You brought a good point. I think this is a point many people miss. Let's say Zytiga is approved for 1st line CRPC, sooner or later, they will need another treatment. At the moment, I am not sure taking MDV3100 after Zytiga makes too much sense. Even if it does, they will need another treatment after that. They can either go with chemo, or it opens door for alpharadin and/or Cabozantinib. IMO Zytiga/MDV3100 moving to earlier line of CRPC is good news for other players in CRPC. Not sure about Provenge because its place is before Zytiga/MDV3100.
