- To compare CD4 cell loses 24 weeks after HAART discontinuation [ Time Frame: Through 48 weeks ]
- Proportion of patients with re-initiation of HAART within 24 and 48 weeks [ Time Frame: Through 48 weeks ]
- To compare CD4 cell loses 48 weeks after HAART discontinuation [ Time Frame: Through 48 weeks ]
- To compare HIV viral loads 4, 24 and 48 weeks after HAART discontinuation:time-weighted average change from baseline through 24 and 48 weeks (DAVG24 and DAVG48) for log10 plasma HIV-1 RNA for patients with plasma HIV-1 RNA >50 copies/mL at baseline [ Time Frame: Through 48 weeks ]
- To compare HIV viral loads 4, 24 and 48 weeks after HAART discontinuation: time-weighted average change from 4 weeks through 24 and 48 weeks (DAVG24 and DAVG48) for log10 plasma HIV-1 RNA for patients with <50 copies/mL at baseline [ Time Frame: Through 48 weeks ]
- To compare HIV viral loads 4, 24 and 48 weeks after HAART discontinuation: proportion of patients with HIV RNA <400 and <50 copies/mL at 4 weeks for subjects with plasma HIV-1 RNA <50 copies/mL at baseline [ Time Frame: Through 48 weeks ]
- To compare HIV viral loads 4, 24 and 48 weeks after HAART discontinuation: compare log10 plasma HIV-1 RNA at week 4 for patients with HIV-RNA < 50 copies/mL at baseline. [ Time Frame: Through 48 weeks ]
- To compare development of new mutations in the reverse transcriptase gene 24 and 48 weeks after HAART discontinuation. [ Time Frame: Through 48 weeks ]
- Proportion of patients with any adverse event. [ Time Frame: Through 48 weeks ]
- Proportion of patients for each adverse event. [ Time Frame: Through 48 weeks ]
- Distribution of the intensity if each adverse event (the greatest intensity for each adverse event within a patient will be considered). [ Time Frame: Through 48 weeks ]
- Distribution of the relationship between the adverse effect and the study drug (the strongest relation with the study drug for each adverse event within each patient will be considered). [ Time Frame: Through 48 weeks ]
- Proportion of patients who discontinue the study prematurely (before week 48)due to adverse events. [ Time Frame: Through 48 weeks ]
- Changes in patient's quality of life analyses. [ Time Frame: Through 48 weeks ]

Ages Eligible for Study: | 18 Years and older (Adult, Senior) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
HIV-1 infection documented by confirmed positive HIV-1 antibody test and/or positive PCR for HIV-1 RNA.
- Adult patients (over 18 years of age).
- Available genotype (current or historical) showing M184V and (≥ 2 TAMs or K65R).
- CD4 cell count ≥ 350 cells/mL.
-
Patient request HAART interruption due to any of the following:
- Patient is receiving a suppressive HAART regimen but has problems with adherence,quality of life or toxicity AND there is no alternative simpler, less toxic regimen (typically patients with substantial resistance and good virological control while receiving multiple antiretrovirals).
- Due to resistance, patient is receiving a non-suppressive HAART regimen but patient is not willing to change to a new, already available, more complicated optimized salvage regimen (typically 3rd or 4th line of therapy).
- For women of childbearing potential, negative urine pregnancy test at screening visit.
- Agreement to take part in the study and sign the informed consent.
Exclusion Criteria:
Patients receiving a non-registered antiretroviral (ARV) drug.
- Patients who have < 50 HIV-RNA copies/mL while receiving an NNRTI.
- Serum HBsAg positive and patient is receiving an anti-HBV active nucleoside/nucleotide.
- Hypersensitivity to one of the components of the dosage forms of TDF or FTC, or previous history of intolerance to one of these drugs.
- Known history of drug abuse or chronic alcohol consumption that in the clinician opinion contraindicates participation in the study.
- Women who are pregnant or breast feeding or females of childbearing potential who do not use an adequate method of contraception according to the investigator's judgment.
- Current active opportunistic infection or documented infection within the previous 4 weeks.
- Documented active malignant disease (excluding Kaposi sarcoma limited to the skin).
- Renal disease with creatinine clearance < 50 mL/min.
- Concomitant use of nephrotoxic or immuno-suppressive drugs (should be stopped prior to enrollment)
- Receiving on-going therapy with systemic corticosteroids, Interleukin-2 (IL-2) or chemotherapy.
- Patients who are not to be included in the study according to the investigator's criterion.
