About this study
Official title: An Extension Study in Patients With Moderate to Severe Plaque Psoriasis to Evaluate the Long-term Safety, Efficacy, and Durability of Response to ESK-001
The objective of the ESK-001-018 long term extension is to evaluate the safety and efficacy of ESK-001 over time. The scientific questions it aims to answer are:
- How safe is taking ESK-001 long-term in people with moderate to severe plaque psoriasis?
- Does taking ESK-001 long-term reduce the severity of people's plaque psoriasis?
Read more
Patients will enter the long-term extension study following completion of one of the parent studies (ESK-001-016 or ESK-001-017) and will receive open-label ESK-001 twice daily for 24 weeks. After 24 weeks, the first 200 patients meeting at least PASI-75 clinical response will be randomly assigned to receive ESK-001 or placebo. At any point during this time, the patients losing the initial clinical response may return to the open-label ESK-001 treatment. Patients who complete Week 48 will return to open-label ESK-001 treatment and they will receive ESK-001 until the end of the study or discontinuation. All the remaining patients not meeting the entry criteria for the randomized withdrawal phase will continue to receive open-label ESK-001 for the remainder of the study.
Patients taking part in the study must be men or women aged at least 18 years old and have completed a previous (parent) study of ESK-001 in moderate to severe plaque psoriasis.
Patients must consent and agree to:
- ensure drug daily compliance until end of study or discontinuation.
- visit the clinic for checkups and assessments.
- provide blood and urine samples.

Measured: 24, 48, 72, and 96 weeks
To assess the long-term efficacy of ESK-001 based on change in Psoriasis Area and Severity Index (PASI)
Change in Psoriasis Area and Severity Index (PASI) from baseline assessments
Measured: 24, 48, 72, and 96 weeks
To assess the long-term efficacy of ESK-001 based on change in Affected Body Surface Area (%BSA)
Change in affected body surface area (%BSA) from baseline assessments
Measured: 24, 48, 72, and 96 weeks
To characterize the loss of PASI-75 response following withdrawal of ESK-001 treatment (only for patients randomized to the treatment withdrawal phase)
Median time to loss of PASI-75 response
Measured: Week 48
To characterize the loss of PASI-90 response following withdrawal of ESK-001 treatment (only for patients randomized to the treatment withdrawal phase)

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The objective of the ESK-001-018 long term extension is to evaluate the safety and efficacy of ESK-001 over time. The scientific questions it aims to answer are:
- How safe is taking ESK-001 long-term in people with moderate to severe plaque psoriasis?
- Does taking ESK-001 long-term reduce the severity of people's plaque psoriasis?
Patients will enter the long-term extension study following completion of one of the parent studies (ESK-001-016 or ESK-001-017) and will receive open-label ESK-001 twice daily for 24 weeks. After 24 weeks, the first 200 patients meeting at least PASI-75 clinical response will be randomly assigned to receive ESK-001 or placebo. At any point during this time, the patients losing the initial clinical response may return to the open-label ESK-001 treatment. Patients who complete Week 48 will return to open-label ESK-001 treatment and they will receive ESK-001 until the end of the study or discontinuation. All the remaining patients not meeting the entry criteria for the randomized withdrawal phase will continue to receive open-label ESK-001 for the remainder of the study.
Patients taking part in the study must be men or women aged at least 18 years old and have completed a previous (parent) study of ESK-001 in moderate to severe plaque psoriasis.
Patients must consent and agree to:
- ensure drug daily compliance until end of study or discontinuation.
- visit the clinic for checkups and assessments.
- provide blood and urine samples.

Who may be eligible to take part?
The sponsor lists 4 inclusion and 3 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: under way, not looking for participants, as of the sponsor's last update on 13 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 268 sites in United States, Poland, Canada, Germany, Japan and 11 more countries. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
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?
To assess the long-term safety and tolerability of ESK-001 throughout the duration of the study (time frame: Approximately 4 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 13 Apr 2026.
