Conditions: Chronic Sinusitis
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 5
Healthy volunteers: no

Brief summary:
The purpose of this study was to assess the safety and performance of the steroid-releasing S8 Sinus Implant when used in post-sinus surgery patients who presented with recurrent sinus obstruction.

Detailed description:
The S8 PK study was a single-center, open label study treating 5 adult (18 years or older) patients diagnosed with chronic sinusitis, who had undergone prior bilateral total ethmoidectomy and later presented with recurrent nasal obstruction/congestion symptoms and bilateral ethmoid polyposis. The S8 PK study assessed the safety, implant delivery to the ethmoid sinus, and systemic exposure to mometasone furoate (MF) by measuring plasma MF and cortisol concentrations through 30 days post-procedure.

Arms:
arm 1: Bilateral in-office placement of the S8 Sinus Implant (mometasone furoate, 1350 mcg) in the ethmoid sinuses

Interventions: intervention 1: S8 Sinus Implant (mometasone furoate, 1350 mcg)
Intervention descriptions: intervention 1: Bioabsorbable sinus implant with 1350 mcg of mometasone furoate released over 90 days
