The purpose of this study is to evaluate the efficacy of \[177Lu\]Lu-PSMA-617 over a change of androgen receptor-directed therapy (ARDT) treatment in prolonging radiographic progression free survival (rPFS) in Chinese metastatic castration-resistant prostate cancer patients, who were previously treated with another ARDT as last treatment and who have not been exposed to a taxane-containing regimen in castrate resistant prostate cancer (CRPC) or hormone-sensitive prostate cancer (HSPC) settings and who are considered appropriate for delaying taxane-based chemotherapy. The primary endpoint of rPFS will be assessed via blinded independent centralized review of radiographic images provided by the treating physician and as outlined in Prostate Cancer Working Group 3 (PCWG3) guidelines.
Phase 2 trials begin testing efficacy in a larger patient group (100–300). This is often where biotech binary events occur — positive Phase 2 data can significantly advance a company's pipeline narrative, while failures can be terminal for a program.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
Novartis AG (NVS) is the sponsoring company for this trial. BiotechSign currently grades this company D (36/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
