BRCAAway OS Update: Abiraterone + Olaparib Extends Survival by 5 Years in HRRm mCRPC

The BRCAAway trial brings strong new data on treating metastatic castration-resistant prostate cancer, or mCRPC, in patients with specific DNA repair defects known as homologous recombination repair mutations, or HRRm. This phase 2 study tested abiraterone alone, olaparib alone, or the two drugs together as first-line therapy. It focused on patients with germline or somatic […]

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 […]

BrUOG360 Phase Ib/II Trial: Copanlisib Plus Rucaparib for mCRPC With HRD

Copanlisib combined with rucaparib demonstrates tolerability and early signals of activity in metastatic castration-resistant prostate cancer (mCRPC), according to results from the BrUOG360 phase Ib/II trial published in late 2025. ​Metastatic castration-resistant prostate cancer with homologous recombination deficiency (HRD) responds to PARP inhibitors like rucaparib, but many patients develop resistance through alternative DNA repair pathways.
