I am not arguing against Bavi, far from it, I have a huge investment in PPHM and don't believe in throwing away my money but prudently risking it. I was only saying that before the FDA approves Bavi it may require a more robust profile. If you are saying that all humans are the same in regard to PS exposure and Bavi targeting and they can convince the FDA of that fact then the point is moot. Perhaps you know of a drug that was P3d in a foreign country(ies) and approved by the FDA without a trial here in the USA so we can make a comparison and see if there is ample precedent. I am just leery of the FDA.
