Thank you for the question. I believe that we have four questions here. Let me take a crack on the first questions, and then Chin can address the 307 and the time line for clinical report. And I can probably also optimize my answer to the first question, some insight on interest of investors and partners on 307 and then, again, maybe back to Chin on asthma potential. So with respect to the opportunity of CBP-201 in the AD space, you are absolutely correct that the AD space treatment has evolved quite a bit now since loans of dupilumab. And it is now becoming a more crowded space, but if you all look at the market opportunity and the number of patients worldwide that can benefit from systemic treatments. The opportunity, obviously, is very large, and that's validated by the performance of drugs like dupilumab in the marketplace. Now when we look at opportunities, obviously, we're looking at this time, we believe that biologics, especially biologics that have significant efficacy and excellent safety profile, is going to continue to be most important and we'll continue to dominate this space as the market grow And, obviously, other modalities will have a significant role as well. Now within the IL-4 alpha receptor antibody space represented here by dupilumab, we believe that blocking IL-4 and IL-13 continue to be the most effective way of treating AD as well as other diseases, allergic diseases associated with type 2 inflammation. So if you just look at the IL-4 antagonist space, obviously, so far dupilumab is the only drug on the market right now. Connect is developing a potentially differentiated antibody as a second to the market in this specific class, right? And as we have communicated in the past, dupilumab is good, it's a wonderful drug. But certainly, in terms of its efficacy, in terms of convenience of use, in terms of dosing frequencies, there are clearly opportunities to improve and allow other molecules to come in. When we look at CBP-201, it's an entirely different molecule with different binding epitope. And our goal here is to have differentiation in perhaps a number of areas, right? So, we have potentially the overall efficacy, and we're going to find out in our user studies. And the other is potentially in the long treatment period of maintenance where -- and Q4W may be an opportunity where it's not available or dupilumab. So to kind of circle back to the question, yes, it is a crowded space. And each of this kind of category has their specific utility to address patient needs, and we believe that CBP-307 does have a great opportunity if our clinical data support a robust efficacy and potentially dose interval. The -- let me go to the question on CBP-307, as in my opening remarks here, we emphasized that CBP-307, by all the measures that we look at, looked at the totality of our Phase 2 data, we are quite comfortable that clearly the molecule is working the way it should, especially we emphasize the clinical remission rate. And there have been continued interest in CBP-307, and we have been an ongoing discussion. And at this time point, we don't have anything to update, but we will be happy to do so when we are ready to announce any sort of update on the discussion. Let me ask Chin to address the progress in terms of when our clinical report will come up and also the asthma opportunity for CBP-201. Chin?
