Clinical Trial Summary

The purpose of this study was to demonstrate superiority of AL-60371 relative to Vehicle based on clinical cures at test-of-cure (TOC) for the treatment of acute otitis externa (AOE).

Description:

Participants or legal guardians completed a telephone diary twice daily to record assessments of ear pain, ear medication use, and impact of ear pain on sleep and other daily activities.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Proportion of Patients With Clinical Cures at the Day 11 (TOC) Visit	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.	Day 11	No
Secondary	Proportion of Patients With Microbiological Successes at the Day 11 (TOC) Visit	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.	Day 11	No
Secondary	Median Time (in Days) to Cessation of Ear Pain as Reported by the Patient or Parent/Legal Guadian Via the Telephone Diary	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.	Time to event (Day 1 to Day 11)	No
