What is being measured

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

  1. Change From Baseline (Day -1) in Mean Daily Glucose at Day 14

Secondary outcomes (18)
  1. Area Under the Curve From Time Zero to 24 Hours Postdose (AUC24) of PF-04991532

    Area under the plasma concentration versus time curve (AUC) from time zero to 24 hours post morning dose

    Measured: 10 (before evening dose), 10.5, 11, 12, 13, 15, 18, and 24 hours after morning dose on Day 1 and Day 14

  5. Minimum Observed Plasma Trough Concentration (Cmin) of PF-04991532

    Measured: Day 14

  6. Time to Reach Maximum Observed Plasma Concentration (Tmax) of PF-04991532 After Morning Dose Administration (Tmax(AM))

    Measured: 0 (predose), 0.5, 1, 2, 3, 4, 6, and 10 hours after morning dose on Day 1 and Day 14

  7. Time to Reach Maximum Observed Plasma Concentration (Tmax) of PF-04991532 After Evening Dose Administration (Tmax(PM))

  8. Apparent Oral Clearance (CL/F) of PF-04991532

    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 pharmacokinetic (PK) modeling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

    Measured: Day 1 and Day 14: 0 (before morning dose), 0.5, 1, 2, 3, 4, 6, 10 (before evening dose), 10.5, 11, 12, 13, 15, 18 and 24 hours after morning dose

  9. Observed Accumulation Ratio of Area Under the Curve From Time Zero to 10 Hours Postdose of PF-04991532 (Rac)

    Area under the curve from time zero to 10 hours postdose of PF-04991532 (AUC10) of Day 14 divided by AUC10 of Day 1

  12. Dose Normalized Maximum Plasma Concentration After Morning Dose Administration (Cmax(AM)(dn)) of PF-04991532

    Maximum Observed Plasma Concentration of PF-04991532 after Morning Dose Administration (Cmax(AM)) divided by dose

    Measured: 0 (before morning dose), 0.5, 1, 2, 3, 4, 6, and 10 hours after morning dose on Day 1 and Day 14

  13. Change From Baseline (Day -2) in Mean Daily Glucose at Day 13

    Mean daily glucose (MDG) was calculated based on the mean of 8 glucose measurements at pre-specified time points throughout the day.

    Measured: Baseline: hours -72, -70, -68, -66, -62, -60, -57, and -54 on Day -2 (Day 1 morning dose was hour 0); Day 13: 0 (before morning dose), 2, 4, 6, 10, 12, 15 and 18 hours after Day 13 morning dose

  14. Change From Baseline in Area Under the Curve of Glucose From Time 2 to 6 Hours Post Morning Dose (Glucose AUC(2-6)) Following Mixed Meal Tolerance Test (MMTT) at Day 14

    Area under the curve of glucose from time 2 to 6 hours post morning dose (Glucose AUC(2-6)) was calculated based on 8 glucose measurements at prespecified time points using the linear trapezoidal method. Nominal times were used in the calculation. Liquid meal was administered 2 hours post morning dose of PF-04991532 for mixed meal tolerance test (MMTT).

    Baseline for fasting triglycerides (TG) was defined as the average of the Day -1 (hour -48), Day 0 (hour -24), and Day 1 pre-dose (hour 0) measurements. Baseline for fasting total cholesterol (TC), cholesterol (high-density lipoprotein (HDL)), and cholesterol (low-density lipoprotein (LDL)) was defined as the Day 1 pre-dose (hour 0) measurement.

    Measured: Baseline: hour -48 on Day -1, hour -24 on Day 0, and hour 0 on Day 1 for TG and Hour 0 (before morning dose) on Day 1 for TC, HDL, and LDL; 48 hours after morning dose on Day 16 for TG and Hour 0 (before morning dose) on Day14 for TC, HDL, and LDL

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PF-04991532 and PF-0499132 in people with Diabetes Mellitus, Type 2, run by Pfizer at 3 sites in 2 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 3 inclusion and 12 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 30 Oct 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States, Japan. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 29 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 (Day -1) in Mean Daily Glucose at Day 14 (time frame: Baseline: hours -46, -44, -42, -40, -38, -36, -33, -and -30 on Day -1 (Day 1 morning dose was hour 0); Day 14: 2, 4, 6, 8, 10, 12, 15, and 18 hours after Day 14 morning dose). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 30 Oct 2013.
