Further study details as provided by Indiana University:

Primary Outcome Measures:
  • Flow-mediated Dilation (FMD) of the Brachial Artery [ Time Frame: Entry and four weeks ]
    FMD is measured as the percentage increase in brachial artery diameter after increase in blood flow. We measured the change in this percentage from entry (before etravirine was started) and again at four weeks after receiving etravirine.

Secondary Outcome Measures:
  • Lipid Fractions [ Time Frame: Four weeks ]
  • Insulin Sensitivity [(Homeostasis Model Assessment-Insulin Resistance (HOMA-IR)] [ Time Frame: Four weeks ]
  • Blood Pressure [ Time Frame: Four weeks ]
  • Inflammatory Biomarkers [ Time Frame: Four weeks ]
  • Endothelial Activation Biomarkers [ Time Frame: Four weeks ]

Enrollment: 28
Study Start Date: April 2009
Study Completion Date: July 2010
Primary Completion Date: March 2010 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Etravirine
    Two one-hundred mg tablets orally twice daily for four weeks
    Other Name: INTELENCETM
Detailed Description:
We hypothesize that in HIV-uninfected subjects, etravirine 200mg twice daily for four weeks will have no effect on endothelial function. The primary objective of this study is to determine the effects of etravirine 200mg twice daily given for four weeks on endothelial function, measured as flow-mediated dilation (FMD) of the brachial artery, in HIV-uninfected subjects. Secondary objectives include determination of the effects of etravirine 200mg twice daily given for four weeks on safety measures, lipid fractions, HOMA-IR, blood pressure, inflammatory parameters, and endothelial activation parameters.
