What is being measured

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

  1. AUCinf (Area under the plasma concentration-time profile from time zero extrapolated to infinite time) of metformin

    Measured: 0.5, 1.5, 2, 3, 4, 6, 8, 9, 10, 12 and 24 hours after the metformin dose on Day 4

  2. Cmax (Maximum plasma concentration) of metformin

    Measured: 0.5, 1.5, 2, 3, 4, 6, 8, 9, 10, 12 and 24 hours after the metformin dose on Day 4

  3. Clr (Renal clearance) of metformin

    Measured: 0.5, 1.5, 2, 3, 4, 6, 8, 9, 10, 12 and 24 hours after the metformin dose on Day 4

Secondary outcomes (7)
  1. AUClast (Area under the plasma concentration-time profile from time zero to the time of the last quantifiable concentration) of metformin

    Measured: 0.5, 1.5, 2, 3, 4, 6, 8, 9, 10, 12 and 24 hours after the metformin dose on Day 4

  2. t½ (Terminal half-life) of metformin

    Measured: 0.5, 1.5, 2, 3, 4, 6, 8, 9, 10, 12 and 24 hours after the metformin dose on Day 4

  3. Tmax (Time for maximum plasma concentration) of metformin

    Measured: 0.5, 1.5, 2, 3, 4, 6, 8, 9, 10, 12 and 24 hours after the metformin dose on Day 4

  4. Ae24 (Cumulative amount of drug recovered unchanged in urine from time zero to 24 hours postdose) of metformin

    Measured: 0 hours and intervals 0-3, 3-6, 6-9, 9-12 and 12 24 hours after the metformin dose on Day 4

  5. Ae24% (Percent of dose recovered unchanged in urine from time zero to 24 hours postdose) of metformin

    Measured: 0 hours and intervals 0-3, 3-6, 6-9, 9-12 and 12 24 hours after the metformin dose on Day 4

  6. Clr (Renal clearance) over each collection interval for metformin

    Measured: 0 hours and intervals 0-3, 3-6, 6-9, 9-12 and 12 24 hours after the metformin dose on Day 4

  7. CP-690,550 plasma concentration at 2 hours postdose

    Measured: 2 hrs after first CP-690,550 dose on Day 4

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Metformin/CP-690,550 in people with Rheumatoid Arthritis, run by Pfizer at 1 site in Belgium.

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 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: finished, as of the sponsor's last update on 18 Aug 2011. 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 Belgium. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

AUCinf (Area under the plasma concentration-time profile from time zero extrapolated to infinite time) of metformin (time frame: 0.5, 1.5, 2, 3, 4, 6, 8, 9, 10, 12 and 24 hours after the metformin dose on Day 4). The study lists 3 primary outcomes in all. 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 NCT01405118, which also lists 1 linked publication.

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 18 Aug 2011.
