Abstract In a retrospective database study at two HIV treatment centres, medical records were accessed to evaluate long-term efficacy and safety parameters in all HIV-infected adults who had achieved HIV-1 RNA <50 copies/mL following the initiation of fosamprenavir (FPV)/ritonavir (RTV) 1400 mg/100 mg once-daily (QD)-containing regimens between January 2004 and January 2006. Data were available for 20 antiretroviral (ARV)-naïve patients (baseline median HIV-1 RNA 5.0 log(10) copies/mL; CD4+ cell count 307 cells/mm(3)), 30 protease inhibitor (PI)-naïve, ARV-experienced patients (HIV-1 RNA 3.6 log(10) copies/mL; CD4+ count 348 cells/mm(3)) and 25 PI-experienced patients switching to FPV/RTV100 for reasons other than virological failure (HIV-1 RNA 2.7 log(10) copies/mL; CD4+ count 328 cells/mm(3)). HIV-1 RNA <50 copies/mL was achieved in 100\% of the ARV-naïve cohort (median monitoring period, 2.4 years; range, 1.4-3.2 years), 87\% of the PI-naïve cohort (2.4 years; range, 1.2-3.4 years) and 88\% of the PI-experienced cohort (2.2 years; range, 1.0-3.2 years). Virological failure occurred in 0\%, 7\% and 8\% of the cohorts, respectively, and median CD4+ count increased above baseline by 224, 155 and 115 cells/mm(3), respectively. Change from baseline in median fasting lipids was: total cholesterol +12, -6, -2 mg/dL; low-density lipoprotein-cholesterol 0, -5, +12 mg/dL; high-density lipoprotein-cholesterol +4, +2, +7 mg/dL; triglycerides +9, -21, -65 mg/dL, respectively. In conclusion, FPV/RTV 1400/100 mg QD-containing regimens remained effective long-term in all ARV-naïve and most PI-naïve and PI-experienced HIV-infected patients.
