Auris Medical Announces Completion of Interim Analysis in Post-Acute Tinnitus Stratum of TACTT3 Trial with AM-101

ZUG, Switzerland, March 10, 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 the completion of the planned interim analysis in the post-acute tinnitus stratum of the TACTT3 trial ("Stratum B") with AM-101 and that enrollment could continue since the pre-specified futility threshold was not reached. Based on recommendations by the Independent Data Review Committee, the inclusion criteria will be adapted in order to focus on the early post-acute stage where higher levels of activity were observed than at the later stage. Accordingly, Stratum B will continue to enroll patients with tinnitus having started between 3 and 6 months prior and stop enrollment of patients with onset 6 to 12 months prior. The TACTT2 trial and Stratum A of TACTT3, which enroll patients with tinnitus up to 3 months from onset and were not part of the interim analysis, will continue unchanged.

The interim analysis on Stratum B of the randomized, double-blind, placebo-controlled European TACTT3 trial was performed based on 150 study participants (50% of the planned total) completing their second follow-up visit on Day 35. Futility was assessed since AM-101 had never before been tested beyond the acute stage of tinnitus (up to 3 months from onset). The evaluation was based on the primary efficacy variable of the trial, improvement in subjective tinnitus loudness, as well as on improvement in the Tinnitus Functional Index.

"We are very encouraged about the positive outcome from the interim analysis and look forward to continuing Stratum B to explore AM-101's therapeutic benefits in the post-acute stage", commented Thomas Meyer, Auris Medical's founder, Chairman and CEO. He added: "The outcome lends further support to our approach of treating inner ear tinnitus early, while the symptom is still of peripheral rather than central character." Bettina Stubinski, Chief Medical Officer of Auris Medical, stated: "Although accumulating evidence points to the benefits of early treatment, therapeutic benefits may still be possible to achieve even at later stages. The full analysis of outcomes from Stratum B will provide us with important further insights into the therapeutic time window for AM-101 and the natural history of inner ear tinnitus."

About acute inner ear tinnitus

Tinnitus, the perception of sound without external acoustic stimulation, is a symptom common to various ear or other diseases. (Inner ear tinnitus may be provoked by various injuries to the cochlea, the organ of hearing, such as overexposure to noise or inflammation. It may be short and just transitory; however, it may also become permanent. Tinnitus of less than three months of duration is considered acute, while older tinnitus is considered chronic.

Inner ear tinnitus may be only a slight nuisance, but often it has a serious impact on the ability to sleep, relax, or concentrate, or it may lead to tiredness, irritation, nervousness, despair, frustration, or even depression. As of today, there exists neither a universal standard of care for acute inner ear tinnitus, nor a truly proven, effective treatment method.

About AM-101

AM-101 is a small molecule N-methyl-D-aspartate (NMDA) receptor antagonist formulated in a biocompatible gel for intratympanic injection. Emerging evidence suggests that NMDA receptors in the cochlea play a major role in the occurrence of tinnitus following inner ear excitotoxicity, which is characterized by excessive synaptic release of glutamate, the principal neurotransmitter in the auditory system. Cochlear excitotoxicity may be triggered by, for example, exposure to excessive noise, neuroinflammation, disturbances in inner ear blood supply (anoxia/ischemia), or the administration of certain ototoxic drugs. It has been proposed that the upregulation of NMDA receptors induced by cochlear excitotoxicity is responsible for aberrant excitation of auditory nerve fibers, which is perceived as tinnitus.

The development of AM-101 is based on research conducted at the INSERM Institute for Neurosciences of Montpellier, France. The clinical development of AM-101 was initiated by Auris Medical in 2007 and comprises three completed clinical trials to date. Currently, two pivotal trials with AM-101 are ongoing in North America and Europe (TACTT2 and TACTT3). In 2013, Auris Medical reached agreement with the US Food and Drug Administration (FDA) under a Special Protocol Assessment (SPA) for its pivotal TACTT2 study. Patents have been granted in more than 40 countries worldwide so far.
