Auris Medical Reports Top-Line Results from Phase 3 Trial of AM-111 in Sudden Deafness

  • HEALOS trial did not meet primary efficacy endpoint  in overall study population
  • Clinically and statistically significant improvement in subpopulation of patients with profound acute hearing loss
  • Conference call scheduled for today to review HEALOS data, provide a business update and present third quarter 2017 financial results

Zug, Switzerland, November 28, 2017 - Auris Medical Holding AG (NASDAQ: EARS), a clinical-stage company dedicated to developing therapeutics that address important unmet medical needs in otolaryngology, today announced top-line results from the HEALOS Phase 3 clinical trial of AM-111 in severe to profound sudden deafness. Overall, the HEALOS trial did not meet the primary efficacy endpoint of a statistically significant improvement in hearing from baseline to Day 28 compared to placebo for either active treatment groups. However, a post-hoc analysis of the subpopulation with profound acute hearing loss revealed a clinically and statistically significant improvement in the AM-111 0.4 mg/mL treatment group.

"For many patients, sudden deafness is a very frightening experience and may result in chronic hearing loss as well as a significantly reduced quality of life," commented Hinrich Staecker, MD, PhD, Professor, Department of Otolaryngology Head and Neck Surgery, University of Kansas Medical Center, Kansas City. "This is a challenging condition especially in case of profound hearing loss, where the ear is almost or completely deaf and the prognosis for recovery tends to be poor. I am pleased to see that in the HEALOS trial AM-111 showed promising therapeutic benefits in this group of patients who are most in need of them."

" The read-out from the HEALOS Phase 3 trial with AM-111 in acute inner ear hearing loss is a major milestone for Auris," added Thomas Meyer, Auris Medical's founder, Chairman and Chief Executive Officer. "Although the trial did not meet our expectations for the primary efficacy endpoint in the overall study population, we are very pleased to see the clinically and statistically significant treatment effect in the profound hearing loss subpopulation. Considering the high unmet medical need, we look forward to discussing with regulatory agencies the next steps on our path to bringing AM-111 to patients. On behalf of our team at Auris Medical, I would like to extend my sincere appreciation to the patients and investigators involved in this trial."

The HEALOS trial is a randomized, double-blind, placebo-controlled study evaluating the efficacy, safety and tolerability of AM-111. The trial was conducted in several European and Asian countries and enrolled 256 patients suffering from severe to profound sudden deafness within 72 hours from onset. Patients were randomized in a 1:1:1 ratio to receive a single dose of either AM-111 0.4 mg/mL, AM-111 0.8 mg/mL or placebo, administered into the middle ear.

The hearing improvement at the three worst affected contiguous test frequencies at Day 28 was 38.4 dB for patients in the AM-111 0.4 mg/mL group compared to 33.4 dB for the placebo group (p=0.226). For patients in the AM-111 0.8 mg/mL group the improvement was 36.6 dB (p=0.448). Post-hoc analysis in the subpopulation of patients with profound hearing loss[1] (n=98) showed an improvement at Day 28 of 42.7 dB in the AM-111 0.4 mg/mL group vs. 26.8 dB in the placebo group, which was statistically significant (p=0.0176). The improvement was 37.3 dB in the AM-111 0.8 mg/mL group (p=0.126). In addition, AM-111 was well tolerated and the primary safety endpoint was met. There was no significant difference in the occurrence of clinically relevant hearing deterioration between either of the active treated groups and the placebo group at Day 28.

Based on the findings from the HEALOS trial, Auris Medical has concluded that the very similar design of the currently ongoing ASSENT trial is no longer adequate for testing AM-111. Therefore the ASSENT trial will be terminated early.
