The objective of this study was to evaluate the pharmacokinetic interaction of ritonavir-boosted BILR 355 (BILR 355/r) with emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF). This was an open-label, prospective study. For Group A, 26 healthy subjects were given FTC/TDF (200/300 mg) once daily (QD) for 7 days and then co-administered with BILR 355/r (150/100 mg) twice daily (bid) for an additional 7 days. Pharmacokinetics assessments were performed at days 7 and 14. For Group B, eight subjects were given BILR 355/r (150/100 mg) bid for 7 days. The pharmacokinetic data from Group B were also pooled with Group B subjects from other similar studies performed in parallel to this study. After co-administration with BILR 355/r, the geometric mean ratio (GMR, %) and 90% confidence interval (CI, %) of combined versus alone treatment for FTC AUC, C and C were 160 (154-166), 128 (121-136) and 223 (206-241), respectively; and for tenofovir AUC, C and C were 126 (121-132), 131 (117-146) and 132 (124-140), respectively. Co-administration with FTC/TDF resulted in an 18% increase in AUC, 14% increase in C and 19% increase in C for BILR 355. BILR 355 was well tolerated in this study. There was no evidence of increased risk of TFV or FTC toxicity upon co-administration of FTC/TDF with BILR 355/r. [ABSTRACT FROM AUTHOR] |
