Falnidamol (BIBX 1382) is an orally active, reversible, and selective inhibitor of the epidermal growth factor receptor (EGFR) tyrosine kinase. In preclinical studies, BIBX 1382 exhibited potent inhibition of EGFR autophosphorylation with an IC₅₀ of ~10–20 nM in EGFR-overexpressing cell lines such as A431. It effectively blocked downstream signaling pathways, including ERK and AKT, and inhibited proliferation of EGFR-dependent tumor cells with GI₅₀ values in the low nanomolar range. In xenograft models, BIBX 1382 demonstrated significant antitumor activity, especially in tumors with wild-type EGFR and high receptor expression.
