What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PF-03654764Drug

    5mg orally once daily for 10 days. After satisfactory review of the available safety, toleration and PK data, progression to the next dose will occur if the last dose was well tolerated. If the previous dose was not well tolerated, after review of the safety data, and discussion between the Pfizer Study Team and the Investigator, the same dose may be given again, a lower dose within the tolerated dose range may be given, or the study may be stopped. The dose increments will be based on emerging safety and toleration data, as well as plasma exposure estimates and forward predictions of PK. Nominal administered doses will not exceed 24 mg per day.

  • placeboDrug

What is being measured

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

  1. safety & toleration: Adverse events, vital signs, 12 lead ECG, blood and urine safety tests, suicidality assessment using the Suicidality Tracking Scale (STS) and physical examination.

    Measured: 10 days

Secondary outcomes (2)
  1. Plasma pharmacokinetics: Cmax, Tmax, AUCtau, t½, AUCtau (Day 10)/AUCtau (Day 1), CL/F

    Measured: 10 days

  2. Urine pharmacokinetics: Ae24 & Ae24% (for once daily doses) or Ae12 & Ae12% (for twice daily dose) on Day 10, CLR

    Measured: 10 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PF-03654764 in people with Healthy, 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 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 16 Dec 2009. 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 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?

safety & toleration: Adverse events, vital signs, 12 lead ECG, blood and urine safety tests, suicidality assessment using the Suicidality Tracking Scale (STS) and physical examination. (time frame: 10 days). 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 16 Dec 2009.
