Summary

This trial aims to see if ESK-001 is effective in treating moderate to severe plaque psoriasis and how safe it is for patients. Participants will take ESK-001 daily for 24 weeks

Who is the study for?
Adults aged 18+ with moderate to severe plaque psoriasis for at least 6 months can join this study. They'll take a daily drug for half a year, visit the clinic regularly, and report on their skin condition, itchiness, and life quality changes.
What is being tested?
The trial is testing ESK-001's effectiveness in treating plaque psoriasis compared to a placebo (dummy pill) and Apremilast (an approved treatment). Participants will be monitored through clinic visits, questionnaires, health checks, heart activity tests, and by providing blood/urine samples.
What are the potential side effects?
Possible side effects of ESK-001 may include reactions similar to those experienced with other psoriasis treatments such as digestive issues, headaches, fatigue. The exact side effects will be studied during the trial.
