Well, Ozark, I agree with the possibilities as you see them but to me it seems premature to buy again. Been burnt by adding 2 + 2 and the result turns out not to be 4. Perhaps the wrong arithmetic, which in this analogy is how Prochymal works, is being applied. I don't know. I will be watching developments, though, and would buy again with more signs that some passage like that you foresee is really developing.
