Safety and Efficacy Study of Fx-1006A in Patients With Familial Amyloidosis

Familial Amyloid Polyneuropathy Clinical Trial

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

Status Completed

Clinical Trial 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.
