>>> From strictly a bureaucrat's point of view, it is possibly to argue that survival results from a single trial where survival was not the endpoint is really a surrogate for confirmed survival proof. <<<
You've got it just exactly backwards. What the bureaucrats have given us is a bunch of oncology surrogate endpoints with a mediocre record , or no record at all , of correlating to clinical benefit.
The endpoint we're interested in here is death , not survival . Survival is the beginpoint. No surrogate marker will ever correlate perfectly with the future time of death of a cancer patient. The only ones that would even have a chance would be things like a flatline on an EKG , or maybe the buzzards , and they're no good because they don't save any time in running the trial , which is the whole point of surrogates in the first place.
Statsig improved survival in a single well-controlled Phase 3 trial , in which survival is not the primary endpoint , is a better "surrogate" for survival than any other surrogate ever will be. Only someone with a bureaucrat's point of view fails to see that.
