I know that the rad inhibits sugar uptake in the cancer cells. I had a friend on it and he had some response and few side effects. As for erbitux, rash is the most common side effect. Use elidel cream, cetaphil lotion and tetracycline (net rx from Dr.) for side effects. Belieive me I had 15 cycles of panitumumab (vectibix) very similar drug, during clinial trials in 2006 , you want to take care of the rash. Best of Luck
