immunology - psoriasis

We understand your stress and fear about psoriasis, and how debilitating this and other immune-mediated diseases can be. That’s why we’re fully committed to pursuing transformational treatments to help you and the millions of other sufferers around the world.

Our focus in Dermatology: psoriasis


Our main focus is psoriasis, a chronic, disfiguring disease affecting the skin for which there is no cure.[1]

The most common form of psoriasis is plaque psoriasis, which usually results in patches of thick, red or inflamed skin covered with silvery scales, which are called plaques.[2]
The unpredictable nature of these plaques means that many patients fear they will return even when their condition has been brought under control.

What we’ve achieved

Janssen has played a leading role in the advancement of both transformational treatments and understanding of the underlying science of psoriasis for the past decade.

We’re committed to developing better treatments for those living with psoriasis, given the physical and psychological effect it has on those living with the condition.

We pursue innovative study concepts, such as evaluating the possibility of prolonged treatment intervals or intermittent therapy in psoriasis.

Our aim is to restore balance to the immune system with innovative treatments that either engage the brakes or block the accelerators of the immune system. In the future we aim to use these therapeutic approaches simultaneously to provide patients with even better outcomes.
