Akouos Receives Orphan Drug and Rare Pediatric Disease Designations for AK-OTOF for the Treatment of Otoferlin Gene-Mediated Hearing Loss Nasdaq:AKUS

BOSTON, April 13, 2021 (GLOBE NEWSWIRE) – Akouos, Inc. (NASDAQ: AKUS), an accurate genetic medicine company dedicated to developing potential gene therapies for people with hearing loss worldwide, announced today that the U.S. Food and Drug Administration (FDA) has adopted both Orphan Drug Designation (ODD) and Rare Pediatric Disease Designation (RPDD) awarded for AK-OTOF, a gene therapy intended for the treatment of Otoferlin gene-mediated hearing loss. Akouos expects to submit a research application for new drugs (IND) for AK-OTOF in the first half of 2022.

Otoferlin gene (OTOF) mediated hearing loss is a form of sensorineural hearing loss caused by mutations in the OTOF gene. The OTOF gene codes for otoferlin, a protein that enables the inner hair cells of the cochlea to release neurotransmitter vesicles in response to sound stimulation to activate auditory neurons. Most people with OTOF-mediated hearing loss have severe to profound sensorineural hearing loss from birth, and approximately 20,000 people are affected in the United States and Europe. AK-OTOF is designed to treat the underlying cause of OTOF-mediated hearing loss by delivering a transgene using a dual vector technology that results in expression of normal, functional otoferlin protein in the affected cells, namely the inner hair cells, in the cochlea.

“There are currently no pharmacological treatment options for individuals with OTOF-mediated hearing loss, or for any other form of sensorineural hearing loss. The non-clinical data reported for AK-OTOF to date demonstrate sustainable recovery of auditory function and support future clinical development. “said Jen Wellman, Akouos chief operating officer.” We believe these are the first orphan drug and rare pediatric disease designations awarded by the FDA for a genetic form of hearing loss, and that this is an important milestone in the field of genetic medicines for the inner ear. Receiving both designations could help us accelerate the development of AK-OTOF, a therapy that we believe has the potential to restore physiological hearing and provide long-term benefits to these individuals and their families . “

The FDA’s Office of Orphan Products Development grants ODD to drugs and biologics intended for the treatment, diagnosis, or prevention of rare diseases or conditions that affect fewer than 200,000 people in the United States. The designation offers Akouos the potential for certain benefits, including up to seven years of post-approval market exclusivity, drug development assistance, clinical development tax credits and exemptions from certain FDA fees.

The FDA grants the rare pediatric disease designation to encourage the development of treatments for serious or life-threatening rare diseases, where the symptoms primarily affect individuals from birth to 18 years of age. Under the Priority Review Voucher Program, and subject to FDA approval of AK-OTOF for the treatment of OTOF-mediated hearing loss, Akouos may qualify for one Priority Review voucher, which can then be redeemed for priority review for a subsequent marketing application for another product or sold or transferred to another sponsor.
