Randomized Cohort: Difference in Patency Grade of FSO Primary · 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 easi

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

Randomized Cohort: Estimated Frontal Sinus Ostia (FSO) Diameter Secondary · 30 days

The smallest and largest diameters of the FSO determined by an independent, blinded sinus surgeon based on the centralized video-endoscopy review. FSO diameter estimated endoscopically by probing with a 3-mm olive-shaped frontal sinus suction tip and reported in mm.

PK Cohort: Total Sino-Nasal Outcomes Test Score (SNOT-22) Secondary · Baseline, Day 14 and Day 30

SNOT-22 is a validated, disease-specific, symptom-scoring instrument consisting of 22 questions, each scored by patient on a 6-point scale as follows: 0: No problem; 1: Very mild problem; 2: Mild or slight problem; 3: Moderate problem; 4: Severe problem; 5: Problem as bad as it can be. Sum of all 22 questions constitutes the total SNOT-22 score with a maximum total score equal to 110.
