CST1-Guided Oral Glucocorticoids Management for CRSwNP
- Conditions
- Chronic Rhinosinusitis With Nasal PolypsGlucocorticoids
- Interventions
- Drug: Oral placeboDrug: Oral Glucocorticoids
- Registration Number
- NCT05598411
- Lead Sponsor
- Beijing Tongren Hospital
- Brief Summary
Topical and systemic steroids constitute the first choice in medical treatment for nasal polyps. Glucocorticoids sensitivity is significantly correlated with CST1 in nasal secretions. The goal of this randomized, double-blind, placebo-controlled clinical trial is to clarify the efficacy of a short course of CST1-guided oral glucocorticoids therapy for chronic rhinosinusitis with nasal polyps. Subjects were randomized to receive either oral glucocorticoids or oral placebo for 2 weeks. Endoscopic polyp score, Total Nasal Symptom Score(TNSS), SNOT-22 score, Cystatin 1 and other biomarkers were evaluated before and after the treatment. Researchers will compare oral glucocorticoids group and oral placebo group to test CST1 predictive model of glucocorticoid therapy for Chronic Rhinosinusitis with Polyps.

Group Intervention Description Placebo group Oral placebo Intervention Period：oral placebo+nasal spray（oral placebo 24mg qd, 2-week duration）+nasal spray （Budesonide Nasal Spray 64ug per Nostril, bid, 2-week duration） follow-up period：nasal spray（Budesonide Nasal Spray 64ug per Nostril, bid, 24-week duration） Oral Glucocorticoids group Oral Glucocorticoids Intervention Period：oral glucocorticoids（methylprednisolone 24mg qd, 2-week duration）+nasal spray （Budesonide Nasal Spray 64ug per Nostril, bid, 2-week duration） follow-up period：nasal spray（Budesonide Nasal Spray 64ug per Nostril, bid, 24-week duration）
- Primary Outcome Measures
Name Time Method The change in endoscopic polyp score Baseline, week 2, week 6, week 10, week 14, week 18, week 22, week 26 Bilateral polyp volume size described using the Nasal Polyp Size Score (NPSS) score. (0 - 4 points per side: 0 = no polyp; 1 = small polyp in the middle meatus, not reaching the inferior border of the middle turbinate; 2 = small polyp in the middle meatus, reaching the inferior border of the middle turbinate; 3 = large polyp protruding from the middle meatus, not reaching the inferior border of the inferior turbinate; 4 = large polyp that almost causes most or complete obstruction of the nasal cavity.)
- Secondary Outcome Measures
Name Time Method The change in asthma ACQ Score Baseline, week 2, week 6, week 10, week 14, week 18, week 22, week 26 For patients with asthma, we assessed the change of asthma symptoms through the Asthma Control Questionnaire(ACQ). Each question was scored on a scale of 0 to 6 according to the severity. The result score of each item was averaged. A score of \<0.75 indicated that the asthma had been completely controlled; a score of 0.75-1.5 indicates well-controlled asthma; a score of \>1.5 indicates that asthma is not controlled.
The change in Total Nasal Symptom Score（TNSS） Baseline, week 2, week 6, week 10, week 14, week 18, week 22, week 26 Total Nasal Symptom Score was are graded on a 3-point scale. (0= no symptoms; 1= mild symptoms; 2= moderate symptoms; 3= severe symptoms).
The change of biomarker Baseline, week 2, week 6, week 10, week 14, week 18, week 22, week 26 Changes in expression levels of biomarker in nasal brush exfoliated cells, nasal secretions and nasal microbes.
The change in SNOT-22 score Baseline, week 2, week 6, week 10, week 14, week 18, week 22, week 26 The 22-item Sino-nasal outcome test (SNOT-22) was used to evaluate the changes in symptoms of patients. According to the severity of symptoms caused by RCRS, each item was divided into 6 levels: no distress (0 points), mild distress (1 point), mild distress (2 points) ), moderate distress (3 points), severe distress (4 points), very severe distress (5 points). The higher the score, the more severe the symptoms, and the final total score of the item is counted.
The needs of upgrading treatment Baseline, week 2, week 6, week 10, week 14, week 18, week 22, week 26 The needs of upgrading treatment includes surgery, oral glucocorticoids or monoclonal antibodies treatment.
The change of CST1 Baseline, week 2, week 6, week 10, week 14, week 18, week 22, week 26 The change of Cystatin 1
The change in AE / SAE recording Baseline, week 2, week 6, week 10, week 14, week 18, week 22, week 26 Any adverse event
The change of inflammatory cell Baseline, week 2, week 26 The change of inflammatory cell in nasal polyps
