About this study

Official title: A 12-Week, Phase 2, Randomized, Double-Blind, Placebo Controlled, Dose-Ranging, Parallel Group Study To Evaluate The Efficacy And Safety Of Once Daily Pf-04991532 And Sitagliptin In Adult Patients With Type 2 Diabetes Mellitus Inadequately Controlled On Metformin

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.

Conditions: Diabetes, Type 2
Being tested: Placebo, 150 mg PF-04991532, 450 mg PF-04991532, 750 mg PF-04991532, Sitagliptin 100 mg
Keywords: Phase 2, safety and efficacy study with PF-04991532, Type 2 diabetes
Medical subject headings: Diabetes Mellitus, Type 2

What is being measured

The primary outcome is the main question the study is designed to answer.

Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Week 12
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.
Measured: Baseline, Week 12

Secondary outcomes (6)

Change From Baseline in Fasting Plasma Glucose at Week 1, 2, 4, 8 and 12
Measured: Baseline, Week 1, 2, 4, 8, 12
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.
Measured: Baseline, Week 1, 2, 4, 8
Percentage of Participants Achieving Less Than (<) 6.5% or <7% Glycosylated Hemoglobin (HbA1c) Levels
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.
Measured: Week 12
Change From Baseline in Body Weight at Week 1, 2, 4, 8 and 12
Overweight or obesity increases the risk for developing diabetes. 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.
Measured: Baseline, Week 1, 2, 4, 8, 12
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.
Measured: Week 12
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.
Measured: Week 12

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 150 mg PF-04991532, 450 mg PF-04991532 and 750 mg PF-04991532 in people with Diabetes, Type 2, run by Pfizer at 44 sites in 7 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Aug 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 44 sites in United States, Canada, Mexico, South Korea, Taiwan and 2 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 6 Aug 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Week 12 (time frame: Baseline, Week 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01336738.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Aug 2013.
