Thanks, Umer. Great questions. On the competitive front in prevention, I think you talked to our competitors at a recent release of atogepant. Of course, everyone has to be careful of cross-trial comparisons. What we'll say there is if you just plot out the efficacy of all the oral as well as the mAB agents in prevention, I think you're going to see somewhat of a similar story and magnitude of effect. And what you see changes is placebo rates, right? So when you're hitting the target, what this teaches us is that you get robust efficacy. And if you look at the magnitude of our effect, we had one of the largest magnitude of effects in the prevention space. And so we're quite encouraged by that. But then some differentiation there, it's a very different profile on some safety measures, such as constipation. As you recall, we did not have any signal for constipation with regards to Nurtec ODT, and that was very different than at least two of our competitors where that's a signal that's being picked up. I really believe that's the benefit from our intermittent dosing and giving a differentiated profile there. And then also highlight, we are the only company with this dual-acting strategy. If we're successful with our prevention, we will be the only one that says 1 pill, same dose, acute and prevention, big differentiation point in the marketplace, big win for patients in the simplicity as well as payers, right? You don't have to then pay for 2 different segments here. It's going to give us a lot of opportunity to work with payers to make sure that this approach is accessible to patients and cost-effective. Finally, zavegepant intranasal is our lead. But yes, we're now, for the first time kind of talking more about our total program with zavegepant, including an oral version. Actually, we have 2 different oral versions, and we're excited to take that into a number of nonmigraine indications, and you'll be hearing more about that. We won't be giving more details today for competitive reasons. But the zavegepant program, you're going to see branch out in different directions, not just in migraine and pain. And so that's why as Elyse said earlier, we talk about our CGRP antagonist as a franchise. We have so many multiple indications in migraine adjacencies as well as multiple compounds. And I'll turn it over to BJ for the first half of the question.
