About this study

Official title: A Randomized Clinical Trial Using Fine Needle Aspiration For Evaluation of Hepatic Pharmacokinetics of MK-5172 in Participants With Chronic Hepatitis C

This study is divided into 2 segments, and proposes to qualify fine needle aspiration (FNA) as a platform to evaluate the hepatic pharmacokinetics of low and high oral doses of Grazoprevir (MK-5172) in non-cirrhotic participants chronically infected with hepatitis C virus (HCV). The first segment, is a procedural pilot conducted prior to the main study, that is aimed at ensuring optimal execution of the FNA procedure. During the procedural pilot, core needle biopsy (CNB) will be performed on participants as part of their standard of care, but no study drugs will be administered, nor will any procedures other than FNA be conducted. The second segment, the main study, is designed to evaluate the feasibility of measuring Grazoprevir by FNA. During the main study, drugs will be administered, and other additional procedures will be conducted.

Being tested
Peg-Interferon, Liver Samples from FNA, Liver Samples from CNB, Blood Samples, Ribavirin
Medical subject headings
Hepatitis C, Chronic

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Peg-InterferonDrug

    Also called PegIntron

    Polyethyleneglycolated Interferon alfa-2b at 1.5 ug/kg/week, administered subcutaneously, once a week, over the entire course of the study.

  • Liver Samples from FNAProcedure or surgery

    Tissue samples are collected at 3 separate visits, with each collection consisting of 3-4 fine needle aspiration (FNA) passes through the liver, guided by ultrasound.

  • Liver Samples from CNBProcedure or surgery

    Tissue samples are collected at 1 of six possible visits by core needle biopsy (CNB) of the liver.

  • Blood SamplesProcedure or surgery

    Blood is collected from multiple blood draws, with the total volume for each participant not expected to exceed 500 ml.

  • RibavirinDrug

    Also called Rebetol

    Ribavirin, 600-1400 mg administered orally, twice daily, over the entire course of the study.

  • 800 mg GrazoprevirDrug

    800 mg Grazoprevir administered orally, once per day, for 7 consecutive days.

  • 100 mg GrazoprevirDrug

    100 mg Grazoprevir administered orally, once per day, for 7 consecutive days.

  • Liver samples from CNB and FNAProcedure or surgery

    Tissue samples from the liver are collected by CNB as part of standard of care, and also by FNA during a single visit.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Peg-Interferon, Liver Samples from FNA and Liver Samples from CNB in people with Chronic Hepatitis C, run by Merck Sharp & Dohme LLC.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 14 Oct 2015. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participants from whom detectable concentrations of hepatic Grazoprevir are obtained by FNA. (time frame: Days 7-12.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Oct 2015; AzTrials last refreshed its copy on 8 Nov 2026.
