Uncovering the mechanisms of action of 177Lu- and 212Pb- based PSMA radioligand therapies (AACR 2025) - "Introduction: 177Lu-PSMA-617 is the first FDA-approved targeted radioligand therapy (RLT), and in clinical trials, significantly prolonged survival and improved quality of life in patients with metastatic castration resistant prostate cancer (mCRPC). Comparison studies of 177Lu- and 212Pb-PSMA treatment on PC cells showed a higher efficacy of 212Pb-PSMA in vitro and in vivo supporting the clinical application of 212Pb-PSMA for mCRPC. Mechanistic studies furthered the understanding of PC radiobiology and cellular responses to beta- and alpha-RLT with the identification of a cell cycle arrest in PC specifically induced by 212Pb-PSMA."

Phase Ib/IIa dose escalation and expansion study of [212Pb]Pb-ADVC001 in metastatic castration-resistant prostate cancer: TheraPb–phase I/II study. (ASCO-GU 2025) - P1/2 | "The radioligand therapy 177Lu-PSMA-617, which uses a beta-emitting isotope linked to a PSMA-targeting small molecule, has shown a median survival advantage in mCRPC of four months, underpinning the critical need for more effective treatments. If data from Phase 1b demonstrates multiple dosing regimens are reasonably equivalent in terms of safety, tolerability and anti-tumor activity, the Phase 2a expansion study may include adaptive randomization to identify an optimized dose and schedule. The trial is currently enrolling at two clinical sites in Australia."
