Phase I Safety, Pharmacokinetics and Bioavailability Study Comparing Rate and Extent of Absorption of Two Different Forms of Tafamidis (PF-6291826)
A Phase 1 study testing Tafamidis in people with Healthy Volunteers, run by Pfizer at 1 site in Belgium.
Trial summary
2 different formulations and 4 different single doses of tafamidis will be compared. All subjects will receive both formulations and 3 different doses. Subjects will be fasted before taking the drug. After swallowing single dose of tafamidis, tafamidis blood concentrations will be measured periodically for 8 days. Read more about this study

About this study
Official title: A PHASE 1, OPEN-LABEL, RANDOMIZED, THREE-PERIOD, THREE-SEQUENCE, SINGLE-DOSE, CROSSOVER STUDY IN FASTED HEALTHY SUBJECTS, TO ASSESS THE SAFETY, PHARMACOKINETICS AND ORAL BIOAVAILABILITY OF TAFAMIDIS FREE ACID WET-MILLED SUSPENSION DOSES, RELATIVE TO 4 X 20 MG COMMERCIAL TAFAMIDIS MEGLUMINE CAPSULES
2 different formulations and 4 different single doses of tafamidis will be compared. All subjects will receive both formulations and 3 different doses. Subjects will be fasted before taking the drug. After swallowing single dose of tafamidis, tafamidis blood concentrations will be measured periodically for 8 days. After another 16 days, all subjects will repeat the procedure twice, each time with the other formulation/dose.

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 and 4 different single doses of tafamidis will be compared. All subjects will receive both formulations and 3 different doses. Subjects will be fasted before taking the drug. After swallowing single dose of tafamidis, tafamidis blood concentrations will be measured periodically for 8 days. After another 16 days, all subjects will repeat the procedure twice, each time with the other formulation/dose.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Tafamidis in people with Healthy Volunteers, 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 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: finished, as of the sponsor's last update on 11 Feb 2019. 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?
1. Area under the plasma concentration-time profile from time 0 extrapolated to infinite time (AUCinf) (time frame: 0.5, 1, 2, 3, 4, 6, 8, 12, 24, 48, 72, 96, 120, 144 and 168 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 11 Feb 2019.
