Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with moderate to severe psoriasis affecting more than 5% of their body surface area.

Probably not a fit

Patients currently taking systemic immunosuppressives, pregnant or breastfeeding women, and those with severe immunodeficiency or active infections 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 examines the immune response of patients with moderate to severe psoriasis before and after treatment with Tildrakizumab, an IL23 blocker. It is a one-arm, open-label study involving ten subjects who will undergo biopsy and blood sample collection for molecular profiling. The goal is to evaluate how Tildrakizumab affects immune cell function in the skin and blood of these patients.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding of immune responses in psoriasis and enhance treatment strategies.

How similar studies have gone: Other studies have shown promising results with IL23 blockers in treating psoriasis, indicating a potential for success in this approach.
