2 Clinical Trials for Various Conditions
This is an observational study to examine the characteristics of gene-related hearing loss in pediatric participants with biallelic otoferlin (OTOF) Mutations, Gap Junction Beta 2 (GJB2) Mutations, or Digenic GJB2/Gap Junction Beta 6 (GJB6) Mutations. This study will follow the participant for 4 years with annual visits each year.
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 children who have hearing loss due to changes in the otoferlin gene. The purpose of this study is to: * Learn about the safety of DB-OTO * Determine how well DB-OTO is tolerated (does not cause ongoing discomfort) * Evaluate the efficacy of DB-OTO (how well DB-OTO works)
