U.S. FDA approves first-ever gene therapy for inherited deafness, free to patients
The FDA has approved the first-ever gene therapy for inherited deafness. In its 20-child trial, 16 saw their hearing improve within months — and some could make out whispers for the first time.
Called Otarmeni, the one-time treatment uses two harmless viruses to deliver working copies of the OTOF gene deep into the inner ear, restoring otoferlin, the protein the cochlea needs to turn sound into signals the brain can read. Its maker, Regeneron, says it will offer the therapy free to patients in the U.S. Doctors who ran the trial described children responding to their parents’ voices, and to music, for the first time.
This particular genetic form of deafness is rare, affecting roughly 50 babies born in the U.S. each year. But researchers believe the breakthrough cracks open the door to gene therapies for many other inherited conditions worldwide.
