Hear from an expert on what have you learned from your experience with biologics?

My patients who had tried everything, they had the worst polyps -in the earlier clinical trials, we did not know that this would even work, we were very skeptical, and so when patients came back to us a week or two after their injection, and they were saying that they could smell again after they hadn't smelled anything for decades, it's quite a remarkable thing. But not only that, the patients believed in this, they could immediately sense that something was happening to them that they had never experienced before with surgery or with medication, so it was quite inspiring to see that process.
