I looked at PGNX old PR's and they do not state P values in the couple I saw so probably I am making too much out of it.
I would still like to see the full dataset to compare. If the oral data is comparable to the sub-q then I don't see any huge competitive advantage (for either company). One thing to Keep in mind is AstraZenca is running trials in multiple patient populations and so could get a broader label (if the drug is eventually approved).
My comment earlier to vinmantoo was about it chronic use of the drug in general. I got the impression you take the drug each time you want to go and it works within 4 hours or so (if its going to work). As opposed to Nektar's drug which is intended to offset the constipation side-effects of the opioids and make the person more regular in general. Perhaps a subtle but to me a very important distinction.
