Can anyone explain to me why afinitor is used only after the VEGF drugs have failed? I understand the FDA has approved it only this way, but why? Is it just a newer drug that came late to the party? I've seen charts showing it less effective, but I think those charts were all in a setting of being the second thing tried. Has it just not been tested yet as a first line?
I'm trying to compare the effectiveness of these two drugs, and it appears the data may not be there since the VEGF drugs like votrient and sunitib, etc. are all tried first.
