 There's really nothing about HCC that is that you can transfer over to Fibrolemolar. So AtezoBav unfortunately never works. A Seraphonib never works nor does any monotherapy. But combination therapy using immunotherapy does. So for example, we have four systemic therapies that we use commonly. One is using Gymsidobene oxalplatinum linvantanib. The other is using NIVO, Nivolumab with Gymsidobene linvantanib. And the third one, 5FU interferon with Nivolumab. So they're all combinations, first of all, at least three drugs. There's also supplements that are beneficial. And so what's interesting to me, to me, all of these therapies are very tolerable.
