A Single Dose Study of the Safety, Pharmacokinetics and Pharmacodynamics of MK-1064 (MK-1064-001)

September 24, 2018 updated by: Merck Sharp & Dohme LLC

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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)
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.
Up to 14 days after the last dose of study drug (Up to approximately 60 days)
Number of Participants Who Discontinued Study Due to an AE
Time Frame: Up to 14 days after the last dose of study drug (Up to approximately 60 days)
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.
Up to 14 days after the last dose of study drug (Up to approximately 60 days)
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
Time Frame: Pre-dose and 0.5, 1, 2, 3 and 4 hours post-dose
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.
Pre-dose and 0.5, 1, 2, 3 and 4 hours post-dose

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
