Sure, and most miracle drugs don't pan out. Yet there is some reason to at least hope this is a little better than arsenic - it didn't kill the mice nor dogs, and there are various plausible sounding claims about toxicity made (to a non-expert, I just googled the various methods and showed the paper to cancer-researching friend that didn't immediately cry foul).

I mean, the track record of such drugs still suggests it'll likely not live up to the hype of the title here, but that's the point of further research, which does appear to be happening. It's quite likely there's some unforeseen limitation, but hey, we can always hope.
