NCT06545175

Brief Summary

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

  1. 1.neural responses of auditory nerve
  2. 2.speech understanding
  3. 3.hearing thresholds
  4. 4.electrode impedances

EXPERIMENTAL
Drug: Intracochlear application of VSF1.01

Interventions

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

  • hysterectomy or uterine agenesis or
  • ≥ 50 years and in postmenopausal state \> 1 year or
  • Women of childbearing potential:
  • who are practicing sexual abstinence (periodic abstinence and withdrawal are not acceptable) or
  • who have sexual relationships with female partners only and/or with sterile male partners or
  • who are sexually active with fertile male partner, have a negative pregnancy test during screening and agree to use reliable methods of contraception from the time of screening until end of the clinical trial.
  • Signed written informed consent from subjects capable of understanding all information and to give full informed consent
  • Functional deaf patients (profound hearing loss with or without non-functional residual hearing in the low frequencies i.e. 125 Hz: 45 dB - 95 dB; 250 Hz: 50 dB - 105 dB; 500 Hz: 55 dB - 110 dB; 750 Hz and higher: 65 dB or below) that are candidates for cochlear implantation

You may not qualify if:
