What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from baseline in HCV RNA viral load (log 10 copies/mL) in GT1 HCV-infected participants

    Measured: Predose on Day 1 through Day 56

  2. Change from baseline in HCV RNA viral load (log 10 copies/mL) in GT3 HCV-infected participants

    Measured: Predose on Day 1 through Day 56

  3. Number of participants experiencing clinical or laboratory adverse events (AEs)

    Measured: From first dose up to 21 days

  4. Number of participants discontinued from study treatment due to AEs

    Measured: From Day 1 through Day 7

Secondary outcomes (2)
  1. Area under the plasma concentration curve from Hour 0 to Hour 24 (AUC0-24hr) for MK-2748

    Measured: Day 1 and Day 7, predose through 24 hours post-dose

  2. Plasma concentration of MK-2748 (C24) on Day 7 of dosing

    Measured: 24 hours post-dose on Day 7

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MK-2748 in people with 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 5 inclusion and 16 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: finished, as of the sponsor's last update on 22 Jan 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Change from baseline in HCV RNA viral load (log 10 copies/mL) in GT1 HCV-infected participants (time frame: Predose on Day 1 through Day 56). The study lists 4 primary outcomes in all. 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 22 Jan 2015.
