Identifying biomarkers for response to mepolizumab in patients with nasal polyps and asthma

Novel Insight in pathologiCal and clinicAl Attributes in Response to mepoLizumab Treatment in Patients With Chronic rhInosinusitis With Nasal pOlyPs With or Without bronchIal Asthma on a Long-term Basis (CALIOPI STUDY)

Observational Aristotle University Of Thessaloniki · NCT05708300

This study is testing if mepolizumab can help people with nasal polyps and asthma feel better, while also looking for signs that show who will benefit from the treatment.

What this trial studies

This observational study investigates the effectiveness of mepolizumab, a biologic treatment, in patients suffering from chronic rhinosinusitis with nasal polyps, with or without bronchial asthma. The study aims to evaluate airway remodeling and identify biomarkers that differentiate responders from non-responders to the treatment over a period of 156 weeks. Patients will undergo endobronchial and nasal biopsies as part of routine care to assess tissue changes and inflammatory characteristics. The findings could enhance treatment strategies for chronic rhinosinusitis and asthma by providing insights into the underlying mechanisms of response to therapy.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with bilateral nasal polyps and significant symptoms despite standard treatment.

Not a fit: Patients who have previously received biologic therapy or are currently pregnant or nursing may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized treatment approaches for patients with nasal polyps and asthma, improving their quality of life.

How similar studies have performed: While the approach of identifying biomarkers in this context is novel, other studies have shown success with biologic treatments for asthma and nasal polyps.
