Multiple clinical trial readouts for OTO-313 in tinnitus and OTO-413 in hearing loss expected during 2022
Current capital funds operations into second half of 2023
SAN DIEGO, Jan. 06, 2022 (GLOBE NEWSWIRE) -- Otonomy, Inc. (Nasdaq: OTIC), a biopharmaceutical company dedicated to the development of innovative therapeutics for neurotology, today provided an update on its product pipeline and financial guidance. Consistent with previously stated timing, the company expects to report results for the Phase 2a cohort of OTO-413 in hearing loss patients early in the second quarter of 2022 and the Phase 2 trial of OTO-313 in tinnitus patients in mid-2022. The company also plans to initiate a clinical safety evaluation of higher unilateral as well as bilateral dosing of OTO-313 and, as previously announced, has initiated clinical evaluation of higher dosing of OTO-413. Results of these multiple studies are expected to inform initiation of a full dose-ranging Phase 2 trial for OTO-413 by the end of 2022 and start of the Phase 3 clinical program for OTO-313 in the first half of 2023.
The company finished 2021 with approximately $77 million in cash, cash equivalents and short term investments and expects that its current capital is sufficient to fund operations into the second half of 2023.
“We are excited to begin 2022, a catalyst-rich year for Otonomy because of our multiple clinical trial readouts for both OTO-313 and OTO-413, novel products that target large patient populations with high disease burden and no approved drug treatment,” said David A. Weber, Ph.D., president and CEO of Otonomy. “For OTO-313, we expect to generate robust clinical data to inform the Phase 3 program by having efficacy readouts for Months 1 and 2 as well as the extended follow-up period out to Month 4, and we will also have safety data for both a higher unilateral OTO-313 dose and bilateral dosing. Similarly, efficacy data from the OTO-413 Phase 2a cohort plus ongoing dose escalation evaluation will provide a good basis for initiating a full dose-ranging Phase 2 efficacy trial for OTO-413 later this year.”
Product Pipeline Update
OTO-313: Phase 2 trial in tinnitus is ongoing with top-line results expected in mid-2022; initiating safety evaluation of higher and bilateral dosing. Otonomy is conducting a Phase 2 trial of OTO-313 that will enroll approximately 140 patients with persistent, unilateral tinnitus of at least moderate severity. Patients are being randomized 1:1 to a single intratympanic injection of OTO-313 (0.32 mg) or placebo. 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. Following the positive Phase 1/2 trial, Otonomy conducted additional nonclinical testing and successfully completed a Type C meeting with the U.S. Food and Drug Administration (FDA) in December supporting initiation of a 1-month safety study for bilateral and higher (0.64 mg) dosing of OTO-313. Additional efficacy results from the Phase 2 extended observation period and safety data from the bilateral and higher unilateral dose study are anticipated in the second half of 2022. Altogether, these multiple clinical data readouts for OTO-313 are expected to support an End-of-Phase 2 meeting with the FDA and inform the design of the Phase 3 clinical program planned to start in the first half of 2023.OTO-413: Phase 2a cohort in hearing loss is fully enrolled with top-line results expected early in the second quarter of 2022; clinical evaluation of higher dosing initiated. Otonomy has completed enrollment in the Phase 2a cohort for the highest OTO-413 dose (0.3 mg) evaluated in the initial Phase 1/2 trial cohorts. A total of 33 patients with hearing loss were randomized 2:1 to receive a single intratympanic injection of OTO-413 or placebo. Patients are being followed for three months and assessed using multiple clinically-validated speech-in-noise hearing tests. Otonomy has also initiated enrollment to evaluate safety of at least one higher dose of OTO-413 (starting with 0.75 mg). Each dose cohort will enroll approximately 12 hearing loss patients randomized 2:1 to OTO-413 or placebo and patients will be assessed as in the Phase 2a. Based on results from the Phase 2a cohort and higher-dose safety evaluation, Otonomy expects to initiate a full dose-ranging Phase 2 efficacy trial by the end of 2022.OTO-825: preclinical studies validate 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 for OTO-825 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 to repair or regenerate cochlear hair cells that are 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
Early second quarter 2022, announce top-line results for OTO-413 Phase 2a cohort. In mid-2022, announce top-line results for OTO-313 Phase 2 clinical trial. In second half of 2022, announce top-line results for OTO-313 Phase 2 extended observation period and safety results for 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.
