This study evaluates AAVAnc80-hOTOF, a gene therapy delivered with a dedicated delivery device, in people with hearing loss caused by changes in the otoferlin (OTOF) gene. Participants with at least two mutations in the otoferlin gene and profound hearing loss in both ears may take part. The study is in Phase 1/Phase 2 and is currently enrolling participants.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
Criteria for Inclusion: 1. Participants may be of any age, based on Cohort Criteria 2. At least two mutations in the otoferlin gene 3. Clinical presentation of Profound (Part A) or Severe to Profound (Parts B, C, and D) bilateral sensorineural hearing loss as assessed by ABR 4. Preserved distortion product otoacoustic emissions (DPOAEs) 5. Able and willing to comply with all study requirements, including willingness to participate in a separate long term follow-up study after completion of this trial Criteria for Exclusion: 1. Persistent ear infections, anatomic or other abnormalities of the ear, and/or medical conditions that would contraindicate undergoing surgery, anesthesia, and/or administration of investigational gene therapy 2. Cochlear Implant(s) in the ear(s) to receive AAVAnc80-hOTOF 3. Prior participation in a clinical trial with an investigational drug, within six months prior to administration, or any prior participation in a gene therapy clinical trial (with the exception of AK-OTOF-101 for Part D participants)
