Beknopte samenvatting
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.

Actieve comparatorthe efficacy and safety of the stent when used immediately after functional endoscopic sinus surgery
the fully degradable sinus stent
The intervention is a fully degradable sinus drug-eluting stent system. The stent will be implanted into the bilateral targeted sinus cavities of the participants. Part A Cohort: The stent is placed immediately following Functional Endoscopic Sinus Surgery (FESS). Part B Cohort: The stent is placed when participants are assessed to be in a state of early postoperative recurrence.
intranasal corticosteroids
This is the intervention for the drug comparator group in Part A. Participants will administer a prescribed dose of intranasal corticosteroid spray daily via bilateral nasal application according to the protocol.

the fully degradable sinus stent
The intervention is a fully degradable sinus drug-eluting stent system. The stent will be implanted into the bilateral targeted sinus cavities of the participants. Part A Cohort: The stent is placed immediately following Functional Endoscopic Sinus Surgery (FESS). Part B Cohort: The stent is placed when participants are assessed to be in a state of early postoperative recurrence.
Orale corticosteroïden
This is the intervention for the drug comparator group in Part B. Participants will receive a prescribed course of oral corticosteroids as needed based on clinical assessment and upon signs of early postoperative recurrence, in accordance with the study protocol.
