The purpose of this study is to evaluate a single application of AL-60371/AL-817 Otic Suspension relative to ototopical CIPRODEX for microbiological success at Day 8 and time to cessation of otorrhea.

Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Investigator)

Primary Outcome Measures:
  • Proportion of Subjects With Sustained Clinical Cure at Day 3 Visit [ Time Frame: Day 3 ] [ Designated as safety issue: No ]
    A sustained clinical cure at Day 3 was attained if otorrhea was absent at the Day 3 visit and continued to be absent through the last study visit (Day 8 or Early Exit). Proportion of subjects is reported as a percentage.

Secondary Outcome Measures:
  • Proportion of Subjects With Microbiological Success at the Day 8 Visit [ Time Frame: Day 8 ] [ Designated as safety issue: No ]
    Microbiological success was attained if all pre-therapy bacteria were absent in the Day 8 specimen. In a subject with no otorrhea at Day 8, eradication of pre-therapy bacteria was presumed and the subject was considered a microbiological success.

  • Median Time (in Days) to Cessation of Otorrhea [ Time Frame: Time to event, up to Day 8 ] [ Designated as safety issue: No ]
    Median time (in days) to the cessation of otorrhea (ie, otorrhea was absent) was calculated as the number of days from the Day 1 (Visit 1) to the absence of otorrhea in the affected ear(s) as recorded by the parent/guardian via the twice-daily diary. Cessation of otorrhea was defined as ending on the first day that otorrhea was absent from the affected ear(s) and remained absent for any/all subsequent diary entries.

Enrollment: 84
Study Start Date: December 2013
Study Completion Date: August 2014
Primary Completion Date: August 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: AL-60371/AL-817
AL-60371/AL-817 otic suspension, 200 μL in affected ear(s) through tympanostomy tube on Day 1 (Visit 1)
Drug: AL-60371/AL-817 otic suspension
Active Comparator: CIPRODEX
Ciprofloxacin 0.3%/dexamethasone 0.1% otic suspension, 4 drops in affected ear(s) twice daily through tympanostomy tube for 7 days
Drug: Ciprofloxacin 0.3%/dexamethasone 0.1% otic suspension

Detailed Description:

The results at the time of the interim analysis met the futility criteria and the study was subsequently stopped.
