Identifying Predictive Markers for Psoriasis Treatment Response

Development of Predictive Psoriasis Response Endotypes Using Single Cell Transcriptomics in Ustekinumab Responders Versus Non-responders

Phase 4 Interventional University Hospitals Cleveland Medical Center · NCT05270733

This study is testing if certain genetic markers can help predict how well people with psoriasis will respond to two different medications over eight weeks.

What this trial studies

This study aims to enhance psoriasis treatment by identifying genetic markers that predict how patients will respond to specific biologic therapies. Participants will receive two FDA-approved psoriasis medications over an 8-week period, during which their skin condition will be monitored, and biological samples will be collected for analysis. The goal is to develop a personalized treatment approach that minimizes the trial-and-error method currently used in psoriasis management.

Who should consider this trial

Good fit: Ideal candidates are individuals diagnosed with plaque-type psoriasis who are naive to the studied biologic therapies and have a significant body surface area involvement.

Not a fit: Patients who are currently pregnant, breastfeeding, or unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective and personalized treatment options for psoriasis patients.

How similar studies have performed: Other studies have shown promise in using genetic markers to predict treatment responses in various conditions, suggesting potential success for this novel approach in psoriasis.
