About this study
Official title: A Double Blind, 3rd Party Open, Placebo Controlled, Dose Escalating, Parallel Study To Investigate The Safety, Toleration And Pharmacokinetics Of Multiple Oral Doses Of PF-04634817 In Healthy Volunteers
The goals of this study are to evaluate the safety and tolerability of multiple ascending doses of PF-04634817 administered orally to healthy adult subjects. In additional, the plasma and urinary pharmacokinetics of multiple ascending doses of PF-04634817 administered orally to healthy adult subjects will be evaluated. Finally, the effect of multiple doses of PF-04634817 on circulating monocytes will be explored.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing PF-04634817 in people with Healthy, 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 2 inclusion and 5 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 8 Jun 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 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?
Adverse events, supine and standing vital sign measurements, 12-lead ECGs, blood and urine safety tests. (time frame: 14 days). The study lists 5 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 8 Jun 2011; AzTrials last refreshed its copy on 31 Oct 2026.
