Official Title
Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Effects of EP547 in Subjects With Cholestatic Pruritus Due to Primary Biliary Cholangitis or Primary Sclerosing Cholangitis
Primary Outcomes
Outcome Description
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)
Outcome Measure
Change in Worst Itch Numeric Rating Scale (WI-NRS)
Outcome Time Frame
Measured from Baseline to Week 6
Secondary Outcomes
Outcome Description
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
Outcome Time Frame
Measured from Baseline to Week 6
Outcome Measure
Change in 5-D Itch Scale
Outcome Description
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
Outcome Time Frame
Measured at Week 6
Outcome Measure
Proportion of subjects with improvement in pruritus as defined by PGI-C
Outcome Description
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
Outcome Time Frame
Measured from Baseline to Week 6
Outcome Measure
Proportion of subjects with improvement in pruritus severity from baseline as defined by PGI-S
Outcome Description
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)
Outcome Time Frame
Measured from Baseline to Week 6
Outcome Measure
Proportion of subjects with a reduction in WI-NRS ≥2 from baseline
Outcome Description
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)
Outcome Time Frame
Measured from Baseline to Week 6
Outcome Measure
Proportion of subjects with a reduction in WI-NRS ≥3 from baseline
Outcome Description
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)
Outcome Time Frame
Measured from Baseline to Week 6
Outcome Measure
Proportion of subjects with a reduction in WI-NRS ≥4 from baseline
Outcome Description
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)
Outcome Time Frame
Measured from Baseline to Week 6
Outcome Measure
Proportion of subjects with WI-NRS <4
Outcome Description
Safety and tolerability of EP547 measured through reporting of adverse events
Outcome Time Frame
Measured from Day 1 to End of Study or Early Termination (up to Week 6)
Outcome Measure
The incidence of adverse events
Outcome Description
To evaluate the pharmacokinetics of EP547
Outcome Time Frame
Measured from Day 1 to Week 6
Outcome Measure
Maximum Plasma Concentration [Cmax]
