Outcome Measures
Primary Outcomes (1)
WI-NRS4 Response at Week 12
WI-NRS4 was defined as the percentage of participants achieving a ≥4-point improvement (reduction) in Worst-Itch Numeric Rating Scale (WI-NRS) score from baseline. The WI-NRS is a patient-reported outcome comprised of a single item rated on a scale from 0 ("no itch") to 10 ("worst imaginable itch"). Participants assessed their worst level of prurigo nodularis-related itch during the past 24 hours on a scale of 0 to 10. The WI-NRS score for baseline was determined by averaging the 7 daily WI-NRS scores before Day 1 (i.e., Days -7 to -1) for all by-visit summaries. The by-visit WI-NRS score for post-baseline visits was determined by averaging the 7 daily WI-NRS scores before the visit day. Participants with missing Week 12 data for any reason, including treatment discontinuation (due to development of atopic dermatitis lesions or any other cause), were defined as nonresponders.

Study Arms (2)
Vehicle Cream BID
PLACEBO COMPARATORParticipants apply ruxolitinib matching vehicle cream topically to the affected areas as a thin film twice daily (BID) for 12 weeks during the DBVC period. Participants who have completed the treatment during DBVC period will apply ruxolitinib 1.5% cream topically during the open label extension (OLE) period for up to 40 weeks.
Ruxolitinib 1.5% Cream
EXPERIMENTALParticipants apply ruxolitinib 1.5% cream topically to the affected areas as a thin film BID for 12 weeks during the DBVC period. Participants who have completed the treatment during DBVC period will apply ruxolitinib 1.5% cream the open label extension (OLE) period for up to 40 weeks.
Interventions
Ruxolitinib cream 1.5% twice daily (BID) during the vehicle controlled (DBVC)and open label treatment period (OLE).
Ruxolitinib matching vehicle cream 1.5% twice daily (BID) during the vehicle controlled period (DBVC).
