Research summary
OTOF-mediated hearing loss is caused by mutations in the otoferlin gene which prevents normal functioning of the ear and results in hearing loss.
Currently there are no medicinal treatment options available for OTOF-mediated hearing loss.
This study will investigate a method of gene therapy, where the study drug will be used to transfer a normal copy of the otoferlin gene into the ear by a single surgical procedure. An adeno-associated virus (AAV) which does not cause illness, will be used to carry the normal gene into the ear.
This study is split into Part A and Part B. During Part A participants will receive the study drug at one of two doses. The dose they receive will depend upon what point the study is at when the participant enrolls. The results of Part A will determine what dose level is used for Part B.
The aim of this study is to evaluate if the study drug is safe and if it improves hearing in individuals with OTOF-mediated hearing loss.
Approximately 14 participants ages 2 to 17 years old will take part in Part A of this study.
Each participant will be in the study for approximately 27 months. This includes a screening period of up to 3 months and a 24-month (2 year) observation period following administration of the study drug. Participants will be expected to participate in a separate long term follow-up protocol for up to five years after administration of the study drug.
