Yes, sure. I mean, first, just on erosion, obviously, would be hard to do any better than this. But I think that the minimum clinically important differences, as we've discussed, is 5 points here, we have over 20 points we could have significant erosion and still have a very compelling data set and a very compelling product profile for patients and physicians. That said, I would also note this was -- it was the U.S.-only study, but 15 sites for the 31 patients. So this was a multicenter, multidose, placebo-controlled trial, very rigorous for a smaller proof-of-concept study. So while I think that there's always some risk of erosion in particular, while the very low placebo rate is consistent with natural disease course, you can never be sure of the behavior of placebo and these inflammatory disease trials, particularly when you move to larger global trials. But broadly speaking, I think this data gives us an incredible cushion to still have an effect size in Phase III that maybe is large or maybe is not quite as large, but still would be extremely compelling. As far as the design of the Phase III in terms of size, I think we would probably be looking at a sort of similar size per arms to the DM trial roughly, but we need to kind of take this data into consideration and think more about the powering and have final discussions with FDA on it, including as related to the in indication safety set that they would want to see to support approval. So we'll have more to share on that after we engage with FDA. And the same is true on dose, I would say that I think our incoming hypothesis to this trial is that 45 milligrams based on the totality of the 1,500 patient data we have, a very compelling potential option for these patients balancing benefit and risk. And certainly, I would say, in totality, this data reinforces that, you see really excellent efficacy results from the 45-milligram arm, including on some of these higher bar, more stringent endpoints, starting to see real separation with 15 milligrams. And then certainly, in terms of the safety data, nothing that would suggest the overall safety profile of 45 milligrams that we've seen across all of the different indications in which it's been studied, that nothing in this data to suggest there's anything specific to cutaneous sarcoidosis separate from those. So I think broadly speaking, I would say we're very excited about 45 milligrams coming into the study. We're even more excited about it coming out of the study. 15 milligrams also performed very well, and that's great to see. It really just speaks to the overall efficacy potential of the product. And so we'll kind of have a final update on that after we engage with the agency.
