Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence of Adverse Events		From time of enrollment for up to 10 years
Primary	Selected Events of Interest in Patients with Hereditary Transthyretin-mediated (hATTR) Amyloidosis (ATTRv Amyloidosis)	Selected events of interest are defined as hepatic events, cardiovascular events, renal events, ocular events and infusion-related reactions, hypersensitivity, and other events in patients diagnosed with hATTR amyloidosis.	From 1 year prior to enrollment for up to 10 years
Primary	Health Care Provider (HCP)-Assessed Polyneuropathy (PND) Disability Score	PND Scores: Stage 0=No symptoms; Stage I=Sensory disturbances but preserved walking capabilities; Stage II=Impaired walking capacity, but ability to walk without a stick or crutches; Stage IIIA=Walking with help of 1 stick or crutch; Stage IIIB=Walking with the help of 2 sticks or crutches; Stage IV=confined to wheel chair or bedridden.	Up to 11 years
Primary	HCP-Assessed Familial Amyloidotic Polyneuropathy (FAP) Score	FAP Scores: Stage 0=No symptoms; Stage I=Unimpaired ambulation; mostly mild sensory, motor and autonomic neuropathy in the lower limbs; Stage II=Assistance with ambulation required, mostly moderate impairment progression to the lower limbs, upper limbs, and trunk; Stage III=Wheelchair-bound or bedridden; severe sensory, motor, and autonomic involvement of all limbs.	Up to 11 years
Primary	HCP-Assessed Neuropathy Impairment Score (NIS)	NIS : 74 items, assess muscle weakness, reflexes and sensation; scored separately for left, right limbs (37 items for each side). 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) and sensation (touch pressure, pin-prick, vibration, joint position) scored 0 = normal, 1= decreased, or 2 = absent. Total possible NIS score range 0-244, higher score=greater impairment.	Up to 11 years
Primary	HCP-Assessed Cardiomyopathy	Cardiomyopathy will be assessed using New York Heart Association (NYHA) Class: I=No symptoms; II=Symptoms with ordinary physical activity; III=Symptoms with less than ordinary physical activity; IV=Symptoms at rest.	Up to 11 years
Primary	HCP- Assessed Cardiopulmonary Exercise Testing (CPET) Performance		Up to 11 years
Primary	Norfolk Quality of Life - Diabetic Neuropathy (QOL-DN) Total Score	Norfolk-QoL-DN: The Norfolk QOL-DN questionnaire is a standardized 35-item patient-reported outcomes measure that assesses 6 domains: physical function, large-fiber neuropathy, activities of daily living, symptoms, small-fiber neuropathy, and autonomic neuropathy. The total score ranges from -4 points (best possible quality of life) to 136 points (worst possible quality of life).	Up to 11 years
Primary	Kansas City Cardiomyopathy Questionnaire (KCCQ)	The KCCQ is a 23-item self-administered questionnaire developed to independently measure the patient's perception of health status, which includes heart failure symptoms, impact on physical and social function, and how their heart failure impacts their quality of life within a 2-week recall period. The KCCQ quantifies 6 domains (symptoms, physical function, quality of life, social limitation, self-efficacy, and symptom stability) and 2 summary scores (clinical and overall summary [OS] scores).	Up to 11 years
Primary	Rasch-built Overall Disability Scale (R-ODS)	The R-ODS is a 24-item self-administered questionnaire for assessment of the disability a patient experiences. It uses a linearly weighted categorical rating scale that specifically captures domains of activity and social participation limitations in patients.	Up to 11 years
