Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with moderate to severe psoriasis.

Probably not a fit

Patients with severe immunodeficiency, active infections, or those on systemic immunosuppressives may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effects of deucravacitinib, a TYK2 inhibitor, on immune cell function in patients with moderate to severe psoriasis. It is a one-arm, open-label study involving 25 participants who will undergo biopsy and blood sampling before and during treatment. The goal is to analyze the molecular profiles of immune cells to determine how deucravacitinib alters psoriatic signatures.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the management of psoriasis by correcting immune cell dysfunction.

How similar studies have gone: Other studies have shown promise with TYK2 inhibitors in treating autoimmune conditions, suggesting potential success for this approach.
