Time frame: Week 24

Secondary Outcomes

Defined as percentage of participants that achieve a ≥ 4-point improvement (reduction) in Itch NRS score from baseline.

Time frame: Week 24

Proportion of participants achieving IGA-CPG-S-TS at Week 24

Time frame: Week 24

Proportion of participants achieving Itch NRS4 at Week 4

Defined as percentage of participants that achieve a ≥ 4-point improvement (reduction) in Itch NRS score from baseline.

Time frame: Week 4

Time to Itch NRS4

Time frame: Up to 52 weeks

Change from baseline in Itch NRS score at each postbaseline visit

Itch will be measured using an NRS used to indicate the intensity of the worst itching over the past 24 hours using a 0 to 10 numeric rating scale, where "0" represents "no itching" and "10" represents "worst itching imaginable".

Time frame: Up to 52 weeks

Percent change from baseline in NRS score at each postbaseline visit
