Arm && Interventions

Group	Intervention	Description
MK-1006 30 mg Twice Daily (Panel F)	MK-1006	After a 2-week run-in/wash-off period, participants received twice-daily doses of 30 mg MK-1006 over a 10-day multiple-dosing period while remaining domiciled in the CRU.
MK-1006 20 mg Once Daily (Panel A)	MK-1006	After a 2-week run-in/wash-off period, participants received single daily doses (q.d.) of 20 mg MK-1006 over a 10-day multiple-dosing period while remaining domiciled in the Clinical Research Unit (CRU).
MK-1006 40 mg Once Daily (Panel B)	MK-1006	After a 2-week run-in/wash-off period, participants received single daily doses of 40 mg MK-1006 over a 10-day multiple-dosing period while remaining domiciled in the CRU.
MK-1006 80 mg Once Daily (Panel C)	MK-1006	After a 2-week run-in/wash-off period, participants received single daily doses of 80 mg MK-1006 over a 10-day multiple-dosing period while remaining domiciled in the CRU.
MK-1006 20 mg Twice Daily (Panel E)	MK-1006	After a 2-week run-in/wash-off period, participants received twice-daily doses (b.i.d.) of 120 mg MK-1006 over a 10-day multiple-dosing period while remaining domiciled in the CRU.
MK-1006 50 mg Twice Daily (Panel G)	MK-1006	After a 2-week run-in/wash-off period, participants received twice-daily doses of 50 mg MK-1006 over a 10-day multiple-dosing period while remaining domiciled in the CRU.
MK-1006 120 mg Once Daily Outpatient (Panel H)	MK-1006	After a 2-week run-in/wash-off period, participants received single daily doses of 120 mg MK-1006 over a 7-day multiple-dosing period while remaining domiciled in the CRU. Participants were then discharged from the CRU and continued daily dosing of MK-1006 for an additional 21 days as outpatients.
MK-1006 50 mg Twice Daily Outpatient (Panel I)	MK-1006	After a 2-week run-in/wash-off period, participants received twice-daily doses of 50 mg MK-1006 over a 7-day multiple-dosing period while remaining domiciled in the CRU. Participants were then discharged from the CRU and continued daily dosing of MK-1006 for an additional 21 days as outpatients.
MK-1006 120 mg Once Daily (Panel D)	MK-1006	After a 2-week run-in/wash-off period, participants received single daily doses of 120 mg MK-1006 over a 10-day multiple-dosing period while remaining domiciled in the CRU.

Primary Outcome Measures

Name	Time	Method
Number of Participants Experiencing Adverse Events (AEs) On Study	From Day 1 through the end of poststudy period (up to Day 25)	An adverse event was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the treatment, whether or not considered related to the study treatment. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the study treatment, was also an adverse event.
Number of Participants Who Discontinued Treatment Due to an AE	From Day 1 through the end of poststudy period (up to Day 25)	An adverse event was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the treatment, whether or not considered related to the study treatment. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the study treatment, was also an adverse event.

Secondary Outcome Measures

Name	Time	Method
Least Squares Mean Change From Baseline in 24-Hour Weighted Mean Glucose (WMG)	Day -1 (pre-dose baseline), Day 1 (First Dosing Day), Day 10 (Last Dosing Day)	Plasma glucose concentration was determined using a glucometer and measured before drug was given to establish a baseline fasting plasma glucose concentration. Plasma glucose concentrations were then measured every \~30 minutes over a 24 hour period after the Day 1 dose (First Dosing Day) and after the Day 10 dose (Last Dosing Day) to obtain a weighted mean average value for Day 1 and for Day 10. Results were expressed as the change from baseline to the Day 1 weighted average (First Dosing Day), and as the change from baseline to the Day 10 weighted average (Last Dosing Day).
