ABSTRACT
The aims of these phase I trials were to evaluate the pharmacokinetic interaction between elbasvir (EBR) or grazoprevir (GZR) and buprenorphine/naloxone (BUP/NAL). Trial 1 was a single-dose trial in healthy participants. Trial 2 was a multiple-dose trial in participants on BUP/NAL maintenance therapy. Coadministration of EBR or GZR with BUP/NAL had minimal effect on the pharmacokinetics of BUP/NAL, EBR, and GZR. The geometric mean ratios (GMRs (90% CI)) for BUP, norbuprenorphine, and NAL AUC0-∞ were 0.98 (0.89-1.08), 0.97 (0.86-1.09), and 0.88 (0.78-1.00) in the presence/absence of EBR; 0.98 (0.81-1.19), 1.13 (0.97-1.32), and 1.10 (0.82-1.47) in the presence/absence of GZR. The GMRs (90% CI) for EBR and GZR AUC0-∞ in the absence/presence of BUP/NAL were 1.22 (0.98-1.52) and 0.86 (0.63-1.18). In conclusion, no dose adjustment for BUP/NAL, EBR, or GZR is required for patients with HCV infection receiving EBR/GZR and BUP/NAL maintenance therapy.
