In this multicenter pharmacokinetic study in HIV-infected children (6-12 years), we validated the approved once-daily darunavir/ritonavir dosing recommendations.The geometric mean darunavir area under the plasma concentration-time curve was 63.1, substantially lower than the mean value observed in adults. However, all trough levels were adequate and short-term virological outcome was good. These data support the use of the darunavir/ritonavir once-daily dosing recommendations.

OBJECTIVES: Dyslipidaemia is common in perinatally HIV-infected (PHIV) youth receiving protease inhibitors (PIs). Few studies have evaluated longitudinal lipid changes in PHIV youth after switch to newer PIs. METHODS: We compared longitudinal changes in fasting lipids [total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and TC:HDL-C ratio] in PHIV youth enrolled in the Pediatric HIV/AIDS Cohort Study (PHACS) Adolescent Master Protocol (AMP) study who switched to atazanavir/ritonavir (ATV/r)- or darunavir/ritonavir (DRV/r)-based antiretroviral therapy (ART) from an older PI-based ART and those remaining on an older PI...

PURPOSE: Refractory pediatric leukemia remains one of the leading causes of death in children. Intensification of current chemotherapy regimens to improve the outcome in these children is often limited by the effects of drug resistance and cumulative toxicity. Hence, the search for newer agents and novel therapeutic approaches are urgently needed to formulate the next-generation early-phase clinical trials for these patients. MATERIALS AND METHODS: A comprehensive library of antimicrobials, including eight HIV protease inhibitors (nelfinavir [NFV], saquinavir, indinavir, ritonavir, amprenavir, atazanavir, lopinavir, and darunavir), was tested against a panel of pediatric leukemia cells by in vitro growth inhibition studies...

BACKGROUND: The most-used protease-inhibitor in children is Lopinavir-ritonavir (LPV/r), which provides durable suppression of viral load and increases CD4+T-counts. This study describes the virological outcome of the HIV-1-infected paediatric population exposed to LPV/r during 15 years in Spain. METHODOLOGY: Patients from the Madrid Cohort of HIV-1-infected-children and adolescents exposed to LPV/r as different line therapy during 2000-2014 were selected. The baseline epidemiological-clinical features, viral suppression, changes in CD4+T-CD8+T cell counts and drug susceptibility were recorded before and during LPV/r exposure...

BACKGROUND: Limited data are available for once-daily (QD) darunavir (DRV)/ritonavir (r) in the pediatric population. Coadministration of etravirine (ETR) may alter the pharmacokinetics (PK) of DRV. We evaluated the PK interactions between DRV/r (QD) and ETR QD or twice-daily (BID) in children, adolescents, and young adults. METHODS: Human immunodeficiency virus-infected subjects 9 to < 24 years old on optimized background therapy including DRV/r 800/100 mg QD alone or combined with ETR 200 mg BID or ETR 400 mg QD were enrolled...

Darunavir (Prezista®), administered in combination with ritonavir and background antiretroviral therapy, is approved in the USA and the EU for the treatment of HIV-1 infection in pediatric patients aged ≥3 years. Ritonavir-boosted darunavir provided effective virologic suppression in treatment-naïve adolescents with HIV-1 infection, according to the results of the noncomparative, phase II DIONE trial. Ritonavir-boosted darunavir also had sustained efficacy in treatment-experienced children and/or adolescents with HIV-1 infection, according to the results of the noncomparative, phase II DELPHI and ARIEL trials...

An existing population pharmacokinetic model of darunavir in adults was updated using pediatric data from two studies evaluating weight-based, once-daily dosing of darunavir/ritonavir (ARIEL, NCT00919854 and DIONE, NCT00915655). The model was then used to provide once-daily dosing recommendations for darunavir/ritonavir in pediatric patients aged ≥3 to <12 years. The final model comprised two compartments with first-order absorption and apparent clearance dependent on the concentration of α1-acid glycoprotein...
