Obviously if you have researched you understand there are many others working in some way with RNAI technologies at various stages of potential success, some with major JV partners either contributing or waiting and watching to pounce. All regardless appear to believe the science to be good, just the method of delivery, the problem being targeted, and likely results in question.
Why not let these smaller fish who have specialised in targeting this technology do the heavy lifting for you until safe, validated and starting to producing desired results before you spend the big bucks either owning or majority controlling what is output and for what price and profit ? And that could include buying out anything that may be seen to be too good, reducing the problem too much and thereby decreasing ongoing profit ?
That said no matter what, mother nature has a habit of developing bigger and better or more resistant strains etc.. And sadly if they don’t, we’ll maybe there are those in science who stand to loose the most, who might just make sure it happens ?
