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.

Who should consider this trial

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

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.

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