Primary Outcome Measures
Val30Met Group: Neuropathy Impairment Score Lower Limb (NIS-LL) Score at Baseline
NIS-LL: a subscale (of 37-item NIS questionnaire) that provided a total neuropathic deficit score for the lower limbs. It assess muscle weakness, reflexes, sensation; scored separately for left, right limbs. Components of muscle weakness (hip and knee flexion, hip and knee extension, ankle dorsiflexors, ankle plantar flexors, toe extensors, toe flexors) scored on scale 0 (normal) to 4 (paralysis), higher score=greater weakness. Components of reflexes (quadriceps femoris, triceps surae); sensation (touch pressure, pin-prick, vibration, joint position) scored 0=normal, 1=decreased, or 2=absent. Total possible NIS-LL score range 0-88, high score=more impairment.

Brief Summary
This is a Phase 3, open-label study designed to obtain additional long-term safety and efficacy data for oral tafamidis (20 mg soft gelatin capsule) administered once daily (QD). In addition, this study continued to provide tafamidis to Val30Met subjects who had completed Protocol Fx-006 (a 1-year, open-label extension study to Protocol Fx-005 which was a randomized, double-blind, placebo-controlled, 18-month study to evaluate the safety and efficacy of tafamidis) or non-Val30Met subjects who had completed Protocol Fx1A-201 (a Phase 2, open-label study to evaluate TTR stabilization, safety, and tolerability of tafamidis) for up to 10 years or until subjects had access to tafamidis for ATTR-PN via prescription. Upon regulatory approval for the treatment of ATTR-PN in their respective country and access to prescription tafamidis, subjects may have been withdrawn from the study. Such subjects were considered study completers.

Title
Val30Met Group: Neuropathy Impairment Score Lower Limb (NIS-LL) Score at Baseline
Description
NIS-LL: a subscale (of 37-item NIS questionnaire) that provided a total neuropathic deficit score for the lower limbs. It assess muscle weakness, reflexes, sensation; scored separately for left, right limbs. Components of muscle weakness (hip and knee flexion, hip and knee extension, ankle dorsiflexors, ankle plantar flexors, toe extensors, toe flexors) scored on scale 0 (normal) to 4 (paralysis), higher score=greater weakness. Components of reflexes (quadriceps femoris, triceps surae); sensation (touch pressure, pin-prick, vibration, joint position) scored 0=normal, 1=decreased, or 2=absent. Total possible NIS-LL score range 0-88, high score=more impairment.

Val30Met Group: NIS-LL Subscales Scores: Muscle Weakness (MW), MW-Hip, MW-Knee, MW-Ankle, MW-Toe, NIS-LL Reflexes, NIS-LL Sensory at Baseline
Description
NIS-LL: a subscale (of 37-item NIS questionnaire) that provided a total neuropathic deficit score for the lower limbs. It assess muscle weakness, reflexes, sensation; scored separately for left, right limbs with a total possible NIS-LL score range of 0 to 88, higher score=greater impairment. Components of muscle weakness (hip and knee flexion, hip and knee extension, ankle dorsiflexors, ankle plantar flexors, toe extensors, toe flexors) scored on scale 0 (normal) to 4 (paralysis), higher score=greater weakness. Components of reflexes (quadriceps femoris, triceps surae); sensation (touch pressure, pin-prick, vibration, joint position) scored 0=normal, 1=decreased, or 2=absent. NIS-LL Muscle Weakness score range is 0 to 64, high score=more impairment. NIS-LL Sensation score range is 0 to 16, high score=more impairment. NIS-LL Reflexes score range is 0 to 8, high score=more impairment.
