Sotorasib in Combination With Trastuzumab Deruxtecan for the Treatment of Locally Advanced and Metastatic Non-small Cell Lung Cancer With a KRAS G12C Mutation

This phase I/II trial tests the safety, side effects and best dose of sotorasib with trastuzumab deruxtecan and how well the combination works in treating patients with KRAS G12C mutated non-small cell lung cancer that has spread to nearby tissues or lymph nodes (locally advanced) or that has spread from where it first started (primary site) to other places in the body (metastatic). Sotorasib blocks a protein made by the mutated KRAS gene (KRAS p.G12C), which may help keep tumor cells from growing and may kill them. It is a type of targeted therapy. Trastuzumab deruxtecan is in a class of medications called antibody-drug conjugates. It is composed of a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called deruxtecan. Trastuzumab attaches to HER2 positive tumor cells in a targeted way and delivers deruxtecan to kill them. Giving sotorasib in combination with trastuzumab deruxtecan may be safe, tolerable, and/or effective in treating patients with locally advanced or metastatic non-small cell lung cancer with a KRAS G12C mutation.
