VISION: An International Prospective Open Label Multicenter Randomized Phase 3 Study of 177Lu-PSMA-617 in the Treatment of Patients With Progressive PSMA-positive Metastatic Castration-resistant Prostate Cancer (mCRPC)

Study Overview

The purpose this study is to compare overall survival (OS) in patients with progressive PSMA-positive mCRPC who receive 177Lu-PSMA-617 in addition to best supportive/best standard of care versus patients treated with best supportive/best standard of care alone.

Study Description

Patients with PSMA positive scans will be randomized in a 2:1 ratio to receive either 177Lu-PSMA-617 plus best supportive/best standard of care or to receive best supportive/best standard of care only. Best supportive/best standard of care will be determined by the treating physician/investigator but will exclude investigational agents, cytotoxic chemotherapy, other systemic radioisotopes, and hemi-body radiotherapy. Novel androgen axis drugs [NAADs] (such as abiraterone or enzalutamide) are allowed. The study is open-label and patients will be monitored throughout the 6 to 10-month treatment period for survival, disease progression, and adverse events. A long-term follow-up period will include the collection of survival and treatment updates, adverse events assessment, as well as blood for hematology and chemistry testing. During follow-up, patients will be contacted every 3 months (?1 month) via phone, email, or letter for 24 months or until the the overall censoring rate for survival reduces to a level identified in the SAP. An End of Treatment visit should occur once a patient is to enter the long term follow up. This visit should occur approximately 30 days from the last dose of 177Lu-PSMA-617 or best supportive/best standard of care, but before the initiation of subsequent anti-cancer treatment, outside of what is allowed on study. The planned enrollment for this study is 750 patients.
