Eligibility
Key inclusion criteria
Healthy Subjects:

- Age 18 to 60 years, inclusive

- Body mass index greater than or equal to 19 to less than or equal to 35 kg/m2

examination, vital sign, standard 12- lead ECG, chemistry, hematology, urinalysis, or
coagulation results at Screening as deemed by the Investigator

- Male and female subjects must use adequate birth control and agree not to donate sperm
or eggs for the time periods specified in the protocol

Subjects with Cholestatic Pruritus:

- Age 18 to 80 years, inclusive

- Has a cholestatic disorder

- Has experienced daily or near-daily moderate to severe pruritus for greater than 4
weeks before Screening and at study entry has itch scores indicative of moderate to
severe pruritus

- If currently taking medications to treat the cholestatic disorder, must be on a stable
dose for greater than 12 weeks before Screening and plans to maintain the regimen
throughout the study

- If currently taking medications known to impact pruritus, must be on a stable dose for
greater than 4 weeks before Screening and plans to maintain the regimen throughout the
study

- Male and female subjects must use adequate birth control and agree not to donate sperm
or eggs for the time periods specified in the protocol

Subjects with Uremic Pruritus

- Age 18 to 80 years, inclusive

- Has ESRD and is receiving hemodialysis 3× per week

- Has experienced daily or near-daily moderate to severe pruritus for greater than 4
weeks before Screening and at study entry has itch scores indicative of moderate to
severe pruritus

- If currently taking medications known to impact pruritus, must be on a stable dose for
greater than 4 weeks before Screening and plans to maintain the regimen throughout the
study

- Male and female subjects must use adequate birth control and agree not to donate sperm
or eggs for the time periods specified in the protocol
Minimum age
18 Years
Maximum age
80 Years
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
Healthy Subjects:

- Any prescription medications within 14 days of Screening

- Positive result for HIV HBV, or HCV at Screening

- History of malignancy within the past 5 years

- Tobacco product or electronic cigarette use within 90 days of Day -1

- Positive drug, alcohol, or cotinine screen results at Screening or Day -1

- Significant history of abuse of drugs, solvents, or alcohol in the past 2 years

Subjects with Cholestatic Pruritus:

- Scheduled to receive a liver transplant during the study (placement on a transplant
waiting list is not exclusionary)

- Is receiving ongoing UVB treatment or anticipates receiving such treatment during the
study

- Pruritus is secondary to biliary obstruction

- History or presence of hepatocellular carcinoma, hepatic abscess, or acute portal vein
Thrombosis

Subjects with Uremic Pruritus:

- Scheduled to receive a kidney transplant during the study (placement on a transplant
waiting list is not exclusionary)

- Is receiving ongoing UVB treatment or anticipates receiving such treatment during the
study

- Known noncompliance with hemodialysis treatment that, in the opinion of the
Investigator, would impede completion or validity of the study

- Pruritus is attributed mainly to any disease unrelated to kidney disease, is only
present during the hemodialysis sessions, or is attributed to a skin disorder that
occurs in this population with associated itch (eg, acquired perforating dermatosis)
