BACKGROUND: The combination of didanosine, lamivudine, and efavirenz (ddI/3TC/EFV) for the initial treatment of human immunodeficiency virus type 1 (HIV-1) infection has been insufficiently analyzed in clinical trials. METHODS: We conducted an open-label, randomized study to compare the noninferiority of ddI/3TC/EFV with the lamivudine-zidovudine tablet and EFV (COM/EFV), both administered with food to improve tolerability and convenience. Patients were stratified by HIV-1 RNA level of <5.0 log(10) or > or =5.0 log(10) copies/mL. The primary end point was the percentage of patients with an HIV-1 RNA level of <50 copies/mL at week 48, determined by intention-to-treat analysis. RESULTS:Three hundred sixty-nine patients were randomized: 186 forddI/3TC/EFV treatment and 183 for COM/EFV treatment. Both groups were well matched in terms of baseline characteristics; 19.3% of patients received a Centers for Disease Control and Prevention assessment of clinical category C, median HIV RNA level was 5.0 log(10) copies/mL, and median CD4(+) cell count was 208 cells/microL. At week 48, by intention-to-treat analysis, 70% of patients in the ddI/3TC/EFV group and 63% of patients in the COM/EFV group had an HIV-1 RNA level of <50 copies/mL (treatment difference, 7.1%; 95% confidence interval, -2.39% to 16.59%). Fourteen patients (8%) in the ddI/3TC/EFV arm (not the COM/EFV arm) and 26 patients (14%) in the COM/EFV arm (not the ddI/3TC/EFV arm) [corrected] discontinued the study medication because of adverse events (P = .046). One patient (1%) in the ddI/3TC/EFV arm and 11 patients (6%) in the COM/EFV arm discontinued medication because of hematological toxicity (P = .003). CONCLUSIONS: At week 48, ddI/3TC/EFV administered once per day with food did not have results inferior to those of COM/EFV treatment. A statistically significantly higher proportion of patients in the COM/EFV arm than in the ddI/3TC/EFV arm discontinued therapy because of adverse events, mainly because of hematological toxicity.
