Levels of Raltegravir in the Female Genital Tissue
Completed · Not applicable
Conditions studied: HIV
In brief
This study is an investigation of the pharmacokinetics of raltegravir in the tissue of the female genital tract to determine if twice-daily dosing of 400mg achieves adequate drug levels to prevent viral integration of HIV-1. The study will also assess whether drug levels change in the tissue across the different phases of the menstrual cycle. * Hypothesis #1: Twice daily dosing with raltegravir 400mg will result in intracellular concentrations that should be sufficient to suppress HIV-1 replication throughout the menstrual cycle. * Hypothesis #2: Intracellular genital raltegravir peaks will be lower and troughs higher compared to extracellular concentrations in the plasma and PMBCs (peripheral blood mononuclear cells). * Hypothesis #3: Intracellular raltegravir concentrations will be slightly lower during the luteal phase of the menstrual cycle due to cellular pumps such as p-glycoprotein, which are present in higher numbers during periods of high progesterone.
