So I hope it's conservative. But if you look at the current clinical trial activity out there, sites can enroll 0.3 patients per site per month per trial. So in fact, our base -- we are using that metric to set our enrollment criteria. You can expect that I have been beating up our clinical team saying it's got to be shorter than that. But through them and their experts or the people they are working with in the CRO, people are saying, man, it's jungle out there. And remember, you're talking about -- we're talking about mild AD. Mild AD is probably about 40% of AD. So that's around -- about 2 million patients total. So we have actually designed the clinical trial in a way to incentivize patients to join. What are those incentives? I mentioned them in the talk. One of them is it's 2:1 random dose. They have a 2/3 chance of getting drug versus only a 50/50 chance is someone's doing a typical 1:1 randomization. There's also companies out there that are doing open-label trials with -- where everybody gets drugged. Now that's great for the patients because they know they're getting enrollment. It's difficult to understand what's happening with the therapy. The second thing is because it's only 6 months, we then give them another 12 months of therapy, whether they're on the placebo group or not. So we think that -- and we've been told by our clinical sites that, that is a very attractive aspect because remember, the average age of an Alzheimer's patient is 71. So that means the primary payer is Medicare. Medicare, for all practical purposes, has a 20% copay. I don't know what Biogen is going to be doing with that 20% copay. There's lots of strategies that companies use to manage copays. But the fact is at $56,000 a year, plus MRI scans, plus 12 infusions, the cost of therapy is going to be more than $56,000. So the patients are going to have to come up with somewhere between $10,000 and $20,000. We're hoping that between our -- with our incentives, with the fact that they get a different approach, the fact that we are educating clinical teams about why the drug is an attractive strategy, that's why we were at AAIC, it was all about clinical team education, we hope our enrollment is faster. But one thing I've learned in this business, if I promise you enrollment in 6 months and it takes 6 months and 2 weeks, I get called on the carpet. So my clinical teams, our CRO says it's going to take a year. I hope it's less, but that's what I'm presenting. I hope to surprise you with a shorter trial.
