This clinical trial is focused on studying the long-term safety and effectiveness of a medication called deucravacitinib in individuals with moderate-to-severe plaque psoriasis. Plaque psoriasis is a skin condition that causes red, scaly patches to appear on the skin. The study involves taking deucravacitinib, which is provided in the form of a film-coated tablet, and aims to understand how safe and tolerable it is for long-term use in treating this condition.

Participants in the study will receive deucravacitinib, and some may receive a placebo to compare the effects. The study is designed to observe any side effects or adverse events that may occur over time. The goal is to gather information on how well the medication works and how safe it is for people with moderate-to-severe plaque psoriasis.

The study will be conducted over a period of time, allowing researchers to collect data on the medication’s impact on the skin condition. Participants will be monitored for any changes in their condition and any potential side effects. This information will help in understanding the long-term benefits and risks of using deucravacitinib for treating plaque psoriasis.
