MeasureTime frameDescription
Change From Baseline in Weighted Mean Daily Glucose (WMDG) at Day 14Prior 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 14Plasma 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.

Change From Baseline in Pre-meal C-Peptide on Day 14Day 14Blood samples for measurement of glucose to permit derivation of pre-meal collections of blood samples for C-peptide at the pre-specified nominal timepoints at predose, 5 and 11 hours on Day 0 (baseline) and Day 14.
Change From Baseline in Pre-meal Insulin on Day 14Day 14Blood samples for measurement of glucose to permit derivation of pre-meal collections of blood samples for insulin at 0, 5 and 11 hours on Day 0 (baseline) and Day 14.

Frequency of Laboratory Test Abnormalities Reported in Any Treatment GroupDay 1 up to Day 14The total number of participants with laboratory test abnormalities (without regard to baseline abnormality) was assessed.
Change From Baseline in Body Weight (kg)Day 1 up to Day 14
Number of Participants With Vital Signs Data Met Criteria of Potential Clinical ConcernDay 1 up to Day 14Vital 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).
Change From Baseline in Fasting Plasma Glucose (FPG) at Day 14Day 14Blood samples for measurement of glucose to permit derivation of pre-meal collections at the pre-specified nominal timepoints of each period: predose (ie, time 0), 1.5, 3, 5, 6.5, 8, 11, 12.5, 14, 16 and 20 hours on Day 0 (baseline) and Day 14; and predose on Days 1 and 15.

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.
Plasma PF-04937319 Apparent Clearance (CL/F) on Day 14Predose, 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.
Plasma PF-04937319 Average Concentration Over the 24-hour Period (Cav) on Day 14Predose, 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.Cav was average concentration over the 24-hour period. The PK parameters were summarized descriptively by treatment as appropriate.

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.

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

Population: Full analysis set defined as all randomized subjects who had taken at least 1 dose of blinded study medication and who had both a baseline and a post-baseline WMDG assessment. Number of participants analyzed was the evaluable participants with a measurement at both baseline and on Day 14.

Plasma PF-04937319 Apparent Clearance (CL/F) on Day 14

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.

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.
