Brief Summary:
To evaluate the proportion of patients with virological failure after 48 weeks of treatment with the combination of efavirenz 600 mg + lamivudine (3TC) 300 mg + abacavir 600 mg once daily as an antiretroviral simplification regimen.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| HIV Infections | Drug: efavirenz Drug: Abacavir+lamivudine | Phase 3 |
Treatment simplification is a therapeutic strategy that allows patients with controlled viral replication to switch to an easier-to-take antiretroviral system to promote long-term adherence and thus maintain controlled viral load for longer, delaying the evolution of the HIV infection.
The combination of ABC+3TC+EFV is a potent and easy-to-take regimen (2 tablets once a day) that could be suitable for the simplification of antiretroviral treatment in patients with controlled viral load with a regimen that includes 2 NRTI taken twice daily.

Primary Outcome Measures
:
- Viral load of HIV-1 at each visit with regard to the baseline visit. [ Time Frame: At 12, 24, 36 and 48 weeks ]
Secondary Outcome Measures
:
- To evaluate immunological efficacy (changes in the CD4 and CD8 counts) of the combination studied over the follow-up period. [ Time Frame: At 12, 24, 36 and 48 weeks ]
- To evaluate the tolerance and safety of the combination of abacavir+ lamivudine (in a single tablet) + efavirenz given once daily over 48-week treatment period. [ Time Frame: At 12, 24, 36 and 48 weeks ]
- To evaluate treatment adherence (assessed by a self-reported questionnaire and with graduated satisfaction scales) and patient quality of life (assessed by means of the MOS-HIV questionnaire). [ Time Frame: At 12, 24, 36 and 48 weeks ]
