Type 2 Diabetes
Brief summary
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.
Interventions
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.
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).

| Number of Participants Discontinuing Study Drug Due to an Adverse Event | Up to 17 days | 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. |

|---|---|---|
| True Geometric Mean Plasma Concentrations of MK-8655 After Single and Multiple Drug Doses at 24 Hours Post Dose (C24) | 24 hours post dose on Days 1, 7, and 14 | 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. |
| 24-Hour Weighted Mean Glucose (WMG) | Day 15: Predose, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, 13, 14, 15, 16, 18, 21, 23 hours post-dose. | 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. |
| Change From Baseline at 2 Hours Oral Glucose Tolerance Test | Baseline and 2 hours after dosing on Days 1, 3, and 16 | Plasma glucose excursion was assessed during an oral glucose tolerance test (oGTT) following a single dose administration of MK-8655 in participants with T2DM. |

Outcome results
Fasting Plasma Glucose (FPG)
Blood for fasting plasma glucose (central laboratory) was obtained after at least 10 hours overnight fast.

Population: The analysis population was participants who complied with the protocol sufficiently to ensure that these data would likely exhibit the effects of treatment, according to the underlying scientific model. Compliance covered such considerations as exposure to treatment, availability of measurements and absence of major protocol violations.
