Thank you, Lucy. I'll try to cover all your questions. So I'll start with RUCONEST and your questions related to the delisting of RUCONEST in some countries in Europe. We plan to complete this by the first half, first quarter -- end of the first quarter, first half of next year. When it comes to -- and again, this is really driven by the fact that we don't see the commercialization of RUCONEST in these countries that's financially sustainable. Given the number of growth drivers that we have, we hope to be financially disciplined and ensure that we deploy our capital appropriately. Obviously, we are working with all stakeholders in those countries to ensure that those patients will be able to access the right treatment and if needed, ensure continuity of supply of RUCONEST through compassionate use access mechanism. When it comes to Ekterly, I mean, I said that clearly, for me, the RUCONEST and Ekterly are serving 2 different types of patients. And as such, I don't see a second threat for RUCONEST. I mean, RUCONEST is a drug that has a unique mode of action that replace the missing or deficient protein underlying the biology of the disease. RUCONEST has a very unique mode of administration that allow a very fast onset of action. And as such, it has a unique value proposition for more difficult-to-treat patients. That's why the vast majority of patients on RUCONEST are more severe patients, are patients that often have failed other treatments, are patients that need actually that level of efficacy, that speed of onset to really address their more frequent and more severe crisis. All right, moving to Joenja and your question about the U.S. as Anurag said, test labs are in ongoing conversations with the researchers, which published this paper in Cell. And we expect that over time about 20% of the U.S. patients to be reclassified as APDS. We have obviously to remain arm length, obviously, to what's happening and hope that the discussion will progress well and that we will see some patients being reclassified. Outside the U.S., the process will be the same. Test labs will have to, again, understand the data, incorporate the data, identify patients who are carriers of those newly identified variants. And if those test labs feel that those patients needs to be reclassified, then they'll call the doctors and then the doctors will probably reach out to the patients. The adherence rate is -- we don't see any change actually in the adherence rate for Joenja. It is actually remains extremely strong and around the magnitude that you have mentioned. When it comes to patient identification, you're right that we're very pleased to see that our efforts continue to pay off and that we have added 13 new APDS patients in Q3. We have identified 13 new APDS patients in the U.S. in Q3. That shows our capability to identify patients in this ultra-rare -- suffering from this ultra-rare disease. You asked about the peak. I mean, there are in the U.S., if you consider the prevalence, at least 500 patients suffering from APDS. On top of it, we've said that we expect that 20% of the U.S. patients actually could be reclassified as APDS, and that could increase the potential of this population by 50%. And then on top of that, Anurag mentioned the efforts that we are making to really leverage the work that has been published in sales and which suggests that APDS prevalence may be far higher. And that could be actually an upside. So again, I think there are some very concrete numbers I've shared with you. And on top of it, the potential upside, which we cannot quantify today. The authors suggested up to 100x. Again, this needs to be verified, and you can see that we have a very concrete and solid kind of action to be able to come back to you with more next year. I hope I addressed your question, Lucy.
