The other fact base that we look at is in terms of the step down is we look at other analogs and we look at the Cosentyx Taltz analog or Taltz was advantage in ESI for Cosentyx back in 2019. And we see that typically in this category, almost 90% of the erosion tracks within the first two to three weeks. And that's actually what we're starting to see, we believe with the CVS template following that similar pattern.
