- Ages 65 to 85 years
- All sexes
- Healthy volunteers accepted
- Older adult
Who may be able to join
- Healthy male and/or female subjects between the ages of 65 and 85 years, inclusive. Ideally at least 25% of the subjects enrolled in each cohort will be 75 years of age and above at Screening. Subjects must be healthy as determined by the investigator based on a detailed medical history, full physical examination (including blood pressure and pulse rate measurement), 12-lead ECG and clinical laboratory test results. Subjects with mild, chronic, stable disease and on stable medication may be enrolled if deemed medically prudent by the investigator.

- Evidence of a personally signed and dated informed consent document indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of the study.
Who cannot join
- Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing).
- Any condition possibly affecting drug absorption (eg, gastrectomy).
- Evidence of gout/hyperuricemia, measured sUA >8 mg/dL at screening.
- Experienced an episode of nephrolithiasis or ureterolithiasis.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing PF-06743649 in people with Healthy Elderly, run by Pfizer at 2 sites 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 3 inclusion and 4 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 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites 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 was stopped early (reason given: The study was prematurely terminated on 17th December 2014 due to safety concerns.). 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?
Maximum Observed Plasma Concentration (Cmax) (time frame: up to 14 days). The study lists 7 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 Mar 2015; AzTrials last refreshed its copy on 6 Nov 2026.
