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 against psoriasis compared to a placebo (dummy pill) and Apremilast (an approved treatment). Participants will be randomly assigned to one of these treatments for 24 weeks.
What are the potential side effects?
Possible side effects include reactions similar to those seen in other psoriasis treatments: skin irritation, gastrointestinal issues, headaches, potential impact on mood or heart function as monitored through tests.
