Recruiting NA Sensorineural Hearing Loss

New treatment option for Sensorineural Hearing Loss

Official title Immunity After Cochlear Implantation and Perilymph Molecular Profiles in Sensorineural Hearing Loss

ClinicalTrials.gov ID: NCT05670158

What this study is testing

What is Blood sampling?

Blood sampling is an investigational medicine, given as a treatment applied to the skin, being studied as a potential treatment for sensorineural hearing loss.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
Many patients receiving cochlear implant (CI) have some residual hearing prior to implantation surgery. However, approximately one third of them will lose it in next 6 months after cochlear implantation.
  • Time commitment: about 12 months

  • Contraindication to surgery detected during the preoperative assessment
  • Pre-implantation cochlear assessment unfavorable to the implantation surgery
  • Absence of residual hearing shown by preoperative audiometry
  • History of bacterial labyrinthitis or bacterial meningitis
  • Cochlear ossification shown on preoperative imaging

  • Pre-implantation cochlear assessment unfavorable to the implantation surgery
  • Absence of residual hearing shown by preoperative audiometry
  • History of bacterial labyrinthitis or bacterial meningitis
  • Cochlear ossification shown on preoperative imaging
  • Homozygous pathogenic mutations identified by molecular diagnosis of the SCL26A5 (prestin), TECTB (Beta-Tectorin) genes, and heterozygous of the COCH gene (Cochlin) prior to implantation (if available)
  • Vulnerable subject: minors, protected adults as defined by the Public Health Code, pregnant or breastfeeding women, subject under guardianship or subject deprived of liberty
  • Participation in another pharmacological therapeutic treatment clinical research Exclusion Criteria for the Control group:
  • Contraindication to surgery detected during the preoperative assessment
  • Fluctuating hearing = fluctuating hearing thresholds on at least one ear (shown by past bone conduction pure-tone audiometries)
  • History of bacterial labyrinthitis or bacterial meningitis

  • Chronical immune or inflammatory disease
  • Active viral or bacterial infection on the day of inclusion visit or surgery
  • Fever on the day of the first blood sample
  • Vulnerable subject: minors, protected adults as defined by the Public Health Code, pregnant or breastfeeding women, subject under guardianship or subject deprived of liberty
  • Participation in another pharmacological therapeutic treatment clinical research
