SAN DIEGO, Aug. 01, 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 successful completion of a one-year, multiple-dose clinical safety trial of OTO-104 in patients with Ménière’s disease. This prospective, randomized, placebo-controlled clinical safety trial enrolled a total of 128 patients across multiple trial sites in the United Kingdom and demonstrated that quarterly dosing of OTO-104 was well tolerated.
In the first part of this trial, patients were randomized to receive two doses of either placebo or OTO-104 by intratympanic (IT) injection given at a three-month, or "quarterly", interval. Patients completing the double-blind portion of the study were eligible to receive two IT injections of OTO-104 given at a quarterly interval. A total of 90 patients received four quarterly doses of OTO-104 reflecting a greater than 90% compliance rate during the double-blind and open label portions of the trial. There were no notable differences in treatment emergent adverse events, audiometry or tympanometry between patients in the OTO-104 and placebo groups. In general, the safety profile observed with quarterly dosing of OTO-104 was comparable to that observed from previous clinical trials with a single dose of OTO-104.
“On behalf of my fellow investigators, I would like to thank the Ménière’s patients who participated in this year-long trial,” said John Phillips, Consultant ENT Surgeon at the Norfolk and Norwich University Hospital, and Coordinating Investigator of the trial. “The high patient compliance rate, review of adverse event reports and all safety data by the Drug Safety Monitoring Board throughout the trial, and post-study assessment of otoscopy, audiometry and tympanometry data supports that quarterly dosing with OTO-104 is generally well tolerated by patients.”
“Since Ménière’s disease is a chronic disorder, the demonstration that repeat-dosing with OTO-104 is well tolerated by patients is an important component of our registration program,” said David A. Weber, Ph.D., president and CEO of Otonomy. “Furthermore, this clinical trial also provided helpful experience with the use of OTO-104 by investigators who are now recruiting patients in the ongoing single-dose AVERTS-2 Phase 3 efficacy trial.”
About Ménière's Disease
Ménière’s disease is a chronic condition characterized by acute vertigo attacks, tinnitus, fluctuating hearing loss and a feeling of aural fullness. Of these symptoms, the vertigo attacks are typically most troubling for patients since they disrupt daily activities and are difficult to anticipate and manage. In general, patients are diagnosed with unilateral Ménière’s disease in middle age and symptoms often continue for decades. Over time, the fluctuating hearing loss becomes permanent in many patients, and a subset of patients will develop symptoms in their second ear. According to the National Institute of Deafness and Other Communication Disorders, there are more than 600,000 patients diagnosed with Ménière’s disease in the United States. There is no known cure for Ménière’s disease and there are currently no FDA-approved drug treatments.
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 two Phase 3 trials, AVERTS-1 in the United States and AVERTS-2 in the European Union. 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.
Otonomy is a biopharmaceutical company focused on the development and commercialization of innovative therapeutics for diseases and disorders of the ear. OTIPRIO (ciprofloxacin otic suspension) is approved in the United States for use during tympanostomy tube placement surgery in pediatric patients, and commercial launch commenced in March 2016. OTO-104 is a steroid in development for the treatment of Ménière's disease and other severe balance and hearing disorders. Two Phase 3 trials in Ménière's disease patients are underway, with results expected during the second half of 2017. OTO-311 is an NMDA receptor antagonist for the treatment of tinnitus that is in a Phase 1 clinical safety trial. Otonomy’s proprietary formulation technology utilizes a thermosensitive gel and drug microparticles to enable single dose treatment by a physician.
