BRCA-Altered mCSPC Progresses Faster on ARPIs: A Real-World Treatment Gap

Recent real-world data clarify how homologous recombination repair (HRR) alterations, especially BRCA1/2 mutations, affect outcomes in metastatic castration-sensitive prostate cancer (mCSPC) treated with androgen receptor pathway inhibitors (ARPIs). In a US cohort of 745 patients, overall differences in time-to-next-treatment (TTNT) and time-to-castration resistance (TTCR) were modest between patients without HRR alterations and those with non-BRCA […]

Phase 2 TALENT Trial: Talazoparib as Monotherapy or With Enzalutamide in HRR-deficient mCRPC

The TALENT trial is a randomized, open‑label, phase 2 trial evaluating whether adding enzalutamide to talazoparib improves outcomes compared with talazoparib alone in men with metastatic castration‑resistant prostate cancer (mCRPC) who have homologous recombination repair (HRR) gene alterations and have progressed after abiraterone‑based therapy. The trial builds on the phase 3 TALAPRO‑2 results, which showed […]

EvoPAR-PR01: Saruparib (AZD5305) Phase III Trial in Metastatic Castration-Sensitive Prostate Cancer

Saruparib (AZD5305), a next-generation PARP1-selective inhibitor, represents a promising evolution in prostate cancer therapy, particularly for metastatic castration-sensitive disease (mCSPC), through the ongoing phase III EvoPAR-PR01 trial. Unlike first-generation PARP inhibitors (PARPi) such as olaparib that target both PARP1 and PARP2, saruparib specifically inhibits and traps PARP1 on DNA damage sites, sparing PARP2 to potentially […]

SPR1020: a Promising PARP1-Selective Inhibitor in Advanced Solid Tumors (Including mCRPC)

A  first-in-human Phase 1/2 trial of SPR1020, a highly selective PARP1 inhibitor, dosed its inaugural patient, igniting hope for patients with advanced solid tumors harboring DNA repair deficiencies. This open-label, multicenter study employs a classic 3+3 dose-escalation design to pinpoint the recommended Phase II dose or maximum tolerated dose, transitioning seamlessly into expansion cohorts tailored […]

AMPLITUDE Trial Update: Niraparib Plus Abiraterone Shows Promise for HRR-Altered Metastatic Prostate Cancer
