BOSTON, MASSACHUSSETTS – Decibel Therapeutics, a clinical-stage biotechnology company dedicated to discovering and developing treatments to restore and improve hearing and balance, has announced a partnership with Invitae, a leading medical genetics company, to launch AmplifyTM, a no-charge genetic testing program to screen for the genetic cause of congenital hearing loss in children diagnosed with auditory neuropathy.
“We are pleased to collaborate with Invitae to introduce AmplifyTM, which is designed to bring patients one step closer to molecular diagnosis and clinical management of auditory neuropathy, a disorder that affects approximately 10 percent of children who are born with hearing loss. This program seeks to provide much-needed answers to patients and families of patients who experience congenital, monogenic hearing loss. We hope that AmplifyTM will provide those patients with a better understanding of their diagnosis and their treatment options.”
–Jonathon Whitton, Au.D., Ph.D., VP of Clinical Research at Decibel
Auditory neuropathy is a hearing disorder in which the cochlea, the hearing organ located in the inner ear, receives sound normally, yet the transmission of sound to the brain is interrupted.
The most common genetic cause of auditory neuropathy is insufficient production of a protein called otoferlin, which facilitates communication between the inner ear sensory cells and the auditory nerve. When this protein is lacking, the ear cannot communicate with the auditory nerve and the brain, resulting in profound hearing loss. Decibel’s lead investigational gene therapy program, DB-OTO, is designed to treat congenital, monogenic hearing loss caused by a deficiency in the otoferlin gene.
Amplify Program Eligibility
AmplifyTM is available to individuals who meet the following criteria:
- Absent or highly abnormal Auditory Brainstem Response (ABR) in both ears
- Presence of Distortion Product Otoacoustic Emissions (DPOAE) in at least three frequencies in at least one ear
- Less than five years of age
AmplifyTM is a no-charge program that offers genetic testing for those who qualify. Although genetic testing can confirm a potential diagnosis, the absence of a genetic alteration does not preclude a diagnosis of genetic hearing loss.

DB-OTO is Decibel’s investigational gene therapy to restore hearing in children with congenital hearing loss due to a deficiency in the otoferlin gene. The program, developed in collaboration with Regeneron Pharmaceuticals, uses a proprietary, cell-selective promoter to precisely control gene expression in cochlear hair cells. DB-OTO is in preclinical studies, and Decibel expects to initiate clinical testing in 2022.
Invitae Corporation (NYSE: NVTA) is a leading medical genetics company whose mission is to bring comprehensive genetic information into mainstream medicine to improve healthcare for billions of people. Invitae’s goal is to aggregate the world’s genetic tests into a single service with higher quality, faster turnaround time, and lower prices.
