BRAF Mutations in CRC
• BRAF es el primer efector de lasseñales de KRAS (cromosoma 7)– Ocurre con más frecuencia en exon 15
(V600E)
– Aparece en 4%-8% de los pacientes con CCRm
– Mutuamente exclusiva con la mutaciónRAS
– Pronóstico negativo con mediana OS de 10 meses
– Más frecuente en mujeres, ancianos, colon decho, alto grado histológico
– Mas frecuente la diseminación peritoneal y ganglionar

– Determinación: Puede determinarse por dos métodos en tumor:
– Pérdida de expresión por IHQ de alguna de las proteínas
reparadoras de DNA, hMLH1, hMSH2, hMSH6 y hPMS2.
– Existencia de Inestabilidad de microsatélites por PCR.

BRAF INHIBITION IN mCRC
Adapted from Van Geel et al. ASCO 2014
1. Corcoran et al. Nature 2012, 2. Prahallad et al. Cancer Discovery 2012
EGFR signaling is inhibited by hyperactive BRAF. In the presence of BRAF inhibitor, EGFR
signaling is reactivated either by the BRAF-MEK pathway or the PI3K-AKT pathway,
resulting in cellular proliferation and survival1,2

ANCHOR-CRC will investigate the cetuximab + encorafenib + binimetinib combination in 1st-line BRAF mt mCRC
ANCHOR-CRC1,2: a multicenter, open-label, single-arm Phase II study to evaluate the antitumor activity of the combination of binimetinib + encorafenib + cetuximab in adults with previously untreated BRAF V600 mt mCRC
• The study is recruiting: estimated primary completion date is June 2020
Primary endpoint: confirmed ORR based on local tumorassessment
Secondary endpoints: confirmed ORR based on central tumorassessment; ORR, DOR, TTR, PFS, OS (all based on local and central tumor assessment); safety; pharmacokinetic parameters; quality of life
Key inclusion criteria: RAS wt, BRAF V600E* mCRC with measurable disease; no prior systemic therapy for metastatic disease
Key exclusion criteria: previous treatment with RAF, MEK or EGFR inhibitors; symptomatic brain metastases or leptomeningeal disease; retinal vein occlusion (or risk factors for); Crohn’s disease, inflammatory bowel disease, or impaired cardiovascular function
*BRAF mt status must be determined in tumor tissue by PCR or NGS local assay prior to screening, and confirmed by the central laboratory2
CR, complete response; PR, partial response.
Patients with BRAF V600E mCRC who have had no prior treatment for metastatic disease
Cetuximab 400mg/m2 i.v cycle 1, day 1, 250mg/m2 q1w for the first 28 weeks, then 500mg/m2 q2w from Week 29
(cycle 8, day 1) + encorafenib 300mg q1d PO + binimetinib45mg BID PO (40 subjects to be treated)
STUDY DESIGN
If ≥12 patients achieve CR or PR, 50 additional
patients will be treated
If ≤11 patients achieve CR or PR, the study will be
stopped
Treatment will be given in 28-day cycles until disease progression, unacceptable toxicity, initiation of subsequent
anticancer therapy, death, or withdrawal of consent
