Conference call and webcast today at 4:30 p.m. EDT

SAN DIEGO, Aug. 01, 2019 (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 June 30, 2019 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. EDT to discuss recent highlights and financial results.

"We are on track in executing our business plan and focused on reporting clinical results from three trials in 2020 -- the Phase 3 trial of OTIVIDEX in Ménière’s disease, the Phase 1/2 clinical trial of OTO-313 in tinnitus and the Phase 1/2 trial of OTO-413 in hearing loss," said David A. Weber, Ph.D., president and CEO of Otonomy. “We are also tracking to our financial plan and guidance that will enable our existing capital to fund operations through these three clinical trial results next year and into 2021."

Product Pipeline Update

OTIVIDEX™: Enrollment in Phase 3 Clinical Trial in Ménière’s Disease is Ongoing with Results Expected in the First Half of 2020. Otonomy has completed one successful Phase 3 trial and is conducting this additional pivotal trial to support a submission for U.S. registration of OTIVIDEX in Ménière’s disease. The company plans to enroll approximately 160 patients in the United States and Europe.

OTO-313: Enrollment in Phase 1/2 Clinical Trial in Tinnitus is Ongoing with Results Expected in the First Half of 2020. In April, Otonomy initiated enrollment of the first patients in a Phase 1/2 clinical trial for OTO-313, a sustained-exposure formulation of the NMDA receptor antagonist gacyclidine, in tinnitus patients. The randomized, double-blind, placebo-controlled trial included an initial safety cohort, which has been successfully completed, followed by an exploratory efficacy study that is currently enrolling approximately 50 patients with tinnitus.

OTO-413: Preparing to Initiate a Phase 1/2 Clinical Trial in Hearing Loss Patients in the Third Quarter of 2019. OTO-413 is a sustained-exposure formulation of brain-derived neurotrophic factor (BDNF) in development for the repair of cochlear synaptopathy, an underlying cause of hearing loss. Otonomy is preparing to initiate a Phase 1/2 clinical trial in the third quarter of 2019 that will enroll approximately 40 patients with speech-in-noise hearing loss.

"Additionally, I would like to take this opportunity to express my best wishes to Dr. Kathie Bishop, chief scientific officer, who has resigned in order to join a former colleague in an early-stage venture," said Dr. Weber. "We appreciate the support that Kathie provided during the last two years as we positioned the company for our upcoming clinical milestones and look forward to her continued involvement as a scientific advisor."

Anticipated Upcoming Milestones

In third quarter of 2019, initiate a Phase 1/2 clinical trial of OTO-413 in hearing loss patients.

In first half of 2020, complete OTO-313 Phase 1/2 clinical trial.

In first half of 2020, complete Phase 3 trial for OTIVIDEX in Ménière’s disease.

In second half of 2020, complete OTO-413 Phase 1/2 clinical trial.

Second Quarter Financial Highlights

Cash Position: Cash, cash equivalents, and short-term investments totaled $78.5 million as of June 30, 2019, compared to $97.3 million as of December 31, 2018.

Operating Expenses: GAAP operating expenses were $11.8 million for the second quarter of 2019, compared to $13.8 million for the second quarter of 2018. Non-GAAP operating expenses, which exclude stock-based compensation, were $10.6 million for the second quarter of 2019, compared to $9.4 million for the second quarter of 2018.

Research and Development Expenses: GAAP research and development (R&D) expenses for the second quarter of 2019 were $8.9 million, compared to $8.2 million for the second quarter of 2018. A slight net increase in expenses for this quarter compared to a year ago resulted from an increase in expenses for the OTIVIDEX and OTO-313 clinical trials and OTO-413 nonclinical and manufacturing activities that were partially offset by a decrease in stock-based compensation.

Selling, General and Administrative Expenses: GAAP selling, general and administrative (SG&A) expenses in the second quarter of 2019 were $2.9 million, compared to $5.6 million for the second quarter of 2018. The decrease this quarter was primarily a result of reduced stock-based compensation expense together with OTIPRIO cost reimbursement received from our OTIPRIO co-promotion partners.

Financial Guidance: 2019 Operating Expenses: Otonomy expects that GAAP operating expenses will be in the range of $55-$60 million, and that non-GAAP operating expenses will be in the range of $45-$50 million. 2020 Operating Expenses: Otonomy expects that operating expenses will be lower than 2019 as multiple clinical trials are completed. Cash Runway: Otonomy expects that its current cash, cash equivalents, and short term investments will be sufficient to fund the company through completion of the OTIVIDEX Phase 3 trial, OTO-313 Phase 1/2 trial, and OTO-413 Phase 1/2 trial in 2020, and will support company operations into 2021.
