Reporting Groups
FOTO Participants changing to 5 days on, 2 days off (FOTO). The 5/2 intermittent treatment arm will take their antiretrovirals for 5 consecutive days followed by 2 days off for 48 weeks (provided their HIV RNA remains undetectable on an ultrasensitive assay).
Control Daily regimen (7 days)• The control arm will take their antiretrovirals for 7 days a week for the first 24 weeks and then cross over to the 5/2 intermittent treatment schedule (if their HIV RNA remains undetectable on an ultrasensitive assay) for the remainder of the study.

  Baseline Characteristics

  Outcome Measures

1.  Primary:   Percentage of Participants Who Maintained Virologic Suppression (Less Than 50 RNA Cps/ml)   [ Time Frame: 24 weeks ]

2.  Secondary:   Mean CD4+ T-cell Count Increases From Baseline to Week 24.   [ Time Frame: Baseline to Week 24 ]

3.  Secondary:   Quality of Life   [ Time Frame: 4 weeks ]

4.  Secondary:   Absolute Number of Virological "Blip" Events Occurring Over 24 Weeks   [ Time Frame: Baseline to week 24 ]

5.  Secondary:   Trough Blood Levels of Efavirenz in Both Arms   [ Time Frame: 12 or 60 hours ]

6.  Secondary:   Self-reported Adherence Summary in Both Arms   [ Time Frame: 4, 12 and 24 weeks ]

7.  Secondary:   Deviation From FOTO Schedule by One Extra Dose   [ Time Frame: 4, 12, 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
Conclusions are limited by the small "n" studied. The results are only applicable to the specific drug regimen studied and thus can not be generalized to all ART. We only studied individuals already virologically undetectable.
