Brief Summary

The purpose of this study is to evaluate the safety and tolerability of Ruxolitinib cream in participants with Prurigo Nodularis (PN).

Detailed Description

The study comprises of a 12 week double-blind, vehicle-controlled (DBVC) treatment period, followed by a 40 week open label extension period, and 30 day safety follow-up period During the double blind period, all PN-affected areas identified at baseline will be treated, and during the open label period, only active PN-affected areas will be treated.

Vehicle Cream BIDVehicle CreamParticipants 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.

Primary Outcome Measures
NameTimeMethod
Worst-Itch Numeric Rating Scale (WI-NRS) ≥ 4-point improvement in WI-NRS score ResponseWeek 12

Defined as achieving a ≥ 4-point improvement (reduction) in Worst Itch Numeric Rating Scale (WI-NRS) score from baseline.

Secondary Outcome Measures
NameTimeMethod
Overall Treatment Success (TS)Week 12

Defined as achieving both a WI-NRS4 response and an Investigator's Global Assessment for Stage of Chronic Prurigo Treatment Success (IGA-CPG-S-TS).

IGA-CPG-S-TSWeek 12

Defined as an IGA-CPG-S score of 0 or 1 with a ≥ 2 grade improvement from baseline

Time to ≥ 4-point improvement from baseline in WI-NRS scoreUp to 52 weeks

Defined as time taken for the participant to achieve a ≥4 improvement in NRS scale compared to baseline

Change from baseline in Skin Pain NRS scoreUp to 52 weeks

Itch NRS is an 11-point scale (0 to10) where 0 is "no itch" and 10 is the "worst itch imaginable".

Proportion of participants with WI-NRS4 at each postbaseline visit.Up to 52 weeks

Defined as percentage of participants that achieve a ≥ 4-point improvement in WI-NRS score

IGA-TS response, defined as achieving IGA TS at each postbaseline visit.Up to 56 weeks

The IGA for chronic prurigo nodularis considers the number of nodules, also referred to as lesions, and uses them to determine an overall severity rating on on a 5-point scale ranging from 0 (clear skin) to 4 (severe).

> 75% healed lesions from baseline in PAS at each postbaseline visit.Up to 56 weeks

PAS includes 5 items; descriptive of the type, predominant type, distribution, and quantity of pruriginous lesions, and disease activity in terms of percentage of pruriginous lesions with excoriations/crusts on top.

Change from baseline in EQ-5D-5L score at each postbaseline visit.Up to 56 weeks

The EQ-5D-5L questionnaire is a standardized, validated instrument for use as a measure of health outcome

WI-NRS4 ResponseDay 7

Defined as achieving a ≥ 4-point improvement (reduction) in WI-NRS score from baseline.

Change from baseline in WI-NRS scoreUp to 52 weeks

Defined as change in Intensity of itch. 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".

Change from baseline in Dermatology Life Quality Index (DLQI) score at each postbaseline visit.Up to 56 weeks

The DLQI is a simple, 10-question validated questionnaire to measure how much the skin problem has affected the participant over the previous 7 days

Time to ≥ 2-point improvement from baseline in WI-NRS scoreUp to 52 weeks

Participants rate pruritus daily on Worst Itch \[pruritis\] Numerical Rating Scale (0=no pruritus; 10=worst imaginable pruritus)

Skin pain response, defined as a ≥ 2-point improvement in Skin Pain NRS scoreUp to 52 weeks

Itch NRS is an 11-point scale (0 to10) where 0 is "no itch" and 10 is the "worst itch imaginable".

IGA-CPG-A 0 or 1 response, defined as achieving an IGA score of 0 or 1 at each postbaseline visit.Up to 56 weeks

The IGA-CPG-A is an overall PN severity rating on a 5-point scale ranging from 0 (clear skin) to 4 (severe disease). The score is based on an overall assessment of the degree of erythema, induration/papulation, and oozing/crusting.

Number of Treatment-emergent adverse events (TEAEs)Up to 56 weeks

TEAE defined as any adverse event either reported for the first time or worsening of a pre-existing event after first dose of study drug.
