Phase 2, safety and efficacy study with PF-04991532, Type 2 diabetes

Brief summary

B2611002 is designed to study how safe and effective an investigational medication (PF-04991532) is in people with Type 2 diabetes. Subjects in the study will receive 1 of 5 treatments for 3 months. One of the treatments will be sitagliptin which is an approved drug, and another treatment will be placebo, which does not contain active ingredient.

The normal range for the HbA1c test is between 4 percent (%) and 5.6%. HbA1c levels between 5.7% and 6.4% indicate increased risk of diabetes and levels of 6.5% or higher indicate diabetes.

HbA1c is a form of hemoglobin which is measured primarily to identify the average plasma glucose concentration over prolonged periods of time. The normal range for the HbA1c test is between 4 percent (%) and 5.6%. HbA1c levels between 5.7% and 6.4% indicate increased risk of diabetes and levels of 6.5% or higher indicate diabetes.

Time frame: Baseline, Week 12

Population: Full analysis set (FAS) included all randomized participants who received at least 1 dose of study medication. Here 'n' signifies participants who were evaluable at specific time point for each treatment arm, respectively.

Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Week 1, 2, 4 and 8

HbA1c is a form of hemoglobin which is measured primarily to identify the average plasma glucose concentration over prolonged periods of time. The normal range for the HbA1c test is between 4% and 5.6%. HbA1c levels between 5.7% and 6.4% indicate increased risk of diabetes and levels of 6.5% or higher indicate diabetes.

Time frame: Baseline, Week 1, 2, 4, 8

Population: FAS included all randomized participants who received at least 1 dose of study medication. Here 'n' signifies participants who were evaluable at specific time point for each treatment arm, respectively.

Percentage of Participants With Greater Than or Equal to (>=) 1% or >= 2% Body Weight Gain From Baseline

Overweight or obesity increases the risk for developing diabetes. Participants with \>= 1% or \>= 2% body weight gain from baseline signifies a higher risk of diabetes.

Time frame: Week 12

Population: FAS included all randomized participants who received at least 1 dose of study medication. Here, N (number of participants analyzed) signify those who were evaluable for this measure.

Percentage of Participants With Greater Than or Equal to (>=) 1% or >= 2% Body Weight Loss From Baseline

The treatment of diabetes has been the recommendation to lose weight. As weight loss progresses and is maintained, an improvement of glycemia may be evidenced by a reduction in HbA1c. Participants with \>= 1% or \>= 2% body weight loss from baseline signifies an improvement of glycemia.

Time frame: Week 12

Population: FAS included all randomized participants who received at least 1 dose of study medication. Here, N (number of participants analyzed) signify those who were evaluable for this measure.
