To restore hearing function in patients with hearing loss or deafness, cochlear implantation is seen as the only method that works, but insertion of the electrode array may cause direct mechanical injury to the cochlea, with the subsequent loss attributed to an inflammatory response driven by proinflammatory cytokines, reactive oxygen species and apoptotic signals.
The TMEM43 gene encodes a transmembrane protein that is associated with connexin-linked function in cochlear glia-like supporting cells (GLSs), and mutations in this gene have been recently associated with hearing loss (HL).

Decibel Therapeutics Inc. has received clearance of its clinical trial application (CTA) by the U.K.'s Medicines and Healthcare products Regulatory Agency (MHRA) to initiate a phase I/II trial of gene therapy DB-OTO in pediatric patients with congenital hearing loss due to an otoferlin deficiency.
The FDA has awarded orphan drug designation to Sensorion SA's OTOF-GT, a dual vector AAV gene therapy, for the treatment of otoferlin gene-mediated hearing loss.
Acousia Therapeutics GmbH, and its partners at the Tübingen Hearing Research Center at University of Tübingen, have generated new preclinical data in support of hearing loss drug candidates ACOU-085 and ACOU-082.
The volatile gene therapy space is getting a boost with Eli Lilly and Co.’s acquisition of Akouos Inc., which only a month before had received the first IND from the U.S. FDA for an adeno-associated virus (AAV)-based hearing loss treatment. Lilly plans to pay about $610 million for the company to get at AK-OTOF, Akouos’ lead candidate for treating hearing loss due to mutations in the otoferlin gene.
Decibel Therapeutics Inc. has received clearance from the FDA for its IND application to initiate a phase I/II trial of DB-OTO in pediatric patients, potentially in infants younger than 2 years of age.
Akouos Inc. has received IND clearance from the FDA to initiate a first-in-human phase I/II pediatric trial of AK-OTOF, a gene therapy intended for the treatment of patients with otoferlin gene (OTOF)-mediated hearing loss.
