Gene Therapy for Hearing Loss
A Breakthrough Treatment for Genetic Hearing Loss
Otarmeni鈩 (lunsotogene parvec-cwha) is the first FDA-approved gene therapy for children with genetic hearing loss, offering the potential of hearing restoration without the need for a device like a hearing aid or cochlear implant.
Children whose deafness is caused by mutations in their OTOF gene 鈥 an inner ear gene that helps the body produce otoferlin, one of the many important proteins for hearing 鈥 may be eligible for Otarmeni, a procedure that restores natural otoferlin production.
As a leader in research and participant in numerous clinical trials, 91大神 Children鈥檚 is among the first in the nation to begin offering this life-changing treatment.
Leading the Way From Research to Reality
91大神 was actively involved in the successful clinical trials that helped Otarmeni gene therapy earn FDA approval.
In these trials, 80% of participants saw an improvement in their hearing level at an assessment conducted after 24 weeks.
A group of these successful participants were followed for an additional 24 weeks, and over that extended time, 42% were able to achieve normal hearing that included whispers.
Our experts will work together throughout your child's journey to help them experience the gift of sound.
How It Works
The OTOF gene, located in the inner ear, helps a child鈥檚 body produce a protein called otoferlin. This protein is essential for the hearing signal to travel from the ear to the brain, where it is interpreted as sound. Mutations to this gene can create an otoferlin deficiency, ultimately resulting in deafness.
With Otarmeni gene therapy, a functional copy of the OTOF gene, transported by a modified (noninfectious) virus, is infused into the cochlea, the part of the inner ear that converts sound waves into hearing signals. The virus then delivers the gene to inner hair cells and provides instructions for otoferlin production, correcting the deficiency. By restoring the transmission of signals between the inner ear and the brain, hearing is allowed to occur naturally.
This intracochlear infusion is surgically delivered, using a similar approach to that of a cochlear implant operation, and is performed under general anesthesia. Your child will most likely stay overnight in the hospital for observation.
After the procedure, regular follow-up visits with our multidisciplinary care team will allow us to test your child's hearing, track their speech and language progress, and ensure the best possible results.

鈥We'd been told that the only way she might hear would be with hearing aids or cochlear implants. Dr. Pritchett communicated with us so well about this procedure and how it works that I said, 'Let鈥檚 go for it.' I want my baby to hear.鈥
