Being tested
Period 1, Period 2
Keywords
DDI, Healthy Volunteers

What participants receive

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

  • Period 1Drug

    Subjects will receive a single 45 mg dose of PF-00299804 on Day 1 of Period 1.

  • Period 2Drug

    Subjects will receive a single 30 mg tablet of paroxetine once daily for 3 days (Days 1 to 3). Then, subjects will be co-administered a 45 mg single dose of PF-00299804 plus a single dose of 30 mg paroxetine on Day 4. Single 30 mg doses of paroxetine will be administered once daily for 6 days (Days 5-10).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Period 1 and Period 2 in people with Healthy Volunteers, run by Pfizer at 1 site in United States.

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 5 inclusion and 9 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 22 Jun 2012. 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 United States. 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?

Plasma AUCinf of PF-00299804 when given alone in healthy volunteers who are extensive CYP2D6 metabolizers (time frame: 8 weeks). The study lists 6 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 22 Jun 2012.
