The physical examination (including weight and vital signs) and the relevant end of study clinical laboratory tests (alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, gamma glutamyl transferase, creatinine, total bilirubin, international normalized ratio, troponin I, troponin T, and amino-terminal B-type natriuretic peptide) from Protocol Fx1B-201 will be used for Protocol Fx1B-303. If more than 30 days has elapsed between the final study visit of Protocol Fx1B-201 and Day 0 of Protocol Fx1B-303, an abbreviated physical examination (including weight and vital signs) and clinical laboratory assessments must be performed on Day 0.
Eligible patients will begin once-daily dosing with 20 mg Fx-1006A at home on Day 1 (i.e., first dose) and will return to the clinical unit for study visits every 6 months.
Adverse events (AEs) and concomitant medication use will be collected at each 6-month visit to the clinical unit. Blood draws for clinical safety laboratory tests and abbreviated physical examinations (including weight and vital signs) will also be performed at each 6-month clinic visit. ECGs will be performed every 12 months on an annual basis. A telephone call will be made at 3-month intervals between clinic visits to assess safety and use of concomitant medications.
For the evaluation of efficacy, the Patient Global Assessment, NYHA classification, KCCQ, 6-minute walk test, and efficacy-related clinical laboratory tests (serum levels of troponin T, troponin I, and NT-pro-BNP) will be determined every 6 months. In addition, echocardiograms will be performed every 12 months on an annual basis.
An end of study visit including all safety and efficacy assessments will occur upon patient completion of the study, premature withdrawal (for any reason), or in the event of program discontinuation by the Sponsor.

Number of Participants Classified on the Basis of New York Heart Association (NYHA) Classification at Baseline
NYHA classified participants in 4 classes. Class I included participants with cardiac disease without limitations of physical activity. Ordinary physical activity did not cause undue fatigue, palpitation, dyspnea, or anginal pain. Class II included participants with cardiac disease with slight limitation of physical activity. They were comfortable at rest. Ordinary physical activity resulted in fatigue, palpitation, dyspnea, or anginal pain. Class III included participants with cardiac disease with marked limitation of physical activity. They were comfortable at rest. Less than ordinary physical activity caused fatigue, palpitation, dyspnea, or anginal pain. Class IV included participants with cardiac disease with the inability to carry on any physical activity without discomfort. Symptoms of cardiac insufficiency or of the anginal syndrome might be present even at rest. If any physical activity was undertaken, discomfort was increased.

Change From Baseline in Dyspnea and Fatigue Scores During 6 Minute Walk Test (6MWT) at Month 12
6MWT is a sub-maximal exercise test used to assess aerobic capacity and endurance. Participants were asked to walk as far as possible for 6 minutes at a pace that was comfortable to them, and were permitted to slow down, to stop, and to rest as necessary. Dyspnea: participants were asked to rate the difficulty of their breathing, pre-walk and post-walk at each visit, on a scale of range 0 (no breathlessness at all) to 10 (maximum breathlessness). Higher scores indicated more severity. Fatigue: participants were asked to rate the how tired they felt, pre-walk and post-walk at each visit, on a scale of range 0 (not at all) to 10 (maximal) Higher scores indicated more fatigue. At each visit, scores for pre-walk test, post-walk test and within visit difference (difference from post-walk to pre-walk) were evaluated. Change from baseline was calculated for each pre-walk test, post-walk test and within visit difference at Month 12.

