2. Females must be non-pregnant and non-lactating, and either surgically sterile or
post-menopausal or abstinent

3. Males must be surgically sterile or, abstinent or, if engaged in sexual relations with
a woman of child-bearing potential, the subject or the subject's non-pregnant female
partner must be using a highly effective contraceptive method

4. Diagnosis of hereditary transthyretin-mediated polyneuropathy as defined by meeting
all 3 of the following:

- Stage 1 or Stage 2 Familial Amyloid Polyneuropathy (FAP) or Coutinho Stage

- Documented genetic mutation in the TTR gene

- Symptoms and signs consistent with neuropathy associated with transthyretin
amyloidosis, including NIS = 10 and = 130
Minimum age
18 Years
Maximum age
82 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Clinically-significant (CS) abnormalities in medical history, screening laboratory
results, physical or physical examination that would render a subject unsuitable for
inclusion, including but not limited to abnormal safety labs

2. Karnofsky performance status = 50

3. Other causes of sensorimotor or autonomic neuropathy (e.g., autoimmune disease),
including uncontrolled diabetes

4. Prior liver transplant or anticipated liver transplant within 1-yr of Screening

5. New York Heart Association (NYHA) functional classification of = 3

6. Acute coronary syndrome within 6 months of screening or major surgery within 3 months
of Screening

7. Other types of amyloidosis

8. Have any other conditions, which, in the opinion of the Investigator or Sponsor would
make the subject unsuitable for inclusion, or could interfere with the subject
participating in or completing the Study

9. Current treatment with any approved drug for hereditary TTR amyloidosis such as
Vyndaqel® / Vyndamax™ (tafamidis), Tegsedi™ (inotersen), Onpattro™ (patisiran),
off-label use of diflunisal or doxycycline, and tauroursodeoxycholic acid (TUDCA). If
previously treated with Vyndaqel® / Vyndamax™, diflunisal or doxycycline, and TUDCA,
must have discontinued treatment for at least 2 weeks prior to Study Day 1

10. Previous treatment with Tegsedi™ (Inotersen) or Onpattro™ (patisiran), or other
oligonucleotide or RNA therapeutic (including siRNA)
