Objectives To compare the efficacy and tolerability of indinavir (IDV)/ritonavir (RTV) at 800/100 and 400/100 mg twice daily (bid) in antiretroviral therapy (ART)-naive patients. Methods An open comparison of two groups of ART-naive patients treated with IDV/RTV 800/100 or 400/100 mg bid plus two nucleoside analogues was carried out. Viral load, CD4 cell count and tolerability were measured at baseline and at weeks 4, 12, 24 and 48. IDV plasma concentrations were measured retrospectively. Results A total of 107 patients were included in the study. Of these, 57 were treated with 800/100 and 50 with 400/100 mg IDV/RTV bid. At week 48, a viral load of <50 HIV-1 RNA copies/mL was achieved by 77 and 64% of the patients, respectively, and the median CD4 cell count increases were +171 and +164 cells/muL (intent-to-treat; P not significant), respectively. Side effects leading to protease inhibitor discontinuation occurred in 61% of subjects in the 800/100 mg group vs. 20% in the 400/100 mg group (P<0.0001). Switching from 800/100 to 400/100 mg dosage improved adverse events in 16 of 20 patients. IDV concentrations were above 0.15 mg/L in 89% of the 28 patients tested in the 400/100 mg group. Conclusions Indinavir/ritonavir 400/100 mg bid provided the same efficacy as 800/100 mg bid at 48 weeks in an ART-naive population, but safety and tolerance were significantly better for 400/100 mg, while convenience was also improved and cost was reduced.
