Trial Outcomes & Findings for Safety and Efficacy of EXE844 Otic Suspension in Otitis Media at Time of Tympanostomy Tube Insertion (OMTT) - Study 2 (NCT NCT02436304)

NCT ID: NCT02436304

Last Updated: 2018-07-02

Results Overview

Sustained clinical cure was defined as the absence of otorrhea in the study ear at Day 8 (end of treatment (EOT)) per the Investigator assessment. Participants were considered a treatment failure if, at any time during the course of the study, an alternative therapy was initiated to treat the post-surgical infection. All participants who had missing or indeterminate outcomes were considered a failure (same as baseline observation carried forward).

SECONDARY outcome

Timeframe: Day 14

Population: This analysis population includes all ITT participants who were culture-positive at Day 1 in at least 1 ear (Microbiological Intent-to-Treat (MITT) analysis set)

Microbiological success was attained if all pretherapy bacteria were absent in the study ear for the test-of-cure (TOC) specimen, which was presumed a success for subjects with no otorrhea at Day 14. Participants were considered a treatment failure if, at any time during the course of the study, an alternative therapy was initiated to treat the post-surgical infection. All participants who had missing or indeterminate outcomes were considered a failure (same as baseline observation carried forward).

SECONDARY outcome

Timeframe: Up to Day 14

Population: ITT analysis set

The time to cessation of otorrhea in the enrolled ear(s) was calculated as the number of days from the day of surgery to the absence of otorrhea (ie, no discharge) as reported by the parent/caregiver. Participants were considered a treatment failure if, at any time during the course of the study, an alternative therapy was initiated to treat the post-surgical infection. All participants who had missing or indeterminate outcomes were considered a failure (same as baseline observation carried forward).
