About this study
Open-label, multicenter, international, single-treatment study designed to determine TTR stabilization as well as Fx-1006A safety and tolerability, and its effects on clinical outcomes in patients with V122I or wild-type TTR amyloid cardiomyopathy.
The study will be conducted in two parts. Part 1 will include a six-week dosing period during which all enrolled patients will self-administer oral Fx-1006A 20 mg soft gelatin capsules once daily for six weeks. At Week 6, blood samples will be collected from each patient to determine TTR stabilization. Patients who complete the Week 6 visit will continue taking daily oral Fx 1006A 20 mg for up to a total of 12 months during Part 2 of this study. If it is determined that a patient is not stabilized at Week 6 (based on TTR stabilization data), the patient will be discontinued from the study. Safety and clinical outcomes will be evaluated during Part 2 of this study.

Two whole blood samples for pharmacodynamic assessments (TTR stabilization) and pharmacokinetic assessments (Fx-1006A concentrations as well as calculated steady-state parameters) will be collected at Baseline and Week 6. At Months 6 and 12, two whole blood samples will be collected for pharmacodynamic assessments, and four whole blood samples (two samples per time point) will be collected for pharmacokinetic assessments to be utilized in population pharmacokinetic modeling.
Echocardiography, chest x-ray, cardiac MRI, and 24-hour Holter monitoring will be conducted at Baseline, and Months 6 and 12. Six-minute walk test and quality of life utilizing the Patient Global Assessment, KCCQ, and SF-36 will be assessed at Baseline, and Months 3, 6, and 12. NYHA Classification will be assessed at Baseline, Week 6, and Months 3, 6, and 12. Serum markers of troponin I and T, and NT-pro-BNP levels will be assessed at each study visit.
Safety and tolerability will be assessed throughout the study. Vital signs, 12-lead ECG, blood and urine samples for clinical laboratory tests (serum chemistry, hematology, coagulation panel, and urinalysis), AEs, and concomitant medications (including diuretic usage) will be assessed at each study visit. Abbreviated physical examinations will be conducted at Baseline, Weeks 2 and 6, and Months 3 and 6, and a complete physical examination will be conducted at Month 12.
Clinic visits will be conducted during Screening (Days -30 to -1) and Baseline (Day 0); procedures scheduled for the Baseline visit may be conducted over a period of one week to accommodate patient scheduling. All Baseline procedures must be completed prior to the first self-administered dose on Day 1. Day 1 will be defined as administration of the first dose of study medication, which patients will self-administer at home. During treatment, clinic visits will be conducted at Week 2 (± 2 days), Week 6 (± 1 week), Month 3 (± 1 week), Month 6 (± 2 weeks), and Month 12 (± 2 weeks). Procedures scheduled for the Month 6 and 12 visits may occur over one week during the visit window to accommodate patient scheduling. Monthly telephone contacts (± 1 week of the scheduled date) will be made during months in which no clinical site visits are scheduled (Months 4, 5, 7, 8, 9, 10, and 11) for assessment of AEs and concomitant medications. A final telephone contact to assess AEs and concomitant medication usage will be made 30 days after the last dose of study medication for each patient.
Patients who discontinue from the study at any time will have a final visit performed, including all safety assessments, at the time of discontinuation. Any patient discontinuing after the Month 6 visit will also have all exploratory assessments performed.

What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants With Stabilized Transthyretin (TTR Tetramer) at Week 6
TTR tetramer was assessed using a validated immunoturbidimetric assay. The Fraction of Initial (FOI) is the ratio of the measured TTR tetramer concentration after denaturation to the measured TTR tetramer concentration before denaturation. TTR tetramer stabilization is based on the difference between the on-treatment FOI and the baseline FOI expressed as a percentage of the baseline FOI.
Measured: Week 6

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Open-label, multicenter, international, single-treatment study designed to determine TTR stabilization as well as Fx-1006A safety and tolerability, and its effects on clinical outcomes in patients with V122I or wild-type TTR amyloid cardiomyopathy.
The study will be conducted in two parts. Part 1 will include a six-week dosing period during which all enrolled patients will self-administer oral Fx-1006A 20 mg soft gelatin capsules once daily for six weeks. At Week 6, blood samples will be collected from each patient to determine TTR stabilization. Patients who complete the Week 6 visit will continue taking daily oral Fx 1006A 20 mg for up to a total of 12 months during Part 2 of this study. If it is determined that a patient is not stabilized at Week 6 (based on TTR stabilization data), the patient will be discontinued from the study. Safety and clinical outcomes will be evaluated during Part 2 of this study.
Two whole blood samples for pharmacodynamic assessments (TTR stabilization) and pharmacokinetic assessments (Fx-1006A concentrations as well as calculated steady-state parameters) will be collected at Baseline and Week 6. At Months 6 and 12, two whole blood samples will be collected for pharmacodynamic assessments, and four whole blood samples (two samples per time point) will be collected for pharmacokinetic assessments to be utilized in population pharmacokinetic modeling.

What is this clinical trial studying?
A Phase 2 study testing Fx-1006A in people with Cardiomyopathy, run by Pfizer at 6 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 10 inclusion and 13 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 Jan 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 6 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 18 Dec 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Percentage of Participants With Stabilized Transthyretin (TTR Tetramer) at Week 6 (time frame: Week 6). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00694161, which also lists 2 linked publications.
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 Jan 2013.
