narmac,  there must be very very good reasons why Pfizer, BMS  Merck,  the NIH, Dana Farber and Cleveland clinic have decided to do Clinical collaborations with Zenith for all their trials  and pay full pop all trial cost,  I am not sure that would happen if there was not very keen interest in Zenith for  a partnership deal or buyout at some point in time, DM will be gone at some point , he aint no spring chicken but i have faith the science will carry this company
