SAN DIEGO, May 11, 2021 (GLOBE NEWSWIRE) -- Otonomy, Inc. (Nasdaq: OTIC), a biopharmaceutical company dedicated to the development of innovative therapeutics for neurotology, today reported financial results for the quarter ended March 31, 2021 and provided an update on its product pipeline and corporate activities. The company will host a conference call and webcast today at 4:30 p.m. ET to discuss recent highlights and financial results.

“We are focused on advancing our multiple programs for treating hearing loss and tinnitus as demonstrated by the recent initiation of our Phase 2 trial for OTO-313, ongoing preparation for initiating the expansion of the Phase 1/2 trial for OTO-413 this quarter, and upcoming presentation of preclinical proof-of-concept results for our OTO-825 gene therapy program,” said David A. Weber, Ph.D., president and CEO of Otonomy. “Our strengthened balance sheet will fund the Company well beyond our anticipated clinical milestones in mid-2022 and supports the advancement of our multiple preclinical programs including the IND-enabling activities for OTO-825.”

Otonomy Program Updates

• OTO-313: Phase 2 trial in tinnitus initiated with top-line results expected in mid-2022. Otonomy recently initiated a Phase 2 trial of OTO-313, based on the design of the successful Phase 1/2 trial, that will enroll approximately 140 patients with persistent, unilateral tinnitus of at least moderate severity. To enrich the study population, this trial is excluding patients with severe hearing loss and has an increased minimum Tinnitus Functional Index (TFI) score required for entry. Otonomy is expanding the unilateral patient population eligible for enrollment by increasing the maximum time from tinnitus onset from six months up to one year. The primary endpoint is the same as reported for the Phase 1/2 trial: a responder analysis based on the proportion of patients who report a clinically meaningful improvement in TFI from baseline at both Month 1 and Month 2 following treatment. The follow-up period has also been extended out to four months to assess durability of the observed treatment effect. 
  
  
• OTO-413: Phase 1/2 trial expansion in hearing loss planned to start in second quarter of 2021 with top-line results expected in mid-2022. In December 2020, Otonomy announced positive top-line results from an ascending single dose safety and exploratory efficacy study for OTO-413 in patients with hearing loss. This trial demonstrated that a single intratympanic injection of OTO-413 was well-tolerated across all dose cohorts. Furthermore, the therapeutic activity of OTO-413 versus placebo was demonstrated across multiple clinically-validated speech-in-noise hearing tests at consecutive time points (Days 57 and 85). Beginning in the second quarter of 2021, Otonomy plans to enroll approximately 30 hearing loss patients in an expansion of the Phase 1/2 trial to evaluate a refined study protocol in preparation for Phase 2. This expansion trial will randomize subjects to a single treatment with OTO-413 or placebo and evaluate a reduced number of endpoints focusing on the phrase, word and digit speech-in-noise hearing tests assessed in the initial patient cohorts. Enrollment criteria will continue to target a broad hearing loss population to support design of a Phase 2 trial.
  
  
• OTO-825: IND-enabling activities underway for GJB2 gene therapy for congenital hearing loss with preclinical proof-of-concept data to be presented at ASGCT. OTO-825 is an AAV-based gene therapy to restore hearing in patients with hearing loss caused by a mutation in the gap junction beta-2 (GJB2) gene -- the most common cause of congenital hearing loss. Previously presented preclinical data demonstrate that a gene of interest can be expressed in support cells of the cochlea, which are the relevant target cells for treating GJB2 deficiency, and that consistent gene expression can be observed for at least 12 weeks in non-human primates following a single local administration. Otonomy recently announced that preclinical results demonstrating the successful recovery of hearing and cochlear morphology in two preclinical models of GJB2 deficiency will be presented on May 13, 2021 at the American Society of Gene & Cell Therapy (ASGCT) Annual Meeting. These results supported the selection of OTO-825 for advancement into IND-enabling activities, which are ongoing. An update on this program will be provided in mid-2021.
  
  
• OTO-510: preclinical development ongoing for novel and proprietary otoprotection molecule. Cisplatin is a potent chemotherapeutic agent that is widely used to treat a variety of cancers in adults and children, however, it is commonly associated with severe adverse effects including cisplatin-induced hearing loss (CIHL). Otonomy has identified a novel series of molecules with improved otoprotection in preclinical CIHL studies compared to other agents in development. Preclinical development continues for a small molecule from this class formulated to provide sustained exposure from a single intratympanic injection. The goal of the OTO-510 program is to preserve hearing without protecting the tumor.
  
  
• OTO-6XX: preclinical development ongoing for hair cell repair and regeneration program. In July 2020, Otonomy entered into an exclusive license agreement with KYORIN Pharmaceutical Co., Ltd. (Kyorin) that provides Otonomy with exclusive worldwide rights to develop, manufacture and commercialize a novel compound for the treatment of sensorineural hearing loss. Otonomy is formulating the patent-protected compound utilizing the company’s proprietary technology to provide sustained drug exposure in the inner ear following a single local administration. The OTO-6XX program targets hair cell repair and regeneration for the treatment of severe hearing loss.
  
  
• OTIVIDEX^®: following completion of analysis, no further support of the program is planned. In February 2021, Otonomy announced the results of a third Phase 3 trial for OTIVIDEX in Ménière’s disease. This trial failed to achieve its primary endpoint, which is based on the intent-to-treat population (p value = 0.312). The trial did achieve statistical significance for the per protocol population (p value = 0.031). Based on a comprehensive analysis of the results, Otonomy has decided not to pursue additional development of the product candidate.
  
  
• OTIPRIO^®: evaluating strategic alternatives. In June 2020, Otonomy entered a co-promotion agreement that provided ALK-Abelló, Inc. (ALK) with an exclusive right to promote OTIPRIO for acute otitis externa (AOE). This agreement was expanded in October 2020 to include OTIPRIO’s other FDA-approved indication, use during ear tube surgery. Following the negative Phase 3 results for OTIVIDEX, Otonomy notified ALK of its intent to evaluate strategic alternatives for the product, which is ongoing.
  

Anticipated Upcoming Milestones

• In the second quarter of 2021, initiate an expansion of the Phase 1/2 clinical trial of OTO-413.
  
  
• In mid-2021, provide update on OTO-825 gene therapy program.
  
  
• In mid-2022, announce top-line results for OTO-313 Phase 2 clinical trial.
  
  
• In mid-2022, announce top-line results for OTO-413 Phase 1/2 expansion trial.
