Auris Medical Announces Enrollment of First Patient in HEALOS Study of AM-111 in Treatment of Idiopathic Sudden Sensorineural Hearing Loss

ZUG, Switzerland, Nov. 13, 2015 (GLOBE NEWSWIRE) -- Auris Medical Holding AG (NASDAQ:EARS), a clinical-stage company dedicated to developing therapeutics that address important unmet medical needs in otolaryngology, today announced enrolment of the first patient into the pivotal HEALOS clinical trial with AM-111. HEALOS will evaluate the efficacy, safety and tolerability of single dose intratympanic injections of AM-111 in the treatment of idiopathic sudden sensorineural hearing loss (ISSNHL; a.k.a. "sudden deafness"). The trial will enroll 255 patients suffering from acute severe to profound hearing loss within 72 hours from ISSNHL onset. They will be randomized to receive either AM-111 at 0.4 mg/mL or 0.8 mg/mL or placebo.

Auris Medical benefited for the design of the HEALOS trial from multiple discussions with European and US regulatory agencies. The primary efficacy endpoint for the trial is the improvement of pure tone hearing thresholds from baseline to Day 28 at the average of the three most affected contiguous test frequencies. HEALOS will be conducted in several European and Asian countries, involving more than 70 sites. It is the first of two pivotal trials in Auris Medical's phase 3 clinical development program with AM-111. The second trial, ASSENT, is expected to start enrolment in North America in the first half of 2016.

"We are very excited to begin enrolling patients in HEALOS", commented Bettina M. Stubinski, Auris Medical's Chief Medical Officer. "Sudden deafness can be a very frightening experience, especially when the hearing loss is severe or profound and accompanied by tinnitus, and chances for complete recovery are low. AM-111 has shown very promising results as an otoprotectant in acute hearing loss, and we expect HEALOS to be a major milestone on our way towards the development of the first specific therapeutic for this condition", she added. Results from HEALOS are expected for the second half of 2017.

About acute inner ear hearing loss

Acute inner ear hearing loss may be the consequence of various insults to the cochlea. It may result e.g. from overexposure to noise, bacterial or viral infections, inflammation, vascular compromise, or a variety of other factors. In acute inner ear hearing loss, sensorineural structures of the inner ear - inner and outer hair cells, neurons - are damaged, as well as other structures such as supporting cells or vascular tissues. The common observation is a temporary increase in hearing thresholds, i.e. hearing loss. Thanks to cellular defenses and intrinsic repair mechanisms, a certain amount of such hearing loss is frequently recovered in the subsequent days and weeks. The remaining hearing loss however is irreversible. Acute inner ear hearing loss may be accompanied by other disorders of the inner ear such as dizziness or tinnitus.

When acute hearing loss develops into permanent hearing loss, it may have chronically debilitating consequences. Hearing loss may have serious impacts on professional and personal lives, e.g. through avoidance or withdrawal from social situations, reduced alertness and increased risk to personal safety, impaired memory and ability to learn new tasks, or reduced job performance and earning power. To date, there exists no treatment for acute inner ear hearing loss with proven efficacy.

About AM-111

AM-111 contains the synthetic peptide D-JNKI-1 (D-stereoisomer of c-Jun N-terminal Kinase Inhibitor 1), an inhibitor of the JNK stress kinase coupled to an intracellular transporter. D-JNKI-1 is formulated in a biocompatible and fully biodegradable gel. It is administered by a single dose intratympanic injection into the middle ear. From there the drug diffuses through the round window membrane into the cochlea.

JNK is a signal transmitting enzyme that regulates a number of important cellular activities, including activation of genes encoding inflammatory molecules or promoting cell death (apoptosis). JNK is activated following various types of cochlear insults (stress) that may lead to acute inner ear hearing loss. AM-111 enters cells and binds to JNK, thereby inhibiting activation of transcription factors such as c-jun and c-fos. This in turn prevents JNK mediated apoptosis and inflammatory response, which could otherwise result in irreversible loss of hair cells and cochlear neurons. AM-111 supports natural recovery processes and helps to prevent or reduce chronic hearing loss.

AM-111's otoprotective effect has been demonstrated in various animal models of cochlear stress, including acute acoustic trauma, acute labyrinthitis (inflammation), drug ototoxicity (aminoglycosides), bacterial infection, cochlear ischemia and cochlear implantation trauma. Auris Medical will conduct two pivotal clinical trials (HEALOS and ASSENT) with AM-111 in the treatment of idiopathic sudden sensorineural hearing loss (ISSNHL), which the Company estimates to be the most frequent type of ASNHL. In addition, Auris Medical is preparing a Phase 2 trial with AM-111 in the treatment of surgery-induced hearing loss (REACH).
