A recent late-stage trial published in The New England Journal of Medicine and presented at the American Society of Clinical Oncology’s annual meeting revealed that a combination drug treatment significantly extended survival for patients with a challenging form of colorectal cancer. This innovative treatment includes standard chemotherapy, the antibody drug cetuximab, and Pfizer’s Braftovi, which specifically targets the BRAF V600E mutation affecting about 10% of colorectal cancer patients. Traditionally, patients with this mutation face grim outcomes, surviving less than a year post-diagnosis and often showing poor responses to standard chemotherapy.
The trial, conducted with over 600 patients with metastatic colorectal cancer and the BRAF mutation, randomized participants to receive either the three-drug combination or standard chemotherapy, with some in the latter group receiving bevacizumab. Results were promising: those on the combination treatment lived an average of 30 months compared to 15 months for those on standard therapy. Furthermore, nearly 47% of patients in the treatment group exhibited no disease progression after two years. The FDA granted the combination therapy fast-track approval, contingent on further efficacy data, highlighting its potential as a first-line treatment.
Experts including Dr. Christopher Lieu and Dr. Scott Kopetz hailed the findings, suggesting this could set a new standard of care for the specific mutation. Personal stories, such as that of Laurie Ritchie, a patient who began the combination treatment in October 2023 and experienced remarkable results, emphasize the treatment’s potential to transform patient experiences. With colorectal cancer being a leading cancer diagnosis in the U.S., these findings mark a significant breakthrough in improving survival outcomes for a previously hard-to-treat patient group.
