First-in-human safety, imaging and dosimetry of [68Ga]Ga-DPI-4452, a novel CA IX-targeting peptide, in patients with clear cell renal cell carcinoma. (ASCO-GU 2024) - P1/2 | "[68Ga]Ga-DPI-4452 provides exceptional images in patients with ccRCC without clinically significant toxicity. Very high SUVs and tumor-to-background ratios suggest potential for use in both diagnostics and patient selection for therapy. The tumor retention and rapid elimination support potential of [177Lu]Lu-DPI-4452 radioligand therapy."
