简要总结

The objective of the ASCEND Study is to assess the safety, performance, and efficacy of the Intersect ENT UP Drug-Coated Device when used in chronic rhinosinusitis (CRS) patients undergoing balloon dilation of frontal sinus ostia (FSO)

详细描述

This is a prospective, multicenter study enrolling two consecutive cohorts:

PK cohort (N=5): A non-randomized cohort to assess the systemic safety and performance of the UP Drug-Coated Device for in-office bilateral dilation of the FSO (2 inflations in each FSO for a total of 4 inflations per device). Subsequently, the UP Drug-Coated Device may be used to dilate any sphenoid or maxillary sinuses.

Randomized cohort (N=70): A randomized, intra-patient controlled, double-blind cohort of 70 subjects to assess the safety and efficacy of the UP Drug-Coated Device used for in-office dilation of the FSO. The FSO randomized to the treatment (Treatment) will undergo dilation using the UP Drug-Coated Device (2 inflations per device) while the contralateral FSO (Control) will be dilated with a UP Control Device (2 inflations per device).

入选标准

  • Confirmed diagnosis of CRS per the 2016, "International Consensus Statement on Allergy and Rhinology" definition.
  • Bilateral disease in the frontal sinuses (Lund-Mackay score ≥ 1 on each side) on CT scan within 30 days prior to enrollment in the PK cohort and prior to randomization in the randomized cohort.
  • Patient has bilateral obstruction of the frontal recess/FSO due to scarring and/or polypoid edema confirmed on endoscopy (patency grade of 0 or 1 for each FSO).
  • Balloon dilation of the FSO judged to be feasible and medically appropriate.
  • Patient has had prior ESS (> 30 days with a healed mucosa) including bilateral ethmoidectomy (anterior or total) and uncinectomy for better visualization of the FSO.
  • Balloon dilation of the FSO with a 6 mm balloon is judged to be feasible (use light-assisted or image-guided instrument such as a frontal sinus seeker tip to confirm access of each FSO) and medically appropriate.

排除标准

  • Expanded amount of ethmoid polyposis (grade > 2 PK cohort, grade ≥ 2 randomized cohort).
  • Complications from prior ESS or balloon dilation procedure (e.g., cerebrospinal fluid leak or injury to the skull base).
  • History of aspirin exacerbated respiratory disease (AERD).
  • Current smokers.
  • History of allergy or intolerance to mometasone furoate.
  • Oral-steroid dependent condition.
  • Evidence of acute rhinosinusitis, invasive fungal sinusitis or another disease or condition expected to compromise survival or ability to complete assessments during the 30-day follow-up period in the PK cohort and druing the 60-day follow-up period in the randomized cohort.
  • Use of parenteral and injected steroids (e.g., Kenalog) 30 days prior to the baseline procedure.
  • Use of oral steroids, budesonide or other sinus steroid irrigations/rinses or drops, nebulized steroids administered nasally 14 days prior to screening in the PK cohort and prior to baseline in the randomized cohort.
  • Glaucoma or posterior subcapsular cataract.

结局指标

主要结局

Randomized Cohort: Difference in Patency Grade of FSO

时间窗: 30 days

Difference in the patency grade of the FSO between treatment sides at Day 30, as determined by an independent, blinded sinus surgeon based on the centralized video-endoscopy review. Patency of the FSO assessed endoscopically by probing with a 3-mm olive-shaped frontal sinus suction tip ("suction tip") and graded on a 5-point scale as follows - 0: Occluded (no opening visible); 1: Significantly stenosed (not occluded, but unable to pass the 3-mm suction tip); 2: Moderately stenosed (able to easily pass the 3-mm suction tip with no additional space around it); 3: Minimally stenosed (able to easily pass the 3-mm suction tip with additional 1-2 mm space around it); 4: Completely patent (able to easily pass the 3-mm suction tip with additional \>2 mm space around it)

The Number of Participants in the PK Cohort With Successful Dilation of Attempted FSO at Baseline

时间窗: Baseline

Successful dilation of attempted FSO using the Drug-Coated Device with no unanticipated serious adverse device effects. A successful dilation of the FSO is defined as insertion of the UP Drug-Coated Device into the targeted FSO followed by 2 consecutive, complete inflations of the balloon.

次要结局

  • Randomized Cohort: Estimated Frontal Sinus Ostia (FSO) Diameter(30 days)
  • PK Cohort: Estimated Largest Frontal Sinus Ostia (FSO) Diameter(Baseline to 30 days)
  • PK Cohort: Estimated Smallest Frontal Sinus Ostia (FSO) Diameter(Baseline to 30 days)
  • PK Cohort: Total Sino-Nasal Outcomes Test Score (SNOT-22)(Baseline, Day 14 and Day 30)
