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).

Condition Intervention Phase
Acute Otitis Externa
Drug: AL-60371, 0.3% otic suspension
Drug: AL-60371 Vehicle
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Official Title: Safety and Efficacy Evaluation of Topical AL-60371 Otic Suspension, 0.3% in the Treatment of Acute Otitis Externa

Further study details as provided by Alcon Research:

Primary Outcome Measures:
  • Proportion of Patients With Clinical Cures at the Day 11 (TOC) Visit [ Time Frame: Day 11 ]
    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 Measures:
  • Proportion of Patients With Microbiological Successes at the Day 11 (TOC) Visit [ Time Frame: Day 11 ]
    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.

  • Median Time (in Days) to Cessation of Ear Pain as Reported by the Patient or Parent/Legal Guadian Via the Telephone Diary [ Time Frame: Time to event (Day 1 to Day 11) ]
    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.

Detailed 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.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • At least 6 months of age.
  • Clinical diagnosis of acute otitis externa (AOE) based on clinical observation and of presumed bacterial origin in at least one ear.
  • Combined numerical score of ≥4 in at least one affected ear at the Day 1 exam for tenderness, erythema, and edema.
  • Agree to refrain from water immersion of the ears during the conduct of the entire study.
  • Other protocol-defined inclusion criteria may apply.

Exclusion Criteria:

  • Duration of signs or symptoms of AOE greater than 28 days in the affected ear(s) as reported by patient or parent/guardian.
  • Presence of a tympanostomy tube or perforated tympanic membrane in the affected ear(s).
  • Clinically diagnosed otic disease other than AOE (eg, malignant otitis externa) in the affected ear(s).
  • Known or suspected ear infection of yeast, fungal or mycobacterial origin in the affected ear(s).
  • Prior otologic surgery within 6 months of study entry in the affected ear(s).
  • Known or suspected allergy or hypersensitivity to quinolones or other ingredients present in the medications to be used in the study.
