Agree partnering PCS could delay its move into phase 2, but that is not certain. They are still running the phase 1 but I doubt the additional data will bring tons of new parties flocking to them, so hopefully they are initiating discussions now. They are accelerating TTR02 as the lead MC3 program, and I think it would have caught up to and surpassed PCS as being most advanced MC3 in clinic within 12-18 months anyway.
I am out of my element discussing particulars on the delivery technologies, but this is a compendium of most of their recent advances: http://www.alnylam.com/capella/tag/delivery/
