Filter by: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.
THAOS is a global, multi-center, longitudinal observational survey open to all patients with transthyretin amyloidosis (ATTR), including ATTR-PN (polyneuropathy), ATTR-CM (cardiomyopathy) and wild-type ATTR-CM. It is open-ended with a minimum duration of 10 years. Patients will be followed as long as they are able to participate. The principal aims of this outcome survey are to better understand and characterize the natural history of the disease by studying a large and heterogenous patient population. Survey data may be used to develop new treatment guidelines and recommendations, and to inform and educate clinicians about the management of this disease.
This study will examine whether Fx-1006A is effective in halting the progression of Familial Amyloid Polyneuropathy (FAP). Deposition of TTR amyloid is associated with a variety of human diseases. Deposition of amyloid fibrils of variant TTR (primarily V30M) in peripheral nerve tissue produces the condition called FAP. The prevention of the formation of amyloid by stabilization of the TTR native state should constitute an effective therapy for amyloid diseases. Therapeutic intervention with a TTR stabilizer drug, such as Fx-1006A, is hypothesized to stop progression of the disease in FAP patients. FAP is a uniformly fatal disease and Fx-1006A is intended to halt the relentless neurological deterioration FAP patients experience. This Phase 2/3 study will enroll early to mid-stage FAP patients in order to interrupt and stabilize the disease at a point in time where progression of motor and autonomic dysfunction can be maximally effected. Male and female patients with FAP with documented V30M TTR mutation will receive Fx-1006A or placebo once daily for a period of eighteen (18) months.
