Details and patient eligibility

About

The goal of this clinical trial is to assess the safety of intracochlear application of VSF1.01 for the reduction of cochlear implant surgery related trauma in patients with profound hearing loss with or without non-functional residual hearing in low frequencies and cochlear implantation.

The main questions it aims to answer are:

Primary objective:

Safety of intracochlear application of VSF1.01 in patients receiving cochlear implantation

Secondary objectives:

Effectiveness on

neural responses of auditory nerve
speech understanding
hearing thresholds
electrode impedances

During cochlear implant operation, patients receive as adjuvant treatment intracochlear VSF1.01 prior to insertion of the electrode array.

Cochlear implantation is conducted according to the clinical standard at the investigational site.
