A Single Dose Study of MK-8266 (MK-8266-001)

15. oktober 2018 opdateret af: Merck Sharp & Dohme LLC

A Single Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of MK-8266

A three panel study, to determine if MK-8266 given as a single dose is sufficiently safe and well tolerated. Panel A and B will consist of healthy young males and Panel C will consist of subjects with mild to moderate hypertension. The primary hypotheses for the study are that MK-8266 given as single doses is sufficiently safe and well tolerated to permit continued clinical investigation in healthy young male volunteers and male participants with mild-to-moderate hypertension and that in males with mild to moderate hypertension, at a single oral dose of MK-8266 that is sufficiently safe and well-tolerated, postdose mean time-weighted average across 24 hours of aortic augmentation index (TWA0-12hrs AIx) is reduced compared to placebo. A mean decrease of ≥ 5 percentage points is considered clinically meaningful.

Studieoversigt

Detaljeret beskrivelse

Three panels, each consisting of either 8 or 9 participants (8 healthy young males in Panel A and Panel B; and 9 participants with mild to moderate hypertension in Panel C) will be randomized to receive either MK-8266 or matching placebo in either a 6:2 ratio (Panel A and Panel B) or 6:3 ratio (Panel C), respectively, in up to 5 treatment (1 to 5) periods in Panel A and up to 4 treatment (1 to 4) periods in Panel B and Panel C. In all panels, doses will be escalated in a rising, fixed sequence. Some participants took study drug after fasting and some with food.

Number of Participants Who Experienced One or More Adverse Events
Tidsramme: Up to 14 days after administration of last dose of study drug in each study period (Up to 43 Days)
An adverse event (AE) is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure, that occurs during the course of the study. Participants in Arms/Groups in which MK-8266 or placebo was administered in more than one period were counted separately for each period.

An adverse event (AE) is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure, that occurs during the course of the study.

Aortic Augmentation Index - Time-Weighted Average 0-24 Hours
Tidsramme: Predose, 1.5, 3, 12, and 24 hours postdose
Central ascending aortic blood pressure augmentation index (AIx) is the percentage of the central pulse pressure attributed to the reflected pulse wave, and is an indirect measure of systemic arterial stiffness. AIx can be measured non-invasively by radial tonometry using aplanation tonometry of radial artery with the SphygmoCor Pulse Wave Analysis System Guide (SphygmoCor system). AIx was performed at prestudy to ensure an adequate waveform can be obtained. At each time point, a minimum of 2 AIx were completed in an attempt to obtain 2 acceptable quality assessments. A time weighted average was calculated. AIx was adjusted for heart rate. A decrease in the AIx of ≥5 percentage is considered clinically meaningful. Participants in Arms/Groups in which MK-8266 or placebo was administered in more than one period were counted separately for each period. The 12-hour measurement was not collected (per protocol) in all periods of Panels A and B.

Tidsramme: Predose, 0.5, 1.5, 2, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours postdose
PK is the process by which a drug is absorbed, distributed, metabolized, and eliminated by the body. AUC[0-inf] is a measure of the mean concentration levels of drug in the plasma after the dose. AUC[0-inf] was not collected, analyzed or summarized for participants receiving placebo.

Tidsramme: Predose, 0.5, 1.5, 2, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours postdose
PK is the process by which a drug is absorbed, distributed, metabolized, and eliminated by the body. Cmax is a measure of the maximum amount of drug in the plasma after the dose is given. For Panel A 1.0/0.8 mg MK-8266, the second dose was not well characterized due to limited sampling. Observed exposure likely underestimates the true exposure. Cmax was not collected, analyzed or summarized for participants receiving placebo.

PK is the process by which a drug is absorbed, distributed, metabolized, and eliminated by the body. Tmax is a measure of the time to reach the maximum concentration in the plasma after the drug dose. Tmax was not collected, analyzed or summarized for participants receiving placebo.

PK is the process by which a drug is absorbed, distributed, metabolized, and eliminated by the body. t1/2 is the time required for a given drug concentration in the plasma to decrease by 50%. Harmonic means +/- Pseudo standard deviations are displayed. t1/2 was not collected, analyzed or summarized for participants receiving placebo.

Time-Weighted Average of Heart Rate (0-12 Hours)
Tidsramme: Up to 12 hours
HR was measured with a validated automatic measuring device. Time weighted average was obtained as follows: For all HR values obtained over the 12-hour observation period, multiply the length of time that the participant spent at each HR value by that HR value, add these products together, and then divide by duration of the observation period. The length of time spent at an identified HR value was defined as the time elapsed since previous post-dose measurement, or time elapsed since drug administration, if there is no previous post-dose measurement. Participants in Arms/Groups in which MK-8266 or placebo was administered in more than one period were counted separately for each period.
