First, because he actually is taking the time to do research on the science instead of mindless drivel talking about the daily rise/fall of share price or that management sucks (new agenda now that they can't say botched trial or placebo).
Secondly, some of these publications are by 3rd party, which adds credibility to the science. One of my favorite quotes from an article reads "Acknowledgments: Dr. Philip Thorpe was a key inves- tigator being both on discovering exposed PS on tumor vasculature and development of a series of PS-targeting antibodies. Sadly he passed away shortly after comple- tion of this research. We also thank Peregrine Pharma- ceuticals Inc., Tustin, CA, for the provision of PGN635 antibody."
How many times have we heard that 3rd party validation is needed. Well it is happening at a very rapid pace now.
