Title: Safety and Efficacy of Orally Administered Fx-1006A in Patients With Familial Amyloid Polyneuropathy (FAP): A Randomized, Double-blind, Placebo-controlled Study
Brief Summary: 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.

10. Co-morbidity anticipated to limit survival to less than 18 months.
11. Patient received an investigational drug/device and/or participated in another clinical investigational study within 60 days before Baseline.

* Received an investigational agent, other than tafamidis or diflunisal, within 30 days prior to first dose study drug administration;
* Prior liver transplant;
* Poor cardiac function;
* Considered unfit for the study by the Principal Investigator;
* Employee or family member of the sponsor or the clinical study site personnel.
C: Inclusion Criteria:

Exclusion Criteria:

* Had a prior liver transplant or is planned to undergo liver transplant during the study period;
* Has untreated hypo- or hyperthyroidism;
* Has known human immunodeficiency virus (HIV) infection;
* Had a malignancy within 2 years, except for basal or squamous cell carcinoma of the skin or carcinoma in situ of the cervix that has been successfully treated;
* Recently received an investigational agent or device
* Is currently taking diflunisal, tafamidis, doxycycline, or tauroursodeoxycholic acid
D: Inclusion Criteria:

* Patient has amyloid documented by biopsy (in accordance with institutional site standard of care).
* Patient has documentation of one of the following targeted TTR mutations: Ser77Tyr, Thr60Ala, Tyr114Cys, Leu58His, Glu89Gln, Ser77Phe, Thr49Ala, Ile107Val, Val30Ala, Gly47Ala, Gly47Glu, Leu55Arg, Lys70Asn, Ile84Thr, Ile107Met. Patients with mutations other than those listed may be enrolled only after approval by the Sponsor.
* Patient has peripheral and/or autonomic neuropathy and/or cardiomyopathy with a Karnofsky Performance Status ≥ 50.
* Patient is aged ≥18 to 75 years, inclusive.
* If female, patient is post-menopausal, surgically sterilized, or willing to use two acceptable methods of birth control (i.e., a hormonal contraceptive, intra-uterine device, diaphragm with spermicide, condom with spermicide) throughout the study and for 3 months from the end of the study. (A condom alone is not considered an acceptable method of birth control.) If male with a female partner of childbearing potential, willing to use two acceptable methods of birth control for the duration of the study. For both females and males, acceptable birth control must be used for at least 3 months after the last dose of study medication.
* Patient is, in the opinion of the investigator, willing and able to comply with the study medication regimen and all other study requirements.

Exclusion Criteria:

* Chronic use of non-steroidal anti-inflammatory drugs (NSAIDs), defined as greater than 3-4 times/month (ibuprofen and nimesulide will be permitted).

* Patient has liver function test abnormalities: alanine transaminases (ALT) and/or aspartate transaminases (AST) \> 2 times upper limit of normal (ULN) that in the medical judgment of the investigator are due to reduced liver function or active liver disease.
