Summary
The objective of the study is to compare two different doses of Peg-INF-α-2A (90 or 180 ug/wk) for their ability to maintain viral control when initiated 5 weeks before ART (antiretroviral therapy) interruption in HIV positive, ART-suppressed subjects (viral load <50 copies/ml) as determined by observing the percentages of viral load measurements <400 copies/ml between the two arms over a 24-week period, corresponding to the Pegasys monotherapy period (exclusive of dual ART/Pegasys 5-week period). Primary analysis will be an "intent to treat" analysis and will address the hypothesis that two different doses of Peg-INF-α-2A (90 and 180 ug/week) will be similarly effective at inhibiting viral replication.
