Developed by the American biotechnology company Regeneron, this treatment named Otarmeni targets a rare type of deafness, affecting only about 50 newborns per year in the United States.
The U.S. health authorities announced on Thursday the authorization for the commercialization of a genetic therapy, the first of its kind, against a genetic form of deafness, a breakthrough that could pave the way for other treatments for these hearing deficits.
While two to three out of a thousand children are born with hearing impairment in the United States, with more than half of these early deafness cases being genetic, the development of targeted genetic therapies is giving great hopes.
Developed by the American biotechnology company Regeneron, this treatment named Otarmeni targets a rare type of deafness, affecting only about 50 newborns per year in the United States.
Treatment Offered for Free
It can now be offered to children and adults suffering from severe to profound deafness linked to certain mutations in the OTOF gene, responsible for a protein that transmits auditory signals from the inner ear to the brain.
While genetic therapies are generally extremely expensive, especially in the United States where they can cost several million dollars per patient, Regeneron surprised by announcing its intention to offer this treatment for free to eligible American patients.
Administered once as an injection into the ear by a surgeon, this innovative therapeutic solution has been hailed as revolutionary by parents of affected children. “It’s simply incredible,” said Sierra Smith, a young mother of a boy named Travis who benefited from the treatment. “He didn’t know his own name. He couldn’t hear me tell him how much I love him. And now, thanks to Regeneron and this incredible operation, he can listen to music, and he loves it, he loves to dance,” she recounted from the White House during an event celebrating an agreement between the Trump administration and the pharmaceutical company on the prices of other medications.
Improvement in 80% of Patients
A clinical trial conducted on 20 pediatric patients aged 10 months to 16 years showed a significant improvement in hearing in at least 80% of them after a few months.
The approval of this innovative treatment by the American Food and Drug Administration (FDA) “marks a new era in the treatment of genetic forms of hearing loss, where it is now possible to restore continuous natural hearing,” praised Dr. Eliot Shearer from Boston Children’s Hospital, who participated in the clinical trial, in a statement.
