About this study

Official title: A Randomized Double-Blind Placebo-Controlled Single and Multiple Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of MK-8655 in Subjects With Type 2 Diabetes

This study will assess the initial safety, tolerability, pharmacokinetics, and pharmacodynamics of MK-8655, after single and multiple daily oral administrations to participants with Type 2 Diabetes (T2DM). The study will assess the reduction in fasting plasma glucose concentrations from baseline after multiple daily administrations of MK-8655.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • MK-8655Drug

    Participants will receive MK-8655 as a single dose on Day 1. Participants will receive MK-8655, once a day (q.d.), for 14 consecutive days (Day 3 through Day 16). MK-8655 doses may be adjusted downward based on the results of ongoing studies.

  • PlaceboDrug

    Participants will receive Placebo as a single dose on Day 1. Participants will receive Placebo, q.d., for 14 consecutive days (Day 3 through Day 16).

What is being measured

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

  1. Number of Participants With One or More Adverse Events

    An adverse event 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.

    Measured: Up to 14 days after the last dose of study drug (Up to 31 days)

  2. Number of Participants Discontinuing Study Drug Due to an Adverse Event

    An adverse event 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.

    Measured: Up to 17 days

  3. Fasting Plasma Glucose (FPG)

    Blood for fasting plasma glucose (central laboratory) was obtained after at least 10 hours overnight fast.

    Measured: Day 16 (Predose)

Secondary outcomes (3)
  1. True Geometric Mean Plasma Concentrations of MK-8655 After Single and Multiple Drug Doses at 24 Hours Post Dose (C24)

    C24hr was log transformed and analyzed based on a linear mixed effects model containing fixed effects for treatment, day and treatment by day interaction and a random effect for the participant.

    Measured: 24 hours post dose on Days 1, 7, and 14

  2. 24-Hour Weighted Mean Glucose (WMG)

    The WMG provides an integrated assessment of the glycemic exposure over the 24-hour period. To reduce variability of the baseline (before any study drug administration) WMG, participants were domiciled in the test facility at least 36 hours prior to Day 1, where standard meals were provided, and physical activity was monitored. The WMG was derived from multiple glucose values collected during both fasting and post-meal periods. The sample scheme for the 18 point glucose measurements used in this study had many samples taken in the very early morning hours, as well as the first three hours after meals. WMG was calculated as the area under the curve (AUC) of the glucose concentrations divided by the duration of time of samples collected.

    Measured: Day 15: Predose, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, 13, 14, 15, 16, 18, 21, 23 hours post-dose.

  3. Change From Baseline at 2 Hours Oral Glucose Tolerance Test

    Plasma glucose excursion was assessed during an oral glucose tolerance test (oGTT) following a single dose administration of MK-8655 in participants with T2DM.

    Measured: Baseline and 2 hours after dosing on Days 1, 3, and 16

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MK-8655 in people with Type 2 Diabetes, 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 6 inclusion and 12 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 13 Nov 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 13 Nov 2018). 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 One or More Adverse Events (time frame: Up to 14 days after the last dose of study drug (Up to 31 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 13 Nov 2018; AzTrials last refreshed its copy on 8 Nov 2026.
