Pfizer is working to increase awareness among doctors about testing for a rare lung cancer mutation, aiming to boost the use of its drug Braftovi, which it hopes will become the standard of care. At a recent conference, the company presented three-year data from a Phase 2 study on patients with BRAF V600E-mutant metastatic non-small cell lung cancer. Those treated with Braftovi, in combination with another Pfizer drug, Mektovi, had a median progression-free survival of over two-and-a-half years. This suggests the treatment can significantly delay the worsening of cancer.
Chris Boshoff, Pfizer's Chief Oncology Officer, stated that the data supports Braftovi as a standard treatment for this patient group. Approximately 2% to 3% of lung cancer patients have the BRAF mutation. Currently, the standard of care includes immunotherapy and chemotherapy, but fewer than 50% of U.S. lung cancer patients are tested for the mutation, with even lower rates globally. Boshoff emphasized that testing for BRAF mutations could be done through a simple blood test, covered by insurance in the U.S.
Pfizer sold nearly $400 million worth of Braftovi and Mektovi last year. The company also sees potential growth in colorectal cancer, where BRAF mutations are present in 10% of cases, with data from a late-stage study expected by year-end. Pfizer is focusing on global efforts to encourage testing and educate healthcare professionals, patients, and advocacy groups.
