Grothey Shares Encouraging Data from Lead-In Phase of BEACON CRC Trial

Axel Grothey, MD, discusses the results from the safety lead-in phase of the BEACON CRC trial investigating the triplet regimen of BRAF inhibitor encorafenib, MEK inhibitor binimetinib, and anti-EGFR antibody cetuximab in&nbsp;patients with&nbsp;<em>BRAF</em>V600E-mutant metastatic colorectal cancer.

Axel Grothey, MD, medical oncologist at West Cancer Center, discusses the results from the safety lead-in phase of the BEACON CRC trial investigating the triplet regimen of BRAF inhibitor encorafenib (Braftovi), MEK inhibitor binimetinib (Mektovi), and anti-EGFR antibody cetuximab (Erbitux) in patients withBRAFV600E-mutant metastatic colorectal cancer (mCRC).

Out of the 30 patients available for the safety analysis, 29 were available for efficacy. There was a response rate of 48% among these patients. Also, not one patient had progression of disease by RECIST criteria in this analysis.

The median progression-free survival is 8 months in this patient population, which far exceeds historical controls of about 2 to 4 months. Additionally, the median overall survival is 15.3 months, which is almost 3 times as long as current standards of care. Grothey notes that this is much longer than seen with other biologic combinations in this setting.
