Abstract

PURPOSE:

Women comprise ≯50% of HIV-infected patients, yet safety, tolerability, and efficacy data in women taking antiretrovirals (ARVs) are limited. Lopinavir/ ritonavir (LPV/r)-anchored regimens are globally the most widely prescribed HIV-1 protease inhibitor regimens. The objective was to investigate the safety and efficacy of LPV/r-based therapy in women.

METHODS:

A database query yielded all available data in HIV-1-infected subjects receiving LPV/r-based triple-ARV regimens from randomized clinical trials lasting ≥48 weeks from Abbott or Abbott-supported AIDS Clinical Trials Group studies. Efficacy (HIV-1 RNA levels, CD4+ T-cell counts) and safety and tolerability (treatment discontinuation, treatment-related adverse events [AE], and clinical laboratory abnormalities) at 48 weeks were assessed for total women, women by age (≥50, <50 years) and body mass index (BMI; <25, ≥25 to <30, ≥30 kg/m2), and sex.

RESULTS:

Nine hundred ninety-two women initiated LPV/r-based therapy (of whom 79.2% were ARV-naïve), with 83.6% completing 48 weeks of treatment. There were 75.5% of women who achieved a threshold of HIV RNA <400 copies/mL by intent-to-treat, non-completer equals failure (ITT, NC = F) analysis, with a mean ± SE CD4+ T-cell count increase of 191.6 ± 4.92 cells/mm3 from baseline. Women aged ≥50 versus <50 years had higher incidence of moderate-to-severe treatment-related AEs and certain laboratory abnormalities, better virologic response (HIV RNA <400 copies/mL by ITT, NC = F), similar immunologic responses, and similar overall incidence of treatment discontinuations. Higher incidences of certain moderate-to-severe treatment-related AEs and laboratory abnormalities occurred in women with BMI ≥30 kg/m2; however, no effect of BMI on efficacy or discontinuation was observed.

CONCLUSIONS:

LPV/r-based regimens were efficacious and well-tolerated in women without marked differences based on age and BMI categories evaluated.
