About this study

Official title: A Single Dose Study to Evaluate the Safety, Pharmacokinetics and Pharmacodynamics of MK-1064

The purpose of this randomized, double-blind, placebo-controlled study is to evaluate the safety, pharmacokinetics and pharmacodynamics of rising, single oral doses MK-1064 in healthy, young, male participants. The primary pharmacokinetic hypothesis is that at least one dose of MK-1064 that is generally safe and well tolerated produces an average MK-1064 plasma concentration from 0 to 4 hours of ≥2.2 μM. Since this is an early Phase I assessment of MK-1064 in humans, the study protocol allows for modifications to the outlined dose, dosing regimen and/or clinical or laboratory procedures, if required to address study objectives and/or to ensure appropriate safety monitoring of participants.

Read the detailed description

Two panels (Panels A and B), will receive alternating single rising oral doses of MK-1064/placebo (i.e., order of administration will be Panel A 5 mg, Panel B 10 mg, Panel A 25 mg, Panel B 50 mg, and continuing in this alternating sequence). Following dosing for a given treatment period, a minimum of 3 days will elapse before administration of the next scheduled dose. After administration of each dose, safety and tolerability will be reviewed. The decision to proceed to the next Panel/Period in the alternating sequence will be contingent on acceptable safety and tolerability data from the preceding Panels/Periods.

What is being measured

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

  1. Number of Participants Who Experienced One or More Adverse Events (AEs)

    An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of study drug, whether or not considered related to the use of study drug. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition which is temporally associated with the use of study drug, is also an AE.

    Measured: Up to 14 days after the last dose of study drug (Up to approximately 60 days)

  2. Number of Participants Who Discontinued Study Due to an AE

    An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of study drug, whether or not considered related to the use of study drug. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition which is temporally associated with the use of study drug, is also an AE.

    Measured: Up to 14 days after the last dose of study drug (Up to approximately 60 days)

  3. Average Plasma Concentration From Time Zero to 4 Hours (Area Under the Plasma Drug Concentration-time Curve From Time Zero to 4 Hours [AUC0-4hr]) Following Single Doses of MK-1064

    AUC0-4hr is the area under the plasma concentration-time curve from time 0 to 4 hours post-dose. This is a measure of the average amount of study drug (MK-1064) in the blood plasma over a period of 4 hours after the dose.

    Measured: Pre-dose and 0.5, 1, 2, 3 and 4 hours post-dose

Secondary outcomes (4)
  1. Area Under the Plasma Drug Concentration-time Curve From Time Zero to Last Measurable Concentration (AUC0-last) Following Single Doses of MK-1064

    AUC0-last is the area under the plasma concentration-time curve from time zero to time of last measurable concentration. It is is a measure of the amount of study drug (MK-1064) in the blood plasma from pre-dose until the last measurable concentration of study drug could be determined.

    Measured: Pre-dose and 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 16, 24 and 48 hours post dose (all Periods); 72 hours post-dose (Periods 3 and 4 only)

  2. Maximum Observed Plasma Concentration (Cmax) Following Single Doses of MK-1064

    Cmax is the maximum (peak) concentration of study drug (MK-1064) observed in blood plasma.

    Measured: Pre-dose and 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 16, 24 and 48 hours post dose (all Periods); 72 hours post dose (Periods 3 and 4 only)

  3. Time to Cmax (Tmax) Following Single Doses of MK-1064

    Tmax is the amount of time to reach maximum (peak) plasma drug concentration following drug administration.

    Measured: Pre-dose and 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 16, 24 and 48 hours post dose (all Periods); 72 hours post dose (Periods 3 and 4 only)

  4. Apparent Terminal Half-life (t1/2) Following Single Doses of MK-1064

    t1/2 is the elimination half-life of study drug. t1/2 is the time it takes for half of the study drug (MK-1064) in the blood plama to dissipate.

    Measured: Pre-dose and 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 16, 24 and 48 hours post dose (all Periods); 72 hours post dose (Periods 3 and 4 only)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MK-1064 in people with Pharmacokinetics, 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 3 inclusion and 17 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 23 Oct 2018. 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. Some participants in this study may receive a placebo. 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 21 Jan 2016). 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?

Number of Participants Who Experienced One or More Adverse Events (AEs) (time frame: Up to 14 days after the last dose of study drug (Up to approximately 60 days)). The study lists 3 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 23 Oct 2018.
