Empowered Patient Podcast Intranasal Delivery of Cancer Drugs Bypasses the Blood-Brain Barrier with Dr. Thomas Chen NeOnc Technologies
Dr. Thomas Chen, Founder, CEO, and CSO of NeOnc Technologies, is working on the challenge of delivering drugs across the blood-brain barrier by using an intranasal delivery approach to target brain cancers. This delivery platform leverages the cranial nerve to transport the drugs directly to the brain, bypassing the blood-brain barrier. Genomic analysis of the long-surviving patients in the phase one trial revealed a common genetic mutation, informing the trial design for the next phase.
Thomas explains, "So our platform is what we call intranasal delivery. And with the intranasal delivery, we're not trying to cross the blood-brain barrier. We're trying to cross over it. And how we're doing that is doing the delivery of the drug via what we call the C nerves. Now the cranial nerves are, we have 12 cranial nerves in our brain. These cranial nerves have various functions, but the cranial nerves involved with the nasal brain delivery are the first and the fifth cranial nerves. The first cranial nerve is what we call the olfactory nerve. That's the nerve that's responsible for smell. The fifth cranial nerve is called the trigeminal nerve, which involves facial sensation and allows us to chew."
"So what happens is that when we want to deliver the drug to the brain cancer, we have the patient inhale it. When the patient inhales, it goes through the nose, and through the olfactory nerve, it goes to the brain. Usually, that molecule then absorbs in the spinal brain and then circulates to the target, in this case, brain cancer. Now you know how powerful that cranial nerve is from the standpoint of what it does when you smell something, that scent, that odor gets transported from the olfactory nerve to our brain. And that's basically what we're doing. We're taking something external to the brain, allowing the cranial nerve to absorb and transport it to the brain."
