简要总结
To evaluate the therapeutic equivalence between the two arms of treatment in virological and immunological response after 48 weeks and to evaluate the presence of side effects during the follow-up period.
详细描述
The efficacy of the highly active antiretroviral treatment (HAART) has been demonstrated in several clinical trials. Even so, a substantial proportion of patients do not manage to maintain correct viral suppression in daily clinical practice.
Adherence to HAART treatment is critical to obtain lasting viral suppression. Thus, factors that are related to adherence such as high pill load or takes, the complexity of the antiretroviral system, tolerability and food restrictions may have an effect on viral replication.
It has been demonstrated that simpler regimens with a scant number of tablets, without food restrictions and with a single take a day are safe, efficacious and that adherence improves.
The combination of abacavir 600 mg + lamivudine 300 mg QD in a single tablet is a novel dosage that may help increase treatment adherence.

时间窗: At 12, 24, 36 and 48 weeks
次要结局
- To evaluate the immunological efficacy (changes in CD4 and CD8 counts) of the combination studied over the follow-up period.(At 12, 24, 36 and 48 weeks.)
- To evaluate the impact of treatment on the lipid profile.(At 12, 24, 36 and 48 weeks)
