Empowered Patient Podcast Restoring Olfactory Function After Post-Viral Loss of Smell with Rick Geoffrion Cyrano Therapeutics
Rick Geoffrion, Founder and CEO of Cyrano Therapeutics, is developing a drug to restore olfactory function due to post-viral loss of smell and taste. As a result of COVID-19, there has been a significant increase in the number of people affected by long-term smell and taste loss, with no effective pharmaceutical options previously available. Smell loss can also be an early indicator of neurodegenerative conditions, suggesting future applications of the intranasal spray that aims to directly restore function to the olfactory receptor neurons.
Rick explains, "Taste and smell have a really strong connection, actually. First of all, they're two out of the five basic senses that we have as human beings. When you lose your sense of smell, people actually perceive that they've lost about 80% of their sense of taste. Now, technically, you're not losing your sense of taste. We actually just give our tongue too much credit. Our tongue is able to detect sweet, sour, salty, bitter, and umami. That's all it detects, and it detects them really in light monotone that are about 80% less intense if you've lost your sense of smell. In addition, if you no longer have your sense of smell, what you've really lost is the ability to detect flavor in food. So, to tell the difference between a peach, a pear, and a strawberry, maybe you'll tell that visually, but to tell it from a flavor perspective, you completely lose that ability.
"There really are no significant therapies to treat the condition right now. Essentially, if you've lost your sense of smell, a physician may recommend that you use smell training, which is essentially the regular smelling of intense essential oils, and they really haven't been shown to significantly treat or cure a chronic smell loss condition. It is thought that if your body is spontaneously recovering, say within those first few months, if you do undergo smell training, you may accelerate that recovery. But other than that, there's certainly no gold standard treatment or no significant treatments available right now, and no pharmaceuticals in the pipeline other than CYR-064, which is being developed by Cyrano."
