Abstract

TPS3622 Background: BRAF mutations are found in ≈10% of mCRC cases. Pts with BRAFV600E mCRC have a poor prognosis, with shorter progression-free survival (PFS) and overall survival (OS) than pts with BRAFwt mCRC (Van Cutsem et al 2011; Modest et al 2012; Sorbye et al 2015). The benefits of combined BRAF + EGFR inhibition in mCRC have been demonstrated in vitro (Corcoran et al 2012; Prahallad et al 2012; Yang et al 2012), and preclinical evidence suggests that adding MEK signaling inhibition improves antitumor activity. Early clinical data indicate that BRAF + EGFR + MEK inhibition has greater activity than BRAF + EGFR inhibition in pts with BRAFV600E mCRC (Van Cutsem et al 2016). Our study ..
