Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Weighted Mean Daily Glucose (WMDG) at Day 14
Time Frame: Prior to morning dose (Hour 0) and at 1.5, 3, 5, 6.5, 8, 11, 12.5, 14, 16, 20, and 24 hours post morning dose on Days 0 (baseline) and Day 14
Plasma glucose concentration was determined predose (Hour 0) and at 1.5, 3, 5, 6.5, 8, 11, 12.5, 14, 16, 20, and 24 hours postdose on Days 0 (baseline) and 14. WMDG was calculated as the area under the curve (AUC) of the 12-point plasma glucose concentration-time profile divided by 24 hours.

Vital signs included blood pressure (BP; supine, sitting and standing) and pulse rate. Vital signs criteria of potential clinical concern were 1), BP: sitting systolic BP (SBP) greater than or equal to (>=) 30 millimeters of mercury (mm Hg) change from baseline, sitting SBP =<20 mmHg change from baseline, supine/sitting/standing SBP less than (<) 90 mm Hg; sitting diastolic BP (DBP) >=20 mm Hg change from baseline, sitting SBP =<20 mmHg change from baseline, supine/sitting/standing DBP <50 mm Hg; 2), pulse rate (supine): <40 or greater than (>) 120 beats per minute (bpm).

Time Frame: Day 1 up to Day 14
ECG criteria of potential clinical concern were 1), PR interval: >=300 milliseconds (msec); >=25% increase when baseline >200 msec; or increase >=50% when baseline <=200 msec; 2), QRS interval: >=140 msec; >=50% increase from baseline; 3), QTc interval using Fridericia's formula (QTcF interval): absolute value >=450 - <480 msec, >=480-<500 msec, >500 msec; absolute change 30 - <60, >=60 msec.
Day 1 up to Day 14
Plasma PF-04937319 Area Under the Concentration Time Curve From Time 0 to 24 Hours (AUC24) of PF-04937319 at Day 14
Time Frame: Predose, 1.5, 3, 5, 6.5, 8, 11, 12.5, and 14 hours on Days 0 and 14; and predose on Days 7 and 15.
The PK parameters were summarized descriptively by treatment as appropriate. Two (2) PK parameters specified in the protocol and SAP were not reported: AUClast was not reported since it was the same as AUC24 in this study, and apparent volume of distribution (Vz/F) was not reported since the log-linear terminal phase of the concentration-time profiles was not consistently well characterized in the 24-hour sampling period.
Predose, 1.5, 3, 5, 6.5, 8, 11, 12.5, and 14 hours on Days 0 and 14; and predose on Days 7 and 15.
Plasma PF-04937319 Apparent Clearance (CL/F) on Day 14
Time Frame: Predose, 1.5, 3, 5, 6.5, 8, 11, 12.5, and 14 hours on Days 0 and 14; and predose on Days 7 and 15.
The PK parameters were summarized descriptively by treatment as appropriate. Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Clearance was estimated from population PK modeling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

Predose, 1.5, 3, 5, 6.5, 8, 11, 12.5, and 14 hours on Days 0 and 14; and predose on Days 7 and 15.
