In a significant advancement for treating aggressive colorectal cancer, a combination drug therapy has reportedly doubled patient survival time. This innovative treatment, featuring a standard chemotherapy drug, the antibody drug cetuximab, and Pfizer’s Braftovi—targeting the BRAF V600E mutation—was discussed during recent presentations at the American Society of Clinical Oncology’s annual meeting and detailed in The New England Journal of Medicine. Approximately 10% of colorectal cancer patients exhibit this mutation, which correlates with a poor prognosis, often leading to survival of less than a year after diagnosis.
Initial outcomes from a late-stage trial, involving over 600 patients with metastatic colorectal cancer, revealed that those receiving the three-drug combination lived around 30 months on average, compared to just 15 months for those on standard chemotherapy. Notably, almost 47% of patients on the combination reported no disease progression after two years. This combination therapy, initially approved by the FDA in 2020 for patients after prior treatment failure, has now received fast-track approval as a first-line treatment, given its significant potential to address the pressing medical needs of this high-risk patient group.
Experts, including Dr. Christopher Lieu and Dr. Scott Kopetz, have praised these results, noting the profound impact on patient quality of life and survival rates. Laurie Ritchie, a patient undergoing the new therapy, shared her journey from a shock diagnosis of advanced cancer to a current state of health, free from detectable cancer, highlighting the treatment’s transformative potential. Colorectal cancer remains a major health challenge in the U.S., with over 141,000 new diagnoses expected this year alone.
