Love how positive this board is... but what are the risks that Kevetrin is toxic or not as effective in humans? I have a big position but I'm a bit hesitant to add more shares. I get the sense from this board that people at 99.9% sure that the treatments are going to work (almost like there is no risk they won't).

I just saw that GALE reported (yesterday) that their phase II cancer treatment worked and their stock is only around ~2/ps. I hope you're all right with a huge pop but it seems we're setting each other up for disappointment. I'm hoping I'm wrong but can someone bullet point why my risk logic is off?
