Auris Medical Provides Update on Intranasal Betahistine Development Program
- Phase 1b trial with AM-201 proceeding as planned to data read-out in early
- Enrollment into Phase 2 trial with AM-125 impacted by COVID-19 pandemic
- Company to report 2019 second-half and full year results and provide general business update on
April 16, 2020
The Phase 1b trial with AM-201, intranasal betahistine for the prevention of antipsychotic-induced weight gain and somnolence, has remained unaffected by the COVID-19 pandemic. The last subject had its last treatment visit in early
The Phase 2 trial with AM-125, intranasal betahistine for the treatment of acute peripheral vertigo, will be impacted by the COVID-19 outbreak. The outbreak has delayed enrollment into the study. Candidates for participation in this trial undergo certain types of neurosurgery, which are classified as elective procedures. Due to the COVID-19 outbreak, the sites participating in the “TRAVERS” trial have postponed elective procedures and temporarily reduced or suspended clinical research activities. As a result, enrollment came to a halt towards the end of
The Company expects to report its 2019 second-half and full year results and to provide a general business update on
Betahistine is a small molecule structural analog of histamine, which acts as an agonist at the H1 and as an antagonist at the H3 histamine receptors. Unlike histamine, it crosses the blood-brain-barrier. It is known to enhance inner ear and cerebral blood flow, increase histamine turnover and enhance histamine release in the brain, increase release of acetylcholine, dopamine and norepinephrine in the brain and to result in general brain arousal. The compound has a very good safety profile, yet it is also known that its clinical utility is held back by poor bioavailability. Intranasal administration of betahistine has been shown to result in 5 to 29 times higher bioavailability.
Intranasal betahistine is being developed under project code AM-125 for the treatment of acute vertigo. Betahistine has been shown to increase cochlear, vestibular and cerebral blood flow, facilitate vestibular compensation and inhibit neuronal firing in the vestibular nuclei. Betahistine for oral administration is approved in about 115 countries, with the US being a notable exception, for the treatment of vertigo and Meniere’s disease.
Intranasal betahistine is being developed under project code AM-201 for the prevention of antipsychotic-induced weight gain and somnolence. Many antipsychotic drugs are known to block the H1 histamine receptor, which is involved in the control of appetite and wakefulness, resulting in weight gain and somnolence as side effects. As an H1 receptor agonist, betahistine is thought to counteract the antipsychotics’ inhibitory effects; in addition, betahistine blocks presynaptic H3 histamine autoreceptors, thus increasing histamine release and in turn augmenting betahistine’s direct agonistic effects on H1 receptors.
