Details and patient eligibility

About

The purpose of the study is to demonstrate the clinical therapeutic non-inferiority of EXL CDOS to commercially available Ciprofloxacin 0.3% and Dexamethasone 0.1% Sterile Otic Suspension (Ciprodex®, Alcon) in the treatment of acute otitis externa (AOE) when administered twice daily for 7 days.

Full description

This was a Phase 3, multicenter, randomized, double-blind, active-controlled, parallel-group study in adults and children (age 6 months and older) with a diagnosis of AOE with a 2-day screening period followed by a 2-week participation period. Subjects were administered study drug, EXL CDOS or RLD, 4 drops in the affected ear(s) BID for 7 days. The primary endpoint, the proportion of subjects with a clinical AOE score of 0, was measured at the TOC Visit on Day 15.
