- Plasma HIV-1 RNA levels \< 50 copies/mL for at least 6 months at screening. Isolated measurements of plasma HIV-1 RNA levels above 50 but below 200 copies/ml (socalled blips) are allowed.
Exclusion
- Prior treatment with an NRTI other than zidovudine or lamivudine.
- Use of a triple NRTI antiretroviral regimen or a regimen including unboosted saquinavir, fusion inhibitors or hydroxyurea
- Prior virological treatment failure, defined as having had to switch antiretroviral therapy because of virologic failure in the opinion of the physician.

- Renal impairment and/or use of nephrotoxic agents which in the opinion of the investigator are a contraindication for the use of tenofovir disoproxil fumarate.
- Clinically relevant laboratory abnormalities: anemia, thrombocytopenia, leucopenia, elevated liver transaminases, elevated bilirubin, elevated amylase, elevated lipase.
- Use of co-medication, other than antiretroviral drugs, with a known pharmacological interaction with one or more of the study drugs
- Active alcohol or drug use, sufficient in the investigator's opinion to prevent compliance with the dosing schedule and evaluations (methadone and buprenorphine use is allowed, although the dose of methadone might need to be adjusted).
- Anticipated non-compliance with the protocol.
- Presence of a newly (within 30 days prior to the time of enrolment) diagnosed HIV-related opportunistic infection or condition which may interfere with the ability to comply with the study.
- Chronic active viral hepatitis or other chronic liver disease, which in the opinion of the investigator is a contraindication for the use of any of the study drugs.
- Women who have the intention to become pregnant during the study period.
- Patients who have received within 4 weeks prior to entry, or who have an anticipated need for treatment with radiation therapy or cytotoxic chemotherapeutic agents during the protocol study period.
- Patients who have taken any investigational drug 30 days prior to the start of the study
