Phase 2 Study To Evaluate Safety And Efficacy Of Investigational Drug - PF04937319 In Patients With Type 2 Diabetes

HbA1c is a form of hemoglobin which is measured primarily to identify the average glycemic control over prolonged periods of time. The normal range for the HbA1c test, was identified as less than (\<) 6.5 percent (%) by the study-specific central laboratory used. Change from baseline in percentage of HbA1c in participants were reported.

Data for Week 1 had not been reported because as per protocol it was not intended to be collected.

HbA1c is a form of hemoglobin which is measured primarily to identify the average glycemic control over prolonged periods of time. The normal range for the HbA1c test, was identified as \<6.5 percent by the study-specific central laboratory used. Change from baseline in percentage of HbA1c in participants were reported.

Time frame: Baseline(Day 1), Week 2, 4, 8

Population: FAS: All randomized participants who received at least 1 dose of study treatment. Here, 'N' signifies participants for whom data was summarized for this measure and 'n' signifies participants who were evaluable at given time points for each group. Data for Week 2 had not been reported because as per protocol it was not intended to be collected.

A hypoglycemic event (HAE) was identified by characteristic symptoms or blood glucose levels. Median number of events per participant was reported

Time frame: Baseline (Day 1) up to Week 14

Population: Safety analysis set included all randomized participants who received at least 1 dose of study treatment. Here, 'N' signifies participants for whom data was collected for this measure.

Participants who met the criteria for increase or decrease in vital signs data were reported. Criteria for increase or decrease from baseline vital signs data: sitting systolic blood pressure (BP) of \>=30 millimeter of mercury (mmHg); sitting diastolic BP of \>=20 mmHg and pulse rate was based on investigator's discretion.

Time frame: Baseline (Day 1) up to Week 14

Population: Safety analysis set included all randomized participants who received at least 1 dose of study treatment. Here, 'N' signifies participants for whom data was collected for this measure.

An AE was any untoward medical occurrence in a participant who received study drug 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 drug and up to 14 days after last dose that were absent before treatment or that worsened relative to pretreatment state. AEs included both serious and non-serious adverse events.

Time frame: Baseline (Day 1) up to 14 days after last dose (up to 101 days)

Population: Safety analysis set included all randomized participants who received at least 1 dose of study treatment.

HbA1c is a form of hemoglobin which is measured primarily to identify the average glycemic control over prolonged periods of time. The normal range for the HbA1c test, was identified as \<6.5 percent by the study-specific central laboratory used and data are presented in categories of \<6.5 percent and \<7 percent.

Population: FAS: All randomized participants who received at least 1 dose of study treatment. Here, 'N' signifies participants for whom data was summarized for this measure.

A hypoglycemic event (HAE) was identified by characteristic symptoms or blood glucose levels. HAE is defined as 1 of the given definitions: Characteristic symptoms of HAE with no home glucose monitoring performed where clinical picture included prompt resolution with food intake, subcutaneous glucagon, or intravenous glucose; or characteristic symptoms of HAE with home glucose monitoring measurement =\< 70 milligram per deciliter (mg/dL) using ACCU-CHEK plasma-referenced home glucometers or =\<74 mg/dL using International Federation of Clinical Chemistry (IFCC) referenced ACCU-CHEK or central laboratory glucometers; or any laboratory glucose value, meeting the following criterion with or without accompanying symptoms: =\<49 mg/dL using ACCU-CHEK plasma-referenced home glucometers or =\<53 mg/dL using IFCC referenced ACCU-CHEK or central laboratory glucometers.
