Results from the phase III BEACON CRC trial show significant improvements in overall survival and objective response rates for the BRAFTOVI Triplet and BRAFTOVI Doublet combination (BRAFTOVI and cetuximab), compared to cetuximab plus irinotecan-containing regimens (Control), and provide analysis of the efficacy and safety of the BRAFTOVI Triplet compared to the BRAFTOVI Doublet.

The trial evaluates the combination of Braftovi (encorafenib), Mektovi (binimetinib), and cetuximab (Braftovi Triplet), in patients with advanced BRAFV600E-mutant metastatic colorectal cancer, following one or two lines of therapy.

Pfizer sponsors the trial.

BRAFTOVI Triplet showed a median OS of 9.0 months, compared to 5.4 months for Control. An improved ORR of 26% was observed in BRAFTOVI Triplet compared to 2% for Control.

These data were presented Sept. 30 at ESMO.

The company expects to submit the results of the trial for marketing approval in the United States in Q4 2019.

How JCO sustains landmark oncology research

In modern oncology, important insights from clinical trials often emerge years after initial publication. As new therapies extend survival and transition more patients into long-term remissions, clinicians and researchers are increasingly looking beyond initial response rates to understand durability, long-term safety, and even the possibility of a cure.
