Treatment of Congenital Hearing Loss Secondary to Biallelic Mutations of the Otoferlin Gene study: EHT102 Injection
Official title A Clinical Trial of EHT102 Injection in Pediatric Patients With Biallelic hOTOF Mutations
ClinicalTrials.gov ID: NCT07288580
What this study is testing
What is EHT102 Injection?
This is an investigational gene therapy being studied as a potential treatment for congenital hearing loss caused by specific gene changes. It is designed to deliver a copy of a healthy gene into the inner ear cells to help restore hearing function.
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
- The study wants to see if the injection is safe, well tolerated, and may help hearing in these kids.
- Who it's for
- Pediatric patients who have two copies of a harmful OTOF gene mutation that causes hearing loss.
- What's involved
- Participants will receive a single injection into one ear and then be monitored for safety. The dose may be increased in small groups.
- Time commitment
- Up to 30 children may join, with 3 in each of two dose groups, and they will have follow‑up visits to check safety and hearing.
- 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.
