Encorafenib, cetuximab, and binimetinib are targeted therapies developed for metastatic colorectal cancer with a BRAF V600E mutation. The case highlights the potential use of BRAF V600E targeted therapy in BRAF V600E-mutated duodenal cancer and the importance of molecular profiling in rare cancers. Further research is needed on the effect and safety of targeted therapy for small bowel adenocarcinoma.

Interestingly, these so-called NaJa lines displayed distinct differentiation states and responses to the clinically relevant RAF inhibitors (RAFi) encorafenib and exarafenib, thereby resembling the clinical heterogeneity of BRAFV600E-driven CRC. RAFi resistance was overcome by the EGFR-family inhibitor afatinib...Upon re-transplantation into syngeneic mice, all NaJa lines established aggressive tumors with distinct tumor microenvironments matching to their differentiation states. Thus, the NaJa lines provide a unique tool to study tumor heterogeneity, drug resistance and the interplay between tumor, stroma and immune cells in BRAFV600E-driven CRC.

The oral drug combination was well tolerated with no dose-limiting toxicity or need for dose reduction over the 4 year period. The Avutometinib and Defactinib combination may represent a new standard treatment option for platinum-resistant and AI-resistant/recurrent LGSOC who have failed other MEKi.

The greatest benefits of encorafenib plus binimetinib were observed in patients with evidence of high TMB and/or tumor immune infiltration, suggesting potential immune contributions to efficacy, which were not observed with vemurafenib. BRAF V600 detectability in ctDNA appears to have utility as a marker of prognosis and response in this population.
