Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Clinical diagnosis of PN ≥ 3 months before screening.
  • Pruriginous lesions (defined as papules, nodules, plaques, umbilicated lesions, and linear lesions) on ≥ 2 different body areas (such as right and left leg) at screening and baseline.
  • Total estimated treatment BSA ≥ 25% (excluding the scalp) at screening and baseline.
  • IGA-CPG-S score of ≥ 2 at screening and baseline.
  • Baseline PN-related WI-NRS score ≥ 7. Baseline WI-NRS score is defined as the 7-day average of WI-NRS scores before Day 1 (data from a minimum of 4 out of 7 days prior to Day 1 is needed).

Exclusion Criteria:

  • Chronic or acute pruritus due to a condition other than PN.
  • Active AD lesions (signs and symptoms other than dry skin) within 6 months of screening and baseline.
  • Acute or chronic active HBV or HCV infection.
  • Any underlying condition known to be associated with the clinical presentation of PN that is not under control (stable) prior to the baseline visit.
  • Any serious illness or medical, physical, or psychiatric condition(s) that, in the investigator's opinion, would interfere with full participation in the study, including administration of study cream and attending required study visits; pose a significant risk to the participant; or interfere with interpretation of study data.

Other protocol-defined Inclusion/Exclusion Criteria may apply.

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

Experimental: Maximal Use Ruxolitinib 1.5%
Participants will apply ruxolitinib 1.5% cream BID through Week 4 to all pruriginous lesions. At Week 4, participants who have completed 4 weeks of treatment with no safety concerns may enter the optional 4-week treatment extension period, during which all participants will apply ruxolitinib 1.5% cream BID to existing pruriginous lesions.
Drug: Ruxolitinib Cream 1.5%

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of participants with Treatment-emergent Adverse Events (TEAEs)
Time Frame: Up to 16 weeks, including 30 days of safety follow-up
Defined as adverse events reported for the first time or worsening of a pre-existing event after first dose of study drug.
Up to 16 weeks, including 30 days of safety follow-up
Number of participants with TEAEs leading to dose interruption or discontinuation
Time Frame: Up to 16 weeks, including 30 days of safety follow-up
Number of participants with TEAEs leading to dose interruption or discontinuation.
Up to 16 weeks, including 30 days of safety follow-up

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Ruxolitinib pharmacokinetic (PK) parameters in plasma
Time Frame: Up to 16 weeks, including 30 days of safety follow-up
Ruxolitinib concentration in plasma.
Up to 16 weeks, including 30 days of safety follow-up

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
