I would just add that for those individuals, we've made it very clear that we will not be.... In part because they haven't been to the IRB yet, we will work to schedule them. In some instances we do our own review: We make a decision that there's not enough evidence and it won't go to the IRB.
The numbers are very active, very dynamic and changing all the time, but we are very seized with addressing these issues as soon as they emerge from the IRB. It takes time for that to get scheduled, but I don't think people are stuck or in limbo prior to that. They're being protected.
