Auris Medical Announces Positive Results From Second Phase 1 Clinical Trial With Intranasal Betahistine

Auris Medical Holding AG (NASDAQ: EARS, the “Company”), a clinical-stage company dedicated to developing therapeutics that address important unmet medical needs in neurotology and mental health supportive care, today announced positive results from the second Phase 1 trial evaluating intranasal betahistine in healthy volunteers. The study results demonstrated superior bioavailability over a range of four intranasal betahistine doses compared to oral betahistine, with plasma exposure being 6 to 29 times higher (p-value between 0.056 and p<0.0001). Further, it confirmed the good safety profile of intranasal betahistine and showed that the treatment was well tolerated when administered three times daily for three days.

The randomized double blind placebo controlled Phase 1 trial with dose escalation enrolled a total of 72 healthy volunteers. One group of study participants received a single dose of intranasal betahistine or placebo and, following a wash-out period, three doses daily for three days. Single doses were escalated up to 60 mg, and repeated doses up to 40 mg. For the latter, the maximum tolerated dose based on local tolerability was determined at 40 mg. The other group of study participants received oral betahistine or placebo for reference. Pharmacokinetic parameters in blood plasma were determined for betahistine and its metabolites, and relative bioavailability for intranasal betahistine was calculated compared to oral betahistine 48 mg, which is the maximum approved daily dose as marketed world-wide (ex US).

The Company plans to initiate two randomized double blind placebo controlled proof-of-concept studies with intranasal betahistine in the first quarter of 2019. In the Phase 2 “TRAVERS” clinical trial (program AM-125), the Company will enroll patients suffering from acute vertigo following vestibular schwannoma resection. In the next step for the AM-201 program, the Company will conduct a Phase 1 pharmacokinetic/pharmacodynamic study in healthy volunteers to evaluate intranasal betahistine in the prevention of olanzapine-induced weight gain.
