About this study
Official title: A Phase 1, Open-label, Randomized, Four-period, Four-sequence, Single-dose, Crossover Study In Healthy Volunteers, To Determine The Relative Bioavailability Of Pf-06291826 61 Mga Tafamidis Free Acid Soft Gelatin Capsules Compared To Commercial 4 × 20 Mg Tafamidis Meglumine Soft Gelatin Capsules Administered Under Fasted And Fed Conditions And The Effect Of Food On The Oral Bioavailability Of Pf-06291826 61 Mga Tafamidis Free Acid Soft Gelatin Capsules
2 different formulations of tafamidis will be compared under both fed and fasted conditions. Subjects will be fasted overnight or fed. After swallowing one of the tafamidis formulations, tafamidis blood concentrations will be measured periodically for 8 days. After 16 days, subjects will take a different formulation in the fed or fasted state or take the same formulation in the opposite feeding condition. This will be repeated, 16 days apart, until all subjects have taken each formulation both fed and fasted.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
2 different formulations of tafamidis will be compared under both fed and fasted conditions. Subjects will be fasted overnight or fed. After swallowing one of the tafamidis formulations, tafamidis blood concentrations will be measured periodically for 8 days. After 16 days, subjects will take a different formulation in the fed or fasted state or take the same formulation in the opposite feeding condition. This will be repeated, 16 days apart, until all subjects have taken each formulation both fed and fasted.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing tafamidis in people with Healthy, 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 2 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 6 Apr 2018. 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?
Area under the concentration-time curve 0-72 hours (AUC72) (time frame: 72 hrs). The study lists 2 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 6 Apr 2018.
