NCT01678131

Brief Summary

This study will evaluate the technical feasibility of using fine needle aspiration (FNA) of liver tissue to obtain vaniprevir (MK-7009) liver pharmacokinetic (PK) data, working towards identifying a minimally invasive, reproducible platform to measure liver PK. The study will be done in 2 parts. In Part 1, participants will be randomized to one of five FNA/core needle biopsy (CNB) time-point collection sequences. In Part 2, participants will be randomized to one of two possible doses of vaniprevir and will be assigned to one of five FNA/CNB time-point collection sequences; participants in Part 2 will also receive background therapy with pegylated interferon alpha-2b (Peg-IFN alpha-2b) and ribavirin (RBV). The primary hypothesis is that there is a greater than 80% posterior probability that vaniprevir concentrations are successfully obtained at least 60% of the time from FNA liver samples collected at 2 of 3 specified timepoints.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants From Whom Detectable Concentrations of Hepatic Vaniprevir Are Obtained by FNA

    Liver samples were collected by FNA at 3 of 5 of the following specified postdose timepoints: 3, 12, 24, 48 and 72 hours after a single vaniprevir dose on Day 7. The technical success of the FNA procedure was established for a participant if vaniprevir was detected from at least 2 of the 3 FNA collection timepoints.

    Day 7 up to Day 10 at 3 of the following timepoints: 3, 12, 24, 48 and 72 hours postdose

Study Arms (3)

Vaniprevir 600 mg

EXPERIMENTAL

Participants received 600 mg vaniprevir only on days 1-7, and had postdose liver biopsy done by FNA and CNB from Day 7 up to Day 10.
