Bernie, You are correct about Targretin & psoriasis. LGND is deciding on which compounds to move to the next stage of the registration process and they want to see Targretin data on psoriasis before they decide which compound to us in the Phase III trial. I think that there is a somewhat analogous situation with Targretin and Panretin activity against several tumor types. I expect that press releases will be tied to advancement to pivotal trials, and that will dtermine the timing and order of announcements, which may be somewhat dependent on discussions with the FDA.
A good example could be Panretin in Phase III trials for APL. I expected a simple expansion of the Phase II trial, but LGND is actually doing a Panretin/Vessinoid comparision. I'm not sure if there is a second Phase III trial (possibly using patients who have failed prior therapies since the current one targets new patients), and I'm not sure if the FDA suggested the comparitive trial, or LGND chose the tougher end point to show the superiority of their approach (in which they should have a huge lead in the side effects area).
