| Primary | Change in Pure Tone Audiometry PTA (dB) (Average of the Hearing Threshold of the 3 Contiguous Most Affected Hearing Frequencies in dB as Identified at Study Entry) From Baseline to the End of Treatment Visit (Day 28 ± 3). | Pure Tone Audiometry PTA (dB) thresholds were determined for each ear at 0.25, 0.5, 1, 2, 3, 4, 6, and 8 kHz for air conduction and 0.5, 1, 2, 3, 4 kHz for bone conduction.
Pure Tone Audiometry PTA (dB) is an hearing test used to identify hearing threshold levels of an individual and enabling determination of the degree hearing loss. A clinically significative improvement is defined as a decrease of at least 10 dB of hearing threshold. |

| Secondary | Change in Speech Discrimination Threshold From Baseline to Day 28 | The Speech recognition threshold (SRT) (dB) is the minimum hearing level at which an individual can correctly recognize 50% of speech material; the more severe the hearing loss is, the higher SRT is. Spondaic words are the usual and recommended test material for the speech recognition threshold; spondaic words are two-syllable words with equal stress on both syllables (eg, birthday). Per the American Speech-Language-Hearing Association (ASHA) guidelines, subjects were familiarized with the spondaic words prior to the test; they listened to the list of words and indicated if any were unfamiliar. These words could then be eliminated from the list. | Day 28 | |
