As far as the psoriasis trends in the IL-17s, I think the trends you're seeing on the IL-17s is similar to what we've talked about on previous calls, and that is that they tend to be relegated to second-line and beyond. So typically, after the patient fails the first-line therapy, which in most cases is HUMIRA, then they'll go on to use an agent like the IL-17s. So I haven't seen a whole lot of change in the overall market dynamics around that. Maybe another way to think about it is to more broadly look at HUMIRA, and not just the psoriasis market but overall the market. And if you look at HUMIRA, obviously it continues to perform extremely well. It performs well because it's in big markets that are growing, and obviously the asset has the profile and our execution is such that we get the vast majority of the front-line patients moving into HUMIRA and we're able to sustain those patients over time. If you look at the overall market growth rate, it's running about 10% or 11%. That varies from mid-single digits, 6%, 7% in rheumatology to high teens in derm and GI. So those are big markets that continue to grow nicely. If you look at our Rx growth, on average, it was about 9% this quarter. Again, that varies at about a little over 6% in rheum, double-digit, 10%, 11%, 12% in derm, and GI is more like 12% or 13% overall script growth rates. The important thing in this market is to capture the front-line patients and maintain those patients over time. And so if you look at every one of the sub-categories for HUMIRA, essentially RA, SPA, PSA, AS, psoriasis, Crohn's, and UC, those are the major categories that we measure and you look at first-line capture rate, HUMIRA is number one in every single one of those. It varies anywhere from around 30% on the low end to as high as 56% of new patients capture on the high end across those categories. And so the brand continues to perform extremely well and the markets continue to perform extremely well. But there's still room for a lot of agents in this market because not all patients respond to any one agent, so you need multiple therapies to be able to put those patients in the appropriate level of control. And so the IL-17s and the IL-23s and many other mechanisms will have a role to play in the treatment paradigm for these patients going forward.
