HIV Infections
Conditions
Brief summary
This 2 arm study will evaluate the efficacy, safety and tolerability of saquinavir/ritonavir or lopinavir/ritonavir in combination with emtricitabine/tenofovir in patients with human immunodeficiency virus type 1 (HIV-1) infection who have received no prior HIV treatment. Patients will be randomized to receive either saquinavir/ritonavir 1000/100mg oral (po) twice daily (bid) + emtricitabine/tenofovir 200/300mg po once daily (qd), or lopinavir/ritonavir 400/100mg po bid + emtricitabine/tenofovir 200/300mg po qd. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.

| Change From Baseline in Cluster Differentiation Antigen 4 Positive (CD4+) Lymphocyte Count | Baseline to Week 48 | Summary statistics for change from baseline in CD4+ lymphocyte count were presented by treatment arm. Change from baseline in CD4+ lymphocyte count was derived as follows: Change from baseline = (CD4+ count at week x) - (CD4+ count at baseline). |
