Auris Medical Reports Third Quarter 2017 Financial Results

• HEALOS trial with AM-111 did not meet the primary efficacy endpoint, but showed statistically and clinically significant effect in profound acute hearing loss subpopulation
• Phase 3 results from Keyzilen ^® TACTT3 trial expected in first quarter of 2018
• Conference call and live webcast set for 8:00 am ET (2:00 pm CET) today

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 financial results for the third quarter ended September 30, 2017 and provided a business update.

"The read-out from the HEALOS Phase 3 trial with AM-111 in acute inner ear hearing loss is a major milestone for Auris," commented Thomas Meyer, Auris Medical's founder, Chairman and Chief Executive Officer. "Although the trial did not meet our expectations on the primary efficacy endpoint in the overall study population, we are very pleased to see the statistically and clinically significant treatment effects in the profound hearing loss subpopulation. Considering the high unmet medical need, we look forward to discussing the regulatory pathway for AM-111 with the regulatory agencies. In addition, we continue to focus on the development of Keyzilen ® for acute inner ear tinnitus, with top-line Phase 3 results expected in early 2018, and AM-125 for vertigo, which is preparing for Phase 1." 

Development Program Updates

AM-111 for Acute Inner Ear Hearing Loss

• Reported top-line data from HEALOS, a randomized placebo-controlled Phase 3 clinical trial with AM-111 in patients suffering from severe to profound sudden deafness. Overall, the 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 the AM-111 0.4 mg/mL or AM-111 0.8 mg/mL treatment groups. The mean hearing improvement 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 mean improvement was 36.6 dB (p=0.448).  
• A post-hoc analysis of the subpopulation with profound acute hearing loss (i.e. mean hearing threshold of 90 dB or higher; n=98) revealed a clinically relevant and statistically significant improvement in the AM-111 0.4 mg/mL treatment group. The improvement at Day 28 was 42.7 dB in the AM-111 0.4 mg/mL group vs. 26.8 dB in the placebo group (p=0.0176). In the AM-111 0.8 mg/mL group the improvement was 37.3 dB (p=0.126).  
• AM-111 was well tolerated in the HEALOS trial, 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.  
• The Company plans to discuss the HEALOS results and the regulatory pathway with health authorities. In addition, the Company will terminate the ASSENT trial early as it is very similar in design to the HEALOS trial and, based on the new findings, is no longer adequate for testing AM-111.

Keyzilen ^® (AM-101) for Acute Inner Ear Tinnitus

• Completed patient recruitment for the Phase 3 TACTT3 trial, which is being conducted in Europe. In total, the trial enrolled 741 patients; 373 patients were enrolled within the first three months from tinnitus onset (acute stage) and 368 patients were enrolled between three to twelve months from onset (post-acute stage). Auris Medical expects to announce top-line results from TACTT3 in the first quarter of 2018.

AM-125 for Vertigo

• Completed the acquisition of various assets related to intranasal betahistine from Otifex Therapeutics Ltd. In addition, Auris Medical obtained from an undisclosed party the right to use certain proprietary preclinical and clinical data that will support the AM-125 development program and future regulatory filings.  
• Received regulatory feedback from the U.S. Food and Drug Administration through a Pre-IND meeting and from two European health authorities. The feedback is being incorporated in the Company's development plans for AM-125, including the planned second Phase 1 clinical trial with AM-125. The study is expected to start enrolling patients during the first quarter of 2018 and will seek to determine the maximum tolerated dose with single and repeated dosing.  
• Hosted a symposium, Targeting Histamine Receptors for Vertigo Therapy , during the American Academy of Otolaryngology-Head and Neck Surgery Foundation Annual Meeting & OTO Experience on September 11, 2017, in Chicago.

Corporate Developments

• Executed share purchase agreements with Lincoln Park Capital Fund, LLC for up to $15.0 million to provide additional operational flexibility.

Other Developments

• Thomas Jung, MD, PhD, who joined Auris Medical in 2016 as Chief Development Officer, has decided to leave the Company by the end of the year to pursue a new career opportunity.    

Third Quarter 2017 Financial Results

• Cash and cash equivalents at September 30, 2017, totaled CHF 20.2 million.  
• Total operating expenses for the third quarter of 2017 were CHF 5.6 million compared to CHF 7.5 million for the third quarter of 2016.  
• Research and development expenses for the third quarter of 2017 were CHF 4.2 million compared to CHF 6.3 million for the third quarter of 2016.  
• General and administrative expenses for the third quarter of 2017 were CHF 1.3 million compared to CHF 1.2 million for the third quarter of 2016.  
• Net loss for the third quarter of 2017 was CHF 6.0 million, or CHF 0.14 per share, compared to CHF 7.9 million, or CHF 0.23 per share, for the third quarter of 2016.

The Company expects that its operating expenses in 2017 will be lower than the previous guidance of CHF 28 to 32 million and that existing cash and cash equivalents will enable the funding of operations into the second quarter of 2018.
