About this study

Official title: A Multiple Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of MK-8150

This randomized, double-blind, placebo-controlled, multiple-rising-dose study will evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of MK-8150 in healthy young men, in male participants with mild to moderate hypertension, in elderly male and female participants with mild to moderate hypertension, and in male and female participants with resistant hypertension. A primary study hypothesis is that there is at least one dose that does not increase heart rate (HR) to a clinically meaningful extent in male participants with mild to moderate hypertension and in elderly participants with mild to moderate hypertension on either Day 1 or the last Day of multiple dosing (Daylast), as measured by Time-weighted Average Across 24 hours (TWA0-24hrs). The hypothesis is met if mean increase (MK-8150 - placebo) in TWA0-24hrs HR in the identified groups is ≤15 beats per minute on Day 1 and Daylast.

Read the detailed description

Ten panels (Panels A-J), consisting of 103 participants in total, will be randomized to receive either MK-8150 or matching placebo.

Males (18 to 55 years of age, inclusive) with mild to moderate hypertension will be randomized in Panels A-D and will receive either MK-8150 or placebo as once daily treatment for 10 consecutive days.

Elderly males and females (65 to 80 years of age, inclusive) with mild to moderate hypertension will be included in Panels E and F and will receive a single dose of either MK-8150 or placebo on Study Day 1 followed by at least 5 days of wash-out before proceeding to once daily treatment of the same randomized treatment at a lower dose for 10 consecutive days.

Participants 18 to 65 years of age with resistant hypertension will be enrolled in Panels H and will receive in randomized sequences of MK-8150/placebo or placebo/MK-8150 in 2 treatment periods. There will be a minimum 3 weeks washout period between the 2 treatment periods in Panel H.

Healthy males (18 to 55 years of age, inclusive) will be enrolled in Panel G and will receive MK-8150 or matching placebo once daily for 28 days. Participants randomized to MK-8150 in Panel G who meet all of the dose-escalation criteria and have not met any of the hemodynamic stopping criteria will be eligible for dose increases on Day 8, Day 15, and Day 22. If dose escalation criteria are not met (or if the Investigator or Sponsor elects not to increase the dose), then the participant will continue on the current dose and will be eligible for a dose increase at the next dose-escalation decision day if all dose-escalation criteria are met at that time.

Male participants (18 to 65 years of age, inclusive) with mild to moderate hypertension will be randomized in Panels I and J. In each panel, 18 participants will receive either MK-8150 or matching placebo as once daily treatment for up to 28 consecutive days. Participants who are randomized to placebo will receive placebo throughout the study. On Days 8, 15 and 22 in both Panels I and J, participants will be eligible for dose-escalation, down-dosing, or continuing their current dose depending on their hemodynamic status. Participants in Panels I and J who meet down-dosing criteria at any time during the study will have their doses reduced to the previous well-tolerated dose level until the next dose-escalation decision day, or through the end of the study, whichever is first.

What is being measured

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

  1. Number of Participants With an Adverse Event (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 the study drug, whether or not considered related to the use of the study drug. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the use of the study drug, is also an AE. The 8 crossover Panel H participants are represented in both Panel H - MK-8150 10/20 mg column and Placebo (Panel A - J) column.

    Measured: Up to 14 days after the last dose (Up to approximately 42 days, excluding pre-dose/screening period)

  2. Number of Participants Discontinued From Study Drug Due to Meeting Hemodynamic Stopping Rules

    Hemodynamic criteria for stopping drug dosing were applied (any of the following, obtained resting and if present for ≥1 hour, unless noted). For all Panels: HR >120 bpm; SBP ≥180 mm Hg (Panels A-D/G-J) and ≥175 mm Hg (Panels E-F); DBP ≥110 mm Hg; DBP <50 mm Hg; SBP <90 mm Hg or participant placed in Trendelenburg position. For Panels A-H: HR increase over identified baseline of ≥25 beats per minute; SBP reduction >30 mm Hg versus identified baseline; >20 mm Hg drop in SBP and >20 beats per minute rise in HR observed together versus identified baselines; >30 mm Hg drop in orthostatic SBP and >30 beats per minute rise in orthostatic HR observed together. For Panels I-J, any of the following-down dosing criteria if still present 24 hours after dose decrease: HR increase ≥20 beats per minute versus identified baseline; SBP reduction >30 mm Hg versus identified baseline; SBP <100 mm Hg; >30 mm Hg drop in orthostatic SBP and >30 beats per minute rise in orthostatic HR observed together.

    Measured: Up to 28 days

  3. Change From Baseline in Time-weighted Average Across 24 Hours (TWA0-24hrs) cSBP in Male Participants With Mild to Moderate Hypertension Administered Multiple Doses of MK-8150 and Placebo (Panel A/B/C/D)

    cSBP was measured by applanation tonometry of the radial artery, using the SphygmoCor System.

Time-weighted average was obtained as follows: For all pSBP values obtained over the 24-hour observation period, multiply the length of time that the participant spent at each pSBP value by that pSBP value, add these products together, and then divide by duration of the observation period. The length of time spent at an identified pSBP 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. Baseline was Day 1 pre-dose value (determined separately in each period).

    Measured: Pre-dose and 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 16 and 24 hours post dose

  20. Change From Baseline in TWA0-24hrs pDBP Following Day 10 Dose in Male and Female Participants With Resistant Hypertension Administered Multiple Doses of MK-8150 and Placebo (Panel H)

  21. Change From Baseline in TWA0-24hrs AIx in Male Participants With Mild to Moderate Hypertension Administered Multiple Doses of MK-8150 and Placebo (Panel I)

    AIx was measured by applanation tonometry of the radial artery, using the SphygmoCor System. The central pressure waveform was determined from the peripheral pressure waveform by a transfer function. Augmentation index is the percentage of the central pulse pressure attributed to the reflected pulse wave, and is an indirect measure of systemic arterial stiffness. Time-weighted average was obtained as follows: For all AIx values obtained over the 24-hour observation period, multiply the length of time that the participant spent at each AIx value by that AIx value, add these products together, and then divide by duration of the observation period. The length of time spent at an identified AIx 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. AIx was adjusted for HR. Baseline was Day 1 pre-dose value.

    Measured: Pre-dose and 2, 3, 4, 6, 8, 12 and 24 hours post dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MK-8150 in people with Hypertension and Isolated Systolic Hypertension, 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 10 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 25 Sep 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. 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 29 Apr 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 With an Adverse Event (AE) (time frame: Up to 14 days after the last dose (Up to approximately 42 days, excluding pre-dose/screening period)). The study lists 40 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01656408, which also lists 1 linked publication.

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 25 Sep 2018; AzTrials last refreshed its copy on 28 Oct 2026.
