How to use

In Vitro:

Lifirafenib (BGB-283) potently inhibits BRafV600E-activated ERK phosphorylation and cell proliferation. It demonstrates selective cytotoxicity and preferentially inhibits proliferation of cancer cells harboring BRafV600E and EGFR mutation/amplification. In BRafV600E colorectal cancer cell lines, Lifirafenib (BGB-283) effectively inhibits the reactivation of EGFR and EGFR-mediated cell proliferation.

In Vivo:

Lifirafenib (BGB-283) treatment leads to dose-dependent tumor growth inhibition accompanied by partial and complete tumor regressions in both cell line-derived and primary human colorectal tumor xenografts bearing BRafV600E mutation.
