Plaque psoriasis is an autoimmune condition characterised by dry, itchy and scaly skin patches. This trial investigates whether people with plaque psoriasis may be able to take an oral treatment to improve the condition.

Currently recruiting
HREC ethics approval number 2023.199

The investigational treatment in this study is JNJ-77242113 and is given as an oral tablet.

In a previous study, this tablet, JNJ-77242113, substantially cleared plaque psoriasis in participants. 

The purpose of this research project is to measure how safe and effective this medication is in treating participants with plaque psoriasis. It is a three-year study, which aims to understand the medication’s inhibiting effect on the body’s inflammatory response. The outcome of this project could support new treatments to increase quality of life in people with plaque psoriasis.

Anticipated date that enrolment will close: March 2024
