A Trial To Assess The Safety, Tolerability, Pharmacokinetics, And Pharmacodynamics Of Single Doses Of PF-04937319 In Subjects With Type 2 Diabetes Mellitus

An AE was any untoward medical occurrence in a participant who received study medication without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study medication and up to 10 days after last dose that were absent before treatment or that worsened relative to pretreatment state.

Area under the plasma concentration-time curve from zero to the last measured concentration (AUClast).

Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug.

Plasma decay half-life (t1/2) is the time measured for the plasma concentration to decrease by one half.

AUCinf is the area under the plasma concentration versus time curve from time zero to extrapolated infinite time.

Ratio of area under the plasma C-peptide concentration-time curve from time 2 to 6 hrs (in terms of nanogram*deciliter*hour [ng*dL*hour]) to area under the plasma glucose concentration-time curve from time 2 to 6 hrs (in terms of milligram*milliliter*hour [mg*mL*hour]) was calculated. Linear trapezoidal method was used to compute AUC. The change in ratio from baseline (Day -1) was calculated at Day 1.

Percent change from baseline in post-prandial area under the plasma glucose concentration-time curve as determined by standardized MMTT. Linear trapezoidal method was used to compute AUC. Baseline value was the AUC (2-6) calculated on Day -1.

Percent change from baseline in post-prandial area under the plasma insulin concentration-time curve as determined by standardized MMTT. Linear trapezoidal method was used to compute AUC. Baseline value was the AUC (2-6) calculated on Day -1.

Percent change from baseline in post-prandial area under the plasma C-peptide concentration-time curve as determined by standardized MMTT. Linear trapezoidal method was used to compute AUC. Baseline value was the AUC (2-6) calculated on Day -1.

Ratio of insulin delta C30 (in terms of milliunits*deciliter [mU*dL]) to glucose delta C30 (in terms of milligram*liter [mg*liter]) was calculated. The change in ratio from baseline (Day -1) was calculated at Day 1.

Ratio of C-peptide Delta C30 (in terms of nanogram*deciliter [ng*dL]) to glucose delta C30 (in terms of milligram*milliliter [mg*mL]) was calculated. The change in ratio from baseline (Day -1) was calculated at Day 1.

Ratio of area under the plasma insulin concentration-time curve from time 2 to 6 hrs (in terms of milliunit*deciliter*hour [mU*dL*hour]) to area under the plasma glucose concentration-time curve from time 2 to 6 hrs (in terms of milligram*liter*hour [mg*liter*hour]) was calculated. Linear trapezoidal method was used to compute AUC. The change in ratio from baseline (Day -1) was calculated at Day 1.
