1.  Primary:   Number of Patients With Undetectable Human Immunodeficiency Virus (HIV) Viral Load at Week 24.   [ Time Frame: 24 Weeks ]

  Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
A limitation of our study was the lack of a separate control arm. However, patients did serve as their own control by virtue of at least 6 months of HIV-1 ribonucleic acid(RNA)levels below the level of quantification before enrollment in the study.
