Trial Outcomes & Findings for Post-market Clinical Follow-up of a Magnetic Bone Conduction Implant (Cochlear Baha Attract System) (NCT NCT02022085)

NCT ID: NCT02022085

Last Updated: 2018-10-12

Results Overview

The change of hearing performance with the Baha Attract System (aided) at 6, 12 and 24 months from the unaided hearing performance before surgery; measured as free-field hearing tests: Threshold audiometry PTA4 (mean of 500, 1000, 2000 and 4000 Hz). The units reported for PTA4 are decibels (dB). As such, a lower or more negative score is more desirable and reflects the ability to hear softer sounds.

Baha Attract System
This transcutaneous solution is based on a magnet coupling using magnets on both side of the skin; * One implant magnet * One external magnet on which a sound processor is attached, i.e. the Sound Processor magnet (SP magnet) Baha Attract System: The Cochlear Baha Attract System incorporates both implantable and external parts. The implantable parts include the BI300 Implant and the BIM400 Implant Magnet, which is intended to be fixated to the BI300 Implant. The external parts include the Sound Processor Magnet (SP Magnet), which, together with the Implant Magnet, constitute the transcutaneous coupling. The SP Magnet incorporates a soft material (Soft pad) at the tissue facing surface that is designed to distribute the pressure over the skin. The Baha Sound Processor attaches to the SP Magnet via a snap coupling.

SECONDARY outcome

Timeframe: Baseline (unaided) before surgery, 6, 12 and 24 months after surgery

Population: Intention-to-Treat (ITT) population; includes all patient who received the surgical intervention. Adaptive Speech in Noise analysis excluded subjects from Birmingham and Manchester clinics due to incorrect set up.

The change of hearing performance with the Baha Attract System compared to the pre-operative unaided situation; Adaptive speech recognition in noise measured as signal to noise ratio The adaptive speech test in noise was conducted using validated lists of phonetically balanced sentences, with speech presented from the front (0 degrees azimuth) and noise from the back (180 degrees azimuth). The noise was kept constant at 65 dB SPL, and the speech was adapted in 2 dB steps to establish the speech-to-noise ratio (SNR) providing a 50% level of understanding. A ratio of 1 reflects the ability to correctly hear sentences at 65 dB, in the presence of 65 dB background noise. A lower ratio than 1 reflects the ability to correctly hear sentences below 65 dB. A ratio higher than 1 reflects the ability to correctly hear sentences presented above 65 dB. Manchester and Birmingham are excluded from this analysis due to incorrect set up.

This transcutaneous solution is based on a magnet coupling using magnets on both side of the skin; * One implant magnet * One external magnet on which a sound processor is attached, i.e. the Sound Processor magnet (SP magnet) Baha Attract System: The Cochlear Baha Attract System incorporates both implantable and external parts. The implantable parts include the BI300 Implant and the BIM400 Implant Magnet, which is intended to be fixated to the BI300 Implant. The external parts include the Sound Processor Magnet (SP Magnet), which, together with the Implant Magnet, constitute the transcutaneous coupling. The SP Magnet incorporates a soft material (Soft pad) at the tissue facing surface that is designed to distribute the pressure over the skin. The Baha Sound Processor attaches to the SP Magnet via a snap coupling.

Population: Intention-to-Treat (ITT) population; includes all patients who received the surgical intervention.

Change of health status and health related quality of life using the generic quality of life scale Health Utilities Index (HUI3) when wearing Baha Attract System compared to the pre-operative unaided situation. A health utility value of 1.00 indicates perfect health while a score of 0.00 indicates death. The change from unaided to aided hearing is presented. A positive value indicates an improved quality of life, a negative value indicates impaired quality of life. HUI score of 1 (maximum) describes a state of perfect health. HUI score of 0 describes a state of dead. A negative score of Comprehensive Health State describes a state worse than dead.

This transcutaneous solution is based on a magnet coupling using magnets on both side of the skin; * One implant magnet * One external magnet on which a sound processor is attached, i.e. the Sound Processor magnet (SP magnet) Baha Attract System: The Cochlear Baha Attract System incorporates both implantable and external parts. The implantable parts include the BI300 Implant and the BIM400 Implant Magnet, which is intended to be fixated to the BI300 Implant. The external parts include the Sound Processor Magnet (SP Magnet), which, together with the Implant Magnet, constitute the transcutaneous coupling. The SP Magnet incorporates a soft material (Soft pad) at the tissue facing surface that is designed to distribute the pressure over the skin. The Baha Sound Processor attaches to the SP Magnet via a snap coupling.
