Sean is correct, if we still have people living then you can't calculate what the mean survival time is because it's getting better everyday. I think what you're remembering is that the median overall survival (mOS) was most important and at the time of the PR back in 2021, at 12 months we had not reached the mOS because more than half of our patients were still alive. At this point, with only 5 patients still alive we should be learning what our mOS was when they share the data with us.
