- Number of Participants With Clinical Cure of AOE [ Time Frame: 7 days after the completion of therapy; at Day 15 (+/- 1 day) ]The primary efficacy endpoint was the clinical cure of AOE, defined as the proportion of subjects with a clinical AOE score of 0 at the TOC Visit. Subjects with AOE in both ears were considered to have achieved clinical cure of AOE if the clinical AOE score was 0 for both ears. The clinical AOE score was defined as the sum of scores for inflammation and edema (0=absent, 1=mild, 2=moderate, 3=severe) and tenderness and otorrhea (0=absent, 1=present).
- Number of Participants With Microbiological Cure (MC) [ Time Frame: 7 days after the completion of therapy; at Day 15 (+/- 1 day) ]The secondary efficacy endpoint was the microbiological cure of AOE, defined as the proportion of subjects with microbiological cure at the TOC Visit. Subjects with AOE in both ears were considered to have achieved microbiological cure if microbiological cure was achieved in both ears.
