Description: SF-12 was a patient reported outcome survey that represented overall health status by measuring 8 health-related aspects of an individual: Body pain, general mental health, perception of general health, physical functioning, role limitations caused by mental condition, role limitations caused by a physical condition, social functioning, and vitality. The score range for each of the 8 health aspects was from 0 (poor health) to 100 (better health), higher scores indicating good health condition. Responses on the SF-12 were also used to calculate 2 summary scores: Physical component score (PCS) and mental component score (MCS). The score range for each of these 2 summary scores was from 0 (poor health) to 100 (better health), where 100 indicated good health condition.

Each subscale comprised of 7 items and the participant responds as to how each item applies to him/her over the past week prior to baseline visit, on 4-point response scale. Separate scores were calculated for anxiety and depression with score ranges from 0 (no presence of anxiety or depression) to 3 (severe feeling of anxiety or depression). Total score range was from 0 to 21 for each subscale; higher score indicating greater severity of anxiety and depression symptoms.

2 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: NCS: quantitative measures of peripheral nerve dysfunction consists of 5 attributes: peroneal nerve (PN) motor distal latency, PN compound muscle action potential, PN motor conduction velocity, tibial nerve distal motor latency, sural nerve sensory nerve action potential. Normal deviates (Z-score) summated into composite score (higher score=worsened nerve fiber function). Z-score is the defined position of the result in normal probability distribution with a mean of 0 and standard deviation (std) of 1 and describes how far a score is (in std) from the mean.

Description: HRDB test was used to evaluate the cardio-vagal response. Participant took a series of 8 deep breaths and average heart rate difference was measured and compared to normative data. The main factor affecting HRDB is age, with older patients showing less heart rate variability. R-R (time between two consecutive R waves in the electrocardiogram) response to deep breathing was reported as the normal deviates (Z-score), the defined position of the result in normal probability distribution with a mean of 0 and standard deviation (std) of 1 and describes how far a score is (in std) from the mean.

Measure: Change From Baseline in Left Ventricular Mass (LVM) at Month 6, Month 12

Time: Baseline, Month 6, Month 12

Description: Doppler echocardiography was a procedure which used ultrasound technology to examine the heart. IVRT is the time between the closure of the aortic valve and the opening of the mitral valve. Mitral deceleration time (MDT) was the time taken from the maximum E point wave to baseline. E wave arises due to early diastolic filling.
