Whereas most asthma management involves inhalers or pills or injections, this is a procedure. And so it's used via bronchoscope. We go down through the mouth. You're under anesthesia, so you're comfortable. It's the only thing that directly targets the muscle that wraps around the breathing tubes.
All the therapies that are geared towards asthma are trying to help stop the inflammation or keep you from having an allergic reaction or try to dilate the muscles so that the airways stay open. But this is the only one that tries to actually target the muscle and try to make it not work, essentially, so it can't constrict.
When it was first being developed, it seemed like a crazy concept to go in and literally mess with the airways of someone whose airways, by definition, have a disease, except the clinical data proved that it's safe and it's effective.
If you're the type of asthmatic where your doctor says, take this inhaler twice a day every day, and you do, and you're feeling great, you rarely need your rescue inhaler, you're never in the ER, you’re not needing prednisone, then you don't need something like bronchial thermoplasty. Keep taking your inhalers.
But there are enough patients out there that are on the best drugs we have, and yet they still can't play sports. They can't chase their kids. They can't climb up the stairs. They're in the ER again. They're on prednisone again. Or worse, they're always on prednisone. What do you do for these people? Historically, nothing. You said, well, prednisone. Good luck. That's not acceptable. It is a horrible drug. And so we have better choices, and that's where this procedure comes in.
