ACTG377--ANTIRETROVIRAL REGIMENS W/ COMBOS OF PROTEASE INHIBITORS

本研究的主要目的是比较四种治疗方案：d4T、奈韦拉平、利托那韦（A组）、d4T、3TC、奈非那韦（B组）、d4T、奈韦拉平、奈非那韦（C组）和d4T、3TC、奈韦拉平、奈非那韦（D组）在hiv感染儿童中的安全性、耐受性、病毒学效应和免疫效应。次要目标包括通过生长速度、神经发育指标的变化和基于首次新的CDC C类诊断的HIV疾病进展的时间来评估对治疗的反应。基于群体药代动力学参数的研究药物暴露估计将与病毒学反应相关。淋巴细胞增殖对召回丝裂原、微生物召回抗原和HIV抗原的反应将在治疗组中进行评估，并与病毒学抑制相关。该研究已全部注册。

The primary objectives of this study are to compare the safety, tolerance, virologic effect and immunologic effects of four treatment regimens: d4T, nevirapine, ritonavir (Arm A), d4T, 3TC, nelfinavir (Arm B), d4T, nevirapine, nelfinavir (Arm C) and d4T, 3TC, nevirapine, nelfinavir (Arm D) in HIV-infected children. Secondary objective include evaluation of the response to therapy as measured by growth velocity, changes in neurodevelopmental indices, and HIV disease progression based on time to development of the first new CDC category C diagnosis. Estimates of exposure to study drugs, based on population pharmacokinetic parameters, will be correlated to virologic responses. Lymphocyte proliferation responses to recall mitogens, microbial recall antigens, and HIV antigens will be evaluated across treatment arms and correlated with virologic inhibition. The study has been fully enrolled.
