Primary Outcome Measures
NameTimeMethod
Change in Worst Itch Numeric Rating Scale (WI-NRS)Measured from Baseline to Week 6

Pruritus will be measured using a WI-NRS scale to indicate the intensity of itch in the past 24 hours from 0 (No Itching) to 10 (Worst Itching Imaginable)

Secondary Outcome Measures
NameTimeMethod
Proportion of subjects with improvement in pruritus severity from baseline as defined by PGI-SMeasured from Baseline to Week 6

Pruritus will be measured using the PGI-S scale to indicate severity of itch in the past 7 days using a 4-point scale from none to severe

Change in 5-D Itch ScaleMeasured from Baseline to Week 6

The 5-D Itch Scale will be used to measure change in pruritus covering five dimensions: degree, duration, direction, disability, and distribution. The total 5-D Itch Scale score ranges from 5 to 25, with higher scores indicating worse quality of life

Proportion of subjects with a reduction in WI-NRS โ‰ฅ3 from baselineMeasured from Baseline to Week 6

Pruritus will be measured using a WI-NRS scale to indicate the intensity of itch in the past 24 hours from 0 (No Itching) to 10 (Worst Itching Imaginable)

The incidence of adverse eventsMeasured from Day 1 to End of Study or Early Termination (up to Week 6)

Safety and tolerability of EP547 measured through reporting of adverse events

Proportion of subjects with improvement in pruritus as defined by PGI-CMeasured at Week 6

Change in pruritus will be measured using the PGI-C scale to indicate overall change in pruritus in the past 7 days compared to before treatment using a 7-point scale from much improved to much worse

Proportion of subjects with a reduction in WI-NRS โ‰ฅ4 from baselineMeasured from Baseline to Week 6

Pruritus will be measured using a WI-NRS scale to indicate the intensity of itch in the past 24 hours from 0 (No Itching) to 10 (Worst Itching Imaginable)

Proportion of subjects with a reduction in WI-NRS โ‰ฅ2 from baselineMeasured from Baseline to Week 6

Pruritus will be measured using a WI-NRS scale to indicate the intensity of itch in the past 24 hours from 0 (No Itching) to 10 (Worst Itching Imaginable)

Proportion of subjects with WI-NRS <4Measured from Baseline to Week 6

Pruritus will be measured using a WI-NRS scale to indicate the intensity of itch in the past 24 hours from 0 (No Itching) to 10 (Worst Itching Imaginable)

Maximum Plasma Concentration [Cmax]Measured from Day 1 to Week 6

To evaluate the pharmacokinetics of EP547
