研究概览
简要总结
First in Human (FIH) study to characterize the safety, tolerability, pharmacokinetics (PK), distribution, radiation dosimetry, and anti-tumor activity of [177Lu]-NeoB in patients with advanced solid tumors known to overexpress GRPR and with [68Ga]-NeoB lesion uptake.
详细描述
This study was designed to establish whether the ligand NeoB, a high affinity antagonist for GRPR, could be used in a theragnostic approach for selection and therapy of GRPRexpressing malignancies: radiolabeled with (1) Gallium 68 (68Ga) to identify lesions and with (2) Lutetium-177 (177Lu) for the treatment of these lesions.

Sexually active males must use a condom during intercourse while taking the drug and for 6 months after stopping treatment and should not father a child in this period. A condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid.
