Panelists discuss how the increased use of androgen receptor–targeted therapy in clinical practice may impact the effectiveness of PARP inhibitor combinations like talazoparib in the TALAPRO-2 study, while also addressing safety concerns, potential differences in trial populations, and the need for future studies to optimize treatment approaches for various metastatic prostate cancer patient subgroups.

Panelists discuss how the PROfound trial (NCT02987543) demonstrated the efficacy and safety of olaparib monotherapy in metastatic prostate cancer patients with homologous recombination repair gene alterations, highlighting its potential as a targeted treatment option and its impact on the landscape of precision medicine in prostate cancer management.

Panelists discuss how PARP inhibitor monotherapy trials like TALAPRO-1 (talazoparib) and TRITON-3 (rucaparib) have demonstrated efficacy and safety in treating metastatic prostate cancer patients with homologous recombination repair gene alterations, providing important insights into targeted therapy options for this specific patient population.

Panelists discuss how the PEACE III trial findings demonstrate the superiority of combining radium-223 with enzalutamide in treating metastatic castration-resistant prostate cancer, highlighting improved efficacy, the critical importance of bone-protective agents in reducing fracture risk, and the potential for this triplet therapy to become the new standard of care over enzalutamide alone.

Panelists discuss how combining radium-223 with androgen receptor–targeted therapy like enzalutamide addresses historical challenges in treating metastatic castration-resistant prostate cancer, including poor radium-223 uptake, prostate-specific androgen–level control issues, and the need for multimodal treatment approaches.
