Hi, Alethia. It's Steven. So, you do allude to something we see in graft-versus-host disease, not only across the world, but even within the United States and even within cities themselves, there are treatment differences in patterns at bone marrow transplant centers and how people have treated this condition to date and continue to, both in terms of preparative regimens and actual regimens, which is exactly why for best available therapy we have to account for a number of therapies. So, there's no dramatic differences across the world compared to just, as I said, even within the US itself. We always, as a matter of course, do analyses and look at differences if there are any between different parts of the world to explain response rates, et cetera. So, those analyses will be done. Typically, you do the US, Western Europe and rest of world analyses and we'll look at those. But nothing to be concerned about.
Hervé Hoppenot : Yeah. Regarding the cycle, the sort of medium to long term cycle of the business, obviously, the growth of Jakafi in the US is very key to the entire P&L of Incyte. As you can see, this quarter, Incyte is growing even faster than the previous one versus last year. And our Q3 last year was a little bit lower maybe than it should have been. So, the ratio of the 25% growth for Jakafi US maybe slightly higher than the true trend. Although the year, I think we are more in the 20%, which is still very, very strong for sort of a seventh, eighth year of commercialization. And we see a lot of potential for continued growth of Jakafi in the US in MF. It is still volume growth. Patient volume is increasing in MF. And in PV, as we said, there is larger potential for two reasons. It's because treatment rate is still on the low end, below 50%, and the duration of treatment for every patient studied on Jakafi is very much longer than what we have in MF. So, what we see is sort of chronicization of the disease in MF that is leading to this growth potential that is obviously higher. We are not changing the long-term guidance very frequently, but we have made a lot of progress throughout the number that we gave a few years ago of 2.5 to 3, and that's something we are very confident in. Regarding the P&L itself and the margin, as Christiana said, we are investing in R&D based on the quality and the required work for the assets that we have. And so, it may be fluctuating, as you have seen. When epacadostat did not work as planned, to say the least, you could see that it has a positive impact on the R&D, which is obviously the paradox of our industry, is that if you stop a project, it will improve margins. But, obviously, our goal is not to manage the margin short-term proactively, but to maximize the value to the company and the shareholders by doing the right clinical development for each of the assets that we have in our hand. At the same time, you may have seen, from 2014 to today, is that we are in the trend of improving ratios in the P&L where the growth of the top line has been not every single quarter, but on – if you look at it on a cumulative fourth quarter in a row, that margin has been improving over time. And that's why we're where we're today, the P&L has the shape that it has to today. So, that's something we will continue to look for, but it may include quarters where investment will increase because some of the assets that we have are requiring an increased investment at some point. So, overall, the way we have been sort of looking at this is, certainly, growth of the top line is driving our ability to invest in R&D and they are the two components to create value that will be sustainable for the long term for Incyte.
