Treatment of Patients With Progressive mCRPC With 177Lu-PSMA-617

Summary

The purpose of this study is to evaluate the safety and tolerability of Lutetium-177-PSMA-617 (PLUVICTO) in patients with metastatic castration-resistant prostate cancer (mCRPC) and extensive bone metastases, which appear as a "super scan" pattern on a bone scan. Pluvicto is FDA-approved, but patients with super scan bone scans were previously excluded from the VISION clinical trial, leaving a knowledge gap. The study will enroll up to 30 men with metastatic castration-resistant prostate cancer, with an initial dosing approach that differs from the standard dose. The safety and tolerability of PLUVICTO will be evaluated in this study, with a focus on identifying the optimal dose for this population. This study addresses an important gap in understanding how Pluvicto performs in mCRPC patients with super scan findings.
