SAN DIEGO, Sept. 9, 2015 (GLOBE NEWSWIRE) -- Otonomy, Inc. (Nasdaq:OTIC), a clinical-stage biopharmaceutical company focused on the development and commercialization of innovative therapeutics for diseases and disorders of the ear, today announced that it has successfully completed an End-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) for OTO-104 in the treatment of Ménière's disease. As a result, the company reiterates its prior guidance given in the second quarter earnings release that it expects to initiate two parallel Phase 3 trials for OTO-104 in Ménière's patients, with the first trial expected to begin by the end of 2015 and the second trial expected to begin during the first quarter of 2016.

About OTO-104

OTO-104, which has been granted Fast Track designation by the U.S. Food and Drug Administration (FDA), is a sustained-exposure formulation of the steroid dexamethasone in development for the treatment of Ménière's disease and other inner ear conditions. Otonomy has recently completed a randomized, prospective, double-blind, placebo-controlled single-dose Phase 2b trial in a total of 154 Ménière's disease patients. Top-line results indicate that OTO-104 narrowly missed the primary efficacy endpoint (p=0.067) but achieved statistical significance (p<0.05) for multiple prospectively defined secondary vertigo endpoints at multiple time points. Based on these results Otonomy intends to initiate two parallel Phase 3 trials, with one of the trials expected to begin by the end of 2015 and the second trial expected to begin during the first quarter of 2016. OTO-104 is also being evaluated in a multiple-dose safety study in the United Kingdom in patients with Ménière's disease, and enrollment has been completed with a total of 128 patients.

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.
