Undisclosed pipelines continues to build surrounding Peregrine collaborations it seems and remember John Stafford ex Director over at Xencor and BIG PPHM investor! Now Xencor has ties with 3 undisclosed networks 1) Jannsen 2) Alexion 3) Merck http://www.xencor.com/pipeline/ ...there goes that Merck again where we just seen Merck with undisclosed pipeline with Moderna How many undisclosed pipelines are there in total? Dozens I would say ...and Peregrine has dozens of collaborations! A wonderful not so coincidental fact I would say : )
