Good morning, Marc. It's Rich. Yes, I laughed when you said normal timeline for arbitration, there's a contractually provided window for arbitration. But we've seen in previous examples, where it can be effectively irrelevant. We don't think that anything is going to materialize before six months. But it really is up to the arbitration panel for how long it takes. So we've had more specificity on that for you. This, the Nektar failure has actually given us an opportunity. It's not like we've not been talking about Nemvaleukin with potential strategic selling, that's almost an ongoing dialog as people watch the data emerge. What it's allowed us to do is have the kind of conversation we're having today, which is to focus teams back on the differentiating features, which you would think that people had already highly identified. But no, it's amazing how many companies as well as investors have lumped all the IL-2s into one into one basket and said, well, if one works, and they're all going to be good, if one's bad, they're all going to be poor. Now it's forcing a real distinction. And looking at the different who remains, what products remain, where are they in development? And what are their particular features and one of the real virtues of Nemvaleukin is not just only as molecular design as pharmacology, is the fact that we've been in the clinic long enough where we have durability data, you can actually see one of the hallmark features of IL-2 which is durability for those who respond that those responses can be long-lived. And that's exactly what we're seeing through our program. That's why we continue to present data even from our ARTISTRY-1. So -- what -- when you call the backups, I really don't think of a backup, I think that the alternative dosing regimens will end up being fundamental, foundational for the broader clinical use of the drug. As you mentioned, we're testing both SubQ once weekly. And we're generating responses SubQ once weekly. The question on the SubQ once weekly is do we mimic the same durability that we see with the IV. And on the IV, we have a less frequent IV regimen that we're testing now in Bayesian design, because we're quite confident that daily IV times five, the original proleukin regimen is not necessary in order to drive the right pharmacodynamic response. So we're testing a range of less frequent doses. And our hunch is that -- is that one or more of those are going to prove to be the ultimate, most commonly used commercial dose. And we're enrolling in those studies. And as Sandy said, we'll expect maturation summit data toward the end of this year, early next year.
