Effects of Etravirine on Endothelial Function in HIV-uninfected Adults: A Pilot Study
January 5, 2011 updated by: Indiana University
Effects of Etravirine (INTELENCETM) on Endothelial Function in HIV-uninfected Adults: A Pilot Study
The purpose of this study is to determine the safety and effects of etravirine, an HIV antiretroviral medication, on vascular function.
Study Overview
Status
Completed
Intervention / Treatment
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.

Description
Inclusion Criteria:
- 18 years of age or older
- Negative ELISA for HIV-1 or HIV-2 at screening

- No history of diabetes, hypertension, or dyslipidemia
- No anticipated changes or additions to other medical therapies during the course of the study
Exclusion Criteria:
- Inability to provide written, informed consent
- Known allergy/intolerance to etravirine or nitroglycerin
- Absolute neutrophil count < 750cell/mL at screening
- Hemoglobin <11g/dL at screening
- Platelet count <100,000/mL at screening

- Breastfeeding at screening and during the course of the study
- Hypotension, defined as SBP<90mmHg at time of each main study visit before brachial artery ultrasound measurements
- Receipt of investigational agents, cytotoxic chemotherapy, systemic glucocorticoids (>10mg/day of prednisone or the equivalent), or anabolic steroids within 30 days of each screening visit or each main study visit
- Use of sildenafil (Viagra or Silagra), vardenafil (Levitra), or tadalafil (Cialis), within 72 hours (before or after) of brachial artery reactivity testing
- Indwelling vascular catheters within any upper body vessel at time of brachial artery reactivity testing
- Active drug or alcohol use or dependence that, in the opinion of the investigator, would interfere with adherence to study requirements
- Acute therapy for serious infection or other serious medical illnesses (in the judgment of the site investigator) requiring systemic treatment and/or hospitalization within 14 days prior to each screening and study visit
- History of migraine headaches
- History of Raynaud's phenomenon
- History of cardiac arrythmias
- History of hypothyroidism or hyperthyroidism that is untreated (defined as a TSH outside the normal range on most recent testing during normal clinical care)
- History of carotid bruits.
- History of any tobacco use (cigarette smoking, cigar smoking, chewing tobacco) or nicotine replacement treatments (patch, gum) within one year of screening.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
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.
