Monitoring Tildrakizumab Levels in Psoriasis Patients

Evaluation of the Predictive Value of Early Serum Trough Concentrations and Anti-drug Antibodies of Tildrakizumab and the Development of a Concentration Response Curve of Tildrakizumab for Psoriasis Patients

Phase 4 Interventional University Hospital, Ghent · NCT05683015

This study tests how well a psoriasis medication called tildrakizumab works for patients by checking its levels in their blood and seeing how it affects their daily lives.

What this trial studies

This study investigates the therapeutic drug monitoring of tildrakizumab, a biologic treatment for moderate to severe psoriasis. Patients will receive standard doses of tildrakizumab while their serum trough levels and anti-drug antibodies will be measured at each visit. The study aims to determine the optimal therapeutic window for this medication, potentially leading to more personalized treatment approaches. Additionally, patients will complete quality of life assessments to evaluate the impact of treatment on their daily lives.

Who should consider this trial

Good fit: Ideal candidates are individuals with chronic plaque-type psoriasis who are willing to participate in the study and undergo multiple blood draws.

Not a fit: Patients with nonplaque forms of psoriasis, those who are pregnant or nursing, or those on a different dosing schedule will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective and personalized dosing of tildrakizumab, improving treatment outcomes for psoriasis patients.

How similar studies have performed: Other studies have shown promise in therapeutic drug monitoring for biologics, suggesting that this approach could be beneficial for optimizing treatment.
