Safety and efficacy of a double-boosted protease inhibitor combination, saquinavir and lopinavir/ritonavir, in pretreated children at 96 weeks.

BACKGROUND: This study aimed to assess the long-term efficacy, safety and use of therapeutic drug monitoring (TDM) of a double-boosted protease inhibitor (PI) combination, saquinavir (SQV) and lopinavir/ritonavir (LPV/r), in Thai HIV type-1 (HIV-1)-infected children who had failed on reverse transcriptase inhibitors.

METHODS: In total, 50 children from two sites in Thailand were treated with standard dosing of SQV and LPV/r. CD4(+) T-cell count and percentage, viral load (VL; HIV-1 RNA), minimum plasma drug concentrations (C(min)) and drug safety laboratory evaluations were monitored. Virological failure was defined as having two consecutive VL measures >400 copies/ml after week 12. An intention-to-treat analysis was performed.

RESULTS: Baseline data were a median age of 9.3 years (interquartile range [IQR] 7.1-11.2), VL 4.8 log(10) copies/ml (IQR 4.5-5.1) and CD4(+) T-cell percentage 7% (IQR 3.0-9.5). CDC classifications were N=4%, A=14%, B=68% and C=14% of participants. Median CD4(+) T-cell percentage and CD4(+) T-cell count increase were 14% (IQR 7-19) and 558 cells/mm(3) (IQR 308-782), respectively (both P<0.001). Overall, 37 (74%) children achieved VL<50 copies/ml with significant differences between sites (90% versus 63%). Over 96 weeks, 10 patients had virological failure. Total cholesterol and high-density lipoprotein increased significantly over time, whereas the triglycerides and low-density lipoprotein did not. Approximately 50% of participants reported no change in body shape, and 33%, 43% and 39% reported fatter arms, face and abdomen, respectively. LPV and SQV C(min) were high and stable over time.

CONCLUSIONS: Double-boosted SQV+LPV/r was an effective and safe alternative for a second-line regimen in children. Hypercholesterolaemia needs close follow-up. On the basis of the TDM results, PI dose reduction in this population should be considered.