Change From Baseline in Kansas City Cardiomyopathy Questionnaire (KCCQ) Summary Score at Month 12
KCCQ is a 23-item participant-completed questionnaire that assesses health status and health-related quality of life in participants with heart failure. Eight domain scores were calculated for the KCCQ: physical limitation, social limitation, quality of life, self-efficacy, symptom stability, symptom frequency, symptom burden, and total symptoms (calculated as the mean of symptom frequency and symptom burden scores). Two summary scores were calculated: clinical summary (calculated as mean of physical limitation and total symptom scores) and overall summary (calculated as mean of physical limitation, social limitation, total symptoms, and quality of life scores). Each domain and both summary scores were scaled to range from 0 (worse health status) to 100 (best health status); higher scores represented better health status.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Open-label Safety and Efficacy Evaluation of Fx-1006a in Patients with V122i Or Wild-type Transthyretin (ttr) Amyloid Cardiomyopathy.
Patients who successfully complete Fx1B-201 will report to the clinical unit on Day 0 to sign the informed consent form and determine eligibility for Protocol Fx1B-303. In addition, on Day 0, patients will have their entrance criteria reviewed, and medical histories and demographic characteristics obtained.
The physical examination (including weight and vital signs) and the relevant end of study clinical laboratory tests (alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, gamma glutamyl transferase, creatinine, total bilirubin, international normalized ratio, troponin I, troponin T, and amino-terminal B-type natriuretic peptide) from Protocol Fx1B-201 will be used for Protocol Fx1B-303. If more than 30 days has elapsed between the final study visit of Protocol Fx1B-201 and Day 0 of Protocol Fx1B-303, an abbreviated physical examination (including weight and vital signs) and clinical laboratory assessments must be performed on Day 0.
Eligible patients will begin once-daily dosing with 20 mg Fx-1006A at home on Day 1 (i.e., first dose) and will return to the clinical unit for study visits every 6 months.
Adverse events (AEs) and concomitant medication use will be collected at each 6-month visit to the clinical unit. Blood draws for clinical safety laboratory tests and abbreviated physical examinations (including weight and vital signs) will also be performed at each 6-month clinic visit. ECGs will be performed every 12 months on an annual basis. A telephone call will be made at 3-month intervals between clinic visits to assess safety and use of concomitant medications.
For the evaluation of efficacy, the Patient Global Assessment, NYHA classification, KCCQ, 6-minute walk test, and efficacy-related clinical laboratory tests (serum levels of troponin T, troponin I, and NT-pro-BNP) will be determined every 6 months. In addition, echocardiograms will be performed every 12 months on an annual basis.
An end of study visit including all safety and efficacy assessments will occur upon patient completion of the study, premature withdrawal (for any reason), or in the event of program discontinuation by the Sponsor.

Number of Participants Classified on the Basis of New York Heart Association (NYHA) Classification at Baseline
Time frame: Baseline
NYHA classified participants in 4 classes. Class I included participants with cardiac disease without limitations of physical activity. Ordinary physical activity did not cause undue fatigue, palpitation, dyspnea, or anginal pain. Class II included participants with cardiac disease with slight limitation of physical activity. They were comfortable at rest. Ordinary physical activity resulted in fatigue, palpitation, dyspnea, or anginal pain. Class III included participants with cardiac disease with marked limitation of physical activity. They were comfortable at rest. Less than ordinary physical activity caused fatigue, palpitation, dyspnea, or anginal pain. Class IV included participants with cardiac disease with the inability to carry on any physical activity without discomfort. Symptoms of cardiac insufficiency or of the anginal syndrome might be present even at rest. If any physical activity was undertaken, discomfort was increased.

Change From Baseline in Dyspnea and Fatigue Scores During 6 Minute Walk Test (6MWT) at Month 12
Time frame: Baseline, Month 12
6MWT is a sub-maximal exercise test used to assess aerobic capacity and endurance. Participants were asked to walk as far as possible for 6 minutes at a pace that was comfortable to them, and were permitted to slow down, to stop, and to rest as necessary. Dyspnea: participants were asked to rate the difficulty of their breathing, pre-walk and post-walk at each visit, on a scale of range 0 (no breathlessness at all) to 10 (maximum breathlessness). Higher scores indicated more severity. Fatigue: participants were asked to rate the how tired they felt, pre-walk and post-walk at each visit, on a scale of range 0 (not at all) to 10 (maximal) Higher scores indicated more fatigue. At each visit, scores for pre-walk test, post-walk test and within visit difference (difference from post-walk to pre-walk) were evaluated. Change from baseline was calculated for each pre-walk test, post-walk test and within visit difference at Month 12.

What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
