Auris Medical Announces Interim Data From TRAVERS Phase 2 Study With AM-125 in Vertigo; Says Improvement 1.9 To 2.4 Times Greater With Highest Dose Than With Placebo

  • Dose dependent improvement in balance tests over placebo in Part A of TRAVERS trial
  • Improvement 1.9 to 2.4 times greater with highest dose than with placebo
  • Trial to proceed with Part B to test AM-125 10 and 20 mg vs. placebo

Hamilton, Bermuda, September 3, 2020 – Auris Medical Holding Ltd. (NASDAQ:EARS), a clinical-stage company dedicated to developing therapeutics that address important unmet medical needs in neurotology and central nervous system disorders, today announced positive top-line data from the interim analysis of its Phase 2 "TRAVERS" trial with intranasal betahistine in vertigo (AM-125).

The interim analysis was based on Part A of the trial, which enrolled 33 patients suffering from vertigo following neurosurgery who were treated with AM-125 1, 10 or 20 mg or placebo (3 x daily) for four weeks. It demonstrated a dose-dependent improvement in balance as well as good safety and tolerability of ascending doses of AM-125. At the highest dose of 20 mg (3 x daily), AM-125-treated patients improved their performance of the "Tandem Romberg" and the "Standing on Foam" balance tests from baseline to 14 days post-surgery (primary endpoint) on average 1.9 to 2.4 times more than placebo-treated patients (6.0 vs. 3.1 and 10.5 vs. 4.3 seconds, respectively). In contrast to placebo, the improvement from baseline was statistically significant for AM-125 20 mg and for all active dose groups, respectively (p<0.02 and p<0.01 to p<0.05, respectively). These positive results were supported by similar improvements in additional efficacy measures, including additional objective as well as clinician- and patient-reported outcomes.

"We are very excited and encouraged by the good safety and tolerability as well as the strong and consistent signals of AM-125's clinical efficacy observed in this first part of the TRAVERS trial," commented Thomas Meyer, Auris Medical's founder, Chairman and CEO. "For patients suffering from vertigo, regaining balance as quickly as possible is of utmost importance. Unlike other vertigo drugs that suppress the vestibular function to treat just short-term symptoms such as nausea, AM-125 acts as a vestibular stimulant to enhance and accelerate vestibular compensation and help patients to ‘get back on their feet'. There is a strong medical need for a novel drug in this area, with e.g. 35.4% of the US population aged 40 years and older suffering from vestibular dysfunction (i.e. failing the "Standing on Foam" test).1 We look forward to advancing the AM-125 program further in order to bring this innovative nasal spray to patients."

Based on the results from the interim analysis, the two highest doses, 10 and 20 mg, were selected by the Company to be tested against placebo in 72 patients in Part B of the trial. As the Company remained blinded to treatment allocation during the interim analysis, the corresponding data from Part A will be pooled with those from Part B. The improvement in the "Standing on Foam" test will become the sole primary efficacy endpoint. This test measures how long patients are able to maintain balance on a foam mat (to obscure proprioceptive input) with their eyes closed (to eliminate visual input), relying primarily on vestibular input from their inner ears. The improvement in the more challenging "Tandem Romberg" test, which is performed with eyes closed and the two feet to aligned one after the other, will become the key secondary efficacy endpoint. Prior to starting Part B of the trial, open label testing of oral betahistine for reference purposes will be completed (n=16).
