Brief Summary:
A randomized controlled trial

Condition or disease Intervention/treatment Phase
Chronic Sinusitis Device: PROPEL Mini Sinus Implant Procedure: Balloon Sinus Dilation Alone Not Applicable

Detailed Description:
This is a prospective, randomized, single-blind, intra-patient controlled, multicenter trial with 50 subjects enrolled at up to 15 sites across the United States. Study subjects undergo implant placement on one side following in-office balloon dilation, while the contralateral side undergoes balloon dilation only and serves as a control.

Arm Intervention/treatment
Experimental: PROPEL Mini Sinus Implant
Placement of the Propel Mini Sinus Implant in one frontal sinus ostia (FSO) assigned to the treatment group following in-office balloon dilation
Device: PROPEL Mini Sinus Implant
Sinus implant with 370 mcg of mometasone furoate released over 30 days
Other Name: PROPEL Mini

Procedure: Balloon Sinus Dilation Alone
Active Comparator: Balloon Sinus Dilation Alone
In-office balloon dilation of the contralateral frontal sinus ostia (FSO) without implant placement
Procedure: Balloon Sinus Dilation Alone

Primary Outcome Measures :
  1. Patency Rate [ Time Frame: Day 30 ]
    Patency of the frontal recess/frontal sinus ostia (FSO) was evaluated on a 3-point grading scale from 0 to 2, with 0=Patent, 1=Restenosed/partially occluded, and 2=Occluded. The percentage of sinuses with patency grade 0 and 1 was used to calculate the patency rate.

Secondary Outcome Measures :
  1. Inflammation Score [ Time Frame: Day 30 ]
    Inflammation visual analog scale (VAS) from 0 (no visible inflammation) to 100 (severe inflammation, involving significant and extensive erythema and edema and/or hypertrophy and/or polypoid changes)

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria

  • Patient has provided written informed consent using a form approved by the reviewing IRB.
  • Patient is 18 years of age or older.
  • Patient is willing and able to comply with protocol requirements.
  • Patient has CRS defined as sinonasal inflammation persisting for more than 12 weeks and complains of at least 2 of the 4 following symptoms: nasal blockage/obstruction/congestion, nasal blockage/obstruction/congestion, nasal discharge (anterior/posterior), facial pain/pressure, reduction/loss of smell
  • CRS diagnosis confirmed by CT scan within 3 months prior to enrollment
  • Bilateral frontal sinusitis confirmed by Lund-Mackay score of ≥1 on each side
  • Post-endoscopic sinus surgery, patient has bilateral obstruction of the frontal sinus ostia by scarring and/or polypoid edema.
  • Patient is a candidate for an in-office balloon dilation procedure.
  • In the opinion of the investigator, treatment with the Propel Mini Sinus Implant as an adjunct to balloon sinus dilation is technically feasible and clinically indicated in the frontal sinus ostia.

Exclusion Criteria:

  • Expanded amount of ethmoid sinonasal polyps extending beyond the middle meatus of grade 3 or 4 unless reduced prior to randomization in the study.
  • Oral-steroid dependent condition such as chronic obstructive pulmonary disease (COPD) or other conditions.
  • Known history of allergy or intolerance to corticosteroids or mometasone furoate.
  • Clinical evidence of acute bacterial sinusitis or invasive fungal sinusitis.
  • Active viral illness (e.g., flu, shingles).
  • Clinical evidence of disease or condition expected to compromise survival or ability to complete follow-up assessments through Day 180 post-procedure.
  • Currently participating in another clinical trial.
