About this trial
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. neural responses of auditory nerve 2. speech understanding 3. hearing thresholds 4. 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.

Treatment groups
Trial outcomes
Primary outcomes
Rate and severity of (serious) adverse events
Recording and documentation of number and severity of (serious) adverse events
Secondary outcomes
Evaluation of eCAP growth function
Assessment of effectiveness on neural responses of auditory nerve by measuring electrically evoked compound action potential (eCAP; eCAP growth function)
Evaluation of speech perception
Assessment of effectiveness on speech understanding by measuring speech perception (in quiet and in noise) by HSM 10dB SNR/5dB SNR, FBM, OLSA 50%
Measurement of air and bone conduction
Assessment of effectiveness on hearing thresholds by measuring air and bone conduction from 125 Hz - 16,000 Hz by pure tone audiometry
Measurement of impedance levels
Assessment of effectiveness on electrode impedances by determination of impedance levels (as measure to rule out pathological levels and as part of clinical routine)
