68Ga-gozetotide (68Ga-PSMA-11) is used to identify prostate-specific membrane antigen (PSMA)-positive tumors on PET scans. In the VISION study, 68Ga-PSMA-11 was used to determine the eligibility of patients with metastatic castration-resistant prostate cancer for treatment with 177Lu-vipivotide tetraxetan (177Lu-PSMA-617), based on predefined read criteria.

The pivotal phase 3 VISION study used [68Ga]Ga-PSMA-11 (also known as 68Ga-PSMA-11) imaging to identify patients with metastatic castration-resistant prostate cancer eligible for [177Lu]Lu-PSMA-617 radioligand therapy, based on predefined read criteria. In this substudy of VISION, the inter-reader variability and intra-reader reproducibility of visual assessments of 68Ga-PSMA-11 positron emission tomography scans using the VISION read criteria were evaluated.
BACKGROUND
Metastatic castration-resistant prostate cancer remains fatal despite recent advances. Prostate-specific membrane antigen (PSMA) is highly expressed in metastatic castration-resistant prostate cancer. Lutetium-177 (177Lu)–PSMA-617 is a radioligand therapy that delivers beta-particle radiation to PSMA-expressing cells and the surrounding microenvironment.

Purpose of the study: To report the safety evaluation of 177Lu-PSMA-617 derived from the cohort of 64 patients exposed to 177Lu-PSMA-617 in the RESIST-PC trial NCT03042312 Methods: RESIST-PC was a prospective multicenter phase 2 trial.

Objective: To determine prospectively the efficacy profile of 2 activity regimens of Lu-PSMA therapy in patients with progressive metastatic castrate resistant prostate cancer (mCRPC): 6.0 vs 7.4 GBq.
