"We are very pleased to obtain patent coverage on our AM-125 nasal spray program also in Japan, one of the largest pharma markets world-wide," commented Thomas Meyer, Altamira Therapeutics' founder, Chairman and CEO. "To date, we have secured patent coverage for AM-125 in more than 50 countries worldwide, including key markets in North America and Europe. Through collaboration with appropriate partners, we intend to bring AM-125 to the many patients worldwide who are suffering from dizziness."

About Betahistine

Betahistine, a small molecule structural analog of histamine, acts as an agonist at the H₁ histamine receptor and as an antagonist at the H₃ histamine receptor. Unlike histamine, it crosses the blood-brain-barrier. Betahistine is known to increase the release of histamine, acetylcholine, dopamine and norepinephrine in the brain. It increases cochlear, vestibular and cerebral blood flow and facilitates vestibular compensation and inhibits neuronal firing in the vestibular nuclei. Betahistine for oral administration is approved in about 115 countries (with the U.S. being a notable exception) for the treatment of vertigo and Meniere's disease. Despite its good safety profile, the clinical utility of orally administered Betahistine is limited due to poor bioavailability.

About AM-125

AM-125 is an intranasal formulation of betahistine. Because of its ability to circumvent first-pass-metabolism, AM-125 has been shown to have 5-to-29 times higher bioavailability than orally administered betahistine. Altamira Therapeutics has been developing AM-125 for the treatment of acute vestibular syndrome (vertigo). With its incidence and prevalence increasing with age, vestibular dysfunction affects more than one third of the U.S. population 40 years of age and older.
