated HIV treatment guidelines, has never been studied in children in the setting of concomitant DP and its impact on DP pharmacokinetics is unknown, while lopinavir/ritonavir (LPV/r, another HIV treatment), is known to increase maximum piperaquine concentrations but the magnitude and associated risk of cardiotoxicity in children is still unclear. We plan to expand our current grant to allow us to study potential interactions between DTG and DP and to also more carefully, and safely, evaluate the potentially detrimental interaction between LPV/r and DP. This administrative supplement is requesting support to allow the study of DTG as one of three antiretrovirals that will be under evaluation. Specifically we are requesting support for the expansion of control children to include a broader age range which is necessary to age-match children who are managed on DTG. Additionally, this supplement is requesting support to permit a two phase study design that will allow us to complete a safe evaluation of the likely interaction between LPV/r / and DP (i.e. LPV/r is expected to increase piperaquine concentrations which has been associated with QTc prolongation). These two requests are to provide infrastructure support in Uganda. In summary, the results of our study has the potential to significantly impact treatment guidelines for HIV and malaria in children through this definitive study of pharmacokinetics and pharmacodynamics of DP in the setting of these antiretroviral therapies. Our overaching goal is to inform optimized DP dosing strategies for children.

抽象的 双氢青蒿素哌喹（DP）是一种以青蒿素为基础的联合疗法，是最重要的治疗药物之一。 治疗单纯性疟疾的药物，但确保其最佳效果的基本问题仍然存在 在我们最脆弱的人群中使用，特别是儿童，以及在相互作用的抗逆转录病毒药物的背景下使用 疗法。根据更新的艾滋病毒治疗指南，多替拉韦 (DTG) 现在是一线艾滋病毒治疗选择， 尚未在伴有 DP 的儿童中进行过研究，其对 DP 药代动力学的影响是 未知，而洛匹那韦/利托那韦（LPV/r，另一种 HIV 治疗方法）已知会增加哌喹的最大浓度 但儿童心脏毒性的严重程度和相关风险仍不清楚。我们计划 扩大我们当前的资助，使我们能够研究 DTG 和 DP 之间的潜在相互作用，以及更多 仔细、安全地评估 LPV/r 和 DP 之间潜在的有害相互作用。本次行政 补充品正在请求支持，以允许将 DTG 作为三种抗逆转录病毒药物之一进行研究，该药物将在 评估。具体来说，我们请求支持扩大控制儿童的范围，以涵盖更广泛的范围 年龄范围是与 DTG 管理的儿童年龄匹配所必需的。另外，本补充 正在请求支持以允许进行两阶段研究设计，这将使我们能够完成对 LPV/r / 和 DP 之间可能存在相互作用（即 LPV/r 预计会增加哌喹浓度，从而 与 QTc 延长有关）。这两个要求是提供基础设施支持 乌干达。总之，我们的研究结果有可能对以下疾病的治疗指南产生重大影响： 通过这项关于 DP 的药代动力学和药效学的权威研究，儿童中的 HIV 和疟疾 这些抗逆转录病毒疗法的背景。我们的首要目标是为以下患者提供优化的 DP 剂量策略： 孩子们。
