I agree that the poison pill advantages outweigh the disadvantages, and this, I believe.... it 100x more true when we are talking about a paradigm shifting evolution in biotech such as Immunotherapy.
The core of immunotherapy is to place the immune system back in control and ironically, Big Pharma would not have made Billions of dollars from the beginning of its time if someone knew how or controlled the IP that allowed the immune system to shift back in control of fighting diseased cells and cancers.
Of course they had to take a chance or someone had to take a chance in sabotaging Peregrine.... the stakes are too high and they remain high.
Happy Easter to all and what shall Peregrine and K&L Gates come out with next is what we wait for next I would think
