Stintzing S, von der Heyde E,  Wierecky Jan, et al. Background: BRAF V600E-mutant metastatic colorectal cancer (mCRC) is associated with a poor prognosis and limited clinical data. Based on results from the BEACON CRC trial, targeted treatment with encorafenib plus cetuximab (E+C) is available as a standard of care for these patients (pts) after prior systemic...

Ellis H, Klempner S, Quintanilha J, et al. Background: The KEYNOTE-177 randomized controlled trial demonstrated that mCRC patients with MSI high (MSI-H) and/or deficient MMR (dMMR) have better outcomes on first-line ICI than chemotherapy. This study aimed to evaluate MSI by next-generation sequencing (NGS) as a predictive biomarker of ICI effectiveness in real-world settings, and compare...

Fernandez Montes A,  Elez E, Graña B, et al. Background: BRAFV600E mutant metastatic colorectal cancer (mCRC) has a poor prognosis. The BEACON trial demonstrated an improvement in tumor response, overall survival (OS), and progression-free survival (PFS) when administering encorafenib-cetuximab (EC) to patients (pts) who progressed after 1 or 2 therapy lines. This study provides a retrospective analysis...

Kopetz S, Bekaii-Saab TS,  Yoshino T, et al. Background: Among patients with MSI-H/dMMR CRC, BRAF mutations occur in approximately 30%. MSI-H/dMMR and BRAF mutations are both associated with poor prognosis; in patients who have both biomarkers, poor prognosis is thought to be driven by the BRAF mutation. Pembrolizumab is indicated for the treatment of patients with MSI-H/dMMR unresectable or metastatic CRC (mCRC)....

Morris VK, Guthrie KA, Kopetz S, et al. Background: Patients with microsatellite stable (MSS), BRAFV600E metastatic colorectal cancer (mCRC) experience poor survival outcomes. Treatment with the BRAF inhibitor encorafenib (E) and anti-EGFR antibody cetuximab (C) is an approved treatment combination, with a reported overall response rate (ORR) of 20% and median progression-free survival (PFS) of 4.1 months. Anti-PD-1...

Kotani D, Kagawa Y, Matsubara Y, et al. Background: The BEACON CRC trial demonstrated survival benefit of combination therapy with encorafenib (ENCO) + cetuximab (CET) +/- binimetinib (BINI) in patients with RAS wild-type (WT)/BRAF V600E mutant metastatic colorectal cancer (mCRC). However, prognosis of those patients still be poor after the refractoriness to the BEACON combination therapy. One of resistant...

Vakkalagadda C, Mukit S, Kocherginsky M, et al. Background: BRAF mutations drive 5-10% of colon cancers. BRAF + EGFR inhibition with encorafenib + cetuximab is standard second-line therapy, per the BEACON trial, but responses are short-lived. Autophagy induction is implicated as a mechanism for this acquired resistance to therapy. Preclinical models have shown that BRAF inhibition...

Kopetz S,  Yoshino T,  Kim TW, et al. Background: Based on the phase 3 BEACON study (NCT02928224), BRAF inhibitor (i) encorafenib (E) + EGFRi cetuximab (C) was approved for the treatment (tx) of previously treated patients (pts) with BRAFV600E mCRC, with mPFS of 4.3 months (mo) and ORR of 19.5%. In the phase 2 ANCHOR study (NCT03693170), mPFS...

Tabernero J, Prager GW,  Fakih M, et al. Background: Trifluridine/tipiracil (FTD/TPI) plus bevacizumab (Bev) demonstrated promising efficacy in a randomized phase 2 trial of heavily pretreated patients (pts) with metastatic colorectal cancer (mCRC). SUNLIGHT was conducted to confirm these findings. Methods: The global phase 3 SUNLIGHT study enrolled pts aged ≥18 years with histologically confirmed...

El-Khoueiry A, Fakih M, Gordon MS, et al. Background: BOT promotes optimized T cell priming, activation and memory formation by strengthening antigen presenting cell/T cell co-engagement. As an Fc-enhanced next-generation anti–CTLA-4 antibody, BOT also promotes intratumoral regulatory T cell depletion and reduces complement fixation. We present results from patients with MSS CRC treated with BOT +...
