Key clinical point: Treatment with lutetium prostate-specific membrane antigen (Lu-PSMA) therapy at 6.0 GBq and 7.4 GBq yielded similar PSA response rates and overall survival for patients with progressive metastatic castrate resistant prostate cancer.
Major finding: The primary endpoint of PSA response of at least a 50% reduction from baseline after 2 treatment cycles was met in 28% of the whole cohort, and 46% and 19%, respectively, for treatment regimens of 6.0 GBq and 7.4 GBq.
Study details: The data come from a prospective, phase II trial of 71 men with progressive, metastatic castrate resistant prostate cancer. The patients were randomized to Lu-PSMA therapy at doses of either 6.0 vs 7.4 GBq.
Disclosures: The original study was supported by Endocyte. The researchers had no financial conflicts to disclose.
