CP, Interesting statement - on what would you base this assertion?
biopharm, I think he sitting in that GILD CEO position may well close the door for GILD completely when it comes to working with PPHM.
GILD is desperately in need of that new "Cornerstone Molecule" as we are all well aware. If PPHM has it - then your statement would seem to make absolutely no sense whatsoever.
It seems Gilead is interested in PPHM ex-employees... here is another:
but first...this is just from Roche below, and talks of the recovery process of molecules and I think Avid Bioservices can attain purity levels of unseen proportions vs others, and may hold some clues in why/how Avid is/will advance fast.
Its one thing to be able to even have the ability to create a living cell bank and increase purity by 625% from that of the original, but when I read the below.... when I read the words "drug" I can only think of PS Targeting Mabs, because if I was to go through all this trouble I'd want to do it with a drug that has such a unique binding property, such a unique dual MOA (targets flipped PS and boosts the immune system ) and my oh my.... this individual started out in Tustin at Peregrine/Avid.
What other "drug" could they be referring to that they bring in a contractor out of school for such activities ?? maybe a contractor with a little PS Targeting Mab handling experience...hmmmmm
Hundreds of therapeutic monoclonal antibodies (mAbs) are currently in development, and many companies have multiple antibodies in their pipelines. Current methodology used in recovery processes for these molecules are reviewed here. Basic unit operations such as harvest, Protein A affinity chromatography and additional polishing steps are surveyed. Alternative processes such as flocculation, precipitation and membrane chromatography are discussed. We also cover platform approaches to purification methods development, use of high throughput screening methods, and offer a view on future developments in purification methodology as applied to mAbs.

I think its all about PS Targeting and could we have a little tug of war going on between AstraZeneca and Gilead in their PI3K approach, which just may be completely PS Targeting and that is what Gilead is trying to confirm possibly when they say "ligand-binding ability of drug" and that drug is very likely a PS Targeting drug.
Still interesting, is that Gilead files patent for a what looks like a PI3K PS Targeting approach... back in December of 2012 and all of a sudden we now see the AstraZeneca surprise news with Peregrine but notice how they (AZ) are also picking up Acerta Pharma that comes with a PI3K target. They both just may be PS Targeting....
