PET/CT Imaging of GRPR Expression in Various Tumors
This open-label imaging study will evaluate \[⁶⁸Ga\]-LY4257529 PET/CT, a gastrin-releasing peptide receptor (GRPR)-targeted radiopharmaceutical, in patients with cancers known or suspected to express GRPR. Up to 60 participants will be enrolled in two cohorts: 30 patients with breast cancer and 30 patients with other selected malignancies, including prostate, ovarian, pancreatic, small-cell lung, head and neck squamous cell carcinoma, and other tumors with documented GRPR expression.
