Yeah. So, for FLT3 disease, this is certainly a highly resistant type of disease and, certainly, also then results in patients being refractory or having early relapse or late relapse. So, you would expect to see patients with FLT3 mutations in the relapsed and refractory population. We think that we would expect to see some of those patients in the Phase III trial and we will have that in the data set and would expect to assess that patient population in subgroup analyses to report what we see. We also think that the uproleselan could very well be paired with FLT3 inhibitors. There's several that’s now on the market and also in trials, and this could reasonably be paired with those to improve and deepen the response seen with FLT3 inhibitors. So, we'll look at patients both in the context of the Phase III trial in relapsed/refractory disease and we will look at opportunities to put this together with inhibitors in subsequent trials. With regard to screening or gating for enrollment on the E-selectin ligand, we have remained very confident that we've seen, in our data set, all patients we've assessed, all patients in our trials who we have assessed for the E-selectin ligand, we've seen expression of the ligand on their blasts. So, we believe that it is relevant to all patients. And, therefore, we don't see a need to gate for enrollment in the trial. We also agree that this it is an interesting finding and one that we would, we think, shows strength in the correlation with remission, strength in terms of giving confidence in the outcomes that we're seeing based on the mechanism of the drug. We will assess the E-selectin ligand in the context of our Phase III trial. And so, we will have that data and have an opportunity to look at subgroup outcomes and correlate with expression, but, again, we don't feel that that is necessary for gating. I would point out one other thing, and that is that there are other benefits seen with uproleselan beyond achieving remission. So, while we think remission is important and we see that we've gained confidence in the mechanism with these data, we also see that the ability to be medically well enough, to go on to consolidation, to then deepen remission and consolidation with the addition of uproleselan, and to generally improve the response, but also maintain the patient in health well enough, for example, with reduction in mucositis, you would see them then go on to transplant at a higher rate and you would expect all of those things to improve the overall survival outcomes beyond just the remission rate.
