Molecular Tumor Board Case Series: Targeting KRAS G12C in Lung Cancer

Next-generation sequencing (NGS) identifies biomarkers with prognostic and predictive importance in patients with cancer. The enormous amounts of data generated by comprehensive NGS adds complexity to the identification of valid drug therapy targets. Rapid progress made in targeted drug development creates the need for novel methods to access these treatments for patients. Molecular tumor boards (MTB) not only aid in identifying targetable gene mutations by carefully reviewing NGS data, they can also take lead in creating patient access to the appropriate targeted therapy. Here we describe two patients with Kirsten Rat Sarcoma (KRAS) G12C mutation positive lung adenocarcinoma for whom MTB was able to procure AMG510 or sotorasib, a covalent KRAS G12C inhibitor, by expanded access program ahead of FDA approval.
