Trial Outcomes & Findings for 68Ga-PSMA-11 PET/CT Screening Prior to 177Lu-PSMA-617 Therapy for Patients With Metastatic Castrate Resistant Prostate Cancer (NCT NCT05547386)

NCT ID: NCT05547386

Last Updated: 2025-07-18

Results Overview

Safety of gallium Ga 68 gozetotide \[68Ga-prostate-specific membrane antigen (PSMA)-11\] assessed by the number of patients reporting unexpected adverse reactions from the time of injection until the time they leave the care of the division of nuclear medicine. If any adverse reactions are reported, the patient will be evaluated by a nurse and/or physician and will receive appropriate care. The principal investigator (PI) or those designated by the PI will ascertain the severity of the adverse event and how likely the adverse reaction was associated with the injected 68Ga-PSMA-11.
