Decibel Therapeutics, Inc., a clinical-stage biotechnology company, engages in discovering and developing transformative treatments for hearing and balance disorders. Its product candidates and programs focuses on three areas, such as Gene Therapies for Congenital, Monogenic Hearing Loss designed to restore functional cells within the cochlea to address hearing disorders caused by single gene mutations; Gene Therapies for Hair Cell Regeneration designed to replace lost hair cells within the inner ear to address acquired hearing loss and balance disorders; and Otoprotection Therapeutic in clinical development to prevent hearing loss in cancer patients undergoing chemotherapy with cisplatin. The company's lead gene therapy product candidate is DB-OTO to provide hearing to individuals born with profound hearing loss due to mutation of the otoferlin gene. It is also developing DB-ATO, a gene therapy program designed to restore balance in patients with bilateral vestibulopathy by regenerating lost hair cells within the inner ear; and DB-020 for the prevention of cisplatin-induced hearing loss, which is in Phase 1b clinical trial. Decibel Therapeutics, Inc. has a strategic collaboration with Regeneron Pharmaceuticals, Inc. to develop gene therapies for monogenic forms of congenital hearing loss. The company was formerly known as Hearing Inc. and changed its name to Decibel Therapeutics, Inc. in April 2014. Decibel Therapeutics, Inc. was incorporated in 2013 and is headquartered in Boston, Massachusetts.
