Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of Subjects Considered a Clinical Cure at Day 15 (Intent-to-treat Analysis Set) | Day 15 (two weeks from dosing) | Clinical Signs (edema, erythema, otorrhea and otalgia) all had a score of 0 at Day 15. Each sign was graded as follows: None = 0 Mild = 1 Moderate = 2 Severe = 3 |
