Dupilumab for early and long-term symptom relief and immune changes in prurigo nodularis

Early and Long-term Clinical Efficacy and Local Tissue and Peripheral Immune Changes Following Dupilumab Treatment in Prurigo Nodularis Patients

Observational UMC Utrecht · NCT07276425

This project will try dupilumab in adults with moderate-to-severe prurigo nodularis to see if it reduces itching and nodules and causes measurable immune changes over time.

What this trial studies

This is an observational, real-world study following adults with moderate-to-severe prurigo nodularis who start treatment with dupilumab. Patients are enrolled in the BioDay registry and some may consent to provide samples to the UMC Utrecht Biobank for translational analyses. The study will track early and long-term clinical outcomes (symptoms and lesion changes) alongside immune markers to understand how dupilumab acts in routine clinical care. Findings aim to link clinical response with immune changes to help personalize treatment.

Who should consider this trial

Good fit: Adults with moderate-to-severe prurigo nodularis who are beginning dupilumab treatment and are willing to join the BioDay registry (and optionally the Biobank) are ideal candidates.

Not a fit: Patients with mild prurigo nodularis, those not starting dupilumab, or those unwilling to participate in the registry or provide samples for translational analyses are unlikely to benefit from this study's findings.

Why it matters

Potential benefit: If successful, the study could help clinicians better predict who will benefit from dupilumab and tailor treatment plans for longer-lasting symptom control.

How similar studies have performed: Randomized trials and clinical reports have shown dupilumab can reduce itch and lesions in prurigo nodularis, but detailed real-world and immune-mechanism data remain limited.
