“We're confident things are tracking in line. We're quite interested in this shift to other mechanisms, which is frankly somewhat anticipated, but maybe operating a little higher than we thought, and we still believe that a significant majority of Humira will see it at parity lives in '24.”

In context

“nd that's really not different now. So when we look at the structure and controls of our existing agreements, we do not see widespread exclusions for the rest of the year, as we go forward. And so I think we've been pretty consistent with that that select clients will move towards biosimilars over the course of the year. Last year, we saw that with Kaiser and Medicaid plans. We talked about the CVS exclusion for the template business. And we do see that some select plans may take another approach, which we've contemplated as the year goes on, which is they may move new patients to the biosimilar, but maintain the large existing base. And that's quite manageable because really only about 14% or 15% of the patients are new patients that cycle into Humira. So overall, that's our perspective. We're confident things are tracking in line. We're quite interested in this shift to other mechanisms, which is frankly somewhat anticipated, but maybe operating a little higher than we thought, and we still believe that a significant majority of Humira will see it at parity lives in '24. Okay. So the tail we're going to be negotiating '25. And what we've highlighted is we are going to watch exactly how the interchangeables play out. We think we've got a good understanding of that. And so it will probably become more apparent as we move through '25 where that tail may sit. And we've highlighted that it may start to emerge in '25 and probably be much more visible by '26. And that's going to ultimately depend on how over the course of '25, the price volume fully plays out in the marketplace. Robert Michael : And Chris, this is Rob. On your question regarding the guidance for this year. I think it's important to note yes, we've said that the vast majority of the erosion is price. We've talked about that dynamic. If you think about first half, second half, we have the annualiz”
