Predicting sensitivity to glucocorticoid therapy for chronic rhinosinusitis with nasal polyps

Establishment of CST1 Predictive Model of Oral Glucocorticoid Therapy Sensitivity for Chronic Rhinosinusitis With Polyps

Phase 4 Interventional Beijing Tongren Hospital · NCT05598424

This study is testing if measuring certain levels in nasal secretions can help predict how well people with chronic rhinosinusitis and nasal polyps will respond to treatment with oral glucocorticoids.

What this trial studies

This clinical trial aims to develop a predictive model for oral glucocorticoid therapy sensitivity in patients with chronic rhinosinusitis with nasal polyps by measuring CST1 levels in nasal secretions. It is a single-arm, multicenter trial that evaluates patients before and after treatment with oral glucocorticoids. Key assessments include endoscopic polyp scores, Total Nasal Symptom Scores (TNSS), and SNOT-22 scores to determine treatment efficacy. The study seeks to identify biomarkers that correlate with treatment response, potentially improving patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-70 diagnosed with chronic rhinosinusitis with nasal polyps and exhibiting significant nasal polyp size.

Not a fit: Patients with contraindications to oral glucocorticoids or those with specific conditions like fungal sinusitis or cystic fibrosis may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized and effective treatment strategies for patients with chronic rhinosinusitis with nasal polyps.

How similar studies have performed: While the approach of using CST1 levels to predict glucocorticoid sensitivity is novel, similar studies have shown promise in identifying biomarkers for treatment response in other conditions.
