Please output the extracted information in JSON format. Do not output anything except for the extracted information. Do not add any clarifying information. Do not add any fields that are not in the schema. If the text contains attributes that do not appear in the schema, please ignore them.

Input:Similar virologic and immunologic efficacy with fosamprenavir boosted with 100 mg or 200 mg of ritonavir in HIV-infected patients: results of the LESS trial.  ritonavir (RTV) effectively boosts most protease inhibitors but is associated with significant dose-dependent adverse events (AEs). In an effort to better manage toxicities through a reduced dose of RTV, this study compared fosamprenavir (FPV) boosted with RTV 100 mg (FPV/r100) or with RTV 200 mg (FPV/r200) daily. this 24-week, open-label study enrolled patients taking a FPV/r 200-containing regimen who had HIV RNA <400 copies/mL and randomized them 1:2 to continue that regimen or simplify to FPV/r100 once daily. Other medications were not altered. The primary endpoint was the percentage of patients without suspected or confirmed virologic failure (HIV RNA ≥ 400 copies/mL) through week 24 by a missing/discontinuation equals failure (M/D=F) analysis. Noninferiority criteria were demonstrated if the lower bound of the 95% confidence interval (CI) for the difference in the primary endpoint rates between groups was greater than -12. the 2 regimens met prespecified noninferiority criteria (FPV/r100, 92%; FPV/r 200, 94%; 95% CI, -9.36 to 5.12). At week 24, the percentage of patients with HIV RNA <50 copies/mL by M/ D=F was 83% in the FPV/r100 group and 85% in the FPV/r 200 group. Drug-related grade 2-4 AEs were uncommon (FPV/r100, 4%; FPV/r 200, 7%). Median changes in lipids were similar in both groups, with the exception of triglycerides (FPV/r100, -21 mg/dL; FPV/r 200, -2 mg/dL). this 24-week study demonstrated that among previously suppressed patients, once-daily FPV/r100 was similar to FPV/r 200 in virologic and immunologic effects but was associated with greater decreases from baseline in triglyceride levels.
