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 participants 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
