Official title A Study of DB-OTO, an Adeno-Associated Virus (AAV) Based Gene Therapy, in Children/Infants, Adolescents and Adults With Hearing Loss Due to Otoferlin Mutations
ClinicalTrials.gov ID: NCT05788536
What this study is testing
What is DB-OTO?
DB-OTO is an investigational medicine, being studied as a potential treatment for congenital hearing loss secondary to biallelic mutations of the otoferlin gene (otof).
Also referred to as Otarmeni™, Otoferlin.
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
- Regeneron is conducting a study of an investigational new drug called DB-OTO. DB-OTO is a gene therapy that is being developed to treat pediatric and adult participants who have severe-to profound and profound hearing loss due to changes in the otoferlin gene.
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.

- No clinically significant laboratory findings on clinical laboratory tests at time of Screening as described in the protocol
- Audiological Criteria:
- Investigator diagnoses the participant with profound sensorineural hearing loss (SNHL; \>90 dB HL) based on behavioral and physiologic measurements (ABR) of inner ear function
- Outer hair cell presence is confirmed via presence of otoacoustic emissions (≥6 dBSNR) at ≥3 frequencies from 1 to 8 kHz in the ear(s) to be infused with DB-OTO. Alternatively, for participants \>24 months of age, outer...
- No evidence from measures of hearing loss that show a dependence on body temperature
