Thanks, Emma. Graham, so the short answer is yes and yes. So if we do it ourselves, it's financially attractive. We can also do it with a partner and I think make that work. I think our preference is to do it ourselves because of the synergies with Benlysta and various other [indiscernible]. I mean in the U.S., we are -- if we do get dialysis, and assuming we don't have an onerous REMS program, and I think you're going to see the product evolve in 3 phases. The first phase, which is about 9 months based on CMS cycles, is pre-TDAPA. I don't think you'll see much volume at that point because you're competing with EPOs, which are embedded in the bundle. Then the TDAPA period which will run for about 2 years, and that is essentially where the cost, of course, of the medicine is removed from the bundle. And so there's a strong incentive deliberately created by CMS for the large dialysis organizations, which dominate about 80% of the market in the U.S., to utilize this drug because, of course, the allowance that they have for EPO will be removed from the bundle. The amount they receive for the bundle will not change. So there's a heavy volume incentive for them. That period will run from -- based on our timelines, October 1, 2023 to September 31, 2025. After that, when it goes back into the bundle, it's very much going to become a volume contracting game in direct competition with EPO, biosimilar EPO. So a tougher game. Now all of these elements with dialysis don't require large field forces. This is going to be a very concentrated group of people that I could probably count on 2 hands, maybe take one of my shoes off. So a very small infrastructure involved there, for what is net-net from a P&L point of view, quite an attractive asset. For Europe, we expect to get the broader label. And of course, that's more of a classical non-dialysis build profile. But again, we can embed that with the Benlysta team. And I'd just direct you towards the performance of dapro in Japan, where there's 5 HIPs. It was not the first to launch, but has captured 60% and growing market share. So we think we've got a very competitive profile versus roxadustat in Europe.
