Trial Outcomes & Findings for Safety and Effectiveness of an Auricular Spray (NCT NCT06085443)

NCT ID: NCT06085443

Last Updated: 2025-07-10

Results Overview

To confirm the safety of the device by clinical examination by ENT specialist and scoring of the irritation of the ear canal at Day90 in comparison with basal scoring of irritation at Day0 such as: * 0: no irritation, * 1: slight irritation (located slight erythema and/or dryness), * 2: moderate irritation (clear erythema or dryness which may be visible on the whole treated area), * 3: severe irritation (serious erythema with potential oedema and/or scar).

SECONDARY outcome

Timeframe: Day0 and Day90

To confirm the efficacy/performance of the device for the prevention of ear obstruction in comparison to baseline (Day0) and between groups using the scoring of the obstruction of ear canal by the Investigator: 0: no obstruction - normal and/or no significant presence of cerumen in the ear canal. The membrane is clearly visible. 1. \<25% minimal, very little and mostly insignificant impacted cerumen. The tympanic membrane is visible, but with still a little bit cerumen. 2. 25-50% mild, some excessive impacted cerumen causing partial occlusion of the ear canal. The tympanic membrane is not entirely visible, quite difficult to see. 3. 50-75% moderate, moderate and excessive impacted cerumen causing partial occlusion of the ear canal. Partial to very little of the tympanic membrane is visible. 4. 75-100% severe, severe and excessive impacted cerumen causing partial or complete occlusion of the ear canal. Little if any of the tympanic membrane is visible.

SECONDARY outcome

Timeframe: Day0 and Day90

Secondary aims: EFFICACY/PERFORMANCE PREVENTION for investigational device and for control group, in comparison to the baseline (Day0) using an audiogram (only for subjects more than 6). Hearing function was assessed in patients on day 0 (D0) and day 90 (D90). The mean difference in hearing function (D90 - D0), expressed in decibels (dB), was reported in a data table. A mean difference greater than +5 dB is considered a gain in hearing function, while a mean difference less than -5 dB is considered a loss in hearing function. A difference in hearing function within the range \[-5 dB; +5 dB\] is considered to indicate no effect on hearing function.
