I
think a real interesting question would be if you used Herceptin and combined
it with a TK inhibitor for HER2, would you get a greater bang than if
you just used Herceptin alone. We dont have, obviously, any clinical
data and, indeed, theres very little in the way pre-clinical data
at this point. Probably the more interesting ones though are going to
be combinations of Herceptin with tyrosine inhibitors that inactivate
the epidermal growth factor receptor. EGFR, the epidermal growth factor
receptor, preferentially dimerizes with HER2. HER2 itself doesnt
have a ligand, but is the preferential dimerization partner with all the
other members of the epidermal growth factor receptor family. So, a one-two
punch where we shut down Herceptin externally and shut down the epidermal
growth factor receptor internally ¾ since we know that in many cases
EGFR has a truncated form where it, in fact, doesnt have an external
domain ¾ actually it makes a good deal of sense and its certainly
something well worth looking at in the clinic.
