A Study in Patients With Moderate to Severe Plaque Psoriasis to Evaluate the Efficacy and Safety of ESK-001

Phase 3
Active, not recruiting
Conditions
Plaque Psoriasis
Interventions
Registration Number
NCT06588738
Lead Sponsor
Alumis Inc
Brief Summary

The goal of this clinical trial is to learn if ESK-001 works to treat moderate to severe plaque psoriasis. The main questions it aims to answer are:

* Does ESK-001 reduce the severity of people's psoriasis?

* How safe is ESK-001 in people with moderate to severe plaque psoriasis?

The study includes 2 comparators: a placebo control (a 'dummy' tablet that does not contain the medicine ESK-001 but looks just like it) and an active control (apremilast, which is a medicine approved to treat psoriasis).

People taking part in this study must be men or women aged at least 18 years and have had plaque psoriasis for at least 6 months, currently moderate to severe.

Participants will:

* take drug every day for 24 weeks.

* visit the clinic for checkups and tests.

* fill out questionnaires about their psoriasis, itch severity, and change in quality of life.

* be assessed for health issues and side effects, physical examinations, vital signs, heart electrical activity measurements, and psychological health.

* provide blood and urine samples.
