Brief Summary
The investigators' in vitro data suggest that Neurokinin-1 receptor antagonists like aprepitant will decrease the expression of CCR5, an essential co-receptor in the life cycle of HIV, in the surface of macrophages and lymphocytes to levels at least similar to those observed in patients heterozygous for the CCR5 32 mutation. Together with a direct potential antiviral effect this could alter disease progression in patients with HIV infection. The investigators' hypothesis is that aprepitant is safe, tolerable and has antiviral activity in HIV infected individuals. This is randomized, placebo controlled, double blind study to determine the safety and antiviral activity of aprepitant by comparing the change in HIV RNA viral load after 2 weeks of aprepitant monotherapy. 18 HIV infected males and females ≥ 18 years old who have early infection with CD4 cell counts ≥ 350 cells/mm3. Subjects will be randomized 1:1 to receive 375 mg of aprepitant (Emend®) or placebo.

Outcome Measures
Primary Outcomes (2)
Virologic: Change in log10 HIV-1 RNA from baseline to Day 14
For the purposes of assessing the primary analysis of efficacy of aprepitant in reducing viral load we will be assessing the difference between the log10 viral load at baseline and at 4 weeks, and constructing a 95% confidence interval around this mean difference within each dose group.
14 days
Safety: Incidence of Grade 2, 3, and 4 adverse events
The frequency of grade 2,3 and 4 adverse events for the duration of the study will be measured to assess the safety of the compund in this population. Exact binomial confidence intervals will be calculated around the event rates for any individual adverse events that occur and for the overall rate of adverse events within each body system. For each patient the highest grade occurring adverse event within each body system will be assessed. Tables for adverse events by body system and severity of adverse event will be constructed.
