Yes. So, I think the spirit of your question, if I'm wrong, please correct me, is, are we concerned that there's too many patients dropped out that we're not going to have enough power? And the answer is no. We account for that. And, I would say that, I don't know the exact number off the top of my head, but it's less than what we expected. The most common reason for dropouts, quite honestly, is just, what you get with elderly patients. So, we're not seeing anything that indicates patients are dropping out, at a high rate due to a potential drug efficacy or safety impact. It's mostly just elderly related issues. So, I think that's a good thing. And the second thing, regarding a phase two trial, I don't know how to answer that. I think a lot of it depends on the data. It depends on, the discussion with the FDA. I mean, we may see incredible results that suggests we could power a study with 50 patients. The FDA may come back and say no, you need a larger safety database. We want a thousand patients. So, I think there's so much that's up in the air. I think it also depends on whether or not they like the EMACC. They may say, yes. Great. Do the EMACC, then we can do fewer patients. Or they may say, no. We want you to do the CDR, and we may have to power it differently. So, I think what the trial is going to look like, what it's going to cost, and when we can start is really going to be dependent on that conversation with the FDA. But the expectation is we'll we're going to move as fast as we can to get it going very quickly.
