Comments: |

BIBW 2992 is a highly potent and irreversible inhibitor of the EGFR and HER2 tyrosine
kinases.
BIBW 2992 inhibits EGFR/HER2 tyrosine kinases both in vitro and in vivo. The in vitro
potency of BIBW 2992 has been determined in enzymatic assays using the human EGFR and
HER2 protein kinase domains as well as in cellular assays measuring the inhibition of either
receptor phosphorylation or proliferation. The potency of BIBW 2992 on the EGFR and
HER2 kinases revealed IC50 values of 0.5 nM and 14 nM, respectively. BIBW 2992 is highly
selective for these kinases and no additional inhibition of other kinases has been observed.
The inhibitory activity of BIBW 2992 on EGFR and HER2 was confirmed at the cellular
level. This compound prevents EGF-stimulated transphosphorylation and induces the
dephosphorylation of constitutively activated HER2, in different cell lines, in the nanomolar
range.
In summary, BIBW 2992 is effective in mechanism and disease-related in vitro and in vivo
models. Tumor regression was achieved in all models upon treatment with BIBW 2992. The
necessary maximum plasma concentration in nude mice to reach this effect was 300 nM.
Thus, BIBW 2992 is a potent, irreversible, orally available EGFR/HER2 tyrosine kinase
inhibitor displaying significant anti-tumor activity in a once daily dosing schedule.
BIBW 2992 did not show relevant inhibition of cytochrome P450 isoenzymes. However,
BIBW 2992 is a CYP3A4 substrate (U05-1723-01), although this metabolic pathway is not
the dominant one. Therefore, drug-drug interactions with CYP3A4 inducers or inhibitors are
not expected.
