First Human Trial of Targeting MDM2/MDMX PET Imaging

"Utilizing a peptide with high affinity to MDM2/MDMX as the targeting moiety for radiopharmaceuticals, this study explores the diagnostic efficacy of \[68Ga\] MDM2/MDMX Peptide in patients with malignant tumors exhibiting high MDM2/MDMX expression. This approach not only provides a basis for the early diagnosis of malignant tumors but also facilitates the formulation of effective precision therapy strategies tailored to the tumor's MDM2/MDMX expression profile, particularly for patients with recurrent and metastatic disease.~\[68Ga\] MDM2/MDMX Peptide, a novel MDM2/MDMX-targeted molecular probe labeled with 68Ga, utilizes DOTA as a bifunctional chelator for complexing with 68Ga3+. The labeling process is straightforward, allowing for direct use without purification, and demonstrates high in vivo stability."
