About this study

Official title: An Open Label, Safety, Tolerability, Pharmacokinetic (PK), Pharmacodynamic (PD) and Preliminary Efficacy Study of Ruxolitinib When Applied to Patients With Plaque Psoriasis Involving 2 - 20% Body Surface Area (BSA).

This will be an open label study of ruxolitinib topical cream applied to 2 - 20% BSA in patients with active, stable plaque psoriasis.

Conditions: Psoriasis
Being tested: Ruxolitinib
Keywords: psoriasis
Medical subject headings: Psoriasis

Study groups in NCT00617994
Study group	Role	What they receive

What is being measured

The primary outcome is the main question the study is designed to answer.

Number of Treatment of Emergent Adverse Events
Adverse events reported for the first time or worsening of a pre-existing event after first dose of study drug/treatment
Measured: Approximately 3 months
Pharmacokinetics Parameter : Skin Flux of INCB018424
The INCB018424 skin flux was estimated from the overall mean steady-state plasma concentrations for each subject in this study and the estimated systemic clearance of INCB018424 following oral-dose administration in another study.
Measured: Days 1, 4, 8, 15, 22, and 28-30
Pharmacokinetics Parameter: Bioavailability of INCB018424
The INCB018424 bioavailability was estimated from the overall mean steady-state plasma concentrations for each subject in this study and the estimated systemic clearance of INCB018424 following oral-dose administration in another study.
Measured: Approximately one month: Days 1, 4, 8, 15, 22, and 28
Pharmacokinetics Parameter: Plasma Concentrated Steady State (CSS) of INCB018424
All observed INCB018424 plasma concentrations from Days 8, 15, 22, and 28 were averaged to obtain an overall mean exposure for each subject. Samples were taken pre-dose and approximately one hour post-dose.
Measured: Approximately one month: Days 1, 4, 8, 15, 22, and 28

Secondary outcomes (3)

Psioriatic Lesion Severity: Change in Total Lesion Score for the Target Lesion Compared to Baseline
Changes in total lesion scores were compared to baseline score. Lesions were compared between active treated areas INCB018424 and control areas of the same subject (within-subject comparisons) using one sample t-test. Total lesion score was calculated as the sum of the scores for Thickness (T), erythema (E), and scaling (S) for the target and control lesions. All individual scores use a 5-point scale ranging from 0 (none) to 4 (severe) with increasing score reflecting increased lesion severity. These ratings are then added to create a total score ranging from 0 to 12.
Measured: Approximately 2 months (Days 1, 8, 15, 22, 28 and up to an additional 28 day Follow-Up)
Mean Change in Psoriatic Lesion Area
The target and control lesion areas were determined in an objective manner on Day 1 and Day 28 based on a tracing of the perimeter of the lesions on transparency film and measurement of the area.
Measured: Days 1 and 28
Mean Change in Physicians Global Assessment Score
The PGA was an overall assessment of each participant's plaque psoriasis. The assessment was recorded using a scale that ranged from 0 (clear) to 6 (most severe) in whole-unit increments.
Note that, for analysis purposes, the scale was adjusted to range from 1 (clear) to 7 (most severe) to allow for the evaluation of mean scores.
Measured: Approximately 2 months: Days 1, 8, 15, 22, 28 and follow-up approximately one month later

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ruxolitinib in people with Psoriasis, run by Incyte Corporation at 4 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 8 Feb 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Treatment of Emergent Adverse Events (time frame: Approximately 3 months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00617994.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Feb 2022; AzTrials last refreshed its copy on 8 Nov 2026.
