Trial Outcomes & Findings for Safety and Efficacy Evaluation of Topical AL-60371 Otic Suspension, 0.3% in the Treatment of Acute Otitis Externa (NCT NCT01535560)

NCT ID: NCT01535560

Last Updated: 2013-12-10

Results Overview

An otoscopic exam was conducted by the physician. Clinical cure was considered attained if the sum of the numerical scores of the 3 signs and symptoms of AOE (tenderness, erythema, and edema) was 0 at Day 11. Proportion of patients is reported as percentage of participants.

PRIMARY outcome

Timeframe: Day 11

Population: This reporting group includes the pathogen positive patients of the intent-to-treat (ITT) analysis set, ie. all patients who received study drug and were pathogen positive in the study ear at baseline.

An otoscopic exam was conducted by the physician. Clinical cure was considered attained if the sum of the numerical scores of the 3 signs and symptoms of AOE (tenderness, erythema, and edema) was 0 at Day 11. Proportion of patients is reported as percentage of participants.

SECONDARY outcome

Timeframe: Day 11

Population: This reporting group includes the pathogen positive patients of the intent-to-treat (ITT) analysis set, ie. all patients who received study drug and were pathogen positive in the study ear at baseline.

Microbiological success was considered attained if all pre-therapy bacteria were absent from the exit otic specimen. The presence of fungi and/or yeast was not considered in the determination of microbiological success. Proportion of patients is reported as a percentage of participants.

SECONDARY outcome

Timeframe: Time to event (Day 1 to Day 11)

Population: This reporting group includes the pathogen positive patients of the intent-to-treat (ITT) analysis set, ie. all patients who received study drug and were pathogen positive in the study ear at baseline, minus missing responses.

Cessation of ear pain was defined as occurring the first time point that ear pain was absent (morning or evening) and did not reoccur in any subsequent diary entries.
