Otonomy Announces Publication Supporting Development of OTO-104 as Protectant Against Cisplatin-Induced Hearing Loss

SAN DIEGO, Jan. 26, 2016 (GLOBE NEWSWIRE) -- Otonomy, Inc. (NASDAQ:OTIC), a biopharmaceutical company focused on the development and commercialization of innovative therapeutics for diseases and disorders of the ear, today announced the publication in Audiology & Neurotology of a preclinical study titled, “The Sustained-Exposure Dexamethasone Formulation OTO-104 Offers Effective Protection against Cisplatin-Induced Hearing Loss”. This study demonstrated that intratympanic administration of 6% OTO-104 protected against ototoxicity observed following both acute and repeat administration of the chemotherapeutic agent cisplatin.

“Our recent financing enables us to expand the scope of our development efforts, and the clinical evaluation of OTO-104 for the prevention of cisplatin-induced hearing loss is a priority based on the high unmet medical need, attractive market potential, and preclinical proof-of-concept presented in this publication,” said David A. Weber, Ph.D., president and CEO of Otonomy. “We have completed a pre-IND review by the FDA and expect to initiate a Phase 2 feasibility trial at multiple leading oncology centers in the second half of 2016.”

“Hearing loss caused by cancer treatment with platinum-based chemotherapy agents is well documented, and the negative impact on the quality of life of cancer survivors, especially children and adolescents, is highly significant,” said Dr. David Freyer, Professor of Clinical Pediatrics and Medicine at the Keck School of Medicine, University of Southern California, and Director, Survivorship and Supportive Care Program of the Children’s Center for Cancer and Blood Diseases at Children’s Hospital of Los Angeles. “There is great interest among pediatric oncologists, hearing specialists, and parents in having a therapeutic agent that can protect against hearing loss without concern for interfering with the effectiveness of the chemotherapy. Otic delivery of OTO-104 has this potential based on the preclinical profile in this study.”

About Cisplatin-Induced Hearing Loss

Cisplatin and other platinum-based chemotherapeutic agents are routinely used in treating numerous tumor types with approximately 500,000 patients including 2,000 children treated each year in the United States. While use of platinum agents has contributed to improved patient survival, ototoxicity and associated permanent hearing loss is well documented in the clinical literature. In particular, hearing loss has been reported in up to 90% of children and young adults treated with platinum-based agents1. This adversely affects speech and language development and has been associated with academic and social difficulties. At this time, there is no FDA-approved drug treatment to protect against platinum-based ototoxicity.

About OTO-104

OTO-104 is a sustained-exposure formulation of the steroid dexamethasone in development for the treatment of various severe balance and hearing disorders. The first indication being pursued is Ménière's disease which is a chronic condition characterized by acute vertigo attacks, tinnitus, fluctuating hearing loss and a feeling of aural fullness. Based on supportive results from a Phase 2b trial, Otonomy has initiated a Phase 3 program. The first Phase 3 trial is underway in the United States and a second trial is expected to be initiated in the EU during the first quarter of 2016. Results of both Phase 3 trials are expected in the second half of 2017. OTO-104 has been granted Fast Track designation for this indication by the FDA. Otonomy also intends to initiate clinical development for OTO-104 in a second indication, the prevention of hearing loss associated with cisplatin chemotherapy. Otonomy expects to initiate a Phase 2 feasibility clinical trial for OTO-104 in this indication in the second half of 2016.
