Brief Summary

The RESOLVE Study is a randomized controlled trial with the S8 Sinus Implant in 100 chronic sinusitis patients with recurrent nasal polyps.

Detailed Description

RESOLVE is a randomized (1:1), sham-controlled, parallel group, double-blind multicenter study in 100 chronic sinusitis patients who had prior endoscopic sinus surgery and presented with recurrent nasal polyps. The objective of the study was to assess the safety and efficacy of the S8 Sinus Implant, a steroid-eluting sinus implant, consisting of a bioabsorbable self-expanding sinus implant coated with 1350 mcg of mometasone furoate (MF) and a single-use delivery system. Implant is placed in-office in the ethmoid sinus under local anesthesia. The coating on the S8 implant provides controlled release of MF to the sinus mucosa over 90 days, with the majority of drug released within 60 days.

Primary Outcome Measures
NameTimeMethod
Nasal Obstruction/Congestion Score90 days

Nasal Obstruction by patients using a paper questionnaire on a scale from 0 (no problem) to 5 (problem as bad as it can be). Negative values for change from baseline represented reduction (improvement) in

Bilateral Polyp Grade90 days

Polyp grade was determined by a panel of 3 independent sinus surgeons based on a centralized, blinded videoendoscopy review. Each sinus was graded from 0 (no visible polyps) to 4 (nasal polyps completely obstructing nasal cavity) and then the left and right values were added to obtain a total bilateral polyp grade, ranging from 0 to 8. Negative values for change from baseline represented reduction (improvement) in bilateral polyp grade.

Secondary Outcome Measures
NameTimeMethod
Ethmoid Sinus Obstruction90 days

Percentage of the ethmoid sinus volume obstructed by scarring, polyps, or edema on endoscopy, as determined by a panel of 3 independent sinus surgeons based on a centralized, blinded videoendoscopy review using a 100-mm visual analogue scale (VAS), ranging from 0 (absence of obstruction) to 100 (complete obstruction). Negative values for change from baseline represented reduction (improvement) in ethmoid sinus obstruction.

Bilateral Polyp Grade90 days, 6 months

Polyps were graded by clinical investigators on a scale from 0 (no visible polyps) to 4 (nasal polyps completely obstructing nasal cavity) and then the left and right values were added to obtain a total bilateral polyp grade, ranging from 0 to 8. Negative values for change from baseline indicate reduction (improvement) in nasal polyps.

Nasal Obstruction Symptom Evaluation (NOSE) Score6 months

NOSE scale is a validated symptom scoring instrument consisting of 5 questions each scored by patients on a 5-point Likert scale from 0 (not a problem) to 4 (severe problem), then multiplied by 5 and resulting in a total score ranging from 0 to 100. Negative values for change from baseline represented reduction (improvement) in NOSE score.

Percentage of Patients Indicated for Revision Endoscopic Sinus Surgery (RESS)90 days, 6 months

To be indicated for RESS, the following criteria had to be met:

* Continued to use topical intranasal steroids daily;

* Continued to complain of at least 2 symptoms of chronic sinusitis despite ongoing topical intranasal steroid use

* Needed or had received at least 1 course of aggressive steroid therapy or had refused such therapy due to intolerance/side effects; and

* Had endoscopic evidence of persisting ethmoid sinus obstruction (bilateral polyp grade \>=2 on at least one side)
