研究概览
简要总结
The purpose of this research sub-study is to learn about the levels of an antiretroviral (ARV) medication called Raltegravir, and response to HIV virus in the genital tract of HIV-positive women.
We would like to see how this study medication is tolerated, and how the body processes the study medication in women who are HIV-positive. More specifically, we are interested in how Isentress® might penetrate into the female cervicovaginal secretions thereby potentially reducing the amount of HIV in those secretions. A reduction in the amount of HIV in genital secretions may prevent female subjects from transmitting HIV to their sexual partners. This information will help the research team know how a medication such as Isentress® might be used to prevent the sexual transmission of HIV.
详细描述
Purpose: This study aims to characterize the pharmacokinetics of raltegravir in cervicovaginal fluids of HIV-infected women, and compare this to the blood plasma pharmacokinetics being obtained in the main study, CID 0706.
Participants: Six HIV-positive women from the CID 0706 study Procedures: During the pharmacokinetic visit to obtain blood plasma in the CID 0706 study, women will be asked to self-collect cervicovaginal samples using a vaginal aspirator at the following timepoints: pre-dose and 1, 2, 4, 6, 8, and 12 hours after raltegravir 400mg dose administration.
