About this study

Official title: An Open-Label Study to Investigate the Single-Dose Pharmacokinetics of MK-3866 When Administered to Subjects With Moderate and Severe Hepatic Impairment

This is an open-label, single-dose, Phase 1 study to evaluate the pharmacokinetics (PK) of intravenous (IV) MK-3866 in participants with moderate and severe hepatic impairment (HI) compared to that of matched healthy participants. The primary purpose of this study is to understand the effect of HI on the plasma PK of MK-3866 in order to guide dosing recommendations for participants with HI. This study will also evaluate the safety and tolerability of MK-3866 in participants with moderate and severe HI.

What is being measured

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

  1. Area Under the Concentration-time Curve of MK-3866 From Time 0 to Infinity (AUC0-∞)

    AUC0-∞ is determined for the period up to 72 hours post-single dose. AUC0-∞ is an estimate of total plasma exposure from dosing to (extrapolated) infinity.

    Measured: Predose, 0.5 (end of infusion), 0.75, 1, 1.5, 2, 3, 4.5, 6, 8, 10, 12, 24, 48, and 72 hours postdose

  2. Area Under the Concentration-time Curve of MK-3866 From Time 0 to Last Quantifiable Concentration (AUC0-last)

    AUC0-last is determined for the period up to 72 hours post-single dose. AUC0-last is an estimate of total plasma exposure from dosing to the time of last measurable sample.

    Measured: Predose, 0.5 (end of infusion), 0.75, 1, 1.5, 2, 3, 4.5, 6, 8, 10, 12, 24, 48, and 72 hours postdose

  3. Area Under the Concentration-time Curve of MK-3866 From Time 0 to 24 Hours (AUC0-24hr)

    AUC0-24 is determined for the period up to 24 hours post-single dose. AUC0-24 is an estimate of total daily plasma exposure from dosing to 24 hours postdose.

    Measured: Predose, 0.5 (end of infusion), 0.75, 1, 1.5, 2, 3, 4.5, 6, 8, 10, 12, and 24 hours postdose

  4. Concentration at the End of Infusion (Ceoi) of MK-3866

    The plasma sample collected at end-of-infusion (0.5 hours postdose) was used to determine Ceoi.

    Measured: 0.5 (end of infusion) hours postdose

  5. Time to Maximum Concentration (Tmax) of MK-3866

    Tmax is the time at which the maximum plasma drug concentration is detected.

    Measured: Predose, 0.5 (end of infusion), 0.75, 1, 1.5, 2, 3, 4.5, 6, 8, 10, 12, 24, 48, and 72 hours postdose

  6. Apparent Terminal Half-life (t1/2) of MK-3866

    Apparent t1/2 is the elimination half-life of MK-3866 from plasma.

    Measured: Predose, 0.5 (end of infusion), 0.75, 1, 1.5, 2, 3, 4.5, 6, 8, 10, 12, 24, 48, and 72 hours postdose

  7. Clearance (CL) of MK-3866

    CL is the volume of plasma from which the study drug is completely removed per unit time.

    Measured: Predose, 0.5 (end of infusion), 0.75, 1, 1.5, 2, 3, 4.5, 6, 8, 10, 12, 24, 48, and 72 hours postdose

  8. Volume of Distribution (Vz) of MK-3866

    Vz is the apparent volume of distribution during the terminal phase.

    Measured: Predose, 0.5 (end of infusion), 0.75, 1, 1.5, 2, 3, 4.5, 6, 8, 10, 12, 24, 48, and 72 hours postdose

Secondary outcomes (4)
  1. Fraction of Dose of MK-3866 Excreted Unchanged in Urine (Fe)

    Fe is the amount of drug excreted unchanged in urine. Urine samples were collected in 4-hour intervals up to 24 hours post-dose. The study terminated prior to analysis of urine samples and therefore no data are available.

    Measured: Predose, then pooled in the following increments: 0-4, 4-8, 8-12, 12-24 hours postdose

  2. Renal Clearance (CLr) of MK-3866

    CLr is the volume of plasma from which the study drug is completely removed per unit time by the kidney (i.e., excreted into the urine). Urine samples are collected in 4-hour intervals up to 24 hours post-dose. The study terminated prior to analysis of urine samples and therefore no data are available.

    Measured: Predose, then pooled in the following increments: 0-4, 4-8, 8-12, 12-24 hours postdose

  3. Number of Participants With at Least One Adverse Event (AE)

    An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.

    Measured: Up to 14 days

  4. Number of Participants Who Discontinued the Study Due to an AE

    An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.

    Measured: Up to 14 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MK-3866 in people with Hepatic Insufficiency and Antibacterial Agents, run by Merck Sharp & Dohme LLC at 2 sites in United States.

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 10 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: stopped early, as of the sponsor's last update on 13 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Yes. Results are posted in the registry (first posted 13 Nov 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Area Under the Concentration-time Curve of MK-3866 From Time 0 to Infinity (AUC0-∞) (time frame: Predose, 0.5 (end of infusion), 0.75, 1, 1.5, 2, 3, 4.5, 6, 8, 10, 12, 24, 48, and 72 hours postdose). The study lists 8 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 13 Nov 2019; AzTrials last refreshed its copy on 8 Nov 2026.
