MK-1006 Single Dose Study in Japanese Type 2 Diabetes Patients (MK-1006-005)

Study Overview
=================
Brief Summary
-----------------
A single rising dose study to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of MK-1006 in Japanese participants with Type 2 Diabetes Mellitus (T2DM). The primary hypothesis of the study is that single doses of MK-1006 will be sufficiently safe and well tolerated, based on the assessment of clinical and laboratory evaluations and adverse experiences, in Japanese participants with T2DM.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants Who Experienced at Least One Adverse Event | An adverse event 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 product. | from the time of the run-in period prior to the first dose of study drug through the end of the poststudy period (up to approximately 31 days) | 
| Number of Participants Who Discontinued Treatment Due to an Adverse Event | An adverse event 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 product. | up to approximately 17 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mean Area Under the Plasma Concentration Curve From Time Zero to Infinity(AUC[0-∞]) After a Single Dose of MK-1006 | AUC(0-∞) was estimated by determining the total area under the curve of the concentration versus time curve extrapolated to infinity. The placebo group was not evaluated for this outcome measure. | Approximately 96 hours for MK-1006 15mg, 30 mg, 45 mg, 60 mg, 60 mg fed (predose up to approximately 96 hours postdose); approximately 120 hours for MK-1006 80 mg, 100 mg, 140 mg, and 170 mg (predose up to 120 hours postdose) | 
| Mean Area Under the Plasma Concentration Curve From Time Zero to 24 Hours (AUC[0-24]) After a Single Dose of MK-1006 | AUC(0 to 24 hours) was estimated by determining the total area under the curve of the concentration versus time curve to 24 hours post dose. The placebo group was not evaluated for this outcome measure. | Approximately 96 hours for MK-1006 15mg, 30 mg, 45 mg, 60 mg, 60 mg fed (predose up to approximately 96 hours postdose); approximately 120 hours for MK-1006 80 mg, 100 mg, 140 mg, and 170 mg (predose up to 120 hours postdose) |

| Apparent Terminal Half-life (T 1/2) After a Single Dose of MK-1006 | The apparent half-life was defined as the time required for the plasma concentration of MK-1006 to decrease 50% in the final stage of its elimination. The means and standard deviations displayed as are the harmonic means and pseudo-standard deviations, respectively. The placebo group was not evaluated for this outcome measure. | Approximately 96 hours for MK-1006 15mg, 30 mg, 45 mg, 60 mg, 60 mg fed (predose up to approximately 96 hours postdose); approximately 120 hours for MK-1006 80 mg, 100 mg, 140 mg, and 170 mg (predose up to 120 hours postdose) | 
| 24-hour Weighted Mean Glucose (WMG) Concentration | Weighted mean glucose concentration was calculated as the 24-hour area under the plasma concentration-time curve divided by 24. | Up to 36 hours |
