dc.description.abstract | Background
Simplification strategies of antiretroviral treatment represent effective tools for the reduction
of drug-induced toxicity, resistance mutations in case of virological failure and costs.
Objectives
To assess the effectiveness of simplification to atazanavir/ritonavir (ATVrtv) or unboosted
atazanavir (ATV400) plus lamivudine, and if low plasma or intracellular ATV Ctrough influence
virological outcomes.
Methods
Ambispective observational study in patients with undetectable HIV-RNA who were
switched to ATVrtv or ATV400 plus lamivudine once daily. Previous virological failures (VF)
were allowed if the resistance tests showed major resistance mutation neither to ATV nor to
lamivudine. VF was defined as two consecutive plasma HIV-RNA >200 copies/mL. Effectiveness was assessed by intention-to-treat and on-treatment analyses. Plasma and intracellular ATV Ctrough were measured by LC-MS/MS.
Result
A total of 246 patients were included. At week 48, the Kaplan–Meier estimation of efficacy
within the ATVrtv and ATV400 groups were 85.9% [95% confidence interval, (CI95), 80.3–
91.4%] versus 87.6% (CI95, 80.1–94.1%) by intention-to-treat analysis (p = 0.684), and
97.7% (CI95, 95.2–100%) versus 98.8% (CI95, 97.0–100%) by on-treatment analysis (p =
0.546), respectively. Plasma and intracellular Ctrough were significantly higher with ATVrtv
than with ATV400 (geometric mean (GM), 318.3 vs. 605.9 ng/mL; p = 0.013) and (811.3 vs.2659.2 ng/mL; p = 0.001), respectively. Only 14 patients had plasma Ctrough below the suggested effective concentration for ATV (150 ng/mL). No relationship between plasma or
intracellular Ctrough and VF or blips were found.
Conclusion
Boosted or unboosted ATV plus lamivudine is effective and safe, and the lower plasma
Ctrough observed with ATV400 do not compromise the effectiveness of these simplification
regimens in long-term virologically suppressed HIV-1-infected patients. | es |
