Sure. So thanks for the question, Geoff. Let me start with first-line lung, because I think that's probably on a number of folks' mind. The lung launches are going very well and in fact are tracking at or maybe even a bit ahead of our expectations. Let me highlight just a few things. From a share standpoint, it's still very early days, but share is currently in the mid-single digits and we've seen very good momentum in the uptake here. Importantly, we've seen uptake across all PD-L1 segment, as well as across histology. And the uptake has been particularly good I would say in the PD-L1, one to 49 segment. As expected, given the timing of approval and the relative immaturity of the data, the uptake of the 9LA regimen has 227. However, in recent weeks, we've even seen an uptake in the use of dual IO with chemo. And again, this appears to be across subgroups. So, good momentum on utilization. Execution has been particularly good, especially given the dynamics of COVID. Most of the engagements remain virtual. But we're seeing very good engagement between the sales force even in a remote environment with key customers. Physician reaction has largely been aligned with expectations in our previous conversations with depth and durability of response of these agents with a manageable safety profile being the primary message. So what I would say is it's still early days, but we're very happy with the utilization that we're seeing. We've got good execution, physician reaction continues to be positive. And we're very pleased that in spite of entering first-line lung as the third company to market our shares. Now after eight weeks are putting us as having the second most widely used regimens in the space. And as it relates to the growth, as Giovanni mentioned, we still see Opdivo as a growth brand going forward. The fundamentals of the business today continue to be relatively strong. We've got relatively stable base of business in the U.S. The second-line lung dynamics continue to play out as we had expected both in the U.S. and ex U.S. The early launch and lung is performing well. And we've got good fundamentals ex U.S. And then if you think about 2021, with the strong 9ER data that we talked about in the last quarter, we feel really good about the growth opportunities that we see for Opdivo starting in 2021. With respect to TYK, very excited, obviously about the data that we have already presented with Phase 2 and psoriasis, psoriatic arthritis, Phase 2 data is we think if it plays out in the Phase 3 going to be compelling. Remember, this is a disease area that's large, over 2 million people are diagnosed in the U.S., EU5 in Japan with psoriatic arthritis. And there's still significant unmet need here. Two-thirds of the patients, for example, who are stable on DMARDs, continue to have disease activity. And there's considerable dissatisfaction with existing oral agents when you look at the totality of the profile, both efficacy and safety. So, obviously, early days, but we're excited about what we're seeing there.
