177Lutetium-PSMA-617 in Metastatic Castration-Resistant Prostate Cancer; Randomized Controlled Phase 3 Trial Data is Pending and Novel Combinations are Being Tested
177Lu-PSMA-617 has been introduced before in this column as a PSMA-targeted radioligand therapy.1 A Phase II Australian trial treated 30 men with metastatic castration-resistant prostate cancer who had variable lines of exposure to agents such as abiraterone, enzalutamide, docetaxel and/or cabazitaxel.2 Seventeen (57%) patients achieved a prostate-specific antigen (PSA) decline ≥50%. Fourteen (82%) of 17 patients with measurable disease had an objective response. Toxicities were generally mild with grade 1 dry mouth in 26 (87%) patients, grade 1/2 transient nausea in 15 (50%) patients and grade 1/2 fatigue in 15 (50%) patients. Grade 3/4 events were rare, but thrombocytopenia did reach that level in 4 (13%) patients.
