Dabrafenib Plus Trametinib for BRAF V600E-Mutant Non-small Cell Lung Cancer: A Patient Case Report.


ABSTRACT: Dabrafenib plus trametinib is US Food and Drug Administration approved combination therapy for use in patients with BRAF V600E-mutant non-small cell lung cancer, but information on use outside of clinical trials is limited. We report the case of a 70-year-old Asian woman (never smoker) who was diagnosed with lung adenocarcinoma in May 2014. Testing at diagnosis was negative for programmed death ligand 1 or EGFR, ALK, and ROS1 alterations. She was started on carboplatin-pemetrexed-bevacizumab and maintenance bevacizumab but progressed in September 2015. Subsequently, she progressed on second-line nivolumab and third-line docetaxel. In March 2016, pleural fluid obtained at diagnosis tested positive for the BRAF V600E mutation and she received dabrafenib plus trametinib. She experienced rapid tumor shrinkage and symptom improvement and became able to participate in regular daily activities with no notable adverse events. In December 2016, she died from a hemorrhagic stroke considered unrelated to treatment. In this heavily pretreated patient with non-small cell lung cancer, dabrafenib plus trametinib elicited an excellent response.
