Clinical Trial Summary

Primary objective of the study is to assess the efficacy of SENS-401 on hearing loss in comparison to placebo at the end of the 4-week treatment period


Description:

Patients will receive the study drug (SENS-401 or placebo) in the form of tablets by mouth, twice a day (3 tablets in the morning and 3 tablets in the evening), during the first 4 weeks after randomization. SENS-401 is an investigational medicinal product. It belongs to a family of drugs known as "5 HT3 antagonist".

Outcome

Type Measure Description Time frame Safety issue
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.

Day 84
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
