What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The Number of DVD at Week 12 (Defined as the 4-week [28 Days] Interval From Week 9 Through Week 12).	The number of DVDs at Week 12 (defined as the 4-week [28 days] interval from Week 9 through Week 12) was compared between OTO-104 and placebo. Week 12 = 12 weeks after dosing at the Baseline visit. Baseline occurred at the end of lead-in and no intervention was administered during lead-in.	Week 12 (3 months)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Audiometry - Shift in Air-Bone Gap at 1000 Hz From Baseline to Week 12 (Month 3)	The number of subjects with a change in air-bone gap from Baseline to Week 12 (Month 3) from no impairment at baseline (<= 10 dB) to impairment at Month 3 (>10 dB) when measured at 1000 Hz.	Week 12 (Month 3)
Audiometry - Shift in Air-Bone Gap at 2000 Hz From Baseline to Week 12 (Month 3)	The number of subjects with a change in air-bone gap from Baseline to Week 12 (Month 3) from no impairment at baseline (<= 10 dB) to impairment at Month 3 (>10 dB) when measured at 2000 Hz.	Week 12 (Month 3)
Effect of Vertigo on Daily Activities - Number of Days Sick at Home or Bedridden at Week 12 (Month 3)	Questionnaire - subjects were instructed to record the effect on their daily activities of their total vertigo experienced that day using a 5-point scoring system: 0 = normal activity; = slight limitation; = moderate limitation; = sick at home; = bed ridden	3 months
Otoscopic Examination - Tympanic Membrane Perforation at Week 12 (Month 3)	Otoscopic examinations were conducted at each visit. It was considered important to understand if the tympanic perforation that resulted from the IT injection at the Baseline visit persisted at the end of study visit (Week 12 [Month 3]).	3 months
Audiometry - Shift in Air-Bone Gap at 500 Hz From Baseline to Week 12 (Month 3)	The number of subjects with a change in air-bone gap from Baseline to Week 12 (Month 3) from no impairment at baseline (<= 10 dB) to impairment at Month 3 (>10 dB) when measured at 500 Hz.	3 months
