Efficacy and Safety of Fully Resorbable Sinus Drug-eluting Stents in Patients With Eosinophilic Chronic Rhinosinusitis With Nasal Polyps After Surgery: A Prospective, Randomized Controlled Trial
China192 participantsStarted 2026-01-21
Plain-language summary
This study consists of two parts evaluating the efficacy and safety of a fully degradable sinus drug-eluting stent in patients with eosinophilic chronic rhinosinusitis with nasal polyps (ECRSwNP).
Part A assesses the efficacy and safety of the stent when used immediately after functional endoscopic sinus surgery (FESS).
Part B evaluates the stent in patients with early postoperative recurrence of ECRSwNP.
The study aims to answer the following key questions:
Does the use of the stent reduce the recurrence of nasal polyps?
Can the stent reduce the need for oral corticosteroids?
The fully degradable sinus drug-eluting stent is compared with intranasal corticosteroids (Part A) and oral corticosteroids (Part B) to determine whether it offers therapeutic benefit in the management of ECRSwNP.
Participant Procedures:
Part A: Participants will either receive the fully degradable sinus stent or daily intranasal corticosteroids for 6 months. Follow-up visits will occur at Week 2, Week 4, Week 8, Week 12, and Month 6 to record symptoms and adverse events.
Part B: Participants will either receive the fully degradable sinus stent or oral corticosteroids (based on disease progression) for 6 months. Follow-up visits will be conducted at Week 2, Week 4, Week 8, Week 12, and Month 6 for symptom assessment and documentation of adverse events.

Inclusion criteria
✓. Age 18-65 years.
✓. Diagnosis of chronic rhinosinusitis with nasal polyps (CRSwNP).
✓. Eosinophilic subtype confirmed by pathology (eosinophils \>27% of total infiltrating inflammatory cells in polyp tissue, OR absolute count \>55 eosinophils per high-power field (HPF) on H\&E staining).
✓. Indicated and scheduled for Functional Endoscopic Sinus Surgery (FESS) due to inadequate response to standard medical therapy for \>3 months, with bilateral endoscopic Nasal Polyp Score (NPS) ≥5 (max 8), each side ≥2, and presenting at least 2 of the following symptoms before screening: nasal blockage/congestion, anterior/posterior nasal discharge, facial pain/pressure, or reduced/loss of smell.
✓. Voluntarily participates, provides informed consent, and is able to complete questionnaires and follow-up visits.
Exclusion criteria
✕. Previous nasal surgery within 6 months before screening that altered lateral wall structure and precludes polyp assessment.
✕. Allergy to corticosteroids or any component of the fully degradable sinus drug-eluting stent.
What they're measuring
1
Part A: Median Time to Early Polyp/Edema Recurrence Within 6 Months
Timeframe: From treatment initiation up to 6 months.
2
Part A: Incidence Rate of Early Polyp/Edema Recurrence at Each Visit
Timeframe: Assessed at Week 2, Week 4, Week 8, Week 12, and Month 6.
3
Part B:Lund-Kennedy Endoscopic Score and Change from Baseline
Timeframe: Assessed at Week 2, Week 4, Week 8, Week 12, and Month 6.
✕. Recent use of steroids (30-day washout for parenteral, 14-day for oral, budesonide drops/irrigation, nebulized), immunosuppressants/biologics (within 5 terminal half-lives), or leukotriene antagonists/modulators prior to baseline.
✕. Recent acute sinusitis episode.
✕. Physical obstruction preventing access to any ethmoid sinus for stent delivery.
