Clinical Trial Summary

A Multi-Center, Open-Label, Randomized Phase 3 Trial Comparing the Safety and Efficacy of 177Lu-PSMA-I&T versus Hormone Therapy in Patients with Metastatic Castration-Resistant Prostate Cancer.

Clinical Trial Description

This is a prospective, open-label, multi-center, randomized, Phase 3 study evaluating Lutetium 177Lu-PSMA-I&T as treatment compared to standard of care hormone therapy in men with metastatic Castration-Resistant Prostate Cancer. The study will include a total of 400 patients with metastatic prostate cancer and documented positive PSMA PET imaging. Patients will be randomized at a ratio of 2:1 to receive either 177Lu-PSMA-I&T or hormone therapy (abiraterone or enzalutamide) respectively. Patients randomized to the investigational product will receive up to 6 treatments every 6 weeks at a dose of 200 mCi (7.4 GBq). All patients will be followed for adverse events and safety labs throughout the course of the study. Progression of disease will be assessed radiographically using Prostate Working Group Criteria 3 (PWGC3) and Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 of conventional imaging as well as PSA levels and symptom recording throughout the course of treatment. 30 patients will participate in a pharmacokinetic and radiation dosimetry sub-study at selected participating clinical sites. Sub-study participants will receive SPECT imaging after each treatment cycle for dosimetry analysis. Sub-study participants will not be randomized. ;
