What is being measured

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

  1. Metformin and PD 0332334 area under the curve (AUC) from time 0 to infinity (AUCinf)

    Measured: Days 1 through 7

  2. Metformin and PD 0332334 AUC from 0 to last quantifiable concentration (AUClast)

    Measured: Days 1 through 7

  3. Metformin and PD 0332334 half-life (t1/2)

    Measured: Days 1 through 7

  4. Metformin and PD 0332334 maximum plasma concentration

    Measured: Days 1 through 7

Secondary outcomes (5)
  1. Clinical safety laboratories

    Measured: Days 1 through 7

  2. Incidence, duration and severity of adverse events when study medications administered alone and concurrently

    Measured: Days 1 through 7

  3. Discontinuation due to adverse events when study medications administered alone and concurrently

    Measured: Days 1 through 7

  4. 12-lead ECGs

    Measured: Days 1 through 7

  5. Vital signs

    Measured: Days 1 through 7

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Metformin and PD 0332334 in people with Generalized Anxiety Disorder, run by Pfizer at 1 site in Singapore.

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 2 inclusion and 3 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: stopped early, as of the sponsor's last update on 17 Feb 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Singapore. 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. 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?

The study was stopped early (reason given: Please Detailed Description for termination reason.). Results are not available in the source record.

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?

Metformin and PD 0332334 area under the curve (AUC) from time 0 to infinity (AUCinf) (time frame: Days 1 through 7). The study lists 4 primary outcomes in all. 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 17 Feb 2010.
