  Purpose

The goal of anti-HIV therapy is to prevent HIV from replicating. Long-term control of HIV requires at least two anti-HIV drugs that are active against the virus. Drug resistance is a problem for many treatment-experienced, HIV-infected people. The purpose of this study is to determine the benefit of adding a nucleoside reverse transcriptase inhibitor (NRTI) to a new anti-HIV drug regimen for the suppression of HIV.

Detailed Description:

Two or more fully active antiretrovirals (ARVs) are recommended for successful suppression of HIV. In people infected with resistant HIV virus, finding two drugs that are fully active against HIV can be a challenge. However, the new generation of anti-HIV drugs has been designed to suppress drug-resistant HIV. These drugs include the FDA-approved protease inhibitors (PIs) darunavir and tipranavir, the investigational non-nucleoside transcriptase inhibitor (nNRTI) etravirine, the FDA-approved fusion inhibitor enfuvirtide, the recently FDA-approved CCR5 inhibitor maraviroc, and the investigational integrase inhibitor raltegravir. Also, it is not yet known whether multiple, partially-active drugs have the same rate of success in suppressing HIV. The purpose of this study is to use HIV resistance testing to predict the potency of a suggested ARV regimen using second generation ARVs and determine if the benefits of adding NRTIs to this new drug regimen outweigh the risks of drug toxicity and pill burden. All participants will have treatment experience or resistance to NRTIs, nNRTIs, and PIs, and who are receiving novel agents.

This study will have 2 steps and 3 arms. It will last for at least 75 days for all participants and will last an additional 96 weeks for those who continue to Step 2. In Step 1, all participants will remain on their current drug regimen. During this time, phenotypic and genotypic HIV resistance tests will be performed on participants' blood samples, as well as a coreceptor tropism assay. Using this information and medication history, the study team will determine the best new regimen options for each participant. Each clinician, along with the study participant, will then chose a new regimen based on the recommendations of the study team and the participant's preference.

Step 2 will begin when participants begin their new regimen. Stratification between Arms A and B or Arm C will be based on predicted activity of the new regimen. Those assigned to a regimen with higher predicted activity will be randomly assigned to Arm A or B; those assigned a regimen predicted to have lower activity will be assigned to Arm C.

Participants in Arms A and C will take their new assigned study regimen plus at least 2 NRTIs for 96 weeks. Participants in Arm B will take their new assigned study regimen with no NRTIs for 96 weeks. Participants in Arms A and B who reach virologic failure before 96 weeks will discontinue the study. Participants in Arm C who reach virologic failure before 96 weeks will remain in the study.

All participants will have 11 clinical visits. At each visit, blood collection will occur. At some visits, urine collection and quality of life and adherence questionnaires will occur. A neurocognitive assessment will occur for all participants who enter Step 2. Participants may also consent to have cerebrospinal fluid collected via lumbar puncture upon entering Step 2 and/or at Week 24. Those participants who consent to cerebrospinal fluid collection will also have neurocognitive assessments at the times of collections. Participants will be responsible for obtaining certain ARVs not provided by the study, including the ARVs they take in Step 1 and depending on which arm of Step 2 they are in.
