SAN DIEGO, May 09, 2022 (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, 2022 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 excited about the positive OTO-413 Phase 2a trial results that we recently announced because they provide a second independent, placebo-controlled trial demonstrating the treatment benefit of OTO-413 in a broad hearing loss patient population,” said David A. Weber, Ph.D., president and CEO of Otonomy. “We look to build on this momentum with results from the OTO-313 Phase 2 tinnitus trial this summer followed by results from the evaluation of higher doses for OTO-413 in hearing loss patients and higher and bilateral dosing with OTO-313 in tinnitus patients later in the year.”

Otonomy Program Updates

• OTO-413: positive top-line results announced for Phase 2a cohort in hearing loss patients; clinical evaluation of higher dosing ongoing. In April 2022, Otonomy announced that a single intratympanic injection of 0.3 mg OTO-413 provided clinically meaningful treatment benefit versus placebo across multiple speech-in-noise (SIN) hearing tests as well as the Patient Global Impression of Change (PGIC) at consecutive time points (Days 57 and 85). The randomized, double-blind, placebo-controlled trial enrolled a total of 33 patients (30 evaluable) with self-reported hearing difficulty in a noisy environment that was confirmed by SIN testing. Overall, 40% (8 of 20) OTO-413 subjects demonstrated a clinically-meaningful improvement on at least one of the three SIN tests at both Days 57 and 85 versus 20% (2 out of 10) for placebo. For the Words-in-Noise test, which is well-established and validated in hearing loss patients, 40% (6 of 15 with evaluable tests) OTO-413 subjects demonstrated a clinically-meaningful improvement at both Days 57 and 85 versus 0% (0 of 9 with evaluable tests) for placebo. The PGIC also demonstrated a treatment benefit with 50% (10 of 20) OTO-413 subjects reporting an improvement from baseline at both Days 57 and 85 compared to only 10% (1 of 10) for placebo. Additionally, treatment with OTO-413 was well tolerated.

  Based on these positive results, Otonomy intends to initiate a full dose-ranging Phase 2 trial in hearing loss patients by the end of 2022. This trial will also incorporate learnings from the ongoing higher dose evaluations that are assessing the tolerability and treatment activity of two higher doses of OTO-413: 0.75 mg and 1.50 mg (five times the dose in the Phase 2a trial). Results from the higher dose evaluation are expected in the second half of 2022.

• OTO-313: Phase 2 trial in tinnitus is fully enrolled with top-line results expected in August 2022; safety evaluation of higher and bilateral dosing ongoing. Otonomy has completed the enrollment of 153 patients with persistent, unilateral tinnitus of at least moderate severity in a Phase 2 trial of OTO-313 (target enrollment was 140 patients). Patients were randomized 1:1 to a single intratympanic injection of OTO-313 (0.32 mg) or placebo and are being followed for four months. The primary endpoint is the same as reported for the successful Phase 1/2 trial: a responder analysis based on the proportion of patients who report a clinically meaningful improvement in the Tinnitus Functional Index (TFI) from baseline to Months 1 and 2 following treatment. To assess durability of the OTO-313 treatment effect, the follow-up period has been extended out to four months. Top-line results for all timepoints are expected to be available in August 2022. Additionally, Otonomy is conducting a one-month safety study for bilateral and higher (0.64 mg) dosing of OTO-313 with results expected in the second half of 2022. Together, these clinical data are expected to support an End-of-Phase 2 meeting with the FDA and inform the design of the OTO-313 Phase 3 clinical program planned to start in the first half of 2023.
• OTO-825: preclinical studies demonstrate therapeutic potential of GJB2 gene therapy for congenital hearing loss with Investigational New Drug (IND) filing expected in first half of 2023. OTO-825 is an AAV-based gene therapy to restore hearing in patients with a mutation in the gap junction beta-2 (GJB2) gene, the most common cause of congenital hearing loss. Preclinical proof-of-concept results, which have been presented at multiple scientific meetings, demonstrate that a single administration of OTO-825 rescues hearing loss and cochlear damage in two preclinical models representing a range of hearing loss severity caused by GJB2 deficiency. A Pre-IND meeting has been completed with the FDA, and IND-enabling activities are ongoing.
• 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. The goal of the OTO-510 program is otoprotection without tumor protection.
• OTO-6XX: preclinical development ongoing for severe hearing loss program. Otonomy is evaluating therapeutic approaches focused on the repair of cochlear hair cells damaged due to noise, aging or exposure to ototoxic chemicals. This mechanism is expected to be complementary to repair of cochlear synapses, which is addressed by OTO-413.

Anticipated Upcoming Milestones

• In August 2022, announce top-line results for OTO-313 Phase 2 clinical trial.
• In second half of 2022, announce safety results for OTO-313 bilateral and higher dosing.
• In second half of 2022, announce top-line results for OTO-413 higher dose evaluation.
• By end of 2022, initiate Phase 2 dose-ranging efficacy trial for OTO-413 in hearing loss.
• In first half of 2023, initiate Phase 3 clinical program for OTO-313 in tinnitus.
• In first half of 2023, file IND for OTO-825 in hearing loss associated with GJB2 gene mutation.
