Yes, absolutely. Well, I think there's two parts to the question. The first is how well is the drug tolerated, the class of drugs tolerated. And then kind of what could be clinically meaningful in terms of an outcome from the study. I think the good news is that unlike traditional adjuvant chemotherapy, which has significant toxicities, sometimes a risk of death. I think the NSAID class of drugs, of which CELEBREX is one of them, are pretty well tolerated. It's obviously not without side effects completely, but relatively, this is a class of drugs, thousands and millions of folks are taken for other indications. I think what good looks like, I think, obviously, that's going to depend on a few things. How does the readout look in terms of DFS, in terms of OS, and how does it compare to prior studies. I think we've said in the past kind of the last study that led to an approval with a new agent was the MOSAIC study, and had a hazard ratio and kind of 0.75%, 0.77% range for DFS and a very small benefit for OS. So we do think that's kind of a good number to think about. I think CELEBREX itself in the initial 702 study without any selection, I think showed a hazard ratio of, I think, around kind of 0.8%, 0.9% range, depending if it was for DFS or OS, and it was obviously not statistically significant. So maybe kind of long answer, but I think the short of it is, we do think anything that's significant below 0.8% hazard ratio for DFS and/or OS and be significant, especially with the class of drugs that's pretty well tolerated.
