Low PSMA SUV Boost (LPS-Boost): Intensified 177Lu-PSMA-617 Treatment for Patients With Metastatic Castrate-Resistant Prostate Cancer With Low PSMA Expressing Disease
This phase II trial tests how well 177Lu-PSMA-617 works in treating patients with prostate cancer that has spread from where it first started (primary site) to other places in the body (metastatic) and that remains despite treatment (resistant). Lutetium Lu 177 (177Lu), the radioactive (tracer) component being delivered by prostate-specific membrane antigen (PSMA)-617, has physical properties that make it ideal radionuclide (imaging tests that uses a small dose tracer) for treatment of metastatic castrate-resistant prostate cancer (mCRPC). 177Lu-PSMA-617 works by binding to prostate cancer cel
