1 The Effects of Fx-1006A on Transthyretin Stabilization and Clinical Outcome Measures in Patients With Non-V30M Transthyretin Amyloidosis

This is an open-label, multicenter, international study designed to determine TTR stabilization as well as Fx-1006A safety and tolerability, and its effects on clinical outcomes in patients with non-V30M TTR amyloidosis. Strong pre-clinical and clinical evidence support a daily dose of 20 mg of Fx-1006A to be the optimum dose to achieve stabilization of tetrameric TTR in ATTR-PN patients. Since disease presentation is similar between V30M and non-V30M TTR mutations associated with ATTR-PN and Fx-1006A has been shown to stabilize wild-type and V30M TTR in vitro and ex vivo, the present study is being conducted to determine the effects of Fx-1006A on TTR stabilization in ATTR-PN patients with TTR mutations other than V30M. Safety and exploratory efficacy of Fx-1006A administered once daily for 12 months will also be evaluated in this patient population. This is an open-label, multicenter, international study designed to determine TTR stabilization as well as Fx-1006A safety and tolerability, and its effects on clinical outcomes in patients with non-V30M TTR amyloidosis. The study will be conducted in two parts. Part 1 will include a six-week dosing period during which all enrolled patients will receive 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 receiving 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, the patient will be discontinued from the study. During Part 2, clinical outcomes will be measured at Months 6 and 12, based on NIS, Norfolk QOL-DN, mBMI, NCS, HRDB, SF-36, Karnofsky score, and echocardiography; NT-pro-BNP and troponin I levels will be measured at Baseline, Weeks 2 and 6, and Months 3, 6, and 12. Pharmacokinetic measurements will be made using samples collected at Baseline, Week 6, and Months 6 and 12. Safety and tolerability will be assessed throughout the study based on vital signs, physical examinations, ECG, echocardiography, 24-hour Holter monitoring, clinical laboratory tests (hematology, serum chemistry, and urinalysis), and monitoring adverse events and concomitant medication use. Day 1 will be defined as administration of the first dose of study drug. Clinic Visits will be conducted during Screening (Days -30 to -1) and at Baseline (Day 0), and Week 2, and Week 6, and Months 3, 6, and 12 (± 2 weeks of the scheduled date for post-Baseline visits). Monthly telephone contacts (+ 1 week of the scheduled date) will be made during months in which no investigative site visits are scheduled (Months 4, 5, 7, 8, 9, 10, and 11) for assessment of adverse events and concomitant medications. A final telephone contact to assess adverse events and concomitant medication usage will be made 30 days after the last dose of study drug. Patients who discontinue from the study at any time following enrollment 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.

Description: Norfolk QOL-DN: 35-item participant-rated questionnaire used to assess impact of neuropathy on the quality of life of participants diagnosed with ATTR. Scoring was based on 35 questions that yield a TQOL as well as 5 subscale scores: activities of daily living, large fiber neuropathy/physical functioning, small fiber neuropathy, autonomic neuropathy, and symptoms. TQOL= sum of all the items, total possible score range= -2 to 138, where higher score=worse quality of life. This outcome measure was planned to be analyzed only for the reporting arm of participants diagnosed with ATTR.

Time: Baseline (Day 1)

Description: Norfolk QOL-DN: 35-item participant-rated questionnaire used to assess impact of neuropathy on the quality of life of participants diagnosed with ATTR. It was summarized in 5 domains: (1) Activities of daily living (score ranges from 0 to 20, where higher score=worse quality of life); (2) Large fiber neuropathy/physical functioning (score ranges from -2 to 58, where higher score=worse condition); (3) Small fiber neuropathy (score ranges from 0 to 16, where higher score=worse condition); (4) Autonomic neuropathy (score ranges from 0 to 12, where higher score=worse condition) and (5) Symptoms (score ranges from 0 to 32, where higher score=less symptoms of disease). Total possible score range= -2 to 138, where higher score=worse quality of life. This outcome measure was analyzed only for the participants diagnosed with ATTR.

Description: KCCQ was a 23-item participant-completed questionnaire that assessed health status and health-related quality of life (HRQoL) in participants with heart failure. It was quantified in to following 10 summary scores: physical limitation, symptom frequency, symptom severity, and symptom stability, total symptoms, quality of life, social interference, self-efficacy, overall summary and clinical summary. Each summary score was scaled to range from 0 (minimum) to 100 (maximum), with higher scores representing greater disability. Total score ranged from 0 to 100, where higher scores indicated better functioning, fewer symptoms, and better disease specific quality of life.

Measure: Kansas City Cardiomyopathy Questionnaire (KCCQ) Scores

Time: Baseline (Day 1)

Description: ZBI was a 22-item questionnaire designed to evaluate five broad aspects of caregiver burden in terms of personal and role strain associated with caregiving. Five broad aspects were: burden in the relationship, emotional well-being, social and family life, finances, loss of control over one's life.

Time: Baseline (Day 1)

Description: A questionnaire designed to evaluate aspects of caregiver burden in terms of personal and role strain associated with caregiving. Total score of ZBI scale ranges from 0-88 with higher scores indicating increased burden of care. Five subscale scores were also calculated: (1) Burden in the relationship (consist of 6-items, ranging from 0 to 24 where higher scores indicating increased burden in relationship); (2) Emotional well-being (consisting of 7-items, ranging from 0 to 28 where higher scores indicating worse condition; (3) Social and family life (consisting of 4-items, ranging from 0 to 16 where higher scores indicating worse life condition); (4) Finances (consisting of a single item, scored from 0 to 4 where higher scores indicating worse financial condition); and (5) Loss of control over one's life (consisting of 4-items, ranging from 0 to 16 where higher scores indicating worse control over life).
