Overview

124I-trametinib is a radiolabeled small molecule and positron emission tomography (PET) imaging tracer. It is an iodine-124 labeled analog of trametinib, a potent allosteric inhibitor of mitogen-activated protein kinase kinase 1 and 2 (MEK1/2). Developed to visualize and quantify the delivery and distribution of trametinib to tumors and healthy organs, this radiotracer serves as a tool for personalizing treatment doses and monitoring the emergence of resistance in patients with MAPK-driven malignancies, such as BRAF-mutant melanoma and anaplastic thyroid cancer. By acting as a molecular probe, it allows for noninvasive assessment of the therapeutic index and drug delivery in vivo.
