What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
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.
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

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Fasting Plasma Glucose (FPG) at Day 14
Time Frame: Day 14
Blood 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.
Day 14
Change From Baseline in Pre-meal C-Peptide on Day 14
Time Frame: Day 14
Blood 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.
Day 14
Change From Baseline in Pre-meal Insulin on Day 14
Time Frame: Day 14
Blood 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.
Day 14

Time Frame: Day 1 up to Day 14
Day 1 up to Day 14
Frequency of Laboratory Test Abnormalities Reported in Any Treatment Group
Time Frame: Day 1 up to Day 14

Day 1 up to Day 14
Number of Participants With Vital Signs Data Met Criteria of Potential Clinical Concern
Time Frame: Day 1 up to Day 14
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).
Day 1 up to Day 14
Number of Participants With Post-baseline Electrocardiograms (ECGs) Data Met Criteria of Potential Clinical Concern
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.

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.

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.
Cav was average concentration over the 24-hour period. The PK parameters were summarized descriptively by treatment as appropriate.
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.

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.
Cmax was highest observed concentration. The PK parameters were summarized descriptively by treatment as appropriate.

Plasma PF-04937319 Lowest Observed Concentration During the 24-hour Period (Cmin) 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.
Cmin lowest observed concentration during the 24-hour period. The PK parameters were summarized descriptively by treatment as appropriate.
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 Time for Cmax (Tmax) 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.
